13.1 Formatting a Research Paper

Learning objectives.

• Identify the major components of a research paper written using American Psychological Association (APA) style.
• Apply general APA style and formatting conventions in a research paper.

In this chapter, you will learn how to use APA style , the documentation and formatting style followed by the American Psychological Association, as well as MLA style , from the Modern Language Association. There are a few major formatting styles used in academic texts, including AMA, Chicago, and Turabian:

• AMA (American Medical Association) for medicine, health, and biological sciences
• APA (American Psychological Association) for education, psychology, and the social sciences
• Chicago—a common style used in everyday publications like magazines, newspapers, and books
• MLA (Modern Language Association) for English, literature, arts, and humanities
• Turabian—another common style designed for its universal application across all subjects and disciplines

While all the formatting and citation styles have their own use and applications, in this chapter we focus our attention on the two styles you are most likely to use in your academic studies: APA and MLA.

If you find that the rules of proper source documentation are difficult to keep straight, you are not alone. Writing a good research paper is, in and of itself, a major intellectual challenge. Having to follow detailed citation and formatting guidelines as well may seem like just one more task to add to an already-too-long list of requirements.

Following these guidelines, however, serves several important purposes. First, it signals to your readers that your paper should be taken seriously as a student’s contribution to a given academic or professional field; it is the literary equivalent of wearing a tailored suit to a job interview. Second, it shows that you respect other people’s work enough to give them proper credit for it. Finally, it helps your reader find additional materials if he or she wishes to learn more about your topic.

Furthermore, producing a letter-perfect APA-style paper need not be burdensome. Yes, it requires careful attention to detail. However, you can simplify the process if you keep these broad guidelines in mind:

• Work ahead whenever you can. Chapter 11 “Writing from Research: What Will I Learn?” includes tips for keeping track of your sources early in the research process, which will save time later on.
• Get it right the first time. Apply APA guidelines as you write, so you will not have much to correct during the editing stage. Again, putting in a little extra time early on can save time later.
• Use the resources available to you. In addition to the guidelines provided in this chapter, you may wish to consult the APA website at http://www.apa.org or the Purdue University Online Writing lab at http://owl.english.purdue.edu , which regularly updates its online style guidelines.

General Formatting Guidelines

This chapter provides detailed guidelines for using the citation and formatting conventions developed by the American Psychological Association, or APA. Writers in disciplines as diverse as astrophysics, biology, psychology, and education follow APA style. The major components of a paper written in APA style are listed in the following box.

These are the major components of an APA-style paper:

Body, which includes the following:

• Headings and, if necessary, subheadings to organize the content
• In-text citations of research sources
• References page

All these components must be saved in one document, not as separate documents.

The title page of your paper includes the following information:

• Title of the paper
• Author’s name
• Name of the institution with which the author is affiliated
• Header at the top of the page with the paper title (in capital letters) and the page number (If the title is lengthy, you may use a shortened form of it in the header.)

List the first three elements in the order given in the previous list, centered about one third of the way down from the top of the page. Use the headers and footers tool of your word-processing program to add the header, with the title text at the left and the page number in the upper-right corner. Your title page should look like the following example.

The next page of your paper provides an abstract , or brief summary of your findings. An abstract does not need to be provided in every paper, but an abstract should be used in papers that include a hypothesis. A good abstract is concise—about one hundred fifty to two hundred fifty words—and is written in an objective, impersonal style. Your writing voice will not be as apparent here as in the body of your paper. When writing the abstract, take a just-the-facts approach, and summarize your research question and your findings in a few sentences.

In Chapter 12 “Writing a Research Paper” , you read a paper written by a student named Jorge, who researched the effectiveness of low-carbohydrate diets. Read Jorge’s abstract. Note how it sums up the major ideas in his paper without going into excessive detail.

Write an abstract summarizing your paper. Briefly introduce the topic, state your findings, and sum up what conclusions you can draw from your research. Use the word count feature of your word-processing program to make sure your abstract does not exceed one hundred fifty words.

Depending on your field of study, you may sometimes write research papers that present extensive primary research, such as your own experiment or survey. In your abstract, summarize your research question and your findings, and briefly indicate how your study relates to prior research in the field.

Margins, Pagination, and Headings

APA style requirements also address specific formatting concerns, such as margins, pagination, and heading styles, within the body of the paper. Review the following APA guidelines.

Use these general guidelines to format the paper:

• Set the top, bottom, and side margins of your paper at 1 inch.
• Use double-spaced text throughout your paper.
• Use a standard font, such as Times New Roman or Arial, in a legible size (10- to 12-point).
• Use continuous pagination throughout the paper, including the title page and the references section. Page numbers appear flush right within your header.
• Section headings and subsection headings within the body of your paper use different types of formatting depending on the level of information you are presenting. Additional details from Jorge’s paper are provided.

Begin formatting the final draft of your paper according to APA guidelines. You may work with an existing document or set up a new document if you choose. Include the following:

• Your title page
• The abstract you created in Note 13.8 “Exercise 1”
• Correct headers and page numbers for your title page and abstract

APA style uses section headings to organize information, making it easy for the reader to follow the writer’s train of thought and to know immediately what major topics are covered. Depending on the length and complexity of the paper, its major sections may also be divided into subsections, sub-subsections, and so on. These smaller sections, in turn, use different heading styles to indicate different levels of information. In essence, you are using headings to create a hierarchy of information.

The following heading styles used in APA formatting are listed in order of greatest to least importance:

• Section headings use centered, boldface type. Headings use title case, with important words in the heading capitalized.
• Subsection headings use left-aligned, boldface type. Headings use title case.
• The third level uses left-aligned, indented, boldface type. Headings use a capital letter only for the first word, and they end in a period.
• The fourth level follows the same style used for the previous level, but the headings are boldfaced and italicized.
• The fifth level follows the same style used for the previous level, but the headings are italicized and not boldfaced.

Visually, the hierarchy of information is organized as indicated in Table 13.1 “Section Headings” .

Table 13.1 Section Headings

A college research paper may not use all the heading levels shown in Table 13.1 “Section Headings” , but you are likely to encounter them in academic journal articles that use APA style. For a brief paper, you may find that level 1 headings suffice. Longer or more complex papers may need level 2 headings or other lower-level headings to organize information clearly. Use your outline to craft your major section headings and determine whether any subtopics are substantial enough to require additional levels of headings.

Working with the document you developed in Note 13.11 “Exercise 2” , begin setting up the heading structure of the final draft of your research paper according to APA guidelines. Include your title and at least two to three major section headings, and follow the formatting guidelines provided above. If your major sections should be broken into subsections, add those headings as well. Use your outline to help you.

Because Jorge used only level 1 headings, his Exercise 3 would look like the following:

Citation Guidelines

In-text citations.

Throughout the body of your paper, include a citation whenever you quote or paraphrase material from your research sources. As you learned in Chapter 11 “Writing from Research: What Will I Learn?” , the purpose of citations is twofold: to give credit to others for their ideas and to allow your reader to follow up and learn more about the topic if desired. Your in-text citations provide basic information about your source; each source you cite will have a longer entry in the references section that provides more detailed information.

In-text citations must provide the name of the author or authors and the year the source was published. (When a given source does not list an individual author, you may provide the source title or the name of the organization that published the material instead.) When directly quoting a source, it is also required that you include the page number where the quote appears in your citation.

This information may be included within the sentence or in a parenthetical reference at the end of the sentence, as in these examples.

Epstein (2010) points out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Here, the writer names the source author when introducing the quote and provides the publication date in parentheses after the author’s name. The page number appears in parentheses after the closing quotation marks and before the period that ends the sentence.

Addiction researchers caution that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (Epstein, 2010, p. 137).

Here, the writer provides a parenthetical citation at the end of the sentence that includes the author’s name, the year of publication, and the page number separated by commas. Again, the parenthetical citation is placed after the closing quotation marks and before the period at the end of the sentence.

As noted in the book Junk Food, Junk Science (Epstein, 2010, p. 137), “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive.”

Here, the writer chose to mention the source title in the sentence (an optional piece of information to include) and followed the title with a parenthetical citation. Note that the parenthetical citation is placed before the comma that signals the end of the introductory phrase.

David Epstein’s book Junk Food, Junk Science (2010) pointed out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Another variation is to introduce the author and the source title in your sentence and include the publication date and page number in parentheses within the sentence or at the end of the sentence. As long as you have included the essential information, you can choose the option that works best for that particular sentence and source.

Citing a book with a single author is usually a straightforward task. Of course, your research may require that you cite many other types of sources, such as books or articles with more than one author or sources with no individual author listed. You may also need to cite sources available in both print and online and nonprint sources, such as websites and personal interviews. Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.2 “Citing and Referencing Techniques” and Section 13.3 “Creating a References Section” provide extensive guidelines for citing a variety of source types.

Writing at Work

APA is just one of several different styles with its own guidelines for documentation, formatting, and language usage. Depending on your field of interest, you may be exposed to additional styles, such as the following:

• MLA style. Determined by the Modern Languages Association and used for papers in literature, languages, and other disciplines in the humanities.
• Chicago style. Outlined in the Chicago Manual of Style and sometimes used for papers in the humanities and the sciences; many professional organizations use this style for publications as well.
• Associated Press (AP) style. Used by professional journalists.

References List

The brief citations included in the body of your paper correspond to the more detailed citations provided at the end of the paper in the references section. In-text citations provide basic information—the author’s name, the publication date, and the page number if necessary—while the references section provides more extensive bibliographical information. Again, this information allows your reader to follow up on the sources you cited and do additional reading about the topic if desired.

The specific format of entries in the list of references varies slightly for different source types, but the entries generally include the following information:

• The name(s) of the author(s) or institution that wrote the source
• The year of publication and, where applicable, the exact date of publication
• The full title of the source
• For books, the city of publication
• For articles or essays, the name of the periodical or book in which the article or essay appears
• For magazine and journal articles, the volume number, issue number, and pages where the article appears
• For sources on the web, the URL where the source is located

The references page is double spaced and lists entries in alphabetical order by the author’s last name. If an entry continues for more than one line, the second line and each subsequent line are indented five spaces. Review the following example. ( Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.3 “Creating a References Section” provides extensive guidelines for formatting reference entries for different types of sources.)

In APA style, book and article titles are formatted in sentence case, not title case. Sentence case means that only the first word is capitalized, along with any proper nouns.

Key Takeaways

• Following proper citation and formatting guidelines helps writers ensure that their work will be taken seriously, give proper credit to other authors for their work, and provide valuable information to readers.
• Working ahead and taking care to cite sources correctly the first time are ways writers can save time during the editing stage of writing a research paper.
• APA papers usually include an abstract that concisely summarizes the paper.
• APA papers use a specific headings structure to provide a clear hierarchy of information.
• In APA papers, in-text citations usually include the name(s) of the author(s) and the year of publication.
• In-text citations correspond to entries in the references section, which provide detailed bibliographical information about a source.

Formatting Requirements

Page layout, margins and numbering, workday student support.

Graduate students can find "how to" guides and support information on our Workday support page .

Your scholarly approach may call for a different presentational method. These are the requirements and recommendations for text-based theses.

For a text-based thesis, or the text portions of a thesis, the page size must be 8.5" x 11", and the text must be in a single, page-wide column. Do not use two or more columns in your thesis.

The text of the thesis is written in paragraph form.

• the first line of each paragraph should be indented, OR
• there should be a larger space between paragraphs than there is between lines.

Each chapter should generally start at the top of a new page.

Left: 1.25 inches (32 mm) is recommended if you intend to bind copies of your thesis; 1 inch minimum.

Right, top, and bottom: 1 inch recommended; 0.75 inches (19 mm) minimum

Page Numbering

Preliminary pages:.

• must be numbered in lower case Roman numerals (ii, iii, iv, etc.)
• the title page is "i" but this number must not appear on the page
• numbering begins at "ii" on the committee page
• the first page of the abstract is page iii

Body of thesis:

• must be numbered in Arabic numerals (1, 2, 3, etc.)
• the first page of the text is "1"
• subsequent pages are numbered continuously throughout, including pages with tables and figures, bibliographies, appendices, and index

Whole thesis:

• every page except the title page must have a number on it
• there must be no blank pages in the thesis.

