What do we know about Cultural Transmission?

Posted 29 Jan 2016 / 0

As I have been working on my book-in-progress (Breeders, Propagators, & Creators), I have encountered a difficult-to-answer question of road-block proportions: how do we quantify cultural transmission? The focus of my book is the tradeoff humans face between making babies, spreading existing culture, and inventing new ideas. If such a tradeoff exists, we need to be able Read More

How do we know when people are actually happy?

Posted 15 Jan 2016 / 0

Image courtesy of Wikimedia Commons Science “Conservatives report, but liberals display, greater happiness” This paper was published back in March, but I just discovered it. I am somewhat fascinated by psychological studies of happiness, because happiness is so hard to pin down. What is happiness, and can we rely on people to accurately report how Read More

Is there a trade-off between reproduction and creativity?

Posted 12 Jan 2016 / 0

One of the ideas that I am exploring in my work-in-progress book Breeders, Propagators, & Creators is that human beings face a fundamental trade-off between three activities: Breeding: behaviors that lead to the production of offpsring (which might — but does not necessarily — include parenting); Propagating: behaviors that spread existing cultural ideas; and Creating: behaviors that introduce Read More

Injury intuition confirmation bias? Farce article goes really viral

Posted 12 Jan 2016 / 0

Hurt Apple image by Nina Matthews courtesy of Wikimedia Commons Although of course I would never sanction such behavior, it appears that a farcical medical research article has gone virally awry. The article, Maternal kisses are not effective in alleviating minor childhood injuries (boo-boos): a randomized, controlled and blinded study, was published in late December. Read More

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

How the built environment influences our ability to sustain personal and environmental commitments

“exercise is good in principle, but it’s almost never the case that it’s the best thing you could do right now.” -Dan Ariely There’s a really interesting experiment being conducted by behavioral economist Dan Ariely and the new WNYC program Only Human. Called “Stick to It!“, the experiment allows listeners to the show to volunteer to download Read More

Personalized DNA tests likely to provide further evidence of human inter-connectedness

Posted 06 Jan 2016 / 0

Great NPR piece here on how new technologies in personalized DNA testing have the potential to broadly expand our understanding of human relatedness. I am particularly interested in the idea that these tests further reinforce previous research showing just how much of our gene pool is shared globally rather than locally. While these tests are Read More

My personal experience that creationists gravitate to anything with even the faintest scent of scientific uncertainty (and what to do about it)

Posted 22 Dec 2015 / 0

Last month, I published a rather long review of William Provine’s last book, The “Random Genetic Drift” Fallacy. The book is pretty obscure and I knew that a lot of other evolutionary biologists had dismissed the book as being a bit on the crazy side, so in the back of my mind I was wondering whether Read More

Is family-linked terrorism a cultural and genetic phenomenon?

Posted 03 Dec 2015 / 0

National Public Radio “In Worst Attacks, Terrorists Often Have Fraternal Bonds” This is an interesting — albeit brief — piece on a recent “pattern” that has emerged in terror attacks: teams of attackers are often composed of blood relatives. As a good scientist I have to point out that there’s a danger here of over-generalizing Read More
