The article, published in Teaching and Learning in Medicine, aims to determine (a) changes in Myers-Briggs Type Indicator (MBTI) profiles of medical students over time, (b) gender profile differences and effects of more women in medical school, (c) associations between type and career choices. The data shows that the type distribution of physicians is fairly similar to that in the 1950s, although there has beEn a trend toward more judging types. Women, introverted and feelings types are more likely to prefer primary care specialties. On the other hand, male, extroverted, and thinking types choose surgical specialties. The data synthesized further in this paper develops an understanding of how some aspects of personality relate to specialty choice.
