Turning a blind eye to science
"Newspaper coverage of science outside of health and wellness is steadily eroding. Even here at The Times, where the Science Times section celebrated its 25th anniversary in 2003 and management has always supported strong science coverage, we (like everyone in print media) are doing ever more with less. At CNN, among those leaving will be Peter Dykstra, a seasoned producer focused on science and the environment, and Miles O’Brien, a longtime CNN reporter and former morning news anchor, who I got to know when he turned to climate coverage in a big way several years ago. (See his spicy interview with Senator James Inhofe, the Oklahoma Republican who challenges dire climate projections.)"This is an important time for science in America. More and more we are facing an ideological struggle over the role of science and rationalism in society. In this clip from the "Big Think", Princeton geneticist Bonnie Bassler laments the fact that our culture has become weary, or even fearful of science:
We cannot forget that science is more than simply a collection of facts and figures. Science is a framework for understanding our world, for expanding knowledge and understanding. Science is what allows us to move forward. As Olivia Judson notes, science also provides a level-playing field for sharing ideas:
"...the beauty of the scientific approach is that even when individuals do succumb to bias or partiality, others can correct them using a framework of evidence that everyone broadly agrees on. (Admittedly, this can sometimes be a slow process.) But arguing over data is different from suppressing it. Or changing it. Or ignoring it. For these activities debase the whole enterprise and threaten its credibility. When data can’t be accessed or trusted, when “facts” are actually illusions — well, this threatens the nature of knowledge itself. And a society without knowledge is steering blind. The rubbishing of science is far more serious than any particular decision over whether to fund research into stem cells, the sexual behavior of fruit flies or the quarks and quirks of particle physics. Undoing the damage of the past eight years may take another eight. But it must be done. We are probably one of the last generations that will be able to use our knowledge and methods to guide human civilization to a sustainable future. This is our time."

Forget Lehman Brothers, it's the witches who should be worried
"Emily Oster, an economist at the University of Chicago, has tried to gather systematic data on the link between witch trials and the weather. The results look striking: between 1520 and 1770, colder decades go hand-in-hand with more trials. The link may be simply that witches were often blamed for bad weather. Or there may be a less direct link: people tend to lash out in tough times. There is some evidence, for instance, that lynching was more common in the American south when land prices and cotton prices were depressed.
Such deaths are, sadly, not a historical footnote. In Meatu, Tanzania, half of all reported murders are “witch-killings”. Such murders have been documented elsewhere in Africa, in Bolivia and in rural India. The difference between the historical executions and modern attacks are that a Tanzanian “witch” typically dies at the hands of her own family. The machete is the weapon of choice."
Economists typically assume that individuals are "rational"-- that is, they base their decisions on costs and benefits. Hartford, the author of "The Logic of Life" does a particularly good job of showing the rational basis for even the strangest behaviors.
So why would people target witches during economic downturns? The Tanzania example provides some clues:
"Edward Miguel, an economist at the University of California, Berkeley, and co-author of Economic Gangsters, a book about the economics of crime, corruption and war, has studied the Tanzanian situation. He argues that there is a direct economic motive for the attacks. Tough times in a Tanzanian household may well result in starvation, and the elderly – especially women – are at risk of being sacrificed to free resources.
As evidence, Miguel points out that victims of witch attacks in Meatu district – almost all old women – tend to be from the poorest households. The murders are much more common during years of drought or flood."
The upshot is that understanding the "rational" basis for seemingly crazy behaviors helps us figure out how to solve problems:
"A grass-roots alternative has emerged in another Tanzanian district, Ulanga, where traditional healers “cure” elderly women of witchcraft by shaving their bodies and smearing their pates with “anti-witchcraft paste”. Miguel does not think it’s a coincidence that the healers also provide the women with food and shelter during famines, in expectation of payments from their families in better times. Spiritual ceremony meets social insurance: it is a solution, of sorts."
Individuals may harm others for no apparent reason. But groups usually require some sort of push. Rather than dismissing witch trials as "crazy" of "culture-driven", we can look to see if there is some logical basis for them. As the US sits on the brink of a financial meltdown, we may want to take a few minutes to think about who we might lash out against as times get tough. Any bets?
