Paul R. Ehrlich

American biologist — Stanford — whose The Population Bomb (1968) predicted mass starvation by the 1980s from overpopulation — which proved incorrect — making him the most cited example of catastrophist scientific prediction failure.

Creates The Population Bomb as the model catastrophist prediction — Ehrlich's confident 1968 prediction (that hundreds of millions would starve to death in the 1970s-80s) proved spectacularly wrong due to the Green Revolution; his refusal to substantially update his views despite the failure is the most frequently cited case study in how doomsday predictions generate celebrity rather than accountability.
