A dual-process motivational model of ideology, politics, and prejudice

There have been two broad approaches to how sociopolitical or ideological attitudes are structured. The more traditional unidimensional approach sees ideological attitudes as organized along a single left-to-right dimension, and influenced by a single coherent set of social and psychological causes, but has not been well supported empirically. During the past 2 decades evidence has increasingly suggested that there are two distinct dimensions of ideological attitudes, which seem best captured by the constructs of Right Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO). These dimensions may sometimes be strongly related, but often are not, and seem to express quite different basic values or motivational goals. This has been formalized in a dual-process motivational model of ideological attitudes, which sees RWA and SDO as originating in different social worldview beliefs, personality trait dimensions, and social environmental influences, and as influencing socio-political and intergroup behavior and outcomes in different ways and through different mechanisms. New research supporting these propositions is reviewed.
