I am suggesting that this is a common normal (and unfortunate) human tendency and since I’m not extraordinary I assume I’m likely to suffer from this same weakness. I’m not promoting it as a good—but as a danger within each of us that we should try to compensate for.
In general, if we cultivate empathy, I think most of us can do better than some of our more unfortunate instincts.
On the other hand, I could be wrong and too pessimistic about some aspects of human nature.
But really, don’t most people believe “I’m right and the other guy is wrong”?!
