The science must bow to the political narrative yet again

Filed under: Americas, Cancon, History, Science — Tags: , , , , , — Nicholas @ 03:00

In Quillette, Bruce Bourque outlines some fascinating archaeological discoveries on Canada’s east coast and how the scientific findings are being actively blocked to avoid offending First Nations people for undermining or even contradicting their beliefs:

One of the major North American archaeological discoveries of the 20th century was made in 1967 by a bulldozer crew preparing a site for a movie theater in the small fishing village of Port au Choix (PAC), on Newfoundland’s Northern Peninsula. It was a vast, 4,000-year-old cemetery created by a complex maritime culture known among researchers as the Maritime Archaic. The graves contained beautifully preserved skeletons covered in a brilliant red powder called red ocher (powdered specular hematite). Buried with the skeletons were many finely crafted artifacts. A few similar ones had previously turned up in earlier field surveys on the island, but no archaeologist had suspected that such a large and magnificent ceremonial site existed in the North American subarctic.

Had the discovery been made only a few years earlier, it is likely that no trained archaeologist would have taken over from the bulldozer crew. But fortunately, Memorial University in St. Johns had just added archaeologist James (“Jim”) Tuck (1940–2019) to its faculty. The American-born scholar set out to explore the cemetery, eventually excavating more than 150 graves spread over three clusters (which he referred to as loci).

[…]

In regard to the Red Paint People, Reich’s lab at Harvard Medical School analyzed material from the Nevin site in Blue Hill, Maine — the only known Red Paint cemetery that is likely ever to produce well-preserved human remains. Reich’s analysis was not confined to mDNA (which, unlike nuclear DNA, is transmitted through the maternal line, and so cannot address paternal ancestry), and focused instead on autosomal DNA (aDNA) found in cell nuclei, thereby adding information on the paternal line. (This addition can be critically important because, as Reich’s lab had demonstrated, a population can be founded by males and females with very different origins.) The Reich team has yet to publish comprehensive results of its Nevin site analysis. But from what I have heard, their work will confirm the existence of genetic discontinuities between the Red Paint People and later populations in the region, much as with Duggan’s work in regard to the Maritime Archaic.

But this is where events took a strange turn: It was when Duggan’s group announced that they’d gained the capacity to analyze aDNA, and made known their plans to apply this technology to the male genome of their Labrador/Newfoundland skeletal sample, that a sense of apprehension seemed to spread through some quarters of the paleogenetic community.

During the summer of 2020, amid the COVID-19 pandemic and Black Lives Matter protests, Duggan’s project went noticeably quiet. I inquired among team members with whom I regularly communicated, but received oblique and evasive responses about the pace of research and publication. Suspecting that this might be related to sensitivities surrounding Indigenous populations (a topic that has consumed Canadian academia in recent years), I contacted Duggan directly, expressing concern that her valuable work might not be published.

[…]

When the Maritime Archaic tradition vanished, it was replaced, as noted earlier, by unrelated Paleoeskimos, an Arctic people who had then recently derived from Siberia. Following their own disappearance, more recently arrived inhabitants migrated from Labrador, these probably being ancestors of the historic Beothuk, who still lived in the region when Europeans arrived. The last surviving Beothuk, a woman named Shanawdithit, died of tuberculosis in 1829. And since that time, there has been no descendant Beothuk community with whom Duggan, or anyone else, could engage in the “discussions and agreements” she’d described to me.

And even if there were, moreover, Duggan’s own research has demonstrated that the Beothuk were not descended from the Maritime Archaic people of Port au Choix. The only community Duggan might be referring to is the (genealogically unrelated) Newfoundland Mi’kmaq community, whose ancestors arrived on Newfoundland from Nova Scotia in the 18th century, several hundred years after the arrival of Europeans.

