Undue Influence: Cons, Scams and Mind Control

by Patrick O’Reilly
and Phyllis Rosen

Internet scams, Ponzi schemes, real estate rip-offs, weird cults, fortune-telling cons—it’s hard to read the news without finding another example of a successful con artist at work. As the number of cons (and victims) grows, the term undue influence is gaining widespread use.

Undue Influence: Cons, Scams and Mind Control identifies the tools and techniques con artists use and the vulnerabilities they look for in victims. Most scammers, including some charismatic psychopaths, have the uncanny ability to adapt common techniques of manipulation and control to the personality of their victim, and given the right circumstances, everyone is susceptible. The information in this book might be your best resource the next time makes an offer so good you can’t turn it down.
