Extroverts are more likely to perceive themselves as good communicators than are Introverts, a study led by Donald Loffredo at the University of Houston has found. In this survey of communication style and personality type, researchers discovered significant correlations between various aspects of communication and the preference scales of Extroversion/Introversion, as well as Thinking/Feeling and Sensing/Intuition.
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.
In a survey of Brazilian software engineering students, Introverted personality types were found to dominate heavily. This should be no surprise to anyone familiar with personality type; Introverts are more likely to enjoy careers that allow them to work independently, keep a low profile, and accomplish projects on their own. Types of ISFP, INTP, and ESTP were over-represented among the population of software engineers.
A national survey of real estate agents conducted by Douthit Communications, Inc., found that 75% of agents are Extraverted Judgers, three times the percentage of Extraverted Judgers in the population as a whole. The sample consisted of mostly seasoned agents, and researchers were not clear whether Extraverted Judgers are more likely to choose real estate, or whether they are the types most likely to succeed in the industry.
