You posted some great links and I think I'm gonna have to take some time to read over them all. I'm leaning a little bit back towards 7 now, because of some of that stuff, and also because, introspection is *hard* and I'm a little alarmed by how much of it I'm having to do just in order to figure out that yeah, I don't like it that much. :V
I'm mostly curious what would explain the fact that, as a kid, I basically just holed up with a book all the time and didn't talk to anyone. But I remember thinking at one point that I was mostly doing that to avoid dealing with the ever present stress. From what I think I understand that's a pretty 7ish response?
