Can “muppet theory” help explain behavioral heterogeneity in human social groups?

Posted 16 Jun 2012 / 0

National Public Radio “Explaining Muppet Theory: Are You An Ernie Or A Bert?” I have to admit that I am an “order Muppet”, but I also believe that human societies function in part because of their heterogeneity: we need the optimal mix of different behavioral types in order to realize the full potential of our Read More

Posted 15 Jun 2012 / 0

Social Bat “Why vampire bats are a good experimental model of cooperation: natural, cognitive, and controllable” I particularly like Gerry’s two-dimensional space representing different systems on the basis of their complexity and natural-ness!

NY Times provides perspective on E.O. Wilson’s “The Social Conquest of Earth”

Posted 13 Jun 2012 / 0

The New York Times “Lessons from Ants to Grasp Humanity” Funny how the media likes to trot out Jerry Coyne whenever someone questions Darwinian orthodoxy. I cannot entirely blame Coyne for how he is quoted, but his quotes never seem to offer much a substantial critique. The bit on religion is interesting here: Wilson seems Read More

Richard Dawkins on E.O. Wilson’s “The Social Conquest of Earth”

Posted 12 Jun 2012 / 0

Prospect Magazine “The descent of Edward Wilson” First comment on this: what’s up with the ad hominem attacks on Wilson implying (not-so-subtly) that he is somehow slipping (look here for another example) in his old age? Given the massive departure that Dawkins has made from science in his writings on religion, he is the last one Read More

David Sloan Wilson on Richard Dawkins on E.O. Wilson

Posted 12 Jun 2012 / 0

The Huffington Post David Sloan Wilson blog “Richard Dawkins, Edward O. Wilson, and the Consensus of the Many” This is a very clear articulation of the history of multilevel selection. If only all biologists (in particular those who do not work in areas investigating altruistic behavior) could be compelled to read this; a lot of Read More

Don’t mistake having a better map for knowing where you are: new technology for sequencing fetal DNA will not lead to serious trait selection

Posted 07 Jun 2012 / 0

The Takeaway “New Developments in DNA Sequencing” The problem with this kind of story is that it confuses listeners. While it may be a technological advance to be able to perform complete genetic sequencing of a fetus without risky invasive procedures, this new ability does not necessarily lead to the kind of “baby selection” that Read More

Joseph E. Stiglitz discusses the economically destabilizing impact of rent-seeking

Posted 06 Jun 2012 / 0

WNYC The Leonard Lopate Show “Joseph Stiglitz Explains the Price of Inequality” As I have suggested before [1, 2], in order to stabilize our economy, we have to incentivize the generation of income from actual labor — not simply owning resources.
