If the Results section is where you report what happened, the Discussion is where you say what it means — and it is where many otherwise-solid papers stumble. The most common failure is simple: the authors just restate their results in words, adding no interpretation. A good discussion does something harder and more valuable. It takes your findings, places them in the wider conversation, and tells the reader what they should now think.
Interpret, don't repeat
The cardinal rule: the Discussion interprets; it does not re-report. Your reader already saw the numbers in the Results. Here, you explain what those numbers imply — whether they support your hypothesis, what mechanism might explain them, and how confident the reader should be. If a sentence in your Discussion could sit unchanged in your Results, it is in the wrong section.
A structure that works
Most strong discussions follow the same arc, from specific to broad:
- Lead with your key finding. Open the Discussion by stating, in plain words, the most important thing you found and whether it answered your question.
- Place it in the literature. How does it agree with, extend, or contradict previous work? Engage honestly with studies that disagree — do not cite only the ones that support you.
- Offer an explanation. Why might you have found this? Propose a mechanism or interpretation, and be clear about how speculative it is.
- State the limitations. Name the boundaries of what you can conclude (see writing a limitations section).
- Say what it means. The implications for practice, policy or future research — concrete, not "more research is needed".
Common mistakes
- Overreaching. Claiming more than your data support is the fastest way to lose a reviewer. Match the strength of your claim to the strength of your evidence.
- Ignoring contrary evidence. If prior studies disagree with you, address them. Pretending they do not exist reads as either ignorance or spin.
- The mini-review. The Discussion is not a literature survey. Cite what is relevant to your finding, not everything in the field.
End on a clear conclusion
Finish with a short paragraph that answers the question you started with — one or two sentences on what you found and why it matters, without hedging or new information. A reader who read only your first finding and your last paragraph should come away knowing exactly what your paper contributes.
