“…the Venn diagram circles of ‘scientists’ and ‘Lord of the Rings fans’ have a large overlap”

Filed under: Books, Science, Technology — Tags: , — Nicholas @ 03:00

In The Atlantic, Julie Beck wonders “What has it got in its academic journals, precious?”

Though at first glance, science and fantasy seem to be polar opposites, the Venn diagram circles of “scientists” and “Lord of the Rings fans” have a large overlap. One could (lovingly!) label that region “nerds.”

Fight me on that if you want, but there’s plenty of evidence that suggests scientists love J.R.R. Tolkien’s epic. Several newly discovered animal species have been named after characters from the books — a genus of wasps in New Zealand is now called Shireplitis, with species S. bilboi, S. frodoi, S. meriadoci, S. peregrini, S. samwisei and S. tolkieni. The wasps bear the names of the hobbits because they too are “small, short, and stout,” according to a press release. On the other side of the size spectrum, paleontologists named a 900-pound ancient crocodile Anthracosuchus balrogus, after the Balrog, a giant whip-wielding fire monster from The Lord of the Rings. There is also a dinosaur named after Sauron, which seems kinda harsh to me. And many, many more, if the website “Curious Taxonomy” is to be believed.

“Given Tolkien’s passion for nomenclature, his coinage, over decades, of enormous numbers of euphonious names — not to mention scientists’ fondness for Tolkien — it is perhaps inevitable that Tolkien has been accorded formal taxonomic commemoration like no other author,” writes Henry Gee in his book The Science of Middle Earth.

QotD: The barbarians in our midst

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

… possibly the most dangerous barbarians live in the West. These, by being born there, assume they are Westerners by inheritance or osmosis. They also regard Western civilization as “found”, its goodies a stash waiting to be used or distributed. Nor do they trouble themselves as to its provenance, for there has always been plenty more where the stash came from.

For these barbarians Western civilization and its associated quest for God or Truth are a bothersome impediment, a “white man’s culture”, a hundred year old relic ideology nobody bothers with, some irksomely judgmental superfluity that gets in the way of fun and spreading the fruits to arrivals at the border and various victim groups.

For the barbarian the only reality is appearances. Cargo cultists, for instance, believe that function comes from form. If they build something which resembles an airport then gift giving airplanes will arrive there to bring goodies. The 21st century barbarian completely lacks the attitude of Roger Bacon, who lived in the 13th century. Bacon knew that the truth was not a “white man’s” culture — in fact in his day nearly all learning came from the East — but believed the truth was nature’s culture; baked into reality; another word for what used to be called God. Of barbarian ignorance Bacon wrote:

    Many secrets of art and nature are thought by the unlearned to be magical. … The empire of man over things depends wholly on the arts and sciences. For we cannot command nature except by obeying her.

In today’s post-Western environment, we’ve forgotten Bacon’s adage.

QotD: “Science needs women”

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

Science does not need women any more than it needs foot fetishists, pole-vaulters, or Somalis. What science needs (if an abstraction such as science can be said to need anything) is scientists. If they happen also to be foot fetishists, pole-vaulters, or Somalis, so be it: but no one in his right mind would go to any lengths to recruit for his laboratory foot fetishists, pole-vaulters, or Somalis for those characteristics alone.

[…]

It is true, of course, that women are demographically underrepresented in the ranks of scientists, but so are many other groups. (This means, of course, that others are overrepresented.) This may be for more than one reason: lack of aptitude or interest, for example, or deliberate or subtle obstructiveness. But historical attempts to recruit scientists according to some demographic criterion or other have not been met with success, even as far as the advancement of science itself is concerned, and have been made by the very worst dictatorships that in other respects have been abominable. Social engineering and engineering are two very different activities. It would be no consolation to know while on a collapsing bridge and about to plunge into the deep ravine below that it had been built by a truly representative sample of the population, and was therefore a monument to social justice.

Suppose that, instead of Science needs women, other slogans based upon exactly the same logic hung over the arrivals hall: Heavyweight boxing needs Malays, for example, Football needs dwarf goalkeepers, Quantity surveying needs bisexuals, Lavatory cleaning needs left-handers: the absurdity of the argument would be immediately apparent. In fact the categorization both of human activities and humans themselves being almost infinite, the obsession with demographic representation as the most important criterion of fairness or social justice is virtually without end. The search for social fairness in this sense can lead only to perpetual conflict, much as the imposition of parliamentary democracy has done in countries in which it is not an organic outgrowth of their history, and as a true parliamentary regime in the European Union would very soon do.

