In this groundbreaking work, Seth Stephens-Davidowitz, a Harvard-trained economist, former Google data scientist, and New York Times writer, argues that much of what we thought about people has been dead wrong. The reason?  People lie, to friends, lovers, doctors, surveys—and themselves.

However, we no longer need to rely on what people tell us. New data from the internet—the traces of information that billions of people leave on Google, social media, dating, and even pornography sites—finally reveals the truth. By analyzing this digital goldmine, we can now learn what people really think, what they really want, and what they really do. Sometimes the new data will make you laugh out loud. Sometimes the new data will shock you.  Sometimes the new data will deeply disturb you.  But, always, this new data will make you think.

Everybody Lies combines the informed analysis of Nate Silver’s The Signal and the Noise, the storytelling of Malcolm Gladwell’s Outliers, and the wit and fun of Steven Levitt and Stephen Dubner’s Freakonomics in a book that will change the way you view the world. There is almost no limit to what can be learned about human nature from Big Data—provided, that is, you ask the right questions.


a whirlwind tour of the modern human psyche using search data as its guide ... The empirical findings in Everybody Lies are so intriguing that the book would be a page-turner even if it were structured as a mere laundry list. But Mr Stephens-Davidowitz also puts forward a deft argument: the web will revolutionise social science just as the microscope and telescope transformed the natural sciences.
