The Mom Test – 3 Lies That Kill Startups

Beware of These 3 False Positives

Hi Reader,

💡 Today’s Niblit:The Mom Test” exposes the three most dangerous types of misleading feedback that fool entrepreneurs into building the wrong products:

  1. Empty compliments
  2. Fluffy generalizations
  3. Misdirecting feature requests

Learning to spot and navigate these traps can save your startup from a costly journey in the wrong direction.

🔑 Key Insight: Bad data comes in three deceptive flavors that seem helpful but aren’t.

  • Compliments cost nothing to give and tell you nothing useful.
  • Generic statements (“I always,” “I never,” “I would”) are unreliable predictions about future behavior.
  • Feature requests often mask deeper problems that need exploring.

Think of customer feedback like fool’s gold — it can glitter and excite you, but building your business on it leads nowhere. Just as a prospector needs to learn the difference between real gold and pyrite, entrepreneurs must learn to distinguish between valuable insights and misleading signals.

This matters because false positives are more dangerous than rejection. They convince you to over-invest time and money in the wrong direction, while negative feedback helps you correct course early.

🦉 Nibble of Wisdom: The most dangerous feedback isn’t negative — it’s falsely positive.

🛠️ Practical Tip: When someone says “I would definitely buy that,” ask what they’re currently spending money on to solve this problem.

🚀 Quick Action: Review your most recent customer conversation notes. Highlight every compliment, “would/could” statement, and feature request. Now look at what concrete facts remain — that’s your real data.

🔍 Further Exploration:

  • Learn how preference falsification affects market research
  • Examine your own buying behavior versus what you tell entrepreneurs you “would” buy
  • Consider how response bias might be affecting your customer research

🎬 Wrapup: Remember, your goal isn’t to collect compliments — it’s to discover truths that will make your business succeed.
