Economists and finance experts have studied how ‘bad money drives out good’ and formulated Gresham’s law (Mokyr, 2003). The law states that the more expensive money tends to disappear from circulation because it is counterfeited, hoarded, or exported. One can propose a similar principle in the news business – real, verified, and socially relevant news tends to be replaced by fake, unverified, and often socially irrelevant news. This tends to happen not only in the American version of news production models (purportedly neutral and objective) but also in other more ideologically and politically oriented news production models.

后真理世界中的格雷沙姆定律和新闻

经济学家和金融专家研究了“不良金钱如何驱散良善”并制定了格雷沙姆定律（Mokyr，2003年）。法律规定，较昂贵的货币往往会因伪造，ho积或出口而从流通中消失。可以在新闻业务中提出类似的原则-真实的，经过验证的和与社会相关的新闻往往被假的，未经验证的，通常与社会无关的新闻所取代。这不仅会在美国版的新闻生产模型（据称是中立和客观的）中发生，而且还会在其他更加以思想和政治为导向的新闻生产模型中发生。
