“Testable claims” is used as a “religious exemption”

The skeptics are circling the wagons. I knew they would. It’s what they always do to defend their naive version of “science”.

Stephanie Zvan has a good post rebutting Daniel Loxton’s defense of the skeptical delusion that atheism is “unscientific”. I can summarize his argument briefly: “I’m an atheist, skeptics have gone after some religious claims, and science can’t tell the difference between invisible dragons and nonexistent dragons and therefore doesn’t care.” And of course he props all this up with the claim that this is the official scientific view.

No, it is not. There is no one true scientific method; testability is not the sole criterion that scientists use to work towards the truth; there is no absolute definition of what constitutes science (nor can there be, I would argue), which is why the demarcation problem is so difficult. Establishment skeptics love to parade their kiddie version of how science works as justification for dismissing atheism as a legitimate scientific position in a way that they would never do to homeopathy or UFOs or any of the other subjects they are willing to pursue. Why, I don’t know. I’ve always assumed it was a political ploy to avoid annoying numerous donors and the mass media, but if they insist it isn’t, I’m going to have to fall back on another explanation: they’re just ignorant.

These skeptics love their little gotcha games. Their ideal is the experiment that, in one session, shoots down a claim cleanly and neatly. So let’s bring in dowsers who claim to be able to detect water flowing underground, set up control pipes and water-filled pipes, run them through their paces, and see if they meet reasonable statistical criteria. That’s science, it works, it effectively addresses an individual’s very specific claim, and I’m not saying that’s wrong; that’s a perfectly legitimate scientific experiment.

I’m saying that’s not the whole operating paradigm of all of science.

I’m saying that we use all kinds of methods: reason, empiricism, inference, hypothesis testing, modeling. Sometimes it conforms neatly to the standard diagram of the scientific method you’ll find in the first chapter of your introductory biology textbook, and often it doesn’t. Science has more avenues to explore questions than just the insta-test skeptics favor, and you should mistrust skeptics who tell you that we know less than we do, because simplistic reasons, like testability.

Individual skeptics may have opinions about all those philosophical matters, but none of these are questions science can answer. As Novella and Bloomberg explained [in a well-known 1999 Skeptical Inquirer article], “science can have only an agnostic view toward untestable hypotheses. A rationalist may argue that maintaining an arbitrary opinion about an untestable hypothesis is irrational—and he may be right. But this is a philosophical argument, not a scientific one.”

Uh, guys? Science is a philosophy, a very specific one. That disavowal doesn’t even make sense.

And you know, I deal with creationists all the time who use arguments very much like skeptics’ to claim that paleontology is untestable and therefore unscientific. “Were you there?” Can you design a simple test that can be demonstrated on a stage to a crowd of onlookers that really shows that that fossil bone is 70 million years old? And the answer is that no, we can’t make our tests conform to the simplistic skeptic standard. That doesn’t mean they’re unscientific, or that we should be agnostic on the age of the earth.

I think this is where the skeptic movement’s foundation in stage magicians begins to hurt. They offer a valuable perspective — they’re far better at detecting intentional fraud than most scientists — but when your whole perspective on science is shaped entirely on criteria that make for a good show, your understanding suffers. And when it leads to stage magicians yelling from the stage at scientists that they don’t understand science, you’ve got a real hubris problem.

You know how real scientists treat untestable hypotheses? Pragmatically and operationally as invalid*. If you don’t even have an evidential chain of reasoning to lead to your hypothesis, we reject it out of hand. If that hypothesis, unsupported by evidence, further contradicts known properties of the universe, we can dismiss it as falsified, even without direct testing of that specific hypothesis…especially if such testing requires elaborate, expensive, time-consuming procedures with negligible likelihood of coming up with a useful result (and if there is no possible way to test your absurd claim, then fuck it, into the trash bin with it). When there are a thousand equally unjustifiable hypotheses being flung about with fanatical certainty and equal lack of reason, we cut the Gordian knot and reject them all and start working our way through known facts to determine a root cause of all the chaos.

I like Stephen Jay Gould’s definition of a fact:

In science, ‘fact’ can only mean ‘confirmed to such a degree that it would be perverse to withhold provisional assent.’ I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms.

By that definition, the non-existence of gods is a fact. Those scientific atheists, the New Atheists, that the skeptics scorn have been working their way down the objective chain of evidence, not trying to disprove gods with simplistic tests (because they’re too incoherent and contradictory), but developing better ideas that more accurately describe how the world works. They’ve been doing the hard work of science. When Victor Stenger can so eloquently describe the natural origin of the universe godlessly using mathematics and physics, when Richard Dawkins can explain the origin and modification of life without recourse to magic or the supernatural, it becomes perverse to withhold provisional assent and babble about being agnostic towards religious explanations. The New Atheists aren’t expressing mere opinions, they’re telling you about hard-earned knowledge about the real world.

