Myers-Briggs Test Version II

Jung's theory of psychological type, as published in his 1921 book, was not tested through controlled, scientific studies.[25] Jung's methods primarily included introspection and anecdote, methods largely rejected by the modern field of psychology.[25]

Jung's type theory introduced a sequence of four cognitive functions (thinking, feeling, sensing, and intuition), each having one of two orientations (extraverted or introverted), for a total of eight functions. The Myers-Briggs theory is based on these eight functions, although with some differences in expression (see Differences from Jung above). However, neither the Myers-Briggs nor the Jungian models offer any scientific, experimental proof to support the existence, the sequence, the orientation, or the manifestation of these functions.[25]

Some researchers have interpreted the reliability of the test as being low. Studies have found that between 39% and 76% of those tested fall into different types upon retesting some weeks or years later.[9][33]

One study reports that the MBTI dichotomies exhibit good split-half reliability; however, the dichotomy scores are distributed in a bell curve, and the overall type allocations are less reliable. Also, test-retest reliability is sensitive to the time between tests. Within each dichotomy scale, as measured on Form G, about 83% of categorizations remain the same when individuals are retested within nine months, and around 75% when individuals are retested after nine months. About 50% of people tested within nine months remain the same overall type, and 36% remain the same type after more than nine months.[38] For Form M (the most current form of the MBTI instrument), these scores are higher (see MBTI Manual, p. 163, Table 8.6).

In one study, when people were asked to compare their preferred type to that assigned by the MBTI, only half of people picked the same profile.[39] Critics also argue that the MBTI lacks falsifiability, which can cause confirmation bias in the interpretation of results.

" I thought this test was too "general" and the choices too difficult. Often I was unsure or I didn't know if it really applied to me, so I chose a middle answer. I thought it would have helped if they'd given examples with many of these choices. Taking such tests can be fun, but I always find fault with them because I always find things that do not apply to me specifically, or are not clear enough, or I am not really sure of the terminology used. I like to answer as honestly as possible but if the choices are unclear, I have to guess too much. "
