BTW, re: the Congo in particular: the most common traditional type of fishing is basket fishing with woven funnels suspended in the rapids. You sure as hell better know how to swim if you want to do that.

Famous angler Jeremy Wade referred to the local Congo fishermen as nearly suicidal, just diving into the rapids to get nets unstuck and the like.

SIGH.

There were 10 people chosen and people with dark skin in the USA make up about 1 out of 8 Americans.

1 in 8 is 12,5%.

African-American without mixed race in 2024 is estimated at 46,3M, or 14,2%
With mixed race, that rises to 51,6M, or 15,8% of the population.
Some hispanics have dark skin, some light. In 2023 there were 62,5%, representing 19% of the population (though there's a small overlap with black - doesn't affect the numbers much).
In 2023, Asians were 25,8M people, or 7,7% of the population. This is again a diverse group with mixed skin tones (for example, the Indian subcontinent)
In 2023, there were 1,6M people (0,49%) of pacific island ancestry and 3,3M native Americans - again, mixed skin tones.
People of Mediterranean European ancestry often have so-called "olive" complexions.

With a strict definition of dark skin, you're probably talking like 1 in 6 or so (~16,7%). With a looser definition, you could be talking upwards of 40% or more of the population.

The chances of the 10 people to be a perfect representation of the racial demographics of the USA is quite small.

Here are the actual odds of selecting no dark-skinned people at different population percentages being "dark skinned", by one's definition of "dark":

15%: 1 in 4
20%: 1 in 8
25%: 1 in 17
30%: 1 in 34
35%: 1 in 73
40%: 1 in 165

Then consider that NASA astronauts are required to pass a swimming test

It is not a test of swimming prowess, just of an ability to not drown. You have to be able to do three lengths of a 25-meter pool without stopping, three lengths of the pool in a flight suit and tennis shoes, and tread water for 10 minutes while wearing a flight suit. This is not some massively imposing task. You don't have to be Michael Phelps to become an astronaut.

and as a general rule those with African ancestry tend to have less stamina in swimming than those with lighter skin

Yes, white athletes tend to have an advantage in swimming. A 1,5% advantage. While a 1,5% advantage may be of good relevance at the highest level of a sport, it's hardly meaningful in a "can you tread water with a flight suit on" test.

Think of the different races as just really big families

That is not how genetics work, and is instead the pseudoscience that drove fascist movements, and in particular, Nazism.

There is far more genetic diversity within a given "race" than between them. Certain genetic traits tend to have strong correlates - for example dark skin and sickle cell anemia - but that's not because races are some sort of genetic isolates, but rather for very practical reasons (dark skin is an adaptation to not die of skin cancer in the tropics, and sickle cell disease is a consequence of a genetic adaptation to not die of malaria which also happens to be found in such climates). But the vast majority of genes don't have such strong correlates.

The concept of "race" as a distinct biological category is not supported by modern genetics.

If we are to ignore skin color and just put one big family up against another big family on swimming ability then just due to random mutations, perhaps some Darwinian selection way back in the family tree, one family will swim better than the other

The main "racial difference" in swimming ability in the US is "inherited", that is, parents who don't know how to swim tend to not teach their kids how to swim. As a result, white children are 56% more likely to receive swimming lessons than black children. One can expect that to directly correspond to an advantage in adulthood. But again, the ability to tread water is not out there knocking 90% of astronaut candidates out of the race - especially given that astronaut candidates tend to be athletic and motivated to learn new skills.

People with light skin tend to have ancestors that had to go fishing for their protein

Utter tripe. Fish consumption has no correlation with skin colour. How much fish do you think your average herder or plains horseman ate? And fish is massively important in much of Africa - in coastal areas (Gabon, Ghana, Sierra Leone in particular note), along the Congo (it's literally the world's largest river, people have been fishing it since time immemorial), Lake Victoria, Lake Chad, the Niger Delta, etc etc. What sort of racist stereotype world are you living in where black people don't fish?

Having a large candidate pool relative to the number chosen makes it easier to show bias and still get high-quality candidaes, not harder.

I dunno. China is a "market socialist" system -- which is a contradiction in terms. If China is socialist, then for practical purposes Norway and Sweden have to be even *more* socialist because they have a comprehensive public welfare system which China lacks. And those Nordic countries are rated quite high on global measures of political and personal freedom, and very low on corruption. In general they outperform the US on most of those measures, although the US is better on measures of business deregulation.

EVs would be residential, not wholesale, pricing.

Big AI Data Centers would be wholesale pricing.

It makes no sense to claim Chinese courts have a lot of power, although it may seem that way â" itâ(TM)s supposed to seem that way. One of the foundational principles of Chinese jurisprudence is party supremacy. Every judge is supervised by a PLC â" party legal committee â" which oversees budgets, discipline and assignments in the judiciary. They consult with the judges in sensitive trials to ensure a politically acceptable outcome.

So it would be more accurate to characterize the courts as an instrument of party power rather than an independent power center.

From time to time Chinese court decisions become politically inconvenient, either through the supervisors in the PLC missing something or through changing circumstances. In those cases there is no formal process for the party to make the courts revisit the decision. Instead the normal procedure is for the inconvenient decision to quietly disappear from the legal databases, as if it never happened. When there is party supremacy, the party can simply rewrite judicial history to its current needs.

