I was wondering if there is a term when you choose to believe something even when you know it is likely untrue?
The concept I'm thinking of would differ from cognitive dissonance in that you're choosing a theory to believe, so there is no absolutely right answer. Or when someone has a pet theory that has little or no evidence for or against.
Examples I would give that might fall into this might be believing horoscopes/star signs, one religion over another.
"I have a pet theory, that honestly is likely false, but I choose to believe it, and almost actively would prevent proving it wrong." Is there a term to describe that belief, or the act of holding it?
