Writing the Discussion Section
Where findings are put into context and the reader is left to make up their own mind. Two stated purposes, one named risk — writing too much with too little substance — and the only treatment of the discussion section anywhere in six weeks of material.
Why the section exists at all
The opening clause is the whole architectural argument in one sentence. The discussion exists because the results section is forbidden to interpret. The two chapters are a single decision about where meaning is allowed to enter, split across two locations, and neither makes sense read alone.
That has a practical consequence worth acting on. If you find your discussion thin, the usual cause is not that you have nothing to say — it is that you have already said it in the results chapter, a sentence at a time, and there is nothing left to bring together. Writing the two chapters in order, and policing the boundary as you go, is what keeps the discussion from collapsing into a summary.
The two purposes, and the tension between them
Purpose 1 — put findings into context
- Against the literature you reviewed
- Against the research problem you set out to address
- Against the limits of your design
- Against what your field can actually apply
Purpose 2 — interpret so the reader can judge
- You supply the reading
- The reader retains the decision
- Which requires showing your reasoning, not only its conclusion
- And requires the evidence to remain visible under the interpretation
Too much with too little substance
The risk the source names is the correct one, and it is worth taking seriously because the discussion is the chapter where padding is easiest and least visible. Nobody pads a results table. Everybody can pad an interpretation.
What padding looks like in a discussion chapter
Restating the results
A paragraph that tells the reader what Table 3 showed, without saying anything about what it means. The results chapter already did this. If you cut the sentence and lose nothing, it was a restatement.
Reviewing the literature again
The discussion compares your findings to specific studies. It does not re-survey the field. The source is explicit about this in its fourth guideline.
Hedging every claim into nothing
"It may possibly be the case that some respondents might potentially have felt…" Four hedges on one claim means you do not believe it. Either make the claim with its actual confidence, or drop it.
Implications with no mechanism
"This has significant implications for practice" — for whom, doing what differently, on Monday? An implication that cannot be acted on is a sentence, not a finding.
The five guidelines, and the instruction to keep their order
The source supplies five numbered guidelines and instructs you to address them in the order presented. Each is treated in detail at the discussion guidelines; what matters here is the shape.
- Primary analyses
- Statistical significance
- Weaknesses and strengths
- The published literature
- Generalisability
WHAT EACH GUIDELINE ACTUALLY GIVES YOU
| Guideline | Content supplied |
|---|---|
| 1. Discuss the implications of the primary analyses first | A single line with nothing under it. "Primary analyses" is never defined anywhere in the supplied source. |
| 2. Discuss statistical significance | A definition and three parameters — sample size, variability, effect size — none with a threshold, a test or a procedure |
| 3. Discuss weaknesses and strengths | Three sentences. The most transferable passage in the week, and unillustrated |
| 4. Discuss the results against the published literature | Similarities and differences with other authors, and an explicit instruction to be selective |
| 5. Discuss generalisability | Dependent on study population, inclusion and exclusion criteria, and follow-up rate — all clinical-trial vocabulary, none defined |
The numbering is the source's own; the deck auto-numbers items 1 to 5 across three slides.
What this material was written for, and what you are using it for
A working structure
The source gives an order and no template. What follows is this library's construction from the five guidelines, offered as a starting shape rather than as a requirement.
Building the chapter
Open with the research problem, restated
One paragraph. The reader has been in a results chapter and needs the question back in view before the interpretation starts.
Take your principal findings in turn
For each: what you found, what you read it as meaning, and what else it could mean. The third part is what makes it a discussion rather than an assertion.
Set them against the literature
Specific studies, similarities and differences, and an attempt at why. Not a second literature review.
State the limitations honestly
Design weaknesses, collection problems, analysis and interpretation problems. Then say what you would do differently, which converts a weakness into a contribution.
Say how far it travels
What your findings apply to, and what they do not. Be specific about the boundary rather than gesturing at it.
Close into the conclusions
Limited to what your results support. The rules for this are at drawing conclusions from your results.
Getting it right
Before you call the chapter finished
- Every paragraph would change what a reader does, thinks, or rules out
- Nothing restates a result without adding a reading of it
- For each principal finding you have offered at least one alternative explanation and said why you prefer yours
- The literature comparison names specific studies rather than surveying the field
- Limitations are stated before someone else states them for you
- The generalisability claim is bounded, and the bound is specific
- If your study is qualitative, you have said where you departed from this guidance and why
What to carry forward
- The discussion exists because the results section is forbidden to interpret. If your discussion is thin, check whether you spent it in the results chapter.
- Interpretation that shows its working leaves the reader free to disagree on the evidence. That is what 'so the reader can make up their own mind' has to mean.
- Too much with too little substance is the right risk to name. Test every paragraph by what a reader could do differently having read it.
- Address the five guidelines in the order given — the source requires it and never says why. The order runs from inside the study outward, which is a defensible reading.
- This guidance was written for quantitative work. Three of the five guidelines transfer; one has no qualitative reading and one contradicts its own deck.
Frequently asked questions
How is the discussion different from the results?
The results report what you found; the discussion says what it means. The source is explicit that the second exists because the first is not permitted to interpret. Written properly they are one decision about where meaning enters, split across two chapters.
My discussion feels thin. What usually causes that?
Almost always that the interpretation was spent in the results chapter, a sentence at a time, leaving nothing to bring together. Policing the boundary while you write the results is what prevents it.
Do I have to follow the five guidelines in order?
The source instructs you to and gives no reason. The order runs from what you found, through your confidence in it, to its limits, to other work, to how far it travels — a defensible progression, though that reading is this library's rather than the source's.
Does this guidance work for a qualitative study?
Partly. Three of the five guidelines transfer almost unchanged. The statistical significance guideline has no qualitative reading, and the generalisability guideline contradicts an earlier slide in its own deck that describes qualitative work as emphasising transferability rather than generalisation.
How long should the discussion be?
The supplied material gives no length guidance for the discussion at all — not a range, a proportion or a worked case. The only quantity anywhere in the week is the word count on its own activity slide.
