Cognitive Function Test
Based on the Work of Myers, Briggs, and Jung
This free personality test will allow you to obtain your scores on the eight Jungian functions as developed by Jung, Myers, Briggs, Moltzer, Schmid-Guisan, Wolff, von Franz, and van der Hoop. Though function tests have never been shown to have the same validity as traditional type tests, they are nevertheless able to provide a fuller, freer picture of the underlying mechanics of type.
Question 1 of 48
I can be fastidious about saving money and avoiding waste, even if I don't need to be.
IDR Labs Cognitive Function Test is the property of IDR Labs International.
Ours is one of the few free tests that is subjected to statistical controls and validation. Even so, please keep in mind that tests are merely indicators - a first peek at the system to get you started.
Myers-Briggs Type Indicator and MBTI are trademarks of the MBTI Trust, Inc., who publish the MBTI test. The Jung Type Indicator is the property of Psytech International.
Personality tests, whether they are professional or "official" tests like the MBTI test (the Myers-Briggs Type Indicator® MBTI), the Jung Type Indicator, or free online personality tests like this one, are indicators to help you find your personality type. No test ever devised can designate your personality type with complete accuracy or reliability and no MBTI or Jungian cognitive function test can replace familiarizing yourself with the works of Myers, Briggs, and Jung.
As the publishers of this online free personality test that allows you to discover your psychological type in the typology of Jung, Myers, and Briggs, we have endeavored to make this free online personality type test as reliable, accurate, and complete as possible.
Like the "official" tests such as the MBTI test (the Myers-Briggs Type Indicator® MBTI), the Jung Type Indicator, and other such professional, accurate instruments, our free online test is subjected to statistical controls and validation in order to make the results as accurate as possible.
We also draw on the psychology of personality types presented in C.G. Jung's Psychological Types as well the psychological insights into personality type tests as presented in the work of Isabel Briggs Myers, co-creator of the MBTI test (the Myers-Briggs Type Indicator® MBTI).
This test follows established theory. Our test follows the written theory of Jung, Myers, von Franz, and van der Hoop on the topic of personality type, rather than some slapdash approximation of Jung's theory.
Like the official Jungian personality tests like the MBTI test (the Myers-Briggs Type Indicator®), the Myers-Briggs®, or MBTI®, our free online test also draws on the works of J.H. van der Hoop and has endeavored to provide an accurate psychological assessment that stays as close to the official and authorized works of van der Hoop as possible.
The authors of this free online personality test are certified in the use of multiple different personality tests and have worked professionally with typology and personality testing. Prior to using our free online personality test, please note that while the four-letter type code provided is compatible with the type codes provided by the official MBTI test and the official MBTI® training material, this test should not be confused with official trademarked tests like the Myers-Briggs Type Indicator® or the Jung Type Indicator. The results of our free online personality test are provided "as-is", for free, and should not be construed as providing professional or certified advice of any kind. For more on our online personality test, please consult our Terms of Service.
