标题： Social Media and Democracy

摘要： 我们研究具有政治议程的社会媒体平台影响投票结果的能力。 我们的基准是孔多塞陪审团定理，该定理指出，在多数投票下正确决策的可能性随着选民数量的增加而增加。 我们展示了社会媒体平台的信息操控如何推翻陪审团定理，从而削弱民主。 我们还表明，有时该平台只能通过提供与其偏好的结果相反方向的信息来做到这一点。 最后，我们将通过社交媒体操纵投票结果与通过传统媒体操纵进行比较。 显示英文摘要

摘要： We study the ability of a social media platform with a political agenda to influence voting outcomes. Our benchmark is Condorcet's jury theorem, which states that the likelihood of a correct decision under majority voting increases with the number of voters. We show how information manipulation by a social media platform can overturn the jury theorem, thereby undermining democracy. We also show that sometimes the platform can do so only by providing information that is biased in the opposite direction of its preferred outcome. Finally, we compare manipulation of voting outcomes through social media to manipulation through traditional media.
