Why Everyone Lies

Have you ever pitched an idea and everyone said it was great, only to find no one actually bought it?

Lesson 1 of the Wondering course The Mom Test

The Pitch Everyone Loved

You share your business idea. Friends nod, coworkers smile, and even a stranger says it sounds great.

Then you launch. Nobody buys.

Praise during the pitch versus no buyers at launch

Notice how the same idea gets smiles and thumbs up on the left but zero buyers on the right: praise and purchases are different signals.

This happens all the time, and bad luck is not the cause. The people you asked gave you misleading positive feedback.

This lesson explains why everyone lies a little when you ask about your idea, and why their approval cannot predict whether your business will work.

Lies Born From Kindness

People do not lie to you out of malice.

They want to be supportive. They want to avoid conflict. They do not want to hurt your feelings.

Three kind motives, one misleading answer
  • Polite lie: Praise driven by manners, not your idea.
  • Be supportive: They want to encourage you.
  • Avoid conflict: Criticism could make things awkward.
  • Spare feelings: They do not want to hurt you.

These are good intentions. Social norms favor encouragement over brutal honesty, so a kind fib feels like the right thing to say.

The result is a polite lie: praise that says more about manners than about your idea.

The Question That Traps Them

Asking "Is my idea good?" seems harmless. For the listener, it is a trap.

You are asking them to judge something you clearly care about. That puts them in an uncomfortable position.

In that moment, the socially acceptable response is encouragement.

So they say what keeps the conversation pleasant. You walk away feeling validated, holding feedback that is fundamentally flawed.

How a polite lie forms
  • You ask: You ask someone if your idea is good.
  • They feel stuck: Judging something you care about feels uncomfortable.
  • Norms pull: The socially acceptable response is encouragement.
  • They encourage: They say what keeps the conversation pleasant.
  • False validation: You leave confident, with flawed feedback.

Friends, Family, and Strangers

The politeness instinct is so strong that even strangers will tell you your idea sounds great.

They would rather be polite than tell you it will not work.

Friends and family are even worse sources. They genuinely want you to succeed and care about your feelings, so the pull toward encouragement gets stronger.

Who gives the least useful feedback?
  • Strangers
  • Friends and family

Closer relationships mean kinder, less useful answers.

Do Not Blame the Liars

It is tempting to feel betrayed when praise turns out to be empty. That reaction misses the real cause.

You cannot blame them for lying. You asked the wrong question, one that invites a polite response.

Who is responsible for the lie?

The advice is blunt: you should not ask anyone if your business is a good idea. It is a bad question, and everyone will lie to you at least a little.

The fix starts with how you ask.

Only the Market Knows

Approval feels like evidence, but it predicts very little.

Individual opinions, even sincere ones, are worthless for predicting whether your business will succeed.

Only the market truly knows if your business will work: whether people actually buy.

Two kinds of feedback
  • Opinions
  • The market

"Only the market knows. Everything else is just opinion and hallucination."

Remember the pitch everyone loved? The praise was opinion. The empty sales were the market speaking.

Spotting Polite Lies in Your Work

Watch for praise that arrives right after you ask someone to judge your idea.

A friend who says "I love it" is showing kindness. A stranger who says "sounds great" is being polite. Neither is giving you market data.

Read the signal correctly

Stop asking whether your business is a good idea.

Treat every opinion as opinion, and let the market be the judge.

Check yourself

When people praise a business idea they secretly doubt, they are usually motivated by _____

  • a wish to be supportive
  • a wish to mislead you

Answer: a wish to be supportive

People don't lie out of malice. Social norms push them to be supportive, avoid conflict, and spare your feelings, so encouragement feels like the acceptable response.

Whether a business will work is decided by the _____, while what friends and strangers say about it is just _____.

Answer: Whether a business will work is decided by the market, while what friends and strangers say about it is just opinion.

Only the market truly knows if a business will succeed. Everything else, including approval from others, is just opinion and cannot predict success.

Maya wants honest feedback on her startup idea. Which group is the WORST source for validating it?

  • Her close friends and family
  • Strangers she meets at a café
  • Customers deciding whether to buy
  • People who have never heard of her

Answer: Her close friends and family

Friends and family genuinely want you to succeed and care about your feelings, so they are the most likely to give encouraging rather than honest answers.
