The belief bias in reasoning occurs when individuals are more willing to accept conclusions that are consistent with their beliefs than conclusions that are inconsistent. The present study...

Cognitive reflection, or the ability to inhibit intuitive and incorrect responses in favour of correct responses, predicts performance on a variety of cognitive tasks. The present study examined interventions to improve cognitive reflection. In two experiments, college students (N = 491) were assigned to one of three conditions, completed two versions of a cognitive reflection test (CRT), and then completed transfer tasks. Between the two CRTs, some participants were provided with elaborative feedback, others were instructed to consider additional responses for (...) their initial responses and the final group was a control. In both experiments, CRT performance increased between the first and second CRT in the feedback and instruction groups, but not in the control group. There was little evidence, however, for transfer to other tasks. These results suggest that cognitive reflection performance can be improved with brief interventions but that this improvement may not transfer to related tasks. (shrink)

This study investigated ideological belief bias, and whether this effect is moderated by analytical thinking. A Swedish nationally representative sample (N = 1005) evaluated non-political and political syllogisms and were asked whether the conclusions followed logically from the premises. The correct response in the political syllogisms was aligned with either leftist or rightist political ideology. Political orientation predicted response accuracy for political but not non-political syllogisms. Overall, the participants correctly evaluated more syllogisms when the correct response was congruent with their (...) ideology, particularly on hot-button issues (asylum to refugees, climate change, gender-neutral education, and school marketization). Analytical thinking predicted higher accuracy for syllogisms of any kind among leftists, but it predicted accuracy only for leftist and non-political syllogisms among rightists. This research contributes by refining a promising paradigm for studying politically motivated reasoning, demonstrating ideological belief bias outside of the United States across diverse political issues, and providing the first evidence that analytical thinking may reduce such bias.
