The False Positive Trap
Most customer interviews are fundamentally flawed. When you pitch your idea to a friend or potential customer, their social conditioning forces them to be “supportive.” They say, “That sounds amazing!” or “I’d definitely use that.”
In startup land, these are polite lies. They feel like signal, but they are noise. Rob Fitzpatrick’s The Mom Test posits that you should never even mention your idea during an initial validation interview. The moment you do, the data is poisoned by social etiquette.
“The world’s most dangerous phrase is: ‘Everyone I talked to said it was a great idea.’”
Asking About the Past, Not the Future
Humans are notoriously bad at predicting their future behavior. If you ask someone if they will go to the gym next week, they say yes. If you ask how many times they went last week, you get the truth.
To build for truth, your questions must be grounded in concrete past actions. Instead of asking about features, ask about the last time they faced the problem. How did they solve it? How much did it cost? Who authorized the payment?
Noise (The Pitch)
“Do you think a tool that automates your invoicing would be helpful?”
Signal (The Search)
“Talk me through the last time you sent an invoice. What tools did you use?”
Building for Truth
The ultimate goal of validation isn't to prove you're right; it's to find the truth as quickly as possible—even if that truth is that your idea is worthless. Truth-seeking requires clinical detachment from your solution. You are a detective investigating a crime scene, not a salesperson trying to move units.
