Re: Educational level without brains
"The old saying goes that you can't con an honest man."
That's a great saying, honest men repeating that to each other makes them easier marks. One confidence book I read had a very different saying, that the easiest mark is one who believes he is perfectly honest. So, if you want to con a saint, you offer them a too-good-to-be-true opportunity to help the orphans, or whatever. Think of the children!
What makes people vulnerable to a con is lack of experience. Of course if you protect people too much, they don't acquire any experience. It reminds me of the old sysadmins who were against aliasing rm to something safer because making things safer just made users more careless.
I prefer to learn from other people's experience, by reading. But the way the brain works, or not works, sometimes there is no substitute for the real thing.