Seeking the origin of Vitis vinifera, the grape vine used for most wine

Filed under: Europe, History, Middle East, Wine — Tags: , , , — Nicholas @ 03:00

A mailing from Kacaba Vineyards included a link to this Wine Folly article by Madeline Puckette discussing the origins of the grapes we use for the vast majority of table wines:

Where did wine come from? It wasn’t France. Nor was it Italy. Vitis vinifera, also known as “the common wine grape,” has an unexpected homeland! Let’s dive into the origin of wine.

Current evidence suggests wine grapes originated in West Asia.
Map by Wine Folly based on Google Earth imagery.

Where is The True Origin of Wine?

Current evidence suggests that wine originated in West Asia including Caucasus Mountains, Zagros Mountains, Euphrates River Valley, and Southeastern Anatolia. This area spans a large area that includes the modern day nations of Armenia, Azerbaijan, Georgia, northern Iran, and eastern Turkey.

Ancient wine production evidence dates between 6,000 BC and 4,000 BC, and includes an ancient winery site in Armenia, grape residue found in clay jars in Georgia, and signs of grape domestication in eastern Turkey. We still haven’t pin-pointed the specific origin of wine, but we think we know who made it!

The Shulaveri-Shomu people (or “Shulaveri-Shomutepe Culture”) are thought to be the earliest people making wine in this area. This was during the Stone Age (neolithic period) when people used obsidian for tools, raised cattle and pigs, and most importantly, grew grapes.

A significant percentage of psychiatric problems have a genetic component

Filed under: Health, Science — Tags: , , , — Nicholas @ 03:00

This is not an area I’ve heard much discussion about, other than on Scott Alexander‘s blog(s):

“Codon Wheel for translating genetic code from the Wellcome Trust Sanger Institute” by dullhunk is licensed under CC BY 2.0

Most psychiatric disorders are at least partly genetic. Some, like schizophrenia and ADHD, are very genetic, probably 80% plus. This is strange, because having psychiatric disorders seems bad, so you would expect evolution to have eliminated those genes. Researchers looking into this question argue between two hypotheses.

First, a failure. Evolution is imperfect, so some bad genes manage to slip through. This sounds dismissive, but it’s definitely true to some degree. Thousands of different genes contribute to risk for conditions like ADHD and schizophrenia, with each adding only a tiny amount of risk. When a gene is only very slightly bad, it takes evolution millennia to get rid of it, and during those millennia people are getting new very-slightly-bad mutations, so it all balances out at a certain level of bad genes per generation. Those bad genes are sufficient to explain the existing amount of ADHD and schizophrenia; they’re just evolution not working as well as we’d hope.

Second, a tradeoff between two goods. The genes for psychiatric disorders are good in some way. Maybe having some schizophrenia genes (maybe not enough to give you schizophrenia) makes you more creative and raises your inclusive fitness. This keeps schizophrenia risk genes in the population, and sometimes two people with very high level of these genes will mate and their child will have schizophrenia. “Higher creativity” vs. “lower schizophrenia risk” is a tradeoff, and different people are at different points on the tradeoff, and some people will be so far to one end that they will get schizophrenia.

Recent research has pretty heavily favored the failure hypothesis. If you have enough people’s genomes, you can use some complicated math to infer how evolution is affecting different genes. And on most of the schizophrenia risk genes we know about, evolution has been gradually eliminating them in a way that looks like they’re on net harmful — not keeping them around in a way that looks like they have counterbalancing advantages. In the modern day, people with genes for psychiatric disorders tend to have fewer, rather than more children than people without those genes – except in the case of ADHD, which I’m tempted to cynically attribute to them being less likely to remember to use contraception.

Also, a lot of the theories about how psychiatric disorder genes are good suggest that different disorders are good in opposite ways. For example, schizophrenia genes are supposed to give you more artistic creativity, whereas autism genes are supposed to make you more cool-headed and rational. This makes a kind of intuitive sense looking at the symptoms of the disorders. But it turns out that many, many of the genes that cause autism also cause schizophrenia, and vice versa. They seem to be general genes for having mental disorders, with a wide variety of negative effects — which seems like a better match for the first theory where they’re just plain bad news and evolution hasn’t gotten around to eliminating them yet.

