Most people rely on their gut instinct to decide how to date, who to marry, where to live, what career path to take, how to find happiness, but what if our gut is wrong? Biased, unpredictable, and misinformed, our gut, it turns out, is not all that reliable. Data from hundreds of thousands of dating profiles have revealed surprising successful strategies to get a date; data from hundreds of millions of tax records have uncovered the best places to raise children; data from millions of career trajectories have found previously unknown reasons why some rise to the top.

Hard facts and figures consistently contradict our instincts and demonstrate self-help that actually works — whether it involves the best time in life to start a business or how happy it actually makes us to skip a friend’s birthday party for a night of Netflix on the couch. From the boring careers that produce the most wealth, to the old-school, data-backed relationship advice so well-worn it’s become a literal joke, Stephens-Davidowitz unearths the startling conclusions that the right data can teach us about who we are and what will make our lives better.
