Everybody
Lies

The internet is the largest confession booth ever built. Surveys capture who people want to be. Search data catches what people are afraid to admit.

The Private RecordVol. 01

What people type when nobody is watching.

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

Stop asking what people say they want. Ask what they actually did last week, last month, or last time — behavior over survey answers.

I'll do this
05

Question the clean chart

When a tidy chart appears, ask: What is missing, who is excluded, and what incentive shaped this number?

I'll do this
03

Look for the shame gap

Where people feel judged, stated preferences diverge from private behavior. Name one topic where shame likely distorts the data.

I'll do this
08

Check one claim against behavior

Take one stated preference today and compare it to recent actions.

I'll do this
04

Build a tiny revealed-preference audit

For one personal or work decision, list what you claim to value vs what your calendar, spending, and searches show.

I'll do this
09

Spot one shame-gap topic

Notice one place where people (or you) might be lying by omission and ask a better behavioral question.

I'll do this
07

Use private truth gently

If you discover an uncomfortable truth about yourself or others, act with care — insight without cruelty.

I'll do this
06

Find the weird proxy

Pick one hard-to-measure truth and invent a proxy signal — searches, skips, returns, late-night messages — that might reveal it.

I'll do this
The truth is not always what people say in public. It is often what they search for in private.
