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

There's a popular belief that family wealth is gone in three generations.

The first earns it, the second stewards it, and the third spends it away: from shirtsleeves to shirtsleeves in three generations!

But how true is this belief?

Gregory Clark has new evidenceđź§µ Image
The first thing to note is that family wealth is correlated across many generations. For example, in medieval England, this is how wealth at death correlates across six generations.

It correlates substantially enough to persist for twelve generations at observed rates of decay: Image
But why?

The dominant theory among laypeople is social: that the wealth is directly transmitted.

This is testable, and the Malthusian era provides us with lots of data for testing. Image

The Catholic Church helped to modernize the West due to its ban on cousin marriage and its disdain for adoption, but also by way of its opposition to polygyny.

The origin of this disdain arguably lies with Church Fathers like Justin Martyr, Irenaeus, and Tertullianđź§µ Image
Justin Martyr, in his Dialogue with Trypho argues with a Jew that Christians are the ones living in continuity with God's true intentions.

Justin sees Genesis 2 ("the two shall become one flesh") as normative.

In his apologetic world, Christians are supposed to transcend lust.Image
Irenaeus, in Against Heresies, is attacking Gnostics (Basilides, Carpocrates), whose sexual practices he finds scandalous.

To him, "temperance dwells, self-restraint is practiced, monogamy is observed"—polygyny is a doctrinal and moral deviation from creation affirmation.Image

The effects of charter schools on student test scores are meta-analytically estimated to be small.

In this study, the largest estimated effect was estimated to be equivalent to ~1.35 IQ points, for mathematics scores, which consistently showed larger effects than reading scores. Image
Similarly, the estimated effect of parents' preferred schools and of elite public secondary schools on test scores is around zero. Image
More interestingly, it seems charter school openings lead to competition that marginally boosts non-charter student performance and reduces absenteeism by very small degrees:

Amazing!

The missing heritability issue between SNP heritability methods and traditional pedigree-based estimates has now shrunken to just 12%.

Thanks to large-scale whole-genome data and simultaneously estimated phenotypes, there's not much missing heritability left! Image
This analysis has several advantages compared to earlier ones.

The most obvious is the whole-genome data combined with a large sample size. All earlier whole-genome heritability estimates have been made using smaller samples, and thus had far greater uncertainty.
The next big thing is that the SNP and pedigree heritability estimates came from the same sample.

This can matter a lot.

If one sample has a heritability of 0.5 for a trait and another has a heritability of 0.4, it'd be a mistake to chalk the difference up to the method.

This policy change has resulted in liberal experts coming out of the woodwork to allege that the policy is...

Intended to discriminate against Hispanics and Indians!

This one even alleged that this is discrimination on the basis of genetic race differences!Image
Trump deserves some praise for getting people to fess up to their hereditarian views on this matter.

Also, frankly, the policy is reasonable.

No fat people, no psychos, no sick people who will be burdens.

The only exception should be for those *paying for treatment here*. Image

Here are some choice Watson quotes to think about.

"I wouldn't have married a gum-chewing vegetarian." Image
Just being correct: Image
Left-wing nuts and environmental kooks are still noted screamers today. Image
