The Eysenck Personality Inventory. (1964),
by H. J. Eysenck, S. B. G. Eysenck
H.J. Eysenck was a psychologist known for his work in personality theory, intelligence, and behavior. He authored several influential books on topics such as temperaments, personality, and psychology, including "Dimensions of Personality" and "The Structure of Human Personality." Eysenck was also known for his research on the biological bases of personality and behavior.
Eysenck's Personality Inventory (EPI) is a self-report questionnaire that measures personality traits such as extraversion, neuroticism, and psychoticism using a binary response format. Eysenck's Personality Questionnaire (EPQ) is an updated version of the EPI that includes additional scales and uses a Likert scale response format. The EPQ provides a more detailed assessment of personality compared to the EPI.

Eysenck is to do with psychology not maths and he developed the ideas of personality types of extroversion introversion and neuroticism think again...
The personality type of an unstable extrovert.
Hippocrates and Carl Jung
Hans Eysenck's personality theories was based on three universal traits. The degree of introversion/extroversion, moodiness or even temperedness he called neuroticism/emotional stability and psychoticism.
Eysenck's theory was that genetic factors have a greater impact on subsequent behavior than childhood or life experiences do in general. Meaning that the experiences that we have in life, especifically in our childhood have little to do with the development of our personality.
Hans Eysenck and the many followers after his death are not taking into account modern research findings. Wikipedia describes many contradictory personality traits. All except one (Enneagram) recognize the effect of the situational environment of the person. Healthy people are sensitive to their environments. Most personality theories ignores the sociological factors, as well as the psycho-medical situation of the person.
Michael Eysenck was born in 1944.
