Genomic prediction of student flow through high school math curriculum

Compute polygenic EA scores for 3000 US high school students of European ancestry. Track individual progress from 9th to 12th grade, focusing on mathematics courses. The students are out-of-sample: not used in training of predictor. In fact, a big portion (over half?) of individuals used in predictor training are not even from the US -- they are from the UK/EU.

Results: predictor captures about as much variance as family background (SES = Social Economic Status). Students with lower polygenic scores are less likely to take advanced math (e.g., Geometry and beyond).

Typical education paths of individuals with, e.g., bottom few percentile polygenic score are radically different from those in the top percentiles, even after controlling for SES. For example, consider only rich kids or kids at superior schools and compare educational trajectory vs polygenic score. Looks like (bottom figure) odds ratio for taking Geometry in 9th grade is about 4-6x higher for top polygenic score kids.

Genetic Associations with Mathematics Tracking and Persistence in Secondary School

K. Paige Harden and Benjamin W. Domingue, et al.

...we address this question using student polygenic scores, which are DNA-based indicators of propensity to succeed in education8. We integrated genetic and official school transcript data from over 3,000 European-ancestry students from U.S. high schools. We used polygenic scores as a molecular tracer to understand how the flow of students through the high school math pipeline differs in socioeconomically advantaged versus disadvantaged schools. Students with higher education polygenic scores were tracked to more advanced math already at the beginning of high school and persisted in math for more years...

...including family-SES and school-SES as covariates attenuated the association between the education-PGS and mathematics tracking in the 9th-grade only by about 20% (attenuated from b = 0.583, SE = .034, to b = 0.461, SE = .036, p < 2 × 10-16, Supplementary Table S3). Note that the association with genetics was roughly comparable in magnitude to the association with familySES...

Interview with Genetic Engineering & Biotechnology News

Polygenic Risk Scores and Genomic Prediction: Q&A with Stephen Hsu

In this exclusive interview, Stephen Hsu (Michigan State University and co-founder of Genomic Prediction) discusses the application of polygenic risk scores (PRS) for complex traits in pre-implantation genetic screening. Interview conducted by Julianna LeMieux (GEN).

GEN: What motivated you to start Genomic Prediction?

STEVE HSU: It has a very long history. Laurent Tellier is the CEO and we’ve known each other since 2010. We’d been working on the background science of how to use machine learning to look at lots of genomes and then learn to predict phenotypes from that information.

We were betting on the continuing decline in cost for genotyping, and it paid off because now there are millions of genotypes available for analysis. We’d always thought that one of the best and earliest applications of this would be embryo selection because we can help families have a healthy child.

GEN: How did you first get interested in genomics in general, given your educational background in physics?

HSU: I was interested in genetics and evolution, molecular biology, since I was a kid. I grew up in the ’70s and ’80s and already at that time there was a lot of attention focused on the molecular biology revolution, recombinant DNA. We were always told physics is a very mature subject and biology is the subject of the future and it will just explode eventually with these new molecular techniques.

When I got to college and I took some classes in molecular biology, I realized that a lot of the deep questions—like how do you actually decipher a genome and figure out which pieces of the genetic code have direct consequences in phenotypes or complex traits?—would not be answerable with the technology of that time. So I put it aside and did theoretical physics, but got re-interested around the time I met Laurent. I became aware of the super exponential cost curve for genotyping, sequencing in particular. I realized, if this continues for another ten years or so, we’re going to be able to answer all these interesting questions I’ve been thinking about since I was a kid.

...

GEN: How do you generate a polygenic risk score for different diseases? Of the eight diseases listed on the Genomic Prediction website, are those diseases that your lab has basically generated that data for?

HSU: Many of them were produced by my research group, but the current best-performing breast cancer predictor actually comes from a large international consortium that works on breast cancer…

We use the same data that people would use for GWAS [genome-wide association studies]. For example, we might have 200,000 controls and 20 or 30,000 cases of people in their 50s and 60s who are old enough that they would have been diagnosed for diabetes (or something) if they had it. The algorithm knows which ones are the cases and which are the controls, and it also has about 1 million SNPs from each person, typically what you get from an Affymetrix or an Illumina array.

It is a learning algorithm that tries to tune its internal model so that it best predicts whether someone is actually a case or a control. There’s a bunch of fancy math involved in this—a high-dimensional optimization. You are basically finding the model that best predicts the data.

It is different from GWAS because GWAS is very simple—you look at a particular gene or SNP and you say is there statistical evidence that this particular SNP is associated with whether you have diabetes? You get a yes/no answer. If the P value is significant enough then you say we found a hit.

