Smart people often go badly off the rails on politics

Intelligence does not confer political wisdom; very smart people frequently go disastrously off the rails on politics, as shown by Eric Hobsbawm affirming at the end of his life that the communist dream was worth hundreds of millions of deaths, Einstein admiring Stalin, and Bertrand Russell and von Neumann contemplating preventive war/nuclear strikes on the Soviet Union, demonstrating the capacity for surprising and unforeseeable ethical 'tilt' even in ethical minds.
