Big data. Baseball managers use it to win pennants. Stockbrokers use it to beat the market. And now you can use it to get what you really want in life. That's according to a new book by Seth Stephens-Davidowitz called Don't Trust Your Gut.

The smarter move, Seth says, is to comb through millions of data points to find statistically significant answers. But who has time for that, not to mention the technical know-how? Well, Seth does. And this week on the show, he'll share the answers he found, starting with the surprising traits you should look for when searching for your soulmate.
