Thinking, Fast and Slow
Nobel laureate Kahneman synthesized decades of research into a unified theory of human irrationality: System 1 (fast, intuitive, emotional) and System 2 (slow, deliberate, logical). The most widely cited popular psychology book of the 21st century. Obama, Gates, and countless readers name it as the single book that most changed how they think.
Chapter four, the priming chapter, collapsed in the replication crisis, and Kahneman admitted he had placed too much faith in underpowered studies; read that section as history, not science. The rest runs long and repeats itself: by the two selves, the same anchoring and loss-aversion experiments have lectured you three times over five hundred pages.
The case for it and the rest of the canon open with Pro.
