The US is trying to kick-start a “nuclear energy renaissance”


Push to revive nuclear energy relies on deregulation; experts say strategy is misplaced.

In May, President Donald Trump signed four executive orders to facilitate the construction of nuclear reactors and the development of nuclear energy technology; the orders aim to cut red tape, ease approval processes, and reshape the role of the main regulatory agency, the Nuclear Regulatory Commission, or NRC. These moves, the administration said, were part of an effort to achieve American independence from foreign power providers by way of a “nuclear energy renaissance.”

Self-reliance isn’t the only factor motivating nuclear power proponents outside of the administration: Following a decades-long trend away from nuclear energy, in part due to safety concerns and high costs, the technology has emerged as a potential option to try to mitigate climate change. Through nuclear fission, in which atoms are split to release energy, reactors don’t emit any greenhouse gases.

The Trump administration wants to quadruple the nuclear sector’s domestic energy production, with the goal of producing 400 gigawatts by 2050. To help achieve that goal, scientific institutions like the Idaho National Laboratory, a leading research institute in nuclear energy, are pushing forward innovations such as more efficient types of fuel. Companies are also investing millions of dollars to develop their own nuclear reactor designs, a move from industry that was previously unheard of in the nuclear sector. For example, Westinghouse, a Pennsylvania-based nuclear power company, plans to build 10 new large reactors to help achieve the 2050 goal.

However, the road to renaissance is filled with familiar obstacles. Nuclear energy infrastructure is “too expensive to build, and it takes too long to build,” said Allison Macfarlane, a science and technology policy expert at the University of British Columbia who used to chair the NRC from 2012 to 2014.

And experts are divided on whether new nuclear technologies, such as small versions of reactors, are ready for primetime. The nuclear energy field is now “in a hype bubble that is driving unrealistic expectations,” said Edwin Lyman, the director of nuclear power safety at the Union of Concerned Scientists, a nonprofit science advocacy organization that has long acted as a nuclear safety watchdog.

Meanwhile, the Trump administration is trying to advance nuclear energy by weakening the NRC, Lyman said. “The message is that it’s regulation that has been the obstacle to deploying nuclear power, and if we just get rid of all this red tape, then the industry is going to thrive,” he added. “I think that’s really misplaced.”

Although streamlining the approval process might accelerate development, the true problem lies in the high costs of nuclear, which would need to be significantly cheaper to compete with other sources of energy such as natural gas, said Koroush Shirvan, a nuclear science researcher at the Massachusetts Institute of Technology. “Even the license-ready reactors are still not economical,” he said. If the newer reactor technologies do pan out, without government support and subsidies, Shirvan said, it is difficult to imagine them “coming online before 2035.”

It’s déjá vu all over again

Rumblings of a nuclear renaissance give experts a sense of déjà vu. The first resurgence in interest was around 2005, when many thought that nuclear energy could mitigate climate change and be an energy alternative to dwindling supply and rising prices of fossil fuels. But that enthusiasm slowed mainly after the Fukushima accident in 2011, in which a tsunami-triggered power outage—along with multiple safety failures—led to a nuclear meltdown at a facility in Japan. “So, the first nuclear renaissance fizzled out,” said Lyman.

Globally, the proportion of electricity provided by nuclear energy has been dwindling. Although there has been an increase in generation, nuclear energy has contributed less to the share of global electricity demand, dropping to 9 percent in 2024 from a peak of about 17 percent in 2001. In the US, 94 reactors generate about a fifth of the nation’s electricity, a proportion that has held steady since 1990s. But only two of those reactors have come online in the last nearly 30 years.

This renewed push is “a second bite at the apple, and we’ll have to see but it does seem to have a lot more of a headwind now,” said Lyman.

Much of that movement comes from the private sector, said Todd Allen, a nuclear engineer at the University of Michigan. In the last couple of decades, dozens of nuclear energy companies have emerged, including TerraPower, co-founded by Bill Gates. “It feels more like normal capitalism than we ever had in nuclear,” Allen said. Those companies are working on developing the large reactors that have been the backbone of nuclear energy for decades, as well as newer technologies that can bolster the field.

