Debates about post-truth need to take into account how news re-disseminates in a hybrid media system in which social networks and audience participation play a central role. Hence, there is a certain risk of reducing citizens’ exposure to politically adverse news content, creating ‘echo chambers’ of political affinity. This article presents the results of research conducted in agreement with 18 leading Spanish online news media, based on a survey (N = 6625) of their registered users. The results highlight that high levels of selective exposure that are a characteristic of offline media consumption are being moderated in the online realm. Although most of the respondents get news online from like-minded media, the figures related to those who also get news from media with a different media ideology should not be underestimated. As news consumption is becoming more ‘social,’ our research points out that Spanish citizens who are more active on social media sites are more likely to be exposed to news content from different ideological positions than those who are less active users. There is a weak association between the use of a particular social network site and gaining access to like- and non-like-minded news.

通过社交媒体偶然接触不喜欢主意的新闻：Echo-Chambers新闻摘要中的反对声音

关于真相问题的辩论需要考虑到新闻如何在混合媒体系统中重新传播，在该系统中社交网络和受众参与起着核心作用。因此，存在降低公民接触政治不利新闻内容的风险，从而形成具有政治亲和力的“回声室”。本文介绍了与18家西班牙领先的在线新闻媒体达成的研究结果，这些结果基于对他们的注册用户的调查（N = 6625）。结果表明，在线领域正在缓解作为离线媒体消费特征的高水平选择性曝光。尽管大多数受访者都是从志趣相投的媒体在线获取新闻，但与那些也从具有不同媒体意识形态的媒体获取新闻的人有关的数字也不应低估。随着新闻消费变得越来越“社会化”，我们的研究指出，在社交媒体网站上更活跃的西班牙公民比那些不那么活跃的用户更有可能接触来自不同意识形态立场的新闻内容。在使用特定的社交网站与获取具有相同和不具有相同想法的新闻之间存在弱关联。
