Toward Ecosophy

This is a very odd question, but is there any occult factors in the way that the idea "We should never change our mind about anything because how convincing an argument sounds is unrelated to how true it is" seems to be taking off in the "rationalsphere"? It seems to me that it might be a desperate attempt to avoid admitting that their beliefs are obviously false, but it seems bizarre enough that I wonder if there's something else going on here...
