McCrae, R. R., & Costa, P. T. (1989). Reinterpreting the Myers-Briggs Type Indicator from the perspective of the five-factor model of personality. Journal of Personality, 57(1), 17-40. What it reports: Used self-reports and peer ratings from 468 adults aged 19 to 93 to compare the Myers-Briggs Type Indicator with the five-factor model. It found no support for distinct types and found that the indicator measures four relatively independent dimensions that capture aspects of four major dimensions of normal personality.
Key ideas
The Five-Factor Model: The mainstream structural model of personality, which describes people on five continuous dimensions rather than sorting them into kinds: openness, conscientiousness, extraversion, agreeableness and neuroticism.
