Being a manager is not just about intelligence. It’s also about personality, about being the kind of person who wants to and likes to help other people, about being the kind of person who can make many many decisions quickly and delegate and do boring but necessary administrative work. Many brilliant people are not good at delegating or don’t particularly like to spend time doing mundane things or are not good at hiring or not good at judging good people from bad. If I am going to hire a manager, I want to see some experience at managing! General intelligence is not nearly enough.
