In his autobiography Mein Kampf, or "My Struggle," Adolf Hitler wrote that people were more likely to believe a giant lie than a little one because they were willing to tell small lies in their own lives but "would be ashamed to resort to large-scale falsehoods." Since they could not conceive of telling "colossal untruths…they would not believe that others could have the impudence to distort the truth so infamously." He went on: "Even though the facts which prove this to be so may be brought clearly to their minds, they will still doubt and waver and will continue to think that there may be some other explanation."
The U.S. Office of Strategic Services had picked up on Hitler's manipulation of his followers when it described Hitler's psychological profile. It said, "His primary rules were: never allow the public to cool off; never admit a fault or wrong; never concede that there may be some good in your enemy; never leave room for alternatives; never accept blame; concentrate on one enemy at a time and blame him for everything that goes wrong; people will believe a big lie sooner than a little one; and if you repeat it frequently enough people will sooner or later believe it."
The MAGA movement is now based in the Big Lie. Its leaders refuse to admit that Trump lost the 2020 election. Trump's running mate, Ohio senator J.D. Vance, two days ago actually said Trump won, and as media figures more frequently ask the question of MAGA lawmakers, they continue to dodge it, as Arkansas senator Tom Cotton did today on NBC's Meet the Press, and as House speaker Mike Johnson did on ABC News's "This Week."
