Not really. Thousands (tends/hundreds of thousands?) of years of human society isn't going to just evaporate from a couple studies, even if they're incontrovertible.

Do you understand the post hoc fallacy?

I am not arguing that corporal punishment is effective because society has progressed. I'm saying that people are inflexible and even irrefutable science is unlikely to cause an immediate societal shift.

So your argument is that humans are feral? I don't think that's supported by the evidence either.

His argument is that culture is slow to change.

How in the world did you get "feral" from anything I'm saying?
