QotD: The pastries of the wider paradonut family
When people say “I’d like a donut”, #Science indicates that Actually, they don’t want a donut at all. They say donut, but they really mean a pastry from the paradonut family.
Exhibit A: The Coffee Roll — Phasers on Star Trek have three settings: Stun, Kill, and Coffee Roll.
Exhibit B: The Eclair — From the French for “lightning”, the eclair was invented by a psychiatrist as a delicious alternative to electroshock therapy for schizophrenics. Because when you’re eating an eclair, you can’t deny the marvelous cream-filled reality you’re actually present in.
Exhibit C: The Cheese Danish — Cheese Danishes have a mix of flavors and textures that make them, in scientific terms, “a gang-bang for your face”.
Exhibit D: The Bear Claw — The bear claw is the ugly, bewarted King Pimp of the pastry shop window, with a dozen smaller, more effeminate donuts it’s turned into its sad little bitches and tricks following behind it.
Exhibit E: The Apple Fritter — The so-called “Emperor of Pastries” makes your stupid little glazed donut look sad and weak like Barack Obama’s gay arms.
Exhibit F: The Cinnamon Bun — Cinnamon Buns have been proven to be responsible for America’s obesity epidemic and diabetic crisis, and also totally worth it.
Bonus: Worst Donuts
1. Jelly Donuts — Jelly donuts are always what’s left after people eat the real donuts. Jelly donuts are consolation prizes for losers who came late. They taste like failure for a reason. If you’re eating a jelly donut, that’s because you’re not a competitor and you don’t have any friends to set aside a good donut for you.
2. Plain Donuts — Plain donuts are also called “not donuts” or “ring-shaped bread”. Plain donuts were invented for parents who don’t love their children. They are also sometimes put out as bait for poisoning rats, though they have a 75% failure rate. Rats don’t like them either. Sometimes a poisoned plain donut will be found intact, with a dead rat next to it — rats will lick the poison off the plain donut while avoiding the plain donut itself. According to Leviticus, you are supposed to pay the dowry of an ugly woman in plain donuts.
3. Powdered Sugar Donuts — Powdered sugar donuts are made primarily by mental degenerates employed by donut shops as charity hires. They are sometimes called “Retard Donuts”. To compare powdered sugar donuts to the Holocaust would be to trivialize the horror of powdered sugar donuts.

The clear drawbacks of depending too much on oral history
In The Line, Jen Gerson explains why you need to exercise caution when dealing with oral traditions:

A BBC travel feature published several weeks ago had the hallmarks of a classic progressive narrative. It was the tale of the “endangered Ojibwe spirit horse; the breed, also known as the Lac La Croix Indian pony, is the only known indigenous horse breed in Canada.”
The spirit horse was reduced to near extinction by European settlers who treat these magical creatures, deemed “guides and teachers”, as a mere nuisance to be culled and eliminated in favour of more profitable animals like cattle, or so the telling goes. A native breed of a beloved animal struggling to survive in the face of voracious colonial settlers.
Someone call James Cameron.
Unless you know a little evolutionary history, that is. In which case, you will already be aware that this story is pure pseudoscientific hokum.
Look, no one likes to be disrespectful about sensitive matters where the legitimately oppressed and aggrieved claims of First Nations peoples are concerned. This is a nation that is struggling to come to terms with its own horrific colonial past. This process is taking on many forms: witness the applause granted to singer Jully Black, who recently amended the national anthem “our home on native land”. Or, perhaps, the calls by one NDP MP to combat residential school denialism by passing new laws on hate speech — which would make questioning certain narratives not only an act of heresy, but also a literal crime.
Listening to stories, and respecting lived experiences and oral histories Indigenous people at the core of Canadian history and identity has given a new credibility to the traditional knowledge of First Nations people in academia, media, and in society at large.
But the story of the Ojibwe spirit horse is a clear example of the limits of oral history.
The horses now roaming the plains of North America are not a native species. The horse did evolve on this continent before migrating to Asia and Europe. However, the North American breed is believed to have been extirpated about 10,000 years ago (or thereabouts) during a mass extinction event that wiped out almost all large land mammals.
There is some evidence that isolated pockets of a native horse breed may have survived in North America much later than this, but the horses roaming about today are descended from those that were brought from Europe after the 15th century.
Of course, science is always evolving, but the overwhelming bulk of genetic and archeological evidence to date supports this theory. The native North American horse is long, long gone. The bands of horses freely wandering the backcountry are not wild, but feral; they’re the product of escaped or abandoned horse stock of distant European origin.

