<p>No, the true potential or innate abilities are the same. It is only that quite a few Asian kids start developing these abilities at a younger age and in a more intense way compared to many of their White and Jewish peers. It is only natural that this leads to overrepresentation at the earlier stages of the competititions. Later on White and Jewish kids catch up (which should not surprise anyone because their true potential has always been equal). It has nothing to do with losing or gaining innate abilties or getting dumber or smarter. Different cultures simply focus on different things at a different time.</p>