That problem mathematically is very different from the problem we solved. We are actually doing an optimization in a million-dimensional space to find simultaneously all the SNPs that should be activated in our predictor. This is all in the technical weeds but it is just different mathematics…

We think we can actually predict risk by doing this high-dimensional optimization. Initially, people just thought we were crazy. We wrote theoretical papers predicting how much data would you need to be able to accurately predict height or something like that. ... [ AND THOSE PREDICTIONS WERE CORRECT ... ]

James Salter: A Sport and a Pastime (documentary)

The documentary James Salter: A Sport and a Pastime is now available free to Amazon Prime subscribers.

This 54-minute documentary traces the writer James Salter's lifelong love affair with France, unforgettably expressed in his 1967 masterpiece, A Sport and a Pastime. The film captures the great purity of Salter's prose and the essence of his power to evoke the erotic. Salter's own reflections on his writing and life offer rich insights for reader and writer alike.

The excerpt below is from his 1993 interview for Paris Review's The Art of Fiction.

INTERVIEWER

When A Sport and a Pastime came out you were hailed as “celebrating the rites of erotic innovation” and yet also criticized for portraying such “vigorous ‘love’ scenes.” What did you think of all that?

SALTER

The eroticism is the heart and substance of the book. That seems obvious. I meant it to be, to use a word of Lorca’s, “lubricious” but pure, to describe things that were unspeakable in one sense, but at the same time, irresistible. Having traveled, I also was aware that voyages are, in a large sense, a search for, a journey toward love. A voyage without that is rather sterile. Perhaps this is a masculine view, but I think not entirely. The idea is of a life that combines sex and architecture—I suppose that’s what the book is, but that doesn’t explain it. It’s more or less a guide to what life might be, an ideal.

INTERVIEWER

People seem to have different opinions of what the book is about.

SALTER

I listen occasionally to people explaining the book to me. Every few years there’s an inquiry from a producer who would like to make a movie of it. I’ve turned the offers down because it seems to me ridiculous to try and film it. To my mind the book is obvious. I don’t see the ambiguity, but there again, you don’t know precisely what you are writing. Besides, how can you explain your own work? It’s vanity. To me it seems you can understand the book, if there’s been any doubt, by reading the final paragraph:

As for Anne-Marie, she lives in Troyes now, or did. She is married. I suppose there are children. They walk together on Sundays, the sunlight falling upon them. They visit friends, talk, go home in the evening, deep in the life we all agree is so greatly to be desired.

That paragraph, the final sentence, is written in irony, but perhaps not read that way. If you don’t see the irony, then the book is naturally going to have a different meaning for you.

INTERVIEWER

It has been said that Dean’s desire for Anne-Marie is also a desire for the “real” France. It’s a linked passion.

SALTER

France is beautiful, but his desire is definitely for the girl herself. Of course she is an embodiment. Even when you recognize what she is, she evokes things. But she would be desirable to him even if she didn’t.

INTERVIEWER

There’s a postmodern side to the book. The narrator indicates that he’s inventing Dean and Anne-Marie out of his own inadequacies.

SALTER

That’s just camouflage.

INTERVIEWER

What do you mean?

SALTER

This book would have been difficult to write in the first person—that is to say if it were Dean’s voice. It would be quite interesting written from Anne-Marie’s voice, but I wouldn’t know how to attempt that. On the other hand, if it were in the third person, the historic third, so to speak, it would be a little disturbing because of the explicitness, the sexual descriptions. The question was how to paint this, more or less. I don’t recall how it came to me, but the idea of having a third person describe it, somebody who is really not an important part of the book but merely serving as an intermediary between the book and the reader, was perhaps the thing that was going to make it possible; and consequently, I did that. I don’t know who this narrator is. You could say it’s me; well, possibly. But truly, there is no such person. He’s a device. He’s like the figure in black that moves the furniture in a play, so to speak, essential, but not part of the action.

...

INTERVIEWER

What do you think is the ultimate impulse to write?

SALTER

To write? Because all this is going to vanish. The only thing left will be the prose and poems, the books, what is written down. Man was very fortunate to have invented the book. Without it the past would completely vanish, and we would be left with nothing, we would be naked on earth.

MSU Research Update (video)

Remarks at a recent Michigan State University leadership meeting. MSU is currently #1 in the US in annual Department of Energy (DOE) and DOE + NSF (National Science Foundation) funding. There are ~30 institutions in the US with larger annual research expenditures than MSU, however in all but a few cases (e.g., MIT and UC Berkeley) this is due to a large medical research complex and significant NIH (National Institutes of Health) funding. I discuss MSU's strategy in this direction: a new biomedical research complex and new $450M McLaren hospital on our campus.

