Abstract: For many people, the coronavirus pandemic meant an enormous and existential loss of control. At the same time, an increase in right-wing extremist attitudes like xenophobia could be observed in Germany. In this study, we hypothesize that the loss of control caused by the pandemic has contributed to the rise in xenophobic and anti-Semitic attitudes in Germany. We propose that this occurs through an attempt to restore control via elements of a revised authoritarian syndrome understood as both the classic authoritarian dynamic of aggression, submission and conventionalism on the one hand, and a general belief in conspiracy theories on the other. In a representative, probability-based study, N = 2522 participants were surveyed on locus of control, right-wing authoritarianism, conspiracy mentality, xenophobia, and anti-Semitism. It was found that right-wing authoritarianism and conspiracy mentality mediated the relationship between external locus of control and xenophobia (partial mediation) and anti-Semitism (full mediation). Surprisingly, internal control beliefs had a direct effect on right-wing authoritarianism—an effect that also leads to increased resentment. We conclude that social crises make people particularly vulnerable to regaining control via conspiracy theories and authoritarianism, which harbors dangers such as right-wing extremism as a consequence. Limitations are discussed.
