Hadley Cantril (1906–1969) was an American researcher of public opinion.
==Early career==
Born in Utah, he was educated at Dartmouth College and received his Ph.D. from Harvard. He joined the faculty of Princeton during 1936 and later became chairman of Princeton University Department of Psychology. He was a member of the Princeton Radio Research Project before it relocated to Columbia during the early 1940s, and was the main author of The Invasion from Mars, an academic study of the 1938 radio broadcast of the story "The War of the Worlds", which frightened many people. During 1940 he served as a consultant to the Office of the Coordinator of Inter-American Affairs.
 Cantril's later psychological work included collaboration with Adelbert Ames, Jr. developing a transactional method for studying human perception, as well as other research of humanistic psychology.Public opinion and polling around the world: a historical encyclopedia, Volume 1 By John Gray Geer, pg 389-390
==Public Opinion Research==
Though trained as a psychologist, Cantril's most important work concerned the then-new topic of Public Opinion research. Influenced initially by the success of George Gallup and Elmo Roper during the 1936 presidential election, Cantril sought to apply their systematic polling technique to academic social psychology.Public opinion and polling around the world: a historical encyclopedia, Volume 1 By John Gray Geer, pg 388 Cantril was a founding editor of Public Opinion Quarterly. During 1940 he initiated Princeton University's Office of Public Opinion Research. and from autumn 1940 onwards provided the Roosevelt administration with confidential information about American public opinion, particularly regarding the war in Europe.Public opinion and polling around the world: a historical encyclopedia, Volume 1 By John Gray Geer, pg 389 During 1942 Cantril conducted a small-sample survey of Vichy officials in Morocco, prior to Operation Torch, that revealed the intensity of the anti-British sentiment of the French forces there, and influenced the disposition of forces during the operation (American troops landing near Casablanca, with mixed forces at Oran and Algiers).
During 1955 he initiated the Institute for International Social Research with Lloyd A. Free."Lloyd A. Free, 88, is dead; Revealed Political Paradox" New York Times, November 14th, 1996. Cantril had previously provided data on public opinion in America and abroad to Presidents Roosevelt and Eisenhower, and the IISR was often asked by agencies of United States Government to conduct small-sample public opinion polls in foreign countries."Worldwide Propaganda Network Built by the C.I.A." New York Times, December 26th, 1976 Notably, Cantril and Free conducted a poll of Cuba during 1960 demonstrating great support for Fidel Castro, which was overlooked during the presidential transition between Eisenhower and Kennedy and only read after the Bay of Pigs Invasion fiasco."Lloyd A. Free, 88, is dead; Revealed Political Paradox" New York Times, November 14th, 1996. Cantril's most-cited work is The Pattern of Human Concerns, notable for the development of the self-anchoring scale (also known as "Cantril's Ladder"). Cantril and Free also first discovered the paradox that American voters tend to oppose 'big government' in general while supporting many specific liberal social programs.
During the late 1950s, Cantril served on the International Objectives and Strategies panel of the Rockefeller Brothers' Special Studies Project.
