The four dichotomies or preferences playing the role of dimensions in the Myers-Briggs typology are extraversion/introversion, sensing/intuitive, thinking/feeling and judging/perceiving. An individual may only be grouped in a single preference for each dimension. The Myers-Briggs uses single letters to represent each preference. For example, ENFP represents a person who has the preferences extraversion, intuitive, feeling and perceiving.
Attempts have been made to link the Big Five personality dimensions commonly used in today's personality theories to the Myers-Brigg personality types. Correlational studies have successfully linked the two except on the Big Five dimension of neuroticism. The correlations are: extraversion-extraversion, intuition-openness, feeling-agreeableness and judging-conscientiousness.
The Enneagram theory is another categorical personality theory, dividing people into nine types. Some researchers have performed correlational studies linking the Enneagram typologies to the Myers-Briggs typologies. These studies show that there is not a one-to-one or even one-to-two relationship between the Enneagram and the Myers-Briggs personality types; instead each Enneagram type is associated with a handful of Myers-Briggs personality preferences. For example, type 8 of the Enneagram theory is associated with the Myers-Briggs preferences of extraversion, thinking and judging.
Personality researcher Damon Verial has performed data analysis on the relationship between the Myers-Briggs personality types and drinking habits. He found that having a preference for extraversion or thinking significantly increases an individual's probability of being a frequent drinker. Additionally, intuitive and perceiving preferences are associated with higher rates of frequent drinking, though to a lesser degree. The Myers-Briggs type that has the highest likelihood for alcoholism is ENTP, having about a 23 percent chance of becoming a heavy drinker.
