Somewhat true but at some point, some people look around and realize even though something is at that point part of their psyche, they come to the realization that they've been had. I am aware that some people won't believe their eyes despite seeing evidence right in front of them, but a few aren't that foolish.

As that old Lincoln saying goes, you can fool some people all the time, all people some of the time, but you can't fool all people all the time.
