The paper develops an evolutionary‑game‑theoretic model in which individuals form "demotivating beliefs" (e.g., skepticism about hard work, witchcraft, envy) that suppress effort when the surrounding economic environment is perceived as zero‑sum. The model yields several propositions: (1) zero‑sum environments foster stronger demotivating beliefs; (2) demotivating beliefs can raise material welfare up to an interior optimum (hump‑shaped relationship) while always reducing subjective well‑being; (3) across societies, higher zero‑sumness and stronger demotivating beliefs are linked to lower income, education, and happiness. Empirically, the authors first validate a zero‑sum perception measure derived from the World Values Survey/European Values Study, showing it correlates with low economic growth during respondents’ youth. Using pooled WVS/EVS data (hundreds of thousands of respondents across 99 countries), they estimate OLS regressions linking zero‑sum perceptions to six demotivating‑belief indices (hard‑work efficacy, poverty‑effort attribution, humiliation from receiving money, importance of success, importance of work). All coefficients are positive and significant, indicating stronger demotivating beliefs in more zero‑sum contexts. They then relate zero‑sum perceptions to five material‑welfare outcomes (income decile, class, savings, education, occupational skill) and find uniformly negative effects. Subjective‑well‑being (happiness, life satisfaction) also declines with zero‑sum perceptions and with each demotivating belief. Finally, holding zero‑sumness constant, they partition the sample into deciles of perceived zero‑sumness and plot the relationship between demotivating beliefs and income, revealing a hump‑shaped curve consistent with the model, while happiness shows a monotonic convex decline. The paper concludes that demotivating belief systems evolve in zero‑sum environments, improve material outcomes only up to a point, and systematically erode well‑being, offering a unified explanation for cross‑societal variation in effort, growth, and happiness.

Within‑Group Analyses: Income and Happiness Patterns
Holding zero‑sumness constant, the sample is partitioned into deciles of perceived zero‑sumness. Plots of demotivating‑belief intensity versus income display a hump‑shaped curve (interior optimum), whereas plots of belief intensity versus happiness show a monotonic convex decline, providing within‑group validation of the theoretical predictions.
