Stewart Brand said when introducing the work of Philip Tetlock that Brand's partner had given a talk in the 1980s to top Central Intelligence Agency people about the future of the Soviet Union. One scenario he raised was that the Soviet bloc might break up; a sign of this happening would be the rise of unknown Mikhail Gorbachev through the party ranks. A CIA analyst said that the presentation was fine, but there was no way the Soviet Union was going to break up in his lifetime or his children's lifetime. The analyst's name was Robert Gates.
