People in our experiment choose between two information sources with opposing biases in order to inform their guesses about a binary state. By varying the nature of the bias, we vary whether it is optimal to consult information sources biased towards or against prior beliefs. Even in our deliberately-abstract setting, there is strong evidence of confirmation-seeking and to a lesser extent contradiction-seeking heuristics leading people to choose information sources biased towards or against their priors. Analysis of post-experiment survey questions suggests that subjects follow these rules due to fundamental errors in reasoning about the relative informativeness of biased information sources.

人们如何在有偏见的信息源之间进行选择？来自实验室实验的证据

我们实验中的人们在两个具有相反偏见的信息源之间进行选择，以便告知他们对二元状态的猜测。通过改变偏见的性质，我们改变了咨询偏向或反对先前信念的信息源是否是最佳选择。即使在我们故意抽象的环境中，也有强有力的证据表明寻求确认和在较小程度上寻求矛盾的启发式方法导致人们选择偏向或反对他们先验的信息源。对实验后调查问题的分析表明，受试者之所以遵循这些规则，是因为在推理有偏见的信息源的相对信息量时存在根本错误。
