Gain: you’re conflating the outcome with the means of achieving that outcome. The IQ test does not attempt to measure social fairness. Its purpose is to reveal what is. What ought to be is a question for others.
It does not matter one jot if the kid in the Central African republic has a low IQ because of this, that and the other. The fact remains that he still has a low IQ, and that will hinder him for the rest of his life. The correct solution is not to pat the coons on the head and say, there, there, it’s not your fault you’re all backward, the white people will just fudge the measurements so you appear to be like us, even though you’re not really and never will be. [note to mods: I’m using the epithet to illustrate a particular viewpoint, not as a direct insult]
You don’t even seem to grasp how condescending your views are. When you know something is wrong, you can fix it. Or at least you might have half a chance. If we know that the CAR kid is dumb because of rampant malnutrition, people might be able to address that. When you sweep it all under the rug and pretend it’s normal, it NEVER gets fixed.
Incidentally, you appear not to have considered why certain countries might have a low-quality social environment, and poor or nonexistent education.
Higher than what? You don’t even seem to have a handle on the concept of ordinal rankings.
Remember first that IQ scores do not measure “intelligence”. Intelligence as a concept has never been satisfactorily defined. An IQ test is a multivariate measurement of one’s inherent cognitive capabilities; you might consider that a subset of what we colloquially call ‘intelligence’.
Now: visit any country with a low rating on the IQ table and you will be appalled by the general low level of cognitive ability. You will meet a large number of people unable to cope with (for example) simple if-then logic. While you might split hairs over whether Taiwanese people are more or less intelligent than, say, Americans or Japanese, it’s possible to experience first-hand that they are more intelligent that, say, Haitians. I realise you will instantly reach for you bag of excuses ‘explaining’ why this is so, but I think even you would have to acknowledge the reality of the difference.
