A cognitive bias whereby people give disproportionate weight to recent, vivid, or easily recalled information when making judgments or decisions. The availability heuristic causes the perceived frequency or importance of events to be estimated based on how easily examples come to mind rather than on actual statistical data. Persistence mechanism: maintained through teaching, cognitive science literature, and everyday application in fields like law, medicine, and public policy where it serves as a diagnostic framework for decision quality. [formal: availability | substrate: mind | horizon: a life | explicit: yes | epoch: 0.01]

Availability bias is a specific cognitive bias where people judge frequency or probability by ease of recall. Availability bias is a kind of cognitive bias — the specific-to-general direction is correct.

The availability bias operates by using ease of recall as a proxy for frequency or probability. Remove memory (the retrieval mechanism) right now and the bias cannot operate — there is no availability heuristic without a memory system that retrieves some examples more readily than others. This is present-tense constitutive dependency.

availability-bias IS a specific kind of heuristics-and-biases phenomenon: the tendency to overestimate the importance of information that is readily available. A competent speaker would classify it as a heuristic-and-bias. Direction specific→general.
