short argumentative speech about nature vs nurture

21 Nature vs Nurture Examples

The nature vs. nurture debate is the long-standing argument over whether heredity (nature) or environment (nurture) plays a greater role in developing human characteristics and behaviors. 

Nature refers to the biological characteristics we are born with, including genetic predispositions toward certain traits. In contrast, nurture includes external influences that shape us, such as culture, relationships, and everyday experiences.

For example, when it comes to personality development, some people believe that genetics play a stronger role than environmental factors; this would be considered a nature-focused perspective. 

Others may view the environment as more important. In this case, a nurturing upbringing could help individuals develop their personalities. Therefore, both sides can have valid arguments for their respective positions in the debate.

The Nature Perspective

In the context of the nature vs. nurture debate, nature refers to biological heredity and genetic predispositions inherited by individuals from their parents at birth. 

Buheji (2018) states that:

“in the “nature vs. nurture” debate, nature refers to an individual’s innate qualities (nativism)” (p. 221).

This includes physical characteristics such as eye color, facial features, personality traits, and behavioral tendencies.

Genes determine the unique physical characteristics of each individual while also influencing psychological and social behavior.

Some research implies that roughly 50% of an individual’s personality and disposition are pre-determined by genetics (Bouchard & Loehlin, 2001).

However, Krueger and colleagues (2008) state that the interplay between gene-environment interactions has a consequential effect on one’s character traits. Hence, the heritability of personality isn’t always precisely 50%.

So, nature is the hereditary and genetic characteristics pre-determined at birth and influence a person’s behavior.

The Nurture Perspective

Nurture, in the context of the nature vs. nurture debate, is used to describe environmental factors that influence an individual’s development. 

According to Coon and Mitterer (2014), nurture:

“…refers to the sum of all external conditions that affect a person” (p. 100).

This includes a variety of influences such as parenting style, educational experiences, cultural background, and exposure to different environmental conditions over time.

While “nurture” may naturally invoke ideas of childhood and parental care, environmental components and life experience can shape human mental, emotional, and physical health throughout their lives (Harsha et al., 2020).

For example, lifestyle choices have been found to impact a person’s risk for developing certain diseases and their level of immunity against illness. 

Furthermore, addiction susceptibility can be impacted by environmental factors such as peer group that has been observed throughout an individual’s life (Ducci & Goldman, 2012).

Simply, nurture is an umbrella term for any environmental influences that shape the development of a person’s mental, physical, and emotional health. 

Examples of Nature vs Nurture

Nature examples.

• Eye color : A person’s eye color is determined by their genetic makeup and inherited from their parents.
• Height : As with eye color, height is a physical trait that is determined by a person’s genes and largely determines an individual’s adult height.
• Risk of D iseases : A person’s risk for developing certain diseases can be partially attributed to their genetic predisposition for that illness and influenced by lifestyle factors and personal environment.
• Immune S ystem F unctionality : Genetic predisposition plays an important role in determining an individual’s resistance to disease through the strength of their immune system. However, lifestyle choices can also influence this trait over time (e.g., diet and exercise).
• Hair Color: Hair color is determined by genetic factors. Recessive genes, like the red hair gene, generally have to be present in both parents for the recessive gene to become dominant.
• Balding: Going bald is an inherited trait. Some groups – such as male British Anglo-Saxons – are more likely to go bald in their 30s than the average.
• Adrenaline response : An individual’s ability to react quickly in dangerous situations—their “fight or flight” response—tends to be innate in all of us.

Nurture Examples

• Ethics and Parenting style : An individual’s upbringing and the parenting style they are exposed to can shape their behavior, emotional reactions, and psychological outlook throughout life.
• Linguistic Determinism Theory : In this theory, the language we are taught as a child will determine the ways we think and interact with the world. It goes some way to explaining how people of differing language groups may have differing values and belief systems .
• Values and Cultural background : Depending on their cultural background, different individuals may be exposed to different values and belief systems, which can impact their attitudes toward certain issues or topics/ideas/beliefs.
• Anxiety and Exposure to T rauma : Experiences with violence or traumatic events can have long-term effects on an individual’s psychology which could manifest outwardly as symptoms of anxiety or difficulty coping under pressure in later stages of life.
• Positivity and Social E nvironment : The people an individual interacts with can either positively or negatively affect their development. Individuals need to surround themselves with positive influences while avoiding those that might lead them down the wrong path in life.
• Relationship E xperiences and Sense of Security : Positive relationships throughout a person’s life will tend to improve outlook and well-being. In contrast, unhealthy relationships could leave long-term psychological damage that might need professional help before it can be addressed adequately by an individual suffering firsthand.

Nature and Nurture Examples

• Personality traits: The role of genetics (nature) in determining personality traits, such as extraversion or conscientiousness is balanced against the influence of upbringing and life experiences (nurture).
• Aggression: There is debate over whether aggressive behavior is primarily influenced by genetic factors (nature) or by environmental factors, such as upbringing, social learning , and exposure to violence (nurture).
• Athletic ability: The role of genetics (nature) determines a lot of our natural talent in sports but the importance of training, motivation, and exposure to physical activity (nurture) takes us the rest of the way.
• Musical talent: Musical ability may be affected by genetic predisposition (nature) but also environmental factors, such as exposure to music at a young age, education, and practice (nurture).
• Attachment styles: It is debatable whether a person’s attachment style (secure, anxious, or avoidant) is impacted by genetics (nature) versus the influence of early childhood experiences and caregiver relationships (nurture).
• Empathy and emotional intelligence: The capacity for empathy and emotional intelligence is debatably determined by both genetics (nature) and the result of upbringing, social exposure, and life experiences (nurture).
• Spiritual beliefs: Theological determinism holds that god has pre-selected his chosen people who will be true believers (nature) while others think that belief in god is a choice and we must raise our children to maintain a belief in god (nurture).
• Learning styles: In the 1980s, there was extensive debate over whether preferred learning styles, such as visual, auditory, or kinesthetic, are determined by genetic factors (nature) or influenced by educational experiences and personal development (nurture). Today, most education theorists believe that learning preferences are based on nurture over nature.
• Addiction susceptibility : Scientists have identified genes related to addiction susceptibility, even though this trait is also heavily influenced by the environment (Ducci & Goldman, 2012).
• Intelligence : Education can significantly impact traits such as intelligence levels and knowledge base, with certain experiences inspiring curiosity or creativity in individuals later in life.

Origins of Nature vs. Nurture Debate

The debate surrounding the extent to which human development is influenced by nature (heredity) or nurture (environmental factors) has been around since ancient times.

Plato, the renowned Greek philosopher, argued that beneficial traits in humans were attributable to both nature and nurture. He believed people could adapt to external occurrences throughout their lifetime (Englander, 2010).

However, his mentor Socrates leaned more towards genetics as the primary factor of human development – a notion known as Nativism, which was coined by both philosophers together.

In the late 1800s, Charles Darwin’s theory of evolution and Sir Francis Galton’s article “Hereditary Talent and Character” sparked a resurgence in interest in this topic (Galton, 1865)

So, Galton (1865) suggested hereditary influences to be at least as important as the environment when determining an individual’s outcomes in life.

The debate continued through subsequent decades, with psychologist John B. Watson’s revolutionary suggestion that environment—what he called “nurture”—was more important than hereditary factors or biology (Herrnstein, 1998).

In recent years, researchers have realized that both internal (genetic) and external (environmental) factors play a role in how individuals develop physically and psychologically. 

As such, most experts now subscribe to an approach that looks at how both genetic inheritance and environmental influences work together throughout life to shape each person’s unique character traits and behaviors.

The Role of Epigenetics in the Nature vs. Nurture Debate

Epigenetics is the study of changes in gene expression caused by environmental factors, such as diet and exposure to toxins, without altering the underlying sequences of DNA .

It is an emerging field of research that has been gaining prominence in recent years as scientists try to uncover how and to what extent the environment can shape genetic expression (Harvard University, 2019).

Epigenetic influences are now considered a significant factor in the nature vs. nurture debate, particularly in how individuals develop physically and psychologically throughout life. 

Evidence suggests that epigenetic mechanisms can be used to modulate gene expression depending on the environment, thus having a direct influence on an individual’s characteristics and behaviors (Harvard University, 2019).

This means that while both genetics and environment may play a role in determining an individual’s outcomes in life, epigenetics provides an additional layer of complexity by allowing environmental factors to interact with gene expression.

Nature vs. nurture is a decades-old debate that continues to be studied in various fields. 

Nativists state that genetics play a major role in determining characteristics and behaviors. For example, a person may have inherited certain traits from their family. 

However, empiricists suggest that external factors, such as upbringing and lifestyle choices, can also have a significant influence.

From ancient philosophers to modern-day scientists, this debate has gone through various iterations and continues to evolve today with the introduction of epigenetics. 

More recently, epigenetics have emerged as a key factor in the debate. Its  mechanisms can be used to modulate gene expression depending on the environment, thus having a direct influence on an individual.

So, it appears that both nature and nurture are important factors in determining an individual’s outcomes in life.

Nature is the influence of genetics or hereditary factors in determining the individual’s behavior. In other words, it is how natural factors shape the behavior or personality of an individual. In most cases, nature determines the physical characteristics which in effect influence the behavior of an individual. Physical characteristics such as physical appearance, type of voice and sex which are determined by hereditary factors influences the way people behave.

Nurture on the other is the upbringing of an individual according to the environmental conditions. That is, the way individuals are socialized. Basically, nurture is the influence of environmental factors on an individual’s behavior.

According to this paradigm, an individual’s behavior can be conditioned depending on the way one would like it to be. Often, individuals’ behaviors are conditioned by the socio-cultural environmental factors. It is because of socio-cultural environmental conditions that the differences in the behavior of individuals occur.

Nature determines individual traits that are hereditary. In other words, human characteristics are determined by genetic predispositions which are largely natural. Hereditary traits are normally being passed from the parents to the offspring. They include characteristics that determine sex and physical make up. According to natural behaviorists, it is the genes that will determine the physical trait an individual will have. These are encoded on the individuals DNA.

Therefore, behavioral traits such as sexual orientation, aggression, personality and intelligence are also encoded in the DNA. However, scientists believe that these characteristics are evolutionary. That is, they change over time depending on the physical environment adaptability. Evolutionary scientists argue that changes in genes are as a result of mutations which are caused by environmental factors. Thus, natural environment determines individual characteristics which are genetically encoded in the DNA.

Conversely, individuals possess traits that are not naturally determined. These are characteristics that are learnt rather than being born with. These are traits which largely determined by the socio-cultural environmental factors or the way the individuals are socialized within the society depending on the societal values.

These traits are learnt as an individual develops and can easily be changed by the socio-cultural environment where the individual is currently staying. These characteristics include temperament, ability to master a language and sense of humor. Behavioral theorists believe that these traits can be conditioned and altered much like the way animal behavior can be conditioned.

From the discussion it can be deduced that individuals’ traits are determined by hereditary genes and at the same time can be natured. There are those traits that cannot be changed in an individual no matter what condition the person is exposed to. These traits are inborn and embed within the individual hereditary factors.

In most cases, they constitute the physical characteristics of an individual. They also determine the physical behaviors such as walking style, physical appearance and eating habits. At the same time there are learned characteristics which are normally being conditioned by the socio-cultural values. Individuals learn these traits from the way they are socialized within the immediate social or cultural environment. In other words, such behaviors are conditioned by the cultural values encouraged by the immediate society.

In conclusion, nature vs. nurture debate still remains controversial. However, all agree that nature and nurture play a crucial role in determining an individual’s behavior. Nature is associated with heredity roles in determining the individuals characteristics where as nurture is associated with the role of socio-cultural environment in determining the individuals behavior.

If you asked your thoughts on “What influences a person’s personality more, their genetics or the way they are raised?” what would your answer be? Well, if you aren’t so sure, it is time for you to explore the long-standing debate on Nature vs Nurture.  

Nature refers to your genetic make-up, and Nurture refers to the way you were raised. Both elements play a big role in the formation of your personality! A recent study in the Human Brain Mapping Journal explored the contributions of genetics and environment to cognitive and emotional processing without favouring as predominant. 

The Nature vs Nurture debate undoubtedly remains one of the most pivotal discussions in psychology. Why wouldn’t it when every study that intended to study it differed in results? Well, it is simply a matter of perceptions. Undoubtedly, the best way to form a perception is to hear both sides! So, what are you waiting for? Read along to see which side of the argument you would bet your pretty pennies on!

Nature  

Before we dive into the argument let us understand them separately, starting with Nature. In the context of this debate, Nature refers to the genetic material of the individual, that is passed down to them by their biological parents. In other words, all the hereditary elements that contribute to one’s behaviour.  

It is often seen that if one or more parents suffer from an illness, it is very likely that the child is also susceptible to suffer from the same! For example, if a mother has suffered from prenatal depression during her pregnancy, it is likely that the child may suffer from depression at some point in their life.    

Just like illnesses, personality traits may also be hereditary. Traits like stubbornness, temper or people-pleasing tendencies may offer transfer from parent to child. However, some may argue that it has less to do with genetics and more to do with the fact that their parents and the traits that raise them are acquired through Nurture.     

What is Nativism? 

Nativism is a rather controversial ideology that led to some dramatic trouble in some parts of history! It is an ideology that believes that everything about a person, like mental and physical characteristics, is inherited and predetermined during birth.   

In the early 20th century, this ideology gave way to a racially biased eugenics movement. Lucky for us, the concept of “selective breeding”, which suggested only certain people should be allowed to reproduce, did not stick around. It was rather looked down upon after losing momentum during World War II as it was the ideology behind the Nazis’ ethnic cleansing (killing people based on their ethnicity or religious beliefs).    

