Two hypotheses
Inglehart (1977) explained value change with two hypotheses. The scarcity hypothesis holds that people place the greatest value on what is in short supply: those who lived with hunger and the threat of war prioritize economic and physical security, but once these are satisfied, needs for belonging, self-expression and self-realization become important. The socialization hypothesis holds that basic values are formed by conditions during one's formative years and change little in adulthood, so value change occurs slowly through generational replacement rather than within individuals. Inglehart (1971) reported that young Western Europeans raised in postwar affluence were much more postmaterialist than their parents.
Measurement and the World Values Survey
Inglehart created a simple index asking respondents to choose the two most important goals among maintaining order in the nation, fighting rising prices, giving people more say in government decisions and protecting freedom of speech; those choosing the first two are classified as materialists and those choosing the last two as postmaterialists. The measure was carried into the World Values Survey and used to track value change in about 100 countries. Inglehart (1990) reported a steady rise in the share of postmaterialists in advanced societies, and Inglehart and Baker (2000) showed that modernization changes values while religious and cultural traditions leave lasting imprints. The theory has also been used to explain new social movements, such as environmental and women's movements, and the rise of Green parties.
Critiques and cultural backlash
Clarke and Dutt (1991) criticized the index for depending heavily on the prices item, making it sensitive to short-term economic conditions such as unemployment. Inglehart and Abramson (1994) countered that generational effects remain after controlling for economic conditions. Others argue that placing materialism and postmaterialism on a single dimension is an oversimplification. More recently, Norris and Inglehart (2019) argued that the spread of postmaterialist values provoked a cultural backlash among older and more conservative groups who felt threatened, fueling the growth of authoritarian populism seen in Trump's election and Brexit. The theory thus continues to be discussed, alongside modernization theory, as a leading account linking value change and political change.
FAQ
- What is postmaterialism in simple terms?
- It is the idea that people raised in affluent conditions, where basic needs are met, come to value freedom, participation, the environment and quality of life more than money and security. This change is thought to happen slowly as generations replace one another.
- How is postmaterialism measured?
- The best-known method asks people to choose the two most important goals among maintaining order, fighting rising prices, giving people more say and protecting free speech. Choosing the first two marks a materialist; choosing the last two marks a postmaterialist.
