Who created the Myers Briggs Test?

The Myers-Briggs Type Indicator (MBTI) was developed by two women, Katharine Cook Briggs and her daughter, Isabel Briggs Myers. They created the test based on Carl Jung's theory of psychological types, which identified eight personality types. Although neither Briggs nor Myers were scientists or psychologists, they were influenced by Jung's ideas and expanded his eight types into 16 distinct personality traits 1 2.