Nurture  

When acquainted with a fine gentleman, women often say, “This man was raised right!” and give credit for his manners to his mother. Now that is a fine example of representing the other side of the debate: Nurture!    

Nurture refers to the upbringing of the individual and how it effects how they perceive the world around them and interact with it. A raised in the care of a joyful family is likely to be jovial. A child that was forced to raise himself on the streets may be a little more bitter but may posses’ greater survival skills in the real world. 

What is Empiricism? 

Just like the extreme belief that your Nature is completely responsible for who you are. There is also an extreme perception to oppose it that believes only your upbringing builds the person you are. Empiricism believes that at birth, the human mind is a blank slate that gradually fills up with real life experiences.  

It suggests all our behavioural differences are due to improper learning during our childhood and adolescence. It is simply the result of upbringing that governs the psychological aspect of Childhood Development. It also believes that maturation is simply a physiological aspect and has nothing to do with the development of the mind.

Nature vs Nurture  

Aren’t both perspectives absolutely fascinating? No wonder they debate on research on this subject matter has been around since the 1800’s and stayed relevant throughout. The term ‘Nature vs Nurture was coined by the psychologist Francis Galton. Galton was a Nativist that believed that intelligence was only passed down genetically.  

Galton was known for his controversial view that only intelligent people should be encouraged to marry one another and reproduce as much as possible. At the same time, non-intelligent people should be discouraged from reproducing.  

The argument of Nature vs Nurture grew subbranches over time. The most popular ones that were highly researched were personality development, child development and mental illness.  

Personality Development 

There have been many arguments about the governing factor of personality. Is it genetics or upbringing? The answer lies in the school of psychology you choose to follow.   

Behaviourists believe that your personality is simply your reactions to the environment and the world around you based on your perception and experience of it. At the same time, the biological theorist suggests that your parents inherit your personality and is a mix and match of your parents’ personality traits. 

Child Development 

In child development, there are two major theories that call the shots on each side. There is the concept of a Language Acquisition Device (LAD) by Chomsky and the social learning theory by Albert Bandura.   

According to LAD by Chomsky, children are born with an instinctive ability to learn and produce language. While Bandura’s social learning theory, suggest that people learn by observing. He proved his theory with the Bobo doll experiment, which showed that children can learn violent and aggressive behaviour by observing someone else be aggressive.   

Mental Illness Development 

The core of the debate lies in the substantial proof that both inherited traits and environmental factors play roles in the onset of mental disorders, making it impossible to dismiss either. Genetic predisposition can be a factor, as it may affect the brain’s chemical balance, leading to mental health issues. 

Similarly, environmental elements such as exposure to harmful substances and drugs can also alter brain chemistry. Moreover, upbringing plays a crucial role; for instance, a girl raised by a mother fixated on appearances may develop an eating disorder in her efforts to meet her mother’s expectations. 

In this complex interplay, the causes of mental illness could stem from genetic, environmental, or a combination of both influences. 

Therapeutic Approaches   

The effectiveness of a therapeutic method for an individual often hinges on the underlying causes of their condition, which genetic factors or life experiences can influence. Typically, the treatment strategy is tailored to the nature of the disorder and its origins. However, therapy itself is generally seen as an aspect of environmental shaping, aiming to address issues that may arise from innate predispositions or external factors.

Frequently Asked Questions

It is true that Nurture has the ability to change. Nature studies have shown that environmental factors can influence and change our genetic makeup. This phenomenon is known as Epigenetics .   

Intelligence can be both Nature and Nurture. Smart genetics may produce a smart baby, but if environmental factors are restrictive in its growth, then the child can grow up to be dull. A child born with average genetics may grow up to be a genius simply because his Nurture facilitated it or out of bare necessity

What Are Nature vs. Nurture Examples?

How is nature defined, how is nurture defined, the nature vs. nurture debate, nature vs. nurture examples, what is empiricism (extreme nurture position), contemporary views of nature vs. nurture.

Nature vs. nurture is an age-old debate about whether genetics (nature) plays a bigger role in determining a person's characteristics than lived experience and environmental factors (nurture). The term "nature vs. nature" was coined by English naturalist Charles Darwin's younger half-cousin, anthropologist Francis Galton, around 1875.

In psychology, the extreme nature position (nativism) proposes that intelligence and personality traits are inherited and determined only by genetics.

On the opposite end of the spectrum, the extreme nurture position (empiricism) asserts that the mind is a blank slate at birth; external factors like education and upbringing determine who someone becomes in adulthood and how their mind works. Both of these extreme positions have shortcomings and are antiquated.

This article explores the difference between nature and nurture. It gives nature vs. nurture examples and explains why outdated views of nativism and empiricism don't jibe with contemporary views.

In the context of nature vs. nurture, "nature" refers to genetics and heritable factors that are passed down to children from their biological parents.

Genes and hereditary factors determine many aspects of someone’s physical appearance and other individual characteristics, such as a genetically inherited predisposition for certain personality traits.

Scientists estimate that 20% to 60% percent of temperament is determined by genetics and that many (possibly thousands) of common gene variations combine to influence individual characteristics of temperament.

However, the impact of gene-environment (or nature-nurture) interactions on someone's traits is interwoven. Environmental factors also play a role in temperament by influencing gene activity. For example, in children raised in an adverse environment (such as child abuse or violence), genes that increase the risk of impulsive temperamental characteristics may be activated (turned on).

Trying to measure "nature vs. nurture" scientifically is challenging. It's impossible to know precisely where the influence of genes and environment begin or end.

How Are Inherited Traits Measured?

“Heritability”   describes the influence that genes have on human characteristics and traits. It's measured on a scale of 0.0 to 1.0. Very strong heritable traits like someone's eye color are ranked a 1.0.

Traits that have nothing to do with genetics, like speaking with a regional accent ranks a zero. Most human characteristics score between a 0.30 and 0.60 on the heritability scale, which reflects a blend of genetics (nature) and environmental (nurture) factors.

Thousands of years ago, ancient Greek philosophers like Plato believed that "innate knowledge" is present in our minds at birth. Every parent knows that babies are born with innate characteristics. Anecdotally, it may seem like a kid's "Big 5" personality traits (agreeableness, conscientiousness, extraversion, neuroticism, and openness) were predetermined before birth.

What is the "Big 5" personality traits

The Big 5 personality traits is a theory that describes the five basic dimensions of personality. It was developed in 1949 by D. W. Fiske and later expanded upon by other researchers and is used as a framework to study people's behavior.

From a "nature" perspective, the fact that every child has innate traits at birth supports Plato's philosophical ideas about innatism. However, personality isn't set in stone. Environmental "nurture" factors can change someone's predominant personality traits over time. For example, exposure to the chemical lead during childhood may alter personality.

In 2014, a meta-analysis of genetic and environmental influences on personality development across the human lifespan found that people change with age. Personality traits are relatively stable during early childhood but often change dramatically during adolescence and young adulthood.

It's impossible to know exactly how much "nurture" changes personality as people get older. In 2019, a study of how stable personality traits are from age 16 to 66 found that people's Big 5 traits are both stable and malleable (able to be molded). During the 50-year span from high school to retirement, some traits like agreeableness and conscientiousness tend to increase, while others appear to be set in stone.

Nurture refers to all of the external or environmental factors that affect human development such as how someone is raised, socioeconomic status, early childhood experiences, education, and daily habits.

Although the word "nurture" may conjure up images of babies and young children being cared for by loving parents, environmental factors and life experiences have an impact on our psychological and physical well-being across the human life span. In adulthood, "nurturing" oneself by making healthy lifestyle choices can offset certain genetic predispositions.

For example, a May 2022 study found that people with a high genetic risk of developing the brain disorder Alzheimer's disease can lower their odds of developing dementia (a group of symptoms that affect memory, thinking, and social abilities enough to affect daily life) by adopting these seven healthy habits in midlife:

• Staying active
• Healthy eating
• Losing weight
• Not smoking
• Reducing blood sugar
• Controlling cholesterol
• Maintaining healthy blood pressure

The nature vs. nurture debate centers around whether individual differences in behavioral traits and personality are caused primarily by nature or nurture. Early philosophers believed the genetic traits passed from parents to their children influence individual differences and traits. Other well-known philosophers believed the mind begins as a blank slate and that everything we are is determined by our experiences.

While early theories favored one factor over the other, experts today recognize there is a complex interaction between genetics and the environment and that both nature and nurture play a critical role in shaping who we are.

Eye color and skin pigmentation are examples of "nature" because they are present at birth and determined by inherited genes. Developmental delays due to toxins (such as exposure to lead as a child or exposure to drugs in utero) are examples of "nurture" because the environment can negatively impact learning and intelligence.

In Child Development

The nature vs. nurture debate in child development is apparent when studying language development. Nature theorists believe genetics plays a significant role in language development and that children are born with an instinctive ability that allows them to both learn and produce language.

Nurture theorists would argue that language develops by listening and imitating adults and other children.

In addition, nurture theorists believe people learn by observing the behavior of others. For example, contemporary psychologist Albert Bandura's social learning theory suggests that aggression is learned through observation and imitation.

In Psychology

In psychology, the nature vs. nurture beliefs vary depending on the branch of psychology.

• Biopsychology:  Researchers analyze how the brain, neurotransmitters, and other aspects of our biology influence our behaviors, thoughts, and feelings. emphasizing the role of nature.
• Social psychology: Researchers study how external factors such as peer pressure and social media influence behaviors, emphasizing the importance of nurture.
• Behaviorism: This theory of learning is based on the idea that our actions are shaped by our interactions with our environment.

In Personality Development

Whether nature or nurture plays a bigger role in personality development depends on different personality development theories.

• Behavioral theories: Our personality is a result of the interactions we have with our environment, such as parenting styles, cultural influences, and life experiences.
• Biological theories: Personality is mostly inherited which is demonstrated by a study in the 1990s that concluded identical twins reared apart tend to have more similar personalities than fraternal twins.
• Psychodynamic theories: Personality development involves both genetic predispositions and environmental factors and their interaction is complex.

In Mental Illness

Both nature and nurture can contribute to mental illness development.

For example, at least five mental health disorders are associated with some type of genetic component ( autism ,  attention-deficit hyperactivity disorder (ADHD) ,  bipolar disorder , major depression, and  schizophrenia ).

Other explanations for mental illness are environmental, such as:

• Being exposed to drugs or alcohol in utero 
• Witnessing a traumatic event, leading to post-traumatic stress disorder (PTSD)
• Adverse life events and chronic stress during childhood

In Mental Health Therapy

Mental health treatment can involve both nature and nurture. For example, a therapist may explore life experiences that may have contributed to mental illness development (nurture) as well as family history of mental illness (nature).

At the same time, research indicates that a person's genetic makeup may impact how their body responds to antidepressants. Taking this into consideration is important for finding the right treatment for each individual.

 What Is Nativism (Extreme Nature Position)?

Innatism emphasizes nature's role in shaping our minds and personality traits before birth. Nativism takes this one step further and proposes that all of people's mental and physical characteristics are inherited and predetermined at birth.

In its extreme form, concepts of nativism gave way to the early 20th century's racially-biased eugenics movement. Thankfully, "selective breeding," which is the idea that only certain people should reproduce in order to create chosen characteristics in offspring, and eugenics, arranged breeding, lost momentum during World War II. At that time, the Nazis' ethnic cleansing (killing people based on their ethnic or religious associations) atrocities were exposed.

Philosopher John Locke's tabula rasa theory from 1689 directly opposes the idea that we are born with innate knowledge. "Tabula rasa" means "blank slate" and implies that our minds do not have innate knowledge at birth.

Locke was an empiricist who believed that all the knowledge we gain in life comes from sensory experiences (using their senses to understand the world), education, and day-to-day encounters after being born.

Today, looking at nature vs. nature in black-and-white terms is considered a misguided dichotomy (two-part system). There are so many shades of gray where nature and nurture overlap. It's impossible to tease out how inherited traits and learned behaviors shape someone's unique characteristics or influence how their mind works.

The influences of nature and nurture in psychology are impossible to unravel. For example, imagine someone growing up in a household with an alcoholic parent who has frequent rage attacks. If that child goes on to develop a substance use disorder and has trouble with emotion regulation in adulthood, it's impossible to know precisely how much genetics (nature) or adverse childhood experiences (nurture) affected that individual's personality traits or issues with alcoholism.

Epigenetics Blurs the Line Between Nature and Nurture

"Epigenetics " means "on top of" genetics. It refers to external factors and experiences that turn genes "on" or "off." Epigenetic mechanisms alter DNA's physical structure in utero (in the womb) and across the human lifespan.

Epigenetics blurs the line between nature and nurture because it says that even after birth, our genetic material isn't set in stone; environmental factors can modify genes during one's lifetime. For example, cannabis exposure during critical windows of development can increase someone's risk of neuropsychiatric disease via epigenetic mechanisms.

Nature vs. nurture is a framework used to examine how genetics (nature) and environmental factors (nurture) influence human development and personality traits.

However, nature vs. nurture isn't a black-and-white issue; there are many shades of gray where the influence of nature and nurture overlap. It's impossible to disentangle how nature and nurture overlap; they are inextricably intertwined. In most cases, nature and nurture combine to make us who we are.

The nature vs. nurture debate in psychology concerns the relative importance of an individual’s innate qualities (nature) versus personal experiences (nurture) in determining or causing individual differences in physical and behavioral traits. While early theories favored one factor over the other, contemporary views recognize a complex interplay between genes and environment in shaping behavior and development.

