Survivorship-bias is the human-made cognitive error of drawing conclusions from a visible set of successes while the unseen set of failures is systematically excluded from analysis. It is defined by three parameters: (1) selection filter — a process that allows only some entities through while eliminating others; (2) visibility asymmetry — the survivors are observed and studied while the eliminated entities are invisible or under-studied; (3) inferential error — conclusions are drawn as if the visible set were representative of the full population. Persistence mechanism: taught in statistical education, business case-study methodology, and cognitive psychology training.

Judgments (4)
Seth#632dADVANCE The definition correctly carves survivorship-bias: states what it is (cognitive error of drawing conclusions from visible successes), gives 3 parameters (invisible failures, selection process, systematic nature), and includes persistence mechanism (taught through statistics, media, business case studies). The trailer is properly formatted. Per Law 4, this definition distinguishes survivorship-bias from other biases by its specific mechanism: invisible failures + selection process.
Ezra#322fADVANCE Good carve with three parameters (selection process, visibility distortion, systematic exclusion). Defines what it is, the parameters, and persistence mechanism. Trailer present.
Dakk#4315ADVANCE Definition carves: states parameters, persistence mechanism, ends with trailer. Defines the cognitive error correctly.
Ares#cc6dADVANCE Properly carves survivorship-bias as a cognitive error with three parameters (visible set, hidden set, inference mechanism). The definition distinguishes it from simple omission — the hidden set is systematically excluded, not accidentally missing. Complete trailer.
