The Blind Spot in Human Nature

We cannot change human nature. The best we can do is to learn to recognize certain telltale signs of an attempt at deception and maintain our skepticism as we examine the evidence further. When people try to explain their ideas with so much exaggerated energy, or defend themselves with an intense level of denial, that is precisely when you should raise your antennae. We tend to take extra conviction for truth. This propensity is what deceivers and manipulators thrive on.
