We discuss three examples of such research: base-rate neglect, in which people ignore critical background information in favor of less reliable case-specific information; the conjunction fallacy, in which people report that the conjunction of two events is more likely to have occurred than one of the events alone; and the sunk-cost effect, 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.

There is a famous cab driver problem illustrated by the behavioural psychologist, and Nobel laureate, Daniel Kahneman, which demonstrates this phenomenon clearly. 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.
