From Hashtag to Hate Crime: Twitter and Antiminority Sentiment
研究推特是否放大反少数群体情绪，以特朗普政治崛起为背景，发现推特使用增加与反穆斯林仇恨犯罪上升相关，特朗普的推文预测了后续的仇外推文、新闻提及和仇恨犯罪。
We study whether social media can amplify antiminority sentiment with a focus on Donald Trump’s political rise. Using an instrumental variable strategy based on Twitter’s early adopters at the South by Southwest festival in 2007, we find that higher Twitter use in a county is associated with a sizeable increase in anti-Muslim hate crimes after the 2016 presidential primaries. Trump’s tweets about Muslims predict increases in xenophobic tweets by his followers, cable news mentions of Muslims, and hate crimes on the following days. These results suggest that social media content can affect real-life out-comes.
