Abstract

Across two studies with over 1,600 U.S. adults recruited online, we present evidence that people share false claims about COVID-19 partly because they simply fail to think sufficiently about whether or not content is accurate when deciding what to share. In Study 1, participants were far worse at discerning between true and false content when deciding what they would share on social media relative to when they are asked directly about accuracy. Furthermore, cognitive reflection and science knowledge were associated with stronger discernment. In Study 2, we found that a simple accuracy reminder at the beginning of the study – i.e., judging the accuracy of a non-COVID-19-related headline – more than doubled the level of truth discernment in participants’ sharing intentions. Our results, which mirror those found previously for political fake news, suggest that nudging people to think about accuracy is a simple way to improve choices about what to share on social media.

  • There is mixed research regarding whether corrections may actually increase belief in the original misinformation or in other misleading claims that fail to get corrected.

    “Moreover, there is mixed research regarding whether corrections may actually increase belief in the original misinformation 121,124-126 or in other misleading claims that fail to get corrected 127 .”

    From Using social and behavioural science to support COVID-19 pandemic response (2020) · cites this paper as [127]

    Citation 127 is attached to the suggestion that corrections may increase belief in other misleading claims that go uncorrected. The Statement of Relevance and Discussion describe an accuracy nudge that improved sharing decisions, not corrections or their effects on belief in uncorrected claims. Searches for correction backfire and uncorrected misinformation found no passage addressing that point; page numbers were unavailable in our copy. (LLM, conf=0.76)

  • There is a disconnect between perceptions of accuracy and sharing intentions: even when participants are good at distinguishing true and false headlines when asked to judge accuracy, this ability often does not translate to sharing.

    “Recent work has observed that there is a disconnect between perceptions of accuracy and sharing intentions: Even when participants are quite good at distinguishing between true and false headlines (if they are asked to judge accuracy), this ability to discern truth from falsehood often does not translate to sharing24–26.”
  • Prompting participants to think about accuracy reduces the disconnect between accuracy judgments and sharing intentions and thereby increases the quality of news shared.

    “Evidence for the role of inattention comes from experiments in which prompting participants to think about the concept of accuracy – for example, by asking them to evaluate the accuracy of a random headline at the beginning of the study – reduces the disconnect between accuracy judgments and sharing intentions, and thereby increases the quality of news shared24–26.”
  • There is a dissociation between accuracy judgments and sharing intentions observed in past work.

    “given the dissociation between accuracy judgments and sharing intentions observed in past work24–26”
  • The accuracy prompts are effective because they draw attention back to accuracy.

    “and that the accuracy prompts are effective because they draw attention back to accuracy24,26”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