Proponents say small modular reactors, or SMRs, and microreactors, which generate less than 300 megawatts and 20 megawatts, respectively, could offer safer, cheaper, and more flexible energy compared to their more traditional counterparts. (Large reactors have, on average, 900 megawatts of capacity.) One 2022 study found that modularization can reduce construction time by up to 60 percent.

These designs have taken the spotlight: In 2024, a report estimated that the SMR market would reach $295 billion by 2043. In June, Energy Secretary Chris Wright told Congress that DOE will have at least three SMRs running by July of next year. And in July of this year, the Nuclear Energy Agency launched a dashboard to track SMR technologies around the world, which identified 74 SMR designs at different stages around the world. The first commercial SMR in North America is currently being constructed in Canada, with plans to be operational by 2030.

But whether SMRs and microreactors are actually safer and more cost-effective remains to be determined. A 2022 study found that SMRs would likely produce more leakage and nuclear waste than conventional reactors. Studying them, though, is difficult since so few are currently operational.

In part, that may be because of cost. Multiple analyses have concluded that, because of rising construction and operating costs, SMRs might not be financially viable enough to compete for the world’s energy markets, including in developing countries that lack affordable access to electricity.

And recent ventures have hit road bumps: For example, NuScale, the only SMR developer with a design approved by the NRC, had to shut down its operations in November 2023 due to increasingly high costs (though another uprated SMR design was approved earlier this year).

“Nothing is really commercialized yet,” said Macfarlane. Most of the tech companies haven’t figured out expenses, supply chains, the kind of waste they are going to produce or security at their reactors, she added.

Fuel supply is also a barrier since most plants use uranium enriched at low rates, but SMRs and microreactors use uranium enriched at higher levels, which is typically sourced from Russia and not commercially available in the US. So scientists at the Idaho National Laboratory are working to recover enriched uranium from existing reactors and developed new, more cost-effective fuels, said Jess Gehin, the associate laboratory director for the Nuclear Science & Technology Directorate at the INL. They are also using artificial intelligence and modeling simulation tools and capabilities to optimize nuclear energy systems, he added: “We got to reach 400 gigawatts, we need to accelerate all of this.”

Companies are determined to face and surpass these barriers. Some have begun pouring concrete, such as one nuclear company called Kairos Power that began building a demo of their SMR design in Tennessee; the plant is projected to be fully operational by 2027. “I would make the case that we’re moving faster than many in the field, if not the fastest,” Mike Laufer, the company’s CEO and co-founder, told Reuters last year.

Some experts think achieving nuclear expansion can be done—and revel in the progress so far: “I would have never thought we’d be in this position where we’re working so hard to expand nuclear, because for most of my career, it wasn’t that way,” said Gehin. “And I would say each month that goes by exceeds my expectations on the next bigger things that are coming.”

Doing more with less?

Although the Trump administration aims to accelerate nuclear energy through executive orders, in practice, it has not allocated new funding yet, said Matt Bowen, an expert on nuclear energy, waste, and nonproliferation at Columbia University’s Center on Global Energy Policy. In fact, the initial White House budget proposed cutting $4.7 billion from the Department of Energy, including $408 million from the Office of Nuclear Energy allocated for nuclear research in the 2026 fiscal year.

“The administration was proposing cuts to Office of Nuclear Energy and DOE more broadly, and DOGE is pushing staff out,” said Bowen. “How do you do more with less? Less staff, less money.”

The Trump administration places the blame for the nuclear sector’s stagnation on the NRC, which oversees licensing and recertification processes that cost the industry millions of dollars each year in compliance. In his executive orders, Trump called for a major reorganization of the NRC. Some of the proposed changes, like streamlining the approval process (which can take years for new plants), may be welcomed because “for a long time, they were very, very, very slow,” said Charles Forsberg, a nuclear chemical engineer at MIT. But there are worries that the executive orders could do more than cut red tape.

“Every word in those orders is of concern, because the thrust of those orders is to essentially strip the Nuclear Regulatory Commission of its independence from the executive branch, essentially nullifying the original purpose,” said Lyman.

