How do People Choose Between Biased Information Sources? Evidence from a Laboratory Experiment
通过实验室实验，研究人们在有对立偏见的信息源之间如何选择，发现人们倾向于选择支持自己先验信念的信息源（确认偏误），部分人也会选择相反的信息源，这源于对信息源相对信息量的推理错误。
Abstract 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.
