alt Hacker NewsYeah, here [1] are the PISA outcomes. PISA is an international test that's generally the gold standard for comparison of educational outcomes on an international level. [1] Over the last testing year China was #2, the test prior #1. Singapore was #1 in the most recent period, and is around 75% ethnic Chinese.
Whether the differences are genetic or cultural is interesting but doesn't really matter. The reality is that they exist and are relatively immutable. For a very basic example, in China failing students fail. In American schools, failing students tend to be passed along. And such things are difficult to change, even if you could prove beyond any doubt that doing so would yield better outcomes for everybody.

The real question is how you 'do at life'. Some tests are a proxy but not all. And even when it is, you can 'teach the test' and get worse results at life even though the test itself is good. Too often we are not sure what is a good proxy.
That is the grain of salt all education comparisons need to be made with.
