Good research notes are not miniature copies of the papers you read. Record what you will need later: the study's question, relevant evidence, limitations, your interpretation, and why the paper matters to your research.

Do not extract everything simply because it appears in the paper. Capture the study's question, context, design, sample or data, relevant measures or procedures, findings, limitations, and why the study matters to your research.

Remembering a paper is less important than being able to recover why it mattered. Leave a compact retrieval trail that records its contribution, relevance to your work, key evidence, limitations, connections, and what you intended to do with it.

Reading the abstract first gives you useful orientation, but it also gives you the authors' interpretation before you inspect the evidence. The best reading order depends on whether you are screening a paper or critically evaluating its results.

The Discussion can clarify findings, but it also gives you the authors' interpretation of them. For critical reading, it can be useful to form a provisional interpretation of the results before comparing it with theirs.

Reading the conclusion first can frame your expectations before you inspect the evidence. That does not automatically make your interpretation biased, but it gives you a reason to check the authors' claims independently against the study's methods and results.

You do not need to read every supplementary file attached to every paper. Read it when information outside the main article could materially change your understanding, appraisal, reproduction, or use of the study.

A protocol can show what researchers intended to do before the final results were known. Comparing it with the published paper is especially useful when prespecification, methodological changes, outcome selection, or analytical flexibility could affect your interpretation.

A statistical analysis plan can show how researchers intended to analyze their data before the final results were interpreted. It becomes particularly useful when analytical flexibility, prespecification, or deviations could affect your appraisal.

Even an important paper rarely requires reading every item in its reference list. Follow the citations that carry consequential claims, define key methods, reveal competing evidence, or lead you to literature your own work depends on.

A very long paper does not have to be read word by word to be understood well. Map the paper first, decide what you need from it, then read the sections carrying the evidence and methodological details relevant to your purpose.

Before judging a study's findings, determine exactly what question its design and analysis were capable of answering. The stated aim is only the starting point.
Read Guide →
Some papers state their research question directly; others express it through objectives, hypotheses, or methods. Learn how to distinguish what authors explicitly asked from what you must reconstruct.
Read Guide →
The population described in a paper's introduction may be broader than the people who actually generated its evidence. Learn how to identify the study population precisely.

Sometimes the problem is not what a paper reports but what it leaves unclear. Identify which missing details actually prevent you from judging the evidence.
Read Guide →
The journal article is often only one part of a study's documentation. Learn when another source is necessary and what protocols, registries, supplements, and previous papers can actually tell you.
Read Guide →
A paper’s findings and the authors’ interpretation of those findings are related, but they are not the same thing. Learn how to reconstruct what the data actually showed before deciding what those results mean.
Read Guide →
The prose surrounding a statistical result can influence how strong, important, or certain it seems. Learn how to inspect the numbers first and then evaluate whether the authors’ narrative accurately represents them.
Read Guide →
Participant accounts and qualitative interpretations are connected, but they occupy different analytical levels. Learn how to trace themes and claims back to the evidence used to support them without treating quotations as self-interpreting facts.
Read Guide →
What the data show and what researchers conclude are not necessarily the same claim. Learn how to trace conclusions back to the evidence and identify the additional reasoning required to move from results to meaning.

Yes. An abstract can give a stronger, simpler, or more positive impression than the full results justify. Learn what gets lost in compression and how to check an abstract against the complete paper.
Read Guide →
Yes. A Discussion can make a weak, uncertain, or inconclusive finding sound more convincing than the underlying evidence warrants. Learn how to detect the interpretive moves that create that stronger impression.
Read Guide →
Yes. A conclusion can extend beyond the reported results by adding causal claims, mechanisms, broad generalizations, practical importance, or recommendations that the study did not adequately establish. Learn how to trace every major conclusion back to its evidential basis.

Failing to find convincing evidence of an effect is not necessarily evidence that the effect is absent. Learn how to distinguish an inconclusive result from evidence supporting no meaningful effect.
Read Guide →
Forming a provisional interpretation before reading the authors’ conclusion can help you see the evidence without immediately inheriting their framing. The goal is not to ignore the authors, but to compare two interpretations against the same study.
