Absolute denial for atheists

This article is a deliberate meta-troll. To be successful I need your trolling cooperation. Now hear me out.

In The Strangest Thing An AI Could Tell You Eliezer talks about asognostics, who have one of their arm paralyzed, and what's most interesting are in absolute denial of this - in spite of overwhelming evidence that their arm is paralyzed they will just come with new and new rationalizations proving it's not.

Doesn't it sound like someone else we know? Yes, religious people! In spite of heaps of empirical evidence against existence of their particular flavour of the supernatural, internal inconsistency of their beliefs, and perfectly plausible alternative explanations being well known, something between 90% and 98% of humans believe in the supernatural world, and is in a state of absolute denial not too dissimilar to one of asognostics. Perhaps as many as billions of people in history have even been willing to die for their absurd beliefs.

We are mostly atheists here - we happen not to share this particular delusion. But please consider an outside view for a moment - how likely is it that unlike almost everyone else we don't have any other such delusions, for which we're in absolute denial of truth in spite of mounting heaps of evidence?

If the delusion is of the kind that all of us share it, we won't be able to find it without building an AI. We might have some of those - it's not too unlikely as we're a small and self-selected group.

What I want you to do is try to trigger absolute denial macro in your fellow rationalists! Is there anything that you consider proven beyond any possibility of doubt by both empirical evidence and pure logic, and yet saying it triggers automatic stream of rationalizations in other people? Yes, I pretty much ask you to troll, but it's a good kind of trolling, and I cannot think of any other way to find our delusions.

Human beings are all crazy.  And if you tap on our brains just a little, we get so crazy that even other humans notice.  Anosognosics are one of my favorite examples of this; people with right-hemisphere damage whose left arms become paralyzed, and who deny that their left arms are paralyzed, coming up with excuses whenever they're asked why they can't move their arms.

A truly wonderful form of brain damage - it disables your ability to notice or accept the brain damage.  If you're told outright that your arm is paralyzed, you'll deny it.  All the marvelous excuse-generating rationalization faculties of the brain will be mobilized to mask the damage from your own sight.  As Yvain summarized:

After a right-hemisphere stroke, she lost movement in her left arm but continuously denied it. When the doctor asked her to move her arm, and she observed it not moving, she claimed that it wasn't actually her arm, it was her daughter's. Why was her daughter's arm attached to her shoulder? The patient claimed her daughter had been there in the bed with her all week. Why was her wedding ring on her daughter's hand? The patient said her daughter had borrowed it. Where was the patient's arm? The patient "turned her head and searched in a bemused way over her left shoulder".

I find it disturbing that the brain has such a simple macro for absolute denial that it can be invoked as a side effect of paralysis.  That a single whack on the brain can both disable a left-side motor function, and disable our ability to recognize or accept the disability.  Other forms of brain damage also seem to both cause insanity and disallow recognition of that insanity - for example, when people insist that their friends have been replaced by exact duplicates after damage to face-recognizing areas.

And it really makes you wonder...

...what if we all have some form of brain damage in common, so that none of us notice some simple and obvious fact?  As blatant, perhaps, as our left arms being paralyzed?  Every time this fact intrudes into our universe, we come up with some ridiculous excuse to dismiss it - as ridiculous as "It's my daughter's arm" - only there's no sane doctor watching to pursue the argument any further.  (Would we all come up with the same excuse?)

If the "absolute denial macro" is that simple, and invoked that easily...
