Accuracy Prompts

Accuracy prompts are nudge interventions that shift users' attention to accuracy when evaluating or sharing news content. Typically implemented as simple reminders or questions asking users to consider accuracy before sharing (e.g., "How accurate is this claim?"), accuracy prompts aim to reduce misinformation sharing by making truth a salient decision criterion.

Key empirical findings

• Increases sharing discernment (ability to distinguish true from false news) by 2–10 percentage points across lab and field experiments
• Works across political spectrum for both Republicans/conservatives and Democrats/liberals, though with possible partisan moderation in some specifications
• Effect is driven by reduced false-news sharing rather than increased true-news sharing
• Works across diverse headlines, topics (politics, COVID-19), and platforms (MTurk, Lucid, Facebook, Twitter)
• Effect mechanism: shifts attention to accuracy during deliberation, not increased deliberation per se
• Effectiveness may be moderated by perceived headline accuracy; less effective for headlines people believe are true

• Bhardwaj et al. (2023) — Examining accuracy-prompt efficacy in combination with using colored borders to differentiate news and social content online — Tests accuracy prompts and visual borders in realistic mixed-content newsfeeds; finds accuracy prompts reduce false-news sharing 3.5–8.8%, and colored borders don't enhance this effect.
• Guay et al. (2023) — Examining Partisan Asymmetries in Fake News Sharing and the Efficacy of Accuracy Prompt Interventions — Tests whether three accuracy prompt variants work equally well for Republicans and Democrats in a balanced information environment; finds equal efficacy across parties

• Lin, Pennycook & Rand (2023) — Thinking more or thinking differently? — Demonstrates accuracy prompts shift attention to accuracy, not increase deliberation
• Pennycook & Rand (2020) — Fighting COVID-19 Misinformation on Social Media — Lab and field experiments showing accuracy nudges nearly triple truth discernment
• Pennycook et al. (2021) — Shifting attention to accuracy can reduce misinformation online — Nature paper demonstrating effects generalize across six lab experiments and a Twitter field experiment

Variants

Accuracy prompts take several forms, each with slightly different efficacy:

• Evaluation: Rate the accuracy of a single headline (most common; reliably effective)
• Importance: Emphasize importance of sharing only accurate news (effective in some studies)
• Social norms: Tell users that others think accuracy is important (mixed effects)
• Media literacy tips: Teach specific techniques for assessing credibility (some generalization)
• Multiple interventions: Stack several approaches (larger effects, but added complexity)
