Cultural Transmission in Cycles: The Production and Maintenance of Cumulative Culture

Abstract

The ‘information cycle’ is an evolutionary model of the processes of gene/culture maintenance and change. This paper reports the first naturalistic experimental study designed to collect information data that can illuminate the mechanisms of ‘culture’ production and sharing in information cycles. It is an analysis of conversation among university students in Taiwan. A junior class of 32 students utilized pencil and paper (P&P) diaries to record conversation topics over a three week period. It was expected that some topics of special interest would be shared widely as they were passed among speakers through repeated information cycles. This type of linear transmission did appear. However, of great interest, the majority of widely shared topics were initiated by larger scales of information cycles, it is argued, specifically popular media, education, social media, ritual, and legal scales, which triggered cascades of conversation sharing. This result indicates that the sharing of cultural information relies on statistical, not linear, transmission, in which topics are shared imprecisely but repeatedly, permitting the construction of shared knowledge. Further, it indicates that culture is shared in a hierarchy of transmission cycles, which differ in space, cycle time, input, and copy fidelity. Further, it indicates that culture must be maintained against depreciation by repeated cycling in information cycles. Cultural transmission is indeed a complex, statistical, multi-scaled process that requires a nested model of information cycles as I have proposed.
