A study conducted with Temple University medical students and led by Judith Katz found that personality preferences correlated with the students' choice of medical specialty.
Surgery and Psychiatry were more often chosen by Introverts, whereas Extroverts were more likely to choose Obstetrics and Gynecology. Family Medicine and Psychiatry were popular with Intuitives. Thinking types more often chose to specialize in Internal Medicine, Surgery, Emergency Medicine, and Radiology, while Feelers were more likely to choose Ob/Gyn. Many of the specialties were dominated by Judgers, including Pediatrics, Anesthesiology, and Orthopedics; the only specialty where Perceivers were the majority was in Psychiatry.
