This dataset accompanies chapter 3 and is based on Hoyer K, Zeelenberg M., & Breugelmans, S.M. (2022). Greed: What is it good for? Manuscript under review. Article abstract: What is greed good for? This is an important question, as greed is omnipresent, suggesting some evolutionary benefits, but almost uniformly condemned. In a representative sample of the Dutch population, we examined two main questions. First, we examined whether greedy people had more economic, evolutionary, and psychological success than less greedy people. We adopted the approach that Eriksson et al. (2020) recently used to study the benefits of selfishness. We found that greedy individuals had more economic success, sometimes more and sometimes less evolutionary success, and less psychological success, than their less greedy counterparts. Second, we aimed to disentangle greed from self-interest in relation to these indicators. Here we found that greed differed from self-interest in terms of economic success, and partly in terms of evolutionary success (with greed being slightly more advantageous), but that they are similar in terms of psychological success.
