Influentials, Networks, and Public Opinion Formation
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.… Expand
Experimental Study of Inequality and Unpredictability in an Artificial Cultural Market
Hit songs, books, and movies are many times more successful than average, suggesting that “the best” alternatives are qualitatively different from “the rest”; yet experts routinely fail to predict… Expand

We construct a tunable, real-time, remote-sensing, and non-invasive, text-based hedonometer. Expand
Re-examination of the "3/4-law" of metabolism.
We examine the scaling law B is proportional to M(alpha)which connects organismal resting metabolic rate B with organismal mass M, where alpha is commonly held to be 3/4. Since simple dimensional… Expand
An Experimental Study of Search in Global Social Networks
We report on a global social-search experiment in which more than 60,000 e-mail users attempted to reach one of 18 target persons in 13 countries by forwarding messages to acquaintances. We find that… Expand
Identity and Search in Social Networks
Social networks have the surprising property of being “searchable”: Ordinary people are capable of directing messages through their network of acquaintances to reach a specific but distant target person in only a few steps. Expand
Universal behavior in a generalized model of contagion.
We introduce a general model of contagion which, by explicitly incorporating memory of past exposures to, for example, an infectious agent, rumor, or new product, includes the main features of existing contagion models and interpolates between them. Expand
Measuring the Happiness of Large-Scale Written Expression: Songs, Blogs, and Presidents
The importance of quantifying the nature and intensity of emotional states at the level of populations is evident: we would like to know how, when, and why individuals feel as they do if we wish to better construct public policy, build more successful organizations, and, from a scientific perspective, more fully understand economic and social phenomena.

The Geography of Happiness: Connecting Twitter Sentiment and Expression, Demographics, and Objective Characteristics of Place

- 13 February 2013
We conduct a detailed investigation of correlations between real-time expressions of individuals made across the United States and a wide range of emotional, geographic, demographic, and health characteristics. Expand
A generalized model of social and biological contagion.
We present a model of contagion that unifies and generalizes existing models of the spread of social influences and microorganismal infections. Our model incorporates individual memory of exposure to… Expand
