One of the aspects of human nature that enables cons to succeed is that persons see what they expect to see. (Actually, without any desire for personal gain, I have taken advantage of this aspect of human nature. It does indeed hold true.)
The Slactivist expands on this principle. A nugget:
Tea partiers tend to revere the U.S. Constitution in much the same way that many American evangelicals revere the Bible, which is to say they read it without comprehension, looking only for ammunition that can be used against their enemies. And since neither text was written for such a purpose, this so-called reverence is an exercise in illiteracy.
