People believe repeated statements more compared to new statements - they show a truth by repetition effect. In three pre-registered experiments, we show that repetition may also increase perceptions that statements are used as fake news on social media, irrespective of the factual truth or falsehood of the statements (Experiment 1 & 2), but that repetition reduces perceptions of falsehood when the context of judgment is left unspecified (Experiment 3). On a theoretical level, the findings support an ecological account of repetition effects, as opposed to either a fluency-as-positivity or to an amplification account of these effects. On a practical level, they qualify the influence of repetition on the perception of fake news.
人们更相信重复的陈述而不是新的陈述——通过重复效应，他们展示了一个事实。在三个预先注册的实验中，我们表明，重复陈述也可能增加人们对这些陈述在社交媒体上被当作假新闻的看法，而不论这些陈述的事实真相如何（实验 1 和实验 2），但当判断的上下文未明确规定时，重复会降低对虚假陈述的看法（实验 3）。在理论层面上，这些发现支持了重复效应的生态解释，而不是流畅度作为积极性或这些效应的放大解释。在实践层面上，它们限定了重复对假新闻感知的影响。
