Drawing upon evidence from broader social psychology, and an illustrative study of frequency-estimation during a simple, sport-specific observe-and-recall task, this paper makes the case for the more thorough investigation of the availability heuristic (Tversky & Kahneman, 1973) on practical state-of-play reasoning in largely observational sporting activities. It is argued that this evidence particularly substantiates a need for a more robust body of research in two primary domains: (a) the gatekeeping tasks pertinent (and usually preliminary) to an individual's sporting performance such as talent scouting, team selection, and substitution decisions, and (b) the business of officiating in high-tempo environments.
