Built on the decision science that runs from Tversky and Kahneman onward, this atlas documents 60 cognitive biases — each with a definition, everyday examples, real-world applications, debiasing tactics and the scholarly sources behind it.
Grouping the Cognitive Bias Codex by why the brain fails, Buster Benson sorts the biases into four mechanisms: too much information, not enough meaning, the need to act fast, and the limits of memory. Every category page can be expanded entry by entry.
Research shows that simply learning about a bias produces only short-lived alertness. Repeated training, structured decision procedures and techniques such as the premortem are what deliver measurable, lasting effects.
