Brain and Behavior

Yesterday, I did a bit of navel gazing about how cranks, quacks, and antivaccinationists have a penchant for attacking skeptics at work in order to try to intimidate them into silence. Reading the post over again, I realize that it came across perhaps more whiny than it should have, but I guess I was just in that sort of mood when I wrote it. One thing that I didn't discuss, though, is how attacks like this have traditionally been a very reliable indication that that I'm on the right track with respect to the quackery being called out. When I write my usual, run-of-the-mill posts about…
What effect does a constant stream of engaging stimuli have on our relationships? On our social structure as a whole? What percentage of our actions is influenced by others, and how does this translate, at some point, into group behavior? Neurobiologists Prof. Alon Chen and Dr. Elad Schneidman of the Weizmann Institute and their team members have been using mice to investigate these questions. Chen and Schneidman approach the group as a network composed of the joint behavior patterns of mice that had had their fur dyed in bright, glow-in-the-dark colors. Among other things, this enables the…
The damaged done by the antivaccine movement is primarily in how it frightens parents out of vaccinating using classic denialist tactics of spreading fear, uncertainty and doubt (FUD). Indeed, as has been pointed out many times before, antivaccinationists are often proud of their success in discouraging parents from vaccinating, with one leader of the antivaccine movement even going to far as to characterize his antivaccine "community, held together with duct tape and bailing wire," as being in the "early to middle stages of bringing the U.S. vaccine program to its knees." Meanwhile, just…
While we've been waiting and waiting for the physicists to get their act together and deliver on Mr Fusion home energy sources and flying cars, the biologists have been making great progress on the kinds of things that turn biologists on. The latest development: growing tiny little human brains in a bucket. Only let's not call them brains…they are cerebral organoids. Hugo Gernsback would be so proud. Here's the latest development. Start with embryonic human stem cells, or induced pluripotent stem cells (cells which you've reset to a kind of embryonic state by using a virus to transfect them…
I've made no secret of my opinion of Jenny McCarthy. To put it mildly, I don't think that much of her, particularly her flaming stupid when it comes to her promotion of dangerous antivaccine nonsense. To her, vaccines are chock full of "toxins" and all sorts of evil humors that will turn your child autistic in a heartbeat if you let those horrible pediatricians inject them "directly into the bloodstream" and in general "steal" your "real" child away from you the way she thinks vaccines "stole" her son Evan away from her. Indeed, among other "achievements," she's written multiple books about…
In science, there's data, and there's interpretation. It's really easy to collect data (usually), but interpretation is the hard part — it requires an understanding of context and theory, and an appreciation of the real complexity of the problem. It's tempting to simplify all your models — the spherical cow problem — but you also have to justify the reduction in complexity to show that it is reasonable. And that's where some papers blow a hole in their foot. This is particularly a problem when the interpretation of the science is used to argue for policy changes. Here's a paper that's a…
SteelyPalooza came off very well, despite high disaster potential. We were, after all, inviting a dozen five-year-olds plus assorted siblings to our house, on a day when Kate and The Pip were out of commission due to coxsackie virus. Everything went smoothly, though: the kids loved the bouncy-bounce, SteelyKid's playset and playhouse, and the six-person tent we set up out back. They're getting close to an age where they can entertain themselves, so I was even able to enjoy snatches of adult conversation during brief lulls in my hosting duties. This was, however, thoroughly exhausting, so…
Here we go again. The "Holy Grail" (well, a "holy grail") of the antivaccine movement is to have a "vaccinated versus unvaccinated" study performed, or, as it's frequently abbreviated a "vaxed verus unvaxed" study. They believe that such a study will confirm their fixed belief that vaccines are the root of nearly all health issues children suffer today, particularly autism and autism spectrum disorders. In particular, they believe that a "vaxed versus unvaxed" study would demonstrate once and for all that vaccines are the cause of the "autism epidemic." Hilariously, a few years back, the…
You might find this hard to believe, but sometimes I find the antivaccine crank blog Age of Autism to be useful. Obviously, I don't find it useful in the same way that its editors think it is useful. Those paragons of the arrogance of ignorance and fetishism of hatred of science-based medicine don't actually teach me anything about vaccines and autism. The torrents of pseudoscience, quackery, conspiracy mongering, and hostility do, however, serve their purpose. They keep my finger on the pulse of the "autism biomed" movement and what the latest "autism biomed" quackery du jour is. It looks…
I previously addressed the criticisms of my criticisms of evolutionary psychology by Jerry Coyne; Now I turn to the criticisms of my criticisms he solicited from Steven Pinker. This is getting a bit convoluted, so let me first state the basics. I dislike evolutionary psychology. Pinker is an advocate for evolutionary psychology. What brought on this back-and-forth was that I was a member of a panel at a science fiction convention that discussed evo psych; I made a few brief comments on my blog that were capsule summaries of my discussion there. In the section below, the paragraphs preceded by…
