This document provides an overview of personality types including: - Definitions of personality as a unique set of relatively stable traits and characteristics. - Descriptions of introverts who gain energy from alone time versus extroverts who gain energy from social interaction. - An overview of the Myers-Briggs Type Indicator (MBTI) personality assessment which categorizes preferences in four dichotomies: Extraversion vs Introversion, Sensing vs Intuition, Thinking vs Feeling, and Judging vs Perceiving. - Clarification that the MBTI assessment indicates inborn preferences on a spectrum rather than absolute types.