Charles Stross – “Vampires are not sexy. At least, not in the real world.”

Filed under: Books, Media, Science — Tags: , , — Nicholas @ 02:00

He’s quite right … and he drives home the point in a recent blog post:

Desmodus rotundis isn’t sexy. (Except insofar as small furry rodents that carry rabies aren’t as un-sexy as some other obligate haemophages.) Bed bugs are really not sexy. But if you want maximally not-sexy, it’s hard to top Placobdelloides jaegerskioeldi, the Hippo Arse Leech.

The Hippo Arse Leech is a leech; it sucks blood. Like most leeches, its mouth parts aren’t really up to drilling through the armour-tough skin of a hippopotamus, so it seeks out an exposed surface with a much more porous barrier separating it from the juicy red stuff: the lining of the hippo rectum. When arse leeches find somewhere to feed, in due course happy fun times ensue — for hermaphrodite values of happy fun times that involve traumatic insemination. Once pregnant, the leeches allow themselves to be expelled by the hippo (it’s noteworthy that hippopotami spin their tails when they defecate, to sling the crap as far away as possible — possibly because the leeches itch — we’re into self-propelled-hemorrhoids-with-teeth territory here), whereupon in the due fullness of time they find another hippo, force their way through it’s arse crack, and find somewhere to chow down. Oh, did I mention that this delightful critter nurtures its young? Yep, the mother feeds her brood until they’re mature enough to find a hippo of their own. (Guess what she feeds them with.)

Here ‘s a video by Mark Siddall, professor of invertebrate zoology at the American Natural History Museum, a noted expert on leeches, describing how he discovered P. Jaegerskioeldi, just in case you think I’m making this up.

By the end of my description Jim and Freda were both … well, I wish I’d thought to photograph their faces for posterity. So were the audience. And that’s when I got to the money shot: the thing about fictional vampires is, vampires are only sexy when they’re anthropomorphic.

A revolutionary fix for California’s water problems – pricing

Filed under: Economics, Environment, USA — Tags: , — Nicholas @ 02:00

Last month, Megan McArdle pointed out that the state of California is reacting to the water shortages in one of the least effective ways by mandating rationing, rather than addressing the absurd under-pricing of the resource:

I’ve seen a lot of apocalyptic writing about California only having a year of water left (not true), and I’ve heard some idle talk about whether California can continue to grow. But California’s problem is not that it doesn’t have enough water to support its population. Rather, the problem is that its population uses more water than it has to. And the reason people do this is that water in California is seriously underpriced, as Marginal Revolution‘s Alex Tabarrok notes. While the new emergency rules do include provisions for local utilities to raise rates, that would still leave water in the state ludicrously mispriced. According to Tabarrok, the average household in San Diego pays less than 80 cents a day for the 150 gallons of water it uses. This is less than my two-person household pays for considerably less water usage, in an area where rainfall is so plentiful that the neighborhood next door to me has a recurrent flooding problem.

Artificially cheap water encourages people to install lush, green lawns that need lots of watering instead of native plants more appropriate to the local climate. It means they don’t even look for information about the water efficiency of their fixtures and appliances. They take long showers and let the tap run while they’re on the phone with Mom. In a thousand ways, it creates demand far in excess of supply.

Having artificially goosed demand, the government then tries to curb it by mandating efficiency levels and outlawing water-hogging landscaping. Unfortunately, this doesn’t work nearly as well as pricing water properly, then letting people figure out how they want to conserve it. For one thing, you can only affect large and visible targets, such as appliance manufacturers or lawns. For another, people will often try to evade your regulations — my low-flow showerhead came with handy instructions on how to remove the flow restrictor. And, perhaps most important, you limit the potential conservation to the caps. So people have an efficient dishwasher but don’t consider doing small loads by hand; they have a low-flow showerhead but don’t consider taking shorter showers. In short, no one is looking for ways to conserve more than whatever you’ve mandated. This may be enough to temporarily manage the current crisis, but it does nothing to set California’s water usage on a more sustainable path.

Statistical myths in California’s water shortage

Filed under: Bureaucracy, Economics, Environment, Media, USA — Tags: , , — Nicholas @ 02:00

Devin Nunes debunks the common claim that California’s farmers use “80 percent” of the available water in the state:

As the San Joaquin Valley undergoes its third decade of government-induced water shortages, the media suddenly took notice of the California water crisis after Governor Jerry Brown announced statewide water restrictions. In much of the coverage, supposedly powerful farmers were blamed for contributing to the problem by using too much water.

