Predictably Irrational

In this revised and expanded edition of the groundbreaking New York Times bestseller, Dan Ariely uses a series of illuminating experiments to show how expectations, emotions, social norms, and other invisible forces skew our reasoning abilities.

Ariely explains how we consistently overpay, underestimate, and procrastinate, and how these behaviors are neither random nor senseless but systematic and predictable.

The book covers various aspects of decision-making, from the power of placebos to the effects of social and financial norms, and offers insights into how to make better decisions by understanding these irrational patterns.