Some experts fear that with these new constraints, NRC staff will have less time and fewer resources to do their jobs, which could impact power plant safety in the future. Bowen said: “This notion that the problem for nuclear energy is regulation, and so all we need to do is deregulate, is both wrong and also really problematic.”

The next few decades will tell whether nuclear, especially SMRs, can overcome economic and technical challenges to safely contribute to decarbonization efforts. Some, like Gehin, are optimistic. “I think we’re going to accelerate,” he said. “We certainly can achieve a dramatic deployment if we put our mindset to it.”

But making nuclear financially competitive will take serious commitment from the government and the dozens of companies, with many still skeptical, Shirvan said. “I am quite, I would say, on the pessimistic scale when it comes to the future of nuclear energy in the US.”

NASA found intriguing rocks on Mars, so where does that leave Mars Sample Return?

NASA’s interim administrator, Sean Duffy, was fired up on Wednesday when he joined a teleconference to talk about new scientific findings that concerned the potential for life to have once existed on Mars.

“This is exciting news,” said Duffy about an arrow-shaped rock on Mars found by NASA’s Perseverance rover. The rock contained chemical signatures and structures that could have been formed by ancient microbial life. The findings were intriguing, but not conclusive. Further study of the rocks in an advanced lab on Earth might prove more definitive.

Duffy was ready, he said, to discuss the scientific results along with NASA experts on the call with reporters. However, the very first question—and for any space reporter, the obvious one—concerned NASA’s on-again, off-again plan to return rocks from the surface of Mars for study on Earth. This mission, called Mars Sample Return, has been on hold for nearly two years after an independent analysis found that NASA’s bloated plan would cost at least $8 billion to $11 billion. President Trump has sought to cancel it outright.

Duffy faces the space press

“What’s the latest on NASA’s plans to retrieve the samples from Perseverance?” asked Marcia Dunn, a reporter with the Associated Press, about small vials of rocks collected by the NASA rover on Mars.

“So listen, we’re looking at how we get this sample back, or other samples back,” Duffy replied. “What we’re going to do is look at our budget, so we look at our timing, and you know, how do we spend money better? And you know, what technology do we have to get samples back more quickly? And so that’s a current analysis that’s happening right now.”

A couple of questions later, Ken Chang, a science reporter with The New York Times, asked Duffy why President Trump’s budget request called for the cancellation of Mars Sample Return and whether that was still the president’s intent.

“I want to be really clear,” Duffy replied. “This is a 30-year process that NASA has undertaken. President Trump didn’t say, ‘Hey, let’s forget about Mars.’ No, we’re continuing our exploration. And by the way, we’ve been very clear under this president that we don’t want to just bring samples back from Mars. We want to send our boots to the Moon and to Mars, and that is the work that we’re doing. Amit (Kshatriya, the new associate administrator of NASA) even said maybe we’ll send our equipment to test this sample to Mars itself. All options are on the table.”

Child dies of horrifying measles complication in Los Angeles

A child in Los Angeles has died of a measles-related brain disorder stemming from an infection in infancy, the Los Angeles County health department reported Thursday.

Specifically, the child died of subacute sclerosing panencephalitis (SSPE), a rare but always fatal complication that strikes years after an initial measles infection. The health department’s announcement offered few details about the child, including the child’s age, but said that the child had contracted the virus before they were old enough to be vaccinated against measles. The first of two recommended doses of measles, mumps, and rubella (MMR) vaccine is given between 12 and 15 months.

“This case is a painful reminder of how dangerous measles can be, especially for our most vulnerable community members,” Muntu Davis, a Los Angeles County health officer, said in a statement. “Infants too young to be vaccinated rely on all of us to help protect them through community immunity. Vaccination is not just about protecting yourself—it’s about protecting your family, your neighbors, and especially children who are too young to be vaccinated.”

SSPE is caused by a persistent measles infection in the central nervous system. Children infected with the virus may go through the standard disease progression—flu-like symptoms, high fever, the telltale rash—and then appear to fully recover. But, for a small few, the virus remains, and SSPE emerges years later, often seven to 10 years after the initial infection.

