DESCRIPTION:We study the evolution of belief systems that suppress producti
 ve effort. These include concerns about the envy of others\, beliefs in the
  importance of luck for success\, disdain for competitive effort\, and trad
 itional supernatural beliefs in witchcraft or the evil eye. We show that su
 ch demotivating beliefs evolve when interactions are zero-sum in nature\, i
 .e.\, the gains for one individual tend to come at the expense of another. 
 Within a population\, our model predicts a divergence between material and 
 subjective payoffs\, with material welfare being hump-shaped and subjective
  well-being being strictly decreasing in demotivating beliefs. Across socie
 ties\, our model predicts a positive relationship between zero-sum thinking
  and demotivating beliefs) and a negative relationship between zero-sum thi
 nking (or demotivating beliefs and both material welfare and subjective wel
 l-being.  We test the predictions of the model using data from two samples
  in the Democratic Republic of Congo and from the World Values Survey. In t
 he DRC\, we find a positive relationship between zero-sum thinking and the 
 presence of demotivating beliefs\, such as concerns about envy and beliefs 
 in witchcraft. Globally\, zero sum thinking is associated with  skepticism
  about the importance of hard work for success\, lower income\, less educat
 ional attainment\, less financial security\, and lower life satisfaction. C
 omparing individuals in the same zero-sum environment\, we observe the dive
 rgence between material outcomes and subjective well-being predicted by our
  model.\\n\\nContact: Timothée Demont: timothee.demont[at]univ-amu.frEwen
