The document discusses the Myers-Briggs Type Indicator (MBTI), a psychometric questionnaire used by many companies to measure psychological preferences. The MBTI assesses individuals on four dichotomous scales relating to where they focus their attention, how they prefer to take in information, how they make decisions, and how they deal with the outer world. Based on an individual's preferences on these four scales, they are categorized into one of 16 distinct personality types that can provide insight into an individual's behaviors and how they can best operate and work with others.
