Would a “labor economy” lead to different outcomes than the “capital economy”?

Posted 11 Jan 2016 / 0

Evonomics “A Simple Way to Decrease Income Inequality” I am intrigued by the idea that measurements of economic success impact our economic decisions and therefore our economic outcomes. A persistent obsession with capital has created an economic system that responds to capital. But what if employment condition — “labor” — was the fundamental unit of Read More

Clever study shows how cooperative bacteria sanction — and therefore exclude — cheaters

Posted 08 Jan 2016 / 0

ScienceDaily “Cooperating bacteria isolate cheaters” This kind of study is where the field exploring how cooperation evolves should be headed: model predictions are verified by actual microbial microcosms, but the interactions of those microcosms are manipulated by genetically-engineering variation in behavior (what this article calls “synthetic ecology”). This approach helps overcome a common problem faced Read More

Can understanding cooperation lead to higher-yield crops?

Posted 07 Jan 2016 / 0

The Scientist “The Evolution of Cooperation” Starting with the title, this short article is not bringing anything all that new to the existing literature on how cooperation evolves. But once I realized that this piece was really about the direction of Denison’s research on rhizobia, the rest of the basic background made a lot more Read More

How much impact can a set of free game theory infographics have?

Posted 02 Dec 2015 / 0

A few years ago, I worked with graphic designer Greg Riestenberg to come up with a series of infographic images designed to make several foundational game theory constructs easier to understand. Our approach was to take all the numbers out of the representations, using information design to highlight how the games work and how they differ from each Read More

Crucial climate talks in Paris take place in a socially repressive environment

Posted 30 Nov 2015 / 0

At Paris, two equally-nihilistic cultures clash, but where do the people get a seat at the table? Today crucial climate talks are under way in Paris, France amid massive police presence and an atmosphere of social repression. The message is to “stay off the streets” as the leaders of world (and a few monarchs and businesspeople) meet Read More

Religious children are less altruistic… or maybe not…

Posted 16 Nov 2015 / 0

Image courtesy of Wikimedia Commons A recent study published in Current Biology claims to have demonstrated that children raised in religious households are less altruistic and more vindictive than their peers raised in non-religious households. Using two different tests — a Dictator Game conducted with stickers and a task that measured reactions to watching interpersonal Read More

Maybe infants don’t really care who helps and who hinders after all…

Posted 16 Nov 2015 / 0

PLoS ONE “Probing the Strength of Infants’ Preference for Helpers over Hinderers: Two Replication Attempts of Hamlin and Wynn (2011)” Great example of how studies need to be replicated! I am wondering if funding agencies should reserve particular lines for replication studies. Does this kind of funding opportunity exist?

Fascinating and clever study of how personal contact norms vary by relationship

Posted 10 Nov 2015 / 0

Image from PNAS Proceedings of the National Academy of Sciences “Topography of social touching depends on emotional bonds between humans” (Suvilehto et al. 2015) This is a really clever study in that it aggregates a lot of data that is collected rather efficiently from a lot of participants. This makes the results robust for this Read More

Jonathan Haidt on the business advantage of being ethical

Posted 10 Nov 2015 / 0

This is a fascinating talk by Jonathan Haidt, a psychologist situated within one of the most prestigious business schools in the world whose research focuses on morality and emotion. I can’t help but be impressed when someone addressing business concerns leads with biology, and Haidt does a good job of summarizing the “disruptive cooperation” (read: competitively-superior Read More

That beard and deep voice may be to put him in his place, not attract her

Posted 09 Nov 2015 / 0

There have been a lot of evolutionary psychology experiments that have tried to define both female and male attractiveness to the opposite sex, an indirect way to get at the nature of sexual selection in humans. A new study published in Behavioral Ecology reminds us that sexual selection is not the only process that has Read More
