## Base rate fallacy statistics

The Base Rate Fallacy is an error in reasoning which occurs when someone reaches a conclusion that fails to account for an earlier premise – usually a base rate, a probability or some other statistic. The base rate fallacy occurs when the base rate for one option is substantially higher than for another. Example Consider testing for a rare medical condition, such as one that affects only 4% (1 in 25) of a population.

Every accurate (model|test) can be useless as detection tools if the studied case is sufficiently rare among the general population. The data model will produce  In each case, we are tricked by a base rate fallacy, any elementary statistics text will remind us, however, we must consider the sample from which this patient   26 Feb 2019 In other words - where do you find your base rates? are all aware from Thinking, Fast and Slow, one of the largest decision-making errors we make is the Base Rate Fallacy. I often use the Office for National Statistics (UK).

BASE-RATE FALLACY: "If you overlook the base-rate information that 90% and then 10% of a population consist of lawyers and engineers, respectively, you would form the base-rate fallacy that someone who enjoys physics in school would probably be categorized as an engineer rather than a lawyer. Base Rate Fallacy Definition Imagine that you meet Tom one evening at a party. He is somewhat shy and reserved, is very analytical, and enjoys reading science fiction novels. What is the likelihood that Tom works as a computer scientist? The answer depends on both the knowledge you have about Tom and the number of … The base rate fallacy shows us that false positives are much more likely than you’d expect from a \(p < 0.05\) criterion for significance. Most modern research doesn’t make one significance test, however; modern studies compare the effects of a variety of factors, seeking to find those with the most significant effects. Base-rate fallacy: People ignore the relative sizes of population subgroups when judging the likelihood of contingent events involving the subgroups. You have to consider the base population for comparison. Maybe a company is comprised of 80 percent men and 20 percent women.