Key Takeaways

• Nature is what we think of as pre-wiring and is influenced by genetic inheritance and other biological factors.
• Nurture is generally taken as the influence of external factors after conception, e.g., the product of exposure, life experiences, and learning on an individual.
• Behavioral genetics has enabled psychology to quantify the relative contribution of nature and nurture concerning specific psychological traits.
• Instead of defending extreme nativist or nurturist views, most psychological researchers are now interested in investigating how nature and nurture interact in a host of qualitatively different ways.
• For example, epigenetics is an emerging area of research that shows how environmental influences affect the expression of genes.

The nature-nurture debate is concerned with the relative contribution that both influences make to human behavior, such as personality, cognitive traits, temperament and psychopathology.

Examples of Nature vs. Nurture

Nature vs. nurture in child development.

In child development, the nature vs. nurture debate is evident in the study of language acquisition . Researchers like Chomsky (1957) argue that humans are born with an innate capacity for language (nature), known as universal grammar, suggesting that genetics play a significant role in language development.

Conversely, the behaviorist perspective, exemplified by Skinner (1957), emphasizes the role of environmental reinforcement and learning (nurture) in language acquisition.

Twin studies have provided valuable insights into this debate, demonstrating that identical twins raised apart may share linguistic similarities despite different environments, suggesting a strong genetic influence (Bouchard, 1979)

However, environmental factors, such as exposure to language-rich environments, also play a crucial role in language development, highlighting the intricate interplay between nature and nurture in child development.

Nature vs. Nurture in Personality Development

The nature vs. nurture debate in personality psychology centers on the origins of personality traits. Twin studies have shown that identical twins reared apart tend to have more similar personalities than fraternal twins, indicating a genetic component to personality (Bouchard, 1994).

However, environmental factors, such as parenting styles, cultural influences, and life experiences, also shape personality.

For example, research by Caspi et al. (2003) demonstrated that a particular gene (MAOA) can interact with childhood maltreatment to increase the risk of aggressive behavior in adulthood.

This highlights that genetic predispositions and environmental factors contribute to personality development, and their interaction is complex and multifaceted.

Nature vs. Nurture in Mental Illness Development

The nature vs. nurture debate in mental health explores the etiology of depression. Genetic studies have identified specific genes associated with an increased vulnerability to depression, indicating a genetic component (Sullivan et al., 2000).

However, environmental factors, such as adverse life events and chronic stress during childhood, also play a significant role in the development of depressive disorders (Dube et al.., 2002; Keller et al., 2007)

The diathesis-stress model posits that individuals inherit a genetic predisposition (diathesis) to a disorder, which is then activated or exacerbated by environmental stressors (Monroe & Simons, 1991).

This model illustrates how nature and nurture interact to influence mental health outcomes.

Nature vs. Nurture of Intelligence

The nature vs. nurture debate in intelligence examines the relative contributions of genetic and environmental factors to cognitive abilities.

Intelligence is highly heritable, with about 50% of variance in IQ attributed to genetic factors, based on studies of twins, adoptees, and families (Plomin & Spinath, 2004).

Heritability of intelligence increases with age, from about 20% in infancy to as high as 80% in adulthood, suggesting amplifying effects of genes over time.

However, environmental influences, such as access to quality education and stimulating environments, also significantly impact intelligence.

Shared environmental influences like family background are more influential in childhood, whereas non-shared experiences are more important later in life.

Research by Flynn (1987) showed that average IQ scores have increased over generations, suggesting that environmental improvements, known as the Flynn effect , can lead to substantial gains in cognitive abilities.

Molecular genetics provides tools to identify specific genes and understand their pathways and interactions. However, progress has been slow for complex traits like intelligence. Identified genes have small effect sizes (Plomin & Spinath, 2004).

Overall, intelligence results from complex interplay between genes and environment over development. Molecular genetics offers promise to clarify these mechanisms. The nature vs nurture debate is outdated – both play key roles.

Nativism (Extreme Nature Position)

It has long been known that certain physical characteristics are biologically determined by genetic inheritance.

Color of eyes, straight or curly hair, pigmentation of the skin, and certain diseases (such as Huntingdon’s chorea) are all a function of the genes we inherit.

These facts have led many to speculate as to whether psychological characteristics such as behavioral tendencies, personality attributes, and mental abilities are also “wired in” before we are even born.

Those who adopt an extreme hereditary position are known as nativists.  Their basic assumption is that the characteristics of the human species as a whole are a product of evolution and that individual differences are due to each person’s unique genetic code.

In general, the earlier a particular ability appears, the more likely it is to be under the influence of genetic factors. Estimates of genetic influence are called heritability.

Examples of extreme nature positions in psychology include Chomsky (1965), who proposed language is gained through the use of an innate language acquisition device. Another example of nature is Freud’s theory of aggression as being an innate drive (called Thanatos).

Characteristics and differences that are not observable at birth, but which emerge later in life, are regarded as the product of maturation. That is to say, we all have an inner “biological clock” which switches on (or off) types of behavior in a pre-programmed way.

The classic example of the way this affects our physical development are the bodily changes that occur in early adolescence at puberty.

However, nativists also argue that maturation governs the emergence of attachment in infancy , language acquisition , and even cognitive development .

Empiricism (Extreme Nurture Position)

At the other end of the spectrum are the environmentalists – also known as empiricists (not to be confused with the other empirical/scientific  approach ).

Their basic assumption is that at birth, the human mind is a tabula rasa (a blank slate) and that this is gradually “filled” as a result of experience (e.g., behaviorism ).

From this point of view, psychological characteristics and behavioral differences that emerge through infancy and childhood are the results of learning.  It is how you are brought up (nurture) that governs the psychologically significant aspects of child development and the concept of maturation applies only to the biological.

For example, Bandura’s (1977) social learning theory states that aggression is learned from the environment through observation and imitation. This is seen in his famous bobo doll experiment (Bandura, 1961).

Also, Skinner (1957) believed that language is learned from other people via behavior-shaping techniques.

Evidence for Nature

• Biological Approach
• Biology of Gender
• Medical Model

Freud (1905) stated that events in our childhood have a great influence on our adult lives, shaping our personality.

He thought that parenting is of primary importance to a child’s development , and the family as the most important feature of nurture was a common theme throughout twentieth-century psychology (which was dominated by environmentalists’ theories).

Behavioral Genetics

Researchers in the field of behavioral genetics study variation in behavior as it is affected by genes, which are the units of heredity passed down from parents to offspring.

“We now know that DNA differences are the major systematic source of psychological differences between us. Environmental effects are important but what we have learned in recent years is that they are mostly random – unsystematic and unstable – which means that we cannot do much about them.” Plomin (2018, xii)

Behavioral genetics has enabled psychology to quantify the relative contribution of nature and nurture with regard to specific psychological traits. One way to do this is to study relatives who share the same genes (nature) but a different environment (nurture). Adoption acts as a natural experiment which allows researchers to do this.

Empirical studies have consistently shown that adoptive children show greater resemblance to their biological parents, rather than their adoptive, or environmental parents (Plomin & DeFries, 1983; 1985).

Another way of studying heredity is by comparing the behavior of twins, who can either be identical (sharing the same genes) or non-identical (sharing 50% of genes). Like adoption studies, twin studies support the first rule of behavior genetics; that psychological traits are extremely heritable, about 50% on average.

The Twins in Early Development Study (TEDS) revealed correlations between twins on a range of behavioral traits, such as personality (empathy and hyperactivity) and components of reading such as phonetics (Haworth, Davis, Plomin, 2013; Oliver & Plomin, 2007; Trouton, Spinath, & Plomin, 2002).

Implications

Jenson (1969) found that the average I.Q. scores of black Americans were significantly lower than whites he went on to argue that genetic factors were mainly responsible – even going so far as to suggest that intelligence is 80% inherited.

The storm of controversy that developed around Jenson’s claims was not mainly due to logical and empirical weaknesses in his argument. It was more to do with the social and political implications that are often drawn from research that claims to demonstrate natural inequalities between social groups.

For many environmentalists, there is a barely disguised right-wing agenda behind the work of the behavioral geneticists.  In their view, part of the difference in the I.Q. scores of different ethnic groups are due to inbuilt biases in the methods of testing.

More fundamentally, they believe that differences in intellectual ability are a product of social inequalities in access to material resources and opportunities.  To put it simply children brought up in the ghetto tend to score lower on tests because they are denied the same life chances as more privileged members of society.

Now we can see why the nature-nurture debate has become such a hotly contested issue.  What begins as an attempt to understand the causes of behavioral differences often develops into a politically motivated dispute about distributive justice and power in society.

What’s more, this doesn’t only apply to the debate over I.Q.  It is equally relevant to the psychology of sex and gender , where the question of how much of the (alleged) differences in male and female behavior is due to biology and how much to culture is just as controversial.

Polygenic Inheritance

Rather than the presence or absence of single genes being the determining factor that accounts for psychological traits, behavioral genetics has demonstrated that multiple genes – often thousands, collectively contribute to specific behaviors.

Thus, psychological traits follow a polygenic mode of inheritance (as opposed to being determined by a single gene). Depression is a good example of a polygenic trait, which is thought to be influenced by around 1000 genes (Plomin, 2018).

This means a person with a lower number of these genes (under 500) would have a lower risk of experiencing depression than someone with a higher number.

The Nature of Nurture

Nurture assumes that correlations between environmental factors and psychological outcomes are caused environmentally. For example, how much parents read with their children and how well children learn to read appear to be related. Other examples include environmental stress and its effect on depression.

However, behavioral genetics argues that what look like environmental effects are to a large extent really a reflection of genetic differences (Plomin & Bergeman, 1991).

People select, modify and create environments correlated with their genetic disposition. This means that what sometimes appears to be an environmental influence (nurture) is a genetic influence (nature).

So, children that are genetically predisposed to be competent readers, will be happy to listen to their parents read them stories, and be more likely to encourage this interaction.

Interaction Effects

However, in recent years there has been a growing realization that the question of “how much” behavior is due to heredity and “how much” to the environment may itself be the wrong question.

Take intelligence as an example. Like almost all types of human behavior, it is a complex, many-sided phenomenon which reveals itself (or not!) in a great variety of ways.

The “how much” question assumes that psychological traits can all be expressed numerically and that the issue can be resolved in a quantitative manner.

Heritability statistics revealed by behavioral genetic studies have been criticized as meaningless, mainly because biologists have established that genes cannot influence development independently of environmental factors; genetic and nongenetic factors always cooperate to build traits. The reality is that nature and culture interact in a host of qualitatively different ways (Gottlieb, 2007; Johnston & Edwards, 2002).

Instead of defending extreme nativist or nurturist views, most psychological researchers are now interested in investigating how nature and nurture interact.

For example, in psychopathology , this means that both a genetic predisposition and an appropriate environmental trigger are required for a mental disorder to develop. For example, epigenetics state that environmental influences affect the expression of genes.

What is Epigenetics?

Epigenetics is the term used to describe inheritance by mechanisms other than through the DNA sequence of genes. For example, features of a person’s physical and social environment can effect which genes are switched-on, or “expressed”, rather than the DNA sequence of the genes themselves.

Stressors and memories can be passed through small RNA molecules to multiple generations of offspring in ways that meaningfully affect their behavior.

One such example is what is known as the Dutch Hunger Winter, during last year of the Second World War. What they found was that children who were in the womb during the famine experienced a life-long increase in their chances of developing various health problems compared to children conceived after the famine.

Epigenetic effects can sometimes be passed from one generation to the next, although the effects only seem to last for a few generations. There is some evidence that the effects of the Dutch Hunger Winter affected grandchildren of women who were pregnant during the famine.

Therefore, it makes more sense to say that the difference between two people’s behavior is mostly due to hereditary factors or mostly due to environmental factors.

This realization is especially important given the recent advances in genetics, such as polygenic testing.  The Human Genome Project, for example, has stimulated enormous interest in tracing types of behavior to particular strands of DNA located on specific chromosomes.

If these advances are not to be abused, then there will need to be a more general understanding of the fact that biology interacts with both the cultural context and the personal choices that people make about how they want to live their lives.

There is no neat and simple way of unraveling these qualitatively different and reciprocal influences on human behavior.

Epigenetics: Licking Rat Pups

Michael Meaney and his colleagues at McGill University in Montreal, Canada conducted the landmark epigenetic study on mother rats licking and grooming their pups.

This research found that the amount of licking and grooming received by rat pups during their early life could alter their epigenetic marks and influence their stress responses in adulthood.

Pups that received high levels of maternal care (i.e., more licking and grooming) had a reduced stress response compared to those that received low levels of maternal care.

Meaney’s work with rat maternal behavior and its epigenetic effects has provided significant insights into the understanding of early-life experiences, gene expression, and adult behavior.

It underscores the importance of the early-life environment and its long-term impacts on an individual’s mental health and stress resilience.

Epigenetics: The Agouti Mouse Study

Waterland and Jirtle’s 2003 study on the Agouti mouse is another foundational work in the field of epigenetics that demonstrated how nutritional factors during early development can result in epigenetic changes that have long-lasting effects on phenotype.

In this study, they focused on a specific gene in mice called the Agouti viable yellow (A^vy) gene. Mice with this gene can express a range of coat colors, from yellow to mottled to brown.

This variation in coat color is related to the methylation status of the A^vy gene: higher methylation is associated with the brown coat, and lower methylation with the yellow coat.

Importantly, the coat color is also associated with health outcomes, with yellow mice being more prone to obesity, diabetes, and tumorigenesis compared to brown mice.

