The anchoring heuristic is a cognitive bias in which individuals rely disproportionately on the first piece of information encountered (the anchor) when making subsequent judgments and decisions. Once an anchor is set, all further judgments are made by adjusting away from that anchor, and adjustments are typically insufficient — resulting in a final judgment biased toward the initial anchor. The parameters that define the anchoring heuristic are: (1) an initial value or datum is presented, (2) subsequent estimates are generated by adjustment from that value, and (3) adjustments are insufficiently large. The persistence mechanism is cognitive: the heuristic operates automatically in human judgment and is documented through experimental demonstration in behavioral economics and cognitive psychology, transmitted through teaching, research literature, and applied practice.

Definition
Why it is in scope
A cognitive shortcut where individuals rely too heavily on the first piece of information encountered (the 'anchor') when making decisions. Subsequent judgments are made by adjusting away from that anchor, and adjustments are typically insufficient. The construct is human-made: it was identified and formalized by Tversky and Kahneman in 1974 as part of research on judgment under uncertainty, and persists through scientific literature, behavioral economics, and applied fields like negotiation and marketing.

Anchoring heuristic is a specific cognitive bias where initial information (anchor) disproportionately influences subsequent judgments. A competent speaker would classify it as 'a cognitive bias' — it is a systematic error in judgment, fitting the established cognitive-bias entry.

The anchoring heuristic (starting from an anchor and adjusting insufficiently) is the cognitive mechanism that produces the anchoring effect (the measured bias phenomenon). The heuristic existed as a mental strategy before the effect was formally identified in the Tversky-Kahneman literature — which-came-first test: the heuristic came first and fed into the effect.
