The New York Times reports that our ability to handle stress may be connected to a specific gene. Scientists discovered that the COMT gene determines the speed at which enzymes clear the hormone dopamine.

Those with fast-acting dopamine clearers are the Warriors, ready for threatening environments where maximum performance is required. Those with slow-acting dopamine clearers are the Worriers, capable of more complex planning. Over the course of evolution, both Warriors and Worriers were necessary for human tribes to survive.
This discovery changes the way we look at standardized test scores. Is it fair to only value the Warriors?
