The Power of Citizen-Group Public-Policy Advertising
通过在线实验研究公民团体发布的公共政策广告对公众议题重要性感知、态度和知识的影响，发现广告能提升议题显著性和知识，但仅对无党派人士有说服效果。
Issue advertisements are advertisements designed to change public opinion about a social issue rather than advocate or oppose a candidate or ballot question or sell a product or service. What effect do these advertisements have on perceived importance of the advertised issue and attitudes and knowledge about the featured policy? Results from an online experiment studying the effect of online issue advertisements suggest that issue advertisements can increase the salience of and knowledge about an issue. Issue advertisements can also persuade about the merits of a policy but only among individuals without attachments to major political parties.
