Anti-establishment sentiments: realistic and symbolic threat appraisals predict populist attitudes and conspiracy mentality.

Previous research has found that populist attitudes and conspiracy mentality - here summarised as anti-establishment attitudes - increase when people feel threatened. Two types of intergroup threat have been distinguished, namely realistic threats (pertaining to socio-economic resources, climate, or health), and symbolic threats (pertaining to cultural values). However, there is no agreement on which types of threat and corresponding appraisals would be most important in predicting anti-establishment attitudes. We hypothesise that it is the threat itself, irrespective of its cause, that predicts anti-establishment attitudes. In the current paper, we conducted new (multilevel) regression analyses on previously collected data from four high-powered studies with multiple time points (Study 1) or collected in multiple nations (Studies 2-4). All studies included a populist attitudes scale, a conspiracy mentality scale, and different types of threat and emotion measures, reflecting both realistic and symbolic threats. Across studies, both realistic and symbolic threats positively predicted anti-establishment attitudes. The results support an emotional appraisal approach to anti-establishment attitudes, which highlights the importance of anxiety and feeling threatened regardless of what type of event elicits the threat.
