One of my pet peeves is lousy research, and even worse is lousy-with-intent pseudo-research. The airwaves are filled with fake factoids crowding out real information. I was once tempted to write a post on what it takes to do good survey research, simply because surveys are widely cited and most people probably mistakenly think they […]
Read more...Human activity has led to a considerable loss of species, and more is in the offing. But what is particularly alarming is that the scientists quoted in the Associated Press and on the BBC today see it coming in mere decades. The discovery is that hotter, wetter periods on this planet are associated with a […]
Read more...The Ig Nobel Prize is given annually by the Journal of Improbable Research to “celebrate the unusual, honour the imaginative – and spur people’s interest in science, medicine and technology”. From the BBC, whose favorite award was for the “gay bomb”: 2007 Ig Nobel Winners Medicine – Brain Witcombe, of Gloucestershire Royal NHS Foundation Trust, […]
Read more...The headline above, from Russia Today (“the first 24/7 English-language news channel to present the Russian point of view”) sound like cold fusion to me, but the story is too skeletal to ascertain whether there might be some truth to it: Russian scientists in the Khibinsky Mountains in the Arctic Circle have made an important […]
Read more...You may have heard the saying, “Just because you are paranoid doesn’t mean they aren’t out to get you.” There ought to be a similar formulations for other forms of distress, such as, “Just because you are neurotic doesn’t mean there aren’t good reasons to be worried.” Today the neurotics got affirmation that widely held […]
Read more...I am reading a very useful primer, “Cognitive biases potentially affecting judgment of global risks,” by Eliezer Yudkowsky, one of the contributors to the blog Overcoming Bias (we made use of one of his posts yesterday). He focuses on existential risk, meaning risks to human existence. Since many people would regard an economic collapse as […]
Read more...In case you haven’t come across it yet, I highly recommend the blog Overcoming Bias, where a number of academics write about epistemology. Given how we are bombarded with new factoids, studies, and commentary on a daily basis, it’s helpful to consider the views of those who think about the nature of knowledge and the […]
Read more...As someone with an elderly parent who takes a huge amount of costly medication to treat risk factors like high blood pressure rather than real diseases, I’ve been suspicious that this approach is less effective than claimed. And I have been particularly leery of the enthusiasm for statins (which lower cholesterol) which some cardiologists have […]
Read more...Periodically, the Earth has experienced significant species die-offs. While the so-called K-T extinction, which marked the end of the dinosaur age, has been attributed to an asteroid crash, other declines remain something of a mystery. An article in Science magazine, summarized on its website, recounts a study by researchers from the University of Kansas in […]
Read more...A sad day for therapists, a boon for big Pharma. From Press Esc: MIT biochemists have identified a molecular mechanism behind fear, and successfully cured it in mice, according to an article in the journal Nature Neuroscience. Researchers from MIT’s Picower Institute for Learning and Memory hope that their work could lead to the first […]
Read more...I will let you in on a dirty secret. Appearances to the contrary, this blog isn’t about finance and markets. Its real purpose is to encourage critical thinking, but since I know a wee bit about the financial services industry, I tend to use that as the point of departure. In that vein, it’s important […]
Read more...A Canadian study, “Food Web–Specific Biomagnification of Persistent Organic Pollutants,” published in Science Magazine, identifies a new class of chemicals that pose a potential threat to human health. This conclusion results from a more fundamental insight: the traditional method of looking at bioaccumulation did so by studying marine life. However, air-breathing creatures discharge toxins differently […]
Read more...This article from the Economist, “The long and the short of it,” points to research that finds a strong correlation between paternal and children’s lifespans, and also indicated that children of older parents are longer-lived (counter-intuitive, since they are also subject to more birth defects). However, this work was conducted with a comparatively small sample […]
Read more...The headline in Mark Thoma’s blog is more colorful: “To Reduce Crime, Get the Lead Out.” His post points to a Washington Post story, “Research Links Lead Exposure, Criminal Activity,” in which economist Rick Nevin says lead exposure is the biggest factor behind crime. Now as any statistician will tell you, correlation is not causation, […]
Read more...Most news stories touting the findings of a ten year investigation of organic versus conventionally farmed tomatoes make broader claims (example; CNNMoney “All-natural veggies good for heart“) than the study’s immediate findings, namely that the fruit, when raised organically, has nearly double the level of some key flavinoids (quercetin and kaempferol. Flavinoids have been found […]
