“…Though the findings reviewed above suggest a general tendency for needs for security and certainty-which reflect a kind of psychological 'rigidity'-to go with the politics of the right, Van Hiel, Onraet, and DePauw (2010) and Van Hiel, Onraet, Crowson, and Roets (2016) find that Psychological differences and political differences -7 'objective' behavioral measures of intolerance of ambiguity and rigidity that assess participants' ability to perform cognitive operations requiring flexibility and attention to multiple, inter-related aspects of a problem are more weakly related to conservatism than 'subjective' self-report measures that explicitly ask participants to indicate how well various statements describe them (e.g., "I enjoy having a clear and structured mode of life"; Webster & Kruglanski, 1994). Reinforcing this, recent studies have failed to replicate earlier results (e.g., Oxley et al, 2008) indicating a correlation between political preferences and strong physiological responses to objective tasks in which participants are exposed to threatening stimuli (Bakker, Schumacher, Gothreau, & Arceneaux, 2020;Osmundsen et al, 2020;Smith & Warren, 2020).…”