#RussiaHoax is the new WMD

No, there was never any Russian Collusion. But there was illegal spying on the political opposition by the Obama intelligence services. With the Mueller investigation now out of the way, I hope to see important, previously hidden, information declassified in the near future:

1. Multiple FISA applications to spy on anyone within "two hops" of Carter Page (i.e., the entire Trump campaign and transition team)

2. Originating Electronic Communication (EC) from CIA Director John Brennan to FBI Director James Comey. The two-page EC gives Brennan's justification for operation “Crossfire Hurricane” to investigate the Trump campaign (July 31, 2016).

3. Sworn testimony by Strzok, Ohr, Page, McCabe, etc. etc.

See, e.g., Spygate in 20 Minutes and Deep State Update.

If you took the #RussiaHoax seriously, and have any pretensions to rationality, then you must update your priors concerning the reliability of the media, and of our security and intelligence services.

Below, an excerpt from Matt Taibbi's forthcoming book Hate Inc.

It's official: Russiagate is this generation's WMD

The Iraq war faceplant damaged the reputation of the press. Russiagate just destroyed it

Nobody wants to hear this, but news that Special Prosecutor Robert Mueller is headed home without issuing new charges is a death-blow for the reputation of the American news media.

As has long been rumored, the former FBI chief’s independent probe will result in multiple indictments and convictions, but no “presidency-wrecking” conspiracy charges, or anything that would meet the layman’s definition of “collusion” with Russia.

With the caveat that even this news might somehow turn out to be botched, the key detail in the many stories about the end of the Mueller investigation was best expressed by the New York Times:

A senior Justice Department official said that Mr. Mueller would not recommend new indictments.

The Times tried to soften the emotional blow for the millions of Americans trained in these years to place hopes for the overturn of the Trump presidency in Mueller. Nobody even pretended it was supposed to be a fact-finding mission, instead of an act of faith.

The Special Prosecutor literally became a religious figure during the last few years, with votive candles sold in his image and Saturday Night Live cast members singing “All I Want for Christmas is You” to him featuring the rhymey line: “Mueller please come through, because the only option is a coup.”

The Times story today tried to preserve Santa Mueller’s reputation, noting Trump’s Attorney General William Barr’s reaction was an “endorsement” of the fineness of Mueller’s work:

In an apparent endorsement of an investigation that Mr. Trump has relentlessly attacked as a “witch hunt,” Mr. Barr said Justice Department officials never had to intervene to keep Mr. Mueller from taking an inappropriate or unwarranted step.

Mueller, in other words, never stepped out of the bounds of his job description. But could the same be said for the news media?

For those anxious to keep the dream alive, the Times published its usual graphic of Trump-Russia “contacts,” inviting readers to keep making connections. But in a separate piece by Peter Baker, the paper noted the Mueller news had dire consequences for the press:

It will be a reckoning for President Trump, to be sure, but also for Robert S. Mueller III, the special counsel, for Congress, for Democrats, for Republicans, for the news media and, yes, for the system as a whole…

This is a damning page one admission by the Times. Despite the connect-the-dots graphic in its other story, and despite the astonishing, emotion-laden editorial the paper also ran suggesting “We don’t need to read the Mueller report” because we know Trump is guilty, Baker at least began the work of preparing Times readers for a hard question: “Have journalists connected too many dots that do not really add up?”

The paper was signaling it understood there would now be questions about whether or not news outlets like itself made galactic errors by betting heavily on a new, politicized approach, trying to be true to “history’s judgment” on top of the hard-enough job of just being true. Worse, in a brutal irony everyone should have seen coming, the press has now handed Trump the mother of campaign issues heading into 2020.

Here is the Wall Street Journal:

WSJ: Mueller Is Done. Now Probe the Real Scandal

Attorney General William Barr has reported to Congress that special counsel Robert Mueller has cleared President Trump and his campaign team of claims of conspiring with Russia during the 2016 election. This is more than an exoneration. It’s a searing indictment of the Federal Bureau of Investigation, as well as a reminder of the need to know the story behind the bureau’s corrosive investigation.

Mr. Mueller’s report likely doesn’t put it that way, but it’s the logical conclusion of his no-collusion finding. The FBI unleashed its powers on a candidate for the office of the U.S. presidency, an astonishing first. It did so on the incredible grounds that the campaign had conspired to aid a foreign government. And it used the most aggressive tools in its arsenal—surveillance of U.S. citizens, secret subpoenas of phone records and documents, even human informants.

... None of this should ever have happened absent highly compelling evidence—from the start—of wrongdoing. Yet from what we know, the FBI operated on the basis of an overheard conversation of third-tier campaign aide George Papadopoulos, as well as a wild “dossier” financed by the rival presidential campaign. Mr. Mueller’s no-collusion finding amounts to a judgment that there never was any evidence. The Papadopoulos claim was thin, the dossier a fabrication.