Waterland and Jirtle set out to investigate whether maternal diet, specifically supplementation with methyl donors like folic acid, choline, betaine, and vitamin B12, during pregnancy could influence the methylation status of the A^vy gene in offspring.

Key findings from the study include:

Dietary Influence : When pregnant mice were fed a diet supplemented with methyl donors, their offspring had an increased likelihood of having the brown coat color. This indicated that the supplemented diet led to an increased methylation of the A^vy gene.

Health Outcomes : Along with the coat color change, these mice also had reduced risks of obesity and other health issues associated with the yellow phenotype.

Transgenerational Effects : The study showed that nutritional interventions could have effects that extend beyond the individual, affecting the phenotype of the offspring.

The implications of this research are profound. It highlights how maternal nutrition during critical developmental periods can have lasting effects on offspring through epigenetic modifications, potentially affecting health outcomes much later in life.

The study also offers insights into how dietary and environmental factors might contribute to disease susceptibility in humans.

What does nature refer to in the nature vs. nurture debate?

In the nature vs. nurture debate, “nature” refers to the influence of genetics, innate qualities, and biological factors on human development, behavior, and traits. It emphasizes the role of hereditary factors in shaping who we are.

What does nurture refer to in the nature vs. nurture debate?

In the nature vs. nurture debate, “nurture” refers to the influence of the environment, upbringing, experiences, and social factors on human development, behavior, and traits. It emphasizes the role of external factors in shaping who we are.

Why is it important to determine the contribution of heredity (nature) and environment (nurture) in human development?

Determining the contribution of heredity and environment in human development is crucial for understanding the complex interplay between genetic factors and environmental influences. It helps identify the relative significance of each factor, informing interventions, policies, and strategies to optimize human potential and address developmental challenges.

Essay Sample: Nature Versus Nurture

Author:  Kate Smith

This sample is a great example of the compare and contrast essay writing. It presents two points of view on what influences the development of a personality the most - genetics or environmental factors. Don't hesitate to read it to see what such a type of essay should look like when written professionally!

Nature and nurture is a hotly contested argument concerning what influences the behavior and personality attributes of individuals. Nature is entirely dependent on the genetic combination of an individual which dictates their character and appearance. On the other hand, nurture is dependent on the environmental factors that an individual gets exposed to which end up shaping his or her personality. Nature and nurture influence individuals to a certain extent because individuals get exposed to both of them in one way or the other dictating their development process.

Nature principle holds that biological characteristics of individuals get inherited from the genetic makeup in their lineage. Character traits such as height, weight, vulnerability to certain illnesses and skin complexion are inherited and determined by the genetic combination of individuals. Such biological combination is usually similar amongst individuals who are blood relatives, and for this reason, they tend to have almost a uniform genetic combination. Moreover, other behavioral, mental and personality attributes are also a reflection of our genetic makeup and usually inherited from individuals’ close blood relatives (Kong et al. 2018). Through the traits, it is easier to identify closely related individuals just by looking at their appearance and conduct.

Besides, specific characteristics do not become evident during birth, and when a person reaches a certain age, for instance, during puberty, that is when the hidden attributes begin showing up. The biological clock guides such characteristics, and when the right time comes, the physical and behavioral attributes mature and become conspicuous. Such traits get programmed in a way that for them to grow visible, they will take a certain period to develop. Moreover, they are also dependent on other biological factors within our bodies for them to manifest. However, the traits still maintain the genetic combination and the similarity of a specific lineage.

On the contrary, through nurture, an individual acquires specific attributes from the environment that surrounds them. When a child is born, for instance, its mind is black and empty. It is through its interaction with the surrounding and the people around it that will make the infant acquire some of their traits through learning, observation and aping their conducts. In other words, nurturing is dependent on the environment, experience, and learning as the individual interacts with the environment with time (Vazsonyi, Roberts, Huang & Vaughn, 2015). The way an individual was nurtured or brought up will influence their aspect of child development. Maturation will only affect biological development. The environment plays a vital role in the development process.

Similarly, the type of relationships also plays a crucial role in the nurturing, especially during child development. For instance, an infant develops an emotional attachment to its parents because of the love and affection it receives. Moreover, children who are given proper care and affection will reciprocate the same while growing up. On the contrary, infants who receive harsh treatment from their parents will develop withdrawal symptoms while growing up. Also, the infants also try and learn how and what to talk by studying the speech of those around them. The cognitive development comes from the exposer that the infant receives and conditions surrounding it.

Correspondingly, certain traits are acquired based on what an individual went through. Children who got abused or molested when growing up develop specific antisocial characteristics, for instance, being high tempered, harsh and develops particular disorders. For example, bipolar disorders manifest because an individual underwent harsh treatment which affects their psychological stability after that. Some of them become abusers and molesters in their future relationships as a way of imitating and justifying what they experienced while growing up. Imitation is a way of implementing what the individual has learned during the nurturing process by putting the lessons into practice.

Striking a Balance

However, after careful analysis, psychologists have discovered that both nature and nurture are responsible for the development of an individual. Both factors interact with each other and play a crucial role in shaping up the conduct of an individual (Lux, 2014). For example, in psychopathology, it is argued that both hereditary factors and environmental conditions contribute to the development of mental disorders in individuals. The biological combinations of people closely interact with the socio-cultural set up surrounding them. Individuals are now left to make their own choices in dictating what is suitable for them and what should be left out. Nature and nurture complement each other in shaping an individual.

Conclusively, nature and nurture are broiling discussion, and both sides have valid points to justify their stands. Nature is purely based on the fact that genetic makeup influence how an individual behaves and thinks. Similarly, the natives hold that genetic factors dictate factors such as the appearance, particular illness, and intelligence levels. On the contrary, individuals who believe in nurturing hold that environmental factors are majorly involved in the development process of individuals. Children acquire traits through learning from the people surrounding them and will try to imitate the behavior after that. However, psychologists are trying their level best to strike a balance between the two school of thoughts since both sides hold valid arguments, but both nurture and nature interact with each other during the development process. Nature and nurture cannot get treated in isolation.

The Nature vs. Nurture Debate

Genetic and Environmental Influences and How They Interact

Kendra Cherry, MS, is a psychosocial rehabilitation specialist, psychology educator, and author of the "Everything Psychology Book."

Verywell / Joshua Seong

• Definitions
• Interaction
• Contemporary Views

Nature refers to how genetics influence an individual's personality, whereas nurture refers to how their environment (including relationships and experiences) impacts their development. Whether nature or nurture plays a bigger role in personality and development is one of the oldest philosophical debates within the field of psychology .

Learn how each is defined, along with why the issue of nature vs. nurture continues to arise. We also share a few examples of when arguments on this topic typically occur, how the two factors interact with each other, and contemporary views that exist in the debate of nature vs. nurture as it stands today.

Nature and Nurture Defined

To better understand the nature vs. nurture argument, it helps to know what each of these terms means.

• Nature refers largely to our genetics . It includes the genes we are born with and other hereditary factors that can impact how our personality is formed and influence the way that we develop from childhood through adulthood.
• Nurture encompasses the environmental factors that impact who we are. This includes our early childhood experiences, the way we were raised , our social relationships, and the surrounding culture.

A few biologically determined characteristics include genetic diseases, eye color, hair color, and skin color. Other characteristics are tied to environmental influences, such as how a person behaves, which can be influenced by parenting styles and learned experiences.

For example, one child might learn through observation and reinforcement to say please and thank you. Another child might learn to behave aggressively by observing older children engage in violent behavior on the playground.

The Debate of Nature vs. Nurture

The nature vs. nurture debate centers on the contributions of genetics and environmental factors to human development. Some philosophers, such as Plato and Descartes, suggested that certain factors are inborn or occur naturally regardless of environmental influences.

Advocates of this point of view believe that all of our characteristics and behaviors are the result of evolution. They contend that genetic traits are handed down from parents to their children and influence the individual differences that make each person unique.

Other well-known thinkers, such as John Locke, believed in what is known as tabula rasa which suggests that the mind begins as a blank slate . According to this notion, everything that we are is determined by our experiences.

Behaviorism is a good example of a theory rooted in this belief as behaviorists feel that all actions and behaviors are the results of conditioning. Theorists such as John B. Watson believed that people could be trained to do and become anything, regardless of their genetic background.

People with extreme views are called nativists and empiricists. Nativists take the position that all or most behaviors and characteristics are the result of inheritance. Empiricists take the position that all or most behaviors and characteristics result from learning.

Examples of Nature vs. Nurture

One example of when the argument of nature vs. nurture arises is when a person achieves a high level of academic success . Did they do so because they are genetically predisposed to elevated levels of intelligence, or is their success a result of an enriched environment?

The argument of nature vs. nurture can also be made when it comes to why a person behaves in a certain way. If a man abuses his wife and kids, for instance, is it because he was born with violent tendencies, or is violence something he learned by observing others in his life when growing up?

Nature vs. Nurture in Psychology

Throughout the history of psychology , the debate of nature vs. nurture has continued to stir up controversy. Eugenics, for example, was a movement heavily influenced by the nativist approach.

Psychologist Francis Galton coined the terms 'nature versus nurture' and 'eugenics' and believed that intelligence resulted from genetics. Galton also felt that intelligent individuals should be encouraged to marry and have many children, while less intelligent individuals should be discouraged from reproducing.

The value placed on nature vs. nurture can even vary between the different branches of psychology , with some branches taking a more one-sided approach. In biopsychology , for example, researchers conduct studies exploring how neurotransmitters influence behavior, emphasizing the role of nature.

In social psychology , on the other hand, researchers might conduct studies looking at how external factors such as peer pressure and social media influence behaviors, stressing the importance of nurture. Behaviorism is another branch that focuses on the impact of the environment on behavior.

Nature vs. Nurture in Child Development

Some psychological theories of child development place more emphasis on nature and others focus more on nurture. An example of a nativist theory involving child development is Chomsky's concept of a language acquisition device (LAD). According to this theory, all children are born with an instinctive mental capacity that allows them to both learn and produce language.

An example of an empiricist child development theory is Albert Bandura's social learning theory . This theory says that people learn by observing the behavior of others. In his famous Bobo doll experiment , Bandura demonstrated that children could learn aggressive behaviors simply by observing another person acting aggressively.

Nature vs. Nurture in Personality Development

There is also some argument as to whether nature or nurture plays a bigger role in the development of one's personality. The answer to this question varies depending on which personality development theory you use.

According to behavioral theories, our personality is a result of the interactions we have with our environment, while biological theories suggest that personality is largely inherited. Then there are psychodynamic theories of personality that emphasize the impact of both.

Nature vs. Nurture in Mental Illness Development

One could argue that either nature or nurture contributes to mental health development. Some causes of mental illness fall on the nature side of the debate, including changes to or imbalances with chemicals in the brain. Genetics can also contribute to mental illness development, increasing one's risk of a certain disorder or disease.

Mental disorders with some type of genetic component include autism , attention-deficit hyperactivity disorder (ADHD), bipolar disorder , major depression , and schizophrenia .

Other explanations for mental illness are environmental. This includes being exposed to environmental toxins, such as drugs or alcohol, while still in utero. Certain life experiences can also influence mental illness development, such as witnessing a traumatic event, leading to the development of post-traumatic stress disorder (PTSD).

Nature vs. Nurture in Mental Health Therapy

Different types of mental health treatment can also rely more heavily on either nature or nurture in their treatment approach. One of the goals of many types of therapy is to uncover any life experiences that may have contributed to mental illness development (nurture).

However, genetics (nature) can play a role in treatment as well. For instance, research indicates that a person's genetic makeup can impact how their body responds to antidepressants. Taking this into consideration is important for getting that person the help they need.

Interaction Between Nature and Nurture

Which is stronger: nature or nurture? Many researchers consider the interaction between heredity and environment—nature with nurture as opposed to nature versus nurture—to be the most important influencing factor of all.

For example, perfect pitch is the ability to detect the pitch of a musical tone without any reference. Researchers have found that this ability tends to run in families and might be tied to a single gene. However, they've also discovered that possessing the gene is not enough as musical training during early childhood is needed for this inherited ability to manifest itself.

Height is another example of a trait influenced by an interaction between nature and nurture. A child might inherit the genes for height. However, if they grow up in a deprived environment where proper nourishment isn't received, they might never attain the height they could have had if they'd grown up in a healthier environment.

A newer field of study that aims to learn more about the interaction between genes and environment is epigenetics . Epigenetics seeks to explain how environment can impact the way in which genes are expressed.

Some characteristics are biologically determined, such as eye color, hair color, and skin color. Other things, like life expectancy and height, have a strong biological component but are also influenced by environmental factors and lifestyle.

Contemporary Views of Nature vs. Nurture

Most experts recognize that neither nature nor nurture is stronger than the other. Instead, both factors play a critical role in who we are and who we become. Not only that but nature and nurture interact with each other in important ways all throughout our lifespan.

As a result, many in this field are interested in seeing how genes modulate environmental influences and vice versa. At the same time, this debate of nature vs. nurture still rages on in some areas, such as in the origins of homosexuality and influences on intelligence .

While a few people take the extreme nativist or radical empiricist approach, the reality is that there is not a simple way to disentangle the multitude of forces that exist in personality and human development. Instead, these influences include genetic factors, environmental factors, and how each intermingles with the other.

Nature vs Nurture Examples: Genes or Environment

Categories Development

The nature versus nurture debate focuses on the question of whether genetic or environmental factors matter most in the course of human development.

