The authoritarian personality
In the review of references consulted, the study on the authoritarian personality by Theodor Adorno, Else Frenkel-Brunswick, Daniel Levinson and Nevitt Sanford, published in 1950, must be mentioned in second place (Adorno et al., 1969). The Berkeley group arrived at the conclusion that there are certain characteristics common to every person receptive to fascist propaganda. These people, it was postulated, must have the same mental structure, described as ethnocentric and prone to prejudice. The authoritarian mental structure is contrasted with the liberal one, which is defined by the opposite characteristics, i.e. non-ethnocentric, unprejudiced and unreceptive to fascist propaganda.
