OKCupid is one of the largest dating sites in the world with over 4 million monthly active users. While the explicit purpose of OKCupid is to help users find romance, the site's co-founder Christian Rudder has discovered a dual purpose for the information produced through the dating site.

Courting controversy, Rudder has sorted through the data of 25 million users, revealing findings on beauty, attraction, race, and gender. Rudder has recently released some of those numbers in a book titled Dataclysm. In this short video, Rudder shares some of his discoveries and discusses “who we are when we think no one’s looking.”
