All 16 MBTI® Personality Types Explained

How each of the 16 MBTI® types naturally communicates — and what they miss. Understand your default style, then translate to the Big Five for complete buyer coverage.

The MBTI framework is one of the most widely recognized personality frameworks in business. Over 80% of Fortune 500 companies have used it for team building or leadership development. Its 16 types give people a shared language for talking about personality differences.

But MBTI was designed for self-understanding, not for predicting how buyers respond to messaging. It captures four personality dimensions while missing a fifth — Neuroticism — that strongly predicts buying behavior under uncertainty. For B2B communication improvement, you need to understand both what MBTI tells you and where it falls short.

How to Use This Section

Find your MBTI type below to understand your natural communication strengths and blind spots. Then use the MBTI-to-OCEAN translator to see your full Big Five profile — including the Neuroticism dimension MBTI cannot measure. For the deepest analysis, paste a writing sample into COS and see how your actual text scores across all five dimensions.

What Does MBTI Stand For?

MBTI stands for Myers-Briggs Type Indicator, a personality framework based on Carl Jung's theory of psychological types. Developed by Katharine Cook Briggs and her daughter Isabel Briggs Myers in the mid-20th century, the MBTI assessment has become one of the most widely used personality instruments in the world, with over 2 million people taking it each year.

The MBTI® assessment sorts people into 16 personality types based on four preference dimensions:

  • Extraversion (E) / Introversion (I) — where you direct your energy
  • Sensing (S) / Intuition (N) — how you take in information
  • Thinking (T) / Feeling (F), how you make decisions
  • Judging (J) / Perceiving (P), how you approach the outside world

Each combination produces a four-letter type code (like INTJ or ENFP) that describes a person's natural preferences across these four dimensions. While MBTI is valuable for self-awareness and team building, it measures four of the five core personality dimensions identified by modern psychology. The fifth dimension, Neuroticism (emotional reactivity and risk sensitivity), requires the Big Five (OCEAN) model to measure.
