The Difference Between Hypothesis and Theory

A hypothesis is an assumption, an idea that is proposed for the sake of argument so that it can be tested to see if it might be true.

In the scientific method, the hypothesis is constructed before any applicable research has been done, apart from a basic background review. You ask a question, read up on what has been studied before, and then form a hypothesis.

A hypothesis is usually tentative; it's an assumption or suggestion made strictly for the objective of being tested.

A theory , in contrast, is a principle that has been formed as an attempt to explain things that have already been substantiated by data. It is used in the names of a number of principles accepted in the scientific community, such as the Big Bang Theory . Because of the rigors of experimentation and control, it is understood to be more likely to be true than a hypothesis is.

In non-scientific use, however, hypothesis and theory are often used interchangeably to mean simply an idea, speculation, or hunch, with theory being the more common choice.

Since this casual use does away with the distinctions upheld by the scientific community, hypothesis and theory are prone to being wrongly interpreted even when they are encountered in scientific contexts—or at least, contexts that allude to scientific study without making the critical distinction that scientists employ when weighing hypotheses and theories.

The most common occurrence is when theory is interpreted—and sometimes even gleefully seized upon—to mean something having less truth value than other scientific principles. (The word law applies to principles so firmly established that they are almost never questioned, such as the law of gravity.)

This mistake is one of projection: since we use theory in general to mean something lightly speculated, then it's implied that scientists must be talking about the same level of uncertainty when they use theory to refer to their well-tested and reasoned principles.

The distinction has come to the forefront particularly on occasions when the content of science curricula in schools has been challenged—notably, when a school board in Georgia put stickers on textbooks stating that evolution was "a theory, not a fact, regarding the origin of living things." As Kenneth R. Miller, a cell biologist at Brown University, has said , a theory "doesn’t mean a hunch or a guess. A theory is a system of explanations that ties together a whole bunch of facts. It not only explains those facts, but predicts what you ought to find from other observations and experiments.”

While theories are never completely infallible, they form the basis of scientific reasoning because, as Miller said "to the best of our ability, we’ve tested them, and they’ve held up."

  • proposition
  • supposition

hypothesis , theory , law mean a formula derived by inference from scientific data that explains a principle operating in nature.

hypothesis implies insufficient evidence to provide more than a tentative explanation.

theory implies a greater range of evidence and greater likelihood of truth.

law implies a statement of order and relation in nature that has been found to be invariable under the same conditions.

  • 2005 , Ronald H. Pine, http://www.csicop.org/specialarticles/show/intelligent_design_or_no_model_creationism , 15 October 2005: Far too many of us have been taught in school that a scientist, in the course of trying to figure something out, will first come up with a " hypothesis " (a guess or surmise—not necessarily even an "educated" guess). ... [But t]he word " hypothesis " should be used, in science, exclusively for a reasoned, sensible, knowledge-informed explanation for why some phenomenon exists or occurs. An hypothesis can be as yet untested; can have already been tested; may have been falsified; may have not yet been falsified, although tested; or may have been tested in a myriad of ways countless times without being falsified; and it may come to be universally accepted by the scientific community. An understanding of the word " hypothesis ," as used in science, requires a grasp of the principles underlying Occam's Razor and Karl Popper's thought in regard to " falsifiability "—including the notion that any respectable scientific hypothesis must, in principle, be "capable of" being proven wrong (if it should, in fact, just happen to be wrong), but none can ever be proved to be true. One aspect of a proper understanding of the word " hypothesis ," as used in science, is that only a vanishingly small percentage of hypotheses could ever potentially become a theory.

Dictionary definition of hypothesis

An educated guess or a proposed explanation for a phenomenon or a pattern of observations. "The experiment yielded results that supported the initial hypothesis ."

Detailed meaning of hypothesis

It is a statement that can be tested through scientific experimentation or further observation. In scientific research, a hypothesis is used as a starting point for an investigation, and it serves as a basis for designing experiments and collecting data to either support or disprove it. A hypothesis typically consists of two parts: the independent variable, which is the factor being tested, and the dependent variable, which is the effect that is being observed. The hypothesis states the expected relationship between the two variables. For example, if a scientist wants to test the effect of a new drug on blood pressure, the independent variable would be the drug and the dependent variable would be the blood pressure. The hypothesis in this case would be "The new drug will lower blood pressure" A hypothesis is a crucial step in the scientific method as it guides the research and helps to focus on a specific question or problem. The results of the research and experimentation can support or disprove the hypothesis , and it can lead to new discoveries and knowledge. In summary, a hypothesis is an educated guess or proposed explanation for a phenomenon or a pattern of observations, it's a statement that can be tested through scientific experimentation or further observation, it's a crucial step in the scientific method that guides the research and helps to focus on a specific question or problem.

