If you are interested in 16 personality types developed by Isabel Briggs Myers, you may be interested in taking this test. Unlike free versions available elsewhere on the web, this test was professionally developed and scientifically validated. The test is not free but it isn’t expensive either and is probably well worth your time and effort.
The test takes about 20-30 minutes to complete and, at the end of the test, your four-letter type code will be revealed (e.g., INTJ or ESTP). You can use this four-letter type code to learn more about yourself by clicking on your type here (in addition, test authors also provide their own report):
