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

How well-known is this?

A lot of the major pieces of civil rights legislation were passed by White elites who were upset at the violence generated by the Great Migration and the riots.

Because of his association with this violence, most people at the time came to dislike MLK. Image
It's only *after* his death, and with his public beatification that he's come to enjoy a good reputation.

This comic from 1967 is a much better summation of how the public viewed him than what people are generally taught today. Image
And yes, he was viewed better by Blacks than by Whites.

But remember, at the time, Whites were almost nine-tenths of the population.

Near his death, Whites were maybe one-quarter favorable to MLK, and most of that favorability was weak. Image

The Pope, like his recent predecessors, is good to take this position: anti-Semitism is manifestly idiotic!

On that note, did you know that the Catholic Church was actually one of the biggest forces in stopping the rise of the Nazis?

It's true!đź§µ Image
You might say that the Catholics didn't vote for the Nazis because they had their own party: Zentrum.

This isn't the explanation.

Note: the Catholic Church opposed both forms of totalitarianism in Germany, but it had an asymmetric effect against the Nazis, not the Communists.Image
The real "Catholic effect" on far right vote shares was small.

In reality, Catholics only became poised against the far right when the church began to actively campaign against it.

But when the local clergymen were "Brown Priests" (Nazi-supporting priests) like Alois Hudal? Image

The researcher who put together these numbers was investigated and almost charged with a crime for bringing these numbers to light when she hadn't received permission.

Now we have an update that goes through 2020!

First: Where are Sweden's rapists from?

Mostly not Sweden. Image
What countries were those foreign rapists from?

We only got information on the top five origins, constituting roughly half of the foreign-born samples, and thus about a quarter of all the rapists. Image
What about welfare usage? 35.1%.
Alcoholism? 14.9%
Drug addiction? 23.7%
A diagnosed psychiatric disorder besides that? 13%

What about a criminal prior? 52%. That compares to 13.4% of non-rapist criminals. So rapes? Considerably more preventable.

Greater Male Variability rarely makes for an adequate explanation of sex differences in performance.

One exception may be the number of papers published by academics.

If you remove the top 7.5% of men, there's no longer a gap! Image
The disciplines covered here were ones with relatively equal sex ratios: Education, Nursing & Caring Science, Psychology, Public Health, Sociology, and Social Work.

Because these are stats on professors, this means that if there's greater male variability, it's mostly right-tail
Despite this, the very highest-performing women actually outperformed the very highest-performing men on average, albeit slightly.

The percentiles in this image are for the combined group, so these findings coexist for composition reasons. Image

One of the issues with understanding Greater Male Variability on IQ tests is that groups that perform better tend to show greater variance

Therefore, to estimate the 'correct' male-female gap, you need to estimate it when the difference is 0

In the CogAT, that looks like this: Image
In Project Talent, that looks like this: Image
And comparing siblings in the NLSY '79, that looks like this: Image

About a decade ago, a theory emerged:

If men do more of the housework and child care, fertility rates will rise!

Men have been doing increasingly large shares of the housework and child care.

Fertility is lower than ever.Image
In fact, they're doing more in each generation, but fertility has continued to fall. Image
The original claim, that men's household work would buoy fertility, was based on cross-sectional data that was inappropriately given a causal interpretation.

The updated cross-sectional data is as useful, and it affords no assurances about the original idea.

We should move on.
