Have you ever heard someone describe themselves as an INTJ or an ESTP and wondered what those cryptic-sounding letters could mean?
What these people are referring to is their personality type based on the Myers-Briggs Type Indicator (MBTI).
The Myers-Briggs Personality Type Indicator was designed to identify a person's personality type, strengths, and preferences. The questionnaire was developed by Isabel Myers and her mother Katherine Briggs based on their work with Carl Jung's theory of personality types. Today, the MBTI inventory is one of the most widely used psychological instruments in the world.
