description

Appeal To Ignorance is an attempt to win an argument by denying the null hypothesis; that is, to argue that if there is no evidence either for or against your proposition, that it can be accepted as true.

Note: this is sometimes argued to be a subtype of burden of proof fallacy.

examples

"Since the intermediates between archaeopteryx and aves are spotty, we can conclude that this is proof of God's hand in Creation."
