The debate around “fake news” has raised the question of whether liberals and conservatives differ, first, in their ability to discern true from false information, and second, in their tendency to give more credit to information that is ideologically congruent. Typical designs to measure these asymmetries select, often arbitrarily, a small set of news items as experimental stimuli without clear reference to a “population of information.” This pre-registered study takes an alternative approach by, first, conceptualizing estimands in relation to all political news. Second, to represent this target population, it uses a set of 80 randomly sampled items from a large collection of articles from Google News and three fact-checking sites. In a subsequent survey, a quota sample of US participants (n = 1,393) indicate whether they believe the news items to be true. Conservatives are less truth-discerning than liberals, but also less affected by the congruence of news.

真理与偏见，左派与右派：用现实的新闻供应检验意识形态的不对称性

围绕“假新闻”的争论引发了这样一个问题：自由派和保守派是否存在差异，首先是他们辨别真假信息的能力，其次是他们倾向于更多地相信意识形态上一致的信息。衡量这些不对称性的典型设计通常是任意选择一小组新闻项目作为实验刺激，而没有明确参考“信息群”。这项预先注册的研究采用了另一种方法，首先，概念化与所有政治新闻相关的估计值。其次，为了代表这一目标人群，它使用了从 Google 新闻和三个事实核查网站的大量文章中随机抽取的 80 个项目。在随后的一项调查中，美国参与者的配额样本（n = 1,393）表明他们是否相信新闻报道是真实的。保守派不像自由派那样善于辨别真相，但也较少受到新闻一致性的影响。
