They are boring, and I'm not even sure what the argument is. On the edges, I think there's a general agreement that low IQ is correlated with mental disability, and on the upper end high IQ is correlated with a certain type of cognition that makes you a good professional Mathematician or Physicist. I'm not sure what the big middle really says about anything. If I were to guess why this IQ debate keeps coming up is that it is a bit taboo now (which makes it very tantalizing in and of itself). There is also some gaslighting going on with certain segments claiming IQ is completely junk and has no genetic basis (even partially). This triggers the contrarians, who then themselves may overstate the science, prompting responses that may understate the science ... and so on.
