Domain-specific¶
- Availability Heuristic
- Lichtenstein and colleagues (1978) showed the signature directly: dramatic, publicized causes of death (accidents, homicide, tornadoes) were overestimated while quiet, common ones (stroke, diabetes, asthma) were underestimated, and the errors left after allowing for true frequency lined up, moderately, with how often each cause was reported in the newspapers, coverage that bore little relation to how often each cause killed
This sourceThe over- and under-estimation of 41 causes of death — dramatic, publicised causes over, quiet common killers under — with the errors left after allowing for true frequency correlating moderately with newspaper coverage. The study design in which people estimated annual U.S. deaths from 41 causes.

- Spotlight Fallacy
- The defining demonstration is the study of judged frequencies of lethal events by Lichtenstein, Slovic, Fischhoff, Layman, and Combs (1978)
This sourceThe original experiments on lay judgments of how often various causes of death occur, finding systematic bias traced to exposure and memorability. The direction of the errors (accidents, homicide, tornadoes and fire overestimated; stroke, diabetes and asthma underestimated), including stroke outkilling all accidents and asthma outkilling tornadoes.

Verification¶
Does it exist? Not checked yet. This work's DOI is recorded above but has not been resolved against an external catalogue, so nothing here confirms the work exists.
Does it back the claim? Read against the text for 2 of 2 citations: 2 supported. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
