““The people who perform best in normal conditions may not be the same people who perform best under stress,” Diamond says. People born with the fast-acting enzymes “actually need the stress to perform their best.” To them, the everyday is underwhelming; it doesn’t excite them enough to stimulate the sharpness of mind of which they are capable. They benefit from that surge in dopamine — it raises the level up to optimal. They are like Superman emerging from the phone booth in times of crisis; their abilities to concentrate and solve problems go up.
Some scholars have suggested that we are all Warriors or Worriers. 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.
In truth, because we all get one COMT gene from our father and one from our mother, about half of all people inherit one of each gene variation, so they have a mix of the enzymes and are somewhere in between the Warriors and the Worriers. About a quarter of people carry Warrior-only genes, and a quarter of people Worrier-only.
A number of research studies are looking at COMT, including several involving the American military. Researchers at Brown University have been studying COMT’s connection to post-traumatic stress disorder in veterans of the wars in Iraq and Afghanistan. Quinn Kennedy, a research psychologist at the Naval Postgraduate School, is studying how the gene correlates with pilot performance. Douglas C. Johnson, a professor of psychiatry at the University of California, San Diego, is part of a consortium of researchers called the OptiBrain Center, where he is interested in COMT’s role in combat performance and well-being.
While the studies are ongoing, the early results show those with Worrier-genes can still handle incredible stress — as long as they are well trained. Even some Navy SEALs have the Worrier genes, so you can literally be a Worrier-gene Warrior. In Kennedy’s sample, almost a third of the expert pilots were Worriers — a larger proportion than in the general population.” Read the whole article.
