Social Identity Explanations of System Justification: Misconceptions, Criticisms, and Clarifications – Supplementary Document

This document supplements our reply to Jost et al.’s (2023) rejoinder to our initial article on the social identity model of system attitudes (SIMSA; Rubin et al., 2023). We respond to issues that we did not address in our main reply. Specifically, we argue that: (1) like SIMSA, Tajfel (1981) considered general, non-ideological, psychological processes; (2) system justification theory also refers to general, non-ideological, social psychological processes; (3) Jost et al. confuse respecting people with respecting people’s beliefs; (4) SIMSA proponents do not ignore system justification theory’s three motives; and (5) SIMSA may help to explain Osborne et al.’s (2019) results. In addition, (6) we apologise if we mischaracterised some researchers’ theoretical affiliations, and we respond to Jost et al.’s (7) questions about ideology; (8) criticisms of Owuamalam et al.’s (2016) work; and (9) criticisms about the validity of Owuamalam and Spears’ (2020) pupil dilation measure.
