Christian Rudder analyzed the behavior of users on OkCupid, the dating site he cofounded, on both the company’s blog and in his book, Dataclysm. He reported that Black women receive 25 percent fewer first messages than women of other races. And when Black women reach out to men first, they receive responses 25 percent less often than women of other races. Asian men contend with similar behavior. Rudder found that white, Black, and Latina women rate Asian men as 30 percent less attractive than they rate men of other races.
