Under what circumstances can copying lead to increased cultural diversity?

Abstract [en]

In many models of cultural evolution, agents learn cultural elements either by individual learning (innovation) or social learning (copying). This paper investigates what kind of learning, or combination of the two kinds, maximizes the total number of cultural elements known in the population. In a model where both kinds of learning are equally efficient, we find that this maximum is achieved when only individual learning is used. Analysis and simulation is used to investigate how much more efficient social learning has to be for a mixed solution to appear. Two possible reasons for social learning being more efficient than innovation are identified.

2011 (English)Doctoral thesis, comprehensive summary (Other academic)
Abstract [en]

Division of labor and division of knowledge are so important and common in society today that it is difficult to imagine a functional society where everyone knows the same things and performs the same tasks. In such a society everyone grows, or gathers, and prepares their own food, makes their own tools, builds their own house, and so on.

Cultural evolution is the field of research that studies the creation and diffusion of ideas and societies. It is very uncommon for these studies to take into account the effects of specialization. This thesis will show that specialization is of great importance to cultural evolution.

The thesis is divided into two parts: The first is an introduction to studies of specialization and division of labor. The thesis begins with an interdisciplinary survey of the research on division of labor and specialization, including both theoretic and empirical studies. Next is an introduction to modeling specialization and division of labor. This includes a general framework and a number of basic models of different aspects of specialization and division of labor.

Part two consists of four papers. The first paper studies the interaction between specialization and cultural cumulation. The second and third papers examine cultural cumulation, specifically the circumstances under which cultural knowledge increases and how cultural knowledge is distributed in the population. The last paper is a mathematical model of how specialization of knowledge (i.e. higher education) leads to social stratification.
