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.

From emails to social media, from instant messaging to political memes, the way we produce and transmit culture is radically changing. This book uses, for the first time, cultural evolution theory to analyze how information spreads, and how it affects our behavior in the digital age. Online connectedness and digital media allows access to networks where cultural transmission is possible, increasing both the availability of cultural models (from whom we can copy) and our reach (the number of individuals who can copy from us). This poses new problems, and new opportunities (Chapter 1). A cognitive and evolutionary approach suggests that we are wary learners, and the power of social influence, either online or offline, is often overestimated (Chapter 2). The background developed in the initial chapters into the details of different online phenomena is used: the tendency to copy popular individuals (Chapter 3), popular opinions (Chapter 4), or exchange information only with same-minded individuals (Chapter 5). The spread of online misinformation is then scrutinized at length (Chapter 6), proposing that to understand the phenomenon we need to understand why, generally, some information is more successful in spreading than other. The last two chapters examine how online, digital, transmission is different from other forms of cultural transmission, providing more “fidelity amplifiers” (Chapter 7), and how this could affect future cultural cumulation (Chapter 8). Overall, it is proposed that a “long view” to the current situation, based on a personal perspective of cognitive and evolutionary approaches to culture, suggests that some of the dangers of digital, online, interactions may have been overestimated, and the opportunities still ahead of us are discussed.

Cultural evolution can provide a useful framework to understand how information is produced, transmitted, and selected in contemporary online, digital, media. The diffusion of digital technologies triggered a radical departure from previous modalities of cultural transmission but, at the same time, general characteristics of human cultural evolution and cognition influence these developments. In this chapter, I will explore some areas where the links between cultural evolution research and digital media seem more promising. As cultural evolution-inspired research on internet phenomena is still in its infancy, these areas represent suggestions and links with works in other disciplines more than reviews of past research in cultural evolution. These include topics such as how to characterise the online effects of social influence and the spread of information; the possibility that digital, online, media could enhance cumulative culture; and the differences between online and offline cultural transmission. In the last section I will consider other possible future directions: the influences of different affordances in different media supporting cultural transmission; the role of producers of cultural traits; and, finally, some considerations on the effects on cultural dynamics of algorithms selecting information.

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.

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.

Cognitive Preferences

The book concludes by mentioning some of the topics that it did not consider, such as concerns about data privacy, monopoly of social media companies, effects of digital media overuse on psychological well-being, or the fact that, for many people, online access is still barely achievable. Despite this, the research discussed in this book, which focuses on the informational aspects of our digital and online lives, suggests there are grounds for cautious optimism. Another problem is mentioned, which is thought to be urgent: the increase of available information also increases differences in how people access and use information, being advantageous for some and disadvantageous for others. How we will face this informational inequality will be a pressing problem in the next years. Finally the main message of the book with respect to cultural evolution theory is summarized: “culture” is not an entity with causal powers, but a property that artefacts, ideas, and behaviors have to a certain degree. Social influence is not blind and automatic, and the reasons why cultural traits become successful are many: cognitive preferences are only one of them.
