American military veterans have a suicide problem.

Some have theorized the reason is deployment-related trauma.

Leveraging the random assignment of new soldiers to units with different deployment cycles, Bruhn et al. found that was wrong.

Deployment did not increase suicides. Image
Looking only at violent deployments (ones with peer casualties), there aren't noncombat mortality effects either.

What explains veteran suicide rates? Image
The reason seems to be that the proposition is wrong: veterans do not have increased suicide risk.

This may seem surprising, but it's not. Their suicide rates are elevated over the general population because most of them are young White men. That group has a suicide issue. Image
There are good and bad parts to this observation.

On the one hand, it means that there is not selection of suicidal people into the military.

On the other, demographic selection makes this problem into one that agencies like the VA will probably not be able to fix on their own
because it's not a soldier problem, it's a young White male problem.

I don't know how this can be fixed, but presumably tackling opiate use would help.

Soliman (2022) found that DEA crackdowns on overprescribing pharmacies resulted in fewer local suicide deaths. Image
Soliman also found that sanctioning specific doctors affected opioid-related mortality more generally without impacting suicide rates. Effects were generally larger for males than females and they were larger for people aged 30-49 than those aged 15-29 or 85+. No race data.
Kennedy-Hendricks et al. found that Florida's pill mill crackdown reduced opioid overdose mortality considerably.

Their supplement contained details on the characteristics of the people who died from opioid overdoses, but I wasn't able to access it.

Regardless, this problem can Image

New Pangram validation!

You know how most books on Amazon are AI slop now? If you didn't, look at the publication numbers.

Compare those to the proportion Pangram flags as AI-generated. It's fully aligned with the implied numbers based on the rise over 2022 publication levels! Image
Similarly, the rise of pro se litigants has come with a rise in case filings detected as being AI-generated, and with virtually zero false-positives before AI was around.

You can also see the rise of AI-generated text and yet more evidence for Pangram's validity from looking at different journalists.

Large portions of the journalistic profession are lazy, so they cheat when they can.

For example, the Guardian's Bryan Graham = slop Image

Pierre Guillaume Frédéric le Play argued that France's early fertility decline was driven by its inheritance reforms, where estates had to be split up equally to all of the kids, including the girls.

There's likely something to this!🧵 Image
For reference, the French Revolution ushered in a number of egalitarian laws.

A major example of these had to do with inheritance, and in particular with partibility.

In some areas of France, there was partible inheritance, and in others, it was impartible. Image
Partible inheritance refers to inheritance spread among all of a person's heirs, sometimes including girls, sometimes not.

Impartible inheritance on the other hands refers to the situation where the head of an estate can nominate a particular heir to get all or a select portion. Image

In terms of their employment, religion, and sex, people who joined the Nazi party started off incredibly distinct from the people in their communities.

It's only near the end of WWII when they started resembling everyday Germans. Image
Early on, a lot of this dissimilarity is due to hysteresis.

Even as the party was growing, people were selectively recruited because they were often recruited by their out-of-place friends, and they were themselves out-of-place.

It took huge growth to break that. Image
And you can see the decline of fervor based on the decline of Nazi imagery in people's portraits.

And while this is observed by-and-large, it's not observed among the SS, who had a consistently higher rate of symbolic fanaticism. Image

I simulated 100,000 people to show how often people are "thrice-exceptional": Smart, stable, and exceptionally hard-working.

I've highlighted these people in red in this chart: Image
If you reorient the chart to a bird's eye view, it looks like this: Image
In short, there are not many people who are thrice-exceptional, in the sense of being at least +2 standard deviations in conscientiousness, emotional stability (i.e., inverse neuroticism), and intelligence.

To replicate this, use 42 as the seed and assume linearity and normality

I would like to live in a high-trust society.

The decline of trust is something worth caring about, and reversing it is something worth doing.

We should not have to live constantly wondering if we're being lied to or scammed. Trust should be possible again.
I don't know how we go about regaining trust and promoting trustworthiness in society.

It feels like there's an immense level of toleration of untrustworthy behavior from everyone: scams are openly funded; academics congratulate their fraudster peers; all content is now slop.
What China's doing—corruption crackdowns and arresting fraudsters—seems laudable, and I think the U.S. and other Western nations should follow suit.

Fraud leads to so many lives being lost and so much progress being halted or delayed.

I'm close to being single-issue on this.

British fertility abruptly fell after one important court case: the Bradlaugh-Besant trial🧵

You can see its impact very visibly on this chart: Image
The trial involved Annie Besant (left) and Charles Bradlaugh (right).

These two were atheists—a scandalous position at the time!—and they wanted to promote free-thinking about practically everything that upset the puritanical society of their time. Image
They were on trial because they tried to sell a book entitled Fruits of Philosophy.

This was an American guide to tons of different aspects of family planning, and included birth control methods, some of which worked, others which did not.Image
