The Special Science Dilemma and How Culture Solves It

This is the final version of the article. It first appeared from Taylor & Francis via http://dx.doi.org/10.1080/00048402.2014.987149I argue that there is a tension between the claim that at least some kinds in the special sciences are multiply realized and the claim that the reason kinds are prized by science is that they enter into a variety of different empirical generalizations. Nevertheless, I show that this tension ceases in the case of ‘cultural homologues’–such as specific ideologies, religions, and folk wisdom. I argue that the instances of such special science kinds do have several projectable properties in common due to their shared history of reproduction, and that the social learning involved means we should also expect these kinds to be multiply realized

A complex systems approach to constructing better models for managing financial markets and the economy

We outline a vision for an ambitious program to understand the economy and financial markets as a complex evolving system of coupled networks of interacting agents. This is a completely different vision from that currently used in most economic models. This view implies new challenges and opportunities for policy and managing economic crises. The dynamics of such models inherently involve sudden and sometimes dramatic changes of state. Further, the tools and approaches we use emphasize the analysis of crises rather than of calm periods. In this they respond directly to the calls of Governors Bernanke and Trichet for new approaches to macroeconomic modelling.The publication of this work was partially supported by the European Union’s Seventh Framework Programme (FP7/2007-2013) under grant agreement No. 284709, a Coordination and Support Action in the Information and Communication Technologies activity area (‘FuturICT’ FET Flagship Pilot Project).

A naturalistic theory of economic organization

We develop a theory of economic organization grounded in the naturalistic paradigm currently emerging at the intersection of biology and the behavioral and social sciences. The crux of this approach is the recognition that an understanding of the evolutionary origins of human organizational capabilities can inform theories of contemporary economic organization. Modern firms sustain large scale cooperation by applying cultural ‘work-arounds’ to tribal instincts that evolved from simultaneous within-group and between-group competition on a much smaller scale. We translate this insight into ten principles of economic organization

Biological and cultural group selection: Comments on Janet Landa’s paper

Janet Landa’s (2008) article is a study of the operation of cultural group selection and does not address, one way or the other, the relative importance of or the possible interactions between cultural and biological group selection. In that sense, it can fit comfortably within what my article in this issue calls the currently fashionable position. The currently fashionable position is that biological group selection is theoretically possible but its behavioral legacy is negligible. In contrast, cultural group selection has been a major force on human behavior, and pos

Social learning mechanisms and cumulative cultural evolution: is imitation necessary?

Cumulative cultural evolution has been suggested to account for key cognitive and behavioral attributes which distinguish modern humans from our anatomically similar ancestors, but researchers have yet to establish which cognitive mechanisms are responsible for this kind of learning, and whether these are unique to humans. We have shown that human participants’ cumulative learning is not always reliant on sources of social information commonly assumed to be essential. Seven hundred participants were organized into seventy microsocieties, and completed a task involving building a paper airplane. We manipulated the availability of opportunities for: imitation (reproducing actions); emulation (reproducing end results); and teaching. Each was independently sufficient for participants to show cumulative learning. Since emulative learning can elicit cumulative culture on this task, we conclude that accounts of the unusual complexity of human culture in terms of species-unique learning mechanisms do not currently provide complete explanations, and other factors may be involved

Influences on communication about reproduction: the cultural evolution of low fertility

The cultural norms of traditional societies encourage behavior that is consistent with maximizing reproductive success but those of modern post-demographic transition societies do not. Newson et al (2005) proposed that this might be because interaction between kin is relatively less frequent in modern social networks. Assuming that people's evaluations of reproductive decisions are influenced by a desire to increase their inclusive fitness, they will be inclined to prefer their kin to make fitness-enhancing choices. Such a preference will encourage the emergence of pronatal cultural norms if social networks are dense with kin. Less pronatal norms will emerge if contact between kin makes up a small proportion of social interactions. This article reports evidence based on role-play studies that supports the assumption of the kin influence hypothesis that evaluations of reproductive decisions are influenced by a desire to increase inclusive fitness. It also presents a cultural evolutionary model demonstrating the long-term effect of declining kin interaction if people are more likely to encourage fitness-enhancing choices when interacting with their kin than with nonrelatives
