Cultural worldviews, whether zero-sum or positive-sum, shape societal interactions. Social influence and authority can perpetuate inaccurate beliefs, leading to cultural evolutionary mismatch even when suboptimal.
Area of Science:
- Social psychology
- Cultural evolution
- Behavioral economics
Background:
- Societies exhibit varying degrees of zero-sum (one's gain is another's loss) versus positive-sum (mutual benefit) worldviews.
- These worldviews influence individual decisions regarding work, investment, collaboration, and social policy acceptance.
Purpose of the Study:
- To model how zero-sum and positive-sum worldviews interact within a population under varying environmental conditions.
- To investigate the impact of social influence mechanisms, including assortative matching, peer conformity, and cultural authorities, on worldview propagation.
- To identify conditions that lead to cultural evolutionary mismatch, where beliefs are misaligned with the environment.
Main Methods:
- Agent-based modeling of dyadic interactions in a heterogeneous population.
- Simulation of stochastic environmental shifts between cooperative and competitive states.
- Analysis of social influence dynamics: assortative matching, peer conformity, and authority-driven belief alteration.
Main Results:
- In the absence of social influence, the more accurate worldview (aligned with the environment) prevails.
- Assortative matching can favor positive-sum worldviews, even if less probable.
- Peer conformity and authority interventions can lead to the persistence of inaccurate worldviews and cultural evolutionary mismatch, especially when authorities promote suboptimal beliefs.
Conclusions:
- Social influence mechanisms significantly impact the persistence and spread of zero-sum versus positive-sum worldviews.
- Cultural evolutionary mismatch is a plausible outcome, driven by conformity and authority, particularly in environments with strong social pressures.
- Understanding these dynamics is crucial for addressing societal polarization and promoting adaptive cultural change.
