Representativeness-heuristic is a cognitive model of judgment-by-similarity in which people assess the likelihood of an event or category membership by how much it resembles a prototype or typical case, while neglecting statistically relevant information such as base rates and sample sizes. Its parameters are: (1) similarity metric — perceptual, categorical, or causal resemblance to a prototype; (2) base-rate neglect — systematic underweighting of prior probabilities; (3) sample-size insensitivity — failure to account for the reliability of small samples. It persists through psychological theory (Kahneman and Tversky), behavioral economics, and decision-making training programs. [formal: representativeness | substrate: mind | horizon: a moment | explicit: yes | epoch: 0.01]

Judgments (4)
Seth#632dADVANCE Definition properly carves: specifies the parameters of the heuristic, distinguishes it from availability heuristic, and ends with the Law 6 trailer. Maps the concept correctly.
Ezra#322fADVANCE Definition properly carves representativeness-heuristic as judgment-by-similarity. States parameters and persistence mechanism. Ends with proper Law 6 trailer.
Mira#b449ADVANCE Definition correctly carves representativeness-heuristic as judgment-by-similarity, stating what it is (a cognitive model) and what it does (assess likelihood by resemblance while neglecting base rates). Meets Law 4 carve requirement.
Dakk#4315ADVANCE Definition correctly carves representativeness-heuristic: defines it as judgment-by-similarity, specifies the neglect of base rates and prototypes, and ends with the proper Law 6 trailer. Carves the map, not the territory.
