Over the past 70 years, the MBTI® instrument has helped millions of individuals throughout the world gain insights about themselves and how they interact with others – enabling personal transformation by improving how they communicate, learn, and work. It provides a powerful framework toward building better relationships, driving positive change, harnessing innovation, and achieving excellence.

In developing the MBTI® instrument, Carl Jung’s theory of psychological type is made both easily understandable and practical to people’s everyday lives. The essence of the theory is that much seemingly random variation in behaviour is actually quite orderly and consistent, owing to basic differences in the ways individuals are oriented toward the external world, take in information and draw conclusions about what they perceive.
