How to write a discussion chapter
The difference between results and discussion, a reliable structure, and how to make claims your data can support.
9 min read · Reviewed 2026 · Written and reviewed by Chris McGarrigle
Results report what you found. The discussion explains what it means, why it might be so, how it sits against the literature, and what follows. Merging the two is the most common structural error at this stage.
This is the chapter where marks are won, because it is where your own analytical voice is most visible.
A structure that works
Organise the discussion by finding, not by data collection instrument.
- Restate the key finding in one sentence.
- Interpret it: what is the most plausible explanation?
- Compare: which studies does this agree with, and which does it contradict?
- Explain the divergence: context, sample, method, timing.
- State the implication for practice, policy or theory.
Calibrate your claims
Match the strength of your language to the strength of your evidence. 'This suggests', 'is consistent with' and 'indicates' are usually accurate. 'Proves' almost never is. Overclaiming is punished more heavily than modest, well-evidenced conclusions.
Limitations, then future research
State limitations specifically — this sample, this instrument, this timeframe — and say what each one means for interpretation. Then propose future research that follows directly from those limitations rather than a generic call for 'more studies'.
Common mistakes
- Introducing new data in the discussion.
- Repeating the results chapter with different sentence order.
- Discussing only findings that support your expectations.
- Generic limitations that could appear in any dissertation.
Try this: Five sentences per finding
- List your three or four main findings.
- For each, write the five sentences from the structure above.
- Underline every claim verb and check the evidence supports it.
- Expand each set into a section.

Check that findings, objectives and question still line up.

- What goes in a discussion chapter?
- Interpretation, not repetition: what your findings mean, how they agree or conflict with the literature you reviewed, what they contribute, what limits them, and what should follow.
- How is the discussion different from the findings chapter?
- Findings report what the data show. The discussion explains why that matters and puts it back into conversation with the literature.
- How do I discuss results that contradict the literature?
- Treat contradiction as a contribution. Explain plausible reasons — different population, context, timing or method — rather than apologising for the result.
