Sabine Hossenfelder - Community Notes are a Bad Idea
Meta's decision to replace human fact-checkers with community notes, similar to X (formerly Twitter), is criticized for potentially worsening misinformation issues. The argument is that fact-checking is inherently difficult, and relying on volunteers may not improve accuracy. Community notes often shift the burden of verification to other sources, which may not be reliable. Additionally, the sheer volume of content on platforms like Facebook, YouTube, and X makes comprehensive fact-checking impractical. The speaker suggests that misinformation often spreads from less popular posts, which community notes may not address. They propose that a bottom-up database of facts could help, but acknowledge the high cost and profitability of misinformation as barriers. Artificial intelligence could play a role if it becomes more reliable. The speaker concludes by advocating for scientific thinking as a way to combat misinformation.
Key Points:
- Meta is replacing human fact-checkers with community notes, similar to X's system.
- Fact-checking is challenging, and volunteers may not improve accuracy.
- Community notes often shift verification responsibility to unreliable sources.
- The volume of content on social media makes comprehensive fact-checking impractical.

5.3. Broader Context and Strategic Considerations
6. đź”— The Burden Shift in Fact-Checking
- Community Notes on Twitter often justify claims by linking to other websites, shifting the responsibility of fact-checking to these external sources rather than verifying the information directly.
- This reliance on external links does not effectively check facts but merely shows that others have made the same claims, potentially leading to misinformation.
- The approach underscores the continued relevance of mainstream media, as it highlights the limitations of crowd-sourced fact-checking features like Community Notes in ensuring information accuracy.
- For instance, while Community Notes are intended to democratize fact-checking by involving the community, they may inadvertently validate incorrect information if the linked sources are themselves unreliable.
- The process raises questions about the credibility of information on social media, emphasizing the need for enhanced verification mechanisms.
7. đź‘Ą Insufficient Community Participation
- Facebook users share about 4 billion items a day, indicating the vast amount of content requiring oversight, which is challenging given current participation levels.
- YouTube sees more than 3 million videos uploaded daily, underscoring the difficulty in managing content quality without sufficient community engagement.
- Platform X has about half a billion new posts daily, necessitating robust community participation for effective content moderation.
- Of the half a million people signed up for community notes on platform X, likely less than 10% actively contribute, highlighting a significant participation gap.
- The low active participation rate means most posts may never be fact-checked, risking content credibility and accuracy.
- To address this, platforms could implement incentives or streamlined tools to encourage more user involvement in moderation processes.
8. 🔍 Misinformation Under the Radar
- Community notes prioritize the most popular posts or topics contributors know or care about, potentially ignoring less popular misinformation.
- This focus on popularity rather than accuracy allows significant misinformation to remain unchecked, leading to potential widespread misinformation without proper oversight.
- The strategy of prioritizing popular content might miss critical but less visible misinformation, emphasizing the need for a more balanced approach that includes monitoring less prominent posts.
- A shift in focus towards accuracy over popularity could significantly enhance the detection and reduction of misinformation across platforms.
9. đź“Š Platform Size and Misinformation Spread
9.1. Impact of Platform Size on Misinformation
9.2. Potential Solutions to Combat Misinformation
10. 🌀 Community Notes and Misinformation Persistence
- Smaller platforms like X have limited post reach compared to larger platforms such as YouTube and Facebook, which have over ten times more users.
- The distribution of post popularity follows a power law across platforms, indicating misinformation thresholds scale with platform size.
- On major platforms like YouTube, misinformation may attract community notes once views reach between 50,000 to 100,000, highlighting the challenge of addressing misinformation.
- Misinformation campaigns often spread through fabricated stories from small accounts, as seen in previous COVID vaccine misinformation.
- When misinformation is flagged, believers may dismiss community notes as biased, similar to responses against fact-checkers.
11. đź› System Abuse and the Future of Community Notes
- Individuals are exploiting the system to advance personal agendas instead of focusing on correcting misinformation, leading to a misuse of community notes.
- Instances of abuse include downrating notes based on personal bias rather than factual errors, and fabricating misunderstandings to manipulate outcomes.
- There is a risk of organized groups manipulating the system for their benefit, indicating a need for enhanced oversight and improvement.
- Although community notes function effectively due to active contributors, there are emerging signs of systemic issues.
- Misinformation often remains unchallenged as individuals do not feel responsible for addressing it, shifting the burden to other platforms.

12. 🔍 The Complexity of Defining Reality
- Fact checking involves not just verifying information but grappling with the philosophical complexity of defining reality.
- The philosophical question of 'what is real' has been debated for millennia, with no definitive answers.
- Humans construct explanations of reality based on personal experiences, unable to confirm an independent existence of reality.
- Different philosophical theories, such as Plato's Allegory of the Cave or Descartes' skepticism, illustrate the challenges in perceiving reality.
- What is accepted as 'real' often aligns with what best explains individual experiences, highlighting the subjective nature of reality perception.
- Cultural and philosophical differences further complicate the understanding of reality, as various cultures may have differing beliefs and explanations.
13. 🧠Understanding Reality and Experience
- The most fundamental experience we recognize as real is our own thoughts, as encapsulated by Descartes' statement, 'I think therefore I am.'
- Direct sensory input is considered the next level of reality, but inferring reality beyond sensory input involves constructing a model of the world.
- Our acceptance of information that is removed from direct experience depends on how well it fits into our pre-existing world model.
- The process of determining the truth of secondhand information (e.g., a claim about Bigfoot) involves evaluating the credibility of the source and reconciling the claim with known laws (such as gravity), even though such evaluations are cognitively complex.
- To illustrate, consider how eyewitness accounts of phenomena like UFOs are often scrutinized against scientific understanding and personal biases.
14. 🌌 The Challenges of Knowledge Acquisition
- Knowledge acquisition is complex, requiring reasoning and information gathering to discern reality.
- Technological understanding significantly influences perceptions; for instance, misconceptions about cameras and modeling can lead to beliefs like flat earth theory.
