““Insight 1: Human decision making serves evolutionary goals. The traditional way of thinking about human behavior is based almost completely on a consideration of people’s surface goals—getting a decent bargain on a pair of dress shoes, for example, or picking a fine restaurant for a date next Saturday. But humans, like all animals, evolved to make choices in ways that promote deeper evolutionary purposes. Once we start looking at modern choices through this ancestral lens, many decisions that appear foolish and irrational at the surface level turn out to be smart and adaptive at a deeper evolutionary level. Insight 2: Human decision making is designed to achieve several very different evolutionary goals. Economists and psychologists have often assumed that humans seek a single broad goal: to feel good or to maximize benefits. In actuality, all humans pursue several very different evolutionary goals, such as acquiring a mate, protecting themselves from danger, and attaining status. This is an important distinction. Depending on which evolutionary goal they currently have in mind, consciously or subconsciously, people will have very different biases and make very different choices.””
