As Malcolm Gladwell pointed out in his 2000 article on the psychology of choking, the phenomenon can seem like an amorphous category of failure. Nevertheless, choking is actually triggered by a specific mental mistake: thinking too much. The sequence of events typically goes like this: When people get anxious about performing, they naturally become particularly self-conscious; they begin scrutinizing actions that are best performed on autopilot. The expert golfer, for instance, begins contemplating the details of his swing, making sure that the elbows are tucked and his weight is properly shifted. This kind of deliberation can be lethal for a performer.
