Predictably Irrational

Dan Ariely

Predictably Irrational examines why people repeatedly misjudge value, choice, effort, risk, experience, and honesty. It asks how comparisons, prices, emotions, expectations, ownership, and social signals redirect behavior, then considers how awareness, precommitment, technology, and choice architecture can bring decisions closer to our goals.
