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.
许多研究结果表明，患有妄想症的个体存在推理偏差。在概率推理任务中，他们在决策时表现得很仓促。患有妄想症的个体比没有妄想症的个体所需信息更少，即使额外的数据很容易获取。此外，他们也更坚信自己做出了正确的决定。这一发现已被多项研究所重复。然而，先前的研究尚未证实“急于下结论”偏差的根源，其在妄想形成过程中的作用也尚未得到证实。该文章对患有妄想症的人群中“急于下结论”偏差的研究结果进行了综述。它讨论了解释仓促决策与妄想形成之间关系的主要假设。文章还探讨了患有妄想症个体的“急于下结论”偏差的特点，并总结了其与智力水平或妄想强度等因素的关系。
