About 16 Types Personality Test

The 16 Types Personality Test is an introspective self-report questionnaire designed to identify psychological preferences in how individuals perceive the world and make decisions. Developed from concepts introduced by Carl Jung and later expanded by Katharine Cook Briggs and Isabel Briggs Myers, the framework categorizes personality into distinct, structured types.

The theory proposes that people experience the world through four primary psychological functions—sensation, intuition, feeling, and thinking—and that one of these functions tends to dominate. Combined with attitudes such as extraversion or introversion and lifestyle preferences like judging or perceiving, these traits form sixteen unique personality types.

Based on Established Psychological Theory

The 16 Types Personality Test draws from Carl Jung’s theory of psychological types. It evaluates four key dichotomies:

Extraversion (E) or Introversion (I)

Sensing (S) or Intuition (N)

Thinking (T) or Feeling (F)

Judging (J) or Perceiving (P)

These combinations result in sixteen distinct personality types, each reflecting consistent behavioral patterns and cognitive preferences.

The 16 Personality Categories

The personality types are grouped into four broader categories:
