People are strongly motivated to maintain psychological security, or equanimity, which causes them to process and act on information in ways that are favorable to protecting against anxiety (i.e., psychological "defense"). People rely on at least three interlocking mechanisms to maintain security—investment in social relationships, self-esteem, and meaningful worldviews—and these mechanisms perfuse nearly every aspect of life. By consequence, people's political beliefs, attitudes, and leadership preferences reflect motivated efforts to maintain security. Research derived from terror management theory and related theories of security maintenance shows that security needs influence political decision making in three major ways. First, they amplify people's affinity for political stances that affirm their preexisting worldviews and bolster their sense of belongingness, affiliation, and esteem. Second, security needs tend to draw people toward conservative viewpoints; however, a more potent consequence might be to harden or polarize existing political stances. Finally, security needs cause attraction to charismatic and powerful political personalities (i.e., politicians). Although the theoretical basis for these conclusions is strong, and there is research to support them, it remains challenging to apply this analysis to specific persons, situations, and political issues because it is not always clear which security-relevant facets within complex circumstances will be most salient or influential. Nevertheless, a security-based analysis of political decision making has impressive explanatory potential and helps observers to understand polarization and "tribal" tendencies in politics, among other things.
