Everybody Lies was published by
HarperCollins in 2017. The book has received several reviews and other coverage, was a
New York Times bestseller, and was named a book of the year by both
PBS NewsHour and
the Economist. The overriding theme of the book is that people aren't as honest about their true natures when responding to standard questionnaires as they are when searching the internet, on the assumption that search is a private activity. Of particular note is the empirical chapter,
Chapter 4: Digital Truth Serum, derived from extensive Big Data analysis of search engine search histories (primarily Google's) on sensitive subject matters such as prejudice, violence, and sexuality. The remainder of the book addresses the surrounding issues of methodology, epistemology, and moral philosophy. In 2022, Stephens-Davidowitz published another book, ''Don't Trust Your Gut: Using Data to Get What You Really Want in Life''. ==References==
