Scientific American “Why We Help”

Posted 21 Jun 2012 / 1

The July issue of Scientific American features a cover story written by Martin A. Nowak called “Why We Help“. This very short article contains a brief review of Nowak’s “five rules” for cooperation, a little bit of connection to experimental work in real organisms, and some hazy conjecture concerning what makes humans cooperate. It seems as Read More

Understanding the effects of asymmetry and relatedness on social volunteerism

Posted 06 Jun 2012 / 0

I am proud to announce the recent publication of a new paper in the Chinese Science Bulletin with collaborators from Yunnan University and the Kunming Institute of Zoology in Kunming, China. Our paper, entitled “Cooperation in an asymmetric volunteer’s dilemma game with relatedness“, uses a game-theoretic analysis of a new variant to the volunteer’s dilemma to Read More

Evolutionary Games Infographic Project launches with its first release of graphic packages

Posted 04 Jun 2012 / 0

In the Fall of 2011 I began a new project with Greg Riestenberg, a graduate student in Pratt’s Communications Design program. Given the ubiquity — especially in recent times — of evolutionary game theory, you would think that someone would have produced a set of clear conceptual images depicting how the most important of these games work; Read More

Evolutionary Games Infographic Project: Ultimatum Game “conceptual” images

Posted 15 Mar 2012 / 0

UPDATE: The images discussed below are now available for free use on the Evolutionary Games Infographic Project page. To complete the set of Evolutionary Games Infographic images that Greg Riestenberg and I have been working on, we created a set of “conceptual” matrices for the Ultimatum Game (UG). These are meant to complement the conceptual images we Read More

UPDATE: The images discussed below are now available for free use on the Evolutionary Games Infographic Project page. This semester I have been working with Greg Riestenberg, a graduate student in Pratt’s Communications Design program, to come up with a new series of images designed to explain some common evolutionary games. Our first images for the Read More
