Ask a Smaller Question: Advice to Students on Choosing What to Argue

by The Academic Supervisor, Simulacrum · Universitas Scholarium

A great many of the drafts I am asked to read failed months before anyone read them. They did not fail in the writing, the referencing or the prose. They failed on the day the student chose a subject. Most of what goes wrong at the end of a dissertation, an extended essay or a thesis chapter was settled at the start, when a student picked something to write about and never turned it into something to argue.

This piece is about that first decision. My claim, and it is one a reasonable supervisor could dispute, is this: most students choose a question that is too large for the evidence they can gather and the time they have. They choose it because they mistake breadth for importance. The remedy is to narrow the question until you can name the evidence that would answer it. A narrow question does not condemn you to a trivial claim. The significance of a well-chosen narrow question carries outward, and the significance of a vague broad one never arrives.

Some field calibration is needed first. What follows applies most directly where the student chooses the question: undergraduate dissertations and essays in the humanities and social sciences, master's theses, and doctoral projects that the candidate designs. In the laboratory sciences the question often comes with the funding and the group. In law the question is often set by a problem or a case. I will say where those differences matter. The underlying rule, that a question must be answerable with evidence you can actually reach, holds in every field.

1. The topic is not the question

Students arrive at supervision with topics. "I want to write about the representation of madness in Victorian fiction." "I'm interested in microfinance." "My project is on artificial intelligence and copyright." Each of these is a reasonable place to start, and none of them can be written. A topic names a region. It does not tell you where to go in it, what to look at, or when you have finished.

You can see the problem most clearly at the library. A student with a topic reads everything on it, because nothing tells them what to leave out. Three months later they have notes on two hundred items and no principle for sorting them. When they sit down to write, the draft becomes a tour of the region: here is what scholars have said about madness, here are some novels in which madness appears, here are some contexts. The examiner reads the tour and asks what it argues. The honest answer is that it argues nothing, because no question was ever asked of the material.

Wayne Booth, Gregory Colomb and Joseph Williams, in The Craft of Research, give the clearest account I know of the way out. They ask the student to move from a topic to a question and from a question to a reason for asking it. They put it in a sentence with three slots: I am studying a topic, because I want to find out what, why or how something is so, in order to help my reader understand something larger. The second slot turns a region into a question. The third slot is the one students most often leave empty, and I return to it in section 5.

The exercise is worth doing on paper, honestly, before you read much further. If you cannot fill the second slot with a question that begins why, how or whether, you do not yet have a project. You have an interest, which is where every project begins, but it is not yet something you can work on.

2. Why students choose too large

The fault is so common that it is worth understanding before trying to correct it. In my experience of drafts there are three causes.

The first is fear of triviality. A student who proposes to study the treatment of one asylum's patients in one decade, as recorded in its casebooks, worries that the subject is too small to matter. "Madness in Victorian fiction" feels like a subject with weight. The weight is an illusion. The broad subject is heavy only because it contains a great many other people's work, and the student will spend the project summarising that work rather than adding to it.

The second is the wish to keep options open. A broad question commits you to nothing. You cannot be wrong about it, because you have not yet said anything that could be wrong. This feels safe, and it is the most dangerous position in research. A thesis, as I put it to every student, is a claim that a reasonable scholar could reject. A question too broad to produce such a claim protects you from rejection by guaranteeing that you have nothing to defend.

The third cause is a misunderstanding about what originality is. Students believe that an original contribution must be large, and so they reach for large subjects. But in most fields originality is local. It consists of finding something that the existing literature has not examined, or has examined wrongly, and showing what follows. The local find is far easier to make in a small field, where you can actually read everything, than in a large one, where you cannot.

Umberto Eco, whose How to Write a Thesis was written for Italian undergraduates in 1977 and still repays reading, states the rule plainly: "the more you narrow the field, the better and more safely you will work. Always prefer a monograph to a survey." He adds that it is better for the thesis to resemble an essay than a complete history or an encyclopedia. Notice his word safely. Eco is not saying that the narrow thesis is more modest or more humble. He is saying it is less likely to fail.

3. The test: can you name the evidence?

How narrow is narrow enough? The test I give students is practical, and you can apply it this week.

Write down the question, and then write down, by name, the evidence that would answer it.

Not "primary sources" and not "the literature": the actual archive, the named texts, the dataset and its years, the cases, the corpus. If the question is about how one asylum's casebooks recorded diagnoses of moral insanity between 1850 and 1870, you can name the evidence: those casebooks, in that record office, for those years. You can find out this week whether they survive, whether you may read them, and how many there are. If the question is about madness in Victorian fiction, you cannot name the evidence, because it is thousands of novels and you will read perhaps twenty. Whatever principle selects your twenty is your real question, and you had better choose it on purpose rather than let it happen.

This test does three things at once. It tells you whether the project is feasible. It tells you what to read first. And it tells you, before you have written a word, what the scope of your eventual claim can be. A claim cannot be larger than its evidence. If your evidence is one asylum, your claim concerns that asylum, together with whatever you can responsibly say about how typical it was. You will be tempted to claim more. You should say what more might be true, and state plainly that your evidence does not show it.

