How to write a conclusion paragraph
A conclusion paragraph closes a paper by restating its thesis, drawing the argument together and pointing to wider implications — without adding new evidence.
The step most authors miss
Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
Step by step
How to do it
1.Restate the thesis in fresh words
Reaffirm your central claim, but rephrase it rather than copying the introduction verbatim. The reader has now seen your evidence, so the restated thesis can carry more weight and precision than its first appearance.
2.Synthesise, don’t summarise
Draw your main points together to show how they combine to support the thesis, rather than listing them one by one. Synthesis explains what the argument adds up to; a flat summary just repeats what the reader has already read.
3.State the significance
Answer the “so what?” question: why does the argument matter? Point to its implications, applications or consequences — for the field, for practice, or for the wider issue — to give the reader a reason the paper was worth reading.
4.Look outward or forward
Where appropriate, widen the view: note limitations, suggest directions for further research, or connect the topic to a larger context. This reverses the introduction’s funnel, moving from your specific claim back out to the bigger picture.
5.Close cleanly without new material
End on a clear, resonant final sentence and resist adding new evidence, arguments or sources. Anything that needs support belongs in the body; the conclusion’s job is to consolidate, not to open a new line of thought.
What to avoid in a conclusion
Several habits weaken conclusions. The most damaging is introducing new evidence or a fresh argument: anything that needs support belongs in the body, and a new point raised at the end leaves the reader unsatisfied. Avoid signposting phrases such as “In conclusion” when the placement already makes the role obvious, and avoid simply restating the introduction word for word, which adds nothing. Equally, do not undercut your argument with apologetic hedging (“This is only my opinion and may be wrong”), and do not raise a doubt you cannot resolve. A good conclusion is confident, consolidating and brief — it earns its authority from the argument that precedes it.
Common questions
FAQ
Should a conclusion include new information?+
No. A conclusion should not introduce new evidence, arguments or sources. Its purpose is to consolidate what the paper has already established — restating the thesis, synthesising the main points and drawing out implications. Anything that requires support or explanation belongs in the body, where it can be developed properly.
How is a conclusion different from a summary?+
A summary simply restates the main points; a conclusion synthesises them, showing how they combine to support the thesis and what that means. A conclusion goes further than a summary by addressing significance — the “so what?” — and often by pointing to implications or further questions, whereas a summary stops at recapping content.
How long should a conclusion be?+
Keep it proportionate to the paper. A short essay usually needs a single conclusion paragraph; a longer research paper or dissertation may use a conclusion section with several paragraphs, sometimes separating findings, implications and future research. In all cases it should be tighter than the body — consolidating, not re-arguing, the work.
