IMRaD: four sections, four questions, and the sentences that belong in each

IMRaD names the four-part structure of most empirical papers: Introduction, Methods, Results, and Discussion. Each part answers one question — why the study was done, how, what was found, and what it means — and content that belongs in one section is treated as a fault when it turns up in another.

Why it matters when you are writing

The structure exists to make papers skimmable in a consistent way. A reader assessing whether your work applies to their problem goes straight to Methods; one checking a claim goes to Results; one deciding whether to read at all reads the Introduction and the first paragraph of the Discussion. Honoring the boundaries is a courtesy to that reader, and violating them is the fastest way to look inexperienced.

The boundary that gets crossed most is Results and Discussion. Results reports what the data showed, without interpretation — “treatment scores exceeded control by 4.2 points.” Discussion says what it means, how it relates to prior work, and what its limits are. Putting “suggesting the intervention worked” into Results is the single most common reviewer comment on early-career manuscripts.

Fields vary the shape without abandoning it. Some journals merge Results and Discussion by agreement; qualitative work often uses Findings with interpretation woven through; theoretical papers do not use IMRaD at all. Follow the journal’s instructions to authors, and where they are silent, follow the structure of three recent papers you admire in that journal.

IN PRACTICE

The same study, one sentence per section

Introduction: hedging has not been linked to enforcement capacity. Methods: 4,200 provisions were coded and matched to agency data. Results: hedge density correlated with lower capacity (r = −0.41). Discussion: vagueness may reflect institutional limits, though the design cannot establish direction.

OFTEN CONFUSED WITH

What IMRaD is not

Abstract: The abstract summarizes all four IMRaD sections in one short passage; IMRaD is the structure of the paper itself.
Essay structure: An essay is organized by argumentative moves toward a thesis; IMRaD is organized by the stages of an empirical study.

Questions about imrad

Where do limitations go?

In the Discussion, usually near the end and before the conclusion. Stating them plainly is a strength; a reviewer who finds a limitation you did not mention trusts the rest less.

Can Results and Discussion be combined?

Some journals allow or prefer it, particularly for short reports. Check the instructions to authors — merging them when the journal expects them separate reads as a structural error.

What tense should each section use?

Broadly: present for established knowledge in the Introduction, past for what you did and found in Methods and Results, and present for what your findings mean in the Discussion.

Does IMRaD apply to qualitative research?

Often in adapted form, with Findings replacing Results and interpretation integrated. The underlying sequence — question, approach, what emerged, what it means — usually survives.

Abstract

An abstract condenses a paper into a standalone passage of roughly 150–300 words covering the problem, the method, the findings, and why they matter.

Signposting

Signposting is the language that tells readers where they are and where they are going: section previews, transitions that name the logical move, and sentences that state what has just been established.

Research question

A research question states, in one interrogative sentence, what a study exists to find out — narrow enough that you can say what evidence would answer it and what would not.

Hypothesis

A hypothesis predicts a specific relationship between variables in terms precise enough that data could contradict it.

Passive voice

The passive voice puts the thing acted on in the subject position — “the samples were incubated” — and lets you omit the actor entirely.
