What it's about
Everybody Lies argues that people routinely mislead pollsters, surveys, and even themselves about sex, prejudice, and other sensitive behavior, but their anonymous searches on Google and other platforms reveal what they actually think and do. Drawing on billions of search queries, Stephens-Davidowitz treats this data as a new kind of confession booth, using it to measure hidden racism, closeted sexuality, and parental bias, while also showing where big data's predictive power breaks down without careful causal reasoning.

What’s inside
- 1The Confession Problem1 min
Self-reported survey data is systematically unreliable because people misrepresent sensitive behavior to pollsters and to themselves.
- 2Digital Truth Serum1 min
Anonymous Google searches function as a more honest data source than surveys because searchers have no audience to perform for.
- 3Hidden Racism in Search Data1 min
Geographic patterns in racist search terms predicted anti-Obama voting better than any survey measure of racial attitudes.
- 4The Closet, Measured1 min
Search and behavioral data suggest a meaningfully larger closeted gay population than surveys capture, and its size varies with local tolerance.
- 5Biased Parents, Unfiltered1 min
Parents' private search behavior reveals gender bias about their children's intelligence and appearance that they would not admit on a survey.
- 6Beyond Google1 min
Other digital platforms beyond search, including forums, adult sites, and dating services, provide behavioral data that Google alone cannot supply.
- 7When Correlation Fails1 min
Big data's apparent predictive power collapses without theoretical grounding, as shown by Google Flu Trends' well-documented failure.
- 8From Correlation to Causation1 min
Raw correlational patterns in big data are not enough for decision-making; they require experiments or natural experiments to establish cause and effect.
- 9Predicting the Unpredictable1 min
Behavioral datasets can anticipate harmful or economically significant events earlier than official statistics, when built and tested carefully.
