WebbThe availability heuristic is a mental shortcut that our brains use to make quickly evaluate probabilities. When we are faced with a decision, we tend to rely on information that comes to mind easily. This can include information that we can recall more easily, events that affected us strongly, and more recent events.

Webb14 jan. 2024 · The first axiom of probability is that the probability of any event is a nonnegative real number. This means that the smallest that a probability can ever be is zero and that it cannot be infinite. The set of numbers that we may use are real numbers. WebbThe base rate fallacy, also called base rate neglect [2] or base rate bias, is a type of fallacy in which people tend to ignore the base rate (i.e., general prevalence) in favor of the individuating information (i.e., information pertaining only to a specific case).
