TL;DR: The core ideology of conservatism stresses resistance to change and justification of inequality and is motivated by needs that vary situationally and dispositionally to manage uncertainty and threat.

TL;DR: System-justification as discussed by the authors is a psychological process that contributes to the preservation of existing social arrangements even at the expense of personal and group interest, and it is argued that the notion of justification is necessary to account for previously unexplained phenomena, such as the participation by disadvantaged individuals and groups in negative stereotypes of themselves, and the consensual nature of stereotypic beliefs despite differences in social relations within and between social groups.

TL;DR: This paper reviewed and integrated 10 years of research on 20 hypotheses derived from a system justification perspective, focusing on the phenomenon of implicit outgroup favoritism among members of disadvantaged groups (including African Americans, the elderly, and gays/lesbians) and its relation to political ideology.

TL;DR: This review examines recent theory and research concerning the structure, contents, and functions of ideological belief systems and considers the consequences of ideology, especially with respect to attitudes, evaluations, and processes of system justification.

TL;DR: Studies reveal that there are indeed meaningful political and psychological differences that covary with ideological self-placement and are useful for understanding the political divide between "red states" and "blue states".