The Los Angeles health department noted that SSPE generally affects about 1 in 10,000 people with measles, but the risk may be much higher—about 1 in 600—for those who get measles as infants, such as the child who recently died.

With widespread vaccination, which led to measles being declared eliminated from the US in 2000, SSPE has virtually disappeared in the US. However, with vaccination rates slipping and anti-vaccine misinformation and views gripping the country, health experts fear seeing more of these devastating cases. Already, the US measles case count for the year is at a 33-year high, and two other children, as well as an adult, died from the acute infection this year.

The US is now the largest investor in commercial spyware

Paragon, responding to the committee’s findings, accused Italian authorities of refusing to conduct a thorough technical verification—an assessment it argued could have resolved the issue.

Apart from focusing on investment, the Atlantic Council notes that the global spyware market is “growing and evolving,” with its dataset expanded to include four new vendors, seven new resellers or brokers, 10 new suppliers, and 55 new individuals linked to the industry.

Newly identified vendors include Israel’s Bindecy and Italy’s SIO. Among the resellers are front companies connected to NSO products, such as Panama’s KBH and Mexico’s Comercializadora de Soluciones Integrales Mecale, as highlighted by the Mexican government. New suppliers named include the UK’s Coretech Security and UAE’s ZeroZenX.

The report highlights the central role that these resellers and brokers play, stating that it is “a notably under-researched set of actors.” According to the report, “These entities act as intermediaries, obscuring the connections between vendors, suppliers, and buyers. Oftentimes, intermediaries connect vendors to new regional markets.”

“This creates an expanded and opaque spyware supply chain, which makes corporate structures, jurisdictional arbitrage, and ultimately accountability measures a challenge to disentangle,” Sarah Graham, who coauthored the report, tells WIRED.

“Despite this, resellers and brokers are not a current feature of policy responses,” she says.

The study reveals the addition of three new countries linked to spyware activity—Japan, Malaysia, and Panama. Japan in particular is a signatory to international efforts to curb spyware abuse, including the Joint Statement on Efforts to Counter the Proliferation and Misuse of Commercial Spyware and the Pall Mall Process Code of Practice for States.

“The discovery of entities operating in new jurisdictions, like Japan, highlights potential conflicts of interest between international commitments and market dynamics,” Graham says.

Despite efforts by the Biden administration to constrain the spyware market through its executive order, trade and visa restrictions, and sanctions, the industry has continued to operate largely without restraint.

senator-blasts-microsoft-for-making-default-windows-vulnerable-to-“kerberoasting”

Senator blasts Microsoft for making default Windows vulnerable to “Kerberoasting”

Wyden said his office’s investigation into the Ascension breach found that the ransomware attackers’ initial entry into the health giant’s network was the infection of a contractor’s laptop after using Microsoft Edge to search Microsoft’s Bing site. The attackers were then able to expand their hold by attacking Ascension’s Active Directory and abusing its privileged access to push malware to thousands of other machines inside the network. The means for doing so, Wyden said: Kerberoasting.

“Microsoft has become like an arsonist”

“Microsoft’s continued support for the ancient, insecure RC4 encryption technology needlessly exposes its customers to ransomware and other cyber threats by enabling hackers that have gained access to any computer on a corporate network to crack the passwords of privileged accounts used by administrators,” Wyden wrote. “According to Microsoft, this threat can be mitigated by setting long passwords that are at least 14 characters long, but Microsoft’s software does not require such a password length for privileged accounts.”

Additionally, Green noted, the continuing speed of GPUs means that even when passwords appear to be strong, they can still fall to offline cracking attacks. That’s because the security cryptographic hashes created by default RC4/Kerberos use no cryptographic salt and a single iteration of the MD4 algorithm. The combination means an offline cracking attack can make billions of guesses per second, a thousandfold advantage over the same password hashed by non-Kerberos authentication methods.

Referring to the Active Directory default, Green wrote:

It’s actually a terrible design that should have been done away with decades ago. We should not build systems where any random attacker who compromises a single employee laptop can ask for a message encrypted under a critical password! This basically invites offline cracking attacks, which do not need even to be executed on the compromised laptop—they can be exported out of the network to another location and performed using GPUs and other hardware.

