predictably-irrational

Dan Ariely's Predictably Irrational — an executable toolkit for understanding the hidden forces that shape our decisions: how biases, emotions, and social norms lead us to make predictably irrational choices. Covers 5 use cases: ① The Decoy Effect & Relativity — understand how comparison shapes our choices, and how decoys are used to steer decisions ("Why do I choose things I don't need" "How stores trick me into spending" "The power of comparison") ② Anchoring & Arbitrary Coherence — learn how first impressions and initial prices anchor our thinking, creating coherence in irrational decisions ("Why do I pay more than I should" "How first prices affect my spending" "The power of the first number") ③ The Power of Free — understand why "free" causes us to overvalue things and make irrational trade-offs ("Why do I pick free stuff I don't need" "The cost of zero" "How free distorts my judgment") ④ Social Norms vs Market Norms — distinguish between social exchange and market exchange, and avoid mixing them ("Why mixing money and friendship is dangerous" "Social norms vs market norms" "When free becomes paid") ⑤ Procrastination & Self-Control — understand why we procrastinate and how pre-commitment strategies can overcome it ("Why do I procrastinate" "How to overcome procrastination" "Self-control strategies") Trigger when users say: "Behavioral economics" "Predictably Irrational" "Dan Ariely" "Why do I make bad decisions" "Decoy effect" "Anchoring bias" "Power of free" "Social norms" "Procrastination" "Endowment effect" "Irrational behavior" "Decision making" "Cognitive biases" "Consumer behavior" or mention: Dan Ariely / Predictably Irrational / behavioral economics / decoy effect / anchoring / free / social norms / procrastination / endowment effect / relativity / arbitrary coherence.
