My results aren't guaranteed to reflect objective reality

reproducibility is not objective reality

as personality is subjective

a person can have 1 type, but answer differently

depending on various factors

not all of which can be accounted for

I took one and it says I am extraverted

which is true yet false

this problem comes up in medicine a lot

I see what you're saying

a lot of stuff is tested to be just great, very useful

but has no clinical significance once actually put into practice

partly that's just bad faith testing

correct would be:
Extremely open to new experience
Highly conscientious
Extremes of introversion and extraversion depending on the day
Not agreeable at all
High neuroticism

and a lot of stuff done in medicine does not have good ("A") evidence

5 disparate things that come together into nothing at all, I've always found

what five things

the ones @Deleted User 57835c2c just said

its his big 5

what do you mean by "come together into nothing at all"

that they're orthogonal?

you cannot derive anything from it, new knowledge, it doesn't tell you anything about the person beyond the sum of the parts tested

whereas an MBTI profile tells you a lot

you can predict their responses to specific scenarios based on that information

that's helpful

like even your skepticism for this stuff

fits with your type

yeah, but when you predict

I don't doubt that MBTI can make solid analyses of personality

you're just using the result itself

you're not getting a holistic picture out of it that tells you about how that person thinks

what they may value, and how

why not

sure sounds like it

I dont understand the question

*you're not getting a holistic picture out of it that tells you about how that person thinks*

you can tell they are introverted if they score high on introversion

yeah

isn't that a personality trait

you can tell they are neurotic if they score high on neuroticism

its a personality trait, sure