Which is all the more reason Americans now deserve a full accounting of the missteps of former FBI Director James Comey and his team—in part so that this never happens again. That includes the following: What “evidence” did the FBI have in totality? What efforts did the bureau take to verify it? Did it corroborate anything before launching its probe? What role did political players play? How aware was the FBI that it was being gulled into a dirty-trick operation, and if so, how did it justify proceeding? How intrusive were the FBI methods? And who was harmed?

Annals of Psychometry: 35 years of talent selection

David Lubinski kindly shared the recent paper linked below. He and I will both be at ISIR 2019, the annual meeting of the International Society for Intelligence Research.

Psychological Constellations Assessed at Age 13 Predict Distinct Forms of Eminence 35 Years Later (Psychological Science 2019, Vol. 30(3) 444–454).

The paper studies two populations:

1. 13 year olds identified through talented and gifted programs, all of whom scored in the top 1% in at least one of Mathematical or Verbal ability (based on SAT score; some scored at the 1 in 10k level). They were also assessed using a preference inventory (SOV = Study of Values). About 10% of this cohort of 677 were identified 35 years later as having achieved "eminence" in their careers -- e.g., full professor at R1 university, senior executive status, ...

2. Exceptional STEM graduate students at top 15 PhD programs, evaluated using GRE and SOV. If I'm not mistaken many or all of these students were NSF Graduate Fellows. About 20% of this population of 605 had achieved STEM eminence 25 years later.

I would estimate that only about one in a thousand individuals drawn randomly from the general population attains eminence as defined in the paper. Thus, the talent selection used to form cohorts 1&2 (e.g., SAT administered at age 13) produced success rates as much as 100 times higher than in the base population.

Psychological Constellations Assessed at Age 13 Predict Distinct Forms of Eminence 35 Years Later

Abstract
This investigation examined whether math/scientific and verbal/humanistic ability and preference constellations, developed on intellectually talented 13-year-olds to predict their educational outcomes at age 23, continue to maintain their longitudinal potency by distinguishing distinct forms of eminence 35 years later. Eminent individuals were defined as those who, by age 50, had accomplished something rare: creative and highly impactful careers (e.g., full professors at research-intensive universities, Fortune 500 executives, distinguished judges and lawyers, leaders in biomedicine, award-winning journalists and writers). Study 1 consisted of 677 intellectually precocious youths, assessed at age 13, whose leadership and creative accomplishments were assessed 35 years later. Study 2 constituted a constructive replication—an analysis of 605 top science, technology, engineering, and math (STEM) graduate students, assessed on the same predictor constructs early in graduate school and assessed again 25 years later. In both samples, the same ability and preference parameter values, which defined math/scientific versus verbal/humanistic constellations, discriminated participants who ultimately achieved distinct forms of eminence from their peers pursuing other life endeavors.

Note that even within both cohorts SAT / GRE were useful in predicting achievement outcomes. Click figures below for larger versions.

Othram: the future of DNA forensics

I've blogged frequently about the impact of the genomic revolution on embryo selection in IVF and precision health (complex disease risk prediction).

DNA forensics -- the use of DNA for identification of criminals, victims, military remains, etc. -- will also be transformed by inexpensive genotyping and powerful informatics.

The existing FBI standard (CODIS) for DNA identification uses only 20 markers (STRs -- previously only 13 loci were used!). By contrast, genome wide sequencing can reliably call millions of genetic variants. For the first time, the cost curves for these two methods have crossed: modern sequencing costs no more than extracting CODIS markers using the now ~30 year old technology.

What can you do with millions of genetic markers?

1. Determine relatedness of two individuals with high precision. This allows detectives to immediately identify a relative (ranging from distant cousin to sibling or parent) of the source of the DNA sample, simply by scanning through large DNA databases. In many cases this narrows the pool of suspects to ~100 or fewer individuals. With only 20 CODIS markers this is not possible. Some notorious cold cases have already been solved using this method, with more examples every few weeks.

2. Phenotype and Ancestry reports: in addition to ethnicity, we can now predict cosmetic traits such as hair color, eye color, skin tone (i.e., light to dark), baldness, height, BMI, and bodyfat percentage. (The last two are the least accurate, although outlier ares still identifiable.) Again, not remotely possible using CODIS markers.

I'm a co-founder of Othram, a startup providing 1&2 above to law enforcement, the military, and other customers.

Recently I visited Othram's brand new 4000 square foot lab which will be entirely dedicated to forensic applications of advanced sequencing and genomic prediction. The lab has specialized air handling and sample processing infrastructure, and will soon be home to an Illumina NovaSeq.

