So, what are the types of personalities? Below, I dive into four common models used to determine personality types: Myers-Briggs Type Indicator (MBTI), 16 Personalities, The Big 5 and Enneagram.

Research suggests that when MBTI preferences are evaluated as continuous dimensions, rather than split into categories, there is some correlation with scores on the Big Five traits.

The word “personality” first came into use in the 13th century, when it simply referred to being human. By the 18th century, its meaning had changed to refer to a person’s individual traits.
