The Psychophysiology of Political Ideology: Replications, Reanalysis and Recommendations

Abstract: This article presents a large-scale, empirical evaluation of the psychophysiological correlates of political ideology and, in particular, the claim that conservatives react with higher levels of electrodermal activity to threatening stimuli than liberals. We (1) conduct two large replications of this claim, using locally representative samples of Danes and Americans; (2) re-analyze all published studies and evaluate their reliability and validity; and (3) test several features to enhance the validity of psycho… Show more

“… 14 The alpha reliability scores are 0.08 for reactions to disgusting photos and 0.22 for reactions to threatening photos. These results are analogous to those reported in Osmundsen et al (Forthcoming; 0.12); see also the weak correlations in Figure 1 of Bakker et al (2020). However, see our comment in footnote 11.…”

“…Third, we readily acknowledge the possibility that the physiological variables examined here may or may not be indicative of deep-seated predispositions in information processing. There is at present some debate about whether physiological responses to photos should be regarded as predispositional (Bakker et al 2020; Osmundsen et al Forthcoming). Recent work suggests that responses to video or photo stimuli capture some combination of deep-seated predispositional and more time- and context-varying responses (Soroka et al 2019), a suggestion echoed in work looking at headline selection tasks in panel survey experiments (Bachleda et al 2020).…”

“…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).…”
