Myers-Briggs Type Indicator

Model of personality types

The Myers–Briggs Type Indicator (MBTI) is an introspective self-report questionnaire indicating differing psychological preferences in how people perceive the world and make decisions. The test attempts to assign four categories: introversion or extraversion, sensing or intuition, thinking or feeling, judging or perceiving. One letter from each category is taken to produce a four-letter test result, like "INFJ" or "ENFP". Most of the research supporting the MBTI's validity has been produced by the Centre for Applications of Psychological Type, an organization run by the Myers-Briggs Foundation, and published in the Centre's own journal, the Journal of Psychological Type, raising questions of independence, bias, and conflict of interest. Independent sources have called the test "bullshit", "little more than a Chinese fortune cookie", "pretty much meaningless" and "the fad that won't die".Though the MBTI resembles some psychological theories, it is generally classified as pseudoscience, especially as pertains to its supposed predictive abilities. The indicator exhibits significant scientific (psychometric) deficiencies, notably including poor validity (i.e. not measuring what it purports to measure, not having predictive power or not having items that can be generalized), poor reliability (giving different results for the same person on different occasions), measuring categories that are not independent (some dichotomous traits have been noted to correlate with each other), and not being comprehensive (due to missing neuroticism). The four scales used in the MBTI have some correlation with four of the Big Five personality traits, which are a more commonly accepted framework.
