Seth Stephens-Davidowitz is a Harvard-trained economist, a visiting lecturer at Wharton, a former Google data scientist and a writer for The New York Times on big data. Seth sat down to talk with Googler Megan Green about his new book, "Everybody Lies: Big Data, New Data, and What the Internet Reveals About Who We Really Are." In this book he explores the online data we leave behind every day, and what it reveals about our hidden feelings, desires, and fears; he explores topics ranging from Google searches about divorce peaking after Christmas, to whether Americans are more preoccupied with the intellectual potential of their sons or daughters.
