IQ tests are total bullshit right?

IDK, the Mensa shit has always rubbed me the same way stuff like Myers-Briggs does. I’m sure there’s maybe some applications for it? But mostly it seems like the kind of dick measuring contest that only prolifically stupid people concern themselves with. I feel like if you are a smart person it’s generally observable from the things you do and say. And the idea that intelligence is solely a genetic or unalterable condition, rather than being a combination of material and genetic factors seems to be the major takeaway for most people. I saw some twitter thread (low iq behavior) that exposed me to the existence of r/lowIQpeople and it’s just mind altering that some people allow this number to shape a big chunk of their self image. Also where the fuck do you get a reliable test done? How many people are paying $20 for some idiotic buzzfeed style quiz that tells you that your IQ is actually 140 and you’re just an untapped genius? My IQ is too low to answer these questions unfortunately