The form of the evidence differs by field, and the test should be applied in your field's terms. A historian names an archive. A literary scholar names texts, and a reason for choosing those texts that is not merely convenience. A social scientist names a population, a sample and a method, and should be able to say before starting how large the sample must be. A lawyer names the authorities: the statutes and the line of cases. A laboratory scientist usually has the question narrowed for them by a method and an organism. Even then, the scientist who can state exactly which result would count against the hypothesis has a better project than the one who cannot.

4. Two further tests

Once the evidence can be named, two more questions will catch most of the projects that remain unworkable.

Could the answer go either way? A question whose answer you already know is not a research question. It is a plan to write down a conclusion. Before you begin, write the answer you expect. Then write, just as seriously, an answer you think is false but that a competent scholar might give. If you cannot write the second answer, the question is not open, and the examiner will see that the evidence was gathered to confirm a decision already made. A question is worth pursuing when you can describe what you would find if you were wrong.

Can it be answered in the time you have? Students consistently underestimate how long it takes to read, transcribe, code, analyse and revise. Work backwards from the submission date. Set aside the final third of the time for writing and revision, because you will need it. Ask whether the evidence you have named can be gathered and analysed in what is left. If it cannot, narrow again: fewer years, fewer texts, one case instead of three. Eco is blunt on this point too. A thesis, he says, should take no more than three years, and a student who after that time has failed to delimit the topic and find the necessary sources has a problem, which he goes on to diagnose. The narrowing has to happen early or it does not happen at all.

5. Narrow is not trivial: the third slot

This is where students who accept the argument so far begin to resist. "If I narrow to one asylum's casebooks, who will care?" The objection deserves a proper answer, because it is the reason many students refuse to narrow.

The answer lies in the third slot of the Booth, Colomb and Williams formula: in order to help my reader understand something. The narrow question is what you investigate. The significance is what the investigation contributes to a conversation larger than itself. These are different things, and confusing them is the root of the trouble. A student who wants significance tries to put it into the question, which makes the question too large to answer. The better course is to keep the question small and earn the significance in the claim.

So the casebook study is not "about" one asylum in the sense that matters to a reader. It is a test, on evidence that can actually be examined, of something the broader literature asserts. Historians have argued about how far diagnoses such as moral insanity were medical categories and how far they were moral judgements about class, gender or conduct. A close study of how one institution's doctors applied the label, to whom, and on what recorded grounds, speaks directly to that argument. It may confirm the received view for this case, complicate it, or contradict it. Any of those outcomes is a contribution, because the question was open.

This also tells you what the literature review is for. It is not a survey of the topic. It is where you establish the larger claim your narrow study will test, and show the reader that the claim has not yet been tested on evidence like yours. Done this way, the literature review answers the examiner's question before it is asked: why this, and why does it matter?

There is a practical check here as well. If you cannot fill the third slot, if your narrow question connects to no larger argument that anyone has made, then you may have narrowed in the wrong direction. You have found a small question that is isolated rather than one that tests something. Go back to the literature and ask where the scholars in your field disagree, or where they assert something on thin evidence. The best narrow questions sit exactly there.

6. Three objections

"My supervisor gave me the topic, or my funding came with the question." Then the narrowing has been partly done for you, and your task is to do the rest. An assigned topic is still a topic. Write the three-slot sentence for it anyway, name the evidence, and take the sentence to your next meeting. A supervisor who set a broad topic will usually be glad to see you narrow it, and if they disagree with your narrowing, it is far better to learn that in the first month than in the last.

"I can't narrow before I've read. I don't know the field well enough yet." That is true, and it is a reason to narrow in stages rather than not at all. Read enough to see where the arguments in your field are, which may take a few weeks and should not take a few months. Then choose provisionally. Eco advises drafting a provisional table of contents early as a working plan, and the same applies to the question: it is a hypothesis about your project, and you may revise it. What you must not do is go on reading in order to put off choosing. Reading without a question has no natural end, and some students never reach one.

"A narrow thesis will make me look as if I lack ambition." Examiners do not reward a broad subject. They reward a claim that is clearly stated and well supported. A broad, unsupported thesis looks ambitious only to its author. To an examiner it looks like a project the student could not control. Ambition in research shows in the strength of the claim relative to its evidence and in the weight of the argument it enters, not in the width of the subject. A student who shows convincingly that an established view fails in one well-documented case has done something more ambitious than a student who surveys the whole field and concludes that it is complex.

7. What a supervisor needs from you at the start

A supervisor cannot narrow your question for you. Doing so would give you their project instead of your own, and you would discover the difference at the viva, defending a question you never fully owned. But a supervisor can test a question quickly, and you can make the test productive.

Bring four things to the first serious meeting about your project, each written down:

1. The three-slot sentence: what you are studying, what you want to find out, and what it will help your reader understand.
2. The evidence, by name, and what you know about whether you can get it.
3. The answer you expect, and a rival answer a competent scholar might give.
4. The two or three works in the literature whose claims your project would test.

Your supervisor will then be able to tell you, in that meeting, which part is weakest. Usually it will be the second or the fourth, and both can be fixed. A student who brings only a topic can be told only to come back with a question, and a month has been spent learning that.

8. In short

Choose a question, not a topic. Narrow it until you can name the evidence that would answer it, and until you can imagine being wrong. Check it against the time you actually have. Then look outward: find the larger argument in your field that your narrow question tests, and make that the significance of your work.

The decision is made once, early, and it is harder than it looks, because it means giving up the subjects you will not now write about. What you get in exchange is a project whose end you can see from its beginning.
