Minor point - prior knowledge is 'hot reading' or 'warm reading' when used with cold reading techniques.
Cold reading is trying to get info and hits with no knowledge about the subject other than what they give away during the reading.
Apologies if it has been mentioned in the billion posts before this.
Since we don't have a word for "things we have learned beforehand but don't recall learning or even realize that our 'impression' is based upon this knowledge" I chose to use the term cold reading and define how I was using it.
Like with vasectomy guy. It wouldn't surprise me at all to learn that VFF heard directly from VG or friends of VG that he had a vasectomy. Forgetting about it wouldn't surprise me either. And when attempting to "read" the guy it wouldn't surprise me that this led to an "impression" that VG had a little snip-snip done.
It would not surprise me that an imaginative person would visualize this in her mind. It wouldn't surprise me either to hear that person speak of the procedure in the singular not realizing that there would be two snip-snips, not one.
What does surprise me is that a rational person would dismiss such a simple explanation and instead walk around the mall trying to see if she could "sense" vasectomies in strangers.
It also surprises me that a rational person after failing to see vasectomies in anyone else despite there being a 1:6 prevalence in men over 35, would continue to believe that she really did see a vasectomy that one time.
It would NOT surprise me to hear that an irrational and/or delusional person would behave that way.
