Base rate fallacy (or base rate neglect) is the tendency to mistakenly estimate the likelihood of an event without taking account of all the relevant data (e.g. generic   Learn about common heuristics, biases, and other factors that affect our decisions. The Base Rate Fallacy / Bias When you ignore (or don’t understand) general statistical data and make a judgment based on specific data, you’re falling prey to the base rate fallacy. This happens all the time ; People not well-versed in the technical rules of prior probability usually don’t take the prior statistical data into account, as it doesn’t seem relevant. Someone making the 'base rate fallacy' would infer that there is a 99% chance that the detected person is a terrorist. Although the inference seems to make sense, it is actually bad reasoning, and a calculation below will show that the chances he/she is a terrorist are actually near 1%, not near 99%. 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.

In each case, we are tricked by a base rate fallacy, one much-discussed in the psychological literature. In this paper we consider this accusation and use it as an 

Fight fire with fire and beat bias with bias. To conclude the trilogy of posts on the representativeness heuristic, I here propose that base rate neglect can be reduced if base rates are first Base Rate Fallacy. A base rate fallacy is committed when a person judges that an outcome will occur without considering prior knowledge of the probability that it will occur. They focus on other information that isn't relevant instead. Imagine that I show you a bag of 250 M&Ms with equal numbers of 5 different colors. 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.

On game day, 38 out of 2.5 million people in Toronto are National Hockey League (NHL) players (i.e., the Leafs and their opponent). Thus, the base-rate probability that a randomly encountered person in Toronto on game day is a NHL player is 38/2,500,000 or .00152%. 3 mins on base rate fallacy, take a look!
