We did a systematic review and meta-analysis to investigate the magnitude and specificity of the "jumping to conclusions" (JTC) bias in @entity716 and @entity8143 . We examined the extent to which @entity1 with @entity716 , and @entity1 with @entity8143 specifically, required less information before making decisions. We examined (1) the average amount of information required to make a decision and (2) numbers who demonstrated an extreme JTC bias, as assessed by the "beads task." We compared @entity1 with @entity716 to @entity1 with and without nonpsychotic mental health problems, and @entity1 with @entity716 with and without @entity8143 . We examined whether reduced data-gathering was associated with increased delusion severity. We identified 55 relevant studies, and acquired previously unpublished data from 16 authors. @entity1 with @entity716 required significantly less information to make decisions than healthy individuals (k= 33,N= 1935,g= -0.53, 95% CI -0.69, -0.36) and those with nonpsychotic mental health problems (k= 13,N= 667,g= -0.58, 95% CI -0.80, -0.35). The odds of extreme responding in @entity716 were between 4 and 6 times higher than the odds of extreme responding by healthy @entity1 and @entity1 with nonpsychotic mental health problems. The JTC bias was linked to a greater probability of delusion occurrence in @entity716 (k= 14,N= 770, OR 1.52, 95% CI 1.12, 2.05). There was a trend-level inverse association between data-gathering and delusion severity (k= 18;N= 794;r= -.09, 95% CI -0.21, 0.03). Hence, nonaffective @entity716 is characterized by a hasty decision-making style, which is linked to an increased probability of @entity8143 .
