Affected Groups

The article The implied truth effect: Attaching warnings to a subset of fake news headlines increases perceived accuracy of headlines without warnings (Pennycook et al. 2020) examines how the presence of warnings on online misinformation affects people's perception of accuracy and their willingness to share such information. The study conducted several experiments involving participants who were exposed to both true and false news stories, with some false stories accompanied by warnings and others without warnings. The findings of the study shed light on the groups that are particularly vulnerable to online misinformation (Pennycook et al. 2020). One group that is affected by online misinformation, as identified in the study, is older adults.(Pennycook et al. 2020) found that older adults were less likely than younger adults to detect false news stories and were more likely to perceive false stories as accurate, even when warnings were present. This suggests that older adults may be more susceptible to online misinformation due to challenges associated with cognitive processing and source credibility assessment. Another group affected by online misinformation, as identified in (Pennycook et al. 2020), is individuals with lower cognitive reflection. Cognitive reflection refers to the ability to critically evaluate information and overcome intuitive responses. (Pennycook et al. 2020) found that individuals with lower cognitive reflection were more likely to perceive false stories as accurate, especially when warnings were attached to those stories. This indicates that individuals with lower cognitive reflection may have difficulty discerning misinformation from accurate information, even when warnings are present. (Pennycook et al. 2020) highlighted that politically motivated individuals are also susceptible to online misinformation. The findings showed that individuals with stronger political preferences were more likely to perceive false stories that aligned with their political beliefs as accurate, regardless of whether warnings were present. This suggests that preexisting biases and motivated reasoning can influence people's perception of misinformation, leading them to believe false information that aligns with their political views(Pennycook et al. 2020).
