The 16 Personality Types
Complete, honest guides to all sixteen types — the Analysts, Diplomats, Sentinels, and Explorers. Each guide covers careers, relationships, communication, conflict, stress, money, and growth, grounded in trait theory with clear limits on what a type can and cannot tell you. For career direction rather than personality style, see our guide to Holland codes and RIASEC. For a dimensional alternative to type labels, compare the Big Five personality traits and OCEAN scores.
