Now, if you really want answers to some of your questions above, I could go on at some length trying to provide them. But given the rabidly irrational and vitriolic reactions we have seen expressed here by the local "disturbed commentators", it seems pretty clear that would be pointless and pretty unpleasant.

Perhaps, but I think it's time for you to declare - without insult to your apparent debating opponents - precisely what your view of IQ testing is.
This can be stated clearly and efficiently I'm sure.
Either these tests accurately measure this thing we call "intelligence" or they don't. Or, to state a middle position, they accurately measure intelligence but with caveats.
I toss these ideas out for you to play with and build upon - an outline of sorts.
Your move.
