Daniel J. Levinson (May 28th, 1920 – April 12th, 1994), a Jewish psychologist most well-known for his theory of stage-crisis view responsible for ‘normalising’ the concept of the ‘midlife crisis’. Levinson was born in New York City, New York. He began his studies at the University of California, Berkeley, whereat he completed his dissertation in 1947. Following this, Levinson conducted research on personality, specifically constructing the fiction of ‘authoritarian personalities’ at Berkeley and Western Reserve University. With collaboration from Theodor W. Adorno and Else Frenkel-Brunswik “The Authoritarian Personality,” was published in 1950. The main component of this hypothesises a personality type with a susceptibility “to anti-Semitic ideology and anti-democratic political beliefs.” Like all Jewish Marxist theories it must be able to label, file or define personality types by ranking and rating various individual traits in order to reduce it to a directed multiple choice form. This was achieved using the ‘F-scale personality test’ (also see Chutzpah).
