Lipset received the MacIver Prize for Political Man (1960) and, in 1970, the Gunnar Myrdal Prize for The Politics of Unreason. In 2001, Lipset was named among the top 100 American intellectuals, as measured by academic citations, in Richard Posner's book, Public Intellectuals: A Study of Decline. Academic research "Some Social Requisites of Democracy: Economic Development and Political Legitimacy" One of Lipset's most cited works is "Some Social Requisites of Democracy: Economic Development and Political Legitimacy" (1959), a key work on modernization theory on democratization, and an article that includes the Lipset hypothesis that economic development leads to democracy. Lipset was one of the first proponents of the "theory of modernization", which states that democracy is the direct result of economic growth, and that “[t]he more well-to-do a nation, the greater the chances that it will sustain democracy.” Lipset's modernization theory has continued to be a significant factor in academic discussions and research relating to democratic transitions. It has been referred to as the "Lipset hypothesis" and the "Lipset thesis". The Lipset hypothesis has been challenged by Guillermo O'Donnell, Adam Przeworski and Daron Acemoglu and James A. Robinson. One of the debates as to how exactly how democracy emerges, is between endogenous or exogenous democratization. Endogenous democratization holds the argument, that democratization happens as a result of the countries previous history leading up to that point. So here economic development and expansion of the middle class play a crucial role. A proponent of this viewpoint is Charles Boix and Susan C. Stokes. Exogenous democratization on the other hand argues, that democratization happens as a result of external factors, such as the zeitgeist of pro-democracy political movements seen across the world from the third wave of democratization up until the 1990s. According to Adam Przeworski and Fernando Limongi, the reason for the correlation between economic wealth and democracy is for the simple reason, that once a country have transitioned to a democratic rule, it have a much better chance of stay democratic if it is wealthy where as poor countries most often fall back into autocratic rule. Political Man: The Social Bases of Politics Political Man (1960) is an influential analysis of the bases of democracy, fascism, communism (”working class authoritarianism”), and other political organizations, across the world, in the interwar
