Pilate saith unto him, What is truth? (John 18:38 KJV)
Since the Fall of man, man has resorted to the tools of violence and deception in order to rule man. While the use of arms for protection of justice can be justified, the use of deception is a symptom of the inherent human vileness. Religion, superstition, education, media, propaganda, disinformation, riots and a host of tools have been politically exploited to keep the masses under bait.
Hitler coined the term "Big Lie" for a propaganda technique that he himself used.
"...in the big lie there is always a certain force of credibility; because the broad masses of a nation are always more easily corrupted in the deeper strata of their emotional nature than consciously or voluntarily; and thus in the primitive simplicity of their minds they more readily fall victims to the big lie than the small lie, since they themselves often tell small lies in little matters but would be ashamed to resort to large-scale falsehoods. It would never come into their heads to fabricate colossal untruths, and they would not believe that others could have the impudence to distort the truth so infamously. 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. For the grossly impudent lie always leaves traces behind it, even after it has been nailed down, a fact which is known to all expert liars in this world and to all who conspire together in the art of lying." - Hitler, Mein Kampf
In brief, the principle states, as someone put it: "Tell a lie, speak it loudly, repeat it often, and the majority of the masses will believe you."
The masses lose out for the power of appeal. Sometimes it is the appeal of authority (someone who is well knowledgeable would know better, they think; but, fail to register that that same person could be deliberately lying or have been deceived himself). Sometimes, it is the appeal of the masses (the majority cannot be wrong, they think). Sometimes, it is the appeal of a famous personality or a celebrity (the appeal here would be more of a psychological nature, because one often tends to like what is liked by the person he/she adores).
In the olden times, lie was woven into religion through myths and legends that tried to establish the superiority of the royal family, the division of family lines, the inferiority of certain people, and taboos that protected power. In modern times, when science has destroyed many of the mythical grounds, there are other lying techniques ready at hand that deceive and delude men to support a political leader or party.
The Bible predicts that this is how the Antichrist, who will be an agent of the Devil, the Father of Lies, will come.
Even him, whose coming is after the working of Satan with all power and signs and lying wonders, And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. And for this cause God shall send them strong delusion, that they should believe a lie: That they all might be damned who believed not the truth, but had pleasure in unrighteousness. (2Th 2:9-12 KJV)
Modern Universities, Arts & Media, Politics, Markets, and Religion are all marching forward to the gate of deception that will soon happily welcome the Son of Perdition.
But, everyone who is of the truth hears the voice of the Lord; everyone who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God. (Joh 18:37; 3:21)
