Human beings have good reasons to think badly, politically. Read this essay which describes why and how to combat it on a personal level. I suspect this theory can be tested scientifically. If it pans out, perhaps this essay should be taught in our schools and even in our businesses, since office politics probably works the same way. Maybe Francis Porretto at The Palace Of Reason knows some classical scholar who elucidated the whole theory before the birth of Christ. If any of you know of one, it would be cool to find out.