What is it that makes you who you are? Some might say that it is your genes that have the greatest influence in controlling your personality and preferences. Others might say that it is your environment and the unique experiences you have had over the course of your life that have a greater role.

In this article, learn more about the nature vs. nurture debate and what research has found about the contributions of genetic and environmental factors.

What Is the Nature vs Nurture Debate?

The nature vs. nurture debate is often described as one of the big philosophical and scientific questions facing psychologists. So what exactly does this debate mean? Why is it important for understanding the human mind and behavior?  

Let’s start by learning more about each of these factors.

• Nature: This side of the debate argues that genes have the greatest influence over who we are, from the way we look to the way we behave. Genes determine physical traits such as height, eye color, hair color, and face shape, but they can also contribute to other attributes such as your personality traits and cognitive abilities.
• Nurture: This side of the debate argues that environmental variables such as upbringing, individual experiences, and other social relationships play a more important role. Your upbringing, early social interactions, school, and peers all shape who you are and how you behave.

Let’s consider an example. If a student excels at math, is it because they inherited that ability from their parents or because they work hard to learn the subject?

Nature would suggest that they do well because they are genetically inclined to do so, while nature argues that their talent stems from their upbringing and educational background.

History of Nature vs. Nurture

The debate over nature and nurture predates psychology and goes back to the days of the ancient philosophers. In philosophy, this is often referred to as the nativism versus empiricism debate. What do these terms mean and how do they relate to nature and nurture?

The nativist approach suggests that inheritance plays the greatest role in determining characteristics. Nativism proposes that people’s characteristics, both physical and mental, are innate. These are things that are passed down genetically from our ancestors. The nativist approach essentially espouses the nature side of the argument.

Noam Chomsky’s theory of language acquisition is one of the best-known examples of nativism in psychology.  Chomsky suggested that language develops as a result of an innate language acquisition device. He believed that people are able to learn language because they have an innate, hard-wired capacity for what he referred to as universal grammar.

Empiricism represents the nurture side of the debate. The empiricist approach suggests that all learning is the result of experience and environmental factors.

The philosopher John Locke took an empiricist approach and proposed a concept known as tabula rasa, which means “blank slate.” This approach that the mind is essentially that —a blank slate—and that it is through learning and experience that all knowledge, skill, and behavioral patterns are acquired.

Behaviorism is one example of an empirical approach to understanding human behavior. Behaviorists such as John B. Watson and B.F. Skinner believed that all human behavior was the result of conditioning, either classical (associative) or operant ( reinforcement and punishment ).

Watson was famously known for proclaiming that he could train anyone to be anything using the principles of conditioning, regardless of that individual’s genetics and background.

Approaches to Psychology

While few contemporary psychologists take an extreme, hard-lined empiricist or nativist approach, different branches of psychology do sometimes tend to emphasize one influence over the other.

Biological Psychology

Biological psychology, for example, tends to focus more on the nature side of the debate. This area of psychology focuses on how biological factors influence human behavior, so things such as the brain, neurons, and neurotransmitters are of greater interest than external factors.

Behavioral Psychology

Behavioral psychology tends to take the nurture side of the debate, focusing on how environmental factors and learned associations contribute to how people think and act.

Health Psychology

Health psychology is an example of an approach that tends to lie somewhere in the middle. Health psychologists are focused on understanding how both biological and environmental factors contribute and interact to affect an individual’s health.

Nature vs. Nurture Examples

Looking at examples can be helpful to understand why the nature vs nurture debate has been so crucial throughout psychology’s history. The topic is not just an important philosophical debate. It has been critical for understanding what factors influence different aspects of human behavior and has been the source of considerable controversy at times.

Consider the long debate over the factors that influence intelligence. Those on the nature side of the debate suggest that the greatest influence on IQ is inheritance. Some early thinkers such as Francis Galton believed that intelligence could largely be attributed to genetic factors.

Such views have been used to justify discriminatory social policies and attitudes. When some research suggested that some groups of people had lower IQ scores, for example, some researchers interpreted these results to suggest that these individuals scored lower as a result of genetics.

Those taking the nurture side of the debate point out that other factors, including biased test construction, racism, and systemic discrimination impacting educational access and quality, play a more important role.

Inequality, discrimination, and lack of access play a role in shaping how well people perform on intelligence tests and other assessments of educational outcomes.

Gender Differences and Education

Sex differences in school performance and attainment is another area where the debate between the contributions of nature vs nurture comes into play. Girls often perform better on verbal tests but less well on math. As they advance in school, girls also become less likely to enter STEM courses and STEM fields.

Those taking a nature perspective might suggest that girls are inherently less capable in these subjects. Nature advocates, however, would point out that social variables, including gender stereotypes and discrimination, have a greater influence.

Many researchers today believe that human behavior is influenced by both nature and nurture, and that it is often the interaction of the two variables that is even more important.

Examples of the Impact of the Nature and Nurture Debate

Few modern psychologists would take an extreme nature or nurture position. Rather than asking which one controls specific variables, researchers are more likely to wonder about the degree to which each of these forces plays a role. So what exactly are the relative contributions of nature and nurture?

According to the research, the answer is about 50/50. Researchers collected the results of nearly every twin study conducted over the last half-century. Doing this allowed them to determine which factors played a role in determining certain characteristics.

Twin studies examine similarities and differences by looking at twins who are either raised together or raised apart. This allows researchers to determine the impact of genes versus the environment.

Researchers analyzed more than 2,700 twin studies involving a whopping 14.5 million pairs of twins from 39 different countries and discovered that genes and environment share a roughly equal role in determining who we are.

Variations in personality traits and disease were determined to be 49% due to genetics and 51% due to environment.

One important thing to note is that while the research suggests a 50/50 split, the findings did reveal that genes do play a greater role in the risk of certain diseases. Bipolar disorder, for example, was found to be approximately 70% heritable.

Examples of How Nature and Nurture Interact

Today, many experts suggest that we should be more concerned with how nature and nurture interact to determine how we develop. For example, we might be genetically inclined toward a certain trait, but our experiences can determine to what degree that trait is expressed.

Height is a good example of how genes and the environment can interact to make you who you are. Even if you inherit genes for tallness, proper nourishment is important for reaching that height. Kids who come from tall families might not become tall if they do not receive proper nutrition during their childhood.

So while we know that both factors are equally important, the question we are left to ponder is just how much of a role each factor plays in the development of certain characteristics. As the research suggests, some diseases are more strongly linked to genetics than to the environment.

As researchers continue to explore how nature and nurture interact, we will continue to gain a deeper understanding of the factors that contribute to who we are.

Nature vs. Nurture

Reviewed by Psychology Today Staff

The expression “nature vs. nurture” describes the question of how much a person's characteristics are formed by either “nature” or “nurture.” “Nature” means innate biological factors (namely genetics ), while “nurture” can refer to upbringing or life experience more generally.

Traditionally, “nature vs. nurture” has been framed as a debate between those who argue for the dominance of one source of influence or the other, but contemporary experts acknowledge that both “nature” and “nurture” play a role in psychological development and interact in complex ways.

• The Meaning of Nature vs. Nurture
• The Nature-vs.-Nurture Debate
• Identifying Genetic and Environmental Factors

The wording of the phrase “nature vs. nurture” makes it seem as though human individuality— personality traits, intelligence , preferences, and other characteristics—must be based on either the genes people are born with or the environment in which they grew up. The reality, as scientists have shown, is more complicated, and both these and other factors can help account for the many ways in which individuals differ from each other.

The words “nature” and “nurture” themselves can be misleading. Today, “ genetics ” and “environment” are frequently used in their place—with one’s environment including a broader range of experiences than just the nurturing received from parents or caregivers. Further, nature and nurture (or genetics and environment) do not simply compete to influence a person, but often interact with each other; “nature and nurture” work together. Finally, individual differences do not entirely come down to a person’s genetic code or developmental environment—to some extent, they emerge due to messiness in the process of development as well.

A person’s biological nature can affect a person’s experience of the environment. For example, a person with a genetic disposition toward a particular trait, such as aggressiveness, may be more likely to have particular life experiences (including, perhaps, receiving negative reactions from parents or others). Or, a person who grows up with an inclination toward warmth and sociability may seek out and elicit more positive social responses from peers. These life experiences could, in turn, reinforce an individual’s initial tendencies. Nurture or life experience more generally may also modify the effects of nature—for example, by expanding or limiting the extent to which a naturally bright child receives encouragement, access to quality education , and opportunities for achievement.

Epigenetics—the science of modifications in how genes are expressed— illustrates the complex interplay between “nature” and “nurture.” An individual’s environment, including factors such as early-life adversity, may result in changes in the way that parts of a person’s genetic code are “read.” While these epigenetic changes do not override the important influence of genes in general, they do constitute additional ways in which that influence is filtered through “nurture” or the environment.

Theorists and researchers have long battled over whether individual traits and abilities are inborn or are instead forged by experiences after birth. The debate has had broad implications: The real or perceived sources of a person’s strengths and vulnerabilities matter for fields such as education, philosophy , psychiatry , and clinical psychology. Today’s consensus—that individual differences result from a combination of inherited and non-genetic factors—strikes a more nuanced middle path between nature- or nurture-focused extremes.

The debate about nature and nurture has roots that stretch back at least thousands of years, to Ancient Greek theorizing about the causes of personality. During the modern era, theories emphasizing the role of either learning and experience or biological nature have risen and fallen in prominence—with genetics gaining increasing acknowledgment as an important (though not exclusive) influence on individual differences in the later 20th century and beyond.

“Nature versus nurture” was used by English scientist Francis Galton. In 1874, he published the book English Men of Science: Their Nature and Nurture , arguing that inherited factors were responsible for intelligence and other characteristics.

Genetic determinism emphasizes the importance of an individual’s nature in development. It is the view that genetics is largely or totally responsible for an individual’s psychological characteristics and behavior. The term “biological determinism” is often used synonymously.

The blank slate (or “tabula rasa”) view of the mind emphasizes the importance of nurture and the environment. Notably described by English philosopher John Locke in the 1600s, it proposed that individuals are born with a mind like an unmarked chalkboard and that its contents are based on experience and learning. In the 20th century, major branches of psychology proposed a primary role for nurture and experience , rather than nature, in development, including Freudian psychoanalysis and behaviorism.

Modern scientific methods have allowed researchers to advance further in understanding the complex relationships between genetics, life experience, and psychological characteristics, including mental health conditions and personality traits. Overall, the findings of contemporary studies underscore that with some exceptions—such as rare diseases caused by mutations in a single gene—no one factor, genetic or environmental, solely determines how a characteristic develops.

Scientists use multiple approaches to estimate how important genetics are for any given trait, but one of the most influential is the twin study. While identical (or monozygotic) twins share the same genetic code, fraternal (or dizygotic) twins share about 50 percent of the same genes, like typical siblings. Scientists are able to estimate the degree to which the variation in a particular trait, like extraversion , is explained by genetics in part by analyzing how similar identical twins are on that trait, compared to fraternal twins. ( These studies do have limitations, and estimates based on one population may not closely reflect all other populations.) 

It’s hard to call either “nature” or “nurture,” genes or the environment, more important to human psychology. The impact of one set of factors or the other depends on the characteristic, with some being more strongly related to one’s genes —for instance, autism appears to be more heritable than depression . But in general, psychological traits are shaped by a balance of interacting genetic and non-genetic influences.

Both genes and environmental factors can contribute to a person developing mental illness. Research finds that a major part of the variation in the risk for psychiatric conditions such as autism spectrum disorder, anxiety disorders, depression, and schizophrenia can be attributed to genetic differences. But not all of that risk is genetic, and life experiences, such as early-life abuse or neglect, may also affect risk of mental illness (and some individuals, based on their genetics, are likely more susceptible to environmental effects than others).

Like other psychological characteristics, personality is partly heritable. Research suggests less than half of the difference between people on measures of personality traits can be attributed to genes (one recent overall estimate is 40 percent). Non-genetic factors appear to be responsible for an equal or greater portion of personality differences between individuals. Some theorize that the social roles people adopt and invest in as they mature are among the more important non-genetic factors in personality development.

Nature argument, nurture argument, interactionist perspective, criticisms and limitations of the debate.

• One of the most compelling examples of genetic influences on behavior is the study of identical twins. Identical twins share the same genes and were commonly separated at birth, yet they often display remarkable similarities in personality traits, interests, and even medical conditions.
• Genetic factors can lead to the onset of psychological disorders such as Autism and Schizophrenia.
• Evolution and natural selection have created inherited traits such as physical characteristics that enable humans to adapt to their environments.
• Early childhood experiences can heavily influence an individual’s cognitive development. Studies have shown that a nurturing environment positively contributes to intellectual development and conversely, poverty and violence negatively impact cognitive development.
• Socialization is a critical environmental factor that shapes one's personality. Cultural norms also deeply influence one's way of thinking, behavior, and personal identity.
• Environmental factors can heavily impact behavior, such as peer pressure and negative societal influences leading to adverse outcomes.
• Genetic factors and environmental factors have both been shown to interact to influence behavior, gene-environment interaction being critical scientific evidence of this.
• Epigenetics, the study of how environmental factors can activate or suppress certain genes, can have impacts on both personality and physical health.

The nature-nurture question, learning objectives.

