Previous work has shown that false information affects decision-making even after being corrected, a phenomenon known as "continued influence effects" (CIEs). Using mock social media posts about fictional political candidates, we observe robust within-participant CIEs: candidates targeted by corrected accusations are rated more poorly than candidates not targeted by allegations. These effects occur both immediately and after as much as a 2-day delay. We further demonstrate that vulnerability to CIEs in a political context varies systematically between individuals. We found that certain groups are more susceptible to CIEs on immediate candidate ratings (i) those who rely more on intuitive feelings, (ii) those with lower digital literacy knowledge, and (iii) younger individuals. These individuals' judgments appear to be relatively more influenced by the refuted accusations and/or less influenced by the factual refutations. Interestingly, political orientation did not affect CIEs, despite its influence on explicitly identifying misinformation. Moreover, people recalled accusation stimuli better than refutations at a delay, suggesting that emotions may drive the prioritized processing of accusations. Our results indicate that analytic thinking could be protective when people judge political candidates targeted by refuted false information.
先前的研究表明,错误信息即使在被纠正后仍会影响决策,这种现象被称为“持续影响效应”(CIEs)。通过使用关于虚构政治候选人的模拟社交媒体帖子,我们观察到了参与者内部强大的持续影响效应:被纠正指控针对的候选人比未被指控针对的候选人评分更低。这些效应在即时以及长达两天的延迟后都会出现。我们进一步证明,在政治背景下,个体对持续影响效应的易感性存在系统性差异。我们发现,某些群体在即时候选人评分上更容易受到持续影响效应的影响:(i)那些更依赖直觉感受的人,(ii)数字素养知识较低的人,以及(iii)年轻人。这些人的判断似乎相对更容易受到被驳斥指控的影响,和/或相对更不容易受到事实性驳斥的影响。有趣的是,政治倾向尽管会影响对错误信息的明确识别,但并不影响持续影响效应。此外,人们在延迟后对指控刺激的回忆比对驳斥的回忆更好,这表明情绪可能驱动了对指控的优先处理。我们的结果表明,当人们评判被驳斥的错误信息所针对的政治候选人时,分析性思维可能具有保护作用。
