Module 1 / Lesson 2.9

Managing Existential and Global Catastrophic Risks

2 min read

Lesson guide

Learning:
- Familiarize yourself with the definitions of x-risk and GCR from Lesson 1.4.
- Recall the five categories of risk management from Lesson 1.3.
- Learn and master the material on this page below on how we manage x-risks differently than "normal" risks.
Reflection: As you read the material below, think about why standard risk management might fail for x-risks.

In Lesson 1.4, we defined Existential Risks (x-risks) as threats that could permanently curtail humanity's potential (e.g., extinction), and Global Catastrophic Risks (GCRs) as disasters with global scope but from which recovery might still be possible.

In Lesson 1.3, we outlined five standard strategies for managing risks: Insurance, Prevention, Saving, Information, and Recovery.

Which Strategies Work for Existential Risks?

Because x-risks have a "universal" scope and "terminal" severity, many of our standard tools break down. If an event ends civilization, there is no "after" during which we can file an insurance claim or rebuild.

Key Insight: Insurance, Saving, and Recovery generally cannot solve existential risks. We must rely almost entirely on Prevention and Information.

Strategy Category	For "Normal" Risks	For Existential Risks (X-Risks)
1. Insurance & Risk Transfer	Buy insurance against bike theft, risk is transferred to an insurer who pays if a loss occurs.	Not generally possible, no one is left to pay a claim after an existential event.
2. Prevention	Invest in a bike lock (reduce probability) or smoke alarm (reduce severity).	Potentially effective. Invest in "AI alignment" research (reduce probability) or building resilient agriculture for nuclear winter (reduce severity).
3. Saving	Emergency fund or rainy-day savings available for recovery after various losses.	Not possible for x-risks, no one left to deploy resources. (May help with GCRs, e.g., the Svalbard global seed vault).
4. Information & Early Warning	Auto safety ratings, medical screenings, campus weather alerts.	Potentially effective. Telescopes spotting asteroids, global epidemic surveillance, or researching novel risks.
5. Recovery	Disaster response, social safety nets, community rebuilding after a storm.	Not possible for x-risks, if humanity is extinct, there is no one left to recover.
