It’s perfectly reasonable to want to be right, to be right about everything, and especially right about what we believe, and especially right about what we just said. The problems of our world are many, but we are compelled by reality to solve them as best we can with the resources available. Time, attention, and money seem to be demanded every which way we turn and it seems impossible to attend to it all. One reasonable response is to get depressed and shrink away from all the demands that the world expects of us. Another reasonable response is to get angry and lash out at every insult that comes our way, and everything is an insult if you look carefully.
Being right becomes easier if we filter all these inputs through our natural filters built into us by our basic nature and our filters built on top of that by our experience. Thus, we can approach every new situation with two filters that limit what we must think about. If we squeeze those inputs by joining a social group, they will give us some more workable filters on the realities coming our way, so many inputs to our reality become simple to accept or to reject. Thus, there is less and less that we must attend to and think about when confronted with some person who says or does something we don’t understand immediately.
I just want to be right, and by limiting what I encounter and instantly categorizing it as good or bad, my world becomes easy to cope with, and I am always right. Those people are more than misinformed, they are choosing to accept a reality that is clearly wrong; thus, they are bad people and to be expelled from our local reality. We are right and they are wrong is easy to say and thus to believe. So, we double down on what we say and accept as friends others who have doubled down with us, and the world becomes even easier.
The only problem is that this often creates enemies and conflicts, and sometimes gets us hurt and sometimes gets us killed.
