This reaction is very common and called Base Rate Fallacy or Base Rate Neglect. The CIA has a nifty article on this, and it explains how people often gravitate towards the easiest information available when making decisions. Base rates may be neglected more often when the information presented is not causal. Base rates are used less if there is relevant individuating information. Groups have been found to neglect base rate more than do individuals. Use of base rates differs based on context. Second, people are more likely to use base rates when they have no individuating or case-specific information to use in its place. People are more likely to utilize base rates, for instance, when predicting the behavior of a randomly selected person than when predicting their own behavior, Base rates, stereotypes, and judgmental accuracy - Volume 19 Issue 1 - David C.

Base rate fallacy, or base rate neglect, is a cognitive error whereby too little weight is placed on the base (original) rate of possibility.

Blue cabs make up 85% of the cab population. There was a hit-and-run accident involving a cab, and the witness believed that the cab was green. Witnesses are 80% accurate at discerning between blue and green cabs. What is the chance that the cab is green? Many people would say 80%, or something close to it, because they ignore the base rate.

Base rate fallacy (also known as base rate neglect): Incorrectly ignoring statistical information in favor of irrelevant information to make a judgment. Prosecutor's fallacy: Jurisprudence in the USA can be described as poorly executed statistical inference done by three unqualified statisticians before a statistically ignorant jury.

I am on p.56, Vol 2 of curriculum 2014. From my understanding, representative bias means that people tend to overweigh new information because they think that the new information is representative of the whole population. Sample-size neglect seems consistent with this definition. However, I don't understand why base-rate neglect (the base rate or probability of the Base rate fallacy (also known as base rate neglect): Incorrectly ignoring statistical information in favor of irrelevant information to make a judgment. Prosecutor's fallacy: Jurisprudence in the USA can be described as poorly executed statistical inference done by three unqualified statisticians before a statistically ignorant jury. Base rate neglect The failure to incorporate the true prevalence of a disease into diagnostic reasoning. For example, we often overestimate the pre-test probability of pulmonary embolism, working it up in essentially no risk patients, skewing our Bayesian reasoning and resulting in increased costs, false positives, and direct patient harms. Imagine that there is a rare genetic disease that affects 1 in every 100 people at random. There is a test for this disease that has a 99% accuracy rate: of every 100 people tested it will give the correct answer to 99 of those people.

This article illuminates the base rate fallacy, also known as Insensitivity To Base Rates and goes on to show how it affects our decisions and outcomes. Chapter 2. Base-rate neglect. Gordon Pennycook and Valerie A. Thompson. The “base-rate” refers to the a-priori probability of an event or outcome. For example Base Rate Fallacy is our tendency to give more weight to the event-specific information than we should, and sometimes even ignore base rates entirely.
