On becoming a psychopath

Posted 24 Oct 2012 / 0

The Chronicle of Higher Education “Psychopathy’s Double Edge” There are so many fascinating elements to this article and what it says about human behavior. First, there is the fact that most people walk around with a very potent regulatory of behavior, one that suppresses both impulses that would put oneself at risk and drives that Read More

Freeman Dyson calls the Prisoner’s Dilemma “an amusing toy”

Posted 17 Oct 2012 / 0

This is from the events calendar of Howard University, where Freeman Dyson gave a talk on October 12, 2012. Just in case this disappears from the web, here is the abstract of his talk: “The Prisoner’s Dilemma: Is it a model for the evolution of cooperation in the real world, or is it only a Read More

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

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.

Punishment, properly rewarded, can promote cooperation without corruption

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

Despite great press for Dyson, the Iterated Prisoner’s Dilemma is still not the solution to human cooperation

Posted 19 Sep 2012 / 0

The Chronicle of Higher Education “To the Trickster Go the Spoils” I really appreciate that Freeman Dyson acknowledges so clearly in this article that the fact that he has found a deceitful solution to the Iterated Prisoner’s Dilemma does not warrant radically shifting our understanding of human cooperation. The IPD and other game theory constructs Read More

“School of Life” acknowledges the values in religion worth preserving

Posted 10 Sep 2012 / 0

On Being “Alain de Botton on a School of Life for Atheists” Religion for Atheists What I find very interesting about this philosopher’s approach are his implicit memetic assumptions: that religions have nested within their complex cultural structure extractable “ways of living” that are valuable to believers and non-believers alike.

ESA 2012 Overall Impressions

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

Matthew Zimmerman on how international relations views the evolution of groups

Social Evolution Forum “Matthew Zimmerman: Groups as the Most Natural and Useful Level of Analysis (a comment on Pinker)” I am not sure which frustrates me more: The contention that genes are the only “target” of selection; or The contention that selection on organisms is the only level at which selection occurs; or The contention Read More

If your loners are truly loners they won’t punish, and cooperation thrives even in the presence of antisocial punishment

Posted 28 Jun 2012 / 1

Last summer I discussed a paper by Rand and Nowak that explored the dynamics of antisocial punishment in groups composed of cooperators, defectors, and loners playing a public goods game. In a conventional public goods game, at least some players must make a contribution in order to reap group reward. Cooperators make that contribution and Read More
