The Illusory Truth Effect: How damaging will it get?

The Illusory Truth Effect can be defined as when repeated statements, regardless of how untrue they are, are perceived to be more truthful than newer statements, or those heard less frequently. In other words, most any fallacy, junk-science claim, fairy tale or misconception can be made to appear to be true if it is repeated frequently enough, especially if the opportunity to hear the contradictory facts is withheld.