Persistent fantasies about lost Ice Age civilizations
When I was a teen, there seemed to be a lot of pop-sci books on the racks at our local variety store pushing various notions about “highly advanced” but lost civilizations, often attributing things like UFO sightings to these imagined prehistoric groups and tying various conspiracy theories back to them. At Astral Codex Ten, Scott Alexander argues against today’s fans of such unlikely scenarios:
You can separate these kinds of claims into three categories:
- Civilizations about as advanced as the people who built Stonehenge
- Civilizations about as advanced as Pharaonic Egypt
- Civilizations about as advanced as 1700s Great Britain
The debate is confused by people doing a bad job clarifying which of these categories they’re proposing, or not being aware that the other categories exist.
2 and 3 aren’t straw men. Robert Schoch says the Sphinx was built in 9700 BC, which I think qualifies as 2. Graham Hancock suggests “ancient sea kings” drew the Piri Reis map which seems to depict Antarctica; anyone who can explore Antarctica must be at least close to 1700s-British level.
I think there’s weak evidence against level 1 civilizations, and strong evidence against level 2 or 3 civilizations.
Argument 1: Where Are The Sites?
Supporters of ice age civilizations argue that sea level rose 120 meters as the Ice Age glaciers melted, flooding low-lying coasts and destroying any evidence of coastal civilizations.
Areas likely above water during the Ice Age are in orange-brown (source)
What would happen to the ancient civilizations we know about if sea level rose an additional 120m? We would lose Babylon, Rome, and most of Egypt. But:
- The Acropolis of Athens is 150m above sea level, and would be preserved for future archaeologists. Sparta (200m) and Thebes (250m) would also be fine.
- The Hittite capital of Hattusa is almost 1,000m above sea level and would be totally unaffected.
- The two biggest cities in Assyria, Ashur and Nineveh, would both make it.
- Zhengzhou, the capital of the Shang in ancient Chinese, would survive.
- Mohenjo-Daro would sink, but Harappa would be fine.
- Basically nobody in Elam/Medea/Persia would even notice.
- The top 80m of the Great Pyramid would rise above the waterline, forming a little island. The part of the Pyramid above the water would still be taller than the entire Leaning Tower of Pisa. It would be pretty hard to miss!
So a 120m sea level rise wouldn’t be enough to wipe out evidence of our crop of ancient civilizations, and shouldn’t be enough to wipe out evidence of a previous crop, unless they had a very different geographic distribution than ours.

