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

Rachel Carson still under attack for bringing her values to bear on her science

Posted 17 Sep 2012 / 0

Slate “Rachel Carson Didn’t Kill Millions of Africans: How the 50-year-old campaign against Silent Spring still distorts environmental debates” There is a lot of interesting stuff here, including a fascinating view into how scientific findings get processed by the public (both left and right leaning). The ad hominem attacks on Carson are interesting because they seem Read More

Sometimes our simulations have more to tell than we first see

Theory, Evolution, and Games Group “Bifurcation of cooperation and inviscid ethnocentrism” One of the big dangers of simulation work is that it produces so much data, so it is natural to just code in some analysis algorithms that spit out digested data. But sometimes this analysis can hide interesting results!

Peter Turchin on Steven Pinker’s “Grand Deception” hypotheses

Posted 26 Jun 2012 / 0

Social Evolution Forum “The ‘Big Mistake’ and ‘Grand Deception’ Hypotheses: Alternatives to CMLS?” These are flaws in Pinker’s arguments that I failed to identify in my own critique, and Turchin prevents some valuable insights. This idea that the human mind can be so easily parasitized or ‘cuckolded’ by ideas is strange, casting ideas and culture as Read More

Steven Pinker makes it clear that he is not a “group selectionist”

Posted 26 Jun 2012 / 5

Frequently I feel like I am listening to an early 2000’s George W. Bush speech when the ‘opponents of group selection’ step up to the podium. Seemingly, you are either “with us or against us” when it comes to considering selection acting at a level above the individual. As someone who is open to thinking Read More

Why Evolution is True “David Sloan Wilson loses it again” This is the guy who is the Past President of the Society for the Study of Evolution, and he just cannot seem to keep his comments focused on science. There are some really great ideas discussed here, particularly about the nature of selfish genes and the Read More
