#fallacy
People won't stop believing in some things simply because they are false, especially when those beliefs are framed in a nice way or are beneficial.
> Many beliefs which collapse under scrutiny may nevertheless persist indefinitely when they are not scrutinized, and especially when skilled advocates are able to perpetuate those beliefs by forestalling scrutiny through appeals to emotions or interests. Some popular fallacies of today are centuries old and were refuted centuries ago, even if they are repackaged in up-to-date rhetoric to suit current times.
