You have probably heard the saying attributed to circus magnate Phineas T. Barnum, "There's a sucker born every minute." Nearly all of us have been deceived at least a few times in our lives. Upon careful research, even Barnum's famous "quote" turns out to be a deception invented by one of his rivals. Usually, we are deceived about relatively minor matters, often because of our own carelessness. But it would be far more serious if we found we had been deceived about the major issues of life.
