truly successful decision making relies on a balance between deliberate and instinctive thinking. . . . Deliberate thinking is a wonderful tool when we have the luxury of time, the help of a computer, and a clearly defined task, and the fruits of that type of analysis can set the stage for rapid cognition. . . . in good decision making, frugality matters. . . . even the most complicated of relationships and problems . . . have an identifiable underlying pattern. . . . Overloading the decision makers with information . . . makes picking up that signature harder, not easier. To be a successful decision maker, we have to edit. . . . Snap judgments can be made in a snap because they are frugal, and if we want to protect our snap judgments, we have to take steps to protect that frugality.
