You seem to be suggesting that IQ tests simply don't work, not that their point isn't to compare people.

I'd even suggest the point of these tests is more than simply comparing people. IQ tests, at least how they are commonly used, are used to determine the one's worth as a human-being. I am not saying I personally agree with those views, but merely that such views are reflected in many modern societies and how people treat one another.

I think that would be a fair summary of my opinion of them, especially when related to the somewhat problematic view of "IQ" in popular culture.

As far as I can tell, their only real purpose in the UK is to try to convince "intelligent" people to give money to MENSA.
