... how that differs from denial is probably a very thin-to-nonexistent line, but even then the denial is a choice, isn't it?
I hope we can agree that disbelief and denial are two different things. Yes?
The former is a response to a lack of evidence ... while the latter is a response despite a preponderance of evidence.
At some point as a child, either you or someone you know got this inkling in the back of their mind that Santa Claus was a sham.
Or was it the case that the evidence was eventually revealed to be bogus or nonexistent?
But, despite the tingle, they kept right along with the myth of the Kringle. It was a choice. Conscious of it or not, a decision was made and whomever decided to choose Santa.
Hold on. The scenario you're describing
admittedly contains no actual belief in Santa ... only
the pretense of belief!
I agree 100% that people can opt
to behave in certain ways. That says nothing whatsoever about the nature of belief. What you're describing is a scenario where people no longer believe in Santa Claus, but opt
to pretend that they do.
I happen to think that your Hypothetical Santa Scenario might be an all-too-painfully-close-to-the-truth summary of religious belief in our era. No real belief at the core ... only
the pretense of belief. Habitual devotion. Call it what you will.
One might even go so far as to label it
institutionalized deceit.
And it isn't necessarily unique to our era. Skepticism® is only a few seconds younger than Unvarnished BS®.
I believe at every point in our lives, we make a decision of whether or not we will continue following the path of fables and myths that we've come to know since childhood. This includes everything from religion down to the trivial stuff that's rarely thought about.
And I shall maintain that belief is predicated
on evidence. In lieu of evidence of the existence of X, the rational response is to not believe in the existence of X.
1+1=2 only so much as I accept that it does. Belief has little to do with objective accuracy.
I think what you're describing is faith. Faith is typically the last arrow in the quiver after all the other excuses to believe on little or no evidence have been debunked. It has little to do with objective accuracy.
