Whether the decision is to have unprotected sex, consent to surgery, spend rather than save for retirement, or have an extra piece of pie, risky decisions permeate our lives, sometimes with disastrous consequences. How and why risk taking occurs has important implications, yet many questions remain about how various factors influence decision-making.

This book advances basic understanding and scientific theory about the brain mechanisms underlying risky decision making, paving the way for translation of science into practice and policy. This compelling research topic crosses a number of disciplines, including developmental and cognitive psychology, brain sciences, law, behavioural economics, and addiction.