QotD: The (as-yet-unfulfilled) promise of “personalized medicine”

Filed under: Health, Quotations, Science — Tags: , , , — Nicholas @ 01:00

A more useful lesson might be skepticism about personalized medicine. Personalized medicine – the idea that I can read your genome and your blood test results and whatever and tell you what antidepressant (or supplement, or form of therapy) is right for you has been a big idea over the past decade. And so far it’s mostly failed. A massively polycausal model would explain why. The average personalized medicine company gives you recommendations based on at most a few things – zinc levels, gut flora balance, etc. If there are dozens or hundreds of things, then you need the full massively polycausal model – which as mentioned before is computationally intractable at least without a lot more work.

(You can still have some personalized medicine. We don’t have to know the causes of depression to treat it. You might be depressed because your grandfather died, but Prozac can still make you feel better. So it’s possible that there’s a simple personalized monocausal way to check who eg responds better to Prozac vs. Lexapro, though the latest evidence isn’t really bullish about this. But this seems different from a true personalized medicine where we determine the root cause of your depression and fix it in a principled way.)

Even if we can’t get much out of this, I think it can be helpful just to ask which factors and sciences are oligocausal vs. massively polycausal. For example, what percent of variability in firm success are economists able to determine? Does most of the variability come from a few big things, like talented CEOs? Or does most of it come from a million tiny unmeasurable causes, like “how often does Lisa in Marketing get her reports in on time”?

Maybe this is really stupid – I’m neither a geneticist or a statistician – but I imagine an alien society where science is centered around polycausal scores. Instead of publishing a paper claiming that lead causes crime, they publish a paper giving the latest polycausal score for predicting crime, and demonstrating that they can make it much more accurate by including lead as a variable. I don’t think you can do this in real life – you would need bigger Big Data than anybody wants to deal with. But like falsifiability and compressability, I think it’s a useful thought experiment to keep in mind when imagining what science should be like.

QotD: “Genetics is interesting as an example of a science that overcame a diseased paradigm”

Filed under: Health, Media, Quotations, Science — Tags: , , , , — Nicholas @ 01:00

This side of the veil, instead of looking for the “gene for intelligence”, we try to find “polygenic scores”. Given a person’s entire genome, what function best predicts their intelligence? The most recent such effort uses over a thousand genes and is able to predict 10% of variability in educational attainment. This isn’t much, but it’s a heck of a lot better than anyone was able to do under the old “dozen genes” model, and it’s getting better every year in the way healthy paradigms are supposed to.

Genetics is interesting as an example of a science that overcame a diseased paradigm. For years, basically all candidate gene studies were fake. “How come we can’t find genes for anything?” was never as popular as “where’s my flying car?” as a symbol of how science never advances in the way we optimistically feel like it should. But it could have been.

And now it works. What lessons can we draw from this, for domains that still seem disappointing and intractable?

Turn-of-the-millennium behavioral genetics was intractable because it was more polycausal than anyone expected. Everything interesting was an excruciating interaction of a thousand different things. You had to know all those things to predict anything at all, so nobody predicted anything and all apparent predictions were fake.

Modern genetics is healthy and functional because it turns out that although genetics isn’t easy, it is simple. Yes, there are three billion base pairs in the human genome. But each of those base pairs is a nice, clean, discrete unit with one of four values. In a way, saying “everything has three billion possible causes” is a mercy; it’s placing an upper bound on how terrible genetics can be. The “secret” of genetics was that there was no “secret”. You just had to drop the optimistic assumption that there was any shortcut other than measuring all three billion different things, and get busy doing the measuring. The field was maximally perverse, but with enough advances in sequencing and computing, even the maximum possible level of perversity turned out to be within the limits of modern computing.