An independent judiciary seems like such a minor point; and frankly it is often an impediment to common sense. But without an independent judiciary you canâ(TM)t have rule of law, just rule by law.

Hereâ(TM)s the problem with that scenario: court rulings donâ(TM)t mean much in a state ruled by one party. China has plenty of progressive looking laws that donâ(TM)t get enforced if it is inconvenient to the party. There are emission standards for trucks and cars that should help with their pollution problems, but there are no enforcement mechanisms and officials have no interest in creating any if it would interfere with their economic targets or their private interests.

China is a country of strict rules and lax enforcement, which suits authoritarian rulers very well. It means laws are flouted routinely by virtually everyone, which gives the party leverage. Displease the party, and they have plenty of material to punish you, under color of enforcing laws. It sounds so benign, at least theyâ(TM)re enforcing the law part of the time, right? Wrong. Laws selectively enforced donâ(TM)t serve any public purpose; theyâ(TM)re just instruments of personal power.

Americans often donâ(TM)t seem to understand the difference between rule of law and rule *by* law. Itâ(TM)s ironic because the American Revolution and constitution were historically important in establishing the practicality of rule of law, in which political leaders were not only expected to obey the laws themselves, but had a duty to enforce the law impartially regardless of their personal opinions or interests.

Rule *by* law isnâ(TM)t a Chinese innovation, it was the operating principle for every government before 1789. A government that rules *by* law is only as good as the men wielding power, and since power corrupts, itâ(TM)s never very good for long.

I guess I should clarify. In addition to "just the W2" there's also a monthly, quarterly, or yearly payroll tax report that goes to the IRS, along with a whopping large check for the withholding, as part of normal payroll processing. Different companies do different reporting standards, of course. But they're getting the data a lot more often than you think, just from the money paid in *during* the year, before the return is filed for.

#2 is already happening, that's what the Internal Revenue Service *does*.

50% revision from a survey is not consistent or predictable.

But we do know the answers- just use the information reported to the IRS from every employer doing business in the United States instead.

Maybe we shouldn't need to report the same data to multiple agencies? Estimated taxes, 1099s, and W2 information is already available from the IRS. You don't need to "survey" anybody, you can get down to the penny reads on the entire economy.

Class 1 and 2 e-bikes limit assist to 20 mph, not 15. You can ride them faster than that, but you have to provide the power. 20 mph is well above what most recreational cyclists can maintain on a flat course, so if these classes arenâ(TM)t fast enough to be safe, neither is a regular bike. The performance is well within what is possible for a fit cyclist for short times , so their performance envelope is suitable for sharing bike and mixed use infrastructure like rail trails.

Class 3 bikes can assist riders to 28 mph. This is elite rider territory. There is no regulatory requirement ti equip the bike to handle those speeds safely, eg hydraulic brakes with adequate size rotors. E-bikes in this class are far more likely to pose injury risks to others. I think it makes a lot of sense to treat them as mopeds, requiring a drivers license for example.

Would treating them as mopeds be so bad?

What weâ(TM)re looking at is exactly what happened when gasoline cars started to become popular and created problems with deaths, injuries, and property damage. The answer to managing those problems and providing accountability was to make the vehicles display registration plates, require licensing of drivers, and enforcing minimum safety standards on cars. Iâ(TM)m not necessarily suggesting all these things should be done to e-bikes, but I donâ(TM)t see why they shouldnâ(TM)t be on the table.

I am a lifelong cyclist , over fifty years now, and in general I welcome e-bikes getting more people into light two wheel vehicles. But I see serious danger to both e-bike riders and the people around them. There are regulatory classes which limit the performance envelope of the vehicle, but class 3, allowing assist up to 28 mph, is far too powerful for a novice cyclist. Only the most athletic cyclists, like professional tour racers, can sustain speeds like that, but they have advanced bike handling skills and theyâ(TM)re doing it on bikes that weigh 1/5 of what complete novice novice e-bike riders are on. Plus the pros are on the best bikes money can buy. If you pay $1500 for an e-bike, youâ(TM)re getting about $1200 of battery and motor bolted onto $300 of bike.

Whatâ(TM)s worse, many e-bikes which have e-bike class stickers can be configured to ignore class performance restrictions, and you can have someone with no bike handling skills riding what in effect is an electric motorcycle with terrible brakes.

E-bike classification notwithstanding, thereâ(TM)s a continuum from electrified bicycles with performance roughly what is achievable by a casi recreational rider on one end, running all the way up to electric motorcycles. If there were only such a thing as a class 1 e-bike thereâ(TM)d be little need to build a regulatory system with registration and operator licensing. But you canâ(TM)t tell by glancing at a two wheel electric vehicle exactly where on the bike to motorcycle spectrum it falls; that depends on the motor specification and software settings. So as these things become more popular, I donâ(TM)t see any alternative to having a registration and inspection system for all of them, with regulatory categories and restrictions based on the weight and hardware performance limitations of the vehicle. Otherwise youâ(TM)ll have more of the worst case weâ(TM)re already seeing: preteen kids riding what are essentially electric motorcycles that weigh as much as they do because the parents think those things are âoebikesâ and therefore appropriate toys.
