While the self esteem movement was plenty noxious and we are still living the consequences of it, a similar movement has enjoyed uncritical growth. That movement was the one that pushed reason. It comes in many guises. Critical thinking was one catch word. With children's programs we are seeing the word "hypothesis" and the scientific method thrown around quite a bit. The problem is not with reason itself.
It is ultimately a problem of hubris. One of the requirements for reason is knowledge. Society is coming around to accepting this. Society now has created a simple dichotomy. There are stupid people and intelligent people. The former can't reason, and the latter can. This would seem to solve a lot of problems except that it is unexceptional to hear someone refer to a person with a doctorate as an idiot. In other words, the people who agree with me are smart seems to be a convenient tautology regardless of the merits. While admittedly the rank tribalism so rampant today is an ill effect of this, I'm not sure it is worth dismissing as a bad thing altogether.
