The authoritarian personality is an influential theory of personality developed by University of California, Berkeley psychologists, Theodor W. Adorno, Else Frenkel-Brunswik, Daniel Levinson, and Nevitt Sanford in their 1950 book of the same name. The personality type is defined by nine traits that were believed to cluster together as the result of psychodynamic, childhood experiences. These traits are conventionalism, authoritarian submission, authoritarian aggression, anti-intraception, superstition and stereotypy, power and "toughness," destructiveness and cynicism, projectivity, and exaggerated concerns over sexuality. In brief, the authoritarian is predisposed to follow the dictates of a strong leader and traditional, conventional values.
