摘要：

We show that the frequency distributions of cultural variants, in three different real-world examples-first names, archaeological pottery and applications for technology patents-follow power laws that can be explained by a simple model of random drift. We conclude that cultural and economic choices often reflect a decision process that is value-neutral; this result has far-reaching testable implications for social-science research.
