Facebook rolls out an interstitial screen that pops up when users try sharing COVID-19 content, showing the source and date created, adding much-needed friction
in this case, by adding friction & context via simple interstitials: https://twitter.com/... Oliver Darcy / @oliverdarcy : Facebook says it's rolling out “a global notification screen to give people more context about COVID-19 related links when they are about to share them. The notification will help people understand the recency & source of the content before they share it.” https://about.fb.com/... https://twitter.com/... Rev. Sam Harrelson / @samharrelson : Good move from Facebook. “The company is adding an interstitial that will make people stop and review context about links with Covid-19 information before they share it.” https://bigtechnology.substack.com/ ... Now do Q Anon and ancient alien pop ups! Alex Kantrowitz / @kantrowitz : News: Facebook is adding an interstitial to slow down Covid-19 post virality. It will appear before you share Covid-19 related links, except when they come from “credible health authorities.” A needed layer of friction as Covid misinformation spreads. https://bigtechnology.substack.com/ ...
Context & Ripple Effects
This interstitial is the latest step in a playbook Facebook has been building since its pop-up windows pointing vaccine searches to the CDC and WHO in 2019, then scaled up when the pandemic hit — free ads for health organizations and misinfo flagging announced by Zuckerberg in March 2020, followed by the temporary ban on face-mask ads and listings. What changes here is the intervention point: instead of acting on content or ads upstream, Facebook is inserting a pause at the moment of sharing itself.
The move also previews where the company went next — by December it was notifying users directly after they had liked, commented on, or shared COVID-19 misinformation, and in May 2021 it began testing a read-before-sharing prompt that followed Twitter's earlier version. Friction, not removal, is becoming the company's preferred tool.
First-order effects
- Users about to share a COVID-19 link now see an interstitial showing the source and creation date, which directly targets the recirculation of outdated or low-context posts rather than deleting them.
Second-order effects
- The success of pre-share friction pushes Facebook further down the same path: post-engagement misinformation notifications rolled out in December 2020, and a read-before-sharing prompt arrived in May 2021, mirroring Twitter's earlier version and signaling cross-platform convergence on nudge-style interventions.
Third-order effects
- If the pattern holds, mainstream content moderation shifts structurally from takedowns and bans toward interface-level friction — warnings, context screens, and read prompts embedded in the share flow — making the product design team, not just the policy team, the front line against misinformation.
The trend: Social platforms are replacing content removal with share-moment friction and context screens as their primary defense against viral misinformation.
