Google remembers every search anyone does. If you combine all that data in the right ways, you can come up with a lot of results, theories and conclusions. That’s what Seth Stephens-Davidowitz does in this book. The title comes from one of his conclusions: people say they do things (in surveys and so on) but the aggregated search data from Google shows that a large number of them are lying. It’s a clever idea and he draws out a lot of interesting material (enough to fill a book!). If you’ve ever typed “why does my cat” into Google just to see what suggestions pop up, then this book is for you.
