Knowledge creation has been a pivotal ingredient of endogenous growth theory to understand differences in standards of living across countries. Yet, the identification of key drivers explaining cross-country differences in knowledge creation still remains a topic of central interest in this research field. In this paper, I provide a framework to hypothesize and empirically test the persistent effects of novelty-seeking traits on cross-country differences in scientific knowledge creation. The results suggest a positive and statistically significant relationship between both outcomes that is consistent with the hypothesis that the prevalence of novelty-seeking traits in society facilitates scientific knowledge creation through beneficial human behaviors related to risk-taking and explorative behavior. The empirical findings remain qualitatively unaffected when controlling for additional historical, biogeographical, and socioeconomic factors that appear as additional important determinants in the creation of scientific knowledge in society.
