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 (99.5% here) when computing the expert median.