(This is an oversimplification: if it were really maximally perverse, chaos theory would be involved somehow. Maybe a better claim is that it hits the maximum perversity bound in one specific dimension)

QotD: Repressing the facts in genetic research

Filed under: Politics, Quotations, Science — Tags: , , , , — Nicholas @ 01:00

Now, in 2010, cleared-eyed observers are imagining a near-term future scenario that looks like this: (1) we will shortly have genomic-sequence information on hundreds of thousands of human beings from all over the planet, enough to build a detailed map of human genetic variation and a science of behavioral genetics. (2) We will confirm that variant alleles correlate strongly with significant measures of human ability and character, beginning with IQ and quite possibly continuing to distribution of time preference, sociability, docility, and other important traits. (3) We will discover that these same alleles correlate significantly with traditional indicia of race.

In fact, given the state of our present knowledge, I judge all three of these outcomes are near certain. I have previously written about some of the evidence in Racism and Group Differences. The truth is out there; well known to psychometricians, population geneticists and anyone who cares to look, but surrounded by layers of denial. The cant has become thick enough to, for example, create an entire secondary mythology about IQ (e.g., that it’s a meaningless number or the tests for it are racially/culturally biased). It also damages our politics; many people, for example, avert their eyes from the danger posed by Islamism because they fear being tagged as racists. All this repression has been firmly held in place by the justified fear of truly hideous evils – from the color bar through compulsory sterilization of the “inferior” clear up to the smoking chimneys at Treblinka and Dachau. But … if the repressed is about to inevitably return on us, how do we cope?

It’s not going to be easy. I saw this coming in the mid-1990s, and I’m expecting the readjustment to be among the most traumatic issues in 21st-century politics. The problem with repression, on both individual and cultural levels, is that when it breaks down it tends to produce explosions of poorly-controlled emotional energy; the release products are frequently ugly. It takes little imagination to visualize a future 15 or 20 years hence in which the results of behavioral genetics are seized on as effective propaganda by neo-Nazis and other racist demagogues, with the authority of science being bent towards truly appalling consequences.

QotD: Buying “organic” food

… every time I buy “organic”, I feel like I’m sending a reinforcement to several different forms of vicious stupidity, beginning with the term “organic” itself. Duh! Actually, all food is “organic”; the term just means “chemistry based on carbon chains”.

Take “no GMOs” for starters. That’s nonsense; it’s barely even possible. Humans have been genetically modifying since the invention of stockbreeding and agriculture; it’s what we do, and hatred of the accelerated version done in a genomics lab is pure Luddism. It’s vicious nonsense, too; poor third-worlders have already starved because their governments refused food aid that might contain GMOs. And without GMOs it’s more than possible that the new wave of wheat rust, once it really gets going, might condemn billions to death.

Vegan? I’ve long since had it up to here with the tissue of ignorance and sanctimony that is evangelical veganism. Comparing our dentition and digestive tracts with those of cows, chimps, gorillas, and bears tells the story: humans are designed to be unspecialized omnivores, and the whole notion that vegetarianism is “natural” is so much piffle. It’s not even possible except at the near end of 4000 years of GMOing staple crops for higher calorie density, and even now you can’t be a vegan in a really cold climate (like, say, Tibet) because it’ll kill you. In warmer ones, you better be taking carnitine and half a dozen vitamins or you’re going to have micronutrient issues sneak up on you over a period of years.

OK, I give on gluten-free. Some people do have celiac disease; that’s a real need. But “no trans fat”? Pure faddery, or the next thing to it. The evidence indicting trans fats is extremely slim and surrounded by a cloud of food-nannyist hype. I hate helping to keep that sort of balloon inflated with my dollars.

Who could be against “fair trade”? Well, me … because the “fair trade” crowd pressures individual growers to join collectives with “managed” pricing. If you’re betting that this means lazy but politically adept growers with poor resource management and productivity prosper at the expense of more efficient and harder-working ones, you’ve broken the code.

