You know the feeling. You have a subject you genuinely care about, a folder of half-read articles and a loose picture of the essay in your head. Then someone asks, “So, what’s your research question?” and the picture goes blurry.
The question shapes almost every decision that follows: what you read, what evidence you use and what kind of argument you can make. Get it right early and everything else gets easier.
You have 4,000 words. That is not much room. Go too broad and you skim ten ideas without arguing any of them. Go too narrow and you end up with three sources and nothing to say.
The aim is enough substance to investigate, with clear edges to keep you focused.
What the Extended Essay is really asking
The Extended Essay is an independent research project. It is not a report, and it is not a tour of everything you have read. Examiners want a reasoned answer built on evidence.
Take climate change. Sea levels, farming, wildlife, health and energy use could each fill an essay on their own. Try to cover several and you will examine none of them properly.
Now narrow it: how did summer rainfall relate to wheat yields in one region over a set period? Suddenly there is a relationship to test, data to look for and explanations to weigh.
The same thinking works everywhere. In English, ask how a novelist uses narrative perspective to shape our view of power. In History, compare the significance of two causes of one event.
A good question gives your reading a purpose. Once you know what you are trying to establish, it gets easier to spot which material earns its place and which is just interesting noise.
Why sensible-sounding questions still fail
If you have ever searched for IB Diploma help UK hoping someone would simply fix your question, you will know most advice stays general. The problem usually runs deeper than wording.
Some questions sound perfectly reasonable and still produce only description. “Why did the French Revolution happen?” is the classic. You could fill pages with finances, inequality and politics without ever deciding what mattered most.
Compare it with “To what extent did financial problems contribute to the outbreak of the French Revolution?” Now you must make a judgement, which means weighing finance against other explanations rather than listing them.
Science has its own trap. “Does temperature affect plant growth?” feels simple until you try to design it. Which species? How will you measure growth? Which temperatures? What about light, water and soil?
Then there is access. You might want to study a company’s internal decisions, only to find the documents are not public.
None of this means dropping a topic you love. It means testing the question early. A question is only workable if the evidence you can realistically get gives you a fair chance of answering it.
Scope, evidence and purpose
Three ideas explain why some questions lead to stronger essays.
Scope is the boundary of your investigation: one novel, one period, one relationship between variables.
Evidence is what your answer rests on. That might be close readings of passages, contemporary documents set against historians’ views, or experimental measurements.
Analytical purpose is what you plan to establish with it: comparing explanations, evaluating significance, interpreting how meaning is made. The question should point you somewhere without deciding the answer in advance.
These must fit together. A narrow question with only one available source cannot support a real debate. Dozens of sources with a question that only asks “what happened” will never produce analysis.
Try finishing this sentence: “By examining this evidence, I want to establish whether, how or why…” If you cannot, go back to your interest and name the specific problem.
Three stress tests before you commit
Run these checks on any draft question.
1. The disagreement test. Can you imagine two credible answers that disagree with each other? If every sensible person would answer the same way, you have a fact-finding question, not an argument.
2. The preliminary source test. Give it a couple of days and gather a handful of sources: a few more for History, fewer for a lab-based Biology investigation. Label each as original evidence, interpretation or repetition. If most merely repeat the same claim, reconsider the question or widen the search.
3. The three-claims test. Write three claims you might make and note the evidence each one needs. Plausible claims with no way to support or challenge them reveal a weak question.
Narrowing in practice
Start broad, then name the relationship, problem or interpretation you want to investigate. The first version is for thinking, not for submitting.
- Broad: How does social media affect teenagers?
Focused: How was one political issue represented on one platform during a defined period? - Broad: What caused a revolution?
Focused: To what extent did one economic factor contribute to the outbreak of one revolution? - Broad: Does temperature affect plant growth?
Focused: How does a defined temperature range affect seed germination under controlled conditions?
Then sketch a simple argument plan. If a section does not help answer the question, ask whether it belongs.
Finally, use your supervisor meetings to discuss whether the question remains manageable, and record how your research decisions develop in line with the IB’s current guidance on reflection.
Mistakes worth avoiding
Over-narrowing. A very short period or unusual example can be precise but leave too little to analyse.
Choosing the answer first. Give contradicting sources the same attention as supporting ones. Contradictions often show the picture is more complicated, and a defensible conclusion says so.
Counting sources instead of weighing them. Several sources repeating the same claim may not be independent support. Check where their evidence comes from.
Clinging to a bad question. If the evidence no longer matches your wording, revise. The earlier you notice, the less you rewrite.
Where to go from here
Choosing a question is partly knowing what to leave out. The strongest question is not the most original-sounding. It is the one that lets you weigh evidence honestly and reach a conclusion you can justify.
