Personality Tests
Online Tools

There are many "personality tests" online, some of them much better than most for introspective work. No such test is truly definitive, of course, however well crafted it might be. Those presented in the following list are among the most useful free (and some fee-based) instruments currently online.

• Thomson-Maidenbaum Personality Inventory
  The TMPI is an MBTI variant created by Lenore Thomson, author of Personality Type: An Owner's Manual (Boston: Shambhala, 1998), in which the test appears at pp.14-20, and Jungian analyst Aryeh Maidenbaum PhD. Thomson's book is an excellent resource, with detailed discussion of the dominant and secondary functions.
• Personality Patterns
  Personality Patterns is based on a novel algorithm that scores unique personality traits rather than rough "buckets" of personality types. The algorithm uses 45 different personality traits, each scored on a separate scale, resulting in extremely unique depictions of one’s personality, graphically visualized. The survey takes about 10 minutes to complete.
