Google searches are the digital truth serum because the search box feels private enough for confession.
Stephens-Davidowitz's central move is to compare public self-presentation with private behavior. The gap is where fear, desire, prejudice, loneliness, and demand become visible.
Surveys often measure what people are willing to say, not what they actually think or do.
Everybody Lies treats social desirability bias as a major measurement problem. People edit answers to sound kind, healthy, fair, happy, and in control.
The most revealing dataset may be narrow, strange, and embarrassing rather than large and polished.
The book's data-science lesson is not simply more data. It is better proxies: the behavioral traces that capture the thing people cannot or will not report directly.
