The document describes the Myers-Briggs Type Indicator, a questionnaire used to determine preferences in how people perceive information and make decisions. It consists of 23 pairs of statements to choose from, with scoring based on preferences. The four scales that emerge are: Introversion/Extroversion, Sensing/Intuition, Thinking/Feeling, and Judging/Perceiving. Together they form 16 personality types that reflect differences in how people direct and receive energy, acquire information, make decisions, and orient themselves to the outer world.
