I often wonder how many extremely religious people start having doubts at some point in their lives, but reject those doubts primarily because of a sense of loss aversion. In other words, they fall (more or less subconsciously) for the so-called sunk cost fallacy.
"I have spent so much time, effort and money on this, I have invested so much emotionally on this, that it would be unthinkable for me to stop now, after all these years." They might not think explicitly like that, but that kind of idea might be the driving force that casts aside doubts and keeps them practicing the religion.
Can this make people irredeemably religious, with no way out? Imagine if someone like Ray Comfort or Kent Hovind slowly but steadily started to "get" what skepticism, the scientific method and things like the theory of evolution are about, and understand at some level that they are making excuses for the Bible in order to defend it, and thus having serious doubts about their faith. Would they be able to accept that they have been preaching falsities and lying to people all these years? Could they come out and admit that they have been wrong and that they are now atheist rational skeptics? Or would the sunk cost fallacy prevent them from doing that, making them forcibly shove aside any such doubts and keep self-brainwashing with even stronger emphasis? Would they feel too ashamed to toss basically all their lives aside and start anew? Is their situation hopeless?
