The more interesting literature search might be rates of autoimmune diseases. And the intricate knot of separating change in detection rates from causal factors. Wiley is a good starting place... https://onlinelibrary.wiley.com/doi/10.1111/1756-185X.15426

Id say it's a question of practical ethics - how do societies stuff genies back into the bottles? Scientists can't generally claw back the tech consequences of their discoveries (a stern letter from Einstein or Fermi would not have stopped nuclear weapon development). And technologists are, like most people, needing a paycheck and inclined to rationalize their participation in the process. So that leaves...(Holds nose, suppresses gag reflex)...political solutions combined with global treaties. Things like the Megatons to Megawatts treaty were a start. Or the major legal and political victories against PFAS, which hopefully will continue. Ethical solutions on such technologies will be slow painful and ugly processes in courts and legislative chambers. Thanks to the extremely thick skulls of many in legislative chambers, incidents of massive death will probably take place before they awaken to some of these problems. Others are just corrupt, and that will mean getting corporate money out of political campaigns. Possibly, we're all f--ed.

Could be useful for new options for C sequestration, too. Peridotite is a good C02 absorber. Carbonates formed. MIT Technology ReviewCarbon-Capturing RockGeologists discover that certain rock formations could sequester large amounts of carbon dioxide. Anything that adds to our knowledge of element cycling between biosphere and asthenosphere is pretty important right now.

My wife is the music director for her church, and occasionally deals with Gregorian chants in the square-shaped neumes. Mainly for antiphons. But she converts to modern notation to them print them off. I guess neumes have ways to sorta imply rhythm, but standard notation makes it easier for her congregation. Chant, if I understand it, being unmetrical has rhythm loosely defined or implied by the words of Latin text (and basically, in her church, by watching the lady's hand gestures). Or they use Solesmes method. In any case they use a fluid and flexible lengthening of equal note values as chant calls for. I'm impressed at how a choir can achieve that fluidity so well in synch.

Can make neither head nor tail of this. What does "speed of light of the universe" mean and how is this different from the speed of light? Aren't we part of the universe? Isn't C a constant?

I am uncertain on this seeming paradox (the kind normally encountered in a story from Connie Willis' Oxford Time Travel Series), since I don't login to YT or use their app. It is possible that someone using the app can easily access a history list through their settings menu (which I think, in the app, you access by clicking on your face icon?). When I use it, anonymously and on the web, I sometimes encounter your problem, the same search yielding different results. The web version still gathers the history somehow, and then misguidedly "thinks" you'd like something a little different this time. Unless you deactivate history - then it will not react to your device address or anything in some sort of cache. One way out of this morass is toa just use the clipboard. The clipboard will store that URL as long as you want provided you use the pin option. Assuming you have something comparable to Chrome's clipboard.

YT has a setttings menu. You can shut off watch history. In theory, this would enable a duplicate result of a previous search. IIRC you click on the little gear icon and select Manage History.

Non culture biased cognitive tests for anyone running for high office (or cabinet appointees), and notably more rigorous than "I could read the teleprompter at Fox News, and memorize cocktail recipes easily..."

I wasn't sure what xenog was short for, unless it was xenogenesis, as in the Octavia Butler novels. Which would be, at this point, ironic given Butler's ethnic origins. Anyway, one can actually use your hillbilly reference to observe that no one has come up with a conjecture that rural folk of Scots-Irish descent in Appalachia have consistently shown lower IQ scores for many generations due to their ethnic origins. Funny how that works, eh? Please cite your sources for claiming fluid intelligence is not influenced by such interventions. This is not what I have seen. Especially where we are talking of early pre-K learning options. This is the fallacy of Argument from Incredulity. Many systemic biases have persisted long after legal/political remedies were put in place. See my comment about Appalachia. Long persisting lower scores there haven't led you or anyone else to posit a genetic lower intelligence in Scots-Irish and English ancestry. Hmm.

