摘要翻译：
我们研究了真实信息和虚假信息（谣言）在社交网络中的传播。当听到一个消息时，个人可能会相信它，不相信它，或者通过昂贵的验证来揭穿它。每当真相以稳定的状态存在时，谣言也是如此。网络社交只要增加了验证成本，就会加剧相对谣言的流行，而同源性的影响取决于确切的验证过程。我们的模型强调，打击谣言的成功政策增加了个人核实的动机。

英文摘要：
We study the diffusion of a true and a false message (the rumor) in a social network. Upon hearing a message, individuals may believe it, disbelieve it, or debunk it through costly verification. Whenever the truth survives in steady state, so does the rumor. Online social communication exacerbates relative rumor prevalence as long as it increases verification costs, while the impact of homophily depends on the exact verification process. Our model highlights that successful policies in the fight against rumors increase individuals' incentives to verify.
