Abstract
Based on Axelrod's adaptive culture model, the effects of the distribution of global information feedback are examined in two simulations. The first model is the generalized other model, where the most preferred features are hypothesized to represent the mental model of the most ordinary person and have the same influential power as real neighbors. The second model is the filter model, where neighbors are influential only when their traits are concordant with the most common trait among whole agents. In both simulations, the global distribution of information facilitated an earlier convergence and maintenance of cultural diversity. These counterintuitive results suggest that information about a global society, for example mass media coverage, would provide support for a local minority.
