研究发现，读者更有可能相信与自己政治倾向一致的新闻来源。我们要求：对政治结盟的新闻来源的更高的报道信任是由于感知到的机构可信度，还是仅仅反映了对结盟来源发布的政治主张的偏好？此外，受访者是否报告了他们对新闻的实际信念，还是选择表达他们的政治承诺？我们在美国进行了一项实验（N=400），使用新闻报道与新闻来源的随机关联以及经济激励来强有力地识别新闻信任的主要驱动因素并评估反应偏见。我们观察到消息来源对新闻评价的影响相对较弱，并发现反应差异主要是由于受访者的政治和新闻主张的一致性。我们还发现了表达性反应的重要证据，特别是在右倾的参与者中。
Studies have observed that readers are more likely to trust news sources that align with their own political leanings. We ask: is the higher reported trust in politically aligned news sources due to perceived institutional trustworthiness or does it merely reflect a preference for the political claims aligned sources publish? Furthermore, do respondents report their actual beliefs about news or do they choose to express their political commitments instead? We conducted a US-based experiment (N=400) using random association of news claims to news sources as well as financial incentives to robustly identify the main drivers of trust in news and to evaluate response bias. We observe a comparatively weak effect of source on news evaluation and find that response differences are largely due to the alignment of the respondents’ politics and the news claim. We also find significant evidence for expressive responding, in particular among right-leaning participants.