On the legal status of large DNA databases, such as those of 23andMe and Ancestry: these firms have genotyped 5M and 10M individuals, respectively, with both numbers set to double in the next year. These datasets are large enough to, e.g., immediately return a first- or second-cousin match for most searches on DNA from someone of primarily European heritage. With such resources the majority of crimes with DNA evidence become easy to solve. The Genomic Panopticon is nearly a reality.

Both 23andMe and Ancestry have, on grounds of customer privacy, resisted law enforcement requests to search for matches to forensic DNA. However, one of their smaller competitors, FamilyTreeDNA, revealed that it is routinely collaborating with FBI. I do not believe that 23andMe or Ancestry can resist a court order if vigorously pursued. The situation is similar to that of ISPs and web email providers in the early days of the internet. They also resisted cooperation with law enforcement on privacy grounds, but in the end had to capitulate. All such firms today have compliance departments that process law enforcement queries on a routine basis. I would be very surprised if 23andMe and Ancestry don't end up with a similar accommodation, despite their current posture.

Kip Thorne on Caltech and Black Holes

See LIGO Detects Gravity Waves and The Christy Gadget.

Techno-pessimists should note that detecting gravity waves is much, much harder than landing on the moon. LIGO measured a displacement 1/1000 of a neutron radius, in a noisy terrestrial background, accounting even for quantum noise.

https://www.ligo.caltech.edu/: 9/14/15 detection of BH-BH (~ 30 solar masses) merger at distance 1.3 Gy. The energy in the gravitational wave signal was ~3 solar masses!

Here is the paper http://journals.aps.org/prl/abstract/10.1103/PhysRevLett.116.061102

When I was an undergraduate, I toured the early LIGO prototype, which was using little car shaped rubber erasers as shock absorbers. Technology has improved since then, and the real device is much bigger.

As Kip makes clear in his talk, the detection of gravity waves was a ~50 year project involving large numbers of very smart physicists and engineers, with the sustained support of some of the most impressive scientific institutions in the world (Caltech, MIT, NSF, Moscow State University). Entirely new technologies and areas of theoretical and experimental physics had to be developed to bring this dream to fruition.

I learned general relativity from Kip when I was at Caltech. The photo below was taken in Eugene, Oregon. Physics as a Strange Attractor.

Mootoo Kimura: "do something in genetics ... like theoretical physics"

I have written previously about James Crow and R.A. Fisher. Now to Mootoo Kimura.

Wikipedia: Motoo Kimura (木村 資生 Kimura Motō) (November 13, 1924 – November 13, 1994) was a Japanese biologist best known for introducing the neutral theory of molecular evolution in 1968.[2][3] He became one of the most influential theoretical population geneticists. He is remembered in genetics for his innovative use of diffusion equations to calculate the probability of fixation of beneficial, deleterious, or neutral alleles.[4] Combining theoretical population genetics with molecular evolution data, he also developed the neutral theory of molecular evolution in which genetic drift is the main force changing allele frequencies.[5] James F. Crow, himself a renowned population geneticist, considered Kimura to be one of the two greatest evolutionary geneticists, along with Gustave Malécot, after the great trio of the modern synthesis, Ronald Fisher, J. B. S. Haldane and Sewall Wright.[6]

What is the fate of the neutral theory? I suppose the fundamental question is what fraction of molecular changes (mutations) have significant phenotypic effects (i.e., effects on fitness). If the fraction is very small then one could, at the molecular level, adopt the neutral theory as a first approximation. (At the level of phenotypes, I can't see drift dominating unless the effective population size is very small.) Still unsettled?

Wikipedia: ... According to Kimura, the theory applies only for evolution at the molecular level, and phenotypic evolution is controlled by natural selection, as postulated by Charles Darwin. The proposal of the neutral theory was followed by an extensive "neutralist-selectionist" controversy over the interpretation of patterns of molecular divergence and polymorphism, peaking in the 1970s and 1980s. Since then, much evidence has been found for selection at molecular level.

The article Kimura & Crow: Infinite alleles, appeared in Genes to Genomes, the blog of the Genetics Society of America. (See also here ;-)

... Kimura was originally trained as a plant cytologist; he had been fascinated by plants since boyhood, and cytogenetics had been the hot field in Japan at the time. But his interest in chromosomes waned as he began yearning to “do something in genetics like what the theoretical physicists were doing in physics.” This ambition was buoyed by Kimura’s regular, hunger-fueled excursions to the house of his cousin-in-law Matsuhei Tamura, a mathematical physicist. Kimura visited almost every Sunday, partly because he was intensely interested in the quantum physicist’s stories, and partly because he needed to fill his belly during the post-war food shortages.

