Hello ck2d: Thanks for sharing your thoughts. The brain is such a complex organ & there is still so much to learn about how it functions, or does not function, as the case may be. Personally, I would say that if the concept you have outlined is helpful to you in dealing with whatever mental health struggles you have, then run with it.
Personally, I pretty-much keep to myself at this late stage in my life. So I don't, at this point, have much experience with regard to how I view other people. However, I will say that I don't think I have much trouble with changing my view of other people. I'm pretty-much ready, willing, & able to scrap my good initial impression of people at a moment's notice, if I decide they weren't the person I thought them to be in the beginning. So perhaps that suggests that the dynamic you describe is not necessarily something that is common to everyone.
