In 1942, the U.S. government forcibly removed more than 110,000 ethnically Japanese people from their homes and sent them to internment camps in remote parts of the country.
People are resilient, but losing everything is hard.
How did victims' lives turn out?🧵
First, we need background.
Japanese citizens began arriving to the U.S. in the latter part of the 19th century.
The scale of migration was substantial. By 1942, 40% of Hawaii was Japanese (Hawaii wasn't a state until 1959).
This influx of immigrants quickly became a political problem.
1886-1911, more than 400,000 Japanese set out to American lands. Citizens called for an end, resulting in the Gentleman's Agreement of 1907:
The U.S. wouldn't harass its Japanese and Japan would restrict emigration.
Immigration from Japan was cut down to virtually nothing from 1924 to 1952, creating a "missing generation" of people and distinguishing the first-generation "Issei" from their American-born "Nisei" children.
By 1940, Hawaii had 160,000 or so Japanese residents and the U.S. proper (recall, Hawaii was not a state) had an additional roughly 120,000.
As you can see, the largest portion of them were in California, in both Census and interment camp-derived figures.
On December 7th, 1941, Japan attacked Pearl Harbor, resulting in the deaths of 2,008 sailors, 109 Marines, 208 soldiers, and a further 68 civilians and ten others, along with the destruction of almost 200 aircraft, four battleships, and more.
With Japan's declaration of war, Issei transformed into enemy aliens on U.S. soil.
The first governmental response was for the FBI to start rounding up community leaders, resulting in the detention of 222 Italian, 1,221 German, and 1,460 Issei men that month.
The Ni'ihau Incident that happened after the bombing of Pearl Harbor also started to cement into American's minds the problem of enemy aliens.
Shigenori Nishikaichi crash landed his Zero after the attack and two Japanese island residents agreed to help him.
The Haradas (an Issei couple) and Ishimatsu Shintani helped Shigenori get his equipment + papers + torch his plane while kidnapping three native Hawaiians
The Hawaiians fought back. They killed Nishikaichi, Yoshio Harada killed himself, and Shintani and Yoshio's wife were caught
Around that time, FDR and Attorney General Biddle made statements calling for Americans to respect the rights of minorities including enemy aliens.
But shortly after that on February 19, FDR signed Executive Order 9066, allowing the military to set up exclusion zones.
The EO didn't specify anything for Japanese Americans, but it didn't have to, because Japan was busy frightening American civilians and military personnel.
On February 23rd, Japan bombed an oil field near Santa Barbara.
From November 1944 to April 1945, the Japanese had been launching Fu-Go balloon bombs that ended up dropping incendiary munitions in California and fourteen other states.
The Japanese also attacked a baker's dozen U.S. ships off the California coast.
Americans were so afraid of a Japanese invasion that they inflicted damage on themselves in the "Battle of Los Angeles."
The fear was rightful: The Japanese had subs 20 miles from California on December 24, 1941 and California only had sixteen modern airplanes protecting it!
Leveraging the powers granted by the EO, the military split the West Coast into two military areas and began distributing signs encouraging Japanese people to go East.
The voluntary migration scheme failed and the War Relocation Authority was set up to administer ten camps scattered across the U.S., for 110,000 Japanese Americans living on the West Coast
These relocated people had to get out quickly, selling possessions at "fire sale" prices
It's from this background that the analysis begins:
Arellano-Bover used Census, Japanese-American Research Project, and War Relocation Authority data to identify interned Japanese Americans so data on their socioeconomic outcomes could be put to use.
If we look at home ownership after the war, we see that the interned Japanese were definitely negatively impacted:
In the period 1946-52, they had significantly lower homeownership rates than Japanese Americans who weren't interned.
But look at 1953 to the '60s. Recovery?
Homeownership is about an asset. If we look at income data, we actually see that the Japanese who would go on to be interned had lower incomes than the non-interned Japanese in 1940, and equal incomes by 1950-60.
So the internment... raised incomes?
The answer to this seems to be "Yes."
Not only did the Japanese who were interned recover, they caught up despite starting further behind the Japanese who weren't interned.
This result is actually very robust!
So we have to ask Why?
Let's check attitudes towards work.
Bupkes. The interned and non-interned Japanese don't differ in work attitudes, so they couldn't get ahead that way.
What about attachment to Japan and Japanese culture?
Sansei (third-generation Japanese) were just as likely to have Japanese-speaking grandparents and citizenship/Americanness-wise, if anything, the interned were a bit less American.
This probably isn't it either.
Here's the meat:
In 1940, Japanese on the West Coast were disproportionately likely to be farmers and unskilled laborers, whereas the Japanese who migrated East and were thus less likely to be interned worked more often in skilled occupations.
This migration-related occupational stratification must not have been very selective by ability, because the interned/non-interned converged.
They also converged, in part, because the interned used the experience to move and change jobs.
The camps had more socioeconomic diversity than the places internees came from, so they were exposed to a diversity of opportunities and their family ties binding them to certain occupations were broken.
There were frictions the camps help them to overcome!
It was common to hear stories about internees entering poor and vowing to make it big when they got out, like this pictured one.
And that's what they did: interned Japanese Americans overcame the experience and wound up, miraculously, better off for it.

The Reich Lab article on genetic selection in Europe over the last 10,000 years is finally online, and it includes such interesting results as:
- Intelligence has increased
- People got lighter
- Mental disorders became less common
And more!
They've added some interesting simulation results that show that these changes are unlikely to have happened without directional selection, under a variety of different model assumptions.
They also showed that, despite pigmentation being oligogenic, selection on it was polygenic.
"[S]election for pigmentation had an equal impact on all variants in proportion to effect size."
I still think this is one of the most important recent papers on AI in the job market🧵
The website Freelancer added an option to generate cover letters with AI, and suddenly the quality associated with cover letters stopped predicting the odds of people getting hired!
LLMs do a few things to cover letters.
Firstly, they increase the quality, as measured by how well tailored they are to a given job listing.
Second, they make job applications in expensive, so people start spending less time shooting off applications.
More, rapidly-produced job applications becomes the norm.
Now, we have a breakdown of different types of rich people!
Among those who could be classified, the majority of the rich (79%; >=€1m net worth) were self-made, with a smaller, 21% share whose wealth came primarily from inheritances.
How do inheritors and the self-made differ in personality?
They're both more risk-tolerant and less neurotic than the average, but the inheritor profile looks like a mixture between the overall rich and normal people, with more agreeableness, less openness, etc.
Why have testosterone levels been rising over time?
The testosterone levels of American men are up compared to what they used to be, but no one has a good explanation.
Let's look through some possibilities🧵
Is it perhaps because of a racial composition change?
No.
Different races tend to have similar testosterone levels and trends within groups are similar.
Is it perhaps because of age composition change?
No.
The decline by age is much more graceful than people tend to suspect, and within each age group, levels are up without survey weighting, and in nearly all with it, they're still up.
In my latest article, I documented that the only RCT for functional medicine methods appears fraudulent🧵
Before getting into it, what's functional medicine?
It's a pseudoscience used to bilk patients by getting them on an unending cycle of tests, supplements, and more tests.
Functional medicine's practitioners claim that they can reveal and treat so-called "root causes" of people's health problems
These are proposed to be things like gut health, toxin burdens, and various chemical and hormonal imbalances
They find these things with unproven tests
If you run enough tests, you will be able to find something that looks 'off' about a patient, and if you're a functional medicine doctor, that's your 'A-ha!' moment, even if—as is usually the case—the result is just a false-positive and treating it is unlikely to do anything.
