No, you tell me, as you are the one expressing an opinion. Opinions of intelligence are normally based upon observations of behavior. You tell me what behaviors inform your opinion of the intelligence of baseball management. I don't think that baseball management needs any special kind of cognitive ability but they do need to understand the sport and how to evaluate talent. Just like an auto mechanic needs to understand the mechanical workings of an automobile. We all tend to have specialized knowledge of the jobs we do which has little to do with general intelligence and more to do with experience, interests, and to some extent with natural inclinations and abilities that lend themselves to the jobs we do. What kind of abilities do you think are required to succeed in management in baseball?
