“…However, unlike Beierlein, Kemper, et al (2014a), who found small positive associations of Openness and Conscientiousness with interpersonal trust, we found zero correlations for both the UK and Germany. With regard to internal locus of control, optimismpessimism, and external political efficacy, we could replicate the findings of the German-language source version: Consistent with previous findings, including those of Beierlein, Kemper, et al (2014a), we found-for both the UK and Germany-stable small-to-medium positive relations with internal locus of control (e.g., Massari & Rosenblum, 1972;Stimpson & Maughan, 1978), optimism (e.g., Mealy, Stephan, Mhaka-Mutepfa, & Alvadoro-Sanchez, 2015;Schweer, 2006), and external political efficacy (e.g., Koller, 1992;Schiffman et al, 2010;Schyns & Koop, 2010). Individuals high in optimism and external political efficacy had a higher propensity for interpersonal trust.…”
