This sounds complicated.... I'm not sure I know what you mean.
If you mean what I think you mean, then I think you have a point. It seems like people are often starting with the pattern, filling it in with their own experiences, and using their own experiences a way of interpreting things back to the pattern. Which is the wrong way, most likely. You shouldn't necessarily filter your experiences or your perceptions to fit them into a pattern. I think, rather, you should keep your perceptions and experiences intact, and only use the pattern where it matches them to express them, and admit the places where the pattern and the experiences don't completely match.
It can be annoying when people start throwing out all the rationalizations for why a person could be a particular type, and getting mad at you if you question it or say it's unlikely, everyone else wanting to just jump on board and agree with the idea. It happens a lot actually... people throw out an idea, and everyone else just builds it up and says how great it is, adds some of their own interpretation and extension to it. Then if someone else comes along and pokes holes in it, everyone gets angry and defensive, at least dismissive, and often rationalize that you don't have a mature understanding, overanalyze, or are closed-minded.
Does that make sense?
