在20世纪50年代Ward Edwards的开创性工作的推动下，经济学和其他社会科学所接受的理性预期模型所定义的决策理性假设在过去四十年中受到了严格的审查。更仔细的检查经常发现它缺乏描述的准确性。正如爱德华兹早在1954年就指出的那样，“心理学家很容易[证明]一个经济人……与一个真正的人非常不同”（第382页）。一般公众倾向于同意这种观点，并且对这种理性解释行为的失败并不感到惊讶。因此，小说家斯迈利（1995）让她的一个角色把关于这个主题的微观经济学讲座描述为“关于一个完全陌生的星球的欢乐故事，比扎罗星球，比扎罗超人的家园”（第141页）。
Triggered by the seminal work of Ward Edwards in the 1950s, the assumption of rationality in decision making as defined in the rational expectations model embraced by economics and other social sciences has come under scrutiny over the last fourty years. Closer inspection has frequently found it lacking in descriptive accuracy. As Edwards pointed out as early as 1954, “it is easy for a psychologist to [show] that an economic man… is very unlike a real man” (p. 382). The general public tends to agree and has not been surprised by the failure of this type of rationality to explain behavior. Thus the novelist Smiley (1995) has one of her characters describe a microeconomics lecture on the topic as “rollicking tales about an entirely alien planet, the Bizarro Planet, home of Bizarro Superman” (p. 141).