“Agriculture consumes a staggering 80 percent of California’s developed water, even as it accounts for only 2 percent of the state’s gross domestic product,” exclaimed Daily Beast writer Mark Hertsgaard in a piece titled “How Growers Gamed California’s Drought.” That 80-percent statistic was repeated in a Sacramento Bee article titled, “California agriculture, largely spared in new water restrictions, wields huge clout,” and in an ABC News article titled “California’s Drought Plan Mostly Lays Off Agriculture, Oil Industries.” Likewise, the New York Times dutifully reported, “The [State Water Resources Control Board] signaled that it was also about to further restrict water supplies to the agriculture industry, which consumes 80 percent of the water used in the state.”

This is a textbook example of how the media perpetuates a false narrative based on a phony statistic. Farmers do not use 80 percent of California’s water. In reality, 50 percent of the water that is captured by the state’s dams, reservoirs, aqueducts, and other infrastructure is diverted for environmental causes. Farmers, in fact, use 40 percent of the water supply. Environmentalists have manufactured the 80 percent statistic by deliberately excluding environmental diversions from their calculations. Furthermore, in many years there are additional millions of acre-feet of water that are simply flushed into the ocean due to a lack of storage capacity — a situation partly explained by environmental groups’ opposition to new water-storage projects.

Organic wines as mere marketing buzz and gimickry

Filed under: Business, Health, Science, Wine — Tags: , , , — Nicholas @ 02:00

At VinePair, Kathleen Willcox explains why the “organic” label on your wine may be little more than a marketing ploy:

A lot of the buzz and imagery about organics appears to be just that – empty sound bites and gimmicks created by folks eager to cash in on the increasingly lucrative organic market. Where does that leave us? Not in an easy place.

Falling for marketers’ ploys is practically a full-time occupation in America (I’m not the only one who’s bought multiple cartons of fat-free ice cream hoping, this time, to finally find “creamy fat-free vanilla bliss” right?). Consumers’ perception of what organic agriculture is vs. the reality, and the halo of virtue with which it is bequeathed (and conventional agriculture’s implicit pair of devil’s horns) is, arguably, one of the biggest boondoggles in our culture today. More than half of Americans (55%) go organic because they believe it’s healthier. Meanwhile, there is really no evidence to back that assumption up. And even organic farmers use pesticides (sorry random lady at the bar). They just happen to be “natural.”

It’s never been a better time for organic marketers and companies. The market for organic food and beverages worldwide was estimated to be $80.4 billion in 2013 and is set to reach $161.5 billion in 2018, a compound annual growth rate of 15% per year. North America has the biggest market share, and will be responsible for roughly $66.2 billion by 2018.

But in the rush to get organic products out the door (and fulfill the public’s desire for healthier, more environmentally responsible products), some producers are often doing little more than following the letter of the USDA law to earn the “organic” label, consequences to the environment and our overall health be damned. In fact, from what producers and studies revealed, it may actually be worse for the environment and your body to buy organic wine from a large manufacturer instead of buying wine produced from grapes on a smaller vineyard sprayed judiciously with synthetic pesticides by a hands-on farmer.

QotD: Pursuit of truth

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

Truth, indeed, is something that is believed in completely only by persons who have never tried personally to pursue it to its fastnesses and grab it by the tail. It is the adoration of second-rate men — men who always receive it at second-hand. Pedagogues believe in immutable truths and spend their lives trying to determine them and propagate them; the intellectual progress of man consists largely of a concerted effort to block and destroy their enterprise. Nine times out of ten, in the arts as in life, there is actually no truth to be discovered; there is only error to be exposed. In whole departments of human inquiry it seems to me quite unlikely that the truth ever will be discovered. Nevertheless, the rubber-stamp thinking of the world always makes the assumption that the exposure of an error is identical with the discovery of the truth — that error and truth are simple opposites. They are nothing of the sort. What the world turns to, when it has been cured of one error, is usually simply another error, and maybe one worse than the first one. This is the whole history of the intellect in brief. The average man of to-day does not believe in precisely the same imbecilities that the Greek of the fourth century before Christ believed in, but the things that he does believe in are often quite as idiotic. Perhaps this statement is a bit too sweeping. There is, year by year, a gradual accumulation of what may be called, provisionally, truths — there is a slow accretion of ideas that somehow manage to meet all practicable human tests, and so survive. But even so, it is risky to call them absolute truths. All that one may safely say of them is that no one, as yet, has demonstrated that they are errors. Soon or late, if experience teaches us anything, they are likely to succumb too. The profoundest truths of the Middle Ages are now laughed at by schoolboys. The profoundest truths of democracy will be laughed at, a few centuries hence, even by school-teachers.

