In policy debates and public relations campaigns, however, what you are more likely to hear is that a minimum wage must increase unemployment—because that’s what the model says. This conviction that the world must behave the way it does on the blackboard is what I call economism. This style of thinking is influential because it is clear and logical, reducing complex issues to simple, pseudo-mathematical axioms. But it is not simply an innocent mistake made by inattentive undergraduates. Economism is Economics 101 transformed into an ideology—an ideology that is particularly persuasive because it poses as a neutral means of understanding the world.Overextension of the scope of the model. The scope is determined by the assumptions, and the more restrictive the assumptions, the more limited the and the less realistic the model.
Economism is a logical fallacy used rhetorically to persuade through mathiness. It's not science but persuasion that amounts to sophistry. Intelligent economists know this. Those who don't realize it are unintelligent. So take you pick between liar and moron.
