Dec 20 is the anniversary of the Kitzmiller decision, an early Christmas day present for science and common sense. But when I first wrote here “Judge E. Jones III’s ruling is … unlikely to be challenged unless at some later date the US Supreme Court acquires a creationist majority” I had not foreseen a creationist Vice-President. Take nothing for granted.
Kitzmiller v Dover Area School District, in which judgment was pronounced on 20th December 2005, is the court case that established that Intelligent Design is not science, but a form of religiously motivated creationism, and as such may not be taught in publicly funded schools in the US.This is a shortened version of what I told the students at Texas Academy of Mathematics and Science, University of North Texas’s early admissions programme, whom I was privileged to be teaching at the time of the trial. I have omitted my discussion of the embarrassing Intelligent Design pseudotext, Of Pandas and People, and the even more embarrassing statement that the Dover School Board instructed teachers to read, for reasons of space and because I have discussed them here before. I have tried to avoid rewriting in…

EVOLUTION: What the Fossils Say and why it Matters, Donald R. Prothero (2nd edition)
If you are interested in evolution, get this book. And make sure that your library gets it. And your children’s highschool library. Incidentally, it’s incredible value; list price $35.00/£27.95 from Columbia University Press, with over 400 lavishly illustrated pages.
The book is a comprehensive survey of the fossil record, supplemented at times with other evidence, and framed as one long argument against creationism. It opens with a general discussion of the ideas behind current evolutionary thinking, moves on to a survey of specific topics in (mainly animal) evolution, from the origins of life to the emergence of humanity, and concludes with a brief discussion of the threat that creationism poses to rational thinking. The argument is laid out clearly in the seemingly artless prose of an accomplished writer in love with his subject matter, with plain language explanations that presume no prior knowledge, while the detailed discussions of specific topics give enough detail to be of value, I would imagine, even to a professional in the field. The author is an experienced educator and researcher, with thirty books ranging from the highly technical to the popular, some 300 research papers, and numerous public appearances to his credit, and the work is copiously illustrated with photos, diagrams, and drawings by the author’s colleague, Carl Buell. These illustrations are an integral part of the work, graphically displaying the richness of the data at the heart of the argument. Read the rest of this entry
I learnt about this pledge from the Skeptic Reading Room. And while I generally loathe public pledges (too much virtue signalling for my liking), I am making an exception for this one, in response to our exceptional times. And the fine print makes admirable reading. Besides, several hundred public figures and organizations have signed it, including Steven Pinker and Peter Singer, and what’s good enough for them is good enough for me. Many dozens of politicians have signed it as well, and one of the aims is to persuade more to do so, and hold them accountable.
Truth matters. Propagating untruth is big business and big politics. The traditional guardians of truth have abdicated, are compromised, or lack traction. By default, the job of protecting truth falls to us. We need to take our responsibility seriously.
We are all drawn towards confirmation bias, group think (our own group, of course!), lack of diligence in verifying material that agrees with us, lack of charity towards opponents, and more besides. So the pledge is no trivial commitment and I certainly found that reading it gave me much pause for thought about my own behaviour.
Here’s what the pledge commits you to. You can sign it here. I have. Hold me to it.
I Pledge My Earnest Efforts To:
- Verify: fact-check information to confirm it is true before accepting and sharing it
- Balance: share the whole truth, even if some aspects do not support my opinion
- Cite: share my sources so that others can verify my information
- Clarify: distinguish between my opinion and the facts
- Acknowledge: acknowledge when others share true information, even when we disagree otherwise
- Reevaluate: reevaluate if my information is challenged, retract it if I cannot verify it
- Defend: defend others when they come under attack for sharing true information, even when we disagree otherwise
- Align: align my opinions and my actions with true information
- Fix: ask people to retract information that reliable sources have disproved even if they are my allies
- Educate: compassionately inform those around me to stop using unreliable sources even if these sources support my opinion
- Defer: recognize the opinions of experts as more likely to be accurate when the facts are disputed
- Celebrate: celebrate those who retract incorrect statements and update their beliefs toward the truth
Yes, Bishop Wilberforce really did ask TH Huxley, “Darwin’s bulldog”, whether he would prefer an ape for his grandfather, and a woman for his grandmother, or a man for his grandfather, and an ape for his grandmother. And Huxley really did say that he would prefer this to descent from a man conspicuous for his talents and eloquence, but who misused his gifts to ridicule science and obscure the light of truth. This and more at the very first public debate regarding Darwin’s work on evolution, only months after the publication of On the Origin of Species.
The debate took place at the May 1860 meeting of the British Association for the Advancement of Science. The actual exchange is whitewashed out of the account of the meeting in the gentlemanly Athenaeum, leading some historians to wonder whether it really occurred, but a recently rediscovered contemporary account places the matter beyond doubt. What I find even more interesting, however, is the way in which argument and counter-argument between Wilberforce and Huxley, and between other supporters and opponents of the concept of evolution, prefigure arguments still being used today.

