Introduction
A surprisingly small design change can interrupt the spread of myths and misconceptions: asking people to pause before they repost. Read-before-sharing prompts are one of the simplest forms of platform friction. Instead of blocking content or judging whether a claim is true, they insert a brief moment of reflection between seeing a post and amplifying it.
The idea is based on a practical observation. Many false or misleading claims travel because sharing is nearly effortless. Users often repost headlines, screenshots or snippets without reading the underlying material, checking the source, or considering accuracy. By slowing that process at the exact moment a claim could reach a larger audience, platforms can reduce impulsive reposting and improve the quality of information that circulates. Research and platform experiments suggest that even lightweight prompts can meaningfully change behaviour without removing users’ ability to share.

Why myths benefit from one-click sharing
False claims often spread through speed rather than persuasion. A dramatic headline, emotional reaction or identity-affirming message can be shared in seconds. The user does not need to investigate the claim for it to travel.
Research into online misinformation repeatedly finds a gap between what people believe and what they share. Many users are not deliberately spreading falsehoods. Instead, social media environments encourage attention to humour, outrage, social approval and group identity, leaving accuracy in the background. When sharing becomes frictionless, that attention gap can help myths move faster than careful corrections.

Evidence suggests this is not a rare behaviour. A large study of news links shared on Facebook found that more than three-quarters of shared links were circulated without users clicking through to read the content first. In such conditions, headlines and social cues can matter more than the underlying article.

This is why the sharing moment attracts so much interest from researchers and platform designers. Once a claim has already spread widely, corrections face an uphill battle. A pause before reposting targets the earlier stage when amplification is still optional.
What read-before-sharing prompts change
The most widely known example came from Twitter’s “read before you retweet” experiment. Users attempting to repost an article they had not opened received a prompt asking whether they wanted to read it first. After testing the feature, Twitter reported that users opened articles 40% more often after seeing the prompt, and article-opening before retweeting increased by 33%. Some users chose not to repost after reading, which was considered a desirable outcome rather than a failure.

The significance of this intervention is not that it determined truth. The prompt did not label content as misinformation or remove posts. Instead, it altered the sequence of actions. Reading became slightly easier to choose than immediate amplification.
Researchers often describe this approach as a form of “friction”: a deliberate interruption of automatic behaviour. Studies examining misinformation sharing have found that asking people to pause and consider accuracy, explain why a headline might be true or false, or reflect briefly before sharing can reduce willingness to share false content while leaving sharing of accurate information largely unchanged. Misinformation Review [DOAJ]doaj.orgtrue or false indicated that they were less likely to share false information…
Attention rather than censorship
One common misconception is that these prompts work because they force users to accept a platform’s judgement. In reality, many successful interventions operate by redirecting attention rather than imposing a verdict.
A series of studies led by Gordon Pennycook and colleagues found that simple accuracy nudges improved the quality of information people said they would share. Even asking users to evaluate the accuracy of a single, unrelated headline could increase attention to accuracy in later sharing decisions. The proposed mechanism is straightforward: people often care about truthfulness but are distracted by other motivations when using social media.

From an implementation perspective, this matters because attention-based prompts can be deployed without requiring platforms to identify every false claim in advance. The intervention targets behaviour rather than content classification.
Why timing matters
The effectiveness of these prompts depends heavily on timing. A warning shown after a post has already gone viral may do little to prevent further spread. A prompt delivered at the exact moment of sharing influences a decision that has not yet been made.
Researchers studying online misinformation increasingly describe engagement as a sequence of choices: what to view, what to trust and what to share. Read-before-sharing prompts intervene at the final stage, where a user is deciding whether to amplify information to others. By targeting this decision point, platforms can affect diffusion without substantially altering what users are allowed to see.

Where protective friction becomes overreach
Although read-before-sharing prompts are generally considered one of the less intrusive interventions, they are not free of trade-offs.
A first concern is user fatigue. If prompts appear too frequently, people may learn to dismiss them automatically. The intervention then becomes background noise rather than a meaningful pause. Behavioural research on digital friction consistently suggests that effectiveness depends on careful targeting rather than constant interruption. [Nature]nature.commisinformation on social media: Experimental evidence for a scalable accuracy nudge intervention…. fake news” sharing on Twitter. Am…
A second concern is unequal burden. If prompts are applied selectively, users may perceive them as politically biased or ideologically motivated. Trust can erode if people believe the platform is steering behaviour in opaque ways rather than applying rules consistently.
There is also a practical limit to what friction alone can achieve. Some studies and modelling work suggest that simply making sharing harder may reduce overall posting activity without necessarily improving information quality. More promising results emerge when friction is combined with cues that help users recognise quality or accuracy. In other words, a pause works best when it encourages reflection rather than merely creating inconvenience.

Can a pause stop a false claim?
A pause cannot eliminate myths and misconceptions, and read-before-sharing prompts are not a substitute for media literacy, fact-checking or broader platform governance. Determined users can still repost misleading content, and some false claims spread through channels where prompts are absent.
However, the evidence suggests that many instances of misinformation sharing are surprisingly sensitive to small design changes. When platforms insert a brief moment for reading, reflection or accuracy consideration, users often behave differently. They open articles more frequently, pay greater attention to accuracy and become less likely to share questionable information impulsively.

For platform designers seeking to reduce the spread of false beliefs, this is the key lesson: myths often benefit from speed.
