The MBTI is a system that describes sixteen personality types based on Carl Jung's theories on introverts, extraverts, intuitives, sensors, feelers and thinkers. The MBTI also adds a new dimension: Judging and Perceiving, loosely based on Carl Jung's theories on rational and irrational personality types.
Introversion and Extraversion
An introvert was described to have a preference for the inner world, and what happened inside, for example our thoughts, memories, and subjective experiences. For example, a premonition, an idea, mental reasoning, introspection.
An extravert was instead said to be more interested in the outer world, and what happens around us. Sounds, noises, people, surprises, possibilities, mysteries, strange events, nature and animals. So called "objective experiences".
Intuition and Sensing
The intuitive type could be described as the creative, idea-driven, freedom loving type. A lover of change, patterns, curiosities, mystery and strange and peculiar experiences.
The sensor is often portrayed as the conservative, traditional, experience driven type. A lover of reality, action, life, and what nature and experience can teach us.
Feeling and Thinking
A feeling type draws meaning from experiences, qualities, nuances, people, different perspectives. What do people think and believe and what stories do they follow?
A thinking type draws meaning from data, facts, objective information. For example what can be measured, observed, or studied logically. What we can reason to be the case.
Judging and Perceiving
Judging types tend to draw control and power from planning, strategy, long-term thinking, discipline, focus, and independent or principled action.
Perceiving types tend to draw control from adaptation, ideas, options, possibilities, action, change, and responding to interruptions and changes.