Finally, “pesticide-free”. Do I like toxic chemicals on my food? No … but I also don’t fool myself about what happens when you don’t use them. This ties straight back to the general cluster of issues around factory farming. Without the productivity advantages of pesticides, synthetic fertilizer, and other non-“organic” methods, farm productivity would plummet. Relatively wealthy people like me would cope with reduced availability by paying higher prices, but huge numbers of the world’s poor would starve.

I buy “organic” food because it tastes better and I can, but I feel guilty about reinforcing all the kinds of delusion and superstition and viciousness that are tied up in that label. We simply cannot feed a world population of 6.6 billion without pesticides and factory farming and GMOs and preservatives in most bread; now, and probably forever, “organic” food will remain a luxury good.

Try telling its political partisans that, though. Hyped on their belief in their own virtue, and blissfully ignorant about scale problems, they have already engineered policies that have cost thousands of lives during spot famines. The potential death toll from (especially) anti-GMO policies is three orders of magnitude higher.

And my problem reduces to this: how can I buy the kind of food I want without supporting dangerous delusions?

QotD: The sting in the tail of genetic research

Filed under: History, Quotations, Science — Tags: , , , , — Nicholas @ 01:00

A specter is haunting genetics; the shadow of racialist slavery, eugenics, and Naziism. Western civilization since 1945, traumatized by the horror of the Holocaust, has elevated anti-racism into an unquestionable secular piety. Much good has been accomplished thereby, but like all pieties the worthy results have been accompanied by a great deal of willed repression, denial, and cant. Evidence that racial genetic differences do matter is not actually hard to find; Murray & Herrnstein’s The Bell Curve (1994) included a brave and excellent summation of the science on this point. Consequently, the bien-pensant reaction to that book was hysterical vilification, anathematization of heresy in full cry. Even at the time the lurking fear beneath the hysteria was easy to spot – that the authors might, after all, be right, and must be damned even more intensely because they might be.

Andrew Sullivan on a “genetic case for communism”

Filed under: Books, Education, Politics, Science, USA — Tags: , , , , , — Nicholas @ 03:00

Actually, this isn’t the case Sullivan himself is making, but he’s summarizing a recent book by Fredrik deBoer, The Cult of Smart: How our broken education system perpetuates social injustice:

There aren’t many books out there these days by revolutionary communists who are into the genetics of intelligence. But then there aren’t many writers like Freddie DeBoer. He’s an insistently quirky thinker who has managed to resist the snark, cynicism and moral preening of so many others in his generation — and write from his often-broken heart. And the core of his new book, The Cult of Smart, is a moral case for those with less natural intelligence than others — the ultimate losers in our democratic meritocracy, a system both the mainstream right and left have defended for decades now, and that, DeBoer argues, gives short shrift to far too many.

This isn’t a merely abstract question for him. He has grappled with it directly. As a school teacher he encountered the simple, unavoidable fact that some humans are more academically gifted than others, and there’s nothing much anyone can do about it. He recalls his effort to teach long division to a boy who had managed to come a long way socially (he’d gone from being a hell-raiser to a good student) but who still struggled with something as elemental as long division: “At one point he broke into tears, as he had several times before … I exhaled slowly and felt myself give up, though of course I would never tell him so. I tried to console him, once again, and he said, ‘I just can’t do it.’ And it struck me, with unusual force, that he was right.”

What DeBoer tries to do is explain how our current culture and political system is geared to torment, distress and punish this kid for no fault of his own. “This is the cult of smart,” DeBoer proclaims. “It is the notion that academic value is the only value, and intelligence the only true measure of human worth. It is pernicious, it is cruel, and it must change.” It has become un-American — or perhaps it always was? — to say that an individual has natural limits, that, even with extremely hard work, he won’t always be able to realize his dreams. And this is not because of anything he has done or failed to do — but simply because of his draw in the genetic lottery of life. The very American cult of education is supposed to end this injustice — except that it doesn’t, because it can’t, and its brutal logic actually exposes and entrenches the least defensible inequality of all, the inequality of nature.