Page numberS:

• must be placed at least .5 inches (12 mm) from the edge of the page
• may be either in the lower centre or on the top or lower right of the page, when the page is viewed in portrait view. Lower right is preferred.

Landscape Pages

Landscape pages must be orientated in your PDF so that they are readable without rotation. You do not need to change the location or orientation of the page number, but may if you wish.

Facing Pages

Facing pages are not acceptable; you must use one-sided layout and pagination. If the caption for a figure, table, etc., cannot appear on the same page as its accompanying illustration, place the illustration on a separate page after the caption.

General Formatting Guidelines

Follow these guidelines throughout your paper:

• Double space text
• Header for student and professional papers includes the page number in the upper right hand corner
• Single space after ending punctuation
• Font size and style: Times New Roman 12 pt, Arial 11 pt, Calibri 11 pt, or Georgia 11 pt
• Use the same font type and size throughout the paper (exceptions for figure images, computer code, and footnotes - see 2.19 in APA Manual)
• Margins: 1 inch on all sides
• Left align paragraphs and leave ragged (uneven) margins on the right
• Indention: use 0.5 inch indention for the first line of every paragraph (use tab key for consistency)

Formatting Title Page

The 7th edition Publication Manual for APA introduced the student and professional papers. The major difference between these two types of papers is found on the title page. Please, see the guidelines below for formatting the title page of your document. Also note, follow your professors' guidelines for formatting the title page.

General Title Page Guidelines:

• Double space
• The title should summarize the main idea and be focused/succinct (avoid unnecessary words)
• Title written in title case (the first letter of each word is capitalized), bold, centered, and positioned in the upper half of the title page
• Use the author(s) first name, middle initial, and last name as the author's byline

Student Papers:

• title of the paper
• name of the author(s)
• author affiliation (department and institution name)
• course number and name 
• instructor name
• assignment due date (i.e. November 4, 2020)
• page number (in the header)

Professional Papers:

• author affiliation
• author note
• running head (abbreviated title) - Flush with left margin and written in all capital letters

Formatting Headings

Follow this format for headings (see 2.27 of the Publication Manual for additional details):

Level 1 headings are written in bold title case and aligned to the center. The text begins as a new paragraph.

Level 2 headings are written in bold title case and aligned flush to the left. The text begins as a new paragraph.

Level 3 headings are written in bold, italicized title case, and aligned flush to the left. The text begins as a new paragraph.

Level 4 headings are written in bold title case, indented from the left, and end with a period. The text begins after the period and continues like a regular paragraph.

Level 5 headings are written in bold, italicized title case, indented from the left, and end with a period. The text begins after the period and continues like a regular paragraph.

Formatting Reference List

The following are guidelines for formatting your reference list:

• Start on a new page after the last page of text
• Label the page Reference(s) with a capitalized R, written in bold and centered
• Double space all entries
• Use hanging indent for reference entries (first line of the reference is flush with left margin, subsequent lines are indented 0.5 inches)
• Order alphabetically (see chapter 9 section 44-49 for additional instructions on entry order)

• Synthesizing Information from Sources
• MLA Documentation
• APA In-Text Citations
• Writing a Research Paper
• APA Handout
• Acceptable fonts and sizes: Size 12-point Times New Roman;11-point Arial, Calibri, and Georgia; or 10-point Lucida.
• Body of paper is aligned left
• Running head (by instructor preference) in header, left aligned
• Page number in header right aligned
• Line Spacing – double throughout
• Tab in the first line of a paragraph ½” or .5
• Title is bolded, centered with proper capitalization
• Level 1 heading on 2nd page of paper, centered and bolded and is usually the title of the paper, never the word Introduction.
• References is the last page of the paper
• 1” margins – top, bottom, left, right.
• Word margins are set in Layout or in File/Page Setup/Margins.
• Acceptable fonts and sizes: Size 12-point Times New Roman; 11-point Arial, Calibri, and Georgia;10-point Lucida; or other legible font as approved by instructor.
• Font and font size are important for readability.
• Do not use bold except for section headings if section headings are used.
• Do not use all caps except for the title of the paper in the Header or an acronym (NATO, AIDS).
• Do not use italics or underlining unless there is a rule that says to use them.
• Left align – this is the usual default setting.
• Do not block or justify where the right margin is uneven.
• Alignment can be set in the Paragraph box if the icon is not visible.

Line Spacing

• Double space –throughout the entire document.
• Check default settings in the Paragraph box and reset per instructions under Paragraph setting (see below).

Paragraph Settings

Some programs such as Word 2007 and later have defaults in the Paragraph box which interferes with proper double spacing. The settings in the Paragraph dialogue box should be as follows to have proper double spacing.

• Indentation (on top) should be set at 0 left and 0 right.
• Spacing (on the lower left) should be set to 0 Before and 0 After.
• Line Spacing (on the lower right) should be set to double.
• Check the box that says “Don’t add space between paragraphs of the same style.”
• Click Default (at the bottom) and select Yes to change defaults.

In Google docs , you can change Paragraph settings under Spacing to 0 next to Before and 0 next to After by going into the double spacing tool and clicking Custom Settings.  You will have to select (highlight) the entire paper including the heading in the upper left before making the change once the paper is typed.

In Pages , you can change the Paragraph settings by clicking on Format on the top navigation bar and then Paragraph. Remember that you have to highlight (select) the entire paper including the heading in the upper left before making change in Paragraph once the paper is typed.

First Line of a Paragraph

• Indent the first word of a paragraph 1/2” or .5 from the left margin.
• The Tab default is usually at this setting.  If not, reset defaults.

Spacing after a Period or Other End Punctuation

In the 7th edition of APA, only one space is used after the end of a sentence.

Page Number and Running Head

• In Word, click on the Insert tab and then click on Page Number in the menu bar. It will give you the option of where to insert the page number.
• Choose to insert the page number at the top of the page, right aligned.
• The page number appears on every page of the document, including the title page.
• Place the cursor left of the number and type in the running head.
• Total length of the running head is 50 characters and spaces.
• The running head is in all caps.
• After you typed click tab until the running head is left aligned in the header.
• Use a plain header format.
• Do not use bold, underlining, quotation marks, or a different font or color for the title.
• Do not use the word page or any abbreviation of the word page such as pg. or p. between the running head and the actual page number.

Heading Levels

There are five possible heading levels in APA style.

• Level 1 headings are used for top-level or main sections – they are bolded and in the center of the page.
• Level 2 and Level 3 headings are subsections of Level 1 – they are also bolded, but they are left aligned.
• Levels 4 and 5 headings are bolded, italicized, indented, and followed by a period.

APA does not use the word Introduction. The Level 1 heading at the beginning of an APA paper is the bolded and centered title of the paper, typed on the first page of the paper after the title page.

See pages 47 - 49 in the APA Publication Manual for more detailed information.

The student paper must include a title page. The following items are included on the student title page unless otherwise indicated by the instructor:

• The running head is an abbreviation of the title, written in all-caps, left aligned in the header up to 50 character and spaces long (if less than 50 character and spaces long then the entire title can be in the header)
• Page number is right aligned in the header
• The running head and page numbers appear on every page of the paper.
• All the text on the title page is centered and double spaced with proper capitalization (except for the header)
• Title is a maximum of three to four spaces below the header
• Directly below the title is the student author’s first and last name
• On the next line is the college/institution’s name, fully spelled out with proper capitalization
• Below the institution name is the course number and course name, ex:  COU 1234: Introduction to APA Usage
• On the next line is the instructor name, ex: Prof. I. Knowalot
• On the last line is the assignment due date, ex: February 29, 2028

If you are asked to prepare an abstract for your research paper, click Insert/Page Break to get to the top of a new page, and center the word Abstract in bold on the first line. Abstracts are typically no more than 250 words. They are usually a single paragraph with no indentation at the start of the paragraph. Otherwise, they follow the same formatting rules including double spacing.

Reference Page

• After the last section of your paper insert a page break.
• Type the word References, bolded, centered with proper capitalization
• The References page is double spaced.
• Each reference entry is left-aligned and formatted with a hanging indent.
• To create the hanging indent, highlight the reference entries and go into the Paragraph box.
• Under Special, select Hanging from the drop down menu. Once selected, the default under By should be .5’.
• Remember that your list has to be alphabetized by author. If there is no author or group author, use the title.
• There are no extra spaces in between entries.

117 Formatting a Research Paper

Learning objectives.

• Identify the major components of a research paper written using American Psychological Association (APA) style.
• Apply general APA style and formatting conventions in a research paper.

In this chapter, you will learn how to use APA style , the documentation and formatting style followed by the American Psychological Association, as well as MLA style , from the Modern Language Association. There are a few major formatting styles used in academic texts, including AMA, Chicago, and Turabian:

• AMA (American Medical Association) for medicine, health, and biological sciences
• APA (American Psychological Association) for education, psychology, and the social sciences
• Chicago—a common style used in everyday publications like magazines, newspapers, and books
• MLA (Modern Language Association) for English, literature, arts, and humanities
• Turabian—another common style designed for its universal application across all subjects and disciplines

While all the formatting and citation styles have their own use and applications, in this chapter we focus our attention on the two styles you are most likely to use in your academic studies: APA and MLA.

If you find that the rules of proper source documentation are difficult to keep straight, you are not alone. Writing a good research paper is, in and of itself, a major intellectual challenge. Having to follow detailed citation and formatting guidelines as well may seem like just one more task to add to an already-too-long list of requirements.

Following these guidelines, however, serves several important purposes. First, it signals to your readers that your paper should be taken seriously as a student’s contribution to a given academic or professional field; it is the literary equivalent of wearing a tailored suit to a job interview. Second, it shows that you respect other people’s work enough to give them proper credit for it. Finally, it helps your reader find additional materials if he or she wishes to learn more about your topic.

Furthermore, producing a letter-perfect APA-style paper need not be burdensome. Yes, it requires careful attention to detail. However, you can simplify the process if you keep these broad guidelines in mind:

• Work ahead whenever you can. Chapter 11 “Writing from Research: What Will I Learn?” includes tips for keeping track of your sources early in the research process, which will save time later on.
• Get it right the first time. Apply APA guidelines as you write, so you will not have much to correct during the editing stage. Again, putting in a little extra time early on can save time later.
• Use the resources available to you. In addition to the guidelines provided in this chapter, you may wish to consult the APA website at http://www.apa.org or the Purdue University Online Writing lab at http://owl.english.purdue.edu , which regularly updates its online style guidelines.

General Formatting Guidelines

This chapter provides detailed guidelines for using the citation and formatting conventions developed by the American Psychological Association, or APA. Writers in disciplines as diverse as astrophysics, biology, psychology, and education follow APA style. The major components of a paper written in APA style are listed in the following box.

These are the major components of an APA-style paper:

Body, which includes the following:

• Headings and, if necessary, subheadings to organize the content
• In-text citations of research sources
• References page

All these components must be saved in one document, not as separate documents.

The title page of your paper includes the following information:

• Title of the paper
• Author’s name
• Name of the institution with which the author is affiliated
• Header at the top of the page with the paper title (in capital letters) and the page number (If the title is lengthy, you may use a shortened form of it in the header.)

List the first three elements in the order given in the previous list, centered about one third of the way down from the top of the page. Use the headers and footers tool of your word-processing program to add the header, with the title text at the left and the page number in the upper-right corner. Your title page should look like the following example.

The next page of your paper provides an abstract , or brief summary of your findings. An abstract does not need to be provided in every paper, but an abstract should be used in papers that include a hypothesis. A good abstract is concise—about one hundred fifty to two hundred fifty words—and is written in an objective, impersonal style. Your writing voice will not be as apparent here as in the body of your paper. When writing the abstract, take a just-the-facts approach, and summarize your research question and your findings in a few sentences.

In Chapter 12 “Writing a Research Paper” , you read a paper written by a student named Jorge, who researched the effectiveness of low-carbohydrate diets. Read Jorge’s abstract. Note how it sums up the major ideas in his paper without going into excessive detail.

Write an abstract summarizing your paper. Briefly introduce the topic, state your findings, and sum up what conclusions you can draw from your research. Use the word count feature of your word-processing program to make sure your abstract does not exceed one hundred fifty words.

Depending on your field of study, you may sometimes write research papers that present extensive primary research, such as your own experiment or survey. In your abstract, summarize your research question and your findings, and briefly indicate how your study relates to prior research in the field.

