Predictably Irrational by Dan Ariely explores the irrational decisions people make, and how these decisions are often based on emotion rather than logic. Ariely delves into the psychology of why humans act irrationally in certain situations, and how understanding this behavior can help us make better decisions in our own lives. He introduces concepts like the "Decoy Effect," which demonstrates that when presented with multiple options, people will often opt for the middle one instead of the best choice available. Additionally, he discusses topics such as the power of free offers and how anchoring prices to a higher value can lead to more sales.