The instinct to protect
Rob Henderson on the way that women react to men who demonstrate protective instincts toward them:
Human psychology evolved in environments far more violent than even the most dangerous modern U.S. cities. Overall, in the U.S., the average death rates from interpersonal violence are less than 1 in 10,000.
In contrast, in hunter-gatherer societies, 15 percent of deaths were the result of physical violence.
Our violent evolutionary past has shaped our minds. Even peaceable people in developed countries who have never even been in a fight can still readily estimate men’s physical strength from their face, body, and voice. These estimations tightly correlate with men’s actual physical strength.
A 2022 paper (preprint link here) investigated whether people prefer romantic partners who are willing and able to protect them from violence.
Considering the frequency and intensity of violence in the human ancestral environment, affiliating with people who were able to protect you would have been advantageous. The authors of the paper suggest such preferences have shaped human mating psychology.
The authors (Barlev, Arai, Tooby, and Cosmides) explore the question of whether a potential partner’s ability to protect you from violence is valued. It seems obvious that the answer (especially for women) is almost certainly yes.
However, they also explore whether a potential partner’s willingness (independent of ability) is also considered attractive.
When a woman judges a man, does learning that he is willing to protect her from violence make him more attractive, even if he isn’t particularly effective at doing so?
What about when a woman learns that a man is able but unwilling to protect her? Imagine a muscular guy who, upon seeing his date get mugged, just stands there and does nothing, or runs away.
Is he still more attractive than a guy who is unable but willing to protect her? Picture a scrawny guy who, upon seeing his date get mugged, physically tries but is unsuccessful in his attempt to stop the mugger.
The paper explores these questions.
[…]
Here you see that women rate male dates (described in this particular version of the study as average in physical strength and average in physical attractiveness) who make no attempt to protect them as a 2 out of 10 in attractiveness. Women rate a man who attempts to protect them but fails as a 7.5 out of 10. And a man who attempts to protect them and succeeds is an 8 out of 10.
So the major bump in attractiveness comes from willingness, rather than ability.
QotD: Sigmund Freud’s insights
Sigmund Freud was a perverted old cokehead, but he had some useful insights. One of them is that anxiety works like a spring (my paraphrase). You need a spring to have a certain tension in order to work, but if you compress it too tightly, it breaks. Anxiety that can’t be discharged (his term) in healthy, socially beneficial ways instead gets discharged in unhealthy, neurotic ways.
That’s what happened with Anna O., history’s most famous psychiatric patient. She had a very turbulent love/hate relationship with her father, as tightly wound girls do. When he became deathly ill on a family vacation, the unresolvable tension caused a whole host of physical symptoms, including hysterical paralysis. Pioneering psychologist Josef Breuer “talked her through” it, finally resolving the emotional conflict and “curing” the patient.
All this would’ve been interesting, but largely irrelevant, were it not for World War I. The world at large didn’t care about the problems of overprivileged Jewish girls, but they did care about their soldiers suddenly going crazy in the trenches. Once military doctors finally ruled out a physical cause, they were left with Freudian explanations: A soldier can’t stop fighting, because he’s an honorable, dutiful soldier. Yet that soldier must stop fighting. The only honorable way out is a wound. If the enemy doesn’t wound him, then, his subconscious will. Hence the bizarre “conversion disorders” — hysterical blindness, paralysis, mutism, etc. — characteristic of “shell shock.”
But a funny thing happened. While everyone now acknowledged the real power of the subconscious mind, we sort of … forgot … about it. Psychology, particularly psychotherapy, went back to being a ghetto Jewish preoccupation. Bored, over-privileged housewives might go to a shrink to talk through their “issues”, but as for the rest of us, well, if we weren’t going into combat anytime soon, why bother? Outside of a few crusty old reactionaries (like yours truly) making fun of SJWs, when was the last time you heard the word “neurotic”?
But that’s the thing: either the subconscious is real, or it isn’t. When we say “neurotic” (the few of us who still do), we usually mean people like Anna O. — rich, cosseted, politically active human toothaches who try to force the entire world into the all-encompassing drama of their Daddy Issues (see also: Virginia Woolf). But that’s not how Freud meant it. According to him, we’re all neurotic to some degree or another, because that’s just how anxiety works.
We all have strong emotional impulses that run counter our self-image. Hence the entire panoply of pop-Freudianism: The preacher who constantly rails against homosexuality from the pulpit is secretly gay (“projection”). The strict, controlling, everything-in-its-place type is a sadist (“anal-retentive”). The player who can’t settle down with any woman is actually trying to find a Mommy figure (“Oedipus complex”). And, of course, the — ahem — daddy of them all, the crippling Daddy Issues that make feminists such fun.
But that’s just the thing: Either anxiety works that way or it doesn’t. Just because we don’t see a specific syndrome in ourselves doesn’t mean we don’t have a whole bunch of anxiety we need to discharge. Just because it’s subclinical, in other words, doesn’t mean it’s not real, or unimportant. See for example the legions of keyboard commandos who show up in the comments of any blog with more than fourteen readers. Yeah, sure, it’s possible that those guys all got kicked out of SEAL Team 6 for being too badass … but it’s probably classic identification. They’re deeply uneasy about the world and their place in it, so they construct themselves an identity as the Rambo of Evergreen Terrace.

QotD: Scientology versus psychiatry
Scientology has a long-standing feud with psychiatry, with the psychiatrists alleging that Scientology is a malicious cult, and the Scientologists alleging that psychiatry is an evil pseudoscience that denies the truth of dianetics. And that psychiatrists helped inspire Hitler. And that the 9/11 was masterminded by Osama bin Laden’s psychiatrist. And that psychiatrists are plotting to institute a one-world government. And that psychiatrists are malevolent aliens from a planet called Farsec. Really they have a lot of allegations.

