RFK Jr on ethnic allele frequencies

tl;dr: RFK Jr. asserted recently that "COVID-19 is targeted to attack Caucasians and Black people", while "the people who are most immune are Ashkenazi Jews and Chinese", also implying that this "racial and ethnic differential" means that the virus may have been created as an "ethnic bio weapon". In response to objections, he defended his assertion on the basis of total misrepresentation of a scientific publication, itself problematic. Details below…

"An exercise in inference sabotage"

Eve Armstrong, "I Murdered Conan O'Brien and Nobody Will Ever Know — an exercise in inference sabotage", 3/30/2023:

Abstract: I employ an optimization-based inference methodology together with an Ising model, in an intentionally ineffectual manner, to get away with murdering an obstreperous scientific collaborator. The antics of this collaborator, hereafter "Conan O'Brien," were impeding the publication of an important manuscript. With my tenure date looming, I found myself desperate. Luckily, I study inference, a computational means to find a solution to a physical problem, based on available measurements (say, a dead body) and a dynamical model assumed to give rise to those measurements (a murderer). If the measurements are insufficient and/or the model is incomplete, one obtains multiple "degenerate" solutions to the problem. Degenerate solutions are all equally valid given the information available, and thus render meaningless the notion of one "correct" solution. Typically in scientific research, degeneracy is undesirable. Here I describe the opposite situation: a quest to create degenerate solutions in which to cloak myself. Or even better: to render measurements incompatible with a solution in which I am the murderer. Moreover, I show how one may sabotage an inference procedure to commit an untraceable crime. I sit here now, typing victoriously, a free woman. Because you won't believe me anyway. And even if you do, you'll never prove a thing.

Extraterrestrial iron

Isaac Schultz, Gizmodo (12/20/22):

The Coolest Archaeological Discoveries of 2022

Let's revisit the best old stuff that made headlines this year.

Some of these are gruesome, e.g., the parasitic worms found in 2,700-year-old toilet, which reminds me of my experiences in Nepal.  Many of them have implications for language and linguistics (see the references and links below).  Most of them attest to cultural contacts across wide distances.

My favorite is King Tut's space dagger, made out of meteoritic iron, which is especially interesting, given that the Iron Age didn't begin until a century after King Tut's death.

The researchers did chemical analyses on the dagger and also turned to ancient Egyptian literature, where they found references to a special dagger gifted to King Tut’s grandfather by a foreign ruler.

"The psychology of thinking discretely"

Andrew Gelman, "The psychology of thinking discretely", 10/20/2022:

Sander Greenland calls it “dichotomania,” I call it discrete thinking, and linguist Mark Liberman calls it “grouping-think” (link from Olaf Zimmermann).

All joking aside, this seems like an interesting question in cognitive psychology: Why do people slip so easily into binary thinking, even when summarizing data that don’t show any clustering at all:

It’s a puzzle. I mean, sure, we can come up with explanations such as the idea that continuous thinking requires a greater cognitive load, but it’s not just that, right? Even when people have all the time in the world, they’ll often inappropriately dichotomize. I guess it’s related to essentialism (what isn’t, right?), but that just pushes the question one step backward.

As Liberman puts it, the key fallacies are:

1. Thinking of distributions as points;
2. Inventing convenient but unreal taxonomic categories;
3. Forming stereotypes, especially via confirmation bias.

Copper and tin: a reassessment of basic terms in ancient Chinese metallurgy

During the recent decade and more, we have had dozens of posts dealing with the importance of archeology for studying the spread of ancient languages.  A major subtheme of this research has been the accumulation and assessment of archeological and linguistic evidence for the dissemination of metallurgical technology (see "Selected readings") below.

A new study of an early Chinese text sharpens our understanding of key terms relating to the composition and smelting of bronze during the first millennium BC.  Here is a popular account of this pathbreaking investigation:

Infinitely malleable electronic brain — software and hardware

When I was a little boy, among the gifts from my parents that I treasured most were science kits that allowed me to construct my own instrumentation and use it for various experiments and observations, e.g., microscopes, radios and other electronic circuitry, chemistry sets, ingenious language games, and so on.  (This was in the late 40s and 50s in rural Stark County, northeast Ohio, mind you, when I was between the ages of about 5 and 15.)  But my favorite of all was a box full of materials for computer construction.  It consisted of a peg board, switches, wires, screws, small nuts and bolts, metal bands and clips, batteries, little light bulbs, etc.  Please remember that this was long before personal computers were invented.

