1) The Myers-Briggs Type Indicator (MBTI) is the most famous. Based on the typological theory described by Carl Jung, it was created in 1943 by a mother-daughter team, Katherine Briggs and her daughter Isabel Myers. Neither Katherine nor Isabel were trained in psychology, although Katherine was a devoted reader of Dr. Jung.

Today, its used for evaluating job candidates, executive development, and even marriage counseling. The test looks at four dimensions of personality, allowing the test-taker to indicate a preference for either of the two choices on each dimension. The dichotomous dimensions are introversion/extroversion, sensing/intuition, thinking/feeling, and judging/perceiving.

Each preference is coded by a letter, and the resulting personality type will have four letters, describing a persons preference for the way they perceive the world and like to make decisions. Two examples of 16 possible personality types are ISTP: The Analyzer Operator or ENFJ: The Envisioner Mentor.

The test is so widely used that IMDB lists the personalities of fictional characters .
