Adam Grant: Follow the evidence

"I'm amazed by the number of leaders who make decisions, especially about people, based on intuition instead of evidence. When I talk to leaders about this, the defense that usually comes up is, "I have this wealth of experience, and the reason I was put in this leadership role is to leverage that experience that no one else has."

My response is, "Well, I'm not saying you shouldn't learn from your experiences, I just want you to learn from people's experiences, too. That’s what data are."
