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

Do humans form genetically similar social groups independent of kinship?

Posted 26 Jul 2014 / 1

Proponents of kin selection as the most parsimonious explanation of how cooperation evolves face a problem when it comes to humans: counter to the predictions of kin selection theory, humans aim a fair amount of altruism at non-kin. While we do not aim our helping behaviors solely at our relatives, we also do not randomly Read More

Donald Trump saves CitiBike, proving that selfishness and cooperation are no longer opposed

Posted 01 Apr 2014 / 0

WNYC The Brian Lehrer Show “A New Citi Bike Savior: Donald Trump?” Although this story is disheartening, it truly is inspiring that so many enlightened and savvy New Yorkers called in to decry Donald Trump’s role in commercializing the previous-unsullied CitiBike Program.

In bird reproduction, parasitism and cooperation coevolve

Posted 21 Jan 2014 / 0

Science “How Cooperation Defeats Cheats” Science “Brood Parasitism and the Evolution of Cooperative Breeding in Birds” Live Science “How Birds Cooperate to Defeat Cuckoos” It is fascinating that being a cooperative breeder is both attractive to parasites (because they can achieve better reproductive success by successfully parasitizing the nest of cooperative breeders) and the best way to 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

Think the Milgram Experiments tell us something definitive about human nature? Think again!

Posted 21 Aug 2013 / 0

WNYC The Leonard Lopate Show “The Untold Story of the Notorious Milgram Psychology Experiments” This great feature uncovers two major sources of scientific distortion: Milgram himself selectively reported his results in order to tell a more sensational story; and Media depictions, fueled by popular preconceptions, further filtered and distorted the meanings of Milgram’s scientific results. Both Read More

Is selective rejection of science really a problem?

Posted 18 Jan 2013 / 1

In a recent short opinion piece (Scientific American “Creation, Evolution and Indisputable Facts“), Jacob Tanenbaum argues that selectively rejecting evolutionary biology is dangerous to the scientific culture of America. He rightly points out that our populace does not reject science as a whole, but instead picks and chooses what science to doubt and what science Read More

Lee Alan Dugatkin blesses Slate with a piece on Kropotkin

Posted 31 Oct 2012 / 0

Slate “The Russian Anarchist Prince Who Challenged Evolution” I really appreciate the fact that Dugatkin uses Kropotkin to bring to light that Darwinian evolution has been — even in the time and work of Darwin — a process that was imagined to involve both competition and cooperation. Only in recent times has evolution become synonymous Read More