This genetic reality — in fact, the very idea of nature existing at all — is currently a taboo topic on the left. In the most ludicrously untrue and yet suffocatingly omnipresent orthodoxy of our time, critical theory leftists insist that everything on earth is entirely socially constructed, that all inequality is a function of “oppressive systems”, and that human nature itself is what John Locke called a “white paper, void of all characters” — the famous blank slate. Freddie begs to differ: “Human behavioral traits, such as IQ, are profoundly shaped by genetic parentage, and this genetic influence plays a larger role in determining human outcomes than the family and home environment.”

People are not just born unequally and unfairly into class, and culture, and place, they are inherently unequal in various ways in their very nature: “not everyone has the same ability to do calculus; not everyone has the same grasp of grammar and mechanics … we can continue to beat our heads against the wall, trying to force an equality that just won’t come. Or we can face facts and start to grapple with a world where everyone simply can’t be made equal.” And this is not a counsel of despair. What Freddie is arguing is that, far from treating genetic inequality as a taboo, the left should actually lean into it to argue for a more radical re-ordering of society. They shouldn’t ignore genetics, or treat it as unmentionable, or go into paroxysms of fear and alarm over “eugenics” whenever the subject comes up. They should accept that inequality is natural, and construct a politics radical enough to counter it.

[…]

This genetic case for communism can leave a reader a little disoriented, I have to say, if only for its novelty. But it is more coherent, it seems to me, than a leftism that assumes that genes are irrelevant to humans and society, that the ultimate goal is to be as smart and thereby wealthy as possible, and that we can set up an educational system where everyone, regardless of their genetic inheritance, can succeed or fail by their own efforts. What sounds like a meritocratic dream is, in practice, a brutal and unforgiving formula for most who can’t achieve it — and has obviously failed if its task is to foster equality. In fact, mass education appears to have increased the gulf between rich and poor. As Freddie notes, “education is not a weapon against inequality; it is an engine of inequality.”

QotD: The first invasion of Britain

Filed under: Britain, History, Quotations, Science — Tags: , , , — Nicholas @ 01:00

Before about 2500 BC, ancient Albion was inhabited largely by farmers tracing back to the Fertile Crescent. Suddenly, steppe barbarians, bearing the Bell Beaker culture, arrived, and almost immediately most of the old Britons died off.

Since then, 90 percent of subsequent skeletons in England reflect the DNA of the steppe invaders.

What happened to most of England’s earlier inhabitants? One of the less violent scenarios is that the steppe migrants introduced bubonic plague.

In general, “migration” and “mixture” tend in Reich’s book to serve as euphemisms for genocide of the native males and rape of the native females. Reich lists numerous examples from around the world where genetic data show that newcomers enslaved or murdered the local men and turned their women into concubines.

Fortunately, for the past 4,500 years, “ancient Britons harbored a blend of ancestries very similar to that of present-day Britons.” The Roman conquest didn’t leave much of a genetic mark, and the later Anglo-Saxon, Danish, and Norman invaders were genetically similar enough to earlier Britons that geneticists have only recently begun to disentangle them.

After 1066, the island race enjoyed a long halcyon era without new invaders raping and pillaging. But all good things evidently have to come to an end. As Benjamin Schwarz has pointed out, “In fact, Britain today receives more immigrants in a single year than it did in the entire period from 1066 to 1950.”

QotD: “[T]he fascinating modern science of high-tech grave robbing”

Filed under: Books, Quotations, Science — Tags: , , , — Nicholas @ 01:00

Since then, an endless stream of anthropologists have assured us that race is just a social construct, that ancient peoples made pots not war, that Aryan conquests in India and Europe were Nazi delusions, that the caste system was imposed on the egalitarian Indians by British colonialists, and many other agreeable suppositions.

As Fitzgerald’s friend Hemingway ended The Sun Also Rises, “Isn’t it pretty to think so?”

But now the brilliant Harvard geneticist David Reich has published a bombshell scientific book, Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past, whose revelations would have been found congenial by a smarter version of Buchanan (such as Fitzgerald himself).

