psychologists such as Walther Poppelreuter (1932) to lecture and write about political psychology that identified with Hitler. The psychologist Eric Jaensch (1883–1940) contributed the racist book The Anti-type (1933). United Kingdom At the turn of the century, Oxford University and Cambridge University introduced disciplinary political psychology courses such as "The Sciences of the Man", along with the foundation of the Psychological society (1901) and the Sociological society (1904). Oxford historian G. B. Grundy (1861–1948) noted political psychology (1917) as a sub-discipline of history. Motivated by social and political behavior during World War I, he deemed a new branch of historical science, "The Psychology of Men Acting in Masses". He referred to science to instrument the clarification of mistaken beliefs about intention. The intellectual Graham Wallas (1859–1932) implicated the significance of studying psychology in politics in Human Nature in Politics (1908). Wallace emphasized the importance of enlightening politicians and the public about the psychological processes in order to raise awareness on exploitation while developing control over one's own psychological intellect. He suggested in Great Society (1917) that recognition of such processes could help to build a more functional humanity. United States Across the Atlantic the first American to be considered a political psychologist was Harold Lasswell (1902–1978) whose research was also spurred by a sociological fascination of World War I. His work Propaganda Technique in the World War (1927) discussed the use of applying psychological theories in order to enhance propaganda technique. Lasswell moved to Europe shortly after where he started to tie Freudian and Adler personality theories to politics and published Psychopathology and Politics (1930). His major theories involved the motives of the politically active and the relation between propaganda and personality. Another contributing factor to the development of Political Psychology was the introduction of psychometrics and "The Measurement of Attitude" by Thurstone and Chave (1929). The methodological revolution in social science gave quantitative grounds and therefore more credibility to Political Psychology. Research into political preference during campaigns was spurred by George Gallup (1901–1984), who founded the "American Institute of Public Opinion". The 1940s election in America drew a lot of attention in connection with the start of World War II. Gallup, Roper and Crossley instigated research into the chances of Roosevelt being re-elected. Lazarsfeld, Berelson and Gaudet (1944) also conducted a famous panel study "The People's Choice" on the 1940s election campaign. These studies drew attention to the possibility
