Sorry, not slippery enough. Awkward attempts at obfuscation cannot change the global and uniform underachievement of indigenous sub-Saharans evident through sociology, economics and history. When you have a valid example to show that this is not the case, then please do so. Indignation at a lack of political correctness isn't quite good enough.Who needs Rushton when things like sociology, economics and history suffice? Whether tt is simply a matter of facts conforming to the theory or the theory conforming to the facts, the results are invariable and equally obvious.However the o.p. is pushing the claptrap that this all stems from "Nature", not politics, not stereotypes, not differing religions, etc.
It's all due to Black people being Black, now that easily disproved and only simpleton's would subscribe to it.
Citing Rushton as a source is admitting that you really don't have a bridge to stand on.
This is the same guy that suggested smaller penises made you a more intelligent man...
If Rushton is not needed then why base the argument on his supposition???...try to follow along.
If things like sociology, economics and history were part of this argument, it would not progress pass one page.