There’s a reason SF writers tend to invent ways to travel interstellar distances quickly

Filed under: Books, Economics, Science, Space, Technology — Tags: — Nicholas @ 05:00

At Real Clear Science, Ross Pomeroy sings the praises of an early publication by the pre-Nobel academic Paul Krugman:

Paul Krugman is a Nobel Prize-winning economist, a respected professor at Princeton University, and an outspoken liberal columnist for the New York Times. But first and foremost, he is a huge nerd, and proud of it.

Back in the sweltering summer of 1978, Krugman’s geekiness prompted him to tackle a matter of galactic importance: the economics of interstellar trade. Then a 25-year-old “oppressed” assistant professor at Yale “caught up in the academic rat race,” Krugman crafted his “Theory of Interstellar Trade” to cheer himself up. Krugman’s jocularity is evident throughout the paper, which was published online in 2010, thirty-two years after he stamped it out on a typewriter. Early on in the article, he even pokes fun at his chosen profession:

    “While the subject of this paper is silly, the analysis actually does make sense. This paper, then, is a serious analysis of a ridiculous subject, which is of course the opposite of what is usual in economics”

The key problem with interstellar trade, Krugman writes, is time dilation. When objects travel at velocities approaching the speed of light — roughly 300,000 kilometers per second — time moves more slowly for them compared to objects at rest. (For a great explainer of this effect, which is tied to Einstein’s theory of special relativity, check out this video.) So the crew of a space-faring cargo ship might experience only ten years while thirty years or more might pass for the denizens of the planets they’re traveling between. How then, does one calculate interest rates on the cost of goods sold? Trading partners will undoubtedly be many light-years apart and trips will last decades, so this is a vital issue to resolve.

Since the speeds of vessels will undoubtedly vary, but both planets should be moving through space at close enough velocities where time dilation wouldn’t be a factor, Krugman contends that the interest costs should be tabulated based on the time shared by the two planets. But what about those interest rates? Won’t they differ? Not necessarily, Krugman argues. Competition should lead them to equalize amongst interplanetary trading partners.

Framing every conservation issue in terms of “extinction” is counter-productive

Filed under: Environment, Science — Tags: , , — Nicholas @ 04:00

Stewart Brand wants us to stop presenting so many conservation concerns in the headline-grabbing “Fluffy Bunnies At Risk!” format:

The way the public hears about conservation issues is nearly always in the mode of ‘[Beloved Animal] Threatened With Extinction’. That makes for electrifying headlines, but it misdirects concern. The loss of whole species is not the leading problem in conservation. The leading problem is the decline in wild animal populations, sometimes to a radical degree, often diminishing the health of whole ecosystems.

Viewing every conservation issue through the lens of extinction threat is simplistic and usually irrelevant. Worse, it introduces an emotional charge that makes the problem seem cosmic and overwhelming rather than local and solvable. It’s as if the entire field of human medicine were treated solely as a matter of death prevention. Every session with a doctor would begin: ‘Well, you’re dying. Let’s see if we can do anything to slow that down a little.’

Medicine is about health. So is conservation. And as with medicine, the trends for conservation in this century are looking bright. We are re-enriching some ecosystems we once depleted and slowing the depletion of others. Before I explain how we are doing that, let me spell out how exaggerated the focus on extinction has become and how it distorts the public perception of conservation.

Many now assume that we are in the midst of a human-caused ‘Sixth Mass Extinction’ to rival the one that killed off the dinosaurs 66 million years ago. But we’re not. The five historic mass extinctions eliminated 70 per cent or more of all species in a relatively short time. That is not going on now. ‘If all currently threatened species were to go extinct in a few centuries and that rate continued,’ began a recent Nature magazine introduction to a survey of wildlife losses, ‘the sixth mass extinction could come in a couple of centuries or a few millennia.’

The fossil record shows that biodiversity in the world has been increasing dramatically for 200 million years and is likely to continue. The two mass extinctions in that period (at 201 million and 66 million years ago) slowed the trend only temporarily. Genera are the next taxonomic level up from species and are easier to detect in fossils. The Phanerozoic is the 540-million-year period in which animal life has proliferated.

