There has been a dramatic shift from students seeking computer science degrees to those seeking information technology degrees. Students are enrolling in information technology programs in far greater numbers than those enrolling in computer science. Additionally, more students are attending nontraditional programs. Prior research has established that students are more comfortable with professors that have the same or similar personality types. The purpose of this exploratory, theory-building study was to identify if personality differences exist between professors teaching in computer science and information technology degree programs in the United States using the Myers-Briggs Type Indicator (MBTI). With the plummet of students majoring in information technology related fields and the increased demand for them in the next five to ten years, it is increasingly important for colleges and universities offering computer-related degrees to attract and retain students. It is equally important that colleges and universities attract and retain qualified computer science and information technology professors. This research may aid in solving these problems. Personality differences between computer science and information technology professors in the introverted/extraverted MBTI dichotomous personality trait were identified; no personality differences between male and female professors were identified.
