Similarly, East Asians are protected against all kinds of environmental and mutational “attacks” that would normally destroy other people, intellectually, but this special blessing means that they will also tend to be under-represented among the most original human intellects. This solves one of the stronger challenges raised against the Unzian Asian Exception conjecture, asking why it was not East Asians who produced the greatest epochs of human intellectual achievements in history if it is true that their average IQs have consistently been stubbornly high for most of modern human history. It would be because the same canalization that protected them from low intelligence also “protected” them from producing the numbers of super-creative intellects that would be required for such revolutionary achievements in a concentrated period of time. They have a small creative smart fraction, in short.

This differential canalization theory is certainly more plausible than the existing models given by many hereditarians to explain why East Asians have a high average IQ. For example, the idea that East Asians were selected for intellectual novelty because they faced a very challenging environment has one obvious problem that somehow escapes the analyses of most hereditarians: if they were really selected for their ability to find novel solutions to problems, that should probably be the characteristic that distinguishes them the most even today. And yet the same hereditarians admit the conspicuous paucity of highly significant originators and innovators among East Asians, despite showing over-representation in high intellectual aptitude, sometimes very precociously so. East Asian women, who have the highest canalization coming from gender and race, are the most exemplary of this contrast. The shortage of such super-creative phenotypes can not be because they lack the numbers of people with the right genotype, but because the genotype is “buffered” from phenotypic expression by canalization.
