Customer Interview Script That Gets Real Insights
People will tell you your idea is great. They will not tell you they’d never actually pay for it. The Mom Test methodology solves this by shifting from hypothetical questions (“would you buy this?”) to behavioral questions (“tell me about the last time you tried to solve this”). This recipe generates the exact script to run those conversations.
The Recipe
Act as a user research expert specializing in "The Mom Test" methodology. I need a customer interview script that prevents people from lying to me out of politeness and instead extracts raw, unbiased data about their actual behavior.
My target customer is: [INSERT TARGET AUDIENCE].
The problem I think they have is: [INSERT ASSUMED PROBLEM].
Draft a structured interview flow including:
- The Hook: How to frame the conversation so they know I'm not trying to pitch them anything.
- The Golden Questions: Five open-ended questions that focus strictly on how they currently solve this problem, their past actions, and where they have actually spent money trying to fix it.
- Red Flag Deflectors: Teach me how to steer the conversation back to reality if they start giving hypothetical compliments like "I would definitely buy that!"
Provide the exact word-for-word script I can use to run these interviews seamlessly.
Why hypothetical questions kill research
| Bad question | Why it fails | Better version |
|---|---|---|
| ”Would you use this?” | People say yes to be polite | ”What do you currently do when this happens?" |
| "How much would you pay?” | Hypothetical pricing is meaningless | ”Have you paid for anything to solve this? What?" |
| "Do you find this frustrating?” | Leading; they’ll agree | ”Walk me through the last time this happened.” |
The golden rule: ask about the past, not the future. Past behavior is data. Future intention is flattery.
The Mom Test in one sentence
Don’t talk about your idea. Talk about their life. If they’d tell the same things to your mom without embarrassing you, the questions are good.
Red flag phrases to listen for
These signal you’re getting polished answers, not honest ones:
- “I would definitely use that”
- “That sounds really interesting”
- “I think a lot of people would want this”
When you hear these, redirect: “That’s great to hear — can you tell me about the last time you actually tried to solve this problem?”
🔁 Leftover Remixes
🌶️ Spicy: “I ran 5 interviews and everyone said they loved it but no one signed up for the waitlist. Help me figure out what I’m not asking or what signal I’m misreading.”
🧊 Mild: “Give me just the 5 golden questions for [audience + problem] — no script, just the questions.”
💰 Budget: “What’s the single most important question to ask a potential customer to find out if this problem is actually painful enough to pay to solve?”
