The Authoritarian Personality – An Overview
The first usage of the term "authoritarian personality" goes back to Abraham Maslow in 1943, whose work in turn rests upon Erich Fromm's theory of the authoritarian character. Else Frenkel-Brunswik began to publish articles in prominent psychological journals, focusing mostly on personality and motivation. It was during this time that there came a big push fro the psychological world to try and figure out exactly how World War Two came about. More specifically, the push was to figure out how the Nazi's could have committed such horrible atrocities.
Frenkel-Brunswik joined forces with Nevitt Stanford and Daniel Levinson to design and launch studies of anti-Semitism. In 1945, the American Jewish Committee supported the expansion on these studies, and Theodor Adorno joined in their research. Their research was published in 1950 in the book The Authoritarian Personality. They characterized the authoritarian personality syndrome as a weak and dependent person who sacrifices their identity of the self in order to maintain a precarious sense of safety and order. Most people with this syndrome grow up in very strict households where the rules are followed to the letter and there are very strict punishments for any rule breaking. These people grow up and internalize these very strict moral beliefs, and that strict obedience to these moral codes leaves them feeling very insecure when they can not live up to the high standards that they have set for themselves. In their worlds, strength and power are seen as good traits and everything else is a sign of weakness. There is a direct correlation between having this syndrome and having a strong prejudice against out-groups.

As an instrument to measure this outlook, the AS-scale (for "anti-Semitism") the E-scale (for "Ethnocentrism") and the PEC-Scale (for "political-economic conservatism") are used.

The instrument for assessing the underlying authoritarian personality structure was the so-called F-Scale ("implicit antidemocratic tendencies and fascist potential"). This scale is comprised of the following subscales:

• 
  Conventionalism -- the tendency to accept and obey social conventions and the rules of authority figures; adherence to the traditional and accepted
  
• 
  Authoritarian Submission -- submission to authorities and authority figures
  
• 
  Authoritarian Aggression -- an aggressive attitude towards individuals or groups disliked by authorities; particularly those who threaten traditional values
  
• 
  Anti-Intraception -- rejection of the subjective, imaginative and aesthetic
  
• 
  Substitution and Stereotypy -- superstition, cliché, categorization and fatalistic determinism
  
• 
  Power and Toughness -- identification with those in power, excessive emphasis on socially advocated ego qualities
  
• 
  Destructiveness and Cynicism -- general hostility, putting others down
  
• 
  Projectivity -- the tendency to believe in the existence of evil in the world and to project unconscious emotional impulses outward
  
• 
  Sex -- exaggerated concerns with respect to sexual activity
  

Quotes by Erich Fromm:
It seems that nothing is more difficult for the average man to bear than the feeling of not being identified with a larger group.

The fear of isolation and the relative weakness of moral principles help any party to win the loyalty of a large sector of the population once that party has captured the power of the state.

The individual's greatest strength is based on the maximum of integration of his personality, and that means also on the maximum of transparence to himself. "Know thyself" is one of the fundamental commands that aim at human strength and happiness.
The ordinary man with extraordinary power is the chief danger for mankind--not the fiend or the sadist. Once the living human being is reduced to a number, the true bureaucrats can commit acts of utter cruelty, not because they are driven by cruelty of a magnitude commensurate to their deeds, but because they feel no human bond to their subjects. While less vile than pure sadists, the bureaucrats are more dangerous, because in them there is not even a conflict between conscience and duty; their conscience is doing their duty; human beings as objects of empathy and compassion do not exist for them.

intellectualization, quantification, abstractification, bureaucratization, and reification--the very characteristics of modern industrial society, when applied to people rather than to things, are not the principles of life but those of mechanics. People living in such a system become indifferent to life and even attracted to death. If it is true, as I have tried to show, that love is the only sane and satisfactory answer to the problem of human existence, then any society which excludes, relatively, the development of love, must in the long run perish of its own contradiction with the basic necessities of human nature.

The fact that millions of people share the same vices does not make these vices virtues, the fact that they share so many errors does not make the errors to be truths, and the fact that millions of people share the same forms of mental pathology does not make these people sane. It follows...that mental health cannot be defined in terms of the "adjustment" of the individual to his society, but, on the contrary, that it must be defined in terms of the adjustment of society to the needs of man, of its role in furthering or hindering the development of mental health.
"To be alive" is a dynamic, not a static, concept. Existence and the unfolding of the specific powers of an organism are one and the same. All organisms have an inherent tendency to actualize their specific potentialities. The aim of man's life, therefore, is to be understood as the unfolding of his powers according to the laws of nature.
