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?

Comment Re:They can hide anything in the SEC reports, now (Score 1) 46

Indeed, I fully agree. The funny thing is, monthly numbers would help us move away from the distortions of the quarterly cycle. If key data reporting becomes frequent enough, you can't get into a cycle of "do adverse-numbers stuff early in the quarter and then cram positive-numbers stuff into the end of the quarter". You have to - *gasp* - just run your business normally.

Some businesses could still manage to switch to a monthly cycle, but anyone who deals significantly in transoceanic feedstocks/parts/goods shipments won't be able to.

BLS numbers aren't some sort of dark art. They're literally just the compiled numbers reported by companies. Numbers are what they are. To fight against jobs numbers is to fight against reality.

People get confused by the existence of revisions. The problem is that not all data gets reported in a timely manner. When late data comes in, it causes revisions to the earlier reported numbers, either up or down.

Firing the head of the BLS because you don't like what numbers US companies reported is just insane Banana Republic-level nonsense.

Yes, he fired the same person who was ultimately responsible for putting out crap numbers.

US reporting has always been the gold standard. Nobody has accused the BLS of "crap numbers" until Trump decided he didn't like them. It's is so way outside the norms it doesn't even resemble something that could conceivably happen in the US; this is banana republic-level stuff.

Comment Re: Can be paired with other energy sources (Re:He (Score 1) 82

Integrated thermal stores with nuclear is more difficult (limited temperatures and limited dT on storage = big storage needed with lots of heat exchange surface area), but if they can make it economical, it could be a game changer for nuclear's problematic economics. The ability of nuclear to switch from baseload (not matching the demand curve, let alone the curve of really-cheap renewables) to load-following and even peaking could make the mean sale value of its electricity much higher, and make it much more useful as a compliment to renewables.

Comment Re:Use in warmer climates (Score 1) 82

The mean July maximum temperature in Helsinki is 27,1C (80,8F), and the record is 33,2C (91,8F). Combine this with the fact that the interiors of large buildings accumulate internal heat. Cooling is of utility. Let alone for industry (most industry is fine with cooling with ambient water temperatures, but some needs cooling beyond that).
