P(doom) Calculator
"P(doom)" is the probability that advanced AI leads to catastrophe for humanity. It isn't one number. It's the product of several uncertain judgments. Move the sliders below to set your own view on each, and the calculator combines them into a single estimate you can compare against leading researchers.
The estimate is a simple multiplicative chain, each factor is the conditional probability of the next step, so the overall risk is their product:
P(doom) = P(AGI) × P(unaligned) × P(gets power) × P(catastrophe) × P(no recovery)
This mirrors the structure of Joe Carlsmith's 2021 report Is Power-Seeking AI an Existential Risk?, which decomposed the question into a chain of premises and multiplied point estimates together. The model is deliberately transparent rather than precise: its value is in making explicit which judgment is driving your number.
Note: a strict product assumes the steps are independent, which is a simplification, in reality these judgments correlate. Treat the output as a reasoning aid, not a forecast.

Whatever your P(doom), the case for action holds.
Even a low probability of an irreversible, civilization-scale outcome carries enormous expected cost. That is the whole argument for treating AI safety as a serious priority now. Get our briefings on the risk and what can be done about it.
