Hypothetical ECDI values for major historical events that shaped civilization's risk landscape
October 1962
13-day confrontation between the United States and the Soviet Union over Soviet ballistic missiles deployed in Cuba. Considered the closest the Cold War came to escalating into a full-scale nuclear war.
April 1986
Nuclear accident at the Chernobyl Nuclear Power Plant in Ukraine. The worst nuclear disaster in history, releasing massive amounts of radioactive material into the atmosphere.

These ECDI values are hypothetical reconstructions based on historical analysis and expert assessment. They represent what the ECDI might have indicated if it existed at the time of these events. The values are calculated by applying the current ECDI methodology (7-dimension risk assessment with LLM analysis) to historical contexts, considering the information and threat perceptions available at that time.
