When we are not experts and we don’t have time to compare and choose rationally among options, the best choice is often to do nothing. Because novices are prone to make the wrong move, the right move is often no move at all. Even the world’s leading experts are novices some of the time, and when that happens they often should do nothing.
If we are novices, by the time we have only seconds left to make a decision, it is often too late. The best decisions made in time-pressured situations are those we have prepared for in advance. The real challenge is to anticipate those situations in which we, as experts, might suddenly become novices, and then train for those scenarios.