More than 11 months after announcing its plans to deprecate RC4/Kerberos, the company has provided no timeline for doing so. What’s more, Wyden said, the announcement was made in a “highly technical blog post on an obscure area of the company’s website on a Friday afternoon.” Wyden also criticized Microsoft for declining to “explicitly warn its customers that they are vulnerable to the Kerberoasting hacking technique unless they change the default settings chosen by Microsoft.”

One of Google’s new Pixel 10 AI features has already been removed

Google is one of the most ardent proponents of generative AI technology, as evidenced by the recent launch of the Pixel 10 series. The phones were announced with more than 20 new AI experiences, according to Google. However, one of them is already being pulled from the company’s phones. If you go looking for your Daily Hub, you may be disappointed. Not that disappointed, though, as it has been pulled because it didn’t do very much.

Many of Google’s new AI features only make themselves known in specific circumstances, for example when Magic Cue finds an opportunity to suggest an address or calendar appointment based on your screen context. The Daily Hub, on the other hand, asserted itself multiple times throughout the day. It appeared at the top of the Google Discover feed, as well as in the At a Glance widget right at the top of the home screen.

Just a few weeks after release, Google has pulled the Daily Hub preview from Pixel 10 devices. You will no longer see it in Google Discover nor in the home screen widget. After being spotted by 9to5Google, the company has issued a statement explaining its plans.

“To ensure the best possible experience on Pixel, we’re temporarily pausing the public preview of Daily Hub for users. Our teams are actively working to enhance its performance and refine the personalized experience. We look forward to reintroducing an improved Daily Hub when it’s ready,” a Google spokesperson said.

Microsoft ends OpenAI exclusivity in Office, adds rival Anthropic

Microsoft’s Office 365 suite will soon incorporate AI models from Anthropic alongside existing OpenAI technology, The Information reported, ending years of exclusive reliance on OpenAI for generative AI features across Word, Excel, PowerPoint, and Outlook.

The shift reportedly follows internal testing that revealed Anthropic’s Claude Sonnet 4 model excels at specific Office tasks where OpenAI’s models fall short, particularly in visual design and spreadsheet automation, according to sources familiar with the project cited by The Information, who stressed the move is not a negotiating tactic.

Anthropic did not immediately respond to Ars Technica’s request for comment.

In an unusual arrangement showing the tangled alliances of the AI industry, Microsoft will reportedly purchase access to Anthropic’s models through Amazon Web Services—both a cloud computing rival and one of Anthropic’s major investors. The integration is expected to be announced within weeks, with subscription pricing for Office’s AI tools remaining unchanged, the report says.

Microsoft maintains that its OpenAI relationship remains intact. “As we’ve said, OpenAI will continue to be our partner on frontier models and we remain committed to our long-term partnership,” a Microsoft spokesperson told Reuters following the report. The tech giant has poured over $13 billion into OpenAI to date and is currently negotiating terms for continued access to OpenAI’s models amid ongoing negotiations about their partnership terms.

Stretching back to 2019, Microsoft’s tight partnership with OpenAI until recently gave the tech giant a head start in AI assistants based on language models, allowing for a rapid (though bumpy) deployment of OpenAI-technology-based features in Bing search and the rollout of Copilot assistants throughout its software ecosystem. It’s worth noting, however, that a recent report from the UK government found no clear productivity boost from using Copilot AI in daily work tasks among study participants.

ai-vs.-maga:-populists-alarmed-by-trump’s-embrace-of-ai,-big-tech

AI vs. MAGA: Populists alarmed by Trump’s embrace of AI, Big Tech

Some Republicans are still angry over the deplatforming of Trump by tech executives once known for their progressive politics. They had been joined by a “vocal and growing group of conservatives who are fundamentally suspicious of the benefits of technological innovation,” Thierer said.

With MAGA skeptics on one side and Big Tech allies of the president on the other, a “battle for the soul of the conservative movement” is under way.

Popular resentment is now a threat to Trump’s Republican Party, warn some of its biggest supporters—especially if AI begins displacing jobs as many of its exponents suggest.