Margins, Pagination, and Headings

APA style requirements also address specific formatting concerns, such as margins, pagination, and heading styles, within the body of the paper. Review the following APA guidelines.

Use these general guidelines to format the paper:

• Set the top, bottom, and side margins of your paper at 1 inch.
• Use double-spaced text throughout your paper.
• Use a standard font, such as Times New Roman or Arial, in a legible size (10- to 12-point).
• Use continuous pagination throughout the paper, including the title page and the references section. Page numbers appear flush right within your header.
• Section headings and subsection headings within the body of your paper use different types of formatting depending on the level of information you are presenting. Additional details from Jorge’s paper are provided.

Begin formatting the final draft of your paper according to APA guidelines. You may work with an existing document or set up a new document if you choose. Include the following:

• Your title page
• The abstract you created in Note 13.8 “Exercise 1”
• Correct headers and page numbers for your title page and abstract

APA style uses section headings to organize information, making it easy for the reader to follow the writer’s train of thought and to know immediately what major topics are covered. Depending on the length and complexity of the paper, its major sections may also be divided into subsections, sub-subsections, and so on. These smaller sections, in turn, use different heading styles to indicate different levels of information. In essence, you are using headings to create a hierarchy of information.

The following heading styles used in APA formatting are listed in order of greatest to least importance:

• Section headings use centered, boldface type. Headings use title case, with important words in the heading capitalized.
• Subsection headings use left-aligned, boldface type. Headings use title case.
• The third level uses left-aligned, indented, boldface type. Headings use a capital letter only for the first word, and they end in a period.
• The fourth level follows the same style used for the previous level, but the headings are boldfaced and italicized.
• The fifth level follows the same style used for the previous level, but the headings are italicized and not boldfaced.

Visually, the hierarchy of information is organized as indicated in Table 13.1 “Section Headings” .

Table 13.1 Section Headings

A college research paper may not use all the heading levels shown in Table 13.1 “Section Headings” , but you are likely to encounter them in academic journal articles that use APA style. For a brief paper, you may find that level 1 headings suffice. Longer or more complex papers may need level 2 headings or other lower-level headings to organize information clearly. Use your outline to craft your major section headings and determine whether any subtopics are substantial enough to require additional levels of headings.

Working with the document you developed in Note 13.11 “Exercise 2” , begin setting up the heading structure of the final draft of your research paper according to APA guidelines. Include your title and at least two to three major section headings, and follow the formatting guidelines provided above. If your major sections should be broken into subsections, add those headings as well. Use your outline to help you.

Because Jorge used only level 1 headings, his Exercise 3 would look like the following:

Citation Guidelines

In-text citations.

Throughout the body of your paper, include a citation whenever you quote or paraphrase material from your research sources. As you learned in Chapter 11 “Writing from Research: What Will I Learn?” , the purpose of citations is twofold: to give credit to others for their ideas and to allow your reader to follow up and learn more about the topic if desired. Your in-text citations provide basic information about your source; each source you cite will have a longer entry in the references section that provides more detailed information.

In-text citations must provide the name of the author or authors and the year the source was published. (When a given source does not list an individual author, you may provide the source title or the name of the organization that published the material instead.) When directly quoting a source, it is also required that you include the page number where the quote appears in your citation.

This information may be included within the sentence or in a parenthetical reference at the end of the sentence, as in these examples.

Epstein (2010) points out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Here, the writer names the source author when introducing the quote and provides the publication date in parentheses after the author’s name. The page number appears in parentheses after the closing quotation marks and before the period that ends the sentence.

Addiction researchers caution that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (Epstein, 2010, p. 137).

Here, the writer provides a parenthetical citation at the end of the sentence that includes the author’s name, the year of publication, and the page number separated by commas. Again, the parenthetical citation is placed after the closing quotation marks and before the period at the end of the sentence.

As noted in the book Junk Food, Junk Science (Epstein, 2010, p. 137), “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive.”

Here, the writer chose to mention the source title in the sentence (an optional piece of information to include) and followed the title with a parenthetical citation. Note that the parenthetical citation is placed before the comma that signals the end of the introductory phrase.

David Epstein’s book Junk Food, Junk Science (2010) pointed out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Another variation is to introduce the author and the source title in your sentence and include the publication date and page number in parentheses within the sentence or at the end of the sentence. As long as you have included the essential information, you can choose the option that works best for that particular sentence and source.

Citing a book with a single author is usually a straightforward task. Of course, your research may require that you cite many other types of sources, such as books or articles with more than one author or sources with no individual author listed. You may also need to cite sources available in both print and online and nonprint sources, such as websites and personal interviews. Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.2 “Citing and Referencing Techniques” and Section 13.3 “Creating a References Section” provide extensive guidelines for citing a variety of source types.

Writing at Work

APA is just one of several different styles with its own guidelines for documentation, formatting, and language usage. Depending on your field of interest, you may be exposed to additional styles, such as the following:

• MLA style. Determined by the Modern Languages Association and used for papers in literature, languages, and other disciplines in the humanities.
• Chicago style. Outlined in the Chicago Manual of Style and sometimes used for papers in the humanities and the sciences; many professional organizations use this style for publications as well.
• Associated Press (AP) style. Used by professional journalists.

References List

The brief citations included in the body of your paper correspond to the more detailed citations provided at the end of the paper in the references section. In-text citations provide basic information—the author’s name, the publication date, and the page number if necessary—while the references section provides more extensive bibliographical information. Again, this information allows your reader to follow up on the sources you cited and do additional reading about the topic if desired.

The specific format of entries in the list of references varies slightly for different source types, but the entries generally include the following information:

• The name(s) of the author(s) or institution that wrote the source
• The year of publication and, where applicable, the exact date of publication
• The full title of the source
• For books, the city of publication
• For articles or essays, the name of the periodical or book in which the article or essay appears
• For magazine and journal articles, the volume number, issue number, and pages where the article appears
• For sources on the web, the URL where the source is located

The references page is double spaced and lists entries in alphabetical order by the author’s last name. If an entry continues for more than one line, the second line and each subsequent line are indented five spaces. Review the following example. ( Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.3 “Creating a References Section” provides extensive guidelines for formatting reference entries for different types of sources.)

In APA style, book and article titles are formatted in sentence case, not title case. Sentence case means that only the first word is capitalized, along with any proper nouns.

Key Takeaways

• Following proper citation and formatting guidelines helps writers ensure that their work will be taken seriously, give proper credit to other authors for their work, and provide valuable information to readers.
• Working ahead and taking care to cite sources correctly the first time are ways writers can save time during the editing stage of writing a research paper.
• APA papers usually include an abstract that concisely summarizes the paper.
• APA papers use a specific headings structure to provide a clear hierarchy of information.
• In APA papers, in-text citations usually include the name(s) of the author(s) and the year of publication.
• In-text citations correspond to entries in the references section, which provide detailed bibliographical information about a source.

MLA recommends using 12-point Times New Roman font or another readable typeface (e.g. serif ).

Line Spacing & Margins

Use double-spacing throughout the entire paper.

Leave 1 inch margins on the top, bottom, and each side.

Indent the first line of each paragraph half an inch from the left margin.

Quotes longer than 4 lines should be written as a block of text a half an inch from the left margin.

Heading and Title

An MLA research paper does not need a title page, but your instructor may require one. If no instructions are given, follow the MLA guidelines below:

Type the following one inch from the top of the first page, flush with the left margin (double spacing throughout).

Your Instructor's Name

Course Number or Name

Center the title on the next line. Follow the rules for capitalization. Do not italicize, underline, or bold the title. An exception is when your title includes a title.  Example:  The Attitude toward Violence in A Clockwork Orange

Indent the next line and begin typing your text.

Include your last name and page numbers in the upper right-hand corner of every page. The page numbers will be one-half inch from the top and flush with the right margin. If your instructor prefers no page number on the first page, begin numbering from 2 on the second page.

Styling Headings and Subheadings

According to the MLA Style Center website, writers should avoid using headings in shorter papers. If you are writing a longer research paper, you may want to include headings and subheadings to help organize the sections of your paper. Advice from the MLA Style Center :

"Levels

The paper or chapter title is the first level of heading, and it must be the most prominent.

Headings should be styled in descending order of prominence. After the first level, the other headings are subheadings—that is, they are subordinate. Font styling and size are used to signal prominence. In general, a boldface, larger font indicates prominence; a smaller font, italics, and lack of bold can be used to signal subordination. For readability, don’t go overboard: avoid using all capital letters for headings (in some cases, small capitals may be acceptable):

Heading Level 1

Heading Level 2

Heading Level 3

Note that word-processing software often has built-in heading styles.

Consistency

Consistency in the styling of headings and subheadings is key to signaling to readers the structure of a research project. That is, each level 1 heading should appear in the same style and size, as should each level 2 heading, and so on. Generally, avoid numbers and letters to designate heads unless you are working in a discipline where doing so is conventional. Note that a heading labeled “1” requires a subsequent heading labeled “2,” and a heading labeled “a” requires a subsequent heading labeled “b.” 

In a project that is not professionally designed and published, headings should be flush with the left margin, to avoid confusion with block quotations. (The exception is the paper or chapter title, which is centered in MLA style.)

For readability, it is helpful to include a line space above and below a heading, as shown in this post.

No internal heading level should have only one instance. For example, if you have one level 1 heading, you need to have a second level 1 heading. (The exceptions are the paper or chapter title and the headings for notes and the list of works cited.) You should also generally have text under each heading.

Capitalization

Capitalize headings like the titles of works, as explained in section 1.2 of the MLA Handbook.

The shorter, the better."

II. Formatting Guidelines

All copies of a thesis or dissertation must have the following uniform margins throughout the entire document:

• Left: 1″ (or 1 1/4" to ensure sufficient room for binding the work if desired)
• Right: 1″
• Bottom: 1″ (with allowances for page numbers; see section on Pagination )
• Top: 1″

Exceptions : The first page of each chapter (including the introduction, if any) begins 2″ from the top of the page. Also, the headings on the title page, abstract, first page of the dedication/ acknowledgements/preface (if any), and first page of the table of contents begin 2″ from the top of the page.

Non-traditional theses or dissertations such as whole works comprised of digital, artistic, video, or performance materials (i.e., no written text, chapters, or articles) are acceptable if approved by your committee and graduate program. A PDF document with a title page, copyright page, and abstract at minimum are required to be submitted along with any relevant supplemental files.

Fonts must be 10, 11, or 12 points in size. Superscripts and subscripts (e.g., formulas, or footnote or endnote numbers) should be no more than 2 points smaller than the font size used for the body of the text.

Space and indent your thesis or dissertation following these guidelines:

• The text must appear in a single column on each page and be double-spaced throughout the document. Do not arrange chapter text in multiple columns.
• New paragraphs must be indicated by a consistent tab indentation throughout the entire document.
• The document text must be left-justified, not centered or right-justified.
• For blocked quotations, indent the entire text of the quotation consistently from the left margin.
• Ensure headings are not left hanging alone on the bottom of a prior page. The text following should be moved up or the heading should be moved down. This is something to check near the end of formatting, as other adjustments to text and spacing may change where headings appear on the page.

Exceptions : Blocked quotations, notes, captions, legends, and long headings must be single-spaced throughout the document and double-spaced between items.

Paginate your thesis or dissertation following these guidelines:

• Use lower case Roman numerals (ii, iii, iv, etc.) on all pages preceding the first page of chapter one. The title page counts as page i, but the number does not appear. Therefore, the first page showing a number will be the copyright page with ii at the bottom.
• Arabic numerals (beginning with 1, 2, 3, 4, etc.) start at chapter one or the introduction, if applicable. Arabic numbers must be included on all pages of the text, illustrations, notes, and any other materials that follow. Thus, the first page of chapter one will show an Arabic numeral 1, and numbering of all subsequent pages will follow in order.
• Do not use page numbers accompanied by letters, hyphens, periods, or parentheses (e.g., 1., 1-2, -1-, (1), or 1a).
• Center all page numbers at the bottom of the page, 1/2″ from the bottom edge.
• Pages must not contain running headers or footers, aside from page numbers.
• If your document contains landscape pages (pages in which the top of the page is the long side of a sheet of paper), make sure that your page numbers still appear in the same position and direction as they do on pages with standard portrait orientation for consistency. This likely means the page number will be centered on the short side of the paper and the number will be sideways relative to the landscape page text. See these additional instructions for assistance with pagination on landscape pages in Microsoft Word .

