This study investigates how partisan YouTube use can paint biased evaluations of one’s own as well as others’ knowledge. Understanding of these relationships is enriched by a fresh theoretical perspective via the Dunning–Kruger effect, suggesting that people, especially those who perform poorly, tend to overestimate their own competence. Using South Korea and the United States as two different contexts, we also attend to how cultures moderate these relationships. Findings based on two independent surveys in these countries shed light on the role of partisan YouTube use in shaping people’s hyperbolic self-evaluations and contrasted assessments of in- and out-group members. Furthermore, these trends are more pronounced among those with relatively a low level of actual knowledge. Finally, using partisan YouTube for news is strongly associated with group-based evaluations of knowledge in Korea, whereas it yields significant relationships only with self-evaluations of knowledge in the United States.

韩国和美国的党派 YouTube 对知识的使用和评估：通过邓宁-克鲁格效应获得的新视角

这项研究调查了 YouTube 的党派使用如何造成对自己和他人知识的偏见评估。邓宁-克鲁格效应带来的全新理论视角丰富了对这些关系的理解，这表明人们，尤其是那些表现不佳的人，往往会高估自己的能力。以韩国和美国作为两个不同的背景，我们还关注文化如何调节这些关系。基于在这些国家进行的两项独立调查的结果揭示了 YouTube 的党派使用在塑造人们夸张的自我评价以及对群体内和群体外成员的对比评估方面所发挥的作用。此外，这些趋势在实际知识水平相对较低的人中更为明显。最后，在韩国，使用党派 YouTube 播放新闻与基于群体的知识评估密切相关，而在美国，它仅与自我知识评估产生显着关系。