I was often Bob. Except one evening when I tried tequila. In the US, the rum baba is often served as rum-raisin baba (as if it weren't already sweet enough). This led to a National Lampoon magazine character (1970s) named Baba Rum Raisin, who was a satirical version of Baba Ram Dass, a popular guru who was born Richard Alpert, and was a Harvard colleague of Timothy Leary in his consciousness research. A chat which starts at Terry Riley and arrives at Timothy Leary has definitely circled back on itself. 😁

Out here in the fields, we fight for such meals.

Heh. Ah yes, the old minor triad major seventh matchup. I play that when the spouse walks in the door while I'm practicing. If she then pokes me in the ribs, I offer a lower register tritone. Hadn't heard "berserker" applied to C11, but it is pretty dissonant if you don't take the third out. It's the Cadd9 (CEGD) that's more bright and open and nicknamed a heaven chord. If you leave the Bb in there, straight C9, it's bluesier. More Leonard Coheny. Too complex for Heaven I'd imagine. 😉

https://onlinelibrary.wiley.com/doi/abs/10.1002/ajpa.24216 American Journal of Physical AnthropologyVolume 175, Issue 2 pp. 465-476 AbstractObjectivesDebate about the cause of IQ score gaps between Black and White populations has persisted within genetics, anthropology, and psychology. Recently, authors claimed polygenic scores provide evidence that a significant portion of differences in cognitive performance between Black and White populations are caused by genetic differences due to natural selection, the “hereditarian hypothesis.” This study aims to show conceptual and methodological flaws of past studies supporting the hereditarian hypothesis. Materials and methodsPolygenic scores for educational attainment were constructed for African and European samples of the 1000 Genomes Project. Evidence for selection was evaluated using an excess variance test. Education associated variants were further evaluated for signals of selection by testing for excess genetic differentiation (Fst). Expected mean difference in IQ for populations was calculated under a neutral evolutionary scenario and contrasted to hereditarian claims. ResultsTests for selection using polygenic scores failed to find evidence of natural selection when the less biased within-family GWAS effect sizes were used. Tests for selection using Fst values did not find evidence of natural selection. Expected mean difference in IQ was substantially smaller than postulated by hereditarians, even under unrealistic assumptions that overestimate genetic contribution. ConclusionGiven these results, hereditarian claims are not supported in the least. Cognitive performance does not appear to have been under diversifying selection in Europeans and Africans. In the absence of diversifying selection, the best case estimate for genetic contributions to group differences in cognitive performance is substantially smaller than hereditarians claim and is consistent with genetic differences contributing little to the Black–White gap. A couple points: One, please provide citations rather than "what I recall reading," as our forum rules require you to do when requested. We need to see the data you're seeing and how it's being interpreted. Two, twin studies are prone to sloppiness in isolating causal factors. Adopted children generally, for example, receive somewhat differential treatment from biological children in a given family no matter how good the parental intentions or the degree of wealth. There can also be overseas effects for children adopted into richer Western families, where a shift in various environment features in the first year or two of life (ambient allergens or pathogens, for one) can affect the child's development. This is shifting the goal posts. No one has argued that environment is the sole determining factor. G comes from an interaction between many gene variants and the environment. The issue is whether genes are significant in differences in G between human groups. DNA analysis has found hundreds of genetic variants that each have a very tiny association with intelligence, but even if you add them all together they predict only a small fraction of someone’s IQ score. And heritability, whether low or high, implies nothing about modifiability. The classic example is height, which is strongly heritable (80 to 90 percent), yet the average height of 11-year-old boys in Japan has increased by more than 5 inches in the past 50 years. A similar historical change occurs for intelligence.

I knew a psych professor who liked to say "halo effects are everywhere." People frequently observe traits they like and make dubious correlations with general intelligence. And video culture can promote such halo effects, causing (often unconscious ) mental associations between certain phenotypes and cognitive skills.

