I read The Greatest Hoax when it came out. Good book. What a creep Abagnale is. The book caught my eye becuase I remember seeing Abagnale give his lectures at Google, thinking, wow, this guy sure doesn't seem like a genius. We are all just gullible.
We also inherently expect most people play by similar rules as we do. For example, we anticipate other people have a conscience and feel bad when others suffer. Our interactions with others are partly based on this. However, for example a psychopath doesn’t experience those things, and therefore can do things that catch us off guard with ease.
In short, rogue agents can have a natural leg up when they are able to effectively emulate a behavior model- except here it’s social, instead of military.