The range of dates in that statement reflects profound uncertainty about the current rate of extinction. Estimates vary a hundred-fold – from 0.01 per cent to 1 per cent of species being lost per decade. The phrase ‘all currently threatened species’ comes from the indispensable IUCN (International Union for Conservation of Nature), which maintains the Red List of endangered species. Its most recent report shows that of the 1.5 million identified species, and 76,199 studied by IUCN scientists, some 23,214 are deemed threatened with extinction. So, if all of those went extinct in the next few centuries, and the rate of extinction that killed them kept right on for hundreds or thousands of years more, then we might be at the beginning of a human-caused Sixth Mass Extinction.

Dog breeds in danger of extinction

Filed under: History, Science — Tags: , — Nicholas @ 05:00

Rosie Cima looks at the complex relationship between humans and dogs … dog breeds, that is:

Skye Terrier (via Wikipedia)

Skye Terrier (via Wikipedia)

Meet the Skye terrier. Named after the Scottish Isle of Skye, he’s one of the oldest terriers in the world — with a lineage tracing back to the Middle Ages. He’s also been a very popular dog in his day. Queen Victoria kept several as pets starting a fashion trend. Mary, Queen of Scots kept one, which hid under her skirt at her execution. Famously loyal, “plucky but dignified”, and an important cultural icon, this is the kind of dog people erect statues of. In fact, they have.

Want one? Better act fast: the breed could go extinct in your lifetime.

Skye terrier breeders are doing their best to change the tide, but things don’t look good. The global population is between 3,500 and 4,000, making the once-common breed one of the rarest in the world. Skye terriers are rarer than red pandas. In the UK, there were only 17 puppies of the Skye terrier breed registered in 2013. Breeders say they need 300 births a year to maintain a healthy population and avoid complications from inbreeding.

How did this happen?

For most of human/canine history, dog breeds evolved gradually, alongside human society, to fill different functional roles as they were needed. If a society or economy shifted, and the role was no longer needed, the breed ceased to exist. Those dogs were either bred for a different purpose or were subsumed into the general dog population.

The statistical anomalies of sex

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

As the old saying has it, “everyone lies about sex“:

Straight men have had twice as many sexual partners, on average, as straight women. Sounds plausible, seeing that men supposedly think about sex every seven seconds. Except that it’s mathematically impossible: in a closed population with as many men as women (which roughly there are) the averages should match up. Someone is being dishonest, but who? And why? These questions, along with many others, are explored in Sex by numbers, a new book by David Spiegelhalter, Winton Professor for the Public Understanding of Risk at the University of Cambridge.

“Sex is a great topic,” says Spiegelhalter. “There’s lots of it going on, but we don’t know what goes on or how much of it, because most of the time it goes on behind closed doors. It’s a really difficult topic to investigate scientifically, and a real challenge for statistics.” Spiegelhalter’s aim is to get people interested in a critical approach to the numbers they hear about in the news and give them the tools to figure out if they can be believed. “It’s really a book about statistics, using sex as an example.”

Statistics about sex are not all equally good. Some, like the number of births in a given year, are cast-iron facts, but others are much harder to come by. The number of sexual partners is a good example. The mismatch above comes from the third The National Survey of Sexual Attitudes and Lifestyles (Natsal), conducted between 2010 and 2012, in which men reported having had 14 sexual partners, on average, and women 7. Studies have suggested that women give lower numbers when they fear the survey isn’t entirely confidential, something that doesn’t seem to affect men (contrary to my expectation, it doesn’t induce them to exaggerate). So that’s one possible explanation for the mismatch: sadly, women still need to fear social stigma.

But there are other explanations too. One is that men (more than women) may have some of their sexual experience with sex workers. These aren’t included in the surveys, so their experiences are missing from the female tally. Another is that there are different attitudes as to what counts as a sexual partner. If a woman feels she’s been coerced by a man, for example, she may not want to count him.

The latest “breakthrough” in helping schizophrenics take their medicine

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

Scott Alexander recently attended a local psychiatry conference, with some essential themes being emphasized:

This conference consisted of a series of talks about all the most important issues of the day, like ‘The Menace Of Psychologists Being Allowed To Prescribe Medication’, ‘How To Be An Advocate For Important Issues Affecting Your Patients Such As The Possibility That Psychologists Might Be Allowed To Prescribe Them Medication’, and ‘Protecting Members Of Disadvantaged Communities From Psychologists Prescribing Them Medication’.