And the skeptic movement has become an inbred circle of perversity. They disrespect that hard-working progressive pattern of scientific inquiry because it doesn’t fit neatly into their game-show model of science.

And, as Stephanie points out, they aren’t even consistent about it. Somehow, they insist that we must be agnostic towards religion, while not being so gentle towards alternative medicine, alien astronauts, or moon landing conspiracy theories.

You do realize that the moon landing conspiracy theories are exactly as ridiculous as religion, don’t you? Assertions of insidious agents carrying out elaborate plans, selective and distorted interpretations of the available evidence, avoidance of the actual, substantial evidence that there actually was a natural event…yet no skeptic is getting up and announcing that we must be agnostic about the moon landing, nor are they all beating up Phil Plait for his “unscientific” confidence that men have walked on the moon.


*And even there, there are exceptions: think of string theory. But the exceptions prove the rule that science is a lot more complicated than the neat tidy package into which movement skeptics want to tie it up.

If you want to raise hordes of zebrafish…

…like I do, here’s a useful resource: Regular Care and Maintenance of a Zebrafish (Danio rerio) Laboratory: An Introduction. It’s text and a video guide to familiar procedures.

Unfortunately, it also assumes you have a commercial zebrafish rack, which if you buy the smallest size available, will set you back about $10,000. I’ve just been using an array of 5 gallon tanks, each with its own filter system, which is cheap to set up, but a pain to maintain. I’m going to bite the bullet and build my own DIY flow-through system this summer, though, which I expect will cost a few hundred dollars…which is more in my budget. If you want to follow along, here’s a paper on a Modular, Easy-to-Assemble, Low-Cost Zebrafish Facility — it’ll be something like that. It’s not exactly the kind of show aquarium you’d have in your home, but if all you care about is embryo throughput, it’s loads of fun and lower maintenance than what I’ve been doing so far.

Did a bat land on you at the Kelso Depot in the Mojave Desert?

Boosting signal on this, because it’s potentially very urgent and the person at risk could be anywhere in the world at this point.

A week ago, on April 30, a visitor to the Kelso Depot in the Mojave National Preserve had a bat land on his neck. The bat — a Myotis lucifugus a.k.a. little brown bat — has since tested positive for rabies, and now San Bernardino County officials are trying to find the man. They don’t know if he was bitten or scratched: it wouldn’t take much of a bite to transmit the disease, and if that happened he’s got to get vaxxed.

Details on the incident and public health contact info are here. The guy doesn’t have a lot of slack before getting to the doctor at this point: onset of symptoms can start mere days after a bite. (Or years, which has caused people to falsely assume they’ve dodged a bullet.) Before symptoms start prevention is straightforward and no longer arduous. I’ve had rabies shots and they weren’t the worst injections I had that year. (Individual mileage varies there, but they’re way better than they were back in the day. Mine were a breeze.)

And it’s a good opportunity to remind people in bat and rabies country that while transmission of rabies from bats to humans is quite rare, bats exhibiting unusual behavior (like not being shy or nocturnal) should be given a wide berth and reported to local authorities.

The first day of the rest of my summer!

It’s going to be a good season, I can tell already. It’s finals week, so I’ll still have an abrupt pile of grading to do on Thursday, but otherwise, my teaching obligations are done for the semester. Now I’m trapped, trapped I tell you, in Morris for almost (I do have two quick trips to Europe planned) the entire summer with a collection of administrative responsibilities, but the good part of that is that I have ambitious plans for what I’ll be doing in the lab. I’m also going to be living the good life.

So this morning I slept in to 7:00. I know, it’s slothful of me, but I have the freedom to indulge myself a little bit now and then. After I got up, I took a nice brisk walk downtown, did some shopping, stocked up on some fresh vegetables, and once I got home, chopped them up and set them to soak in a tasty marinade. I’ll roast them up for dinner tonight.

Then I started reading up an accumulated mass of papers that’ll give me some implementation ideas for the work I have planned.

I’ll have a student working with me, and we’ve got a couple of projects in the works.

  1. There’s some boring scut work to be done: lab cleanup, clearing out old reagents from the refrigerator, making up new stock solutions. Don’t be disillusioned, but part of the research life is janitorial…so much dishwashing.