—Professor HUXLEY, being called upon by the chairman, declined entering into the subject, alleging the undesirability of contesting a scientific subject involving nice shades of idea before a general audience, who could not be supposed to judge upon its merits.
The discussion was then commenced by the Rev. R. GRESWELL, who denied Read the rest of this entry
I cannot improve on this excellent survey, with its refutation of the creationist’s crucial denial that evolution generates new functional information; the most I can do is help publicise it.

The Grumpy Geophysicist is too kind. “It is hard not to look at these actions and them as ostrich-like in trying to avoid hearing things you don’t want to hear.” No; the target is not what they get to hear, so much as what we get to hear. they just don’t want scientific advances that generate news stories about inconvenient facts like global warming or pollution
Some time ago, GG suggested that what many were taking as a “war on science” was more a war on particular parts of science, that the offenders were in fact exploiting science where it was financially remunerative and opposing it where it wasn’t. But actions at the Environmental Protection Agency really look like outright war on science, period.
Consider these actions:
- Reconstituting science panels to only have “committee members [who] will be financially independent from the agency.” Um, so experts who are interested in pollution and are supported by…who is left? maybe industry? If this isn’t the fox watching the henhouse, GG doesn’t know what is. Why would the EPA not use the science that it has paid for, or trust the scientists that it funded? EPA grants are to determine if…

“With every ‘I told you so’ and demand that they apologize to you, personally, for the sin of being wrong, you are hardening [them] against the possibility of changing their minds. I know you may feel that you cannot be happy until they apologize, admit they were wrong, that they were stupid, that everything they ever believed about the war was in error. They know it too… [But] they don’t want to make you happy. Frankly, you haven’t given them any reason to.” Megan McArdle, The Atlantic, writing in 2008, about why so many people still refused to admit that the 2003 invasion of Iraq had led to disaster, and even persisted in believing in the face of the evidence that Saddam Hussein really had had weapons of mass destruction.
Now think how this applies to Trump supporters, as they get more and more opportunities to see what was really meant by “getting rid of Obamacare” or by “cutting taxes” or by “draining the swamp” or by “Make America Great Again”, or by “crooked” or by having someone of Trump’s moral and intellectual calibre in the White House.
Of course, with a little bit of effort you can do even worse than that. You can insult them. Ignore that many of them had voted for Obama (see map on right). Ignore the long slow steady slide of Democratic support in Middle America. Ignore how six decades of business as usual had done nothing or less than nothing for small town rural America. Ignore the loss of American (and other!) lives in undeclared wars that most Americans hadn’t even heard of. Ignore that the alternative to Trump was someone who saw nothing wrong in taking six-figure speaking fees from Goldman Sachs (“that’s what they offered“). Just remind them how stupid you think they are. Call them bigots too, if you like. Or deplorables. Works every time.
The McArdle quotation is from a long and thoughtful essay entitled Anger Management, on the importance of bridge-building, originally written during Iraq’s descent into chaos, but now more relevant than ever. I came across it through Being Wrong, Kathryn Schultz’s splendid account of how we are all more or less wrong (even you and me, dear reader) most of the time, how essential this is to our growth, and how difficult it is for all of us to admit it. Especially when the Other Lot are self-righteously asking us to do so.
A final quote from McArdle: “I as well as anyone know the delights of unloading one’s accumulated venom on richly deserving targets… But I also understand that unloading, while making me feel better, does not usually advance my cause.”
Venom is not, and should not be, enough to win elections.
Rocks! -a brief illustrated primer. A superb, richly illustrated, survey from geologictimepics with detailed inks to an extensive gallery of rock types and formations. And,of course, incidentally proof of the absurdity of Young Earth “geology”

Seems like most people I know like rocks. They bring home unusual rocks from vacations; they admire beautiful facing stones on buildings; they frequently ask “What is this rock”? Considering that the type of rock you’re looking at reflects the processes that caused it to form, some basic rock identification skills can go a long way to understanding our planet!
Of course there are thousands of different rock types —But! they ALL fit into one of three categories: igneous, sedimentary, or metamorphic. Here’s a brief, illustrated summary of each.
Igneous rocks are those that form by cooling and crystallization from a molten state. Consequently, they consist of crystals of various minerals that form an interlocking mosaic like the rock in…
