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

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.

Do it in SuperDiss

Check that findings, objectives and question still line up.
