"Psychological type" redirects here. See Psychological Types for the work by Jung.

The concept of personality type refers to the psychological classification of different types of individuals. Personality types are sometimes distinguished from personality traits, with the latter embodying a smaller grouping of behavioral tendencies.^[1] Types are sometimes said to involve qualitative differences between people, whereas traits might be construed as quantitative differences.^[2] According to type theories, for example, introverts and extraverts are two fundamentally different categories of people. According to trait theories, introversion and extraversion are part of a continuous dimension, with many people in the middle. While typologies of all sorts have existed throughout time the most influential idea of psychological types originated in the theoretical work of Carl Jung, published as Psychological Types in 1921. Other typologies such as Socionics, MBTI, and Keirsey Temperament Sorter all have roots in Jungian philosophy.

[edit] Usage

One well known example of personality types is Type A theory. According to this theory, impatient, hostile people are classified as Type A, whereas calm, laid back individuals are designated as Type B. The theory originally suggested that Type A individuals were more at risk for heart attacks, but this claim has not been supported by empirical research.^[3]

Developmental psychologist Jerome Kagan is a prominent contemporary advocate of type theory. He suggests that shy, withdrawn children are best viewed as having an inhibited temperament, which is qualitatively different from other children.^[4]

As a matter of convenience, trait theorists sometimes use the term "type" to describe someone who scores exceptionally high or low on a particular personality trait. Hans Eysenck refers to superordinate personality factors as types, and more specific associated traits as traits.

Several pop psychology theories (e.g., Men Are From Mars, Women Are From Venus, the enneagram) rely on the idea of distinctively different types of people.

[edit] Criticism

The term "type" has not been used consistently in psychology and has become the source of some confusion. Furthermore, because personality test scores usually fall on a bell curve rather than in distinct categories,^[5] personality type theories have received considerable criticism among psychometric researchers. One study that directly compared a "type" instrument (the MBTI) to a "trait" instrument (the NEO PI) found that the trait measure was a better predictor of personality disorders.^[6] Because of these problems, personality type theories have fallen out of favor in psychology. Most researchers now believe that it is impossible to explain the diversity of human personality with a small number of discrete types. They recommend trait models instead, such as the five factor model.^[7][8][9]
