Confirmation Bias

Mental models

Once you own a position, evidence stops being neutral: what supports the thesis is sought and remembered, what contradicts it is discounted or never looked up. The counter is structural rather than moral - write the bear case before buying and name what would make the position a zero. When news breaks, reread the original thesis rather than the price chart.

How the wish for agreement in close groups led to fiascos like the Bay of Pigs.

“One of my favourite books, Groupthink by Irving Janis, breaks down how small, cohesive groups of very smart people can make very bad decisions.” — Adam Weiss

Thinking, Fast and SlowThinking, Fast and Slow
T1 Thinking, Fast and Slow
Daniel Kahneman · 2011

Kahneman's synthesis of behavioral economics is the cognitive science underpinning every negotiation tactic. Anchoring, loss aversion, framing effects, and the planning fallacy — understanding why these biases operate, not just that they exist, makes you harder to exploit and more honest about your own irrationality.

Carol Tavris, Elliot Aronson · 2007
Open LibraryGoodreads

Tavris and Aronson focus on what happens after a bias fires: the self-justification, narrative revision, and escalating commitment that follow. Cognitive dissonance, they argue, is not a personality flaw but a universal mechanism, and understanding it explains police misconduct, political tribalism, and therapy failures in a single framework.
