A journal article reporting empirical research is most often organised according to the IMRaD structure — Introduction, Methods, Results, and Discussion — a standardised arrangement that lets readers locate any part of the argument quickly and lets the work be evaluated and reproduced. Wrapped around this core are the abstract, the references and the metadata that make the article discoverable and citable.
This guide walks through each component, explaining what it contains, how to read it efficiently and how to write it well.
The abstract: the article in miniature
The abstract is a concise summary, usually a single paragraph, that states the question, the approach, the key findings and their significance. It is the most-read part of any paper and is what appears in databases and search results, so it must stand alone. When reading, start here to decide whether the full paper is relevant; when writing, draft it last, once the rest of the article is settled.
Introduction: why the work matters
The Introduction sets the context, reviews relevant prior work, identifies the gap or problem the study addresses, and states the research question or hypothesis. A common and effective shape is a funnel: from the broad field, to the specific gap, to the precise aim of this study. Readers use it to understand motivation; writers should make the contribution and its novelty explicit by the end of the section.
Methods: how it was done
The Methods section describes the materials, participants, procedures and analyses in enough detail that a competent peer could reproduce the study. This section is the backbone of reproducibility and is scrutinised closely during peer review. When reading critically, this is where you judge whether the conclusions are actually supported; when writing, prioritise completeness and precision over narrative flair, and cite data and code where they are deposited.
Results: what was found
The Results section presents the findings — figures, tables and statistics — without interpretation. The discipline of separating results from their interpretation is what keeps the evidence distinguishable from the argument built upon it. Readers should compare the results against the stated aims; writers should report findings neutrally and let the Discussion do the interpretive work.
Discussion: what it means
The Discussion interprets the results, relates them back to the original question and the prior literature, acknowledges limitations, and considers implications and future directions. A frequently used shape mirrors the Introduction in reverse: from the specific findings outward to their broader meaning. This is where authors make their case, and where readers weigh whether the interpretation is justified by the evidence in Results.
| Section | Question it answers | Read it to… |
|---|---|---|
| Abstract | What is this, in brief? | Decide relevance |
| Introduction | Why does it matter? | Understand motivation |
| Methods | How was it done? | Judge rigour and reproducibility |
| Results | What was found? | See the evidence |
| Discussion | What does it mean? | Weigh the interpretation |
References and metadata
The references list the sources cited, anchoring the work in the existing literature and enabling citation indexing — the very links that systems such as Web of Science record. Surrounding the article is its metadata: title, authors, affiliations, the journal’s ISSN, and persistent identifiers. Most published articles carry a DOI that makes them permanently citable and resolvable, while author identifiers such as ORCID and organisation identifiers such as ROR — part of the wider PID stack — disambiguate who and where.
Authorship and contribution are increasingly recorded with the CRediT taxonomy, which assigns standardised roles to each contributor. Guidance on preparing manuscripts is available on our for-authors page, and definitions of the structural terms used here appear in the CASRAI dictionary.
Beyond IMRaD
IMRaD is the dominant pattern for empirical reports, particularly in the sciences, but it is not universal. Review articles, theoretical papers and humanities scholarship often use different structures. Even so, the underlying logic — context, approach, evidence, interpretation — tends to persist in some form, which is why understanding IMRaD helps in reading almost any scholarly article.
Frequently asked questions
What does IMRaD stand for?
IMRaD stands for Introduction, Methods, Results, and Discussion — the four core sections of a typical empirical research article, usually preceded by an abstract and followed by references.
In what order should I write the sections?
Many writers draft Methods and Results first, since they are most concrete, then the Discussion and Introduction, and finally the abstract once everything else is fixed. Reading order and writing order need not match.
Why are Results and Discussion kept separate?
Separating them keeps the evidence (Results) distinct from its interpretation (Discussion), so readers can evaluate the findings independently of the authors’ conclusions about what those findings mean.
Do all journal articles follow IMRaD?
No. IMRaD suits empirical studies, especially in the sciences, but reviews, theoretical pieces and humanities work often use other structures. The IMRaD logic, however, frequently underlies them in adapted form.
