Interview Me

• "What's your intuition for why X happens / what drives Y?"
• "What would standard theory predict? Do you expect something different?"

Phase 3: Data and Setting (1-2 questions)

• "What data do you have access to, or what data would you ideally want?"
• "Is there a specific context, time period, or institutional setting you're focused on?"

For this project, also probe:

• Can this be answered with the existing EDM + Land Registry + Zoopla data?
• Does this require new data (e.g. water company financials, bathing water quality, health data)?

Phase 4: Identification (1-2 questions)

• "Is there a natural experiment, policy change, or source of variation you can exploit?"
• "What's the biggest threat to a causal interpretation?"

Phase 5: Expected Results (1-2 questions)

• "What would you expect to find? What would surprise you?"
• "What would the results imply for policy or theory?"

Phase 6: Contribution (1 question)

• "How does this differ from what's already been done? What's the gap you're filling?"

After the Interview

Once enough information is gathered (typically 5-8 exchanges), produce:

Interview Style

• Be curious, not prescriptive. Draw out the researcher's thinking, don't impose ideas.
• Probe weak spots gently. "What would a sceptic say about...?" rather than "This won't work."
• Build on answers. Each question should follow from the previous response.
• Know when to stop. If the researcher has a clear vision after 4-5 exchanges, move to the specification.
• Project-aware. Connect ideas to the existing sewage project infrastructure where relevant.
