"Restraining world view" seems harsh IMHO. Sounds a little elitist to me. But affecting world-view is possibly correct.
I suspect the plasticity of the brain can overcome some of the things that the original O/S load affects but it seems to require either a big emotional event or real effort by people to undo the initial programming, like being dropped into a new country where you don't know the language but must learn it to survive. We figure it out.
It does beg the question however what are we missing, as a result of our initial programming, that we might want to download an update for. :)