On July 15 and 16, about two dozen farmworkers paid an unprecedented visit to Capitol Hill to ask Congress, the Environmental Protection Agency (EPA) and the White House to support increased protection from exposure to pesticides. Farmworkers have lobbied Congress before, but this is the first time such a visit focused entirely on pesticide exposure issues, explained Farmworker Justice director of occupational and environmental health, Virginia Ruiz. Farmworkers are asking Congress to support strengthening the EPA’s Worker Protection Standard for pesticides, a regulation that has not been…
I have disturbed and distressed Jerry Coyne, because I have dissed the entire field of evolutionary psychology. I find this very peculiar, because in my field, Jerry Coyne has a reputation for dissing all of evo devo, so it can't possibly be that we're supposed to automatically respect every broad scientific endeavor. There has to be something more to it than just an academic defense of a discipline. And there is, unfortunately. Here's his prelude. I’ve been known for a while as a critic of evolutionary psychology, particularly when it first began as “sociobiology” in the Seventies. At that…
Last year, reported cases of West Nile virus in the United States hit their highest levels in nearly a decade. It's a good reminder to keep protecting yourself from getting bitten, but it also begs the question: Is this just a sign of a much bigger threat? The answer is just as wily as the pesky mosquito. According to recent data published June 28 in CDC's Morbidity and Mortality Weekly Report, the federal public health agency received reports of 5,780 nationally notifiable arboviral disease cases in 2012. (Arboviral diseases are those transmitted by arthropods, such as ticks and mosquitoes…
Breasts are interesting. For starters, people interested in behavioral biology make much of the fact that in many species males have elaborated or exaggerated traits. But they seem to ignore that other than size and a bit of redistribution of muscle mass, males in humans don't. Maybe facial hair is an elaborated trait, possibly a deeper voice, but both of these could be argued to be non-elaborated in males and, rather, altered in females. Meanwhile, human females have a whole bunch of elaborated traits. Breasts are among these traits. There is a good explanation for this we may touch on…
A long, long time ago in a ScienceBlogs far, far away (well, it seems that way anyway, given the halcyon times back then before Pepsigate), Mark Hoofnagle coined the term "crank magnetism." It was a fantastic term used to describe how susceptibility to one form of quackery, pseudoscience, or just plain crankery tended to be associated with other forms of quackery, pseudoscience, or crankery. It explains why so many creationists tend to be into quackery and/or antivaccinationism, why so many 9/11 Truthers also tend to flirt with Holocaust denial or anthropogenic global warming denialists go…
I saw Maria Konnikova's Mastermind on the book lottery stacks at Science Online, and the subtitle "How to Think Like Sherlock Holmes" practically screamed "This is relevant to your interests!" Not only am I writing a book about how to think like a scientist, one of the chapters I have in mind uses mystery novels and the reading thereof as an example of scientific thinking. I didn't score a copy of it at Science Online, but I did pick up the ebook shortly thereafter, and have been working through it during baby bedtimes for the last month or so, a process prolonged significantly by having to…
Last week, the Journal of Pediatrics published a study that did a pretty good job of demolishing a favorite antivaccine trope used to frighten parents. In fact, it's one of the most effective of antivaccine tropes, as evidenced by a large number of parents who are generally pro-vaccine expressing doubts when asked about this particular antivaccine slogan. I'm referring, of course, to the "too many too soon" slogan, in which antivaccinationists try to imply that the current vaccine schedule somehow "overwhelms" an infant's immune system and leads to autism by some unknown and undemonstrated…
There are some days when I know what my topic will be—what it must be. These are times in which the universe gives the very appearance of handing to me my topic for the day on the proverbial silver platter with a giant hand descending from the clouds, pointing at it, and saying, "Blog about this, you idiot!" Usually, it's because a study is released or something happens or a quack writes something that cries out for rebuttal. Whatever it is, it's big and it's unavoidable (for me, at least). This is one of those days. The reason it's one of those days is because just last Friday, as I was…
Skeptically Speaking has this: This week. we’re looking at what science has to say about the origins of selfless – and even self-sacrificing – behavior. We’ll speak to biology professor Lee Alan Dugatkin, about his book The Altruism Equation: Seven Scientists Search for the Origins of Goodness. And we’ll discuss altruism from a neurological perspective, with Duke University Neuroscientist Steve Chang, whose research in monkeys looks at how their brains process and record helpful inclinations. Get the podcast here.
Over at Lapham's Quarterly, John Jeremiah Sullivan has an excellent article on the subject of animal consciousness. Here's the opening: These are stimulating times for anyone interested in questions of animal consciousness. On what seems like a monthly basis, scientific teams announce the results of new experiments, adding to a preponderance of evidence that we’ve been underestimating animal minds, even those of us who have rated them fairly highly. New animal behaviors and capacities are observed in the wild, often involving tool use—or at least object manipulation—the very kinds of…
