I took an IQ test when I was 11 and got a score of 83. I retook it a few months ago (I'm 23 now) and got a score of 89. So I think anything is possible.,(reply>), @Lupi the Yorkie This is still an assumption though. If we're looking at this critically then I would ask you to find studies that show the average intelligence-level in southern US 'white-trash' communities, so localized studies are needed, and compare that with localized studies of groups in equivalent social-economic conditions in other, non-Caucasian, communities.,(reply>), Not to brag, but I got a 99 on that test.,(reply>), @Lupi the Yorkie never disputed that. To reduce intelligence to just this however is reductive, false, and lazy. To say this is the principle cause for intelligence differences is unproven. We know very very little about genes which control intelligence. I’m staying that you would need to give the appropriate amount of scientific scrutiny to such claims. Hell, we don’t even know how many genes control for intelligence or how they’re expressed.,(reply>), @shizz "you are out of your depth here and should learn more about basic biological principals"<br>Basic biological <b>principles</b> state that traits which are beneficial to survival will be naturally selected for in subsequent generations. <br>Intelligence is indisputably beneficial to survival in an environment with a climate that varies greatly during the year. This is really very basic evolutionary science.,(reply>), @shizz Mucho texto
