>>The smartest people often find it difficult or impossible to work in teams. Same with introverts.<<

It is possible to buffer this a bit, but it requires skills many people do not have and might not wish to develop.

(Yes, hanging around and be emotionally supportive is work - it just happens to usually be women's work which adds a whole 'nother set of problems.)

...Also, this provides a plausible reason why a particular film character hates dealing with people (especially since they keep trying to bond by inventing him to boring extrovert stuff).