Nature vs. Nurture Debate

Are you the way you are because you were born that way, or because of the way you were raised? Do your genetics and biology dictate your personality and behavior, or is it your environment and how you were raised? These questions are central to the age-old nature-nurture debate. In the history of psychology, no other question has caused so much controversy and offense: We are so concerned with nature–nurture because our very sense of moral character seems to depend on it. While we may admire the athletic skills of a great basketball player, we think of his height as simply a gift, a payoff in the “genetic lottery.” For the same reason, no one blames a short person for his height or someone’s congenital disability on poor decisions: To state the obvious, it’s “not their fault.” But we do praise the concert violinist (and perhaps her parents and teachers as well) for her dedication, just as we condemn cheaters, slackers, and bullies for their bad behavior. The problem is, most human characteristics aren’t usually as clear-cut as height or instrument-mastery, affirming our nature–nurture expectations strongly one way or the other. In fact, even the great violinist might have some inborn qualities—perfect pitch, or long, nimble fingers—that support and reward her hard work. And the basketball player might have eaten a diet while growing up that promoted his genetic tendency for being tall. When we think about our own qualities, they seem under our control in some respects, yet beyond our control in others. And often the traits that don’t seem to have an obvious cause are the ones that concern us the most and are far more personally significant. What about how much we drink or worry? What about our honesty, or religiosity, or sexual orientation? They all come from that uncertain zone, neither fixed by nature nor totally under our own control.

Figure 1 . Researchers have learned a great deal about the nature-nurture dynamic by working with animals. But of course many of the techniques used to study animals cannot be applied to people. Separating these two influences in human subjects is a greater research challenge. [Photo: mharrsch]

One major problem with answering nature-nurture questions about people is, how do you set up an experiment? In nonhuman animals, there are relatively straightforward experiments for tackling nature–nurture questions. Say, for example, you are interested in aggressiveness in dogs. You want to test for the more important determinant of aggression: being born to aggressive dogs or being raised by them. You could mate two aggressive dogs—angry Chihuahuas—together, and mate two nonaggressive dogs—happy beagles—together, then switch half the puppies from each litter between the different sets of parents to raise. You would then have puppies born to aggressive parents (the Chihuahuas) but being raised by nonaggressive parents (the Beagles), and vice versa, in litters that mirror each other in puppy distribution. The big questions are: Would the Chihuahua parents raise aggressive beagle puppies? Would the beagle parents raise non aggressive Chihuahua puppies? Would the puppies’ nature win out, regardless of who raised them? Or… would the result be a combination of nature and nurture? Much of the most significant nature–nurture research has been done in this way (Scott & Fuller, 1998), and animal breeders have been doing it successfully for thousands of years. In fact, it is fairly easy to breed animals for behavioral traits.

With people, however, we can’t assign babies to parents at random, or select parents with certain behavioral characteristics to mate, merely in the interest of science (though history does include horrific examples of such practices, in misguided attempts at “eugenics,” the shaping of human characteristics through intentional breeding). In typical human families, children’s biological parents raise them, so it is very difficult to know whether children act like their parents due to genetic (nature) or environmental (nurture) reasons. Nevertheless, despite our restrictions on setting up human-based experiments, we do see real-world examples of nature-nurture at work in the human sphere—though they only provide partial answers to our many questions. The science of how genes and environments work together to influence behavior is called  behavioral genetics . The easiest opportunity we have to observe this is the adoption study . When children are put up for adoption, the parents who give birth to them are no longer the parents who raise them. This setup isn’t quite the same as the experiments with dogs (children aren’t assigned to random adoptive parents in order to suit the particular interests of a scientist) but adoption still tells us some interesting things, or at least confirms some basic expectations. For instance, if the biological child of tall parents were adopted into a family of short people, do you suppose the child’s growth would be affected? What about the biological child of a Spanish-speaking family adopted at birth into an English-speaking family? What language would you expect the child to speak? And what might these outcomes tell you about the difference between height and language in terms of nature-nurture?

Figure 2 . Studies focused on twins have led to important insights about the biological origins of many personality characteristics. [Photo: ethermoon]

Another option for observing nature-nurture in humans involves twin studies . There are two types of twins: monozygotic (MZ) and dizygotic (DZ). Monozygotic twins, also called “identical” twins, result from a single zygote (fertilized egg) and have the same DNA. They are essentially clones. Dizygotic twins, also known as “fraternal” twins, develop from two zygotes and share 50% of their DNA. Fraternal twins are ordinary siblings who happen to have been born at the same time. To analyze nature–nurture using twins, we compare the similarity of MZ and DZ pairs. Sticking with the features of height and spoken language, let’s take a look at how nature and nurture apply: Identical twins, unsurprisingly, are almost perfectly similar for height. The heights of fraternal twins, however, are like any other sibling pairs: more similar to each other than to people from other families, but hardly identical. This contrast between twin types gives us a clue about the role genetics plays in determining height.

Now consider spoken language. If one identical twin speaks Spanish at home, the co-twin with whom she is raised almost certainly does too. But the same would be true for a pair of fraternal twins raised together. In terms of spoken language, fraternal twins are just as similar as identical twins, so it appears that the genetic match of identical twins doesn’t make much difference. Twin and adoption studies are two instances of a much broader class of methods for observing nature-nurture called quantitative genetics , the scientific discipline in which similarities among individuals are analyzed based on how biologically related they are. We can do these studies with siblings and half-siblings, cousins, twins who have been separated at birth and raised separately (Bouchard, Lykken, McGue, & Segal, 1990; such twins are very rare and play a smaller role than is commonly believed in the science of nature–nurture), or with entire extended families (see Plomin, DeFries, Knopik, & Neiderhiser, 2012, for a complete introduction to research methods relevant to nature–nurture).

For better or for worse, contentions about nature–nurture have intensified because quantitative genetics produces a number called a heritability coefficient , varying from 0 to 1, that is meant to provide a single measure of genetics’ influence of a trait. In a general way, a heritability coefficient measures how strongly differences among individuals are related to differences among their genes. But beware: Heritability coefficients, although simple to compute, are deceptively difficult to interpret. Nevertheless, numbers that provide simple answers to complicated questions tend to have a strong influence on the human imagination, and a great deal of time has been spent discussing whether the heritability of intelligence or personality or depression is equal to one number or another.

Figure 3 . Quantitative genetics uses statistical methods to study the effects that both heredity and environment have on test subjects. These methods have provided us with the heritability coefficient which measures how strongly differences among individuals for a trait are related to differences among their genes. [Image: EMSL]

One reason nature–nurture continues to fascinate us so much is that we live in an era of great scientific discovery in genetics, comparable to the times of Copernicus, Galileo, and Newton, with regard to astronomy and physics. Every day, it seems, new discoveries are made, new possibilities proposed. When Francis Galton first started thinking about nature–nurture in the late-19th century he was very influenced by his cousin, Charles Darwin, but genetics per se was unknown. Mendel’s famous work with peas, conducted at about the same time, went undiscovered for 20 years; quantitative genetics was developed in the 1920s; DNA was discovered by Watson and Crick in the 1950s; the human genome was completely sequenced at the turn of the 21st century; and we are now on the verge of being able to obtain the specific DNA sequence of anyone at a relatively low cost. No one knows what this new genetic knowledge will mean for the study of nature–nurture, but as we will see in the next section, answers to nature–nurture questions have turned out to be far more difficult and mysterious than anyone imagined.

What Have We Learned About Nature–Nurture?

Figure 4 . Research over the last half century has revealed how central genetics are to behavior. The more genetically related people are the more similar they are not just physically but also in terms of personality and behavior. [Photo: 藍川芥 aikawake]

It may seem surprising, but genetic influence on behavior is a relatively recent discovery. In the middle of the 20th century, psychology was dominated by the doctrine of behaviorism, which held that behavior could only be explained in terms of environmental factors. Psychiatry concentrated on psychoanalysis, which probed for roots of behavior in individuals’ early life-histories. The truth is, neither behaviorism nor psychoanalysis is incompatible with genetic influences on behavior, and neither Freud nor Skinner was naive about the importance of organic processes in behavior. Nevertheless, in their day it was widely thought that children’s personalities were shaped entirely by imitating their parents’ behavior, and that schizophrenia was caused by certain kinds of “pathological mothering.”

Whatever the outcome of our broader discussion of nature–nurture, the basic fact that the best predictors of an adopted child’s personality or mental health are found in the biological parents they have never met, rather than in the adoptive parents who raised them, presents a significant challenge to purely environmental explanations of personality or psychopathology. The message is clear: You can’t leave genes out of the equation. But keep in mind, no behavioral traits are completely inherited, so you can’t leave the environment out altogether, either. Trying to untangle the various ways nature-nurture influences human behavior can be messy, and often common-sense notions can get in the way of good science. One very significant contribution of behavioral genetics that has changed psychology for good can be very helpful to keep in mind: When your subjects are biologically-related, no matter how clearly a situation may seem to point to environmental influence, it is never safe to interpret a behavior as wholly the result of nurture without further evidence. For example, when presented with data showing that children whose mothers read to them often are likely to have better reading scores in third grade, it is tempting to conclude that reading to your kids out loud is important to success in school; this may well be true, but the study as described is inconclusive, because there are genetic as well as  environmental pathways between the parenting practices of mothers and the abilities of their children. This is a case where “correlation does not imply causation,” as they say. To establish that reading aloud causes success, a scientist can either study the problem in adoptive families (in which the genetic pathway is absent) or by finding a way to randomly assign children to oral reading conditions.

Think It Over

• Is your personality more like one of your parents than the other? If you have a sibling, is their personality like yours? In your family, how did these similarities and differences develop? What do you think caused them?
• Can you think of a human characteristic for which genetic differences would play almost no role? Defend your choice.
• Do you think the time will come when we will be able to predict almost everything about someone by examining their DNA on the day they are born?
• Identical twins are more similar than fraternal twins for the trait of aggressiveness, as well as for criminal behavior. Do these facts have implications for the courtroom? If it can be shown that a violent criminal had violent parents, should it make a difference in culpability or sentencing?

adoption study : a behavior genetic research method that involves comparison of adopted children to their adoptive and biological parents behavioral genetics : the empirical science of how genes and environments combine to generate behavior heritability coefficient : an easily misinterpreted statistical construct that purports to measure the role of genetics in the explanation of differences among individuals quantitative genetics : scientific and mathematical methods for inferring genetic and environmental processes based on the degree of genetic and environmental similarity among organisms twin studies : a behavior genetic research method that involves comparison of the similarity of identical (monozygotic; MZ) and fraternal (dizygotic; DZ) twins

Sample critical essay on nature vs. nurture.

Select network

There has long been a debate about whether nature or nurture matters more in determining the traits an individual will have. In other words, do genetics or environment play a more formative role in the development of one’s personality? Nature says that our traits are influenced by genetic inheritance and similar biological factors while nurture is meant as the influence of environmental factors after conception.

We know that physical characteristics like eye color, hair color, and height can be attributed to specific genes within our DNA. But what about emotional or behavioral traits?  This sample biological essay from the essay writing services at Ultius examines the question that while some behavioral traits can be traced to certain genes, does our environment play a role in activating those genes?

Our genetic makeup

Science tells us that certain traits are most definitely attributed to genetic causes. Our eye color, skin pigmentation, and certain diseases like Tay-Sachs or Huntingdon’s chorea are all direct results of the genes we inherit from our parents. Other traits to which we can be genetically predisposed include weight, height, life expectancy, hair loss, and vulnerability to certain illnesses (McLeod 2007). Because these characteristics can be definitively connected to our biology, many speculate on whether or not genetic factors can contribute to behavioral tendencies, mental abilities, and personality traits .

Nativists, those who believe that every characteristic we have is determined only by nature, assume that the characteristics of the human species as a whole are simply a product of evolution and that the things that make us unique are a result of our own specific genetic code. They believe that the characteristics that are not observable at birth, such as personality traits, emerge later as the product of maturation.

We each have a biological clock inside us that turns certain behaviors on and off in a way that is preprogrammed from birth. An example of this would be the way our bodies change during puberty. Nativists also believe that:

“maturation governs the emergence of attachment in infancy, language acquisition, and even cognitive development as a whole” (McLeod 2007).

Bowlby’s theory of attachment views the bond between the mother and child as being an innate process that aids in our survival as a species. Likewise, Chomsky believed that language is learned through the use of an innate language acquisition device that all humans are born with (McLeod 2007). In addition, Freud speculated that traits like aggression are engrained in our DNA. 

Fraternal twins as evidence of nature over nurture

Similarly, it is often debated whether or not criminal activity can be linked to a genetic disposition. One of the biggest pieces of supporting evidence for the nature over nurture is the fact that fraternal twins exhibit similar characteristics even when they are raised apart. Often times, these twins will share behavioral traits as if they were raised together in the same place. Mental health is undoubtedly affected by our biological dispositions.

For example, bipolar is approximately five times as likely to develop when there is a family history of the condition (“Nature vs. Nurture Debate”). There are similar statistics available for a wide number of mental health conditions . Researchers also tend to place more emphasis on nature when it comes to addiction. Alcoholism, for example, can recur in families and it has been found that certain genes may influence the development of alcoholism and the way alcohol effects the body.

Alternatively, to nativists, empiricists believe that the human mind is a blank slate at birth and any characteristics we develop are a result of our experiences and environment. With point of view speculates that psychological characteristics and our behavioral tendencies are things we learned during our development. While the concept of maturation applies to the biological development we experience, any psychological growth is a result of the way we are brought up.

Attachment of infants as evidence of nurturing

An example of this would be the way infants form attachment. The formation of attachment is a direct result of the love and attention a child receives. If they are not given love and attention, the attachment will not develop. Similarly, we learn language by mirroring the speech we hear from others.