Format footnotes for your thesis or dissertation following these guidelines:

• Footnotes must be placed at the bottom of the page separated from the text by a solid line one to two inches long.
• Begin at the left page margin, directly below the solid line.
• Single-space footnotes that are more than one line long.
• Include one double-spaced line between each note.
• Most software packages automatically space footnotes at the bottom of the page depending on their length. It is acceptable if the note breaks within a sentence and carries the remainder into the footnote area of the next page. Do not indicate the continuation of a footnote.
• Number all footnotes with Arabic numerals. You may number notes consecutively within each chapter starting over with number 1 for the first note in each chapter, or you may number notes consecutively throughout the entire document.
• Footnote numbers must precede the note and be placed slightly above the line (superscripted). Leave no space between the number and the note.
• While footnotes should be located at the bottom of the page, do not place footnotes in a running page footer, as they must remain within the page margins.

Endnotes are an acceptable alternative to footnotes. Format endnotes for your thesis or dissertation following these guidelines:

• Always begin endnotes on a separate page either immediately following the end of each chapter, or at the end of your entire document. If you place all endnotes at the end of the entire document, they must appear after the appendices and before the references.
• Include the heading “ENDNOTES” in all capital letters, and center it 1″ below the top of the first page of your endnotes section(s).
• Single-space endnotes that are more than one line long.
• Number all endnotes with Arabic numerals. You may number notes consecutively within each chapter starting over with number 1 for the first note in each chapter, or you may number notes consecutively throughout the entire document.
• Endnote numbers must precede the note and be placed slightly above the line (superscripted). Leave no space between the number and the note.

Tables, figures, and illustrations vary widely by discipline. Therefore, formatting of these components is largely at the discretion of the author.

For example, headings and captions may appear above or below each of these components.

These components may each be placed within the main text of the document or grouped together in a separate section.

Space permitting, headings and captions for the associated table, figure, or illustration must be on the same page.

The use of color is permitted as long as it is consistently applied as part of the finished component (e.g., a color-coded pie chart) and not extraneous or unprofessional (e.g., highlighting intended solely to draw a reader's attention to a key phrase). The use of color should be reserved primarily for tables, figures, illustrations, and active website or document links throughout your thesis or dissertation.

The format you choose for these components must be consistent throughout the thesis or dissertation.

Ensure each component complies with margin and pagination requirements.

Refer to the List of Tables, Figures, and Illustrations section for additional information.

If your thesis or dissertation has appendices, they must be prepared following these guidelines:

• Appendices must appear at the end of the document (before references) and not the chapter to which they pertain.
• When there is more than one appendix, assign each appendix a number or a letter heading (e.g., “APPENDIX 1” or “APPENDIX A”) and a descriptive title. You may number consecutively throughout the entire work (e.g., 1, 2 or A, B), or you may assign a two-part Arabic numeral with the first number designating the chapter in which it appears, separated by a period, followed by a second number or letter to indicate its consecutive placement (e.g., “APPENDIX 3.2” is the second appendix referred to in Chapter Three).
• Include the chosen headings in all capital letters, and center them 1″ below the top of the page.
• All appendix headings and titles must be included in the table of contents.
• Page numbering must continue throughout your appendix or appendices. Ensure each appendix complies with margin and pagination requirements.

You are required to list all the references you consulted. For specific details on formatting your references, consult and follow a style manual or professional journal that is used for formatting publications and citations in your discipline.

Your reference pages must be prepared following these guidelines:

• If you place references after each chapter, the references for the last chapter must be placed immediately following the chapter and before the appendices.
• If you place all references at the end of the thesis or dissertation, they must appear after the appendices as the final component in the document.
• Select an appropriate heading for this section based on the style manual you are using (e.g., “REFERENCES”, “BIBLIOGRAPHY”, or “WORKS CITED”).
• Include the chosen heading in all capital letters, and center it 1″ below the top of the page.
• References must be single-spaced within each entry.
• Include one double-spaced line between each reference.
• Page numbering must continue throughout your references section. Ensure references comply with margin and pagination requirements.

In some cases, students gain approval from their academic program to include in their thesis or dissertation previously published (or submitted, in press, or under review) journal articles or similar materials that they have authored. For more information about including previously published works in your thesis or dissertation, see the section on Use of Your Own Previously Published Materials and the section on Copyrighting.

If your academic program has approved inclusion of such materials, please note that these materials must match the formatting guidelines set forth in this Guide regardless of how the material was formatted for publication.

Some specific formatting guidelines to consider include:

• Fonts, margins, chapter headings, citations, and references must all match the formatting and placement used within the rest of the thesis or dissertation.
• If appropriate, published articles can be included as separate individual chapters within the thesis or dissertation.
• A separate abstract to each chapter should not be included.
• The citation for previously published work must be included as the first footnote (or endnote) on the first page of the chapter.
• Do not include typesetting notations often used when submitting manuscripts to a publisher (i.e., insert table x here).
• The date on the title page should be the year in which your committee approves the thesis or dissertation, regardless of the date of completion or publication of individual chapters.
• If you would like to include additional details about the previously published work, this information can be included in the preface for the thesis or dissertation.

Writing Research Papers

• Formatting Research Papers

Research papers written in APA style should follow the formatting rules specified in the Publication Manual of the American Psychological Association .  Most research papers that are written for psychology courses at UCSD, including the B.S. Degree Research Paper and the Honors Thesis, have to follow APA format.  Here we discuss the formatting of research papers according to APA style.

How to Format a Research Paper in APA Style

For the most accurate and comprehensive information on formatting papers in APA style, we recommend referring directly to the Publication Manual of the American Psychological Association. Reputable online sources (e.g., the official APA Style website and the Purdue University Online Writing Lab’s guide to APA style) are also recommended. 

According to the Publication Manual, the major sections and components of APA style research papers should adhere to the following guidelines.  Note that how closely these guidelines are followed may vary depending on the course and instructor.  

General Formatting Rules

• Papers should have at least 1-in. margins on all sides. 1
• All text should be double spaced . 1
• Times New Roman, 12 point font is preferred. 1
• All lines of text should be flush-left and should not be justified, except where noted in the Manual. 1
• The first line of every paragraph should be indented. Exceptions to the indenting rule are the Abstract, quotations, titles and headings, as well as Tables and Figures. 1
• Pages should be numbered at the top right, with the title page numbered page 1, the Abstract numbered page 2, and the text starting on page 3. 1
• An abbreviated title called the Running Head should be placed at the top of each page, flush-left in uppercase letters. 1
• Two spaces should be used after punctuation marks at the end of each sentence (in other words, there should be two spaces after the period that ends each sentence). 2

Formatting the Title Page

• The title should be typed in the upper half of the title page, centered, and with the first letters of all but minor words capitalized. 3
• The name(s) of the author(s) should be typed below the title and followed with the institutional affiliation(s) of the author(s). 3
• An Author Note should appear below the aforementioned items. The Author Note can have up to four paragraphs.  These respectively describe the author(s)’ departmental and institutional affiliation, any changes in affiliation, acknowledgments, and contact information. 3

Formatting the Abstract

• The Abstract typically should not exceed 250 words. 4
• The Abstract should be placed on a separate page, with the label Abstract appearing at the top center of that page and followed by the text of the Abstract. 4
• The Abstract should not be indented. 4

Formatting the Main Body of Text

• The main body of text should begin on a separate page after the Abstract. 5
• It should begin with the Introduction section. 5
• The Introduction section should be titled with the title of the research paper and not the word “Introduction.” The title should appear at the top of the page, centered, and should not be bolded. 5
• The remainder of the text should be flush-left, with each new paragraph indented except where noted above (see General Formatting Rules ). 5
• Each of the subsequent sections of the paper should be prefaced with a heading. APA guidelines specify different heading formats (for more information on Levels of Headings , see below). 5

Formatting References

• The references section should begin on a separate page after the main body of text. 6
• It should begin with the word “References” placed at the top of the page and centered. 6
• All references should be listed in alphabetical order by the last name of the first author of each reference. 6
• All references should be double-spaced and should use a hanging indent format wherein the first line of each reference is flush-left and all subsequent lines of that reference are indented (with that pattern repeating for each reference). 6

As of the sixth edition of the Publication Manual of the American Psychological Association (released in 2010), the five possible levels of heading in APA-formatted manuscripts are: 7

• Level 1: centered, bold, on a separate line, and the first letters of all but minor words capitalized.
• Level 2: flush-left, bold, on a separate line, and the first letters of all but minor words capitalized.
• Level 3: indented, bold, as a paragraph heading (the first part of a paragraph; regular text follows on the same line), and in lowercase letters ending with a period.
• Level 4: indented, bold, italicized, as a paragraph heading (the first part of a paragraph; regular text follows on the same line), and in lowercase letters ending with a period.
• Level 5: indented, not bold, italicized, as a paragraph heading (the first part of a paragraph; regular text follows on the same line), and in lowercase letters ending with a period.

Depending on the structure of your research paper, some or all of the five levels of headings may be used.  The headings have a “hierarchical nested structure” where Level 1 is the highest and Level 5 is the lowest.  For example, you may have a research paper which uses all five levels of heading as follows:

You are here

On this site, you will find general information about MLA and APA format styles with specific requirements regarding title pages, headings, margins, and pagination. Regardless of the style manual you follow, use only standard fonts for your paper. Do not enlarge the font to make your paper appear longer; do not make the font smaller so you can fit your paper into the prescribed number of pages. Do not use a cursive or decorative font.

This site offers only examples of the more common citations students use. For a wider range of topics, you need to consult the MLA Handbook for Writers of Research Papers or the Publication Manual of the American Psychological Association. Both style books are available in the bookstore and at the library.

MLA Formats:

General format and title page: Your research paper needs to be typed and double-spaced on standard-sized paper (8.5 X 11 inches). Use one-inch margins on all four sides of each page. Unless your professor specifically calls for one, a title page is unnecessary. In place of a title page, MLA style requires a heading on the first page of your paper. The heading appears in the top, left corner of the first page, double-spaced. The heading includes your name, your professor's name, the course you are taking, and the date. Center your title one line below the heading. Double-space the title if it extends past the first line. Write your title in capital and lower-case letters. Do not underline your title or put it in quotation marks. The page number preceded by your last name should appear in the upper right corner one-half inch from the top. Do not use a hyphen, period, or any other punctuation with the page number. Use this example as a guide:

Headings: If your paper is long you may divide it into sections (for example, "Literature Review," "Research Method and Results," and "Discussion"). In some cases, you may divide one or more of those sections into other sections (for example, you might divide the second section listed above into "Participants," "Interview Protocol," and "Caveats"). Your purpose would be to improve clarity. Divisions might help a reader better follow a discussion that extends for twenty-five written pages. Consistently using the same style of heading for each level informs the reader whether the upcoming topic is a subtopic of the previous discussion or another central issue. Select a form for each level of division (for example, you might write Level 1 centered, caps and lower case; Level 2 flush left, lower case only, etc.); use the same form for the same level your paper. Regardless of the system you choose, the title on the title page should conform to MLA standards.

Margins and spacing: All margins should measure one inch. Page numbers will appear within the top margin, but no other text should extend past the one-inch margins. Indent five spaces to begin paragraphs. Double-space the text of your paper.

Pagination: Number all pages of your paper in the upper right corner, one-half inch from the top. Do not write -2- or p. 2. The number should appear by itself with no punctuation.

APA Formats

General format and title page: Your research paper needs to be typed, double-spaced on standard-sized paper (8.5 X 11 inches). Use one to one-and-a-half inch margins on all four sides of each page. APA (American Psychological Association) calls for a title page. A running head on this page is not necessary unless you are submitting your paper for publication. At the top of your title page, flush right and one-half inch from the top edge of the paper (inside your top margin), you will write what is called a "manuscript header." A manuscript header consists of one or two key words from you title followed by the page number (see example). Your title will appear centered on this page, written in capital and lower-case letters. If your title extends past one line, double-space between lines. Your name will appear centered and in capital and lower-case letters one double-spaced line below your title. Your university name (Oregon State University) will be placed one double-spaced line below your name. If you are a communication major, you also will include below the institution's name the title of your department. For example:

The pages of your manuscript should be numbered consecutively, beginning with the title page, as part of the manuscript header in the upper right corner of each page. Your references should begin on a separate page from the text of the paper under the label "References" (with no quotation marks, underlining, etc.), centered at the top of the page. Appendices and notes should be formatted similarly.

