The size of the lie is a definite factor in causing it to be believed, because the vast masses of a nation are in the depths of their hearts more easily deceived than they are consciously and intentionally bad.
The primitive simplicity of their minds renders them more easy victims of a big lie than a small one, because they themselves often tell little lies but would be ashamed to tell big ones.
Such a form of lying would never enter their heads. They would never credit others with the possibility of such great impudence as the complete reversal of facts. Even explanations would long leave them in doubt and hesitation, and any trifling reason would dispose them to accept a thing as true.
Something therefore always remains and sticks from the most imprudent of lies, a fact which all bodies and individuals concerned in the art of lying in this world know only too well, and therefore they stop at nothing to achieve this end.
~ Adolph Hitler, Mein Kampf
