Sources of Power: How People Make Decisions

Gary Klein studies decision-making in the field, tagging along with firefighters, standing by in intensive-care units, and watching chess masters play lightning-fast "blitz" games to learn how people make choices with time constraints, limited information, and changing goals. From this research, he and his associates have developed a theory of "naturalistic decision-making."

Sources of Power essentially lends the validity of scientific research to techniques that many of us use every day. There's intuition, which is based not on instantaneous insight but on the rapid (perhaps even subconscious) interpretation of perceptual cues. There's mental simulation, a finely honed method of visualization. There's storytelling and metaphor, which enable decision-makers to devise meaningful frameworks and compare their present situations to previous events. Nobody is born with an inherent mastery of these and other techniques, Klein tells us, but we are all born with the capability to develop, through experience, the skill sets experts call upon to make good decisions.
