What People Say

Predictably Irrational is a cornerstone of behavioural economics that authors across finance, marketing, design, and decision science treat as essential reading. Daniel Kahneman cites it in Thinking, Fast and Slow, Rory Sutherland references Ariely's experiments on anchoring and the power of "free" in Alchemy, and William Poundstone uses his decoy-pricing research throughout Priceless.

Oren Klaff draws on Ariely's work to explain why facts alone cannot persuade investors, while Cathy O'Neil warns in Weapons of Math Destruction that replacing human judgement with algorithms merely encodes Ariely's irrational patterns in code. Readers appreciate how the book makes systematic biases visible through entertaining experiments, though Gerd Gigerenzer pushes back in Risk Savvy, arguing that the blanket claim of human irrationality overstates the case.
