We used supervised machine-learning techniques to examine ideological asymmetries in online rumor transmission. Although liberals were more likely than conservatives to communicate in general about the 2013 Boston Marathon bombings (Study 1, = 26,422) and 2020 death of the sex trafficker Jeffrey Epstein (Study 2, = 141,670), conservatives were more likely to share rumors. Rumor-spreading decreased among liberals following official correction, but it among conservatives. Marathon rumors were spread twice as often by conservatives pre-correction, and nearly 10 times more often post-correction. Epstein rumors were spread twice as often by conservatives pre-correction, and nearly, eight times more often post-correction. With respect to ideologically congenial rumors, conservatives circulated the rumor that the Clinton family was involved in Epstein's death 18.6 times more often than liberals circulated the rumor that the Trump family was involved. More than 96% of all fake news domains were shared by conservative Twitter users.
我们使用有监督的机器学习技术来研究网络谣言传播中的意识形态不对称。尽管在 2013 年波士顿马拉松爆炸案（研究 1，N=26422）和 2020 年性交易者杰弗里·爱泼斯坦死亡案（研究 2，N=141670）中，自由派比保守派更有可能普遍传播信息，但保守派更有可能传播谣言。在官方纠正后，自由派传播谣言的情况有所减少，但保守派则不然。在未经修正的情况下，保守派传播马拉松谣言的频率是自由派的两倍，修正后的频率则是自由派的近 10 倍。在未经修正的情况下，保守派传播爱泼斯坦谣言的频率是自由派的两倍，修正后的频率则是自由派的近 8 倍。在涉及意识形态一致的谣言方面，保守派传播克林顿家族与爱泼斯坦之死有关的谣言的频率是自由派传播特朗普家族与爱泼斯坦之死有关的谣言的 18.6 倍。超过 96%的虚假新闻域名是由保守派推特用户分享的。