Headings: APA style prescribes five heading levels, but they vary according to the length of your paper. If you are writing a formal piece to be submitted to an undergraduate conference, closely consult the APA style book. For class papers, ask for your professor's preference. If no preference is given, follow the suggestions written in this section under MLA.

Margins and spacing: Leave margins of at least one inch on all sides of your paper. Page numbers will appear within the top margin, but no other text should extend into the margins. Indent five to seven spaces to begin paragraphs. Double-space the text of your paper.

Pagination: Page numbers should be placed in the top margin one inch from the right side of the paper. The number should appear by itself with no punctuation.

Margin (Composition Format) Definition

• Ph.D., Rhetoric and English, University of Georgia
• M.A., Modern English and American Literature, University of Leicester
• B.A., English, State University of New York

The part of a page that's outside the main body of text  is a margin .  Word processors let us set margins so that they're either aligned ( justified ) or ragged ( unjustified ). For most school or college writing assignments (including articles , essays , and reports ), only the left-hand margin should be justified. (This glossary entry, for instance, is left justified only.)

As a general rule, margins of at least one inch should appear on all four sides of a hard copy. The specific guidelines below have been drawn from the most commonly used style guides . Also, see:

• Block Quotation
• Indentation
• Justification

From the Latin, "border"

• APA Guidelines on Margins "Leave uniform margins of at least 1 in. (2.54 cm) at the top, bottom, left, and right of every page. Combined with a uniform typeface and font size, uniform margins enhance readability and provide a consistent gauge for estimating article length." ( Publication Manual of the American Psychological Association , 6th ed. APA. 2010)
• MLA Guidelines on Margins "Except for page numbers, leave margins  of one inch at the top and bottom and on both sides of the text. . . . If you lack 8½-by-11-inch paper and use a larger size, do not print the text in an area greater than 6½ by 9 inches. Indent the first word of a paragraph one-half inch from the left margin. Indent set-off quotations one inch from the left margin." ( MLA Handbook for Writers of Research Papers , 7th ed. The Modern Language Association of America, 2009)
• Turabian's Chicago-Style Guidelines on Margins "Nearly all papers in the United States are produced on standard pages of 8½ x 11 inches. Leave a margin of at least one inch on all four edges of the page. For a thesis or dissertation intended to be bound, you may need to leave a bigger margin on the left side--usually 1½ inches. "Be sure that any material placed in headers or footers, including page numbers and other identifiers . . ., falls within the margins specified in your local guidelines." (Kate L. Turabian et al., A Manual for Writers of Research Papers, Theses, and Dissertations: Chicago Style for Students and Researchers , 8th ed. University of Chicago Press, 2013)
• Guidelines on Margins in Business Letters and Reports "Use a 2-inch top margin for the first page of a business letter printed on letterhead stationery. Any second and succeeding pages of a business letter have 1-inch top margins. Use left justification. "Select the side margins according to the number of words in the letter and the size of the font used to prepare the letter. Set the margins after keying the letter and using the word count feature of your word processing program. . . . " Reports and manuscripts may be prepared with either 1.25-inch left and right margins or 1-inch left and right margins, depending upon the preference of the originator. If the report or manuscript is to be bound on the left, allow an additional 0.25 inch for the left margin. "The first page of major parts (title page, table of contents, bibliography, etc.) and the opening page of sections or chapters require a 2-inch top margin, 2.25 inches for top-bound documents." (James L. Clark and Lyn R. Clark, How 10: A Handbook for Office Workers , 10th ed. Thomson/South-Western, 2003)
• The New Typography "In the New Typography margins often almost entirely disappear. Of course, type cannot in most cases be set right up to the edge of the paper, which would hinder legibility. In small items of printed matter, 12 to 24 points are the minimum margin required; in posters 48 points. On the other hand, borders of solid red or black can be taken right up to the edge, since unlike type they do not require a white margin to achieve their best effect." (Jan Tschichold, "The Principles of the New Typography," in Texts on Type: Critical Writings on Typography , ed. by Steven Heller and Philip B. Meggs. Allworth Communications, 2001)

The Effects of Social Media on Mental Health

University of XYZ

This study examines the relationship between social media use and mental health among college students. Data was collected through a survey of 500 students at the University of XYZ. Results suggest that social media use is significantly related to symptoms of depression and anxiety, and that the negative effects of social media are greater among frequent users.

Social media has become an increasingly important aspect of modern life, especially among young adults. While social media can have many positive effects, such as connecting people across distances and sharing information, there is growing concern about its impact on mental health. This study aims to examine the relationship between social media use and mental health among college students.

Participants: Participants were 500 college students at the University of XYZ, recruited through online advertisements and flyers posted on campus. Participants ranged in age from 18 to 25, with a mean age of 20.5 years. The sample was 60% female, 40% male, and 5% identified as non-binary or gender non-conforming.

Data was collected through an online survey administered through Qualtrics. The survey consisted of several measures, including the Patient Health Questionnaire-9 (PHQ-9) for depression symptoms, the Generalized Anxiety Disorder-7 (GAD-7) for anxiety symptoms, and questions about social media use.

Procedure :

Participants were asked to complete the online survey at their convenience. The survey took approximately 20-30 minutes to complete. Data was analyzed using descriptive statistics, correlations, and multiple regression analysis.

Results indicated that social media use was significantly related to symptoms of depression (r = .32, p < .001) and anxiety (r = .29, p < .001). Regression analysis indicated that frequency of social media use was a significant predictor of both depression symptoms (β = .24, p < .001) and anxiety symptoms (β = .20, p < .001), even when controlling for age, gender, and other relevant factors.

The results of this study suggest that social media use is associated with symptoms of depression and anxiety among college students. The negative effects of social media are greater among frequent users. These findings have important implications for mental health professionals and educators, who should consider addressing the potential negative effects of social media use in their work with young adults.

References :

References should be listed in alphabetical order according to the author’s last name. For example:

• Chou, H. T. G., & Edge, N. (2012). “They are happier and having better lives than I am”: The impact of using Facebook on perceptions of others’ lives. Cyberpsychology, Behavior, and Social Networking, 15(2), 117-121.

Note: This is just a sample Example do not use this in your assignment.

MLA (Modern Language Association) Format

MLA (Modern Language Association) Format is as follows:

• Page Layout : Use 8.5 x 11-inch white paper, with 1-inch margins on all sides. The font should be 12-point Times New Roman or a similar serif font.
• Heading and Title : The first page of your research paper should include a heading and a title. The heading should include your name, your instructor’s name, the course title, and the date. The title should be centered and in title case (capitalizing the first letter of each important word).
• In-Text Citations : Use parenthetical citations to indicate the source of your information. The citation should include the author’s last name and the page number(s) of the source. For example: (Smith 23).
• Works Cited Page : At the end of your paper, include a Works Cited page that lists all the sources you used in your research. Each entry should include the author’s name, the title of the work, the publication information, and the medium of publication.
• Formatting Quotations : Use double quotation marks for short quotations and block quotations for longer quotations. Indent the entire quotation five spaces from the left margin.
• Formatting the Body : Use a clear and readable font and double-space your text throughout. The first line of each paragraph should be indented one-half inch from the left margin.

Title: The Impact of Video Games on Aggression Levels

Video games have become a popular form of entertainment among people of all ages. However, the impact of video games on aggression levels has been a subject of debate among scholars and researchers. While some argue that video games promote aggression and violent behavior, others argue that there is no clear link between video games and aggression levels. This research paper aims to explore the impact of video games on aggression levels among young adults.

Background:

The debate on the impact of video games on aggression levels has been ongoing for several years. According to the American Psychological Association, exposure to violent media, including video games, can increase aggression levels in children and adolescents. However, some researchers argue that there is no clear evidence to support this claim. Several studies have been conducted to examine the impact of video games on aggression levels, but the results have been mixed.

Methodology:

This research paper used a quantitative research approach to examine the impact of video games on aggression levels among young adults. A sample of 100 young adults between the ages of 18 and 25 was selected for the study. The participants were asked to complete a questionnaire that measured their aggression levels and their video game habits.

The results of the study showed that there was a significant correlation between video game habits and aggression levels among young adults. The participants who reported playing violent video games for more than 5 hours per week had higher aggression levels than those who played less than 5 hours per week. The study also found that male participants were more likely to play violent video games and had higher aggression levels than female participants.

The findings of this study support the claim that video games can increase aggression levels among young adults. However, it is important to note that the study only examined the impact of video games on aggression levels and did not take into account other factors that may contribute to aggressive behavior. It is also important to note that not all video games promote violence and aggression, and some games may have a positive impact on cognitive and social skills.

Conclusion :

In conclusion, this research paper provides evidence to support the claim that video games can increase aggression levels among young adults. However, it is important to conduct further research to examine the impact of video games on other aspects of behavior and to explore the potential benefits of video games. Parents and educators should be aware of the potential impact of video games on aggression levels and should encourage young adults to engage in a variety of activities that promote cognitive and social skills.

Title: The Impact of Social Media on Political Engagement

Name: John Smith

Class: POLS 101

Professor: Dr. Jane Doe

Date: April 8, 2023

I. Introduction:

Social media has become an integral part of our daily lives. People use social media platforms like Facebook, Twitter, and Instagram to connect with friends and family, share their opinions, and stay informed about current events. With the rise of social media, there has been a growing interest in understanding its impact on various aspects of society, including political engagement. In this paper, I will examine the relationship between social media use and political engagement, specifically focusing on how social media influences political participation and political attitudes.

II. Literature Review:

There is a growing body of literature on the impact of social media on political engagement. Some scholars argue that social media has a positive effect on political participation by providing new channels for political communication and mobilization (Delli Carpini & Keeter, 1996; Putnam, 2000). Others, however, suggest that social media can have a negative impact on political engagement by creating filter bubbles that reinforce existing beliefs and discourage political dialogue (Pariser, 2011; Sunstein, 2001).

III. Methodology:

To examine the relationship between social media use and political engagement, I conducted a survey of 500 college students. The survey included questions about social media use, political participation, and political attitudes. The data was analyzed using descriptive statistics and regression analysis.

Iv. Results:

The results of the survey indicate that social media use is positively associated with political participation. Specifically, respondents who reported using social media to discuss politics were more likely to have participated in a political campaign, attended a political rally, or contacted a political representative. Additionally, social media use was found to be associated with more positive attitudes towards political engagement, such as increased trust in government and belief in the effectiveness of political action.

V. Conclusion:

The findings of this study suggest that social media has a positive impact on political engagement, by providing new opportunities for political communication and mobilization. However, there is also a need for caution, as social media can also create filter bubbles that reinforce existing beliefs and discourage political dialogue. Future research should continue to explore the complex relationship between social media and political engagement, and develop strategies to harness the potential benefits of social media while mitigating its potential negative effects.

Title: on margin-based generalization prediction in deep neural networks.

Abstract: Understanding generalization in deep neural networks is an active area of research. A promising avenue of exploration has been that of margin measurements: the shortest distance to the decision boundary for a given sample or that sample's representation internal to the network. Margin-based complexity measures have been shown to be correlated with the generalization ability of deep neural networks in some circumstances but not others. The reasons behind the success or failure of these metrics are currently unclear. In this study, we examine margin-based generalization prediction methods in different settings. We motivate why these metrics sometimes fail to accurately predict generalization and how they can be improved. First, we analyze the relationship between margins measured in the input space and sample noise. We find that different types of sample noise can have a very different effect on the overall margin of a network that has modeled noisy data. Following this, we empirically evaluate how robust margins measured at different representational spaces are at predicting generalization. We find that these metrics have several limitations and that a large margin does not exhibit a strong correlation with empirical risk in many cases. Finally, we introduce a new margin-based measure that incorporates an approximation of the underlying data manifold. It is empirically demonstrated that this measure is generally more predictive of generalization than all other margin-based measures. Furthermore, we find that this measurement also outperforms other contemporary complexity measures on a well-known generalization prediction benchmark. In addition, we analyze the utility and limitations of this approach and find that this metric is well aligned with intuitions expressed in prior work.

