Amazing Decisions follows the narrator, Adam, as he faces the daily barrage of choices and deliberations. He juggles two overlapping―and often contradictory―sets of norms: social norms and market norms. These norms inform our thinking in ways we often don’t notice, just as Adam is shadowed by the “market fairy” and the “social fairy,” each compelling him to act in certain ways. Good decision-making, Ariely argues, requires us to identify and evaluate the forces at play under different circumstances, leading to an optimal outcome. Amazing Decisions is a fascinating and entertaining guide to developing skills that will prove invaluable in personal and professional life.
