KembaraXtra-Psychology – Base Rate
A base rate is the underlying probability or frequency with which a particular event occurs in a given population before any specific case-related information is considered. For example, the base rate of a disease refers to its prevalence within a population. Accurate probabilistic reasoning requires integrating base-rate information with case-specific evidence, yet individuals often neglect such statistical background information. Base rates provide an essential benchmark against which new data should be evaluated.
