Popularity

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.
