Respectfully, you chose the wrong hill to die on. Psychology has many squishy parts, but psychometry is basically the closest thing it has to a hard science.
The other comment adresses your NQ argument, but here's something I don't understand: "There's a very uncomfortable result about IQ tests that a generation of psychologists have tried to explain away"
This reeks of anti-intellectualism by the way ("can't trust the experts!"), but I am curious to know what you're referring to. It can't be the validity or reliability of IQ tests, surely? Both have been very solidly established for a long time.
