“Very intelligent people are actually less satisfied with their lives if they socialize with people more frequently. Those with more intelligence and the capacity to use it are less likely to spend so much time socializing because they are focused on some other longer term objective.

Think of the really smart people you know. They may include a doctor trying to cure cancer or a writer working on the great American novel or a human rights lawyer working to protect the most vulnerable people in society. To the extent that frequent social interaction detracts from the pursuit of these goals, it may negatively affect their overall satisfaction with life.”
