That study talks about teen brains. I’m talking about teen hormones. And that study fails to account for the facts that:

Mao’s rise was driven by youthful rebellion in China

Many Islamic suicide bombers are teenagers

The Amish have rumspringa

And yes some western teens are graffiti artists.

Teen rebellion cuts across cultures, that study just doesn’t show it because it is solely attempting to refute the univariate “brain” factor. I’m not talking about brains. I’m talking about hormones and risk tolerance. Teen rebellion cuts across cultures. And no single-variable “cross cultural study” can prove otherwise
