In an argument, when one refuses to make a simple search for evidence of their claim; however, they demand that the opposition does so. This creates a paradoxical position in which their belief is true and, when confronted with facts, either remains true or is discovered to be false.
In the event that it is discovered to be false, a second paradox often occurs in which the claim remains true by way of continuing to state it despite the evidence.
"Nobody has proven me wrong yet. Give me a source, I admit defeat. Don't, I stay right! Of course, I can obviously google for myself... but I have Schrödinger's evidence on my side!"
