Why Are “Others” So Polarized? Perceived Political Polarization and Media Use in 10 Countries
基于10国调查数据，研究发现网络新闻消费与公众对政党间分歧的感知极化稳定相关，而传统媒体使用的影响则因国而异，并通过实验验证了例证化解释。
This study tests the associations between news media use and perceived political polarization, conceptualized as citizens' beliefs about partisan divides among major political parties. Relying on representative surveys in Canada, Colombia, Greece, India, Italy, Japan, South Korea, Norway, the United Kingdom, and the United States, we test whether perceived polarization is related to the use of television news, newspaper, radio news, and online news media. Data show that online news consumption is systematically and consistently related to perceived polarization, but not to attitude polarization, understood as individual attitude extremity. In contrast, the relationships between traditional media use and perceived and attitude polarization is mostly country dependent. An explanation of these findings based on exemplification is proposed and tested in an experimental design.
