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

Think that the DNA transfer is only from parents to offspring? Think again!

Science Now “Bearing Sons Can Alter Your Mind” Once again, epigenetic effects complicate our understanding of biological evolution! Two interesting omissions in this article: The fail to point out that female fetuses might also be donating DNA to mom: it is just easier to detect the male DNA unequivocally; and The real implication here is Read More

Can playing games make the world a better place?

Posted 27 Sep 2012 / 1

One of the very talented students I work with in the¬†Envirolutions¬†club, Rhett Bradbury, pointed me towards the work of Jane McGonigal, a game designer and evangelist for the idea that games can save the world. For Rhett, her work is important to his Master’s thesis in graphic design, as he is considering how to move Read More

Can proper education allow reputation to foster action on climate change?

Posted 20 Sep 2012 / 0

Daily Kos “Evolution, Cooperation, and Climate” I like some of the ideas that are expressed here. In a culture where the threat of climate change was well-understood, those who seek to deny its existence would be marginalized. It is true that history might judge those currently fighting against action on climate change, but current reputation Read More

Chimpanzees, our closest relatives, cannot triangulate punishment

Posted 20 Sep 2012 / 0

Proceedings of the National Academy of Sciences “No third-party punishment in chimpanzees” This is pretty astonishing, but perhaps not entirely surprising. As numerous other studies have shown, there are many qualitative differences in the cognition and resulting behaviors of humans and chimpanzees. Whether the fact that chimps do not maintain a sense of ‘social justice’ Read More

What’s ironic is that the creationists do not realize that we evolutionists might be trying to understand their success

Posted 20 Sep 2012 / 0

CreationRevolution “If Morality Evolved, Is It Righteous?” It is striking how this reaction lacks any self-consciousness. Research like that referred to in this post is a potential means of understanding how religions and their particular constructed righteousness (in other words their morals, what they believe ought to be) can succeed.

Agent-based modeling instead of game theory: I agree!

Posted 20 Sep 2012 / 0

The Society Pages “Progressing from game theory to agent based modelling to simulate social emergence” This is a nice albeit pretty choppy explanation for why we should not listen to orthodox/traditional game theorists. The only argument I see missing here is that game theory relies on the assumption of a well-mixed population: even the Prisoner’s Read More

Punishment, properly rewarded, can promote cooperation without corruption

Posted 20 Sep 2012 / 0

Public Library of Science ONE “Evolving Righteousness in a Corrupt World” In the race to build the next over-simplified model of cooperative dynamics, it will be interesting to see how the media runs with this one. Is this a “scientists discover the evolutionary rationale for honorable police” moment? I think it is important to take Read More
