A cross-national examination of the effects of accuracy nudges and content veracity labels on belief in and sharing of misleading news
研究在英国、美国和香港测试了准确性提示和真实性标签能否帮助人们辨别真假新闻，发现两者结合能降低对假新闻的相信和分享意愿，但效果因人而异。
Abstract This study examined whether accuracy nudges and content veracity labels enhance people’s discernment in believing and sharing true versus false news. Participants in the United Kingdom, the United States, and Hong Kong were shown five true and five false social media posts in random order. Two true posts and two false posts were randomly assigned “True” and “False” labels, respectively. Multilevel regression models indicated that accuracy nudges and veracity labels had no direct effects on the perceived accuracy of posts or willingness to share them, though the interaction of the “False” label and accuracy nudge significantly reduced the perceived accuracy of and intention to share false news across the samples. Post hoc analyses further uncovered contingent effects based on individual differences, including partisan identity in the United States and conspiratorial thinking in the United Kingdom and Hong Kong. The findings demonstrate the efficacy of combined countermeasures in attenuating the effects of misinformation.
