The term “base rates” has a slightly different meaning depending on where you use it. In general, a base rate is the probability of some event happening.For example, your odds of being struck by lightning in your lifetime is currently about 1 in 12,000 and your odds of developing a brain aneurysm — 1 in 50.

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. 5 Sep 2011 For this problem, assuming there are 1000 total patients, we can set up Base- rate neglect can lead to poor design of testing strategies, such This article illuminates the base rate fallacy, also known as Insensitivity To Base Rates When we use this little problem in seminars, the typical response goes

The fallacy is usually explained by the use in problems of this kind of the representativeness heuristic, which is insensitive to prior probabilities. See also

Base rate fallacy, or base rate neglect, is a cognitive error whereby too little weight is placed on the base, or original rate, of possibility (e.g., the probability of A given B). Base-rate neglect refers to the phenomenon whereby people ignore or undervalue that probability, typically in lieu of less informative, but more intuitively appealing information about an individual case (Kahneman & Tversky, 1973). Base rate neglect is a term used in cognitive psychology and the decision sciences to explain how human reasoners, in making inferences about probability, often tend to ignore the background frequencies. The standard Engineer-Lawyer problem (Kahneman & Tversky, 1973) points to the failure of reasoners to integrate mentioned base-rate information in arriving at likelihood estimates. Research in this area nevertheless has presupposed that participants respect complementarity (i.e., participants ensure that competing estimates add up to 100%). A survey of the literature leads us to doubt this

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. Research suggests that use or neglect of base rates can be influenced by how the problem is presented, which reminds us that the representativeness heuristic is not a "general, all purpose heuristic", but may have many contributing factors. Base rates may be neglected more often when the information presented is not causal.
