Wow, this was sobering.
I still want to believe that this is something that is brought out by early experience. I would have liked to hear more about the researcher's claim that it's not. Just saying "some of them had wonderful families" isn't very convincing.
But it's creepy to consider the possibility that it's not. What if this is like autism? We used to believe that autism was caused by bad parenting, and it's not. Some people are really just born wired differently. What if psychopathy is like that?