Startup companies solve many of today’s most challenging problems, such as the decarbonisation of the economy or the development of novel life-saving vaccines. Startups are a vital source of innovation, yet the most innovative are also the least likely to survive. The probability of success of startups has been shown to relate to several firm-level factors such as industry, location and the economy of the day. Still, attention has increasingly considered internal factors relating to the firm’s founding team, including their previous experiences and failures, their centrality in a global network of other founders and investors, as well as the team’s size. The effects of founders’ personalities on the success of new ventures are, however, mainly unknown. Here, we show that founder personality traits are a significant feature of a firm’s ultimate success. We draw upon detailed data about the success of a large-scale global sample of startups (n = 21,187). We find that the Big Five personality traits of startup founders across 30 dimensions significantly differ from that of the population at large. Key personality facets that distinguish successful entrepreneurs include a preference for variety, novelty and starting new things (openness to adventure), like being the centre of attention (lower levels of modesty) and being exuberant (higher activity levels). We do not find one ’Founder-type’ personality; instead, six different personality types appear. Our results also demonstrate the benefits of larger, personality-diverse teams in startups, which show an increased likelihood of success. The findings emphasise the role of the diversity of personality types as a novel dimension of team diversity that influences performance and success.

Introduction.

The success of startups is vital to economic growth and renewal, with a small number of young, high-growth firms creating a disproportionately large share of all new jobs 1 , 2 . Startups create jobs and drive economic growth, and they are also an essential vehicle for solving some of society’s most pressing challenges.

As a poignant example, six centuries ago, the German city of Mainz was abuzz as the birthplace of the world’s first moveable-type press created by Johannes Gutenberg. However, in the early part of this century, it faced several economic challenges, including rising unemployment and a significant and growing municipal debt. Then in 2008, two Turkish immigrants formed the company BioNTech in Mainz with another university research colleague. Together they pioneered new mRNA-based technologies. In 2020, BioNTech partnered with US pharmaceutical giant Pfizer to create one of only a handful of vaccines worldwide for Covid-19, saving an estimated six million lives 3 . The economic benefit to Europe and, in particular, the German city where the vaccine was developed has been significant, with windfall tax receipts to the government clearing Mainz’s €1.3bn debt and enabling tax rates to be reduced, attracting other businesses to the region as well as inspiring a whole new generation of startups 4 .

While stories such as the success of BioNTech are often retold and remembered, their success is the exception rather than the rule. The overwhelming majority of startups ultimately fail. One study of 775 startups in Canada that successfully attracted external investment found only 35% were still operating seven years later 5 .

But what determines the success of these ‘lucky few’? When assessing the success factors of startups, especially in the early-stage unproven phase, venture capitalists and other investors offer valuable insights. Three different schools of thought characterise their perspectives: first, supply-side or product investors : those who prioritise investing in firms they consider to have novel and superior products and services, investing in companies with intellectual property such as patents and trademarks. Secondly, demand-side or market-based investors : those who prioritise investing in areas of highest market interest, such as in hot areas of technology like quantum computing or recurrent or emerging large-scale social and economic challenges such as the decarbonisation of the economy. Thirdly, talent investors : those who prioritise the foundation team above the startup’s initial products or what industry or problem it is looking to address.

Investors who adopt the third perspective and prioritise talent often recognise that a good team can overcome many challenges in the lead-up to product-market fit. And while the initial products of a startup may or may not work a successful and well-functioning team has the potential to pivot to new markets and new products, even if the initial ones prove untenable. Not surprisingly, an industry ‘autopsy’ into 101 tech startup failures found 23% were due to not having the right team—the number three cause of failure ahead of running out of cash or not having a product that meets the market need 6 .

Accordingly, early entrepreneurship research was focused on the personality of founders, but the focus shifted away in the mid-1980s onwards towards more environmental factors such as venture capital financing 7 , 8 , 9 , networks 10 , location 11 and due to a range of issues and challenges identified with the early entrepreneurship personality research 12 , 13 . At the turn of the 21st century, some scholars began exploring ways to combine context and personality and reconcile entrepreneurs’ individual traits with features of their environment. In her influential work ’The Sociology of Entrepreneurship’, Patricia H. Thornton 14 discusses two perspectives on entrepreneurship: the supply-side perspective (personality theory) and the demand-side perspective (environmental approach). The supply-side perspective focuses on the individual traits of entrepreneurs. In contrast, the demand-side perspective focuses on the context in which entrepreneurship occurs, with factors such as finance, industry and geography each playing their part. In the past two decades, there has been a revival of interest and research that explores how entrepreneurs’ personality relates to the success of their ventures. This new and growing body of research includes several reviews and meta-studies, which show that personality traits play an important role in both career success and entrepreneurship 15 , 16 , 17 , 18 , 19 , that there is heterogeneity in definitions and samples used in research on entrepreneurship 16 , 18 , and that founder personality plays an important role in overall startup outcomes 17 , 19 .

Motivated by the pivotal role of the personality of founders on startup success outlined in these recent contributions, we investigate two main research questions:

Which personality features characterise founders?

Do their personalities, particularly the diversity of personality types in founder teams, play a role in startup success?

We aim to understand whether certain founder personalities and their combinations relate to startup success, defined as whether their company has been acquired, acquired another company or listed on a public stock exchange. For the quantitative analysis, we draw on a previously published methodology 20 , which matches people to their ‘ideal’ jobs based on social media-inferred personality traits.

We find that personality traits matter for startup success. In addition to firm-level factors of location, industry and company age, we show that founders’ specific Big Five personality traits, such as adventurousness and openness, are significantly more widespread among successful startups. As we find that companies with multi-founder teams are more likely to succeed, we cluster founders in six different and distinct personality groups to underline the relevance of the complementarity in personality traits among founder teams. Startups with diverse and specific combinations of founder types (e. g., an adventurous ‘Leader’, a conscientious ‘Accomplisher’, and an extroverted ‘Developer’) have significantly higher odds of success.

We organise the rest of this paper as follows. In the Section " Results ", we introduce the data used and the methods applied to relate founders’ psychological traits with their startups’ success. We introduce the natural language processing method to derive individual and team personality characteristics and the clustering technique to identify personality groups. Then, we present the result for multi-variate regression analysis that allows us to relate firm success with external and personality features. Subsequently, the Section " Discussion " mentions limitations and opportunities for future research in this domain. In the Section " Methods ", we describe the data, the variables in use, and the clustering in greater detail. Robustness checks and additional analyses can be found in the Supplementary Information.

Our analysis relies on two datasets. We infer individual personality facets via a previously published methodology 20 from Twitter user profiles. Here, we restrict our analysis to founders with a Crunchbase profile. Crunchbase is the world’s largest directory on startups. It provides information about more than one million companies, primarily focused on funding and investors. A company’s public Crunchbase profile can be considered a digital business card of an early-stage venture. As such, the founding teams tend to provide information about themselves, including their educational background or a link to their Twitter account.

We infer the personality profiles of the founding teams of early-stage ventures from their publicly available Twitter profiles, using the methodology described by Kern et al. 20 . Then, we correlate this information to data from Crunchbase to determine whether particular combinations of personality traits correspond to the success of early-stage ventures. The final dataset used in the success prediction model contains n = 21,187 startup companies (for more details on the data see the Methods section and SI section  A.5 ).

Revisions of Crunchbase as a data source for investigations on a firm and industry level confirm the platform to be a useful and valuable source of data for startups research, as comparisons with other sources at micro-level, e.g., VentureXpert or PwC, also suggest that the platform’s coverage is very comprehensive, especially for start-ups located in the United States 21 . Moreover, aggregate statistics on funding rounds by country and year are quite similar to those produced with other established sources, going to validate the use of Crunchbase as a reliable source in terms of coverage of funded ventures. For instance, Crunchbase covers about the same number of investment rounds in the analogous sectors as collected by the National Venture Capital Association 22 . However, we acknowledge that the data source might suffer from registration latency (a certain delay between the foundation of the company and its actual registration on Crunchbase) and success bias in company status (the likeliness that failed companies decide to delete their profile from the database).

The definition of startup success

The success of startups is uncertain, dependent on many factors and can be measured in various ways. Due to the likelihood of failure in startups, some large-scale studies have looked at which features predict startup survival rates 23 , and others focus on fundraising from external investors at various stages 24 . Success for startups can be measured in multiple ways, such as the amount of external investment attracted, the number of new products shipped or the annual growth in revenue. But sometimes external investments are misguided, revenue growth can be short-lived, and new products may fail to find traction.

Success in a startup is typically staged and can appear in different forms and times. For example, a startup may be seen to be successful when it finds a clear solution to a widely recognised problem, such as developing a successful vaccine. On the other hand, it could be achieving some measure of commercial success, such as rapidly accelerating sales or becoming profitable or at least cash positive. Or it could be reaching an exit for foundation investors via a trade sale, acquisition or listing of its shares for sale on a public stock exchange via an Initial Public Offering (IPO).

For our study, we focused on the startup’s extrinsic success rather than the founders’ intrinsic success per se, as its more visible, objective and measurable. A frequently considered measure of success is the attraction of external investment by venture capitalists 25 . However, this is not in and of itself a good measure of clear, incontrovertible success, particularly for early-stage ventures. This is because it reflects investors’ expectations of a startup’s success potential rather than actual business success. Similarly, we considered other measures like revenue growth 26 , liquidity events 27 , 28 , 29 , profitability 30 and social impact 31 , all of which have benefits as they capture incremental success, but each also comes with operational measurement challenges.

Therefore, we apply the success definition initially introduced by Bonaventura et al. 32 , namely that a startup is acquired, acquires another company or has an initial public offering (IPO). We consider any of these major capital liquidation events as a clear threshold signal that the company has matured from an early-stage venture to becoming or is on its way to becoming a mature company with clear and often significant business growth prospects. Together these three major liquidity events capture the primary forms of exit for external investors (an acquisition or trade sale and an IPO). For companies with a longer autonomous growth runway, acquiring another company marks a similar milestone of scale, maturity and capability.

Using multifactor analysis and a binary classification prediction model of startup success, we looked at many variables together and their relative influence on the probability of the success of startups. We looked at seven categories of factors through three lenses of firm-level factors: (1) location, (2) industry, (3) age of the startup; founder-level factors: (4) number of founders, (5) gender of founders, (6) personality characteristics of founders and; lastly team-level factors: (7) founder-team personality combinations. The model performance and relative impacts on the probability of startup success of each of these categories of founders are illustrated in more detail in section  A.6 of the Supplementary Information (in particular Extended Data Fig.  19 and Extended Data Fig.  20 ). In total, we considered over three hundred variables (n = 323) and their relative significant associations with success.

The personality of founders

Besides product-market, industry, and firm-level factors (see SI section  A.1 ), research suggests that the personalities of founders play a crucial role in startup success 19 . Therefore, we examine the personality characteristics of individual startup founders and teams of founders in relationship to their firm’s success by applying the success definition used by Bonaventura et al. 32 .

Employing established methods 33 , 34 , 35 , we inferred the personality traits across 30 dimensions (Big Five facets) of a large global sample of startup founders. The startup founders cohort was created from a subset of founders from the global startup industry directory Crunchbase, who are also active on the social media platform Twitter.

To measure the personality of the founders, we used the Big Five, a popular model of personality which includes five core traits: Openness to Experience, Conscientiousness, Extraversion, Agreeableness, and Emotional stability. Each of these traits can be further broken down into thirty distinct facets. Studies have found that the Big Five predict meaningful life outcomes, such as physical and mental health, longevity, social relationships, health-related behaviours, antisocial behaviour, and social contribution, at levels on par with intelligence and socioeconomic status 36 Using machine learning to infer personality traits by analysing the use of language and activity on social media has been shown to be more accurate than predictions of coworkers, friends and family and similar in accuracy to the judgement of spouses 37 . Further, as other research has shown, we assume that personality traits remain stable in adulthood even through significant life events 38 , 39 , 40 . Personality traits have been shown to emerge continuously from those already evident in adolescence 41 and are not significantly influenced by external life events such as becoming divorced or unemployed 42 . This suggests that the direction of any measurable effect goes from founder personalities to startup success and not vice versa.

