It seems to me that many nonbelievers have forgotten—or never knew—what it is like to suffer an unhappy collision with scientific rationality. We are open to good evidence and sound argument as a matter of principle, and are generally willing to follow wherever they may lead. Certain of us have made careers out of bemoaning the failure of religious people to adopt this same attitude.
However, I recently stumbled upon an example of secular intransigence that may give readers a sense of how religious people feel when their beliefs are criticized. It’s not a perfect analogy, as you will see, but the rigorous research I’ve conducted at dinner parties suggests that it is worth thinking about. We can call the phenomenon “the fireplace delusion.”
