In the July 1980 edition of MBTI News, Briggs Myers attributed another reason for creating the MBTI to her marriage to Clarence Myers. Their differences in perceived psychological types inspired her mother, Katharine Cook Briggs, to keep studying differences among people and their actions. Her mother had come upon the work of Carl Gustav Jung and introduced it to her daughter who then started studying the psychological types. 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. This included about 5,500 students and Briggs Myers studied it for years by looking at patterns among dropouts and successful students. In 1975, Briggs Myers co-founded the Center for Application of Psychological Type with Mary McCaulley. CAPT is a non-profit organization run by the Myers & Briggs Foundation, which maintains research and application of the MBTI, also existing to protect and promote Briggs Myers' ideology. Its headquarters are in Gainesville, Florida and its motto is "Fostering human understanding through training, publishing, and research". , according to the Myers & Briggs Foundation, "research on the MBTI instrument has continued into the present, with dozens of articles published each year." The Isabel Briggs Myers Memorial Research Awards exist to further MBTI and psychological research. These awards are given twice a year, consisting of $2,000 for up to two people. Most of the research supporting the MBTI's validity has been produced by CAPT and published in the center's own journal, the Journal of Psychological Type, raising questions of independence, bias, and conflict of interest. , although the MBTI is widely used by businesses, coaches and psychologists, the MBTI has been found to have significant validity issues, and is not widely endorsed by academic researchers in psychology, often dismissed as pseudoscience.
