    10–90%

    “[Rob Wiblin: “My guess is that it's more than 10% and less than 90%.”] Jan Leike: Yeah. That's probably the range I would give too.”

    Caveat: he agrees with the interviewer's range after calling p(doom) not 'a really useful question'. Counted at the 50% midpoint.

Context

“p(doom)” is shorthand for the probability that advanced AI leads to human extinction or a similarly irreversible catastrophe. Speakers rarely share one definition or time horizon, so compare numbers with care.

The Doom Index uses the midpoint of each person's latest stated range (50% here) when computing the expert median.
