Individuals who possess the virtue of epistemic autonomy rely upon themselves in their reasoning, judgment and decision making in virtuous ways. Philosophers working on intellectual virtue agree that if the pursuit of epistemic autonomy is not tempered by other virtues such as intellectual humility, it can lead to vices such as extreme intellectual individualism. Virtue theorists have made a number of empirical claims about the consequences of possessing this vice – e.g. that it will lead to significantly fewer epistemic goods (...) and a greater number of faulty beliefs. This paper reports the results of two pilot studies and initial results from a larger series of studies that attempt to shed light on some of the intellectual pitfalls of pursuing unrestricted epistemic autonomy. The studies provide empirical support for the philosophical claim that epistemic autonomy and intellectual humility are mutually supporting virtues by showing that epistemic autonomy without intellectual humility leads to increased belief in misinformation, conspiracy theories and pseudoscience and decreased trust in scientific experts. They also reveal important contours of the complex and often delicate relationship between the virtue of epistemic autonomy and its more vicious cousin, strong intellectual individualism. (shrink)