Kimura joined the lab of Japan’s most famous cytogeneticist, Hitoshi Kihara, who recognized the quiet young man’s talent for theory and left him mostly to his own devices. So, while his friends picked apart the chromosomes of wheat and watermelon, Kimura indulged in the more abstract pleasures of population genetics. He would travel the full-day’s train journey to Tokyo to copy out by hand the papers of Sewall Wright, one of the founders of the field. Determined to understand Wright’s papers, Kimura haunted the math department, attending classes, asking questions, learning from books, until he gradually gained the sophistication to follow Wright’s arguments, and eventually, critique and extend them.

But this new intellectual world was isolating. Kimura’s lab mates took a dim view of his absorption in mathematics and the situation only worsened when he took a job at the newly founded National Institute of Genetics. The facility was housed in the makeshift and uncomfortable office of a wartime aircraft factory. There was no library, no access to foreign journals, and no colleague who could understand his work. The only geneticist there who saw its value was zoologist Taku Komai, who had studied in the fly lab of genetics superstar T. H. Morgan in the United States. Komai recommended Kimura extend his training overseas and introduced him to an American scientist working for the Atomic Bomb Casualty Commission. Before long Kimura had a scholarship, a Fulbright travel award, and a ticket to Seattle.

Once they met, Crow immediately took Kimura under his wing. He invited Kimura over for dinner to meet his idol Sewall Wright. Crow probed Kimura about the paper he had just written on the Pacific voyage and was impressed that it neatly reduced a formidably complex equation down to a simple relationship used by physicists to describe heat conduction. He encouraged Kimura to submit the paper to GENETICS, where Crow was an editor (the paper was later effusively and uncharacteristically praised by its reviewer, Wright).

Always an Eccentric? A Brief Biography of Mootoo Kimura:

To Predict the Future it is useful to understand the Past

Dominic Cummings on genomics, healthcare, and innovation in the UK:

Britain could contribute huge value to the world by leveraging existing assets, including scientific talent and how the NHS is structured, to push the frontiers of a rapidly evolving scientific field — genomic prediction — that is revolutionising healthcare in ways that give Britain some natural advantages over Europe and America. We should plan for free universal ‘SNP’ genetic sequencing as part of a shift to genuinely preventive medicine — a shift that will lessen suffering, save money, help British advanced technology companies in genomics and data science/AI, make Britain more attractive for scientists and global investment, and extend human knowledge in a crucial field to the benefit of the whole world.

Those that are interested in the history of science, or in understanding its future, would do well to look at what was being written 10 or so years ago about genomics of complex traits. Whose predictions came true? Whose were dead wrong?

Dominic Cummings: ... Hsu predicted that very large samples of DNA would allow scientists over the next few years to start identifying the actual genes responsible for complex traits, such as diseases and intelligence, and make meaningful predictions about the fate of individuals. Hsu gave estimates of the sample sizes that would be needed. His 2011 talk contains some of these predictions and also provides a physicist’s explanation of ‘what is IQ measuring’. As he said at Google in 2011, the technology is ‘right on the cusp of being able to answer fundamental questions’ and ‘if in ten years we all meet again in this room there’s a very good chance that some of the key questions we’ll know the answers to’. His 2014 paper explains the science in detail. If you spend a little time looking at this, you will know more than 99% of high status economists gabbling on TV about ‘social mobility’ saying things like ‘doing well on IQ tests just proves you can do IQ tests’.

In 2013, the world of Westminster thought this all sounded like science fiction and many MP said I sounded like ‘a mad scientist’. Hsu’s predictions have come true and just five years later this is no longer ‘science fiction’. (Also NB. Hsu’s blog was one of the very few places where you would have seen discussion of CDOs and the 2008 financial crash long BEFORE it happened. I have followed his blog since ~2004 and this from 2005, two years before the crash started, was the first time I read about things like ‘synthetic CDOs’: ‘we have yet another ill-understood casino running, with trillions of dollars in play’. The quant-physics network had much better insight into the dynamics behind the 2008 Crash than high status mainstream economists like Larry Summers responsible for regulation.)

His group and others have applied machine learning to very large genetic samples and built predictors of complex traits. Complex traits like general intelligence and most diseases are ‘polygenic’ — they depend on many genes each of which contributes a little (unlike diseases caused by a single gene).

‘There are now ~20 disease conditions for which we can identify, e.g, the top 1% outliers with 5-10x normal risk for the disease. The papers reporting these results have almost all appeared within the last year or so.’

(One might ask what fraction of PhD economists knew in 2008 what a CDO was or how they were constructed or priced... I was there, and the answer is: very, very few.)

As the deep learning pioneer Jurgen Schmidhuber has emphasized,

... machine learning is itself based on accurate credit assignment. Good learning algorithms assign higher weights to features or signals that correctly predict outcomes, and lower weights to those that are not predictive. His analogy between science itself and machine learning is often lost on critics.

