Overview
Section titled “Overview”Toby Ord is a moral philosopher at Oxford University whose 2020 book “The Precipice” fundamentally shaped how the world thinks about existential risks. His quantitative estimates—10% chance of AI-caused extinction this century and 1-in-6 overall existential risk—became foundational anchors for AI risk discourse and resource allocation decisions.
Ord’s work bridges rigorous philosophical analysis with accessible public communication, making existential risk concepts mainstream while providing the intellectual foundation for the effective altruism movement. His framework for evaluating humanity’s long-term potential continues to influence policy, research priorities, and AI safety governance.

The Precipice: Landmark Contributions
Section titled “The Precipice: Landmark Contributions”Quantitative Risk Framework
Section titled “Quantitative Risk Framework”In “The Precipice,” Ord provided explicit probability estimates for various existential risks over the 21st century. These quantitative assessments became foundational anchors for the existential risk community, establishing a shared vocabulary for discussing comparative risk magnitudes. His estimates combined historical base rates, expert interviews, and philosophical reasoning about technological trajectory to arrive at what he explicitly frames as “rough and ready” estimates meant to guide prioritization rather than precise predictions.
| Risk Category | Estimate | Reasoning |
|---|---|---|
| Unaligned AI | 10% (1 in 10) | Ord identifies artificial intelligence as the single largest existential risk facing humanity this century. This estimate reflects the unprecedented potential for AI systems to exceed human capabilities across all domains, combined with fundamental difficulties in ensuring alignment between AI goals and human values. The probability is notably higher than other technological risks due to the rapid pace of AI development, the possibility of recursive self-improvement, and the one-shot nature of the control problem—once a sufficiently powerful misaligned AI is deployed, correction opportunities may be irreversibly lost. |
| Engineered Pandemics | 3.3% (1 in 30) | The second-largest risk stems from advances in biotechnology that could enable the deliberate creation of highly lethal and transmissible pathogens. Ord’s estimate accounts for the dual-use nature of biological research, the diffusion of bioengineering knowledge and tools, and the potential for both state and non-state actors to develop bioweapons. Unlike natural pandemics, engineered pathogens could be designed specifically for lethality, contagiousness, and resistance to countermeasures, making them substantially more dangerous than naturally occurring diseases. |
| Nuclear War | 0.1% (1 in 1,000) | While nuclear conflict could cause civilization collapse and hundreds of millions of deaths, Ord assesses the probability of actual human extinction from nuclear war as relatively low. Nuclear winter effects, while catastrophic for civilization, would likely leave some surviving human populations. The estimate reflects both the continued existence of massive nuclear arsenals and the various near-miss incidents throughout the Cold War and after, balanced against the stabilizing effects of deterrence theory and the reduced tensions following the Soviet Union’s collapse. |
| Natural Pandemics | 0.01% (1 in 10,000) | Based on historical precedent, naturally occurring pandemics pose minimal existential risk despite their potential for massive death tolls. No natural disease in human history has threatened complete extinction, and evolutionary pressures generally select against pathogens that kill all their hosts. While pandemics like COVID-19 demonstrate society’s vulnerability to natural disease emergence, the historical base rate for extinction-level natural pandemics is extremely low compared to anthropogenic risks. |
| Climate Change | 0.1% (1 in 1,000) | Ord’s climate change estimate reflects his assessment that while climate change represents a catastrophic risk to civilization with potential for hundreds of millions of deaths and massive ecological damage, the probability of it directly causing human extinction remains low. Humans are highly adaptable and geographically distributed, making complete extinction from climate effects unlikely even under worst-case warming scenarios. However, climate change could contribute to civilizational collapse or combine with other risks in dangerous ways. |
| Total All Risks | 16.7% (1 in 6) | Ord’s combined estimate aggregates all existential risks—both those listed explicitly and other potential threats—to arrive at approximately one-in-six odds that humanity faces an existential catastrophe this century. This aggregate figure accounts for potential interactions between risks and unknown threats not captured in individual categories. The estimate represents an unprecedented level of danger compared to any other century in human history, primarily driven by humanity’s rapidly advancing technological capabilities outpacing our wisdom and coordination mechanisms for managing those technologies safely. |