Relating back to solipsism, I find that great music offers a profound rebuttal to solipsism (not like it needs one, but having that on a deep emotional level is something). Funny how you scratch the surface of a science forumite and so often find a poet and/or musician. (Jazz improviser here) A poet like Shelley can use words that are about certain feelings and intuitions, but where we go from that is beyond those words. Music can also be about something but it can also just be something. In that case, the art IS the experience rather than about or reflecting experience. Is a C9 chord "heavenly," as some say, i.e. is it about heaven? No it just is - the experience is what it is. You're not reproducing some other experience, you're just having one. (Ok, wildly off topic and I'm ready for my manacles, moderator)

Ok, there's the vagueness again. What precisely is meant by education? Generally, when the wealthy in Nigeria are, thanks to wealth, now providing childhood nurture at what are norms in the Western middle class, there is a broad palette of educational advantages beyond just larger vocabulary and better reading skills. The best schools that wealthy families afford would offer student projects and problem-solving tasks which would impact fluid intelligence as well as crystallized intelligence. And students, not having to go to dull repetitive laboring jobs or similar after school would better integrate those cognitive skills. Again, when these Nigerian women were raised with Western norms of access and education and nurture, their scores rose to parity. If there is ambition to emigrate, that's not a selective effect for IQ but for personality traits that may not relate to IQ at all. After all, if ambition and drive correlated closely with IQ, the current US government would look vastly different.

An assumption can still be correct even if some policies derived from that assumption are ineffective. And the assumption you mention is robustly supported by social science studies that look at how outcomes and disparities change when discrimination is lessened for minorities and outreach programs support childhood nurture. You haven't produced a shred of evidence that programs supporting things like nutrition, literacy, stable family life, healthy housing, arts after school, etc are "wrong-headed." And resorting to vague phrases like "social justice style" doesn't advance your position. It's just hand-waving. LOL.

2nd that. Seems to be a persistent ignoring of culture/nurture in this malodorous sidebar. LMAO. Ah, but those women are an elite group which means... oh wait...they experienced better nutrition and care and a richer stimulating learning environment in childhood and particular cultural emphasis on diligence and task persistence. You realize you are supporting the nurture side of the argument with these observations, right? These elites are getting the nurture environments which seem to bring them up to the functional levels common in wealthy nations. How are you missing this?

TIL why the Who song is called Baba O'Riley. Released October 1971, so it only took me 54 years to make the connection to the father of minimalist composition, Terry Riley. Once you hear A Rainbow in Curved Air, you realize the Who hommage in their most misreferenced song ( I've even heard a DJ misname the track as "Teenage Wasteland.")

Jesting about the "baby angels," as I'm sure you realized. Americans are notorious for their cultural tendencies towards sleep deprivation. The bit about biphasic sleep is interesting, and something my historian partner has delved into. I am inclined that direction myself, and will often split my sleep cycles now that I'm retired. One pleasure of the biphase night is remembering dreams better. Well, who doesn't enjoy watching the battleships as they glide into their docks?

On road today, can't type much on this device, so my thanks for your post cutting to the heart of this tiresome race mythology. And to @CharonY too for reminders of the pitfalls of the statistical data.

Dim's comments sometimes tend to be more poetic than well-researched. Where are these homes with people sleeping 8-10 hours that you speak of? Do such homes offer adoption programs? Are these residents like baby angels raised by puppies in a beachfront palace with no right angles? Light teasing aside, it seems like routines make considerable difference in the overnight fasting period. Breakfast, as a zeitgeber, seems malleable. Though most people who try shifting to a brunch, moving the fast from twelve hours to sixteen, say, will hit a fairly hard wall at some point. While I benefit from my 16 hour hiatus, it didn't come easily, and I really need to find some food by 10-11 am.

We don't, actually, because this is a science forum not a Far Right garbage conspiracy theories forum. White males who get demoralized because brown people and women turned out to be smart at science too are responsible for their own biases and mood disorders. If that causes them to stomp their feet and blow off study sessions, then maybe they're too fragile to do science. Best leave it to people who know how to work hard.

That's funny, I used the same phrase, mixed bag, on the SFC thread. Watson basically stole a Nobel from her, imo. Then slandered her after she died. It's pretty reprehensible and goes way beyond poaching from grad students.
