One Twin Was Hurt, the Other Was Not. Their Adult Mental Health Diverged

No, the study provides evidence that childhood abuse causes mental health problems in adulthood, which is much more specific than "bad".

> The critical discussion is how to reduce/prevent abuse

This is an entirely separate discussion.

This shouldn't be a controversial opinion, but it is. Corporal punishment is still legal [0], and is now being reintroduced in some schooling systems in the US [1]. "What doesn't kill you makes you stronger" and "pull yourself up by the bootstraps" are still common phrases in use, despite this research.

Particularly, mental illness research looking at genetic factors [2] [3], can cause people to downplay trauma-related mental illness, leading to things like "they were weak; other people can survive this", or my favorite "I went through that and I was fine, what's your problem" (N=1, but this last I heard _while someone was discussing their SA experience_).

We unfortunately need research like this and the linked below to provide common ground for the discussions needed to prevent abuse.
