Crystal’s Guide to Personality Types

The 16 Personalities framework is based on Carl Jung’s theory of psychological types, later developed by Isabel Briggs Myers and Katharine Cook Briggs. It categorizes people along four dimensions: Extraversion vs. Introversion (where you get energy), Sensing vs. Intuition (how you take in information), Thinking vs. Feeling (how you make decisions), and Judging vs. Perceiving (how you structure your life).

These four dimensions combine to create 16 distinct personality types, each identified by a four-letter code like INTJ or ESFP. The types are further grouped into four temperaments: Analysts, Diplomats, Sentinels, and Explorers, each sharing common values and approaches to life.

The Big Five (also called OCEAN) is the most scientifically validated personality model, backed by decades of research across cultures. Unlike other frameworks that put you into categories, the Big Five measures where you fall on five independent spectrums.

Each trait, Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism, exists on a continuum. You’re not simply “extraverted” or “introverted”; you have a specific level of extraversion that influences your behavior. This nuanced approach makes the Big Five particularly useful for research and detailed personality analysis.
