From a writer in The Guardian:
"I choose to believe Jackie. I lose nothing by doing so, even if I’m later proven wrong – but at least I will still be able to sleep at night for having stood by a young woman who may have been through an awful trauma."
Again, belief is here justified not on the basis of evidence, not as a matter of plausibility, but as an evaluation of cost. Not utilitarian social cost this time, just self cost: "I lose nothing by doing so."
Whether you know it or not, you pay a terrible cost.
Your tether to reality is lost.
