Big-Five personality prospectively predicts Social Dominance Orientation and Right-Wing Authoritarianism

A full cross-lagged panel design examined the bidirectional effects of the Big-Five personality dimensions on Social Dominance Orientation (SDO) and Right-Wing Authoritarianism (RWA) over 9 months (N = 190 undergraduates). Consistent with the Dual Process Cognitive-Motivational Model, SDO and RWA exhibited markedly different personality bases. Low Agreeableness predicted change in the motivational goal for group-based dominance and superiority (SDO), whereas Openness to Experience predicted change in the motivational goal for social cohesion and collective security (RWA). Extending previous longitudinal research, this study indicates that the effect of personality on ideology is unidirectional, as RWA and SDO did not predict reciprocal prospective change in broad-bandwidth personality. These findings are consistent with a model in which relatively stable broad-bandwidth personality traits shape ideological attitudes over even relatively short time periods, and not the reverse.
