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.

How Does Your Mind Work? EQSQ Tests
Psychological tests developed by Professor Simon Baron-Cohen, Sally Wheelwright, and their team at the University of Cambridge, England, can give you insight into the way your brain functions. Specifically, you can discover
if you are more prone to empathize or systemize. Understanding how your mind works best naturally could enable you to make better study and career choices throughout life. This site also provides a brief but useful
explication of EQSQ Theory.
- Glenn Rowe's Male vs female brains
Simon Baron-Cohen's recent book The Essential Difference: Men, Women and the Extreme Male Brain proposes that "The female brain is predominantly
hard-wired for empathy. The male brain is predominantly hard-wired for understanding and building systems." The book contains a couple of tests that calculate your "empathy quotient"
and your "systemizing quotient". There is also a test that measures your "autism quotient", and a fascinating test that measures how good you are at discerning someone's mood from their eyes.
