Rationality For Mortals by Gerd Gigerenzer

How People Cope with Uncertainty

Explores how people make decisions under uncertainty using simple heuristics that are well adapted to real-world environments, often outperforming complex models. It introduces the idea of ecological rationality, shows how presenting risks as natural frequencies improves judgment, and offers evidence from medicine, finance, and law. The result is a case for bounded rationality and practical tools for cultivating risk literacy and smarter, faster decision-making.
