I could read about con men and tricksters all day.
"I could sell shit at an anti-scat party," he says, "you have to figure out someone's wants and needs and convince them what you have will fill their emotional void." A con man is essentially a salesman -- a remarkably good one -- who excels at making people feel special and understood. A con man validates the victim's desire to believe he has an edge on other people.
It requires avid study of psychology and body language. It's an amazing paradox--a con man has incredible emotional insight, but without the burden of compassion. He must take an intense interest in other people, complete strangers, and work to understand them, yet remain detached and uninvested. That the plan is to cheat these people and ultimately confirm many of their fears cannot be of concern.
The particular fellow profiled in that piece has also written a book called How to Cheat at Everything.
