The Mom Test Framework

Framework for having useful customer conversations that won't lead you astray. Based on a fundamental truth: everyone is lying to you -- not because they're malicious, but because you're asking the wrong questions. Your mom will tell you your idea is great because she loves you. Investors, friends, and even potential customers will do the same. The Mom Test provides rules for asking questions so good that even your mom can't lie to you.

Core Principle

Good customer conversations are about their life, not your idea. The moment you mention what you're building, people switch from sharing truth to performing politeness. They tell you what you want to hear. The antidote is simple: talk about their problems, their lives, and their existing behavior instead of pitching your solution. Ask about specifics in the past, not hypotheticals about the future. And above all, talk less and listen more.

Scoring

Goal: 10/10. When reviewing or planning customer conversations, rate them 0-10 based on adherence to the principles below. A 10/10 means questions focus entirely on the customer's life and past behavior, with no leading, no pitching, and clear commitment signals; lower scores indicate gaps to address. Always provide the current score and specific improvements needed to reach 10/10.

Framework Sections

1. The Mom Test Rules

Core concept: Three simple rules that, when followed, make it impossible for even your most supportive loved ones to give you false validation. The rules shift conversations from opinion-gathering to fact-finding.

Why it works: Opinions are worthless because people are unreliable predictors of their own future behavior. Past behavior is the only reliable data. By focusing on what people have actually done rather than what they say they would do, you extract facts that can genuinely inform product decisions.
