It actually does not do that- each dimension which represents two opposite archetypes (e.g. introvert vs extrovert) is a continuum, and the output of the test isn’t actually a single category but a point on that line for each dimension. The full output is actually a 4 dimensional vector. Importantly- everyone has both traits, it is only telling you which you more consciously identify with. Many people will be near th…
I think you may have missed my point so I’ll give an example: Suppose you take a random sample of adult humans and sort them by height. What you’ll see is a bimodal distribution which reflects the fact that there are actually two distinct populations represented in the sample: men and women. The sexes can be considered types and you will get reasonably accurate results for predicting height from sex and vice versa. H…
Archetypes are fairly arbitrary concepts that isolate individual aspects among thousands that could potentially explain personality traits- they don’t claim to exist in real people.
It is critical to realize that in the dimensions on MBTI everyone is actually both, but some people strongly identify with one and reject or despise the part of themselves that represents the other.
