A new book that looks at Google search data will unveil some of the secret fantasies that we keep hidden from the rest of the world. Don't worry though, Everybody Lies by Seth Stephens-Davidowitz isn't going to expose you personally, but will reveal the online habits of Earth as a whole. As Seth puts it "Google is a digital truth serum" so what exactly does the search engine tell us about ourselves? Unsurprisingly, sex or porn is the ideal way to get a larger understanding of society in general. Speaking to Vox , Seth explains:. I don't understand how social scientists weren't begging PornHub for their data.
