A 43% reduction in American childhood obesity has been reported across multiple news outlets, but some question such striking results. Mark Liberman at Language Log has done some digging and suspects both the statistical treatment of reference population growth charts, as well as changes to the sampling method which result in a more racially-inclusive population.

We eat too much of everything… except yogourt: the FDA has proposed new serving sizes for several types of food to better reflect actual consumption habits.

What do women want while ovulating? Positional goods that improve their status compared to that of other women, according to a new paper in the Journal of Marketing Research. “Overall, women’s monthly hormonal fluctuations seem to have a substantial effect on consumer behavior by systematically altering their positional concerns, a finding that has important implications for marketers, consumers, and researchers” [via Marginal Revolution].

“Professors, We Need You!” Nicholas Kristof argues in the New York Times that professors need to make themselves relevant in real-world debates. Professors argued back that they already do, and that they might be better off staying in the (shrinking) ivory tower: for one thing, there are no FBI background checks.

Food research is notorious for flip-flopping, but studies suggest that consumers of whole milk and butter are less likely to be obese. NPR explores this “full fat paradox.”

“These gender differences that everyone knows exist, and they know they’ll always exist and they’re biological — when I started pressing on them I found that a lot of those assumptions hadn’t really been tested.” New York Magazine interviews psychologist Terri Conley, whose work debunks evolutionary explanations for men and women’s sex preferences.

One in four Americans believes that the sun revolves around the Earth, according to the results of a NSF survey presented at the recent AAAS meeting. But according to Time magazine, Europeans fared even worse on that question, with one in three responding incorrectly.

Despite an outpouring of protest and offers of rehousing, Copenhagen Zoo killed its “surplus” male giraffe Marius, and then performed a public autopsy with children in the audience. Meat from the corpse was fed to the zoo’s lions. Marius’ death has sparked discussion on the ethics of zoo conservation, with some blaming the zoo’s actions on Denmark’s pragmatic culture.

The health outcomes of people living in food deserts, areas without access to fresh food and which have prompted healthy eating initiatives, aren’t improved by improving access to fresh food; some researchers even believe food deserts aren’t the issue but that the cumulative stress (allostatic load) caused by long-term poverty is responsible for illness. Nutrition is a confusing field with a “dysfunctional research establishment.” All we know without a doubt is that Americans really love pizza.

A report commissioned by The Beer Store, Ontario’s beer retailer, claims that beer would become more expensive if customers could purchase it at convenience stores. But the author of a previous study commissioned by the Ontario Convenience Store Association disagrees.

Bill Nye, The Science Guy debated Ken Ham, young-Earth creationist and head of the Creation Museum, on the question “Is creation a viable model of origins in today’s modern, scientific era?” The entire debate can be viewed on YouTube. While some in the scientific community welcomed the publicity, others claimed that Nye lost by showing up. Post-debate, creationists provided answers to evolutionist issues raised at the debate, while Buzzfeed collected questions from creationists which have been tackled by quite a few bloggers.

Some sciences are just harder than others: a new study in the  Interdisciplinary Journal on Research and Religion claims that social science professors are more religious and politically extreme than their counterparts in the natural sciences, and that the difference is due to the higher intelligence of the natural scientists, thanks to the correlation of both religiosity and political extremism with lower intelligence.

What should a first-semester, first-year, part-time, mature psychology MA student do upon discovering faulty math in an extremely popular paper in American Psychologist claiming that complex fluid dynamics proves that a ratio of 2.9013 positive to negative emotions is the tipping point for human flourishing? Well, if you’re Nick Brown, you team up with Alan Sokal and psychologist Harris Friedman and publish a takedown in the same journal.