Example sentences containing hypothesis

1. The scientist formulated a hypothesis to explain the observed phenomenon. 2. The hypothesis proposed by the researcher challenged the existing theories in the field. 3. The students conducted experiments to test their hypothesis about plant growth. 4. The hypothesis stated that increased exposure to sunlight would improve mood. 5. The team developed a hypothesis to investigate the effects of a new drug on cancer cells. 6. The hypothesis suggested that regular exercise would lead to improved cognitive function.

History and etymology of hypothesis

The noun ' hypothesis ' draws its linguistic lineage from the combination of two ancient Greek elements. The first part, 'hypo,' originates from the Greek word 'hupo,' meaning 'under' or 'beneath.' The second component, 'thesis,' derives from 'tithēmi,' meaning 'to place' or 'to put forth.' In the context of scientific inquiry and philosophical discourse, the term ' hypothesis ' embodies the notion of putting forth an educated guess or proposition that lies beneath the surface of empirical observation. It signifies a preliminary and testable explanation for a phenomenon or a pattern of observations. Thus, the etymology of ' hypothesis ' underscores its foundational role in the systematic process of scientific inquiry, where ideas are posited as a starting point for further investigation and analysis.

flow chart of scientific method

hypothesis , something supposed or taken for granted, with the object of following out its consequences (Greek hypothesis , “a putting under,” the Latin equivalent being suppositio ).

Discussion with Kara Rogers of how the scientific model is used to test a hypothesis or represent a theory

In planning a course of action, one may consider various alternatives , working out each in detail. Although the word hypothesis is not typically used in this case, the procedure is virtually the same as that of an investigator of crime considering various suspects. Different methods may be used for deciding what the various alternatives may be, but what is fundamental is the consideration of a supposal as if it were true, without actually accepting it as true. One of the earliest uses of the word in this sense was in geometry . It is described by Plato in the Meno .

The most important modern use of a hypothesis is in relation to scientific investigation . A scientist is not merely concerned to accumulate such facts as can be discovered by observation: linkages must be discovered to connect those facts. An initial puzzle or problem provides the impetus , but clues must be used to ascertain which facts will help yield a solution. The best guide is a tentative hypothesis, which fits within the existing body of doctrine. It is so framed that, with its help, deductions can be made that under certain factual conditions (“initial conditions”) certain other facts would be found if the hypothesis were correct.

The concepts involved in the hypothesis need not themselves refer to observable objects. However, the initial conditions should be able to be observed or to be produced experimentally, and the deduced facts should be able to be observed. William Harvey ’s research on circulation in animals demonstrates how greatly experimental observation can be helped by a fruitful hypothesis. While a hypothesis can be partially confirmed by showing that what is deduced from it with certain initial conditions is actually found under those conditions, it cannot be completely proved in this way. What would have to be shown is that no other hypothesis would serve. Hence, in assessing the soundness of a hypothesis, stress is laid on the range and variety of facts that can be brought under its scope. Again, it is important that it should be capable of being linked systematically with hypotheses which have been found fertile in other fields.

If the predictions derived from the hypothesis are not found to be true, the hypothesis may have to be given up or modified. The fault may lie, however, in some other principle forming part of the body of accepted doctrine which has been utilized in deducing consequences from the hypothesis. It may also lie in the fact that other conditions, hitherto unobserved, are present beside the initial conditions, affecting the result. Thus the hypothesis may be kept, pending further examination of facts or some remodeling of principles. A good illustration of this is to be found in the history of the corpuscular and the undulatory hypotheses about light .

168 Accesses

The word “hypothesis” is of ancient Greek origin and composed of two parts: “hypo” for “under,” and “thesis” for “to put there”; in Latin, this translated “to suppose” or “supposition”; made up of “sub” [under] and “positum” [put there]. It refers to something that we put there, maybe to start with, maybe to stay with us as an installation. Hence in modern English we say “ let us hypothesize, suppose,” or “let us put it that … .,” and then we start the argument by developing implications and reaching conclusions. The term “hypothesis” marks a space of possibilities in several ways. Firstly, it is the uncertain starting point from which firmer conclusions might be drawn. Public reasoning examines how, from uncertain hypotheses, neither true nor false, we can nevertheless reach useful conclusions. Secondly, the hypothesis is the end point of a logical process of firming up on reality through scientific enquiry. Scientific methodology makes hypothesis testing the gold standard...

Other forms: hypotheses

In science, a hypothesis is an idea or explanation that you then test through study and experimentation. Outside science, a theory or guess can also be called a hypothesis .

A hypothesis is something more than a wild guess but less than a well-established theory. In science, a hypothesis needs to go through a lot of testing before it gets labeled a theory. In the non-scientific world, the word is used a lot more loosely. A detective might have a hypothesis about a crime, and a mother might have a hypothesis about who spilled juice on the rug. Anyone who uses the word hypothesis is making a guess.
