"Government, by its size, its momentum, and its authority, will not only perpetuate errors of doctrine or of policy, longer than they would otherwise retain acceptance, but it will multiply their effect on a geometric scale, as against the arithmetically cumulative effect of those errors if confined to individuals or smaller groups. The errors of tens of thousands of individuals, all thinking and probing in different directions and moved by different impulses, tend to cancel themselves out or to be softened by the attrition of doubt and disagreement. But let any one error become sanctified by government, and thus crystallized as truth, and little short of a revolution can discredit it or cause it to be discarded. "An easy illustration of this principle is the witchcraft terror in the early days of the colonial government of Massachusetts. If there had been no governmental power to give phantasmagoria the semblance of reality by official decree, the common sense of a majority of the citizens would have kept this manifestation of fanaticism from ever having such widespread support and cruel results. But once government had authoritatively said, 'This is truth,' then the hitherto doubting citizen was willing to join others like himself in accepting it as truth. And we have at least a dozen idiocies, equally repugnant to man's common sense and sound experience, being perpetuated by our government in Washington today." Robert Welch, The Blue Book
