An assertion that cannot be falsified by any conceivable evidence is nothing more than dogma

From Dan Garner's Future Babble, page 236.

An assertion that cannot be falsified by any conceivable evidence is nothing more than dogma. It can’t be debated. It can’t be proven or disproven. It’s just something people choose to believe or not for reasons that have nothing to do with fact and logic. And dogma is what predictions become when experts and their followers go to ridiculous lengths to dismiss clear evidence that they failed.
