| Abstract: | Recent categorization research set in abstract medical diagnosis contexts has demonstrated an "inverse base rate effect", whereby subjects make diagnoses which are consistent with base rates when presented with some sets of symptoms. This paper reports three experiments which demonstrate that whether or not the inverse base rate effect is observed depends on the context in which categorization takes place. Inverse base rate effects are replicated in the abstract medical diagnosis context used in prior research , but not in a relatively realistic financial auditing setting, a less realistic financial auditing setting, or a very abstract generic setting. |
