"The Big Lie" refers to a propaganda technique where a falsehood is presented as a truth, often repeated so frequently that it becomes accepted by the public. This concept is rooted in the idea that people are more likely to believe a large, audacious lie than a small one, as it challenges their critical thinking. The term gained prominence in political discourse, particularly associated with Adolf Hitler's writings, where he suggested that the masses are more easily deceived by a significant falsehood. It has since been used to describe various political claims and misinformation campaigns throughout history.
