The Neurological Basis of Con Games

Hugh Pickens writes "If we humans have such big brains, how can we get conned? Neuroeconomist Paul J. Zak has an interesting post on Psychology Today in which he recounts how he was the victim of a classic con called 'The Pigeon Drop' when he was a teenager and explains how con men take advantage of the Human Oxytocin Mediated Attachment System, called THOMAS, a powerful brain circuit that releases the neurochemical oxytocin when we are trusted and induces a desire to reciprocate the trust we have been shown. 'The key to a con is not that you trust the con man, but that he shows he trusts you. Con men ply their trade by appearing fragile or needing help, by seeming vulnerable,' writes Zak. 'Because of THOMAS, the human brain makes us feel good when we help others — this is the basis for attachment to family and friends and cooperation with strangers.' Zak's laboratory studies have shown that two percent of the college students he tested are 'unconditional nonreciprocators' who have learned how to simulate trustworthiness and would make good con men. Watch a video of Skeptics Society founder Michael Shermer running the classic pigeon drop on an unsuspecting victim and see if you wouldn't be taken in by a professional con man yourself."

      The con works by making you *trust* the con man. Very different from feeling good about helping. So if the conman makes you believe he trusts you, offers an easy opportunity to rip him off (buy a diamond at a massive discount), you may trust the premise of his offer (e.g. the diamond is real). If he makes you feel good about "helping" him in any substantial way (he needs money for a train ticket), it helps the more honest marks justify it to themselves (I'm making a profit, but I'm also helping the poor man).

But seeing localized activity in the brain and then drawing a conclusion about the mechanisms of behavior is the wrong way to interpret the data. I hate Psychology Today for pulling this crap all the time, activity in the brain is simply data to be interpreted, not a conclusion in itself. This is like when a segment of DNA is implicated in some sort of behavior or developmental trait, and we see the headlines "X gene discovered!!!". The question is simply too complex to answer with that kind of analysis.

    We cannot view the brain as a simple modular system, which merely needs a circuit diagram drawn to discover its mysteries. Functional specialization no doubt exists, but in an interconnected and complex way that resists simple explanations of "oh, this part of the brain lit up during this therefore this". Localization alone tells us little, it is only in complement with studies of neurotransmitter mechanisms, single cell recordings, computational theories, and numerous other techniques of brain exploration that any real answers are going to be found.

    Also, there are various kinds of smartness. A savvy con man can con a Nobel prize-awarded genius while failing to con an averagely-intelligent cop who simply has seen those kinds of tricks too often to fall for them.
