Asians appear to be excellent learners, not inventors. It could be Asians come from a race of people which learned from Aryans in the past. Why they have higher IQ in average is a moot point. In my opinion I thinks is because of the Cultural Marxism introduced in Western academia at the begin of the 20th century to dumb down Aryans and restrict their intelligence. So Aryans in average have a slightly low IQ than Asians. However, as I said, it just an opinion. It could be that Asians are just really more efficient to use their intelligence than Aryans. After all, Aryans are not superior in everything. Negroes from Africa are far superior in some physical activities than Aryans.
