I suspect "The Sort" can greatly increase your exposure to time-wasting incompetenceđź§µ Image
The obvious example of how The Sort exposes you to incompetence is that nowadays, competent people don't go into the public sector all that often.

This is a mixed bag: while the government is a poor use of human capital, it needs some to avoid holding back the rest of society.Image
There are also a lot of fairly menial service sector jobs that you'll run into all the time, and these are less obviously, but no less problematized by The Sort. Image
Why? Because in the past, socioeconomic status was less cognitively stratified.

You can still see this today in many developing economies, where intelligence is slowly becoming more related to socioeconomic status as markets develop and opportunity expands. Image
The improvements to The Sort mean that fewer and fewer smart people are born into and remain in bad conditions.

But that also means that fewer and fewer smart people spend a long time in menial service sector jobs. Image
Accordingly, the quality of the work in those jobs is worse than if the job had more intelligent people working it.

Why? The first reason is that smarter people just do jobs better: They make fewer mistakes, operate more efficiently, often even have higher moral standards, etc. Image
The second reason is that, because smart people do jobs better, they teach less smart people how to do the job better, either directly or by example.

When you have more and less intelligent people play games, combining them brings up the less able.

In effect, many jobs are becoming more and more of left tail-exclusive jobs, with the effect being that they're done worse and worse, making your life harder and wasting more of your time when you run into them.

But it doesn't have to be this way!
Ever been to a Buc-ee's?

They're Texas' amazing gas station/car wash combo stores, and they're known

(A) Being pleasant, and

(B) Very publicly paying their employees well. Image
If you've been to a Buc-ee's you might have noticed that they offer discounted gas if you wash your car.

Their car washes are very long and the wait times are minimal compared to other offerings.

They have minimal human involvement.Image
Because Buc-ee's embraces productivity-improving tools and builds, and pushes their employees to be efficient, they can afford to pay them well and to pass on lots of savings to customers, and they also pass on saved time over other car washes.
Productivity enhancements that eliminate the involvement of human labor have the opportunity to cut out increasingly-inefficient human components of jobs.

If the carwash is nearly fully automated, the wages can be respectable and slow' human involvement can be minimized.
And where will the people currently working those jobs go?

Take manufacturing employment. When industrial robots are installed, employment goes down in that area, but up more in non-manufacturing jobs.

The disemployed move jobs. Source: https://library.oapen.org/handle/20.500.12657/55791
Wages tend to go up. They tend to move to better jobs, or at least jobs that are less dangerous, less monotonous, and which are better compensated.

And crucially, that left tail? It might move closer to the rest of the cognitive pack, meaning its members can skill up.
Automation might be even more of an engine of progress and life improvement than people generally assume, and it might make all of our lives better off by fixing some of the downsides of The Sort.

Thanks, robots! 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!

The CDC's new Advisory Committee on Immunization Practices (ACIP) didn't put out immunization guidance for 2025-26.

So some researchers got together and did the government's job for them. Here's what they foundđź§µ

First, the RSV vaccine is great for preventing hospitalization! Image
The next thing up is the flu vaccine.

These are still showing a touch lower efficacy than in previous years, but they're still

(1) good
(2) worth it
(3) even more worth it for infants and children Image
Then we have the COVID vaccines, which still seem to be useful enough to save a lot of lives.

These are also still better for the old.

That's good! Image

How rich are American workers?

Very!

After accounting for taxes, transfers, cost of living differences and so on, American workers make far more than their counterparts across the OECD. Image
Is this just because Americans work more?

No. That has something to do with it for some comparisons, but it's not everything.

Americans are also more productive and they get to take home more of what they earn. Image
This is an update on the 2021 numbers I previously presented here: x.com/cremieuxrecuei…, x.com/cremieuxrecuei…, x.com/cremieuxrecuei…

When we have 2024 numbers or later numbers, I'll update to those. But we have to wait on the OECD to release that data, so until then, enjoy!

Here's the old style plots if you want those:Image

Wow!

Across basically all of Europe, people at higher income levels are now *more likely* to become parents!

This is a stunning shift! Image
Among men, this relationship goes a while back now, and in several places, the income gradient has gotten more extreme. Image
Among women, there are some recent crossover events, where the low-income used to be more likely parents than the rich, but now it's different. Image

Wolf packs are remarkably good at respecting each other's established borders. Image
The project this data is from sometimes releases videos of how this plays out.

For example, here's a video of this playing out for a few wolves over a single day in Spring.
Alternatively, about 10-20% of wolf populations lack a pack. They're "lone wolves" and they're more likely to just wander across the territory of different packs

But this isn't permanent! Apparently this one eventually joined a pack and changed his long-distance traveling habit!

Air traffic control has a major problem in the pipeline.

ATCs are underpaid and overworked.

99% of control towers were understaffed in 2023 and the number of communication mishaps and near-misses between commercial aircraft skyrocketed.

I think the solution might be dronesđź§µ Image
You might think: Wait, haven't drones been smashing into planes recently? How are they going to help?

That's true! I've attached some pictures of drone-related damage. It's real and getting worse, I'll give you that.

The answer lies in drone communication.Image
Image
Image
Image
Drones don't yet, but they can start to, constitute a low-level communication and monitoring layer around airports and other protected airspace.

Drones can relay information about the locations of other drones, obstacles, incoming planes, and so on. Image
