Ask about specific past behavior instead of hypotheticals: use anchors like "tell me about the last time" and "walk me through what you did." Never mention your product or solution, and avoid any question whose answer is always yes.
The Mom Test is Rob Fitzpatrick's framework for customer conversations built on three rules: talk about their life not your idea, ask about specifics in the past, and talk less while listening more. It filters out compliments and opinions so only factual behavioral data remains.
Real validation requires a commitment costing time, reputation, or money, such as a pilot, an introduction, or a deposit. Compliments like "great idea" and hypothetical promises like "I would buy that" carry zero predictive value.
People are unreliable predictors of their own future behavior and answer hypotheticals to be polite. Asking "would you buy this?" costs them nothing, so instead ask what they currently spend and what they have already tried.
Stop when conversations converge: the last several interviews teach nothing new, the same problem repeats across customers, and you hold concrete commitments. Continuing past that point is procrastination, not research.
