The Myers-Briggs Type Indicator (MBTI) is one of the world's most widely used personality assessments.

It categorizes individuals into one of 16 personality types based on their preferences across four key dimensions. But what exactly does the MBTI measure, and how can knowing your personality type be useful?

This guide breaks down the Myers-Briggs framework's origins, validity, and applications for understanding personality.

What is the Myers-Briggs Type Indicator, and Why Does it Matter?

Based on Swiss psychiatrist Carl Jung's theory of psychological types, the mother-daughter team Isabel Briggs Myers and Katharine Cook Briggs created the MBTI personality questionnaire in the 1940s. It aims to measure how people perceive the world and make decisions, classifying them into 16 distinct personality types.

Understanding your MBTI type can provide a framework for self-awareness and personal development by helping you recognize your natural strengths and potential areas for growth. It has been widely used in career counseling, relationship counseling, leadership training, and more. With over 2 million annual assessments, the MBTI remains one of the most popular models for understanding personality and behavior.

The 4 Dimensions of Personality Measured by the MBTI

The MBTI categorizes personality type based on four key dichotomies, each representing two opposing preferences:

1. Extraversion (E) vs Introversion (I): This scale measures whether you draw energy from external interactions and stimuli (extraversion) or internal ideas and reflections (introversion).

2. Sensing (S) vs Intuition (N): This scale determines whether you tend to focus on concrete sensory details (sensing) or interpret things symbolically and focus on the “big picture” (intuition).

3. Thinking (T) vs Feeling (F): This scale identifies whether you typically make judgments based on objective logic (thinking) or subjective values and emotions (feeling).

4. Judging (J) vs Perceiving (P): This measures whether you prefer structure and decisiveness (judging) or flexibility and spontaneity (perceiving).

What Do the 16 MBTI Personality Types Mean?

Combining each of the four preferences, the MBTI defines 16 personality types denoted by four letters. For example, someone with preferences for Introversion, Sensing, Thinking, and Judging would have the type ISTJ.

The 16 types are ISTJ, ISFJ, INFJ, INTJ, ISTP, ISFP, INFP, INTP, ESTP, ESFP, ENFP, ENTP, ESTJ, ESFJ, ENFJ and ENTJ. Each type has its strengths, weaknesses, and tendencies that can impact personal and work behavior.

For example, INTJs are analytical strategists, ESFPs are spontaneous entertainers, ISFJs are diligent caretakers, and ENTPs are inventive thinkers. While MBTI types do not predict specific behaviors, they can illuminate broad patterns in how different personalities process the world.

Is the Myers-Briggs Type Indicator Scientifically Valid and Reliable?

Given the MBTI’s popularity, significant research has examined its psychometric validity and reliability. Much debate exists around how well it measures what it aims to do. While newer Big Five measurements like the NEO-PI are considered more empirically sound, many studies demonstrate respectable validity and reliability for the MBTI.

However, the MBTI remains vulnerable to participant subjectivity and changes over time. One key criticism is that dichotomizing continuous personality traits into binary categories oversimplifies the complexity of human personality. Ultimately, the MBTI remains best used as a framework for personal growth rather than a conclusive diagnosis. It should complement, not replace, professional counseling.

How Can I Learn My MBTI Personality Type?

If you want to discover your MBTI personality type, you can take the official assessment from The Myers & Briggs Foundation online or from a certified practitioner. The 93-question assessment calculates your likely preferences and 4-letter type based on your responses.

Remember that the MBTI measures preferences, not skills or abilities, and that all preferences are equally valid and beneficial in the appropriate contexts. Rather than putting people in boxes, the MBTI aims to provide an empowering language for understanding similarities and differences among personality types.

Applying the MBTI: Using Personality Type to Improve Your Life

Once you have your MBTI-type results, what next? Here are some of the key applications of the Myers-Briggs framework:

Career development: Identify suitable careers that align with your natural preferences. For example, introverted types may prefer slower-paced roles focused on depth.

Communication: Recognize how you can flex your communication towards others’ preferences. For example, sensing types prefer concrete details.

Relationships: Understand compatibility among personality differences and avoid misinterpreting behaviors.

Personal growth: Consider developing aspects less comfortable for your type. For example, thinkers practicing emotional awareness.

Team dynamics: Harness strengths of different types and minimize “blindspots” when working in groups.

While imperfect, the MBTI provides a productive starting point for investigating the captivating diversity of human personality. Illuminating how fundamental inclinations take shape empowers us to understand ourselves and each other better.
