Anchoring and Adjustment: Influence of Initial Numbers
Discover how the anchoring bias affects judgments based on initial numbers, even in rigged scenarios.
What is this page about?
An in-depth explainer of the anchoring-and-adjustment heuristic, the process by which people estimate by starting from an initial value and adjusting insufficiently, opening with Tversky and Kahneman's 1974 rigged wheel-of-fortune experiment. It covers the competing cognitive accounts (insufficient adjustment, confirmatory hypothesis testing, and Epley and Gilovich's external-versus-self-generated anchor distinction), the role of cognitive load, four case studies (real-estate appraisal, clinical diagnosis, legal sentencing, investment valuation), effect sizes, the limits of debiasing, and boundary conditions.