Despite Reich’s occasional need to stop his otherwise lucid narrative to spew irrational rage against his fellow race-science heretics such as James D. Watson, the genome expert conclusively demolishes the post-Boasian anthropologists’ conventional wisdom.

[…]

Reich learned the fascinating modern science of high-tech grave robbing from Svante Pääbo. This Swedish biologist invented the techniques for extracting from ancient skeletons their DNA. (Interestingly, the 1990 Native American Graves Protection and Repatriation Act makes it hard to get hold of ancient American Indian skeletons, but other races’ ancestors appear to be fair game.)

Reich applied to Pääbo’s breakthrough the traditional American knack for vast industrial scale. Assisted by English code-cracker Nick Patterson’s innovations in extracting meaning from bits and pieces of ancient genomes, Reich’s factory-like lab at the Broad Institute has been churning out a tsunami of papers on fascinating questions of prehistory.

QotD: Science, evidence and “cognitive creationism”

I wrote about this problem in one of my Scientific American monthly columns recently, noting that both the Right and the Left distort science in the service of their ideology. On the Right we see the denial of evolution, vaccinations, stem cell research, and global warming. On the Left we see the distortion or denial of GMOs, nuclear power, genetic engineering, and evolutionary psychology, the latter of which I have called “cognitive creationism” for its endorsement of a blank slate model of the mind in which natural selection only operated on humans from the neck down.

What can we do about this problem? First, we must acknowledge that for most issues most conservatives and liberals are pro-science. Recent surveys show that over 90 percent of both Republicans and Democrats in the U.S., for example, agreed that “science and technology give more opportunities” and that “science makes our lives better.” In other words, anti-science attitudes are formed in very narrow cognitive windows — those in which science appears to oppose certain political or religious views. Knowledge of a subject helps a little. For example, those who know more about climate science are slightly more likely to accept that global warming is real and human-caused than those who know less on the subject. But that modest effect is not only erased when political ideology is factored in, it has an opposite effect on one end of the political spectrum. For Republicans, the more knowledge they have about climate science the less likely they are to accept the theory of anthropogenic global warming (while Democrats’ confidence goes up).

In another Scientific American column I wrote about this “backfire” effect, in which the more information you give someone that contradicts a cherished belief, the less likely they are to change their mind; in fact, they double-down on the belief. But this only applies to important political, religious, or ideological beliefs.

If you don’t have a dog in the fight then the facts can change your mind. But the cognitive dissonance created by facts counter to beliefs by which you define yourself will almost always be resolved by spin-doctoring the facts, not by changing your mind. Thus, when I engage in debate or conversation with creationists, for example, I don’t give them the choice between Darwin and Jesus, because I know who’s going to lose that one. Instead, I try to convince them that evolution was God’s way of creation, just like people in Newton’s time and after came to believe that gravity was God’s way of creating solar systems. I don’t believe that myself, of course, but the point is to get people to embrace science, not to win an argument. With climate deniers, I know from research and personal experience that when they hear “global warming” they think “anti-capitalism,” “anti-freedom,” “anti-American way of life.” So I take that off the table by showing them how investing in green technology is going to be one of the most lucrative enterprises in the history of capitalism. I call this the Elon Musk Model.

In any case I don’t think we’re really going to have strange new hybrid species; it’s more likely people will seek some sort of body modification that will make today’s tongue studs look as tame as Hello Kitty temporary tattoos. I’m guessing that young guys will go for the elk horns, which at least would make bar fights more interesting. Young women would opt for a Bambi tail. Gastronomes would shyly ask their doctor if they could get some cow genes — multiple stomach chambers, one for each course! — and geeks would request those agile monkey toes that come in handy when you’re up all night writing viruses. We’ll be shocked at first; they’ll be ostracized. In 2064 a presidential candidate will be forced to withdraw when someone digs up college pictures that show him sporting a scaly tail.
