P(doom) Calculator

What's your personal probability estimate of catastrophic AI outcomes? Calibrate your existential risk view with structured thinking.

P(doom) calculator — AI existential risk probability estimator

This is an educational and exploratory tool. These estimates are deeply uncertain. Experts range from <1% to >50% P(doom). Use this to structure your thinking, not as a definitive answer.

Expert P(doom) Estimates

Why estimates vary so much: Researchers use different definitions. Some estimate extinction, others civilisational collapse or permanent disempowerment. Some give conditional probabilities (given AGI by 2100), others unconditional. Timeframes range from 30 years to never specified. These are subjective probability estimates, not scientific measurements.

Color coding: red >20%, yellow 1–20%, green <1%.

Estimates reflect the researcher's publicly stated view at the time of the source. P(doom) is not a standardised metric — definitions of 'doom', timeframes, and conditions vary by researcher.

The survey median (~5%) is substantially lower than the median of public expert statements (~20%). This gap reflects selection bias: researchers who make public statements about P(doom) are not a random sample of all AI researchers.

// What Is a Doom Calculator?

A doom calculator estimates the probability of catastrophic outcomes from advanced AI systems. In AI safety research, this probability is called P(doom) — the likelihood that artificial general intelligence (AGI) causes permanent, large-scale harm to humanity.

Unlike most calculators, there is no single formula. P(doom) is a subjective probability that depends on your assumptions about AI development timelines, alignment difficulty, and governance effectiveness. This doom calculator walks you through each assumption and combines them into a personal estimate.

Published estimates range from near 0% (Yann LeCun) to over 90% (Eliezer Yudkowsky). The median across 50+ public estimates is approximately 20%. See the full AI Risk Survey 2026 →

P(doom) = 1 − (1 − Path₁) × (1 − Path₂)
Path₁ = P(AGI) × P(Misalignment | AGI) × P(Catastrophe | Misalignment) × (1 − P(Governance)) · Path₂ = P(AGI) × P(Malicious use) × (1 − P(Governance))

Uncertainty Quantification

The 100× Disagreement Matters

When experts disagree by two orders of magnitude (<1% vs >99%), the takeaway is not that one side is right — it's that we face genuine uncertainty about unsolved problems. P(doom) is a tool for structuring uncertainty, not a prediction. The most rational response is to support AI safety research while acknowledging the limits of our current knowledge.

Why Experts Disagree by 100×

P(doom) estimates range from <1% to >99% because they depend on assumptions about unsolved open problems: whether the alignment problem is tractable, how quickly AI capabilities will advance, and whether governance mechanisms can keep pace with technology.

These are not empirical disagreements resolvable by more data — they are partly philosophical judgements about the nature of intelligence, human institutions, and the behaviour of optimisation processes at scale.

Educational tool: This calculator structures your uncertainty — it does not produce a ground truth. P(doom) is not a scientific metric with a knowable true value. Use it to explore your own assumptions.

Before you set P(AGI): Every major AI timeline prediction from the past 60 years was wrong — from Simon (1958) to Yudkowsky (2021). This systematic over-optimism matters for your estimate. Read our analysis of why forecasts keep failing →

What Drives Estimates Up or Down

Factors that increase P(doom)

Rapid capability scaling outpacing safety, race dynamics between labs or nations, difficulty of the alignment problem, inadequate governance, and dual-use misuse potential of powerful models.

Factors that decrease P(doom)

Capability plateau before dangerous levels, alignment proving tractable, international cooperation, significant lab safety investment, democratic oversight, and narrow AI remaining dominant longer than expected.

What you can do

Engage with AI governance debates. Support responsible AI institutions (ARC, MIRI, Anthropic safety teams, Centre for AI Safety). Stay informed. The civic response is more impactful than individual behaviour changes.

Frequently Asked Questions

P(doom) is the estimated probability that advanced AI development leads to catastrophic or existential outcomes for humanity. It is a heuristic used by AI safety researchers, not a formal scientific metric. Estimates range from <1% to >99%, reflecting genuine and deep disagreement about unsolved problems.
Geoffrey Hinton estimates 10–20% chance of extinction within 30 years (BBC Radio 4, Dec 2024) and up to 50% chance of AI surpassing human intelligence (BNN Bloomberg, Jun 2024). Eliezer Yudkowsky (MIRI) expresses P(doom) > 95%. Paul Christiano estimates ~50%. Yann LeCun (Meta) estimates <0.01%. The disagreement is real and substantive.
Rapid capability advancement leaving safety work behind, lack of alignment progress, competitive race dynamics between nations and companies, the difficulty of the alignment problem, inadequate governance, and misuse potential by malicious actors with access to powerful models.
AI capability plateaus before dangerous levels, alignment proving tractable, international cooperation developing, significant AI lab safety investment, democratic oversight mechanisms, and narrow AI remaining dominant far longer than pessimists expect.
This calculator is a thought experiment and educational tool, not actionable risk management. P(doom) estimates are a prompt to engage with AI governance debates and support safety research. Most impactful actions: engage with AI policy, support responsible AI institutions, stay informed.
The alignment problem is the challenge of ensuring that advanced AI systems pursue goals that are beneficial to humanity — even as they become more capable. It is hard because we cannot perfectly specify human values, and because capable optimisers may find unexpected ways to satisfy specified goals that violate the spirit of our intentions.
Artificial General Intelligence (AGI) is typically defined as AI that can perform any cognitive task a human can. Estimates of arrival range from 2028 (optimistic) to never (sceptics). The 2022 AI Impacts survey found median researcher estimates of ~50% chance by 2059. Timelines have shortened significantly since GPT-4.
Yes, meaningfully. Constitutional AI (Anthropic), RLHF fine-tuning, interpretability research (Mechanistic Interpretability), and scalable oversight are active areas. Whether progress is fast enough relative to capability scaling is the core dispute. Funding for safety research has grown substantially since 2022.

Formula & Sources

Bayesian Decomposition of P(doom)

P(doom) = P(AGI) × P(misalign|AGI) × P(catastrophe|misalign) + P(misuse) − overlap
  • P(AGI) — Probability of artificial general intelligence by 2100
  • P(misalign|AGI) — Probability of value-misalignment given AGI
  • P(catastrophe|misalign) — Probability of irreversible catastrophe given misaligned AGI
  • P(misuse) — Probability of catastrophic deliberate misuse (bioweapons, etc.)

Why estimates differ by 10,000×
  • Different definitions of 'doom': Extinction vs. permanent disempowerment vs. civilisational collapse.
  • Different timeframes: Some "within 30 years" (Hinton), others "within 100 years" (Ord, AI Impacts), others unconditional.
  • Conditional vs. unconditional: P(doom | AGI is built) vs. unconditional P(doom) — mathematically different numbers.
  • Selection bias: Survey medians (~5%) are consistently lower than public statements (~20%).
  • Alignment difficulty: The core dispute — whether aligning capable AI is tractable — explains most of the variance.
