The Decision Process, In Order
- Check the assignment brief. Most instructors state the required style explicitly in the prompt or rubric. This is the single most reliable source — always check here first.
- Check the course syllabus. Many courses set a default style for all assignments at the start of the term, even if individual prompts don't repeat it.
- Check your department's style guide. Departments — especially nursing, psychology, history, and English — often publish an official department-wide citation policy on their website.
- Look at what your field publishes in. If you're mimicking a journal article format, the journal's "Instructions for Authors" page names its required style.
- Ask your instructor. If none of the above gives a clear answer, a quick email is faster and safer than guessing — submitting in the wrong style is an unforced formatting error that's entirely avoidable.
Why Different Fields Use Different Styles
Citation styles weren't designed arbitrarily — each reflects what matters most to the way a field communicates:
- Sciences and social sciences prioritize recency, since research can be superseded quickly — author-date systems put the year front and center.
- Humanities prioritize precise textual location, since arguments often hinge on exact wording — author-page systems (MLA) embed the page number in every citation.
- History and the arts prioritize source provenance and nuance, which often needs more space than a parenthetical citation allows — footnote systems (Chicago NB) let writers add explanatory commentary in the note itself.
- Medicine and engineering prioritize uncluttered prose when citing dozens of sources — numeric systems (Vancouver, IEEE) keep the in-text marker to a single number.
- Law prioritizes exhaustive sourcing and precedent-tracing — footnote-heavy systems (Bluebook, OSCOLA) allow extensive citation chains.

| Discipline | Typical style | Notes |
|---|---|---|
| Psychology | APA 7 | APA was originally developed for psychology journals |
| Nursing & health sciences | APA 7 | Some clinical/medical programs use AMA or Vancouver instead |
| Education | APA 7 | Consistent across most education programs |
| Sociology | ASA or APA | ASA for sociology-specific journals, APA in mixed social science programs |
| Business & economics | APA 7 or Harvard | Varies heavily by institution and country |
| English literature | MLA 9 | The default across nearly all literature and composition courses |
| Linguistics & foreign languages | MLA 9 | Some linguistics programs use APA instead — check your department |
| History | Chicago Notes-Bibliography | The standard across nearly all history departments |
| Art history & philosophy | Chicago NB or MLA | Varies by program; Chicago is more common |
| Political science | Chicago AD or APSA | APSA is a Chicago Author-Date variant specific to the discipline |
| Medicine (clinical) | AMA or Vancouver | AMA dominates US journals; Vancouver is the international medical standard |
| Engineering & computer science | IEEE | Near-universal in technical and engineering coursework |
| Chemistry | ACS | American Chemical Society's own numeric style |
| Biology & life sciences | CSE | Council of Science Editors offers both numeric and author-date variants |
| Law (US) | Bluebook | Footnote-based, highly specific to legal citation |
| Law (UK/Commonwealth) | OSCOLA | The standard for UK and Commonwealth legal writing |
Remember that this table reflects common conventions, not universal rules — a specific professor or program can require a different style than what's typical for the field. The brief or syllabus always overrides general convention.
What If Your Paper Spans Multiple Disciplines?
Interdisciplinary papers (a nursing capstone that draws on policy and ethics literature, for example) still use a single citation style throughout — the discipline of the course or assignment determines the style, not the discipline of each individual source you cite. A psychology paper that cites a historical source still formats that source in APA, not Chicago.
Frequently Asked Questions
What if my syllabus and my professor's verbal instructions conflict?
Ask for clarification in writing (email) so you have a record of which instruction to follow — written instructions issued later generally supersede the syllabus default, but it's worth confirming rather than assuming.
Can I use whatever style I'm most comfortable with if none is specified?
Only as a last resort after trying to find guidance. Submitting in a style your field doesn't typically use can read as not understanding your discipline's conventions, even if the formatting itself is technically correct.
Does the citation style affect my grade if the content is otherwise excellent?
Yes, in most rubrics — formatting and citation accuracy are typically a distinct grading category, separate from content and argument quality.
Switch Styles Without the Stress
Bibloq formats your sources in whichever style your discipline requires — and lets you switch instantly if requirements change.
