Anchoring and Adjustment

Anchoring and adjustment is a phenomenon wherein an individual bases their initial ideas and responses on one point of information and makes changes driven by that starting point. The anchoring and adjustment heuristic describes cases in which a person uses a specific target number or value as a starting point, known as an anchor, and subsequently adjusts that information until an acceptable value is reached over time. Often, those adjustments are inadequate and remain too close to the original anchor, which is a problem when the anchor is very different from the true answer.
