Framing And Anchoring Effects

A decision bias in which the way a choice or a number is presented, rather than its underlying substance, measurably shifts the judgment a person makes, whether by casting the same outcome in gain or loss terms or by fixing attention on an initial reference value that then pulls subsequent estimates toward it. This group gathers the framing and anchoring phenomena recorded for this atlas, a foundational pair of concepts in behavioral economics and judgment-and-decision-making research documenting how presentation and initial reference points systematically bias human judgment.
