High IQ seems to bring out arrogance in people. They are always smarter and know better than you. They start to believe that since they are tops in one domain they can be the best at everything. It's impossible to be good at everything. Working with one person like this is a pain. Now imagine everyone you work with having the same attitude. The work output will be less than ideal since every one will be an expert at everything. Nothing will get done. Read about Robert McNamara the secretary of defense during a great part of the Vietnam war. By all accounts he was a genius. Yet, he could not manage the war. He was an outstanding numbers man by any measure. His expertise did not carry to managing a war. He is just one example.
