Worry too much? You might just be really smart. According to new research, worrying may have evolved along with high intelligence as a beneficial trait in humans.
"While excessive worry is generally seen as a negative trait and high intelligence as a positive one, worry may cause our species to avoid dangerous situations, regardless of how remote a possibility they may be," says researcher Jeremy Coplan, professor of psychiatry at Brooklyn's SUNY Downstate Medical Center. "In essence, worry may make people 'take no chances,' and such people may have higher survival rates. Thus, like intelligence, worry may confer a benefit upon the species."
In a small study published in the journal Frontiers in Evolutionary Neuroscience, 26 patients suffering from generalized anxiety disorder, and 18 volunteers in good mental health were examined. High levels of worry among the anxiety-plagued patients were linked to greater intelligence.
