Golf’s brainiest player would like you to know he is no genius. Bryson DeChambeau took a four-hour IQ test not long ago, for a company he works with called Neuropeak, and he scored 121—above average, certainly, but not Mensa material. Sure, the man they call the Scientist talks excitedly about air density and wind vectors, spreads the gospel of single-length irons, and once said he would decide whether to pull the pin on putts based on the coefficient restitution of the flagstick. But that’s passion, not genius. Despite how he acts sometimes, DeChambeau does not always think he is the smartest person in the room.
