Does Jack Black have “a lot of personality”? Yes, you might say that. But if you did, you would not be using the word “personality” in the same way that it is used in personality psychology. In the scientific field, “personality” does not mean “charisma”—as it does when we say that someone has “a lot” of personality. It refers to people’s distinctive and relatively consistent patterns of feeling, thinking, and behaving, and the inner psychological qualities that contribute to those consistent patterns.