Therefore, to decide how to weight current claims about the future (such as: accurate genomic prediction of many disease risks and complex traits, even including cognitive ability, are right around the corner), one should carefully study the track record of those offering predictions.

Russia, China, and the New Cold War

Overly aggressive US foreign and economic policies toward Russia and China are pushing the two into a tighter relationship. US rapprochement with China, exploiting Sino-Soviet tensions, was an important achievement of Nixon and Kissinger in the previous Cold War. Today a solidified Russia-China bloc is an extremely negative development for US interests.

There are important synergies between the two countries. Russia still leads in key military technologies, and can supply China with badly needed natural resources.  China has a more vibrant economy and is starting to surge into global leadership across a range of technologies and in manufacturing.

The main source of potential conflict between the two is the sparsely populated, but resource rich, Russian Far East. I doubt territorial ambitions there are a top priority for China, especially if an amicable trading relationship can be established for oil, gas, and other resources. Chinese economic influence in the region is growing, threatening to overwhelm the Russians. But the trajectory is manageable if both sides agree to cooperate.

The article excerpted below is by Bruno Maçães, a former Europe minister for Portugal, and author of The Dawn of Eurasia (Penguin 2018).

Politico (EU): ... In the halls of the Kremlin these days, it’s all about China — and whether or not Moscow can convince Beijing to form an alliance against the West.

Russia’s obsession with a potential alliance with China was already obvious at the Valdai Discussion Club, an annual gathering of Russia’s biggest foreign policy minds, in 2017.

At their next meeting, late last year, the idea seemed to move from the speculative to something Russia wants to realize. And soon.

... Every Russian speech — from obscure academics to Foreign Minister Sergei Lavrov and Russian President Vladimir Putin himself — played that note and no other. There was even a new sense of desperation in the air.

As Sergey Karaganov, a former adviser to Putin, explained to me at breakfast, now everything must be about China.

... There was no doubt at Valdai that China knows how to do economic growth, and that Russia does not. Russia’s elite — always so ready to resist any sign of Western hegemony — have no problem admitting China’s economic superiority. Their acceptance reminded me of the way Britain gave way to the United States as the world’s dominant economic power.

... In the past, the possibility of an alliance between the two countries had been hampered by China’s reluctance to jeopardize its relations with the U.S. But now that it has already become a target, perhaps it will grow bolder. Every speaker at Valdai tried to push China in that direction.

When Putin finished a fireside chat with policymakers — a set-piece of the conference, where he fields softball questions from the audience — he made a gesture to leave the room, but then quickly rushed back to grab Yang Jiechi, a former Chinese foreign minister and arguably the main architect of the country’s foreign policy. He insisted on walking out with Yang by his side, to the obvious delight of his Chinese guest.

... I met Karaganov again at a meeting with Chinese officials and think tankers in Beijing a few weeks ago. There, a number of Chinese participants said they doubted Russia’s assertions that the world is in the midst of a new Cold War.

Karaganov dedicated himself to convincing them otherwise, arguing with increasing passion that China is deluding itself if it thinks issues between Beijing and Washington can be conveniently resolved to the benefit of both sides.

If Beijing places its bets on peace and cooperation, the great Chinese adventure will come to an end, and China will have to live in the shadow of the U.S. for another generation — perhaps forever, Karaganov said. Chinese authorities, he argued, have no more than five years to make a decision.

The meeting was held under the Chatham House rule, so unfortunately, I cannot report on what the response from the Chinese side was; only Karaganov allowed me to relay his words.

... from my own separate conversations, Chinese officials appear to agree the clock is ticking. They’re just not yet convinced they should choose war — even a Cold War.

Ice Cream Kron

First UFC victory by a Gracie since 1994! Congratulations to Kron, son of Rickson Gracie. His nickname, Ice Cream Kron, means Cool Under Pressure. Ironically, you can tell that he's a sensitive guy and that fighting takes a huge toll on him.

He won in old school fashion. The progression was classic -- something I taught to Yale BJJ club students in the mid-1990s. Caceres throws a right, Kron ducks under to get the clinch, hiding his head under Cacere's arm. Kron takes the back, entwines his leg and uses his bodyweight to take Caceres to the mat. Kron moves smoothly into a rear naked choke, hiding his hands from Caceres. Almost no energy expended by Kron. Alex Caceres, an athletic UFC veteran, defeated in 90 seconds with a minimum of violence.

Jiujitsu, the gentle art.




Some background on Rickson and Kron, from Eddie Bravo and Joe Rogan. Kron's submission grappling fights against Garry Tonon and Marcelo Garcia are unbelievable.

