It’s a fact that is generally suppressed by both narcissists themselves in the field (of which there are many: they think they have superior brains) and by conservative pro-lifers, who do not like to admit that adoption is so traumatic on infants that it is highly correlated to sociopathy. My mom was adopted and is a sociopath, and the worst of all I’ve known, and I trauma bonded to many. She was also named after her birth mother (the mark of the golden child) and then adopted and named after her adoptive parent, so she was twice golden childed and abandoned/abused in early development years. She went on to find her birth mother solely to get revenge: that is how much her adoption upset her all her life. She’s the saddest and most cruel woman I know.
