A series of 5 experiments with 660 adult Ss studied how people judge the frequency of death from various causes. The judgments exhibited a highly consistent but systematically biased subjective scale of frequency. Two kinds of bias were identified: (a) a tendency to overestimate small frequencies and underestimate larger ones; and (b) a tendency to exaggerate the frequency of some specific causes and to underestimate the frequency of others, at any given level of objective frequency. These… Expand
When does a response error become a judgmental bias? Commentary on "Judged Frequency of Lethal Events".
The study of Lichtenstein, Slovic, Fischhoff, Layman, and Combs reports several types of errors in subjects' frequency judgments of lethal events. These errors are interpreted as reflecting theExpand
Individuals' Estimates of the Risks of Death: Part II—New Evidence
Using new survey data, we test the hypothesis that individuals' perceptions of health and safety risks are unbiased. While we find that respondents' estimates of those risks are sensitive to theExpand

TLDR
Although the experts outperformed lay persons on a number of measures, the differences are small, and both groups showed similar global biases in terms of: (1) overestimating the likelihood of dying from a condition (marginal probability) and (2) underestimating the ratios of marginal and conditional likelihoods between pairs of potentially lethal events.

Affect, Generalization, and the Perception of Risk.
Experimental manipulations of affect induced by a brief newspaper report of a tragic event produced a pervasive increase in subjects' estimates of the frequency of many risks and other undesirableExpand
Do We Relatively or Absolutely Overestimate Rare Events
How good are we at estimating the frequency of rare events? Previous evidence has been mixed: While some studies report well-calibrated frequency judgments, others found rare events to beExpand
Individuals' Estimates of the Risks of Death: Part I—A Reassessment of the Previous Evidence
It is widely argued that individuals have biased perceptions of health and safety risks. A reconsideration of the best-known evidence suggests that this view is the erroneous result of a failure toExpand
The Representation of Mortality Statistics and the Perceived Importance of Causes of Death
TLDR
Analysis showed that subjects discriminated between the different causes both before and after presentation of the information but their ratings were imperfectly calibrated with actual frequencies, which depended significantly on the mode of presentation. Expand

Abstract : Two experiments investigated the kinds of frequency information that people can remember and individual differences in accuracy of reporting frequency. The task involved presentingExpand

People seriously misjudge accident risks because they routinely neglect relevant information about exposure. Such risk judgments affect both personal and public policy decisions (e.g., choice of aExpand

The base-rate fallacy is people’s tendency to ignore base rates in favor of, e.g., individuating information (when such is available), rather than integrate the two. This tendency has importantExpand
