The Big Lie

The Big Lie fallacy rests on making an extreme statement and promoting it heavily until many people accept it. Once they accept it as a fact, one can build logical propositions on it, which they will also accept. Adolph Hitler observed that the masses of people will more easily fall victim to a great lie than to a small one. Perhaps most of us wouldn't have the nerve to tell an outlandish lie, and so we assume that the person telling an outlandish lie wouldn't either. We may unwittingly reason that "He wouldn't be saying that if there weren't some truth to it."
