This is not just an unfounded theory but a completely insane theory. Many (all?) of the countries ahead of the US in test scores also don’t “beat their kids” because that is absolutely fucking insane.

It’s such an American thing, to blame something on a lack of violence.

I'm not referring to the gap between the countries, I was focused on the historic development of the one population.

The old paradigm produced results(arguably?), but was "gutted". By this train of reasoning, this old, and still "current" teaching paradigm simply does not work without violent coercion is the point I was really trying to drive.
