Cultural Evolution Theory

The tendency to copy the majority is the topic of the fourth chapter. The fact that online popularity produces long-tailed distributions is often presented as an argument to show the power of online social influence. However, long-tailed distributions are a trademark of many cultural domains, from first names to dog breeds. In addition, these distributions do not necessarily imply the existence of an individual-level tendency to prefer popular things, but they can be the result of bare availability: the more examples of an item, the more likely we will encounter it, and the more likely we will become interested in it. Conformity is next considered: as defined in cultural evolution, conformity implies an effective tendency to copy the majority. As for celebrities, various experiments are reviewed, and the author defends a view for which conformity is far from automatic, as it interacts with many other psychological tendencies. How digital technologies permit radically new forms of popularity advertisements, from the real-time quantification of “likes” in social media to the explosion of consumer reviews, or top-lists of virtually everything, is also examined and discussed in relation to cultural evolution theory.

AbstractRecently, a number of papers draw upon ideas from sexual selection and costly signaling theory to argue that conspicuous consumption has evolved as a sexually selected mating strategy. I outline what are considered to be the criteria for arguing that a trait is the outcome of sexual selection and I explore whether conspicuous consumption is sexual adaptation. Though I share the insight that evolutionary theory can contribute to our understanding of consumption behavior, I argue that existing evolutionary explanations of conspicuous consumption do not examine human evolved psychology and available evidence about past environments. I further argue that cultural evolution theory provides an alternative explanation of conspicuous consumption in modern environments. In particular, conspicuous consumption is understood as a pattern of behavior marked by specific social learning mechanisms. Such an approach reflects the analytical tools of cultural evolution theory and provides a classification of cognitive factors involved in consumption choices.

Simple Heuristics

Digital media have today an enormous diffusion, and their influence on the behaviour of a vast part of the human population can hardly be underestimated. In this review I propose that cultural evolution theory, including both a sophisticated view of human behaviour and a methodological attitude to modelling and quantitative analysis, provides a useful framework to study the effects and the developments of media in the digital age. I will first give a general presentation of the cultural evolution framework, and I will then introduce this more specific research program with two illustrative topics.The first topic concerns how cultural transmission biases, that is, simple heuristics such as "copy prestigious individuals" or "copy the majority", operate in the novel context of digital media. The existence of transmission biases is generally justified with their adaptivity in small-scale societies. How do they operate in an environment where, for example, prestigious individuals possess not-relevant skills, or popularity is explicitly quantified and advertised?The second aspect relates to fidelity of cultural transmission. Digitally-mediated interactions support cheap and immediate high-fidelity transmission, in opposition, for example, to oral traditions. How does this change the content that is more likely to spread? Overall, I suggest the usefulness of a "long view" to our contemporary digital environment, contextualised in cognitive science and cultural evolution theory, and I discuss how this perspective could help us to understand what is genuinely new and what is not.

High Rise

<p>With the continuous development and progress of society, the structure of high-rise buildings has been paid more and more attention by the engineering community. However, the existing high- rise structure design methods often have a lot of redundancy and have a lot of room for optimization. Most of the existing seismic design methods of high-rise structures are based on engineering experience and manual iterative methods, so that the efficiency of design can not meet the needs of the society. if the method of design automation is adopted, the workload of designers can be greatly reduced and the efficiency of structural design can be improved. Based on the digital modeling theory, this paper proposes a MAD automatic design algorithm, in which the designer provides the initial design of the structure, and the algorithm carries out the modeling, analysis, optimization and design of each stage of the structure, and finally obtains the optimal structure. The structural design module of this algorithm starts from the component level, when the component constraint design meets the limit requirements of the specification, it enters and completes the component constraint design and the global constraint design of the structure in turn. In this paper, taking a ten-story braced steel frame high-rise structure as an example, the optimal design is carried out, and its seismic performance is analyzed. the results show that the MAD automatic design algorithm can distribute the materials to each part reasonably, which can significantly improve the seismic performance of the structure and realize the effective seismic design.</p>

We analyse stories in Harry Potter fan fiction published on Archive of Our Own (AO3), using concepts from cultural evolution. In particular, we focus on cumulative cultural evolution, that is, the idea that cultural systems improve with time, drawing on previous innovations. In this study we examine two features of cumulative culture: accumulation and improvement. First, we show that stories in Harry Potter’s fan fiction accumulate cultural traits—unique tags, in our analysis—through time, both globally and at the level of single stories. Second, more recent stories are also liked more by readers than earlier stories. Our research illustrates the potential of the combination of cultural evolution theory and digital literary studies, and it paves the way for the study of the effects of online digital media on cultural cumulation.

Abstract After a brief flurry of attention following its introduction by Dawkins (1976), the concept of memes has largely disappeared from mainstream social and cognitive science discourse. A significant exception is Dennett’s (1995; 2017) writings on the philosophy of mind. In his most recent book, Dennett (2017) develops what he presents as a comprehensive account of cultural evolution, based on the claims that memes, defined as a “way of behaving (roughly) that can be copied, transmitted, remembered, taught…,” develop through evolutionary processes more or less identical to the processes through which biological organisms and their genes evolve, and that both memes and genes are active agents in their own evolution. Although Dennett presents some very interesting ideas about the co-evolution of culture and human brains, he couches his argument in a system of personification, organism, war, and object metaphors that implicitly assign mental activities including intending, competing, and planning to memes. In this paper I analyze Dennett’s metaphors and argue that they effectively distract attention from the psychological and cultural processes that actually determine whether a behavior pattern (i.e. a meme) is learned, remembered, and reproduced (none of which Dennett acknowledges). I then show how the substance of Dennett’s argument can be rephrased in language that avoids the obfuscating effect of his metaphors. In addition to countering a common metaphor-based misconception in evolution theory, this analysis illustrates the importance of close attention to the entailments of conceptual metaphors used as theoretical arguments.