“… sub-replacement fertility is probably an inevitable product of female emancipation”
In Ed West’s weekly round-up, he ends the post on this rather grim (from a demographic viewpoint) note:
In The Guardian, Martha Gill on the great vexation of modern life: people can’t have as many children as they’d like.
OK: so it’s about social structures, then? Lack of childcare, unequal parental leave and career penalties for mothers. Not so – or not primarily. In our fecund recent past, remember, career penalties for mothers were even higher. Mothers still suffer a career penalty almost everywhere, but attempting to remove it doesn’t seem to alter their decisions that much. Since 2008, amid unequalled progress in gender equality and some of the most generous parental support schemes on the planet, birthrates in Sweden, Norway and Iceland have fallen precipitously. Nordic countries are, comparatively, parental utopias, yet birthrates tick along slightly above the EU average and still well below the replacement rate.
I agree with her basic premise. Aside from Georgia, no country has successful brought fertility rates above replacement rates, whatever the childcare incentives, because sub-replacement fertility is probably an inevitable product of female emancipation. In particular the issue is that women don’t tend to marry men with lower education and income levels, so the modern system ensures that a large minority of men are simply unmarriagable.
I’m not convinced by Gill’s solution, since outcomes for the children of single parents are way worse on average, and even with huge state support it’s going to be incredibly hard to raise children alone. Even without grandparental support it’s hard with two parents. I also think this problem is inevitably helping the drive towards poly-acceptance. As Rob Henderson wrote earlier this month:
In a deregulated market, power laws dominate. This is true not only in the economic realm, but in the romantic realm as well. At no point in history have all men in a given society been equally desirable. Today, though, the disparity between men is particularly pronounced. And the gap shows no sign of slowing or closing. The polyamorous movement may be a reaction to shifts in sex ratios among attractive individuals. Many individuals who do not identify as poly are likely practicing some version of it, knowingly or otherwise, as the case of West Elm Caleb demonstrated. The majority desirable young males using dating apps almost certainly have at least three women in their rotation, if not more.
As with so many things, post-Christian society is reverting to pre-Christian norms, in this case the norm where a large proportion of men were thrown onto the romantic scrapheap.

J.K. Rowling’s critics reach the “Burn the witch!” phase
In The Free Press, Megan Phelps-Roper introduces a new audio series featuring extensive interaction with J.K. Rowling herself:

J.K. Rowling’s Harry Potter books were insanely popular among Millennials until she had the temerity to say things the Trans* activists hated. Now, they try to sell customized copies of her books that omit her name completely.
J.K. Rowling is arguably the most successful author in the history of publishing, with the possible exception of God. And “Harry Potter” was a kind of bible for my generation. Since its publication beginning in the late ’90s, the series has taught tens of millions of children about virtues like loyalty, courage, and love — about the inclusion of outsiders and the celebration of difference. The books illustrated the idea of moral complexity, how a person who may at first appear sinister can turn out to be a hero after all.
The author herself became part of the legend, too. A broke, abused, and depressed single mother — writing in longhand at cafes across Edinburgh while her baby girl slept in a stroller beside her — she had spun a tale that begat a global phenomenon. If “Harry Potter” was a bible, then Rowling became a kind of saint.
When she gave the Harvard commencement address in 2008, she was introduced as a social, moral, and political inspiration. Her speech that day was partly about imagination: “the power that enables us to empathize with humans whose experiences we have never shared”.
“We do not need magic to transform our world,” Rowling told the rapt audience. “We carry all the power we need inside ourselves already.”
The uproarious applause that greeted her in 2008 is hard to imagine today. It’s hard to imagine Harvard — let alone any prestigious American university — welcoming Rowling. Indeed, I’m not sure she’d be allowed to give a reading at many local libraries.
That’s because to many, Rowling has since become a kind of Voldemort — the villain of villains in her own stories.
It all blew up in the summer of 2020.
“‘People who menstruate'”, Rowling wrote on Twitter, quoting a headline. “I’m sure there used to be a word for those people. Someone help me out. Wumben? Wimpund? Woomud?”
She continued: “If sex isn’t real, there’s no same-sex attraction. If sex isn’t real, the lived reality of women globally is erased. I know and love trans people, but erasing the concept of sex removes the ability of many to meaningfully discuss their lives. It isn’t hate to speak the truth.”
It’s hard to capture the breadth of the firestorm that followed.

