Steven Pinker: Social Media, Common Knowledge, and the Nature of Progress

The Challenge of Social Media Addiction

• ⚠️ Social media platforms like Facebook, X, and TikTok use algorithms designed for addiction by mining user data.
• 💡 A proposed solution is to allow users to disconnect comments from their posts, preventing pile-ons and spam.
• 🧠 There's a neurobiological difference between craving and pleasure, where people can crave things that don't actually provide enjoyment.
• 🎯 For teenagers, social media addiction can lead to unhappiness, but unilateral disengagement is difficult due to network effects and fear of missing out.

Common Knowledge in the Digital Age

• 🚀 Social media was initially hoped to be a common knowledge generator for collective action, as seen in events like the Arab Spring.
• 🔍 However, these platforms are not true common knowledge generators because algorithms personalize information delivery, making it unclear what others see.
• 🎭 The illusion of common knowledge is created through virality, where users can potentially generate widespread awareness.

The Illusion of Shared Understanding

• 📈 This illusion allows for issues like targeted political advertising, where different groups see different messages, hindering shared discourse.
• 💬 A vocal minority can exploit this to create the impression of widespread consensus, attempting to establish new norms.
• 💡 The term "common knowledge" is often a misnomer; "common belief" might be more accurate, as knowledge implies truth, which is often unverified online.

Why We Overlook Human Progress

• 📊 Despite significant improvements in human well-being, there are built-in biases towards gloom in news reporting.
• 🗞️ News tends to focus on fast-happening negative events, while gradual, positive changes (like escaping extreme poverty) are rarely reported.
• 🎯 Journalists often operate with a negativity bias, viewing "bad news as journalism and good news as advertising."

The Fragility of Progress

• ✅ Progress is an empirical fact evident in data on longevity, poverty reduction, and education, not just an optimistic viewpoint.
• 🌱 However, progress is not automatic; it results from human effort to solve problems and learn from mistakes.
• ⚠️ While many positive trends continue, there have been recent setbacks in democracy and war deaths, highlighting its unpredictable nature.
