What It Measures

The Myers-Briggs Type Indicator (MBTI) identifies 16 distinct personality types based on four dichotomies that describe how people perceive the world and make decisions:

1. Energy Direction: Where you focus attention and get energy

   • Extraversion (E) - Outer world of people and activity
   • Introversion (I) - Inner world of thoughts and reflection

2. Information Gathering: How you take in information

   • Sensing (S) - Concrete facts and present realities
   • Intuition (N) - Patterns, meanings, and future possibilities

3. Decision Making: How you make decisions

   • Thinking (T) - Logic and objective analysis
   • Feeling (F) - Values and impact on people

4. Life Approach: How you deal with the outer world

   • Judging (J) - Structured, planned, organized
   • Perceiving (P) - Flexible, spontaneous, adaptable