As somebody who’s noticed that the average waiting list for a desperately ill person to see a psychiatrist is approaching the twelve month mark in some places, I was pretty okay with psychologists prescribing medication. The scare stories about how psychologists might prescribe medications unsafely didn’t have much effect on me, since I continue to believe that putting antidepressants in a vending machine would be a more safety-conscious system than what we have now (a vending machine would at least limit antidepressants to people who have $1.25 in change; the average primary care doctor is nowhere near that selective). Annnnnyway, this made me kind of uncomfortable at the conference and I Struck A Courageous Blow Against The Cartelization Of Medicine by sneaking out without putting my name on their mailing list.

But before I did, I managed to take some notes about what’s going on in the wider psychiatric world, including:

– The newest breakthrough in ensuring schizophrenic people take their medication (a hard problem!) is bundling the pills with an ingestable computer chip that transmits data from the patient’s stomach. It’s a bold plan, somewhat complicated by the fact that one of the most common symptoms of schizophrenia is the paranoid fear that somebody has implanted a chip in your body to monitor you. Can you imagine being a schizophrenic guy who has to explain to your new doctor that your old doctor put computer chips in your pills to monitor you? Yikes. If they go through with this, I hope they publish the results in the form of a sequel to The Three Christs of Ypsilanti.

– The same team is working on a smartphone app to detect schizophrenic relapses. The system uses GPS to monitor location, accelerometer to detect movements, and microphone to check tone of voice and speaking pattern, then throws it into a machine learning system that tries to differentiate psychotic from normal behavior (for example, psychotic people might speak faster, or rock back and forth a lot). Again, interesting idea. But again, one of the most common paranoid schizophrenic delusions is that their electronic devices are monitoring everything they do. If you make every one of a psychotic person’s delusions come true, such that they no longer have any beliefs that do not correspond to reality, does that technically mean you’ve cured them? I don’t know, but I’m glad we have people investigating this important issue.

Moral panics and “Shaken Baby Syndrome”

Filed under: Health, Law, Media, Politics, USA — Tags: , , — Nicholas @ 04:00

In L.A. Weekly, Amy Nicholson looks at a new documentary:

It’s never simple when science suffers a shakeup. The road to the truth is littered with fallen experts who were disgraced when they tried to disprove — or prove — the common wisdom, be it that the earth revolves around the sun or that witches float. Today’s researchers are fighting to restore logic in the debate over vaccinations, global warming, and the increasingly hazy medical condition called Shaken Baby Syndrome, whose adherents accuse, pursue and prosecute an estimated 250 parents, babysitters and other caretakers each year.

Veteran investigative journalist Susan Goldsmith has spent years examining the medical and legal industry that has arisen to promote its belief that vicious baby-shaking by enraged adults has killed thousands of infants, the subject of the new documentary, The Syndrome, researched by Goldsmith and directed by her cousin Meryl Goldsmith.

“I made a career writing about child abuse,” she says. Her child abuse investigations as a reporter for The Oregonian led to two new laws designed to better protect kids in foster care. Yet, she also sees extreme, unfounded reactions by well-meaning people when children are involved. Says Goldsmith, “When people hear ‘child abuse,’ all thinking just goes into shutdown mode.”

A diagnosis of Shaken Baby Syndrome was supposed to explain mysterious deaths in babies without bone fractures, bumps, bruises or neck injuries. How did they die? A theory arose that babies were under attack by loved ones. For decades, doctors in the U.S., and dozens of other countries were trained to look for three internal symptoms that experts claimed were proof of a powerful shaking assault on a tiny child: brain swelling, blood on the surface of the brain, and blood behind the eyes. Well-meaning doctors were instructed that these symptoms could only occur due to intense shaking — if a parent or babysitter said the child had fallen or suddenly fell ill, that was a lie.

Proponents of the theory grew so powerful in political circles, where elected officials were keen to show they supported helpless children, that laws were passed across the U.S. requiring a doctor who spotted any of the three symptom to alert authorities. Failure to report symptoms, even if a doctor found the parents’ explanation made sense, could result in fines, civil lawsuits, or even jail time.

We’ve been here before. The Syndrome rewinds back to the 1980s when the big public panic on behalf of children was Satanic Ritual Abuse, a Salem-like national frenzy in which prosecutors and juries in big cities and small towns sent daycare employees to jail for years for crimes as implausible as cutting off a gorilla’s finger while at the zoo, then flying the children over Mexico to molest them.
