Gerd Gigerenzer writes psychology and decision-science books about risk, uncertainty and the usefulness of simple rules. Reckoning with Risk explains why medical statistics and probabilities are often misunderstood and shows how formats such as natural frequencies can make risk easier to interpret. Gut Feelings argues that fast heuristics can perform well when they are matched to the structure of a problem rather than treated as inferior versions of complex calculation. Risk Savvy extends the argument into medicine, finance and public policy, asking how people can make sensible decisions when exact probabilities are unavailable. Gigerenzer's prose is clear and sceptical of unnecessary complexity, with experiments and real cases used to challenge the idea that more information always improves judgement. His work fits behavioural science, risk literacy and decision psychology. Read more Less
