There are absolutely differences. Mass immigration to European nations is dangerous. And yes, it is replacement,(reply>), @Dedicated 1 You seem like the only epistemically rational person in this whole comment section. Wow,(reply>), @jesse shaver <br>In fact that is OBVIOUS if you look at the stats I showed you. 1984-2006 , Chinese 5-6year old IQ up by 5 POINTS during greatest industrial Revolution in history!,(reply>), @jesse shaver <br>I can see why you wrote your comment but you misunderstood.<br><br>Imagine a society, with 0 Universities.<br>The matching algorithm of smart people is random.<br><br>Now introduce 1 university.<br>The matching algorithm of smart people is more efficient.<br><br>Higher average IQ or even a more distributionally skewed one.<br><br>The hospital example is similar. <br><br>Either way, the point is, IQ is not intrinsic to a group.,(reply>), @Dedicated 1 i incorrectly assumed you were talking about nutrition/ availability of food. Anyways, I think you have some of that backwards.  Chicken and egg and such. It’s just that intelligent people were able to go to university in the past, and passed on their intelligence to their offspring. I don’t believe sending unintelligent individuals to university will increase their intelligence much.,(reply>), @jesse shaver <br>That’s with JUST talking about the concept of an ‘average’ IQ. <br><br>That’s WITHOUT even talking about limitations of IQ or even the philosophy of the idea! I.e. the consciousness/intelligence conflation.<br><br>That’s WITHOUT talking about the weakness of ‘race’ as a concept! Asian, black and white social construction or the statistics of haplogroups! (Causal channels of intelligence)<br><br>That’s WITHOUT talking about the Philosophy of society in terms of what we ‘should’ normatively do!
