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.

What SEMalytics measures: Audience Fit Scores B2B copy against the Big Five (OCEAN) personality model (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism), the framework with 50+ years of peer-reviewed validation. MBTI is the most widely-recognized personality vocabulary in business culture, and this page uses it for that reason; the underlying measurements run on OCEAN.

The MBTI framework is one of the most widely recognized personality frameworks in business. In a survey by CPP Inc. (the MBTI publisher), over 80% of Fortune 500 companies had used MBTI for team building or leadership development (CPP Inc., 2009; this is 2009 data, and current adoption rates may differ). 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, specifically Neuroticism, that research links to risk sensitivity and purchase avoidance under uncertainty (Mooradian & Olver, 1997, Journal of the Academy of Marketing Science, 25(1), 31–42). For B2B communication improvement, you need to understand both what MBTI tells you and where it falls short.

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 in the 1940s by Katharine Cook Briggs and her daughter Isabel Briggs Myers, 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 as of 2009 (CPP Inc.).

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.

Trait legend: O = Openness, C = Conscientiousness, E = Extraversion, A = Agreeableness, N = Neuroticism (Big Five dimensions). The OCEAN mapping on each card is a directional estimate based on correlational research (McCrae & Costa, 1989), not a clinically validated score.
