This paper addresses the effect of degree-mixing patterns on the behavioral diversity in a scale-free structured population. In a high-mutation situation, a structured population with assortative mixing by degrees inhibits the diversity of collective behaviors as the highly connected individuals are clustered more closely to compose a core group of dominant behaviors. While disassortative mixing patterns barely influence the behavioral diversity of the population. The results are helpful to better understand the evolutionary dynamics of the collective behaviors in a scale-free structured population.
