# Psychology > [!info] Gateway page > Orientation and scope here; the discipline spine — subdisciplines, classic experiments, political-psychology theory, and the behavioral-biology layer — is at [[Psychology Hub]]. Psychology earns its place in a knowledge base about political power for a specific reason: most of the phenomena this vault tracks are group phenomena, and group behavior is not the sum of individual behavior. The single most robust finding in social psychology is that **situation outweighs disposition** — that ordinary people, placed in particular structural conditions, reliably produce behavior that observers attribute to character. Getting this backwards is the [[Fundamental Attribution Error]], and it is the default failure mode of political commentary. Four subdisciplines carry most of the analytical weight here. **Social psychology** supplies the intergroup machinery. [[Realistic Conflict Theory]] holds that hostility follows from actual competition over scarce resources; the [[Minimal Group Paradigm]] demonstrated the more disturbing finding that in-group favoritism appears even when the groups are assigned by coin flip and nothing is at stake. [[Social Dominance Theory]] adds the orientation dimension — the degree to which an individual endorses group-based hierarchy — which turns out to be measurably distinct from authoritarian submission and to predict different things. [[Relative Deprivation]] explains why grievance tracks *perceived* position rather than absolute condition, which is why prosperity does not reliably purchase political stability. **Political psychology** is the applied layer: how identity, threat, and motivated reasoning shape political judgment. Its central and least comfortable finding is that political belief functions substantially as group identification rather than as considered policy preference, which is why correcting the factual record so often fails to move anything. [[Identity-Protective Cognition]] names the mechanism — reasoning deployed in defense of standing within a valued group, and doing so more effectively the more numerate and better-informed the reasoner is. **Clinical psychology** contributes the vocabulary for leader pathology, and does so with an explicit hazard attached. [[Narcissistic Personality Disorder]], [[Malignant Narcissism]], and the [[Dark Triad]] constructs are genuinely useful descriptive frames for behavior patterns. They are not diagnoses, and this vault does not offer them as such — see [[Goldwater Rule]] for the professional norm and the argument around it. The material lives under [[Narcissism Hub]] with that caveat attached at the top. **Behavioral biology** supplies the substrate: stress physiology via the [[HPA Axis]], the developmental arc of the Prefrontal Cortex, and Sapolsky's [[Forest Troop Study]] — the accidental natural experiment in which a baboon troop lost its most aggressive males and sustained a markedly less brutal social culture for decades afterward, transmitted through acculturation rather than genes. That study does more work than its size suggests: it is one of the cleanest available demonstrations that hierarchy-and-aggression equilibria are cultural and therefore movable. The classic experiments — Asch on [[Conformity]], Milgram on obedience, Zimbardo's prison study — remain foundational, but should be carried with their replication caveats intact. Zimbardo's in particular has been substantially reassessed; the vault treats it as a historically important demonstration with serious methodological problems rather than as settled evidence. Where a finding has weakened, that belongs on the page. ## Where to go from here | Destination | What's there | |---|---| | [[Psychology Hub]] | The full spine: subdisciplines, classic experiments, political-psychology theory, behavioral biology | | [[Narcissism Hub]] | Clinical constructs applied to leadership, with the diagnosis caveat | | [[Social Dominance Theory]] · [[Realistic Conflict Theory]] · [[Relative Deprivation]] | The intergroup-conflict theories | | [[Dehumanization]] · [[Infrahumanization]] · [[Delegitimization]] | The mechanisms that precede violence | | [[Conformity]] · [[Deindividuation]] · [[Pluralistic Ignorance]] | Why groups do what individuals wouldn't | | [[Crowd Psychology]] | The mass-behavior tradition, Le Bon onward | | [[Decision Science]] | The judgment-and-choice side of the same terrain | ## See also [[Authoritarianism]] · [[Cults]] · [[Propaganda]] · [[Groupthink]] · [[Confirmation Bias]] · [[Political Psychology]]
