Simple truths
Which have taken me long to clarify
Undoubtedly some countries produce people who are more skilled than others.
Some this is due to institutions.
Some this is due to culture.
Obviously these things are related to each other.
It is clear is that population-level genetics is not a major driver of skill differences in the vast majority of fields.
Which is great, because while you can’t change your genes, you can opt into a new culture, or seek out new institutions under which to flourish.
And it also clear that the downsides of discriminating against people on the basis of genetics are so insidious, that it is worth having a strong cultural taboo against this kind of discrimination.

Good faith question, not intended as a trap:
Do you think people _should_ seek to opt into cultures where they can become maximally skilled? If you do believe that, is this an obligation to themselves, or to others?
