Ingroup identification, hope and system justification: Testing hypothesis from social identity model of system attitudes (SIMSA) in a sample of LGBTQIA+ individuals

The social identity model of system attitudes (SIMSA) suggests that system justification among low-status groups can be explained by ingroup identification and the hope for a collective future improvement. In this report, we summarize the results of a cross-sectional investigation concerning the relationship between system justification, hope and identification based on a sample of 200 LGBTQIA+ individuals (identifying themselves as non-normative with respect to gender identity and sexual orientation). The results were supportive of SIMSA expectations and showed that system justification was positively linked to hope for future advancement. Importantly, hope played a key role influencing the relations between ingroup identification and perceived ingroup status: for low-status individuals who had high hope, ingroup identification was positively associated with system justification. Limits are acknowledged.
