Mom Test

Helps you run customer interviews that don't mislead you by forcing focus on past behavior instead of hypotheticals. When someone says "would you buy this?" you're getting politeness, not data. This applies the three core rules: talk about their life not your idea, ask about specifics in the past, and talk less. It scores your interview questions 0-10 and tells you exactly what to fix. Use it when validating ideas, interpreting wishy-washy feedback, or writing interview scripts. The question patterns and good versus bad examples are immediately usable. Pairs with jobs-to-be-done for deeper problem understanding.

The Mom Test Framework

Framework for customer conversations that won't lead you astray, based on a fundamental truth: everyone is lying to you -- not maliciously, but because you're asking the wrong questions. 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. Talk about their problems, their lives, and their existing behavior instead of pitching, and ask about specifics in the past, not hypotheticals about the future. Above all, talk less and listen more.
