Ronald Inglehart argues that economic development, cultural change, and political change go together in coherent and even, to some extent, predictable patterns. This is a controversial claim. It implies that some trajectories of socioeconomic change are more likely than others--and consequently that certain changes are foreseeable. Once a society has embarked on industrialization, for example, a whole syndrome of related changes, from mass mobilization to diminishing differences in gender roles, is likely to appear. These changes in worldviews seem to reflect changes in the economic and political environment, but they take place with a generational time lag and have considerable autonomy and momentum of their own. But industrialization is not the end of history. Advanced industrial society leads to a basic shift in values, de-emphasizing the instrumental rationality that characterized industrial society. Postmodern values then bring new societal changes, including democratic political institutions and the decline of state socialist regimes. To demonstrate the powerful links between belief systems and political and socioeconomic variables, this book draws on a unique database, the World Values Surveys. This database covers a broader range than ever before available for looking at the impact of mass publics on political and social life. It provides information from societies representing 70 percent of the world's population--from societies with per capita incomes as low as $300 per year to those with per capita incomes one hundred times greater and from long-established democracies with market economies to authoritarian states.
Ronald F. Inglehart (born September 5, 1934) was a political scientist at the University of Michigan. He was director of the World Values Survey, a global network of social scientists who have carried out representative national surveys of the publics of over 80 societies on all six inhabited continents, containing 90 percent of the world's population. The first wave of surveys for this project was carried out in 1981 and the latest wave was completed in 2014. Since 2010 Inglehart was co-director of the Laboratory for Comparative Social Research at the National Research University - Higher School of Economics in Moscow and St Petersburg. This laboratory has carried out surveys in Russia and eight ex-Soviet countries and is training Phd.-level students in quantitative cross-national research methods.
In the seventies Inglehart began developing an influential theory of Generational Replacement causing intergenerational value change from materialist to postmaterialist values that helped shape the Eurobarometer Surveys, the World Values Surveys and other cross-national survey projects. Building on this work, he subsequently developed a revised version of Modernization theory, Evolutionary Modernization Theory, which argues that economic development, welfare state institutions and the long peace between major powers since 1945, are reshaping human motivations in ways that have important implications concerning gender roles, sexual norms, the role of religion, economic behavior and the spread of democracy.