Our cognitive development is dependent on the environment and civilization in which we are reared (“Nature vs. Nurture”). Bandura’s social learning theory states that aggression is a characteristic that we learn through observation and imitation. In addition, Skinner believed that language is something individuals learn from others via behavioral shaping techniques.

Watson's ideas on environmental learning

John Watson, one of the most well-known psychologists to propose environmental learning as the dominating factor in the nature versus nurture debate, feels that our behavioral traits are purely a result of our surroundings and experiences. He felt that he could condition a new behavior in a child or alter an already existing behavior that is considered to be unfavorable (Sincero 2016).

Watson believed that he could randomly choose any baby out of a group of twelve infants and raise the child to become any type of specialist he chose. He stated that he could train any child to be anything, regardless of the individual’s talents, potentialities, and social groups.

Benefits of nurturing on mental health

Just like nature, nurture affects our mental health, as well. While someone may have a genetic disposition for one condition or another, there still needs to be an environmental trigger for that condition to develop. If there is a genetic indication that a mental condition may develop, the individual can be ‘nurtured’ in a way that can prevent the condition from developing or lessen its severity.

A neuroscientist named James Fallon discovered that he possessed the brain of a psychopath and believed that being raised in a loving and nurturing environment helped ensure that he never fully developed enough sociopathic traits for them to affect his success (“Nature vs. Nurture Debate”).

The foundations of addiction

In a similar way, the basis for addiction is not entirely determined by genetics. Certain environmental aspects, such as the habits of our friends, partners, and parents, can contribute significantly to the development of addiction. A genetic predisposition to alcoholism becomes entirely more significant when the individual in question is frequently exposed to alcohol abuse and comes to view the harmful behavior as normal.

A study conducted at the University of Liverpool found that a family history of mental health conditions was only the second strongest indicator that a mental condition would develop (“Nature vs. Nurture Debate”). The strongest predictor was life events and experiences that contributed to the development of the mental condition, such as abuse, bullying, or childhood trauma.

Meeting in the middle

Today, most people agree that our characteristics are a result of a combination of both nature and nurture. There is enough support for both sides to completely count either side out. For example, if one twin develops schizophrenia gene , the other twin has only a fifty percent chance of also developing the same condition (“Nature vs. Nurture Debate”). Clearly, both nature and nurture can affect the development of certain disorders.

The question then shifted from ‘which one’ to ‘how much?’ We know that both play a role, but which force is more important? Francis Galton was the first to pose this question during the late nineteenth century. A relative of Charles Darwin, he felt that intellectual ability was mostly attributed to genetics and that the tendency for genius to be a familial trait was the result of natural superiority (McLeod 2007).

Arthur Jenson on intelligence testing

Many others have agreed throughout history, which has spurred an influx of intelligence testing; in particular, on separated twins and adopted children. Arthur Jenson is an American psychologist who is a modern proponent of nature over nurture. Jenson cites average IQ scores in which black Americans scored significantly lower than white participants and suggested that as much as eighty percent of intelligence is inherited (McLeod 2007).

Not surprisingly, controversy developed surrounding Jenson’s claims due to the logical weakness of his argument. It was widely agreed that his study was tainted by social and political implications that are often drawn from various studies that claim to represent natural inequalities between race and other social groups. Differences in IQ scores between various ethnic groups can be explained by biases in testing methods and social inequalities in access to resources and opportunities (McLeod 2007). Similarly, it is hotly debated whether or not alleged intelligence difference in male versus female results is a consequence of biology or culture.

The importance of both nature and nurture

Now, however, the scientific world has come to understand that trying to place a numerical value on nature and nurture to judge which is more important is not really the right approach (Davies 2001). Intelligence, for example, is a complex human characteristic that can exhibit itself in a wide variety of ways from genius to basic common sense .

By attempting to place quantitative values on the separate factors, we fail to focus on the fact that biology and environment interact in a host of important and intricate ways (Ridley 2003). Today, most people agree that neither biology nor environment act independently of one another. Both are necessary for any characteristic to manifest. Because they are dependent on each other and interact in such a complex manner, it is illogical to attempt to think of them separately. 

How nature and nurture combine in the individual

Rather than defending nativists or empiricists, most psychologists are now more interested in researching the ways in which nature and nurture interact with each other to develop characteristics and traits. In psychotherapy, this means that not only does there need to be a genetic disposition required for mental disorders to develop, but there also needs to be an environmental trigger, as well (Feller 2015).

The recognition of this important relationship is especially important given the genetic advancements made during the twenty-first century. The Human Genome Project and advent of bioengineering sparked wide interest in tracing types of behavior to particular strands of DNA found on certain chromosomes (McLeod 2007). Scientists expect to soon find specific genes that are linked to criminality, alcoholism, and other characteristics.

Conclusion 

Psychologists have been debating the influence of nature versus nurture over human characteristics for a very long time. After the scientific world came to recognize that biology and environment both play a role, the emphasis shifted to determining which was more important. Now though, as we have come to truly understand the complexity of the relationship between our genetic dispositions and environmental triggers, we no longer focus on one versus the other, but rather the way they interact with and affect each other.

While it is certainly helpful in the development of certain conditions for there to be a genetic disposition, there almost always needs to be an environmental trigger that causes the characteristic to manifest in an individual. This is only a small part of this complex discussion and an example of what you can expect when you buy a critical essay from Ultius.

Nature Vs Nurture Essay for Students and Children

500+ words essay on nature vs nurture.

The topic of nature vs nurture is always a great topic of debate among people. There are great men who did work hard to achieve great heights . But still, they are some people who didn’t work that hard yet still managed to be successful.

In other words, it is a debate between hard work and talent. In the grooming of a person, the nurturing is essential. However, still, there are some individuals who were never born in a great environment . Yet by their sense of knowledge and intellectualism created a special place in the hearts of people.

Nature has given us many things in life and one of them is talents. Either we are born as the only individual in our family or it is in our genes. Furthermore, nature plays a vital role in deciding the future of a child. Many singers in this era are born with beautiful voices. They did not need any nurturing. Their talent took them to heights they couldn’t even imagine.

For instance, some of the great legends like Lata Mangeshkar, Asha Bhosle, Kishor Kumar had soulful voices. Also, they were the ones who sang from their childhood days. They started their careers and became successful at a very early age. Moreover, they did not get much teaching but still are the legends of all time.

Apart from singing, there are other talents that nature has given us. Various scientists like Albert Einstein , Isaac Newton , Galileo Galilei, started their work in their teenage years. They had amazing intellectualism, because of which they got recognition in their entire world. Furthermore, these scientists did not get any mentoring. They did everything on their own. Because they had extraordinary intelligence and ambition in life.

On the other hand, the nurturing of a person is important. Because hard work beats talent. With proper mentoring and practice, a person can achieve success in life. If a person has an environment in which everybody is in the same profession and are successful in it.

Then there is a great chance that the person will land up in the same profession and will achieve heights. Because in that environment he will get proper nurturing.

Furthermore, he will also be able to perform better over the years. “ Hard work always pays off ”. This idiom is always true and nobody can deny that. If a person has true dedication then it can beat talent. Various singers, dancers, musicians, businessmen, entrepreneurs did work really hard for years.

And because of that, they got recognition in the entire world. In these categories, musicians are who achieved heights only with their hard work and constant practice.

It is true that there are no shortcuts to success. Various known legends like Bob Dylon. Lou Reed, Elvis Persley, Michael Jackson worked hard throughout their lives. As a result, they were some of the great personalities in the entire world.

Q1. What is the meaning of nurture?

A1. Nurture means the way a person grooms himself. This is done in order to achieve success. Nurturing is essential in a person’s life because it can be a way a person can cross the barrier and do something great. Moreover nurture also means the mentoring and care a person is getting in an environment.

Q2. What is the difference between Nature and Nurture?

A2. The main difference between nature and nurture is, nature is the talent a person inherits from his parents or is God gifted. While nurturing is hard work and mentoring of a person in a particular field. So that he may excel in that field.

Nature versus Nurture Debate in Psychology by Hunter Honeycutt LAST REVIEWED: 12 January 2023 LAST MODIFIED: 12 January 2023 DOI: 10.1093/obo/9780199828340-0305

The nature-nurture dichotomy is a long-standing and pervasive framework for thinking about the causal influences believed to be operating during individual development. In this dichotomy, nature refers to factors (e.g., genes, genetic programs, and/or biological blueprints) or forces (e.g., heredity and/or maturation) inherent to the individual that predetermine the development of form and function. Nurture generally refers to all the remaining, typically “external,” causal factors (e.g., physical and social conditions) and processes (e.g., learning and experience) that influence development. The nature versus nurture debate in psychology deals with disagreements about the extent to which the development of traits in humans and animals reflects the relative influence of nature and nurture. It is commonly stated that psychologists have moved on from asking whether traits (or variation in traits) develop from nature or nurture, to recognize instead that both nature and nurture work together or “interact” to produce outcomes, although exactly how to view the interaction is a matter of much debate. While acknowledging the interaction of nature and nurture, one’s theoretical models and research focus might emphasize the prominence of one over the other. Thus, nativists focus more on the importance of innate factors or forces operating on development, whereas empiricists focus more on experiential or environmental factors. However, not everyone finds value in thinking about development in terms of nature and nurture. By the middle of the twentieth century, some psychologists, biologists, and philosophers began to view nature-nurture as a conceptually deficient and biologically implausible dichotomy that oversimplifies the dynamics of behavior and development. Such people espouse some variant of “developmental systems theory” and seek to eliminate or otherwise fuse the nature-nurture division.

The works in this section are mostly trade books that provide general introductions to the nature-nurture debate across a variety of topical areas in psychology, all of which would be suitable for use in classes with undergraduate students at all levels. Goldhaber 2012 contrasts four popular perspectives on the nature-nurture issue and would be a good place to start for anyone unfamiliar with the nature-nurture debate in psychology. Nativist perspectives are represented by Pinker 2002 , Plomin 2018 , and Vallortigara 2021 . An empiricist-leaning position on behavior development is put forth in Schneider 2012 . Developmental systems theory is promoted in Blumberg 2005 and Moore 2002 . Two edited books are included and both are better suited for advanced undergraduate- or graduate-level students. The first edited book, Coll, et al. 2013 , focuses on the nature-nurture issue across a range of topics and perspectives in psychology. The other, Mayes and Lewis 2012 , presents empiricist (or environmentalist) perspectives on child development.

Bateson, P. 2017. Behaviour, development and evolution . Cambridge, UK: OpenBook Publishers.

DOI: 10.11647/OBP.0097

Written by a distinguished ethologist who draws extensively from his work on animal behavior, this book argues that the nature-nurture division is neither valid nor helpful in capturing the complex system of factors that influence behavioral development. Topics include imprinting and attachment, parent-offspring relations, the influence of early-life experiences on later-life outcomes, problems with genetic determinism, and the role of behavior in evolutionary change.

Blumberg, M. S. 2005. Basic instinct: The genesis of novel behavior . New York: Thunder’s Mouth Press.

Consistent with developmental systems theory, Blumberg presents an overview of the conceptual and empirical limitations of nativism in explanations of behavioral and neural development in animals and cognitive development in humans.

Coll, C. G., E. L. Bearer, and R. M. Lerner, eds. 2013. Nature-nurture: The complex interplay of genetic and environmental influences on human behavior and development . New York: Psychology Press.

The contents of this edited volume are almost entirely original works with commentary that span multiple disciplines (psychology, biology, economics, philosophy) and multiple perspectives (behavioral genetics and developmental systems theory) on the nature-nurture issue.

Goldhaber, D. 2012. The nature-nurture debates: Bridging the gap . Cambridge, UK: Cambridge Univ. Press.

DOI: 10.1017/CBO9781139022583

Goldhaber reviews four major perspectives (behavior genetics, environmentalism, evolutionary psychology, and developmental systems theory) on the nature-nurture issue. He argues we should reject reductionist views based on either genetic determinism or environmental determinism in favor of more holistic, interactionist approaches.

Mayes, L. C., and M. Lewis, eds. 2012. The Cambridge handbook of environment in human development . Cambridge, UK: Cambridge Univ. Press.

This handbook explores a wide variety of ways in which the environment influences child development. Chapters cover conceptual frameworks and methodological issues in thinking about and studying environmental influences as well reviewing ways in which environmental contexts and systems influence specific aspects of child development.

Moore, D. S. 2002. The dependent gene: The fallacy of nature vs. nurture . New York: Henry Holt.

This book provides an introduction to the developmental systems theory take on the nature-nurture issue particularly as it relates to genetic determinism, heritability and heredity.

Pinker, S. 2002. The blank slate: The modern denial of human nature . New York: Viking.

In this best-selling book, Pinker draws on evidence from behavioral genetics, evolutionary psychology, and cognitive psychology to argue for a nativist position concerning human nature.

Plomin, R. 2018. Blueprint: How DNA makes us who we are . Cambridge, MA: MIT Press.

Plomin reviews traditional and more modern evidence from behavioral genetics to argue that genes are the primary factor in bringing about psychological differences between people. Moreover, he argues that many “environmental” factors operating on development are themselves strongly influenced by genetic differences.

Schneider, S. M. 2012. The science of consequences: How they affect genes, change the brain, and impact our world . Amherst, NY: Prometheus Books.

Schneider presents a view grounded in behavior analysis to argue for the critical role that the consequences of genetic activity, neural activity, and behavioral activity play in individual development. While emphasizing environmental (or experiential) factors influencing development, this book also highlights the systemic and interactive nature of developmental systems across multiple levels of analysis.

Vallortigara, G. 2021. Born knowing: Imprinting and the origins of knowledge . Cambridge, MA: MIT Press.

