Abstract

It is unknown whether a ‘jumping to conclusions’ (JTC) data-gathering bias is apparent in specific delusion sub-types. A group with persecutory delusions is compared with a sample of non-clinical controls on a probabilistic reasoning task. Results suggest JTC is apparent in individuals with the persecutory sub-type of delusions.
