So adopted children match the IQ's of their adoptee families more closely than their biological parents when they are still living with their adoptee family. When they get out on their own, they end up reverting back to whatever their biologicals were, or more exactly they go off toward whatever their own DNA combo from their parents makes them. Which can be quite different of course from what their parents were.
I think that of course this can work both ways. The family you're stuck with can bring you down also and once you get out on your own you can slowly turn it around to some extent. Think this happened with me, though it took a while. My mom and stepfather were a huge negative for me and it took many years of being mostly away from them for me to rise up more or less to my potential.
So, when I look back at my childhood and who I was, how I related to other children, etc, it's all a bunch of shit. My father was extremely eccentric in his interactions thus I never learned how to interact with others. But worse, I lived in constant fear of him, his violent outbursts, his whole mindset of trying to beat me into being just like him, while having no ability to comprehend who I actually was.
In effect I have a lost childhood. A childhood full almost solely of negative memories. Which means I want to just forget it. But it's my foundation. And to the extent I forget my childhood, I wonder what that does to me. I find myself forgetting in general and wonder if it will lead to early althzeimers(sp).
