The results of many researches indicate that individuals with delusions reveal the reasoning bias. In probabilistic reasoning tasks they reveal hastiness in decision - making. The individuals with delusions request less information than non - deluded individuals, even if additional data is easily available. What is more, they also prove to be convinced to a greater extend of having made the right decision. This finding has been replicated by a number of studies. However, the previous researches have not confirmed the origins of 'jumping to conclusion' bias, and its role in the process of forming delusions has not been yet confirmed. The article in question contains the review of the results of the jumping to conclusion bias in people with delusions. It discusses the main hypotheses explaining the relations between the hasty decision making and the delusions formation. The article also deals with the specifics of 'jumping to conclusion' bias in case of individuals with delusions, as well as summarizes its relation to factors such as the level of intelligence or the intensity of delusion.
