A Model of Genetic Variation in Human Social Networks (2008)
Fowler, James H., Dawes, Christopher T., Christakis, Nicholas A.
Social networks influence the evolution of cooperation and they exhibit strikingly systematic patterns across a wide range of human contexts. Both of these facts suggest that variation in the...
Community Structure in Congressional Cosponsorship Networks (2007)
Zhang, Yan, Friend, A. J., Traud, Amanda L., Porter, Mason A., Fowler, James H., Mucha, Peter J.
We study the United States Congress by constructing networks between Members of Congress based on the legislation that they cosponsor. Using the concept of modularity, we identify the community...
The Spread of Obesity in a Large Social Network over 32 Years (2007)

The Genetic Basics of Political Cooperation (2006)
Fowler, James H., Baker, Laura A., Dawes, Christopher T
Cooperation has been a focus of intense interest in the biological and social sciences. Yet in spite of a tremendous effort to develop evolutionary models and laboratory experiments that explain the...
Altruistic punishment and the origin of cooperation
How did human cooperation evolve? Recent evidence shows that many people are willing to engage in altruistic punishment, voluntarily paying a cost to punish noncooperators. Although this behavior...

A number of scholars have demonstrated that voter turnout is influenced by the costs of processing information and going to the polls, and the policy benefits associated with the outcome of the...
Egalitarian Punishment in Humans
James H. Fowler, Tim Johnson, Richard McElreath, Oleg Smirnov
Participants in laboratory public goods games are often willing to decrease the earnings of others at a cost to themselves. What motivates this behaviour is unclear: in the conventional public goods...
Heritability of cooperative behavior in the trust game
Cesarini, David, Dawes, Christopher T., Fowler, James H., Johannesson, Magnus, Lichtenstein, Paul, Wallace, Björn
Although laboratory experiments document cooperative behavior in humans, little is known about the extent to which individual differences in cooperativeness result from genetic and environmental...
