Our paper on a super-rational solution to the tragedy of the commons published in Scientific Reports

Posted 14 Jan 2015 / 1

I am very pleased to announce that a paper that I worked on with collaborators Jun-Zhou He, Rui-Wu Wang, and Yao-Tang Li has been published in the open-access journal Scientific Reports. The paper, entitled “Asymmetric interaction paired with a super-rational strategy might resolve the tragedy of the commons without requiring recognition or negotiation“, considers how Read More

Evolution 2014: Day 0

Posted 20 Jun 2014 / 0

I started off this year’s Evolution meeting early. The conference is — at its core —  a four-day affair. But the days leading into the “official” start on Friday evening feature larger workshops aimed at building skills. I chose to attend the Experiencing Evolution workshop. Here’s what this session promised: Evolution is a key biological concept, Read More

Evolution 2014: Evolution of cooperation in the high school classroom? You bet!

Posted 20 Jun 2014 / 0

Will Ratcliff presented an absolutely amazing set of laboratories that explore the evolution of multicellularity (http://www.snowflakeyeastlab.com/). They can be done with high school or college students, and allow students to see the benefits of cooperation and the action of multilevel selection in a few weeks’ worth of laboratory work. Really impressive classroom activity design!

WNYC Money Talking “Helping Ordinary Americans Focus Of Fed Under Janet Yellen” Should the economy serve the society as a whole, or only some individuals in that society? Wow is it refreshing to hear a radio segment ask that question!

Writing and record-keeping as important tools in the evolution of large-scale human cooperation

This View of Life “The Role Of Writing And Recordkeeping In The Cultural Evolution Of Human Cooperation” What is also so interesting about written language is that it is another means of defining a group: only those who are literate and can read the particular recorded language can fully benefit from the cooperation fostered by Read More

My review of “Origins of Altruism and Cooperation” is published in QRB

Posted 30 Aug 2013 / 0

I am excited to report that my review of Origins of Altruism and Cooperation was just published in the Quarterly Review of Biology. Although it requires some work to get through, this collection presents a really important counter-narrative to the prevailing attitude in evolutionary biology that altruism is simply self-interest in disguise. The book uses Read More

Institute for Advanced Study “The Prisoner’s Dilemma” One of my favorite skateboarders when I was young was Natas Kaupas, an innovative skater who pioneered a lot of modern streetstyle. Natas was one of those skaters who could do things that no other skateboarders could, but he was not particularly successful in one arena that was Read More

Enforcing norms may be for personal gain, not to maintain social order (at least amongst Santa Barbara undergraduates)

Posted 28 Sep 2012 / 2

PLoS ONE “What Are Punishment and Reputation for?” Once again, a valuable and ingenious experiment over-reaches on the meaning of its finding, and the over-reach bleeds into the popular media. This is a really valuable experiment in that it asks about the scale at which social norms are enforced. It is significant that participants in Read More

What was the ‘big news’ at this year’s Ecological Society of America meeting? Given that this meeting is composed of so many different meetings running concurrently, this just might be an impossible question to answer fairly. But for me, this year’s meeting could be summarized as the ‘year of computational ecology’. At a great variety Read More