Oil: a partial paradigm

Oil is one of the most important substances used by human beings.  It can be an essential food for consumption, a medium for cooking and frying, a lubricant, a material for the transmission of pressure through closed channels, a soothing substance for the skin, a substance to burn for propulsion and illumination, a polishing agent, and so forth.  It can even be used metaphorically and literally to signify a calming agent:

The figurative expression pour oil upon the waters "appease strife or disturbance" is by 1840, from an ancient trick of sailors.

Another historical illustration which involves monolayers, was when sailors poured oil on the sea in order to calm 'troubled waters' and so protect their ship. This worked by wave damping or, more precisely, by preventing small ripples from forming in the first place so that the wind could have no effect on them. [J. Lyklema, "Fundamentals of Interface and Colloid Science," Academic Press, 2000]

The phenomenon depends on what are called Marangoni effects; Benjamin Franklin experimented with it in 1765.*

Japanese periodic table versus Chinese periodic table

[This is a guest post by Conal Boyce.]

As they say, "a picture is worth a thousand words." Here are two pictures, copy/pasted from Google Images: First, the Japanese periodic table, then the Chinese periodic table. I apologize for the tiny font, but notice how, in the Japanese periodic table, the symbol 'S' has the word for sulfur (硫黄) under it. That pair of kanji, Romanized as iō, is simply an annotation of the international symbol, S, not meant to 'compete with' S. (Glance also at the very long katakana items that appear elsewhere, e.g., for the element Sc or Mt. The nuance that I'm driving at will become clear after you compare the Chinese periodic table further down, and see how S, Sc, and Mt are handled there. No need to know any Chinese or Japanese at all to see what's afoot here.)

'Case Studies of Peer Review'

Eve Armstrong, "The Three Little Pigs and the Big Bad Wolf: Case Studies of Peer Review":

Abstract: I present for your appraisal three independent cases of the manuscript referee process conducted by a venerable peer-reviewed scientific journal. Each case involves a little pig, who submitted for consideration a theoretical plan for a house to be constructed presently, in a faraway land. An anonymous big bad wolf was assigned by the journal to assess the merit of these manuscripts. The pigs proposed three distinct construction frameworks, which varied in physical and mathematical sophistication. The first little pig submitted a model of straw, based on the numerical method of toe-counting. His design included odd features, such as spilled millet and cloven-hoofprints on the window sill — possibly a ploy to distract the wolf from the manuscript's facile mathematical foundation. The second little pig used a more advanced approach, employing Newton's classical laws of motion, to propose a house of sticks. This pig included in her manuscript copious citations by a specific wolf, possibly aiming to ensure acceptance by flattering the wolf whom she anticipated would be the referee. The third little pig described an ostentatious house of bricks based on an elaborate dynamical systems and stability analysis, possibly scheming to dazzle and impress. The big bad wolf did not appear moved by any of the pigs' tactics. His recommendations were, for straw: the minor revision of water-proofing; for sticks: the major revision of fire-proofing, given concerns surrounding climate change; for bricks: unequivocal rejection, accompanied by multiple derogatory comments regarding "high-and-mighty theorists." I describe each case in detail, and suggest that the wolf's reports might be driven as much by self interest as the manuscripts themselves — namely, that at the time the wolf wrote the reviews, he was rather hungry. Finally, I examine morals learned, if any.

Tortured phrases: Degrading the flag to clamor proportion

Guillaume Cabanac, Cyril Labbé & Alexander Magazinov, "'Bosom peril' is not 'breast cancer': How weird computer-generated phrases help researchers find scientific publishing fraud", Bulletin of the Atomic Scientists, 1/13/2022:

In 2020, despite the COVID pandemic, scientists authored 6 million peer-reviewed publications, a 10 percent increase compared to 2019. At first glance this big number seems like a good thing, a positive indicator of science advancing and knowledge spreading. Among these millions of papers, however, are thousands of fabricated articles, many from academics who feel compelled by a publish-or-perish mentality to produce, even if it means cheating. […]

We have been able to spot fraudulent research thanks in large part to one key tell that an article has been artificially manipulated: The nonsensical “tortured phrases” that fraudsters use in place of standard terms to avoid anti-plagiarism software. Our computer system, which we named the Problematic Paper Screener, searches through published science and seeks out tortured phrases in order to find suspect work. While this method works, as AI technology improves, spotting these fakes will likely become harder, raising the risk that more fake science makes it into journals.

As of January 2022, we’ve found tortured phrases in 3,191 peer-reviewed articles published (and counting), including in reputable flagship publications.
