About Isabel Briggs Myers
Isabel Briggs Myers was an American writer who co-created the pseudoscientific personality test known as the Myers–Briggs Type Indicator (MBTI) with her mother, Katharine Cook Briggs. The MBTI is one of the most-often used personality tests worldwide; over two million people complete the questionnaire each year. Isabel Briggs Myers typed herself as an INFP (Mediator). In 1945, the dean of the George Washington School of Medicine allowed Briggs Myers and her mother to apply the MBTI to first-year undergraduates. In 1975, Briggs Myers co-founded the Center for Application of Psychological Type with Mary McCaulley. Her novel Murder Yet to Come won the contest and was published periodically in the monthly magazine The Smart Set (which had absorbed McClure's in March 1929) between August 1929 and January 1930. She then created a paper survey which would eventually become the MBTI.
