An Introduction to the Eysenck Theory of Three Factors

Hans Eysenck (1916-1997) developed a very influential trait theory of personality, which has successful infiltrated the public mindset with regards to how we think about personality in day-to-day life.

Using factor analysis to devise his theory, Eysenck (1947, 1966) identified three factors of personality: extroversion, neuroticism and psychoticism.

Each of the Eysenck Theory factors is a bipolar dimension, meaning that each has a direct opposite:

  • Extroversion vs. Introversion
  • Neuroticism vs. Emotional Stability
  • Psychoticism vs. Self-Control (added to the model in 1966)

It is worth noting that Eysenck’s use of the term ‘psychoticism’ differs from how most clinical psychologists would use the word. Eysenck is referring to anti-social behaviours, not a mental illness.