As a first investigation to what extent personality traits might relate to entrepreneurship, we use the personality characteristics of individuals to predict whether they were an entrepreneur or an employee. We trained and tested a machine-learning random forest classifier to distinguish and classify entrepreneurs from employees and vice-versa using inferred personality vectors alone. As a result, we found we could correctly predict entrepreneurs with 77% accuracy and employees with 88% accuracy (Fig.  1 A). Thus, based on personality information alone, we correctly predict all unseen new samples with 82.5% accuracy (See SI section  A.2 for more details on this analysis, the classification modelling and prediction accuracy).

We explored in greater detail which personality features are most prominent among entrepreneurs. We found that the subdomain or facet of Adventurousness within the Big Five Domain of Openness was significant and had the largest effect size. The facet of Modesty within the Big Five Domain of Agreeableness and Activity Level within the Big Five Domain of Extraversion was the subsequent most considerable effect (Fig.  1 B). Adventurousness in the Big Five framework is defined as the preference for variety, novelty and starting new things—which are consistent with the role of a startup founder whose role, especially in the early life of the company, is to explore things that do not scale easily 43 and is about developing and testing new products, services and business models with the market.

Once we derived and tested the Big Five personality features for each entrepreneur in our data set, we examined whether there is evidence indicating that startup founders naturally cluster according to their personality features using a Hopkins test (see Extended Data Figure  6 ). We discovered clear clustering tendencies in the data compared with other renowned reference data sets known to have clusters. Then, once we established the founder data clusters, we used agglomerative hierarchical clustering. This ‘bottom-up’ clustering technique initially treats each observation as an individual cluster. Then it merges them to create a hierarchy of possible cluster schemes with differing numbers of groups (See Extended Data Fig.  7 ). And lastly, we identified the optimum number of clusters based on the outcome of four different clustering performance measurements: Davies-Bouldin Index, Silhouette coefficients, Calinski-Harabas Index and Dunn Index (see Extended Data Figure  8 ). We find that the optimum number of clusters of startup founders based on their personality features is six (labelled #0 through to #5), as shown in Fig.  1 C.

To better understand the context of different founder types, we positioned each of the six types of founders within an occupation-personality matrix established from previous research 44 . This research showed that ‘each job has its own personality’ using a substantial sample of employees across various jobs. Utilising the methodology employed in this study, we assigned labels to the cluster names #0 to #5, which correspond to the identified occupation tribes that best describe the personality facets represented by the clusters (see Extended Data Fig.  9 for an overview of these tribes, as identified by McCarthy et al. 44 ).

Utilising this approach, we identify three ’purebred’ clusters: #0, #2 and #5, whose members are dominated by a single tribe (larger than 60% of all individuals in each cluster are characterised by one tribe). Thus, these clusters represent and share personality attributes of these previously identified occupation-personality tribes 44 , which have the following known distinctive personality attributes (see also Table  1 ):

Accomplishers (#0) —Organised & outgoing. confident, down-to-earth, content, accommodating, mild-tempered & self-assured.

Leaders (#2) —Adventurous, persistent, dispassionate, assertive, self-controlled, calm under pressure, philosophical, excitement-seeking & confident.

Fighters (#5) —Spontaneous and impulsive, tough, sceptical, and uncompromising.

We labelled these clusters with the tribe names, acknowledging that labels are somewhat arbitrary, based on our best interpretation of the data (See SI section  A.3 for more details).

For the remaining three clusters #1, #3 and #4, we can see they are ‘hybrids’, meaning that the founders within them come from a mix of different tribes, with no one tribe representing more than 50% of the members of that cluster. However, the tribes with the largest share were noted as #1 Experts/Engineers, #3 Fighters, and #4 Operators.

To label these three hybrid clusters, we examined the closest occupations to the median personality features of each cluster. We selected a name that reflected the common themes of these occupations, namely:

Experts/Engineers (#1) as the closest roles included Materials Engineers and Chemical Engineers. This is consistent with this cluster’s personality footprint, which is highest in openness in the facets of imagination and intellect.

Developers (#3) as the closest roles include Application Developers and related technology roles such as Business Systems Analysts and Product Managers.

Operators (#4) as the closest roles include service, maintenance and operations functions, including Bicycle Mechanic, Mechanic and Service Manager. This is also consistent with one of the key personality traits of high conscientiousness in the facet of orderliness and high agreeableness in the facet of humility for founders in this cluster.

Founder-Level Factors of Startup Success. ( A ), Successful entrepreneurs differ from successful employees. They can be accurately distinguished using a classifier with personality information alone. ( B ), Successful entrepreneurs have different Big Five facet distributions, especially on adventurousness, modesty and activity level. ( C ), Founders come in six different types: Fighters, Operators, Accomplishers, Leaders, Engineers and Developers (FOALED) ( D ), Each founder Personality-Type has its distinct facet.

Together, these six different types of startup founders (Fig.  1 C) represent a framework we call the FOALED model of founder types—an acronym of Fighters, Operators, Accomplishers, Leaders, Engineers and D evelopers.

Each founder’s personality type has its distinct facet footprint (for more details, see Extended Data Figure  10 in SI section  A.3 ). Also, we observe a central core of correlated features that are high for all types of entrepreneurs, including intellect, adventurousness and activity level (Fig.  1 D).To test the robustness of the clustering of the personality facets, we compare the mean scores of the individual facets per cluster with a 20-fold resampling of the data and find that the clusters are, overall, largely robust against resampling (see Extended Data Figure  11 in SI section  A.3 for more details).

We also find that the clusters accord with the distribution of founders’ roles in their startups. For example, Accomplishers are often Chief Executive Officers, Chief Financial Officers, or Chief Operating Officers, while Fighters tend to be Chief Technical Officers, Chief Product Officers, or Chief Commercial Officers (see Extended Data Fig.  12 in SI section  A.4 for more details).

The ensemble theory of success

While founders’ individual personality traits, such as Adventurousness or Openness, show to be related to their firms’ success, we also hypothesise that the combination, or ensemble, of personality characteristics of a founding team impacts the chances of success. The logic behind this reasoning is complementarity, which is proposed by contemporary research on the functional roles of founder teams. Examples of these clear functional roles have evolved in established industries such as film and television, construction, and advertising 45 . When we subsequently explored the combinations of personality types among founders and their relationship to the probability of startup success, adjusted for a range of other factors in a multi-factorial analysis, we found significantly increased chances of success for mixed foundation teams:

Initially, we find that firms with multiple founders are more likely to succeed, as illustrated in Fig.  2 A, which shows firms with three or more founders are more than twice as likely to succeed than solo-founded startups. This finding is consistent with investors’ advice to founders and previous studies 46 . We also noted that some personality types of founders increase the probability of success more than others, as shown in SI section  A.6 (Extended Data Figures  16 and 17 ). Also, we note that gender differences play out in the distribution of personality facets: successful female founders and successful male founders show facet scores that are more similar to each other than are non-successful female founders to non-successful male founders (see Extended Data Figure  18 ).

The Ensemble Theory of Team-Level Factors of Startup Success. ( A ) Having a larger founder team elevates the chances of success. This can be due to multiple reasons, e.g., a more extensive network or knowledge base but also personality diversity. ( B ) We show that joint personality combinations of founders are significantly related to higher chances of success. This is because it takes more than one founder to cover all beneficial personality traits that ‘breed’ success. ( C ) In our multifactor model, we show that firms with diverse and specific combinations of types of founders have significantly higher odds of success.

Access to more extensive networks and capital could explain the benefits of having more founders. Still, as we find here, it also offers a greater diversity of combined personalities, naturally providing a broader range of maximum traits. So, for example, one founder may be more open and adventurous, and another could be highly agreeable and trustworthy, thus, potentially complementing each other’s particular strengths associated with startup success.

The benefits of larger and more personality-diverse foundation teams can be seen in the apparent differences between successful and unsuccessful firms based on their combined Big Five personality team footprints, as illustrated in Fig.  2 B. Here, maximum values for each Big Five trait of a startup’s co-founders are mapped; stratified by successful and non-successful companies. Founder teams of successful startups tend to score higher on Openness, Conscientiousness, Extraversion, and Agreeableness.

When examining the combinations of founders with different personality types, we find that some ensembles of personalities were significantly correlated with greater chances of startup success—while controlling for other variables in the model—as shown in Fig.  2 C (for more details on the modelling, the predictive performance and the coefficient estimates of the final model, see Extended Data Figures  19 , 20 , and 21 in SI section  A.6 ).

Three combinations of trio-founder companies were more than twice as likely to succeed than other combinations, namely teams with (1) a Leader and two Developers , (2) an Operator and two Developers , and (3) an Expert/Engineer , Leader and Developer . To illustrate the potential mechanisms on how personality traits might influence the success of startups, we provide some examples of well-known, successful startup founders and their characteristic personality traits in Extended Data Figure  22 .

Startups are one of the key mechanisms for brilliant ideas to become solutions to some of the world’s most challenging economic and social problems. Examples include the Google search algorithm, disability technology startup Fingerwork’s touchscreen technology that became the basis of the Apple iPhone, or the Biontech mRNA technology that powered Pfizer’s COVID-19 vaccine.

We have shown that founders’ personalities and the combination of personalities in the founding team of a startup have a material and significant impact on its likelihood of success. We have also shown that successful startup founders’ personality traits are significantly different from those of successful employees—so much so that a simple predictor can be trained to distinguish between employees and entrepreneurs with more than 80% accuracy using personality trait data alone.

Just as occupation-personality maps derived from data can provide career guidance tools, so too can data on successful entrepreneurs’ personality traits help people decide whether becoming a founder may be a good choice for them.

We have learnt through this research that there is not one type of ideal ’entrepreneurial’ personality but six different types. Many successful startups have multiple co-founders with a combination of these different personality types.

To a large extent, founding a startup is a team sport; therefore, diversity and complementarity of personalities matter in the foundation team. It has an outsized impact on the company’s likelihood of success. While all startups are high risk, the risk becomes lower with more founders, particularly if they have distinct personality traits.

Our work demonstrates the benefits of personality diversity among the founding team of startups. Greater awareness of this novel form of diversity may help create more resilient startups capable of more significant innovation and impact.

The data-driven research approach presented here comes with certain methodological limitations. The principal data sources of this study—Crunchbase and Twitter—are extensive and comprehensive, but there are characterised by some known and likely sample biases.

Crunchbase is the principal public chronicle of venture capital funding. So, there is some likely sample bias toward: (1) Startup companies that are funded externally: self-funded or bootstrapped companies are less likely to be represented in Crunchbase; (2) technology companies, as that is Crunchbase’s roots; (3) multi-founder companies; (4) male founders: while the representation of female founders is now double that of the mid-2000s, women still represent less than 25% of the sample; (5) companies that succeed: companies that fail, especially those that fail early, are likely to be less represented in the data.

Samples were also limited to those founders who are active on Twitter, which adds additional selection biases. For example, Twitter users typically are younger, more educated and have a higher median income 47 . Another limitation of our approach is the potentially biased presentation of a person’s digital identity on social media, which is the basis for identifying personality traits. For example, recent research suggests that the language and emotional tone used by entrepreneurs in social media can be affected by events such as business failure 48 , which might complicate the personality trait inference.

In addition to sampling biases within the data, there are also significant historical biases in startup culture. For many aspects of the entrepreneurship ecosystem, women, for example, are at a disadvantage 49 . Male-founded companies have historically dominated most startup ecosystems worldwide, representing the majority of founders and the overwhelming majority of venture capital investors. As a result, startups with women have historically attracted significantly fewer funds 50 , in part due to the male bias among venture investors, although this is now changing, albeit slowly 51 .

The research presented here provides quantitative evidence for the relevance of personality types and the diversity of personalities in startups. At the same time, it brings up other questions on how personality traits are related to other factors associated with success, such as:

Will the recent growing focus on promoting and investing in female founders change the nature, composition and dynamics of startups and their personalities leading to a more diverse personality landscape in startups?

Will the growth of startups outside of the United States change what success looks like to investors and hence the role of different personality traits and their association to diverse success metrics?

Many of today’s most renowned entrepreneurs are either Baby Boomers (such as Gates, Branson, Bloomberg) or Generation Xers (such as Benioff, Cannon-Brookes, Musk). However, as we can see, personality is both a predictor and driver of success in entrepreneurship. Will generation-wide differences in personality and outlook affect startups and their success?

