TL;DR: The authors examined the influence of influential individuals in the formation of public opinion and found that large cascades of influence are driven not by influential individuals but by a critical mass of easily influenced individuals.
Abstract: A central idea in marketing and diffusion research is that influentials—a minority of individuals who influence an exceptional number of their peers—are important to the formation of public opinion. Here we examine this idea, which we call the “influentials hypothesis,” using a series of computer simulations of interpersonal influence processes. Under most conditions that we consider, we find that large cascades of influence are driven not by influentials but by a critical mass of easily influenced individuals. Although our results do not exclude the possibility that influentials can be important, they suggest that the influentials hypothesis requires more careful specification and testing than it has received.

TL;DR: It is found that scalable cooperation---that is, high levels of cooperation in large populations---can be achieved in sparse networks, assuming that individuals are able to sever ties unilaterally and that new ties can only be created with the mutual consent of both parties.
Abstract: We study the problem of cooperative behavior emerging in an environment where individual behaviors and interaction structures coevolve. Players not only learn which strategy to adopt by imitating the strategy of the best-performing player they observe, but also choose with whom they should interact by selectively creating and/or severing ties with other players based on a myopic cost-benefit comparison. We find that scalable cooperation---that is, high levels of cooperation in large populations---can be achieved in sparse networks, assuming that individuals are able to sever ties unilaterally and that new ties can only be created with the mutual consent of both parties. Detailed examination shows that there is an important trade-off between local reinforcement and global expansion in achieving cooperation in dynamic networks. As a result, networks in which ties are costly and local structure is largely absent tend to generate higher levels of cooperation than those in which ties are made easily and friends of friends interact with high probability, where the latter result contrasts strongly with the usual intuition.

TL;DR: In this paper, the authors argue that most big companies should not rely on viral marketing to spread the word about their products and brands, and propose a new model called "Big Seed Marketing" that combines the power of traditional advertising with the extra punch provided by viral propagation.
Abstract: In spite of the recent popularity of viral marketing, we argue that most big companies should not rely on it to spread the word about their products and brands. Instead, we propose a new model called “Big Seed Marketing” that combines the power of traditional advertising with the extra punch provided by viral propagation. Between traditional advertising and viral marketing is an important gap that can be filled by big companies looking for an advantage in the market place and a better return on their advertising and marketing dollar.

TL;DR: Recently, this article showed that reliable hit prediction is impossible no matter how much you know, regardless of how much knowledge you have about the movie industry, and that the experts may simply not be as smart as they would like us to believe.
Abstract: As anyone who follows the business of culture is aware, the profits of cultural industries depend disproportionately on the occasional outsize success — a blockbuster movie, a best-selling book or a superstar artist — to offset the many investments that fail dismally. What may be less clear to casual observers is why professional editors, studio executives and talent managers, many of whom have a lifetime of experience in their businesses, are so bad at predicting which of their many potential projects will make it big. How could it be that industry executives rejected, passed over or even disparaged smash hits like “Star Wars,” “Harry Potter” and the Beatles, even as many of their most confident bets turned out to be flops? It may be true, in other words, that “nobody knows anything,” as the screenwriter William Goldman once said about Hollywood. But why? Of course, the experts may simply not be as smart as they would like us to believe. Recent research, however, suggests that reliable hit prediction is impossible no matter how much you know — a result that has implications not only for our understanding of best-seller lists but for business and politics as well.
