我们为什么会做错误的决定？

Human brains are wired to make systematic errors when judging both probabilities and value, leading to irrational decisions in everyday life. People overestimate risks that grab attention, like tornadoes and terrorism, and undervalue common dangers such as drowning or asthma. Even when a centuries-old formula promises rational decisions, our instincts still steer us astray—whether we’re buying lottery tickets, choosing jobs, or planning for the future. These mental shortcuts persist because our minds evolved for a world of simple choices and immediate needs, not today’s complex society.
