David Keirsey’s four temperaments, from his book Please Understand Me, are related to personality types. He takes the 16 types and simplifies them into 4 temperaments by dividing the S side of the chart into J’s and P’s and the N side into F’s and T’s. The following chart shows how Keirsey’s four temperaments relate to some other typologies as well as to characters from popular culture.
