No it's not. Test creators keep 50 percent of items people get right and the smaller proportion of items people get right and wrong. This forces the curve and shows the presuppositions. You can make other groups more 'intelligent' with the right item selection. Do you deny that?

My claims 1) IQ tests don't test 'intelligence' 2) it can't be measured with what we have now due to the problems I discussed 3) they're poor because of how they're constructed 4) you can make other groups score higher by item selection
-
5) IQ tests form the normal curve due to how they're constructed with item selection 6) heritability of IQ increases due to, again, how the tests are constructed 7) therefore IQ tests are garbage and don't test 'intelligence'

If you own any statistics textbooks you can see that they verify my claim on IQ and construction.
