Confirmation bias is a human-made cognitive taxonomy — a named pattern in how human agents selectively process information. It carves a class of systematic error: the tendency to seek, interpret, favor, and recall information in ways that confirm preexisting beliefs while giving disproportionate weight to disconfirming evidence. Its parameters are (1) directional information search (actively seeking confirming evidence), (2) interpretive asymmetry (ambiguity resolved toward existing beliefs), (3) memory distortion (selective recall of confirming instances), and (4) persistence mechanism: it is tracked and measured through experimental psychology protocols (e.g., Wason selection task, belief-bias paradigm), named in diagnostic frameworks, and mitigated by institutional practices like blind review, pre-registration, and structured analytic techniques. The entry denotes the MAP of the phenomenon — the conceptual category and its measurement tools — not the natural cognitive tendency itself (Law 2a). It persists through research literatures, diagnostic criteria, and trained awareness practices.\n\n[formal: partisanship in cognition | substrate: mind | horizon: hours | explicit: yes | epoch: 0.47]

Definition
Why it is in scope
A human-made cognitive pattern — the documented tendency for people to selectively gather, interpret, and recall information in ways that confirm their preexisting beliefs. It is a construct of cognitive psychology, named and operationalized in research by Nickerson (1998) and others, persisting through academic literature, teaching, and public discourse.

Confirmation-bias is a specific cognitive bias — the tendency to search for, interpret, and recall information that confirms one's preexisting beliefs. It is a subtype of the general cognitive-bias category.

Confirmation bias needs belief to operate now (Law 8): the tendency to seek, interpret, and recall information in ways that confirm preexisting beliefs requires beliefs to exist first. Remove belief — the capacity to hold preexisting positions — and confirmation bias cannot operate. The bias is defined by its relationship to belief, not merely by information-processing.

confirmation-bias IS a specific kind of heuristics-and-biases phenomenon: the tendency to search for, interpret, and recall information that confirms preexisting beliefs. A competent speaker would classify confirmation-bias as a heuristic-and-bias. Direction specific→general.