Precision Genomic Medicine and the UK

I just returned from the UK, where I attended a Ditchley Foundation Conference on machine learning and genetic engineering. The attendees included scientists, government officials, venture capitalists, ethicists, and medical professionals.

The UK could become the world leader in genomic research by combining population-level genotyping with NHS health records. The application of AI to datasets of this kind has already led to the creation of genomic predictors that can identify individuals at high risk for common disease conditions such as breast cancer, heart disease, diabetes, hypothyroidism, etc. Such breakthroughs provide insight into the genetics of disease, and allow more efficient allocation of resources for prevention and early detection to the individuals who would most benefit. This saves both lives and money.

The US private health insurance system produces the wrong incentives for this kind of innovation: payers are reluctant to fund prevention or early treatment because it is unclear who will capture the ROI. Consider a cost-effective intervention that, e.g., prevents a patient from developing diabetes. This produces an obvious health benefit, but if the patient later changes insurer the financial benefits are lost to the one that paid for the intervention. Not a problem, though, in a single-payer system.

The NHS has the right incentives, the necessary scale, and access to a deep pool of scientific talent. The UK can lead the world into a new era of precision genomic medicine.

NHS has already announced an out-of-pocket genotyping service which allows individuals to pay for their own genotyping and to contribute their health + DNA data to scientific research. In recent years NHS has built an impressive infrastructure for whole genome sequencing (cost ~$1k per individual) that is used to treat cancer and diagnose rare genetic diseases. The NHS subsidiary Genomics England recently announced they had reached the milestone of 100k whole genomes.

For common conditions such as heart disease, diabetes, breast cancer, etc., most of the recent advances in risk prediction have come from even larger datasets (many hundreds of thousands of individuals) with genotypes from inexpensive arrays (~$50; like those used by 23andMe) that sample the genome at the roughly million or so most informative locations. By contrast, a whole genome sequence measures all 3 billion base pairs. This provides more raw data per individual, but we do not currently know how to use most of that information.

At the meeting, I emphasized the following:

1. NHS should offer both inexpensive (~$50) genotyping (sufficient for risk prediction of common diseases) along with the more expensive $1k whole genome sequencing. This will alleviate some of the negative reaction concerning a "two-tier" NHS, as many more people can afford the former.

2. An in-depth analysis of cost-benefit for population wide inexpensive genotyping would likely show a large net cost savings: the risk predictors are good enough already to guide early interventions that save lives and money. Recognition of this net benefit would allow NHS to replace the $50 out-of-pocket cost with free standard of care.

More on genomic precision medicine.

Brexit, the movie: Benedict Cumberbatch as Dominic Cummings

The Brexit movie, starring Benedict Cumberbatch as Dominic Cummings, is really good.

I was able to watch it online for free: Channel 4 in the UK. (Perhaps you can do that as well if you don't get HBO.)

I had to see it this afternoon before heading over to Dom's for dinner tonight :-)

See Dom's blog On the referendum #20: the campaign, physics and data science

We created new software. This was a gamble but the whole campaign was a huge gamble and we had to take many calculated risks. One of our central ideas was that the campaign had to do things in the field of data that have never been done before. This included a) integrating data from social media, online advertising, websites, apps, canvassing, direct mail, polls, online fundraising, activist feedback, and some new things we tried such as a new way to do polling (about which I will write another time) and b) having experts in physics and machine learning do proper data science in the way only they can – i.e. far beyond the normal skills applied in political campaigns. We were the first campaign in the UK to put almost all our money into digital communication then have it partly controlled by people whose normal work was subjects like quantum information ...

If you want to make big improvements in communication, my advice is – hire physicists, not communications people from normal companies and never believe what advertising companies tell you about ‘data’ unless you can independently verify it. Physics, mathematics, and computer science are domains in which there are real experts, unlike macro-economic forecasting which satisfies neither of the necessary conditions – 1) enough structure in the information to enable good predictions, 2) conditions for good fast feedback and learning. Physicists and mathematicians regularly invade other fields but other fields do not invade theirs so we can see which fields are hardest for very talented people. It is no surprise that they can successfully invade politics and devise things that rout those who wrongly think they know what they are doing. Vote Leave paid very close attention to real experts. (The theoretical physicist Steve Hsu has a great blog HERE which often has stuff on this theme, e.g. HERE.)

More important than technology is the mindset – the hard discipline of obeying Richard Feynman’s advice: ‘The most important thing is not to fool yourself and you are the easiest person to fool.’ They were a hard floor on ‘fooling yourself’ and I empowered them to challenge everybody including me. They saved me from many bad decisions even though they had zero experience in politics and they forced me to change how I made important decisions like what got what money. We either operated scientifically or knew we were not, which is itself very useful knowledge.