“You can displace farm workers—what are they going to do about it? You can displace factory workers—they will just kill themselves with drugs and fast food,” Tucker Carlson, one of the MAGA movement’s most prominent media figures, told a tech conference on Monday.

“If you do that to lawyers and non-profit sector employees, you will get a revolution.”

It made Trump’s embrace of Silicon Valley bosses a “significant risk” for his administration ahead of next year’s midterm elections, a leading Republican strategist said.

“It’s a real double-edged sword—the administration is forced to embrace [AI] because if the US is not the leader in AI, China will be,” the strategist said, echoing the kind of argument made by Sacks and fellow Trump adviser Michael Kratsios for their AI policy platform.

“But you could see unemployment spiking over the next year,” the strategist said.

Other MAGA supporters are urging Trump to tone down at least his public cheerleading for an AI sector so many of them consider a threat.

“The pressure that is being placed on conservatives to fall in line… is a recipe for discontent,” said Toscano.

By courting AI bosses, the Republican Party, which claims to represent the pro-family movement, religious communities, and American workers, appeared to be embracing those who are antithetical to all of those groups, he warned.

“The current view of things suggests that the most important members of the party are those that are from Silicon Valley,” Toscano said.

childhood-and-education-#14:-the-war-on-education

Childhood and Education #14: The War On Education

The purported main purpose of school, and even of childhood, is educating children.

Many people are actively opposed to this idea.

Either they have other priorities that matter more, or sometimes they outright think that your child learning things is bad and you should feel bad for wanting that.

Some even say it openly. They actively and openly want to stop your child from learning things, and want to put your child into settings where they will not learn things. And they say that this is good.

Or they simply assert that the primary point of education is as a positional good, where what matters is your relative standing. And then they pretend this doesn’t imply they both should and are going around preventing children from learning.

In other places, we simply epicly fail at education and don’t seem to care. Or education ‘experts’ claim that things that obviously work don’t work, or things that obviously don’t work, do work.

Consider this section some combination of peek into this alternative universe of thought and the fun of multiple meta levels of shooting fish in a barrel?

I present, HT to Pamela Hobart who makes many of the same points: Freddie DeBoer writes the long ‘Education Doesn’t Work 3.0’ which is ‘a comprehensive argument that education cannot close academic gaps.’

What? Was it supposed to do that? Would you want it to?

Very obviously the only way to close academic gaps fully is to go all handicapper general and ban bright kids from getting educations. Thus, The War on Education.

Freddie starts off saying we can’t admit some kids aren’t smart, and some kids will naturally do better at school than others, to which I say you just admitted it, and I’m happy to admit it, and everyone I talk to is willing to admit it, so who is this mysterious we. It is, presumably, a Certain Type of Guy who is an ‘education expert’ of some kind and presumably has a maximum of one child who has gone to school.

Freddie DeBoer: Our educational debates are largely useless because most people engaged in those debates assume out of hand that, absent unusual circumstances like severe neglect or abuse or the presence of developmental or cognitive disabilities, any student can be taught to any level of academic success, and any failure to induce academic success in students is the result of some sort of unfortunate error.

Well, it depends.

If you mean ‘those debates’ as in those between those ‘education experts’? Then perhaps yes, they make these types of absurdly stupid assumptions. If you mean ‘debates among actual regular humans,’ then no. Obviously not. One would question whether Freddie has met such people.

Education can raise the absolute performance of most students modestly, but it almost never meaningfully reshuffles the relative distribution of ability and achievement.

Um, again, what exactly were we trying to do? Educate the children? Or make sure we don’t educate the children? Half and half?

I mean, I guess Freddie then does a job repeatedly exposing ‘the contradictions’ as it were in the entire equality project, but the barrel already has a lot of bullet holes, the water is leaking and the fish are dead.

So we get more fun lines like this:

We have spent an immense amount of effort, manpower, time, and treasure on forcing students to meet procrustean academic standards, despite the fact that we have overwhelming evidence that their relative performance is largely fixed.