Appliance futility by design
Tal Bachman recounts a miserable — but increasingly common — experience with modern “energy efficient” home appliances:

“A-rated energy appliances” by Tom Raftery is licensed under CC BY-NC-SA 2.0
The LG 5.8 cubic foot Capacity Top Load Washer sat in the laundry room, brand new. Maybe it was my imagination, but it looked insouciant.
Dad said it was the latest and greatest in laundering technology. Supposedly, some sort of internal sensor system (having something to do with a computer) fine-tuned water levels depending on clothing weight. Or something. I can’t remember exactly what he — or was it the moving guy? — said.
I did notice the washing machine had several preset wash cycles — Allergiene, Sanitary, Bright Whites, Towels, Heavy Duty, Bedding, and more. You could select them with a shiny, space-age-looking chrome dial. (I would later discover the machine had other fancy features with names like TurboWash™ 360, ENERGY STAR® Qualified, Smart Diagnosis™, and ThinQ™ Technology [Wi-Fi Enabled]).
[…]
Well, it was win-win-win, with a minor caveat. The caveat was the washing machine. Turns out that for all its razzle-dazzle features, it didn’t actually clean clothes. Even worse, it took hours to not clean clothes. The “Allergiene” cycle, for example, took almost four hours. Yet when you pulled your clothes out, you could still make out the orange juice or tomato sauce stains. I’d never encountered a more useless washing machine.
“How you feeling about this new washing machine?”, I asked Dad, a few days after the hunkering down began.
“Great!”, said Dad.Okay, I thought. That’s not unusual. Music — as opposed to the mundane or practical — occupies most of Dad’s awareness, and always has. Besides, most of his clothes are black, and he probably hasn’t noticed it’s not removing the ketchup stains. Maybe he will in a few weeks.
And maybe in the meantime, I thought, I could figure out a way to reprogram the machine for cycles which actually washed. And were faster.
But no. That turned out to be way too much to hope for. The machine allowed no independent control over water volume, cycle time, or water temperatures. It only allowed selection of a preset computerized cycle — none of which got your clothes clean.
[…]
Yet more irritating was the reason it skimped on water and power: it was trying to stop global warming. Oops — I mean “climate change”. It was “environmentally friendly”. Except it wasn’t, because you usually had to run at least two cycles to get your clothes clean. That’s right: you had to use the same amount of water in the end anyway, and double the electricity.
And so — not for the first time — I had stumbled upon yet another example of technological “progress” which exacerbated the very (pseudo) problem it purported to solve. The new useless LG “Save the World!” piece of garbage was the home equivalent of Hollywood stars taking private jets to a carbon reduction conference in Switzerland.
[…]
The US Department of Energy, I discovered, had begun imposing energy efficiency regulations in the early 1990s. A decade later, they made the regulations even stricter (see here also). Then, as the years passed, they made them even stricter. And then stricter. And then stricter. All the while, the feds offered appliance manufacturers huge tax incentives — i.e., huge cash rewards — to accelerate their phase out of functional washing machines.
Government succeeded. Today, minus the loophole-exploiting Speed-King (which the feds will probably crush soon), you cannot find a new washing machine — front- or top-loading — which washes clothes anywhere near as well as its predecessors. The rationale for this — saving the world from global warming — doesn’t even rise to the level of ludicrous. Just for starters, as I type this, we’re enduring one of the coldest winters ever recorded. New Hampshire’s Mount Washington Observatory just recorded a wind chill calculation of minus 109 degrees Farenheit, an all-time record for the United States (and approaching midway between the average temperatures of Jupiter and Mars). Temperatures are thirty degrees Farenheit colder than average in many places. Why would anyone want to bring temperatures down even further? And at the cost of destroying washing machine functionality? And what loon could actually believe home washing machines change the climate?
In any case, thanks to an essentially totalitarian government run by bought-and-paid-for liars, control freaks, and imbeciles, we have gone technologically backward — certainly in the appliance domain, but in others — for no good reason at all. (Regulations have also downgraded dishwashers, toilets, showers, and other appliances, but we can discuss those another time)
Back in 2019, Sarah Hoyt expressed her frustrations with “modern” “energy-efficient” appliances which matched our experiences exactly.
