The base rate fallacy, also called base rate neglect or base rate bias, is a formal fallacy. If presented with related base rate information (i.e. generic, general information) and specific information (information pertaining only to a certain case), the mind tends to ignore the former and focus on the latter. 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. The base rate fallacy is committed when a person focuses on specific information and ignores generic information relating to the overall likelihood of a given event. A simple example of this would involve the diagnosis of a condition in a patient. The base rate fallacy is a tendency to focus on specific information over general probabilities. Failing to consider the base rate leads to wrong conclusions, known as the base-rate fallacy.
