I suspect "The Sort" can greatly increase your exposure to time-wasting incompetence🧵 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

"What happened in 1971?"

Nothing, that's just a common year people choose to mismeasure productivity and pay series from🧵 Image
Using nonfinancial corporate sector productivity and wages, we see the same picture indicating no stark divergence in 1971. Image
Simply using value-added and total compensation for the nonfarm business sector, you get a similar picture. Once again, 1971 is not special. Image

Massachusetts residents who go to vote this November are going to see a curious ballot initiative:

Repeal Competence Assessment Requirement for High School Graduation.

The initiative is being championed by Progressives opposed to standardized tests.

Let's discuss🧵Image
Firstly, who's sponsoring this initiative?

The officials are @SenWarren @RepMcGovern @AyannaPressley @RepLoriTrahan and @JimHawkins4Rep.

The unions are the MA AFL-CIO and the Teachers Association.

The organizations are MassVote and Progressive Massachusetts.
And what are their reasons?

The official website says having a high-stakes test as a graduation requirement is "ineffective" and "discriminatory". Discriminatory against whom?

(1) Non-Whites, (2) people who don't know English, and (3) people with learning disabilities. Image

These journalists may not know it, but the Floyd Effect is real.

You can see the causal impact of George Floyd's death on homicide rates extremely clearly using data provided by the CDC. Image
Q: How?

A: Probably a lot of things, including police 'backing off' from criminal enforcement.

Q: Isn't this just COVID?

A: No. The increase occurs in the month Floyd died, not the month COVID set in or lockdowns were called. Moreover, this does not appear outside of the U.S.
We can see the CDC's estimates replicated in FBI NIBRS data, but we have to caveat this because the data is lower-quality.

For one, the Decembers include full-year reports for many agencies, so we'll toss them. Same prob. other mo's🤷‍♀️. For two, much of the 2021 data is missing. Image

In the U.S. and even Europe, smarter people are more likely to found businesses and for their businesses to succeed.

But in China, smarter people are actually less likely to start businesses🧵Image
To be sure, in China, scores on the Gaokao are related to company performance.

The smarter the founder, the more likely the firm is to expand, to get out of its founding province, to become listed on a stock exchange, and so on. Image
The smartest kids in a school also produce businesses that are more likely to survive for a long time. Image

This is an ice core from West Antarctica. The black ring on it is a layer of volcanic ash deposited some 21,000 years ago.

This and other ice cores can help us to learn about the past, including Phoenician and Roman history🧵 Image
As it happens, lead emissions can be measured in ice cores (green), peat bog coring sites (cyan), and lake sediment, among other options.

This map shows the sensitivity of the ice-core record to historical northern hemisphere atmospheric lead emissions. This will be important. Image
The ice in Greenland provides us with a nearly-contiguous record of annual average lead emissions for long periods of history. Image

OK, this is just absurd now. The Biden-Harris administration has attacked three emergency services agencies in a week because apparently these exams are too hard for Black people.

Want to see how hard this exam is? Let's look at some questions.

First up: Image
For the next two questions, you'll have to use the following information that you can reference at any time during the test: Image
Now can you... do basic addition and subtraction?! Image
