<P> Milton Rokeach claimed that the defining difference between the left and right was that the left stressed the importance of equality more than the right . Despite his criticisms of Eysenck's tough - tender axis, Rokeach also postulated a basic similarity between communism and nazism, claiming that these groups would not value freedom as greatly as more conventional social democratics, democratic socialists and capitalists would and he wrote that "the two value model presented here most resembles Eysenck's hypothesis". </P> <P> To test this model, Milton Rokeach and his colleagues used content analysis on works exemplifying nazism (written by Adolf Hitler), communism (written by Vladimir Lenin), capitalism (by Barry Goldwater) and socialism (written by various socialist authors). This method has been criticized for its reliance on the experimenter's familiarity with the content under analysis and its dependence on the researcher's particular political outlooks . </P> <P> Multiple raters made frequency counts of sentences containing synonyms for a number of values identified by Rokeach--including freedom and equality--and Rokeach analyzed these results by comparing the relative frequency rankings of all the values for each of the four texts: </P> <Ul> <Li> Socialists (socialism)--freedom ranked 1st, equality ranked 2nd </Li> <Li> Hitler (Nazism)--freedom ranked 16th, equality ranked 17th </Li> <Li> Goldwater (capitalism)--freedom ranked 1st, equality ranked 16th </Li> <Li> Lenin (communism)--freedom ranked 17th, equality ranked 1st </Li> </Ul>
