AGAIN: MBTI vs BIG5/6 vs MORAL FOUNDATIONS vs GENDER
In other words, the principle difference between MBTI and Big 5 are (a) the weight it gives to trait expression, and (b) the principle difference in value is that with 100 Questions we can test your IQ within a half a standard deviation, because all components scale evenly, but we cannot test the rest of your personality traits with so few questions because they do NOT scale evenly.
Moreover, MBTI is a WORKPLACE and social weighting of traits, while BIG5 is a THERAPEUTIC weighting of traits. These are differences in value rather than differences in measurement.
I was not the first person to make this distinction, but I have written extensively on the fact that while MBTI is imprecise, it is the maximum complexity of a model that individuals can work with in the workplace.
We can measure all sorts of trait expression, and even the big 5 FACTORS must be broken down into TRAITS in order to accommodate the difference in factor expression between the GENDERS.
In this sense MBTI is a better judge of the GENDER biases inherent in cognitive and emotional biases because its fairly obvious that the gender distributions are inverted.
Whereas this transparency was only visible in BIG5 after division from Factors into Trait Expressions – and that occurred fairly recently (post 2000), as psychology attempted to reform from a pseudoscience to a science when confronted with imaging, genetic, and pharmaceutical science.
