Psychotic people follow scripts.

Let's talk about the glass delusion, the Middle Ages' bout with a mass psychogenic illness marked by people believing they were made of glass. Image
Glass was a valuable commodity in Europe. It was primarily owned by the noble and well-to-do, and it had a notable purpose in alchemy.

Its perception as the technology of the time was as one that's both fragile and valuable, like the nobility. Image
Glass was the relatively novel technology people knew, and they knew things could be transmuted into glass. Delusional people also thought transmutation could affect them.

Take King Charles VI.

He truly believed his body was made of glass. Image
This delusion was such that Charles felt he had to build his life around it.

He had iron rods fastened into his clothing to hold him up, and he didn't allow his advisors to approach him, lest they accidentally shatter him.

This illness set in during his twenties. Image
The age when his psychotic bouts started is remarkably consistent with when the illness starts today.

Were he alive today, he probably would have been prescribed antipsychotics for his condition. Image
But Charles was alive long before his condition was understood.

He also wasn't its only sufferer. As alchemy's popularity grew, more people started to suffer the glass delusion.

They understood glass as fragile, and themselves as fragile, and they acted out that script. Image
For the well-off, the delusion was treated as legitimate. Many nobles came to wear padded buttocks.

But in one case, in Saint Germain, a doctor took a man who thought his butt was made of glass and beat him until he stopped believing in the delusion.

Apparently that worked. Image
Amusingly, in Rene Descartes' Meditations on First Philosophy, he remarked on the glass delusion and used it as an example of how people can see the world in totally different ways.

Of course, he did say that the perception was insane.Image
Fast forward to the 19th century and factories are beginning to dot the landscape of Europe.

With the change in popular technology, people's delusions followed suit.

With industry, the delusions became industrial. People imagined they were being influenced by vast machines. Image
Patients who presented with this belief in intricate, far off machines that controlled their actions and influenced their lives could never explain how they worked.

Just as people didn't know how they became glass, they didn't get how machines were affecting them. Image
Factories influenced the world, machines could obviously influence us, thus...

Schizophrenics' delusions are tailored to what they vaguely know, and they learn about those half-baked delusions from others, the times, etc.

Consider exorcism. Its modern script came from a movie! Image
People today know about parasites, chronic pain, post-viral conditions, toxic poisoning, and more, and they have an amazing tool for finding and promoting related scripts:

The internet! Image
Thousands of people today believe they have a skin condition called Morgellons.

It's not real.

They just believe they're developing sores and lesions, and hairs are sprouting from them, but they're really picking themselves raw and getting freaked out by cotton fibers. Image
The sufferers from this condition are deeply unwell, and they spread their unwellness to other people through posting about their condition online.

People know about all the requisite concepts, and they see something on themselves and imagine it's a real symptom.

But it's not.
There are no demons, there's no Morgellons, people cannot be made of glass, and there's no big machine out there influencing people and miraculously disappearing the moment those concepts go out of fashion and get replaced by other ones with nary a cure invented.
And this keeps happening!

People are always inventing new conditions or imagining they're afflicted by something real when they're not, by reading into symptoms and gaslighting themselves.

And they sometimes act incredibly mad in these bouts of belief. Image
A subset of people today seem vulnerable to scripts, and some seem to have always been vulnerable to it.

It makes you wonder: must psychotic people always be like this? And what can we do to cure them of their delusions?

I suggest we don't give in with padded buttocks.

I'm going to humbly request that everyone stop dunking on John when he isn't even wrong.

Firstly, the reason for the hollowed out middle between -1.96 and 1.96 (p = 0.05) is not due to calculating CIs from abstracts instead of full-texts.

The original source showed that!Image
The original source for the Medline p-values explicitly compared the distributions in the abstracts and full-texts.

They found that there was a kink such that positive results had excess lower-bounds above 1 and negative results had excess upper-bounds below 1.Image
They then explicitly compared the distributional kinkiness from Medline to the distributions from an earlier paper that was similar to a specification curve analysis.

That meant comparing Medline to a result that was definitely not subject to p-hacking or publication bias. Image

I got blocked for this meager bit of pushback on an obviously wrong idea lol.

Seriously:

Anyone claiming that von Neumann was tutored into being a genius is high on crack. He could recite the lines from any page of any book he ever read. That's not education!
'So, what's your theory on how von Neumann could tell you the exact weights and dimensions of objects without measuring tape or a scale?'

'Ah, it was the education that was provided to him, much like the education provided to his brothers and cousins.' Image
'How could his teachers have set him up to connect totally disparate fields in unique ways, especially given that every teacher who ever talked about him noted that he was much smarter than them and they found it hard to teach him?'

'Education, OK???' Image

A new study just came out on this topic.

Using data from almost 14 million young people in England, they found that COVID—but not COVID vaccination—was broadly associated with heart problems.

The myocarditis bump (which is milder than real myocarditis) was also small.Image
This study also provides more to differentiate viral myocarditis from vaccine """myocarditis""", which again, is mild, resolves quickly, etc., unlike real myocarditis.

To see what it is, first look at this plot, showing COVID infection risks by time since diagnosis: Image
Now look at risks since injection.

See the difference?

The risks related to infection hold up for a year or more. The risks related to injection, by contrast, are short-term.Image

This analysis falls flat when you look into these people or think about how so many other "vons" were not as brilliant.

Von Neumann's brilliance preceded formal education and any tutoring. His advanced math tutor noted that he was smarter than him from their first meeting!Image
Von Neumann was noted to be eidetic by 3.

By 6 he could divide two 8-digit numbers immediately in his head.

He picked up multiple languages by 7, long before his similarly-instructed cousins and brothers.

By 8, he could do calculus.

His precocity *inspired* hiring a tutor. Image
Absolutely tons of upper-bourgeois families in Budapest supplemented schooling with tutors, governesses, etc.

But von Neumann—who had far from the best education among them—outmatched them with ease.

Moreover, he had plenty of superhuman abilities! Image

What do studies say about "freezing the rent"?

Let's have a thread🧵

First thing's first: Most studies agree that rent controlled units have lower rents, but also the supply of rentable units goes down and un-controlled units see their rents increase.

Uh-oh! Image
Rent control also means that fewer homes get built, and it means that housing quality drops.

After all, if you can't raise the rent, what incentive do you have to make everything sparkly and neat? Image
Rent control lowers residential mobility, meaning people stay put longer

That's not good because it causes misallocation

Consider an elderly family whose kids left the nest. They should move to a smaller place, but rent control keeps them in place, so new families can't move in Image

I'm not taking a stance on whether inflammation drives cancer, but I will say it's very true that GLP-1 drugs reduce inflammation—a lot!

Tirzepatide at any dose greatly reduced levels of high-sensitivity C-reactive protein and interleukin-6, two important inflammation markers: Image
I have actually had people thank me for getting them on this stuff precisely because they had inflammation issues that these drugs *immediately* solved for them.

Here's an example I've posted before: this man's back pain was cured!
