The key ideas in The Mom Test

Three rules

Talk about their life instead of your idea. Ask about specific things that happened in the past, rather than opinions about the future. Talk less and listen more. People are poor at predicting what they'll do, and much better at telling you what they did.

Compliments are fool's gold

Fitzpatrick calls compliments the fool's gold of customer learning, because they feel like progress and aren't. Deflect them politely and steer back to facts, such as how the person deals with the problem today.

Anchor the fluff

It sounds like data and isn't.

Leave with a commitment

A good conversation ends with the other person giving something up, like their time, their reputation or their money. That might be a second meeting, an introduction to their boss, or a pre-order. If all you got were compliments, Fitzpatrick counts the meeting as a failure, however good it felt.

Lines worth underlining

  1. Everyone lies

    Ask your mum if your idea is good and she'll lie to be kind. So stop asking that.

  2. Their life

    Ask about their life and their problems, and leave your idea out of it.

  3. The past

    Ask what they did last time. Opinions about the future are only guesses.

  4. Compliments

    Compliments are worthless as data. Steer the talk back to facts.

  5. Commitment

    A good meeting ends with them giving something up, such as their time, their reputation or money.

A story from the book

Mum and the cookbook app

Fitzpatrick opens with a son asking his mum about his idea, a cookbook app for the iPad. She says it sounds lovely and she'd use it. She means well, and it tells him nothing. The book then replays the chat with questions about her actual cooking.

One thing to try

Ask about the last time

Find one person who has the problem your idea solves. Don't mention the idea. Ask them to talk you through the last time it happened, what it cost them and what they've already tried. Write down what they did, and ignore what they say they'd do.
