Inglehart and PippaNorrisAbstract Rising support for populist parties has disrupted the politics of many Western societies . What explains this phenomenon ? Two theories are examined here . Perhaps the most widelyheld view of mass support for populism the economic insecurity perspective emphasized the consequences of profound changes transforming the workforce and society in postindustrial economies . Alternatively , the cultural backlash thesis suggests that support can be explained as a retro reaction by oncepredominant sectors of the population to progressive value change . Overall , we find the most consistent evidence supporting the cultural backlash thesis .
