No don't feel silly! Psychology is such a wide field, it is entirely possible I have missed opinions out there. I both love it and hate it LOL By all means pass over to me as many articles as you would like ^_

True environmental science is heavy on the biology from what I have been exposed to. I suppose that means you're more of a nature in the nurture vs nature debate ;) I tend to lean toward nurture, but I cannot deny nature's huge role. I really appreciate you jumping in to share your opinion. It's the only way we are exposed to new ideas in my opinion.

There is a lot to Myers-Briggs, starting with the Carl Jung base, but totally worth reading it. I think there's another psychologist as well that basically says you have both aspects to your personality. For example, introvert and extrovert, rational and creative. You are not one OR the other. Rather, you have both but one will be more dominant and you'll have moments of doing the opposite. I'm an introvert normally but sometimes I decide I must go out to be around people. Hope that helps and I look forward to more opinions from you. :D
