Image source: FlickrMany ecological systems have tipping points - thresholds where small changes in impacts can have very large effects on on ecosystem functioning, often in a bad way. Lakes, for example, might show little impact from nutrient pollution until a threshold level is reached, and then massive algal blooms form that choke off many other species growth.
In the absence of knowledge of exactly how far one can push a system before reaching a tipping point, many invoke the precautio........ Read more »

In the year AD 1098 a spruce tree was chopped down in the Chuska Mountains, which run roughly along what is now the border between Arizona and New Mexico. We don’t know who cut it down, exactly, since the people living in the area at the time had no system of writing and have therefore [...]... Read more »
Since Thorstein Veblen’s 1899 book Theory of the Leisure Class, the economics profession has taken a somewhat mixed approach to consumption. In areas such signalling theory, Veblen’s argument that conspicuous consumption must be wasteful and expensive to be a reliable signal of wealth is well recognised. Conspicuous consumption has a purpose as a signal. However, [...]... Read more »

A recent NPR radio show covered the research of the biosemiotician Con Slobodchikoff of the Univeristy of Arizone on prairie dog calls. The piece is very public-orientated, but still might be worth listening to.

This is a pretty amazing yet simple and straightforward tool.

So, on to the paper by Robert Rowthorn, which I see now has even been picked up by the Denver Post!
Just to explain a bit of the background. Rowthorn is an economist, and his paper is basically a model of what would would happen if you have a gene (strictly speaking [and for Bjørn's benefit], an allele) that predisposes for membership of a group, and if that group has high reproduction.
What he shows is that the gene spreads incredibly quickly - just 10 generations after it appears, 80% of t........ Read more »

Long time readers know well my fascination with quantitative history. In particular, cliometrics and cliodynamics.

A couple of sentences in one of The Economist’s celebrated Christmas articles brought me up short.

Psychopaths are impaired in social exchange and precautionary reasoning From Pychological Science Psychopaths persistently violate social, moral, and legal norms, cheating family, friends, and strangers alike.

By: Dr. Ken Broda-Bahm - So, a retired Brazilian judge, two American litigators, and three German engineers walk into a bar... Okay, so it wasn't a bar, it was an international arbitration, but the potential for miscommunication is just as great as the joke intro would imply. This one took place in Sao Paulo, Brazil and it was preceded by a two-day mock arbitration that I facilitated in order to help our litigation team prepare the best arbitration case possible.

Does the old saying fake it old you make it hold any water? Turns out maybe. Researchers from Columbia and Harvard Universities posed subjects in one of four positions: two high power positions(expansive, open limbs) and two low power positions(contractive, closed limbs). Then they measured risk taking, self-response about feelings, and testosterone and cortisol.The high power positions were sitting stretched in a chair with legs propped up on a table and arms behind the head as well as lea........

If you have ever had the pleasure of being in a boisterous Tokyo bar at night, eating and drinking amongst a din that would sear the armour off a tank,you get the feeling that this is what pure, hedonistic joy must be like. And, according to this article by Ikeda et al. (2011), Japanese men love it as well. The downer seems to be that while all that upbeat male bonding is good for lowering stress, the accompanying fat and alcohol brings on health effects of a less favourable kind.... Read more »

At the end of the 1990s, cognitive psychologist Steven Pinker infamously characterized music as “auditory cheesecake”: a delightful dessert but, from an evolutionary perspective, no more than a by-product of language. But Pinker was probably right when he wrote: “I suspect music is auditory cheesecake, an exquisite confection crafted to tickle the sensitive spots of...our mental faculties.” Or, to express his idea less graphically: music affects our brains at specific places, thereby sti........

She was clearly upset. The disgust on her face was apparent. As was her frustration when she shook her head at the man standing numbly beside her and said, "You have the emotional depth of a turnip!" The rest of us in the subway car did our best to look busy—headphones were put on, games were played on cell phones, even the morning newspaper made a few reappearances even though it was the evening rush hour.