Moreover, the findings shown here have natural extensions and applications beyond startups, such as for new projects within large established companies. While not technically startups, many large enterprises and industries such as construction, engineering and the film industry rely on forming new project-based, cross-functional teams that are often new ventures and share many characteristics of startups.

There is also potential for extending this research in other settings in government, NGOs, and within the research community. In scientific research, for example, team diversity in terms of age, ethnicity and gender has been shown to be predictive of impact, and personality diversity may be another critical dimension 52 .

Another extension of the study could investigate the development of the language used by startup founders on social media over time. Such an extension could investigate whether the language (and inferred psychological characteristics) change as the entrepreneurs’ ventures go through major business events such as foundation, funding, or exit.

Overall, this study demonstrates, first, that startup founders have significantly different personalities than employees. Secondly, besides firm-level factors, which are known to influence firm success, we show that a range of founder-level factors, notably the character traits of its founders, significantly impact a startup’s likelihood of success. Lastly, we looked at team-level factors. We discovered in a multifactor analysis that personality-diverse teams have the most considerable impact on the probability of a startup’s success, underlining the importance of personality diversity as a relevant factor of team performance and success.

Data sources

Entrepreneurs dataset.

Data about the founders of startups were collected from Crunchbase (Table  2 ), an open reference platform for business information about private and public companies, primarily early-stage startups. It is one of the largest and most comprehensive data sets of its kind and has been used in over 100 peer-reviewed research articles about economic and managerial research.

Crunchbase contains data on over two million companies - mainly startup companies and the companies who partner with them, acquire them and invest in them, as well as profiles on well over one million individuals active in the entrepreneurial ecosystem worldwide from over 200 countries and spans. Crunchbase started in the technology startup space, and it now covers all sectors, specifically focusing on entrepreneurship, investment and high-growth companies.

While Crunchbase contains data on over one million individuals in the entrepreneurial ecosystem, some are not entrepreneurs or startup founders but play other roles, such as investors, lawyers or executives at companies that acquire startups. To create a subset of only entrepreneurs, we selected a subset of 32,732 who self-identify as founders and co-founders (by job title) and who are also publicly active on the social media platform Twitter. We also removed those who also are venture capitalists to distinguish between investors and founders.

We selected founders active on Twitter to be able to use natural language processing to infer their Big Five personality features using an open-vocabulary approach shown to be accurate in the previous research by analysing users’ unstructured text, such as Twitter posts in our case. For this project, as with previous research 20 , we employed a commercial service, IBM Watson Personality Insight, to infer personality facets. This service provides raw scores and percentile scores of Big Five Domains (Openness, Conscientiousness, Extraversion, Agreeableness and Emotional Stability) and the corresponding 30 subdomains or facets. In addition, the public content of Twitter posts was collected, and there are 32,732 profiles that each had enough Twitter posts (more than 150 words) to get relatively accurate personality scores (less than 12.7% Average Mean Absolute Error).

The entrepreneurs’ dataset is analysed in combination with other data about the companies they founded to explore questions about the nature and patterns of personality traits of entrepreneurs and the relationships between these patterns and company success.

For the multifactor analysis, we further filtered the data in several preparatory steps for the success prediction modelling (for more details, see SI section  A.5 ). In particular, we removed data points with missing values (Extended Data Fig.  13 ) and kept only companies in the data that were founded from 1990 onward to ensure consistency with previous research 32 (see Extended Data Fig.  14 ). After cleaning, filtering and pre-processing the data, we ended up with data from 25,214 founders who founded 21,187 startup companies to be used in the multifactor analysis. Of those, 3442 startups in the data were successful, 2362 in the first seven years after they were founded (see Extended Data Figure  15 for more details).

Entrepreneurs and employees dataset

To investigate whether startup founders show personality traits that are similar or different from the population at large (i. e. the entrepreneurs vs employees sub-analysis shown in Fig.  1 A and B), we filtered the entrepreneurs’ data further: we reduced the sample to those founders of companies, which attracted more than US$100k in investment to create a reference set of successful entrepreneurs (n \(=\) 4400).

To create a control group of employees who are not also entrepreneurs or very unlikely to be of have been entrepreneurs, we leveraged the fact that while some occupational titles like CEO, CTO and Public Speaker are commonly shared by founders and co-founders, some others such as Cashier , Zoologist and Detective very rarely co-occur seem to be founders or co-founders. To illustrate, many company founders also adopt regular occupation titles such as CEO or CTO. Many founders will be Founder and CEO or Co-founder and CTO. While founders are often CEOs or CTOs, the reverse is not necessarily true, as many CEOs are professional executives that were not involved in the establishment or ownership of the firm.

Using data from LinkedIn, we created an Entrepreneurial Occupation Index (EOI) based on the ratio of entrepreneurs for each of the 624 occupations used in a previous study of occupation-personality fit 44 . It was calculated based on the percentage of all people working in the occupation from LinkedIn compared to those who shared the title Founder or Co-founder (See SI section  A.2 for more details). A reference set of employees (n=6685) was then selected across the 112 different occupations with the lowest propensity for entrepreneurship (less than 0.5% EOI) from a large corpus of Twitter users with known occupations, which is also drawn from the previous occupational-personality fit study 44 .

These two data sets were used to test whether it may be possible to distinguish successful entrepreneurs from successful employees based on the different patterns of personality traits alone.

Hierarchical clustering

We applied several clustering techniques and tests to the personality vectors of the entrepreneurs’ data set to determine if there are natural clusters and, if so, how many are the optimum number.

Firstly, to determine if there is a natural typology to founder personalities, we applied the Hopkins statistic—a statistical test we used to answer whether the entrepreneurs’ dataset contains inherent clusters. It measures the clustering tendency based on the ratio of the sum of distances of real points within a sample of the entrepreneurs’ dataset to their nearest neighbours and the sum of distances of randomly selected artificial points from a simulated uniform distribution to their nearest neighbours in the real entrepreneurs’ dataset. The ratio measures the difference between the entrepreneurs’ data distribution and the simulated uniform distribution, which tests the randomness of the data. The range of Hopkins statistics is from 0 to 1. The scores are close to 0, 0.5 and 1, respectively, indicating whether the dataset is uniformly distributed, randomly distributed or highly clustered.

To cluster the founders by personality facets, we used Agglomerative Hierarchical Clustering (AHC)—a bottom-up approach that treats an individual data point as a singleton cluster and then iteratively merges pairs of clusters until all data points are included in the single big collection. Ward’s linkage method is used to choose the pair of groups for minimising the increase in the within-cluster variance after combining. AHC was widely applied to clustering analysis since a tree hierarchy output is more informative and interpretable than K-means. Dendrograms were used to visualise the hierarchy to provide the perspective of the optimal number of clusters. The heights of the dendrogram represent the distance between groups, with lower heights representing more similar groups of observations. A horizontal line through the dendrogram was drawn to distinguish the number of significantly different clusters with higher heights. However, as it is not possible to determine the optimum number of clusters from the dendrogram, we applied other clustering performance metrics to analyse the optimal number of groups.

A range of Clustering performance metrics were used to help determine the optimal number of clusters in the dataset after an apparent clustering tendency was confirmed. The following metrics were implemented to evaluate the differences between within-cluster and between-cluster distances comprehensively: Dunn Index, Calinski-Harabasz Index, Davies-Bouldin Index and Silhouette Index. The Dunn Index measures the ratio of the minimum inter-cluster separation and the maximum intra-cluster diameter. At the same time, the Calinski-Harabasz Index improves the measurement of the Dunn Index by calculating the ratio of the average sum of squared dispersion of inter-cluster and intra-cluster. The Davies-Bouldin Index simplifies the process by treating each cluster individually. It compares the sum of the average distance among intra-cluster data points to the cluster centre of two separate groups with the distance between their centre points. Finally, the Silhouette Index is the overall average of the silhouette coefficients for each sample. The coefficient measures the similarity of the data point to its cluster compared with the other groups. Higher scores of the Dunn, Calinski-Harabasz and Silhouette Index and a lower score of the Davies-Bouldin Index indicate better clustering configuration.

Classification modelling

Classification algorithms.

To obtain a comprehensive and robust conclusion in the analysis predicting whether a given set of personality traits corresponds to an entrepreneur or an employee, we explored the following classifiers: Naïve Bayes, Elastic Net regularisation, Support Vector Machine, Random Forest, Gradient Boosting and Stacked Ensemble. The Naïve Bayes classifier is a probabilistic algorithm based on Bayes’ theorem with assumptions of independent features and equiprobable classes. Compared with other more complex classifiers, it saves computing time for large datasets and performs better if the assumptions hold. However, in the real world, those assumptions are generally violated. Elastic Net regularisation combines the penalties of Lasso and Ridge to regularise the Logistic classifier. It eliminates the limitation of multicollinearity in the Lasso method and improves the limitation of feature selection in the Ridge method. Even though Elastic Net is as simple as the Naïve Bayes classifier, it is more time-consuming. The Support Vector Machine (SVM) aims to find the ideal line or hyperplane to separate successful entrepreneurs and employees in this study. The dividing line can be non-linear based on a non-linear kernel, such as the Radial Basis Function Kernel. Therefore, it performs well on high-dimensional data while the ’right’ kernel selection needs to be tuned. Random Forest (RF) and Gradient Boosting Trees (GBT) are ensembles of decision trees. All trees are trained independently and simultaneously in RF, while a new tree is trained each time and corrected by previously trained trees in GBT. RF is a more robust and straightforward model since it does not have many hyperparameters to tune. GBT optimises the objective function and learns a more accurate model since there is a successive learning and correction process. Stacked Ensemble combines all existing classifiers through a Logistic Regression. Better than bagging with only variance reduction and boosting with only bias reduction, the ensemble leverages the benefit of model diversity with both lower variance and bias. All the above classification algorithms distinguish successful entrepreneurs and employees based on the personality matrix.

Evaluation metrics

A range of evaluation metrics comprehensively explains the performance of a classification prediction. The most straightforward metric is accuracy, which measures the overall portion of correct predictions. It will mislead the performance of an imbalanced dataset. The F1 score is better than accuracy by combining precision and recall and considering the False Negatives and False Positives. Specificity measures the proportion of detecting the true negative rate that correctly identifies employees, while Positive Predictive Value (PPV) calculates the probability of accurately predicting successful entrepreneurs. Area Under the Receiver Operating Characteristic Curve (AUROC) determines the capability of the algorithm to distinguish between successful entrepreneurs and employees. A higher value means the classifier performs better on separating the classes.

Feature importance

To further understand and interpret the classifier, it is critical to identify variables with significant predictive power on the target. Feature importance of tree-based models measures Gini importance scores for all predictors, which evaluate the overall impact of the model after cutting off the specific feature. The measurements consider all interactions among features. However, it does not provide insights into the directions of impacts since the importance only indicates the ability to distinguish different classes.

Statistical analysis

T-test, Cohen’s D and two-sample Kolmogorov-Smirnov test are introduced to explore how the mean values and distributions of personality facets between entrepreneurs and employees differ. The T-test is applied to determine whether the mean of personality facets of two group samples are significantly different from one another or not. The facets with significant differences detected by the hypothesis testing are critical to separate the two groups. Cohen’s d is to measure the effect size of the results of the previous t-test, which is the ratio of the mean difference to the pooled standard deviation. A larger Cohen’s d score indicates that the mean difference is greater than the variability of the whole sample. Moreover, it is interesting to check whether the two groups’ personality facets’ probability distributions are from the same distribution through the two-sample Kolmogorov-Smirnov test. There is no assumption about the distributions, but the test is sensitive to deviations near the centre rather than the tail.

Privacy and ethics

The focus of this research is to provide high-level insights about groups of startups, founders and types of founder teams rather than on specific individuals or companies. While we used unit record data from the publicly available data of company profiles from Crunchbase , we removed all identifiers from the underlying data on individual companies and founders and generated aggregate results, which formed the basis for our analysis and conclusions.

Data availability

A dataset which includes only aggregated statistics about the success of startups and the factors that influence is released as part of this research. Underlying data for all figures and the code to reproduce them are available on GitHub: https://github.com/Braesemann/FounderPersonalities .
