This is a free MBTI-style type indicator based on the same Jungian framework. The official MBTI® instrument is a trademark of The Myers-Briggs Company and is administered by certified practitioners for a fee (typically $50 or more). Our 60-question version uses the same four-dichotomy methodology and is free to take with no account required; your four-letter type appears on screen and the detailed report is part of Premium. It's designed to give you an accurate, useful read on your type, not to replace a paid certified assessment if your employer specifically requires one.

Each letter is one side of a preference pair. I/E (Introversion vs Extraversion), where you get your energy: from inner reflection or from interaction. S/N (Sensing vs Intuition), how you take in information: through concrete facts and details, or patterns and possibilities. T/F (Thinking vs Feeling), how you decide: through logic and consistency, or values and impact on people. J/P (Judging vs Perceiving), how you handle the outside world: planned and structured, or flexible and open-ended. Combine one from each pair and you get your 4-letter type, such as ENFP or ISTJ.

There are 16 MBTI personality types, formed by combining the four preference pairs (I/E, S/N, T/F, J/P). Each of the 16 combinations creates a distinct profile with its own typical strengths, communication style, and career leanings, from the analytical INTJ to the people-focused ESFJ.

Beneath the 4-letter code sits a 'function stack', the deeper engine of MBTI. Jung described eight cognitive functions (Introverted/Extraverted versions of Intuition, Sensing, Thinking, and Feeling), and each type uses four of them in a characteristic order: a dominant, an auxiliary, a tertiary, and an inferior. For example, INTJ leads with Introverted Intuition (Ni) supported by Extraverted Thinking (Te). Functions explain why two people of the same type can feel different, and why your type can deepen with age as you develop your lower functions.
