I've railed against these people before, and it's not that I think IQ is fake, or that it's not real, or that it doesn't correlate with anything.
A lot of this stuff seems to have started back in the 90s, when the cONtRoVeRSial research on racial differences in intelligence got started, but it seems like a lot of its supporters have forgotten that this 'ground-breaking' stuff is almost 30 years old at this point.
Yes, we get it, whites are smarter than browns, and upper-class whites are smarter than working-class whites. Shocking discoveries-- but fortunately we have the geniuses around to enlighten us on these issues.
Believe it or not, some people had also figured these truths out before the 90s, and using their own unique methods. However, autistic people will never understand empathy or intuition, so they always have to articulate and explain with reason what other people just do instinctively, which means it takes them forever to learn the basic facts that make up a normal person's instinctive, unconscious, knowledge or awareness of the world, such as X people do this, or Y people are like that, etc.
The problem lies not so much IQ as a metric itself, but rather with the copers or fetishists on social media. What they do is perform a sleight of hand, where their score suddenly becomes a great and wonderful achievement in and of itself, rather than just an indication of potential.
This is a mixture of 'everyone gets a trophy' and 'get out of jail free'.
They don't have to use their brains to be insightful, or learn anything about any subject, or acquire useful skills and regularly apply their knowledge in order to prove their intelligence. No, it's more like they try and make the fact that they have this high score automatically grant them genius status, and then they try to force everyone else to take them seriously because of that.
They don't understand that a bird in hand is worth two in the bush-- a person with medium IQ who is actually knowledgeable, and who is capable of using that knowledge for something good or productive is smarter in the real-world sense than a potential-but-not-actual genius who doesn't know anything and isn't capable of doing anything, or is even destined to fail (from sheer ignorance, lack of experience or training, etc).
The current bunch of tech-scammers are a good example of that kind of arrogant 'potential genius', accomplishing nothing (and doing that with other people's money) or even pulling scams, while also constantly patting themselves on the back for their cleverness.
This obsession usually overlaps with genetic coping and genetic copers, who also do the exact same thing. This is the 'muh ancestors' crowd / LARPers. What they do is say-- 'I'm X, and previous generations of my people did this or that'.
Meanwhile they've never done anything noteworthy, but they come from illustrious and impressive ancestors, which means their present-day actual mediocrity or retardedness is actually really superiority, and all without having to do anything in real life to back that up!
This is the typical syndrome of taking a tool and fetishizing it / obsessing over it so much that you forget that the tools is meant to help you do something or accomplish something rather than be an end in and of itself.
Superiority and intelligence are all demonstrated in the real world, through actual accomplishments or discoveries or impressive creations or conquests or whatever, not through unrealized possibilities or potentiality or 'ifs' and 'maybes' and so on.
And of course, if you're retarded and you accomplish and produce nothing or even fuck things up, then it's totally irrelevant who your ancestors are or what your IQ score is, since we have a much more direct and easy way to measure your worth (or worthlessness) than DNA or IQ.
The discourse on the Internet around these subjects is simply a way for these people to give themselves another trophy and then collectively celebrate their mediocrity, in one giant hive, rather than humble themselves and admit the truth.
