Design a Feature to Combat Misinformation on a Social Platform

To combat health misinformation while respecting free speech, I propose a 'Context-Aware Nudge System' integrated into the Instagram and Facebook feed algorithms. First, we must define the scope: focus on content making definitive medical claims lacking peer-reviewed citations, rather than personal anecdotes. The core feature involves a two-stage intervention. Stage one is proactive: when a user attempts to share content flagged by our internal fact-checking partners or third-party health organizations as potentially misleading, a non-intrusive modal appears. Instead of blocking the share, it offers a 'Learn More' button linking to a neutral summary from authoritative sources like the WHO or CDC, framing it as 'Here's what experts say about this claim.' Stage two is reactive: if the content is widely shared but disputed, we attach a permanent, visible label below the post stating 'Disputed Claims' with a link to the evidence, without removing the original post. This preserves the creator's voice while providing critical context to viewers. We would measure success by tracking the reduction in shares of flagged content after seeing the nudge and monitoring engagement rates on the educational links. Crucially, we must A/B test these flows to ensure we aren't inadvertently suppressing legitimate health discussions or creating perception of bias, ensuring our approach aligns with Meta's commitment to open communication alongside community safety.
