• Totalitarian networks: All information passes through central hub

2. Historical Examples

• Three Mile Island: Rapid information flow, quick public awareness, lessons learned

Stalin’s Soviet Union

• Lysenkoism disaster in agriculture
• Pavel Rychagov case - truth-telling punished

• Stalin’s death delayed by fear of doctors

3. Trade-offs
