Economists think that matter is simple and that people can modeled similarly.

Por qué la Economía nunca será una ciencia dura y sobre las diferencias entre teorías y modelos (hechos y analogías)

Markets and prices are generated by human behavior. The greatest conceptual danger in modeling human behavior is idolatry, which is a kind of pragmamorphism, imagining that someone can write down a theory that encapsulates human behavior and relieves you of the difficulty of constant thinking. A model may be entrancing but no matter how hard you try, you will not be able to breath true life into it. To confuse a limited flawed model with a theory is to embrace a future disaster driven by the belief that humans obey mathematical rules.
