This is the origin of "you can't con an honest man." I was a victim of a very weird kind of con once, and I'm not ashamed to admit that my ego played a huge role in getting me to fall for it. Con men play to the mark's ego because because it works!
(Luckily in my case I escaped with little loss, and didn't end up in an Argentine jail.)