DOI: 10.7551/mitpress/14091.001.0001

Drawing upon research in comparative cognition and comparative neuroscience, much of it his own, Vallortigara argues that animals, including humans, enter the world with a set of unlearned, innate or instinctive behaviors and neural circuits that bias or predispose subsequent learning and development.

Nature versus nurture—on the origins of a specious argument

Robert o wright.

Department of Environmental Medicine and Public Health, Icahn School of Medicine at Mount Sinai, New York, NY, USA

The concept of heritability parses out genetic and environmental causes of diseases and does not fit the underlying biology of complex diseases that arise from interactions among genetics and environment. Exposomics places environment on a similar scale as genomics and allows for more modern research approaches that estimate time-varying genome by exposome interactions. By addressing the biological underpinnings of disease comprehensively, we will find the “missing heritability” which is not solely based on genetic variation but is instead driven by time, life stage, and geographic variability in our exposome as it interacts with our genome.

Heritability studies are among the more common projects cited in the lay press. In most cases, the article will say something similar to “New Research shows that Disease ‘X’ is Genetic.” The lay press’s focus on heritability has contributed to a broad genocentric view of initiatives such as precision medicine. 1 , 2 Heritability studies are typically performed in twins, both identical and fraternal. Because identical twins have the exact same genetic variation, and fraternal twins share an average of 50% of their genetic variation, the rates of a disease in both types of twins can be compared with the primary goal of estimating the genetic contribution. In theory, the goal could be to estimate the environmental contribution, but if that has been emphasized, it is the exception, not the rule. Of course, a lot of assumptions have to be made about how to divide causation between genetics and environment, since more than just genes are shared between twins. All twins share an identical environment in pregnancy and even after birth they share very similar environments. The division of what arises from shared environment versus shared genetics is subjective at best. Regardless, these studies divide disease causation to a percentage due to genetics and a percentage due to environment. Although there have been many calls to include environment as a critical, modifiable contributor to preventing disease, the ‘elephant in the room’ of personalized medicine is that the field has grown ever more genocentric over time. 2 With the advent of exposomics, the field is beginning to shift toward an understanding that environment matters critically in all diseases as well.

Because they are simple to understand and explain, heritability studies make good soundbites. For this reason, we should consider the impact they have on the general public. If a newspaper article states that a study showed that asthma is 82% genetic 3 —most people would think this meant that out of every 100 people with asthma, 82 of them got it because of their genes and 18 got it because of environment. But it doesn’t mean that. In fact, there is no known “gene” or “cluster of genes” that causes asthma. Genetic variants provide increased risk, not cause. We also know that environment (pollen, animal dander, infections, air pollution, stress, and many, many others) plays a role as they all can trigger asthma attacks and most have been associated with its onset. This heritability study could make the public think that environment is not as important to asthma as genetics. Yet all asthma interventions, drugs, inhalers, allergen mitigation, etc. are designed to address environment. Gene therapy is not around the corner for asthma, nor is it likely to ever be.

Simplicity can be good for communicating scientific information, but oversimplification can be damaging. Biology is far too complicated to be boiled down to two percentages attributing cause to genes versus environment. Even more importantly, the real problem with the concept of heritability is that it assumes that our genes and our environment don’t work together. That’s the major flawed assumption—that they can be divided as causes. Focusing on heritability prevents us from moving science forward to understand what is really happening. Furthermore, we not only assume they are independent, we also routinely use language that suggests they work against each other (ie, Nature versus Nurture), and by doing so we create false impressions. Genes and environment always work hand in hand . How can anyone ever decide how much of a percentage to give out to each? It’s like deciding what percent of the Beatles success we should give to Ringo.

So how did we get here? The origin of this problem comes from that simple phrase we all learned in high school—‘nature versus nurture’. We use it to convey the idea that genetics plays a role in our health and so does environment. In theory that seems like a good communication strategy, except our language conveys a different message. The “versus” in Nature versus Nurture implies a contest—like a prize fight. Nature versus Nurture was first coined in the mid-1800s by an English statistician—Francis Galton (interestingly, he was Charles Darwin’s cousin) while writing about the influence of genetics and environment on intelligence. His 19th century concept is badly outdated. We know environment is key to intelligence and to test taking ability. In fact, the Flynn effect refers to the increase in population intelligence quotient (IQ) scores observed throughout the 20th century of about three IQ points per decade. Rapid changes like that cannot be explained by genetics. 4 “Nature versus nurture” has been kept alive far too long and continues to make us pick a side—genetics or environment.

In fact, Galton was positing that genes create or select an environment of wealth and privilege which is counter to Darwin’s theory of Natural Selection. While most people think of natural selection as a genetic theory, it is actually a theory about how genes and environment interact. Under natural selection, genes are selected if they provide an advantage for reproduction in a given environment. If we don’t reproduce, our genes “die” so to speak, as they cease to exist in subsequent generations. If our environment were ever to change to be harsh enough to kill a large number of us at an early age, perhaps due to famine, some genes might provide survival advantages. Maybe your genes would allow for a higher absorption of food during a famine, so you might survive longer than others, but famine hasn’t happened in America or Britain for a very long time and those genetic traits have no added value outside of famine. Galton was an aristocrat who believed that his genes selected his environment of wealth and education and that his progeny’s genes would do the same. Natural selection actually posits the opposite . Environment selects for genes that better survive in harsh conditions. Under natural selection, being poor and oppressed should select more adaptive, higher functioning traits over time than genes passed down multiple generations in a family that is rich through inherited wealth. In fact, many environmental factors, such as the great wealth of Galton’s family, are also inherited. The impact of his inherited wealth cannot be easily disentangled from the genetic variants that by chance came with it. His wealth made it seem to him like his genes functioned more highly than those in people without wealth, but his genes were just there for the ride, and were no different or better than working class people. Inherited wealth will make anyone’s inherited genes look better than they actually are.

We can even illustrate how environment and genes always interact, by using genetic diseases. Phenylketonuria or PKU—for short. It is a genetic disorder that arises from a mutation in the phenylalanine hydroxylase gene. If a person has two copies of the mutated gene they cannot properly metabolize phenylalanine, an amino acid, after it is ingested. Toxic forms of metabolism accumulate and can damage the developing brain. Untreated, PKU can lead to intellectual disability, seizures, and behavioral problems. However, the disease won’t occur if a newborn baby is given an environmental intervention—a special low phenylalanine formula. The same is true for any genetic disease, all genes have something in the environment that acts as a substrate. Sometimes that substrate is so common or essential that it cannot be easily regulated or avoided and penetrance is high (cystic fibrosis and electrolytes) or sometimes it is so variable in different environments that penetrance is highly variable (hemochromatosis and iron). More recent publications have stressed that heritability is not deterministic and is expected to vary across populations as the prevalence of genetic variants and environment factors nearly always vary across different populations and the genetic and environmental variance is tied to their prevalence. 5

What would happen if we studied the heritability of PKU using twins. While some may get missed during screening, the majority of fraternal twins with the PKU genotype would be treated, many of the identical twins would be too. This means the heritability of a disease we label as 100% genetic would be <100% if we did a twin study of PKU and developmental delays. That alone tells us that heritability is not dependent only on genetics. Ken Rothman, a famous epidemiologist, once wrote “all diseases are 100% genetic and 100% environmental.” 6 In other words, they are not fighting, they are working together and always do. While PKU has a relatively uncomplicated biological cause, complex diseases have many genetic and environmental risk factors, with the environmental factors being potentially time varying. Attempts at estimating shared environment in early life have been made in Twin Studies, which is a welcomed development. 7 However, we have not yet invested as a society in developing the technologies needed to measure the exposome on a scale similar to the genome, although many of the geospatial, instrumentation, and analytical infrastructure exists. Until we commit the resources to measure the exposome, we will have continue to fall back on dichotomous estimates of genetic and environmental contributors to disease. We need to measure the “E” in the ubiquitous “G by E” interactions that drive health and disease, not measuring G by E interactions is the reason genetics has not made our society healthier. We need to understand the environmental factors our genes interact with, otherwise nothing will ever change.

So the next time a study breaks down a disease into percentages of genetic and environmental causes, we should ask—can genes ever operate by themselves? Or do they operate by interacting with the world in which we live? There is no example of even one gene that doesn’t ultimately operate by interacting with something that we ingested, inhaled, or acquired then synthesized in some way inside our body. Every gene needs a substrate for the protein it encodes. That substrate comes from our environment—genes need environment to operate. If we expand our measures of the environment to the exposome, just as genetics expanded to genomics, we can begin understand the complex time-varying ways the genome and exposome interact.

Maybe this concept was best expressed by the neuropsychologist Donald Hebb, who researched language acquisition and learning in children. When he was asked ‘Which contributes more to personality—nature or nurture?’ he answered ‘Which contributes more to the area of a rectangle, its length or its width 8 ?’

Man City have declared all-out war on Premier League – and their rivals

Abu Dhabi-owned club are suing top flight and want to destroy rules they signed up to – putting competitive nature of league in danger

The Premier League clubs who break bread with their Manchester City counterparts at their annual general meeting in Yorkshire this week at least know now what they are up against: a complete demolition of the financial controls that protect the league’s competitiveness.

If there were any doubts then they were dispelled in the Premier League’s outline of its defence against City’s legal case circulated to clubs on Tuesday. English football is in a battle for survival against a club owned by an Abu Dhabi royal trying to spend everyone else into oblivion. City wish to blow up the rules that determine a fair value for commercial deals without which the league turns into an unfettered spending frenzy for those with unlimited wealth.

The description of the democracy of the Premier League’s super majority of 14, in which Bournemouth have the same voting power as Liverpool, as a “tyranny of the majority” was the document’s most telling phrasing. Drafted by a lawyer on behalf of City Football Group’s [CFG] principal owner Sheikh Mansour, a man born into a family of dynastic Emirati rulers, it at least gave an insight into the mindset behind it all.

Without serious controls on the value of commercial deals earned by clubs from entities in the same state from which that club’s owner originates – associated-party transactions (APTs) as they are known – there can be no financial fair play. It is extraordinary that this still requires saying, and yet here we are, with one club trying to collapse the whole structure.

Since the Abu Dhabi-based 2008 takeover City’s commercial revenue has soared from €26 million in the last season before the sale, to €399 million in the most recent Deloitte audit. That figure for commercial income was just short of the €403 million earned by Real Madrid for the same 2022-2023 season.

Without oversight of what Abu Dhabi entities like Etihad and e&, formerly Etisalat Group, pay to City; or Sela or others from Saudi Arabia pay to Newcastle United, there can be no profit and sustainability rules (PSR). The same PSR that have led to points deductions for Everton and Nottingham Forest, with more likely for Leicester City, are simply washed away. Neither can there be squad costs, the PSR successor, which is introduced in its place for 2025-2026, and will limit spending to a percentage of revenue.

Without robust APT rules, these are meaningless. A limit to spend 85 per cent of revenue on players costs becomes 85 per cent of whatever a club like City wants it to be. It would put no limit on their pursuit of the best players. It would put no limit on them signing players simply so that others could not have them.

Football works on a consensus that the primacy of the competition has to take priority. The outcome in six of the past seven Premier League seasons has been a City title, but at least those have been close run. On any given match day there are jeopardy and surprise defeats. Without jeopardy there is no interest, and without interest there are not the broadcast deals upon which the Premier League has built its power.

‘They know dragging the Premier League to court does immeasurable damage’

The rise and fall of each dynasty – be it Liverpool, Manchester United or City – is what makes the game so compelling and without which it would just be a monotony of the same hegemony stretching out endlessly into the future.

The apologists’ argument is that it is all a conspiracy to keep the established elite in situ. If one was to assume that was the grand plan then one would have to say its execution has been far from perfect. City are the most dominant side in the history of English league football. All the rest of the game is asking is that they comply with the rules that they signed up to .

Project Big Picture and the European Super League have weakened the Premier League. The long delays in bringing the 115 charges against City for historical breaches of rules, including those over APTs, seems to have emboldened the vast legal resources at City’s disposal . Now they are on the attack. They wish to dismantle the dynamic that has made the Premier League less iniquitous and more successful than European rivals. Part of which is an acknowledgement that while some clubs are richer than others, none should be allowed unlimited owner-equity investment.

Those at City know this is fundamental to the success of the league, because many of them worked at the club – or at other clubs – before 2008. They know that all kinds of ownerships, big and small, must be encouraged to thrive by good regulation – because City too were once under an ownership of much more modest means. They will know that dragging the Premier League and their fellow clubs to court does immeasurable damage. Yet it would appear the edict from Abu Dhabi is irresistible.

The soft power of that Middle East fossil fuel wealth stretches to other owners of other clubs too, and it will be intriguing to see how they respond. Some have chosen to mollify CFG, the great mothership at which the Manchester entity sits at the centre. The Premier League is well past that point now. Clubs such as Liverpool, Arsenal and Tottenham Hotspur, who spend what they earn, can see a future in which they simply cannot compete.

City meanwhile, have a squad to renew over the coming years with Kevin De Bruyne hinting this week at a potential summer departure. Other greats such as Kyle Walker, John Stones and Bernardo Silva are nearer to the end and soon perhaps Pep Guardiola and his sporting director Txiki Begiristain will decide they have done their time. Replacing them will not come cheap, and the commercial deals and renewals that are agreed in the next few years will be critical.

The Premier League’s pre-eminence has always been complex. An awkward, shifting coalition of 20 different partners. It has had its rebellions and its divides, but this is new. An attack from one of its members that suits only themselves and perhaps one other – at the expense of the success of all the rest.
