Why the research question matters

1

The research question is the centre of your Extended Essay. A focused question makes it clear what you are arguing and helps you choose what to leave out.

2

A question that is too broad leads to a shallow essay, and one that is too narrow leaves little to discuss.

What a good question looks like

A good question is specific, open to analysis and answerable with sources you can reach. It asks for an argument, not a list of facts.

A step-by-step method

  1. Start with a broad area, read a few sources and note what puzzles you. Write the puzzle as a question, then test it: can you find evidence on both sides, and can you answer it within the word limit of 4,000?
  2. Revise the question after your first reading, since the best questions usually change.

Common mistakes

📘

Common mistakes are asking a yes or no question with no depth, choosing a topic with too few sources and changing the question late without updating the argument. Another is writing a question the essay never actually answers.

🎯

A tutor can test your question with you and suggest ways to sharpen it.
