I have only anecdotal evidence. I studied in one of the “top” middle schools in Moscow, Russia. Children (for example, myself) weren’t ostracised for being too nerdy or too curious in their studies, but also being relatively bad at studies wasn’t a factor that lowered someone’s status in that social group at all. I think there was almost no correlation between social status and classroom success. However, in ordinary schools, I know for sure that there is a negative correlation between social status and classroom success.

Maybe in the US, it’s very different.
