01
Survey answers are performance
People edit themselves for status, politeness, fear, and memory. The lie is often automatic.
02
Searches are behavioral evidence
Private queries are not perfect truth, but they are closer to revealed demand than a polite questionnaire.
03
Small data can be powerful
The right weird dataset can expose motives that broad averages bury.

Method Notes
How to read the human dataset without becoming fooled by it.
Everybody Lies is not a sermon that all data is pure. It is a sharp editorial lesson: ask better questions, prize behavioral evidence, notice social desirability bias, and stay suspicious of tidy stories.
Ask what behavior records
Clicks, searches, purchases, and timestamps often reveal more than stated preferences.
Protect the weird data
The most valuable signal may be narrow, ugly, or embarrassing enough to be honest.
Do not worship scale
More data can magnify bad assumptions. Causality still needs careful thinking.
Use truth ethically
Seeing private behavior creates responsibility, not permission to exploit people.

Field Assignments
Action Steps
02
Replace one opinion question with behavior
When you want to understand someone, stop at least one "what do you think?" question and ask what action would reveal the same truth more reliably.
I'll do this
03
Look for the shame gap
Pick a topic where people have status reasons to lie: money, health, desire, bias, parenting, work. Compare the public story with private behavior.
I'll do this
04
Build a tiny revealed-preference audit
For one week, compare what you said mattered with your calendar, spending, searches, or screen time. Treat the mismatch as information, not guilt.
I'll do this
05
Question the clean chart
Before trusting a dashboard, ask what the data cannot see, who had incentive to distort it, and whether the proxy actually measures the claim.
I'll do this
06
Find the weird proxy
For a problem you care about, brainstorm five indirect signals that might reveal demand or fear better than a direct survey would.
I'll do this
07
Use private truth gently
If data reveals something painful about people, write down one way the insight could help them before writing down one way it could optimize against them.
I'll do this
The truth is not always what people say in public. It is often what they search for in private.
