Writing your thesis introduction and conclusion
The introduction and conclusion are the first and last pages a supervisor, and an examining committee, read closely — often the only ones read in full when time is short. And yet they're the worst-written parts of most theses, because the introduction is written too early and never revisited, and the conclusion is written in a hurry when the energy has run out.
The introduction: four things, in this order
An effective introduction does four jobs, usually in this sequence. First: it places the topic in context and says why it's relevant — what's at stake, who should care. Second: it states the research question explicitly, often in a stand-alone sentence. Third: it briefly explains the method — how the thesis will try to answer it. Fourth: it previews the structure, chapter by chapter, in a few lines.
Each of these jobs has a precise function for the reader: after the introduction, the supervisor should know exactly what to expect and by what criteria to judge it.
Write the introduction at the start, rewrite it at the end
A draft introduction at the start of the work is useful: it forces you to focus the question and the structure. But that draft describes the thesis you thought you'd write, not the one you wrote — and the two almost always diverge.
The final version of the introduction is written after finishing the chapters and the conclusion, when you actually know what the question was that you answered, which chapters are needed and which ones changed along the way. Rewriting it entirely at that point is normal, not a sign of having gone wrong earlier.
The conclusion is not a summary
The most common mistake in a conclusion is repeating what the chapters have already said, chapter by chapter, with phrases like "in the first chapter we saw that...". A supervisor has just read those chapters: they don't need a summary.
The conclusion does a different job: it returns to the research question posed in the introduction and gives it an explicit answer, based on what the chapters have shown. Then it says what the work adds — even modestly — to what was known before, and what stays open: the study's limitations, the questions that remain, the directions for future research.
Consistency between introduction and conclusion
The simplest test of a thesis's soundness is to place side by side the question posed in the introduction and the answer given in the conclusion, and check that they're talking about the same thing. If the opening question was about X and the conclusion answers about Y, either the question needs rephrasing (in the introduction, which gets rewritten at the end anyway) or the conclusion isn't answering what the work set out to do.
The study's limitations: stating them is a strength
Admitting the limitations — a small sample, a narrow period, a source you couldn't consult — doesn't weaken the thesis: it makes it more credible. A supervisor notices the limitations anyway; stating them first, clearly, shows you've understood them and that the conclusions take them into account. Hiding them makes it look like you didn't see them.
Keeping introduction, chapters and conclusion aligned
The practical problem is that the introduction, body and conclusion are written at different times, weeks apart, and end up not talking to each other: the introduction promises a chapter you later cut, the conclusion answers an earlier version of the question. Having the work's chapter-and-section structure in front of you as you write, with the research question noted where it's needed, helps keep the three parts consistent. In NovLore the structure lives in the same place as the text, and the AI assistant stays optional: you can use it to check whether the conclusion answers the introduction's question, or work without it.
Frequently asked questions
How long should the introduction and conclusion be?
There's no universal rule, but a common guideline is between 5 and 10% of the total length each, with the introduction sometimes a little longer than the conclusion. Content matters more than length: if the introduction does its four jobs and the conclusion answers the question, the exact proportion is secondary.
Can I write the conclusion before finishing all the chapters?
You can draft it, but the final version needs the chapters to be complete: the conclusion is based on what the chapters have actually shown, and until a chapter is finished you don't know for certain what it demonstrated.
In the conclusion, can I propose future developments even if I won't carry them out?
Yes, it's an expected part of a thesis conclusion. Pointing to the questions that remain open and the possible directions for later research shows you have a view of the field beyond your specific work, and it's something committees appreciate.
