There are 16 personality types identified by Myers-Briggs. The types either start with an E for extroversion or an I for introversion. For example, an ESTP personality type stands for extroversion, sensing, thinking and perceiving. An ISTP has the same personality types with the exception of being introverted rather than extroverted.
Other Myers-Briggs personality types include ENTJ and INTJ. These types stand for extroversion (or introversion), intuition, thinking, and judging, ENTJ personalities tend to be organized and strong planners. INTJ personalities tend to be determined and insightful. The letter F stands for feeling and is found in both extroversion and introversion personality types.
The Myers-Briggs process to discovering your personality type involves a series of multiple choice questions. The process is not a test, and there are no right or wrong answers. The questions can be answered using a paper format or online. Responses to the questions are scored, and the resulting four-letter personality type is determined based upon the score.
The Myers-Briggs formula is described as a shorthand way to discovering a person's four mental functions and preferences. The Myers-Briggs personality assessment is most frequently used in work environments and to help determine career paths. The results are typically kept confidential.
