Myers-Briggs Type Indicator® (MBTI®)

The Myers-Briggs Type Indicator® (MBTI®) assessment has helped millions of people worldwide gain insights about themselves and how they interact with others—and improve how they communicate, learn, and work. It provides a powerful framework for building better relationships, driving positive change, harnessing innovation, and achieving excellence. The MBTI assessment makes Carl Jung's theory of psychological type both understandable and highly practical by helping individuals identify their preferences in four areas (see graphic below).
