Frank Zappa once, maybe more than once, observed that "there is more stupidity than hydrogen in the universe, and it has a longer shelf life." The sheer ubiquity of stupidity guarantees that all of us will exhibit some of it from time to time, and I am certainly no exception: however, some people clearly abuse the privilege. They're not hard to find, either: any item at with the DUMBASS tag, or any winner (or runner-up) for a Darwin Award, can be safely assumed to be a person whose stupidity is assured.

Most of us, fortunately, aren't quite so bad off. But there are troubling signs out there, and if you exhibit any of these, perhaps you should be concerned:

  • If you think that you'll make any money from an email stock tout.

I used to track some of these things, and almost invariably the prices would sink shortly after the initial push. Of course, if you think you can get rich overnight by any means — but let's not go there.

  • If you think you'll save a lot of money by buying a hybrid vehicle.
