ABSTRACT Opinion leaders play a significant role in public opinion formation by highlighting, defining and framing political issues for their circle of friends. Although we know opinion leaders are more likely to participate in politics, we are less sure about how they process mediated information and what motivate them to participate more actively than individuals who are less politically active. Data from a national representative survey in Colombia show not only that opinion leaders perceive more media bias and hostility, but also that the degree of their perceived media hostility is capable of motivating higher levels of political talk and participation.

意见领袖、感知到的媒体敌意和政治参与

摘要 意见领袖通过为他们的朋友圈突出、定义和构建政治问题，在舆论形成中发挥着重要作用。尽管我们知道意见领袖更有可能参与政治，但我们不太确定他们如何处理中介信息以及是什么促使他们比政治上不太活跃的人更积极地参与。哥伦比亚全国代表性调查的数据表明，意见领袖不仅感知到更多的媒体偏见和敌意，而且他们感知到的媒体敌意程度能够激发更高水平的政治谈话和参与。
