Myers Briggs is posh astrology.

I think that's actually been proven at this point hasn't it?

[–] charlytune@mander.xyz 18 points 11 months ago (1 children)

That doesn't stop an absolute fuck ton of people believing in it. One of my friends is quite deeply into it, she's in FB groups about it, and decides what everyone's type is upon meeting them. According to her I only think it's nonsense because I've only done the free online tests, not the proper one. She wouldn't listen the other day when I tried to put her right about flouride in the water, either.

Sounds like the test itself isn't the problem but how it's used and how much people attach to the results, like with IQ tests. Neither that nor Myers-Briggs should be part of interviewing for a job either but apparently some US companies do it anyway.

No, the test itself is definitely the problem. Regardless of whether you believe a personality type test can be effective, the MBTI is particularly and provably ineffective in just about every measurable way:

It's not reliable. It has terrible test-retest reliability. If I'm X personality type, I shouldn't test as X type one time, and Y type the next, and Z 6 months laters.

It's not predictive. If a personality test accurately judges someone, it should mean you now know something about someone's behaviours, and can extrapolate that forwards and predict behavioural trends. MBTI does not.

It fundamentally doesn't match the data. MBTI relies upon the idea that people fall neatly into binary buckets (introverted vs extroverted, thinking vs feeling, etc). But the majority of people don't, and test with MBTI scores close to the line the test draws, following a normal distribution. So the line separating two sides of a bell curve ends up being arbitrary.

And finally, it's pushed very hard by the Myers-Briggs foundation, and not at all by independent scientific bodies. copying straight from wikipedia:

Most of the research supporting the MBTI's validity has been produced by the Center for Applications of Psychological Type, an organization run by the Myers–Briggs Foundation, and published in the center's own journal, the Journal of Psychological Type (JPT),

I risk sounding very "AKSHUALLYY" here, but online tests do a huge harm to the credibility of MBTI, no wonder it gets such a bad rep when the tests are so unreliable and people nevertheless base their entire personalities on it... Originally it's not supposed to be based on the binary choices of the 4 letters but the "cognitive functions" as defined by Carl Jung, which a lot of people will find to be just as much non-sense but with the right attitude I think they're a useful tool to learn about ourselves and others.

Yeah, anyone who thinks that there's exactly 16 types of person is using it like a horoscope, but that really isn't the point.

but the “cognitive functions” as defined by Carl Jung, which a lot of people will find to be just as much non-sense but with the right attitude I think they’re a useful tool to learn about ourselves and others.

Exactly, and that's what it helped me with. It's not a personality test about how you act outwardly (or which Pokémon you are or whatever), it's supposed to be about the inner workings.

But if you want an example of misuse: There's an MBT community on Reddit that is full of that sort of bullshit.

It shouldn't be taken as scientific truth but it can help you know yourself and others better, and it's an insult to compare it to astrology because at least it's not based on completely random things like the position of the planets when you were born. The issue is that most people only know MBTI as online tests, which are self-report and have extremely vague and stereotypical questions that can very easily be manipulated to get whatever result you want, with the worst offender being the most popular one, 16personalities, which isn't even an actual MBTI test but a BIg 5 one (which is not to say Big 5 is bad, but it's very misleading to map it to MBTI types). In reality to use MBTI somewhat effectively is going to take studying Carl Jung's work, how MBTI builds on that, lots of introspection, asking people about yourself, and lots of doubting and double checking your thinking. And very importantly you have to accept that in the end this all isn't real and just a way to conceptualize different aspects of our personalities and it's in no way predictive, you have to let go of stereotypes, anyone can act in any way, it's just about tendencies.
