both delusional and a con man.
Not saying who I was talking about (IH,Rossi, someone else, me) , yesterday I had a talk with a "serious guy" interested in this domain, and he told me he had experienced similar profiles of "liar who believes his lies"... He told me they were "the worst of all".
It is hard for me to understand this profile.
- I understand the liar which lie and defraud consciously by selling fake unicorn manure from a hidden donkey... it seems (at least short term&risky) rational. Maddof seems of that kind, thinking he was smart enough to escape troubles forever.
- I understand the delusional guy who sincerely believes he have a pink invisible unicorn in his garden. The kind who get ruined but never cheat. Some crazy inventors and scientists are of that kind.
- There is even rational delusion as described by groupthink theory of motivated reasoning by Benabou (Patterns of Denial), where people avoid facing their failure, supporting each-others delusion, punishing doubters, following the boss delusion because nobody can escape (think the employees/contractants in that affair).
- But it seems there is a strange kind of people, who can sincerely believe in their lies, and consciously defraud... like the guy who consciously sell his donkey manure, but believes in unicorns.
Is there scientific resources, literature about that?
I've heard of "clivage" theory, but it is psychoanalysis...
Benabou's "Patterns of Denial" describes case like Enron CEO who both committed clear fraud to hide their failure but since the beginning and forever believed in their superiority to "make it works"...
