What's with all the personality typesi

I got curious because I've seen several people describing themselves or talking about those on their bios. You know... INTJ, INTP, etc. I was just confused how normal the topic was. I guess I'm the weird one for not being aware lol. Btw, I checked when some of you were taking the test on the last post wins, and I was ISTP. https://i.imgur.com/v4hY2ZG.png Post yours to see what's the majority here...or kill time. https://www.16personalities.com/free-personality-test

I guess I was out of the loop about the topic. http://i0.kym-cdn.com/photos/images/original/001/246/209/53e.png

Its (for) fun and I keep getting INTP or ISTP for the last few years Intuition and Sensing goes hand in hand for me PS. Theres more personality theories besides MBTI to confuse yourself more

Ayee! Another one, that's cool. Enki told me there were like 3 ISTP here in MO. It's 4 then. And it's not really the topic of personalities therories that confused me. It was more like, I was surprised about how for a lot of people is a popular way to describe themselves. Something like that, doesn't matter anyway.

@Whisp i see. well, it gets people connected for some reason i dont really know why or how either. i guess its more easier to have this summarized four letters as a tool to identify oneself and to get to know someone further on personal level (outside this four letter). i can only compare it as some kind of small talk but with psychology i think i was mind boggled and wondered/questioned the same as to why a few years back but just concluded it as something "useful" maybe to people and forgot about it. ofc, im not speaking for them and perhaps just speaking out of my ass