  2. My grand plan requires an expansion of my fish colony to include multiple genetic strains, so we’re going to be scrubbing tanks, sterilizing surfaces, setting up new tanks with boring feeder fish to get the nitrogen cycle going and condition the water, getting the brine shrimp hatchery (live fish food!) thriving, all that sort of stuff that qualifies you to be a clerk in a pet store.

  3. Once all the tanks are bubbling away happily, we’re getting some new strains from the zebrafish stock center. Then it’s a few months of nursing them along, collecting eggs, propagating new generations and raising them to adulthood to get the whole colony self-sustaining, and to prepare for crosses to produce hybrid strains. After all this, my student will be well-trained to be a hobbyist aquarist.

  4. Concurrently, we’ll be doing some real science on the embryos we get, analyzing their behavior quantitatively to identify consistent differences between strains, and also in response to different environmental stresses. This is going to require a bit of computer work and — oh, no! — basic math to develop image analysis protocols. That’s what I’ve been reading about; I’ve done some of this in the past on an obsolete software system, so I’m going to have to piece together some custom bits to make it all work. I’ve been reading about Fourier analysis and power spectra all morning, and I’m kinda jazzed. Math! Computers! Embryos! Science!

  5. The dream is that once we’ve found some subtle differences between different strains, we can start doing crosses to dissect out and isolate the genetic components, if any, of the behavior. That’s going to take a couple of generations of crosses, which means that if I’m lucky we’ll get those results next year, or at worst, the year after. Behavioral Genetics! Yay! Long generation times! Boo!

It’s step #4 that’ll give us some quick quantitative results, I hope, and maybe something presentable at a meeting or even publishable. It’s all going to be preliminary and descriptive, but that’s what you need to do to establish a foundation for experiments.

Unfortunately for you, I won’t be blogging about any of the details of the work this summer — I’ve been scooped before when I foolishly posted protocols on the web, and especially when you have a very small lab with limited humanpower to throw at a problem, that costs. But I might just occasionally say a few general things about the kinds of analyses we’re doing.

Or I could talk about the moldy stuff we throw out of the refrigerator. That’s probably safe.

Mary’s Monday Metazoan: More charismatic megafauna?

Oh, no. The metazoan curator sent me this photo for this time around, and I groaned a bit: more big furries. I told her, “Where are the tubeworms, the crustaceans, the zooplankton? Why no jellyfish or echinoderms?” And she said, “But they’re so cute!” and gave me that look. That look that means I have to do as I’m told.

kangaroo-and-wombat

You know, if she starts sending me cats, I’m just gonna blow up. Me posting cats? That would be one of the signs of the End Times, along with the Last Trump and deluges of blood and whores riding dragons.

What I taught today: FINAL EXAM TIME!

I’m in Arizona, on my way to Orange County, but that doesn’t stop me: I’ve given my students a take home final exam. I wouldn’t want them to be bored over finals week, you know.

1. In the last lecture, I tried to give you a little context, and explained that a dynamic picture of biology would include evolution, ecology, and development, all subdisciplines that deal with change over time. You’re all upper level students; explain to me how developmental biology fits into the perspective on biology that your experience here at UMM has given you so far. Are there pieces you wish our curriculum emphasized more? Why?

2. We’ve spent most of the semester talking about animals — as it currently stands, evo-devo has an unfortunately limited emphasis on metazoans, with an occasional nod to higher plants. Explore a little deeper. What would an evo-devo of fungi, or bacteria, or protists talk about? Is the toolkit we’ve been talking about truly universal? Give me a brief precis of the developmental principles for any other kingdom.

3. Imagine that after you graduate, you find yourself in an unexpected job: you’re working in university press office or as a science journalist. You have to explain scientific research to the public every day. What general principles would guide you? These should be ideas about ethics, effective communication, psychology, etc. in addition to purely scientific concerns. Tell me what standards you’d have to become a great reporter of science.

There. That should make them think.

“Frack” should be the new obscenity

Read this article on fracking and you’ll agree with me. The oil companies have reached new despicable lows in their efforts to poison the air and water.

Like any good little privileged American, my first thought was…is this going on in my back yard? And the answer is no, it’s not, there is no fracking going on in Minnesota. However, we are one of the prime suppliers of industrial silica sand used in fracking, and we’ve got lots of mining going on in the southeastern part of the state. So we’re just enablers of fracking.

All that sand is going next door to allow lots of fracking in North Dakota, though. Sorry, neighbor. I do find it ironic that a state known for its regressive/conservative social policies is happily making a big chunk of its territory uninhabitable, though.