Much has been written about Stephen Hawking’s black hole U-turn, prompted by his submission of a paper to arXiv claiming that “there are no black holes.” But as PopMech points out, Hawking’s quote continues with “—in the sense of regimes from which light can’t escape to infinity. There are, however, apparent horizons which persist for a period of time”: Hawking is weighing in on a debate about event horizons. And to top it off, the Borowitz Report posted a satirical column wherein Michelle Bachman claims that Hawking’s reversal means we shouldn’t believe climate or evolutionary science, which quickly went viral. [via Gizmodo]

Prediction Markets for Science: Preliminary Review and Thoughts

Mike Thicke

Science is often heralded as the pinnacle of rational inquiry: the premier method of acquiring truth about the world, and the standard against which all other methods of investigation should be judged. However, this has not immunized science from charges of irrationality and bias. From Thomas Kuhn and Paul Feyerabend, to sociologists of science such as Barry Barnes and Bruno Latour, to present-day critical “skeptics” of climate science or Darwinian evolution, science seems to be under continual attack as a source of reliable, objective knowledge. Nevertheless, few argue that there is any better option. Current critics of modern Darwinian theory, for instance, do not claim that science has nothing to tell us about human origins, but rather claim that their methodology—intelligent design theory—is the true way of doing science. Similarly, global warming skeptics do not claim that science has nothing to tell us about the Earth’s climate, but rather claim that the purported scientific consensus around global warming is false and that an objective scientific assessment of the evidence does not support the “consensus” position. Debates today are not over whether science should be done, but how it should be done, and who is really doing science (Brown 2009).

It might come as a surprise, then, that there is a rival epistemic system to science that claims not just to avoid science’s vulnerability to ideological bias, but to react to new information both correctly and (nearly) instantaneously. That system is, of course, the market.

This post contains some of my initial research and thoughts on the use of a particular kind of market—the prediction market—within science. For some areas of science that involve widely dispersed knowledge and relatively concrete empirical predictions, such as climate science, prediction markets have many appealing features for improving research practices. They also offer potential alternative structures for funding scientific research. However, there are many reasons to be skeptical of proposals to integrate prediction markets into science. Some of these reasons are linked to the structure of markets in general, while others are specific to prediction markets or prediction markets for scientific facts. A more full discussion of prediction markets and science will form a chapter of my dissertation.

Why do dogs romp in the snow? Because it’s fun, of course!

Acclaimed biologist Lewis Wolpert has apologized for using the unattributed work of published papers, websites, and Wikipedia in his 2011 popular science book on ageing, You’re Looking Very Well, which has now been withdrawn by his publisher Faber & Faber. Wolpert, in his 80s, also included unattributed material in a not-yet-published manuscript, Why Can’t a Woman Be More Like a Man? This case joins other recent high-profile cases including Jane Goodall’s Seeds of Hope (plagiarism) and Jonah Lehrer’s Imagine: How Creativity Works (quote fabrication).

Dick Swaab, a neurobiologist from Amsterdam University, presented controversial results from his new book We Are Our Brains on mothers’ lifestyle choices and infants’ development (including their sexuality and IQ) in an interview with the Sunday Times (paywall-protected; summarized in the Telegraph). Swaab’s description of homosexuality, along with lower IQ and autism, as the result of fetal exposure to toxins, is troubling to some.

Weekly Roundup – Happy New Year Edition

It’s been a big year on the science front, and that means taking stock:

In the face of strong criticism, including a condemnation from the American Association of University Professors, the Kansas Board of Regents has reconsidered its new social media policy for public university professors. The decision made employees’ “improper” posts on social media (defined widely as “any facility for online publication and commentary, including but not limited to blogs, wikis, and social networking sites such as Facebook, LinkedIn, Twitter, Flickr, and YouTube”) a fireable offence. Worryingly, any communication deemed “contrary to the best interest of the university” could fall under this policy, which was prompted by University of Kansas tenured professor David W. Guth’s incendiary anti-NRA tweet in light of the Washington Navy Yard shooting; Guth was temporarily suspended. The decision has led to much debate over professors’ freedom of speech; reflexively, KSU English professor Philip Nel pointed out that even his blogging about the situation could be construed as grounds for termination.
