The science of personality

The Myers-Briggs Type Indicator® is the most widely used personality assessment in the world. First developed by Isabel Briggs Myers and her mother Katharine Cook Briggs, the MBTI assessment brings Jungian theory to life in a way that is practical, powerful, and endlessly applicable.

Our tools are used by Fortune 500 companies, universities, coaches, and individuals in over 115 countries. We hold ourselves to the highest standards of psychometric research — continuously validating and refining our assessments against real-world data.

We are a Certified B Corporation, meaning we meet rigorous standards of social and environmental performance, accountability, and transparency.
