AI总结:

本文构建区分文章偏见性与真实性的传播模型,分析其与读者信念的关系,并面向平台和用户提出降低假新闻传播率的干预建议。

摘要:

近年来,学者们对不可靠新闻(或称“假新闻”)给政治领域乃至整个民主制度带来的影响表示担忧。例如,人们普遍认为,假新闻在社交媒体上的传播影响了全国性选举的结果,包括2016年美国总统选举,以及2020年COVID-19疫情期间的局势。在个体层面上,是什么推动了假新闻的传播?哪些干预措施能够有效降低传播率?我们的模型将文章的偏见性与真实性区分开来,并考察这两个参数与读者自身信念之间的关系。利用该模型,我们为社交媒体平台和个体社交媒体用户提出政策建议,以减少不真实或高度偏见新闻的扩散。我们建议平台资助无偏见的真实新闻,将事实核查工作重点放在轻度至中度偏见的新闻上,推荐跨越政治光谱的好友建议,并向用户提供关于其信息流政治倾向的报告。我们建议个体社交媒体用户对与其政治偏见高度一致的新闻进行事实核查,并阅读持相反政治偏见的文章。

英文摘要:

In recent years, scholars have raised concerns on the effects that unreliable news, or "fake news," has on our political sphere, and our democracy as a whole. For example, the propagation of fake news on social media is widely believed to have influenced the outcome of national elections, including the 2016 U.S. Presidential Election, and the 2020 COVID-19 pandemic. What drives the propagation of fake news on an individual level, and which interventions could effectively reduce the propagation rate? Our model disentangles bias from truthfulness of an article and examines the relationship between these two parameters and a reader's own beliefs. Using the model, we create policy recommendations for both social media platforms and individual social media users to reduce the spread of untruthful or highly biased news. We recommend that platforms sponsor unbiased truthful news, focus fact-checking efforts on mild to moderately biased news, recommend friend suggestions across the political spectrum, and provide users with reports about the political alignment of their feed. We recommend that individual social media users fact check news that strongly aligns with their political bias and read articles of opposing political bias.
