Frequently Asked Questions
Have another question? Let us know.
What is the MBTI?
The Myers-Briggs Type Indicator (MBTI) is a personality questionnaire based on Jung's theory of psychological types. It sorts people into 16 four-letter types along four dimensions: Extraversion-Introversion, Sensing-Intuition, Thinking-Feeling, and Judging-Perceiving.
Is the MBTI scientifically reliable?
The MBTI is popular but has limited scientific support: test-retest reliability is moderate, and its type-based scores don't map cleanly onto traits. Research psychology generally prefers dimensional models such as the Big Five, which correlate with MBTI dimensions. This test is offered for education and self-reflection.
What do the four letters in my type mean?
Each letter reflects your preference on one dimension: E or I (where you direct energy), S or N (how you take in information), T or F (how you decide), and J or P (how you approach the outside world). Preferences are tendencies, not absolute categories.
Can my MBTI type change?
Many people get a different type when they retake the MBTI, especially on dimensions where their preference is near the middle. It's healthier to read your result as describing current preferences than as a fixed identity.
