Does improved upward social mobility foster frustration and conflict? A large-scale online experiment testing Boudon’s model

The rise of populism has reignited scholarly interest in the paradox of societal advancement leading to frustration and social tension. Globalization and digitalization have increased social opportunities for parts of the population, but a substantial portion of society feels disadvantaged, resulting in discontent. This study, rooted in Boudon’s model of relative deprivation, examines the mechanisms that fuel this frustration. We conducted an online experiment involving 2114 US-based MTurk participants, in which we manipulated the availability of status positions to create varying degrees of upward social mobility. We also varied group sizes to ensure robustness. We assessed relative deprivation with structural, subjective, and behavioral measures. For example, frustration was measured using the “joy-of-destruction game,” in which subjects had to make the costly decision to destroy part of another player’s winnings. Contrary to the model’s prediction, we found that the proportion of individuals who were worse off, the losers, decreased consistently as mobility increased. This outcome can be attributed to overentry in conditions of low mobility and underentry in conditions of intermediate or high mobility. The losers displayed increased frustration and hostility towards noncompetitors and winners. Intriguingly, winners also exhibited heightened hostility. However, at the aggregate level, hostile behavior did not surge as conditions improved. In our exploratory analyses at the individual level, we identified several distinct patterns. Risk-tolerant individuals and women were more likely to enter competition. Conversely, those with advanced education levels showed a decreased inclination to competitiveness. Risk-tolerant individuals reported greater feelings of frustration and displayed increased hostility. This effect was also observed particularly among politically right-leaning individuals.
