The problem with most psychology is that the actual research never seems to filter down to the general populace. Would you believe me if I told you that...
* The types measured by the MBTI were originally proposed in Jung's 1921 book Psychological Types, and the first MBTI was constructed in 1962.
* In 1976, Eysenck proposed a new 3-factor model of personality, including Extraversion, Neuroticism, and Psychoticism (a factor of antisociality).
* In 1985, Costa and McCrae proposed a competing 3-factor model, using Extraversion, Neuroticism, and Openness (an analogue of MBTI "iNtuition").
Eventually it was realized that Openness need to be included alongside of Psychoticism. Then, as the state of knowledge continued to advance, researchers began to suspect that Psychoticism wasn't internally consistent and needed to be split into two factors.
* In 1990, Lewis Goldberg carried out a massive series of studies using hundreds of adjectives in the English language and asking people to rate themselves, and others, on each of these adjectives. Submitting the results to a mathematical process called Factor Analysis
, Goldberg found that five factors consistently appeared. Although the factors seemed somewhat different in character from study to study, they were recognizable as
This became the foundation for the "Big Five" model of personality traits; you can find this on Wikipedia.
Years later, as the methodology used to discover the Big Five was applied outside of English-speaking nations, it became clear that something was missing; other languages frequently returned a six-factor personality space. Looking back at Goldberg's studies, it was discovered that the apparently subtle differences in his results actually represented genuine differences in the factors being extracted.
* In 2004, Ashton, Lee, and Goldberg carried out a reanalysis of personality terms in English, supporting the existence of a sixth replicable factor of personality, which is now known as Honesty-Humility. Since then the six factor model has been replicated in about a dozen languages, including Korean, Italian, Dutch, and Filipino.
...So yes, it's new. It's just too bad that most people missed out on everything else
that was new in personality research for the past 50 years!
