Free but fake speech: When giving primacy to the source decreases misinformation sharing on social media
研究发现，在Facebook上优先显示错误信息的来源（而非内容本身），能降低用户分享虚假新闻的意愿，因为这会减少对信息的信任并增加对欺骗意图的感知，且该效果仅在分享者与接收者关系较弱时成立。
Abstract Social media platforms are facing increasing tensions in balancing the desire to maintain freedom of expression with limiting the spread of fake news and misinformation. This study investigates whether giving primacy to the source of misinformation on Facebook influences users' sharing behaviour. Two experimental studies show that when fake news is presented in a source‐primacy format, users are less likely to share the post because of reduced trust in the message and increased perceptions of deceptive intent. Additionally, this effect persists only when the person sharing the fake news has a weak interpersonal relationship with the receiver. The study extends current understanding of how misinformation is shared and provides insights into how presentation formats can be used to limit the spread of fake news without restricting freedom of speech.