Yes, obviously, also yes the extra money is mostly being wasted but even if it wasn’t the whole point was presumably to (drum roll) educate the children.

Why in the world would we spend tons of resources and time on relative education, which by definition is zero sum and a red queen’s race? That doesn’t make sense. There’s a fixed amount of relative education.

At the end of this essay, I will argue that education is important, does matter, and is worth funding – but that what’s now assumed to be its primary purpose, moving students around in quantitative educational metrics, is actually what education does worst.

Who thought that was its primary purpose, either the metrics or the thing itself?

Meanwhile, the reason this was brought to my attention is that his ‘absolute learning has value’ t-shirt is raising questions supposedly answered by the shirt:

What This Essay Does Not Argue:

  • That absolute learning (that is, learning as measured against a standard or benchmark or criterion) has no value; rather, relative learning is practically and morally dominant in these discussions because only relative learning (sometimes discussed in terms of educational mobility) can better one’s economic fortunes, and it is that potential that underlies our entire modern educational debates and the reason for obsession with achievement gaps.

The next section is ‘I Assure You, You Do Care About Relative Learning.’

I assure him that I don’t.

His first argument is that relative learning indicates absolute learning. That is true but saying this means therefore you care about relative learning (checkmate, liberals?) is not how logic or words work. Caring about the territory does not mean you care about the (not very accurate) map.

Second, while I am happy to concede that absolute learning happens all the time, this should not be mistaken for saying that absolute learning is easily achieved, reliable, or consistent.

I don’t understand why this is supposed to be a relevant argument here. It seems like he’s saying I care about [X], but actually [X] is hard, so instead I care about [Y]?

Most importantly, though, is a simple reality: the consequences of education are derived from relative performance, not absolute.

In the vast majority of scenarios where education is relevant, applicants of whatever type are being evaluated relative to peers.

There’s saying the quiet part out loud, and then there’s this.

The purpose of education is… to do well on applications?

He concedes that one might learn to drive and then use this skill to usefully operate a moving vehicle, but says this type of education is rare – that most education has no actual use whatsoever, other than as a positional good to grab a larger share of stuff.

Then he goes through that schools are ‘not guilty’ because improving educational outcomes is impossible anyway. Transferring does nothing. Charter schools don’t work. Interventions don’t work (literally “Nothing “Works””), full null hypothesis.

All right, so now we have a section ‘So What Should We Do?’

Very obviously, if you actually believed all that, you would want to dramatically reduce spending, both in money and in the time of children, on school, since school is almost entirely about relative position. Spending more on school, trying to achieve more or improve performance, in this model, is a defection against everyone else. So we should ban attempts to educate children, beyond some basic skills, and focus on practical stuff like learning to drive. Completely reorient childhood.

So having pre registered that, let’s see what he recommends.

  1. Improve air quality. Okay, sure, that is one of the somethings that work, although again I don’t understand why he thinks improving performance is good.

  2. Lower our educational standards. Don’t make kids learn (for example) abstract math. Yes, that makes perfect sense for Freddie, if the learning is useless, you shouldn’t require it. Again, if he is right then we should go farther, and ban such learning. Why are we letting kids engage in a zero sum competition?

  3. Soft tracking. Again, good idea, not sure what it has to do with the post.

  4. Invest in a robust safety net. Maybe? That’s a different department.

Then he tries to pivot back to ‘actually education matters.’

Education creates the conditions for children and young adults to discover ideas, literature, science, and art that might otherwise remain inaccessible.

It provides the structured time and social environment where curiosity can blossom, where students can learn how to think about problems that don’t have easy answers, and where they can build lasting relationships with peers and mentors.

The point of school, then, is not to guarantee that every child climbs into the top decile of performance but to offer each student the chance to cultivate knowledge, resilience, and imagination in ways that enrich their lives.

So absolute learning of something does matter after all, then. I mean, this description does not match what I know about actual schools, nor would I design anything like a current school if those were the goals. And he doesn’t seem interested in a redesign or asking how to maximize the things that he thinks matter. But hey.

Meanwhile, here’s the top comment, so yes things do get pretty insane:

James K: This is what I pay you for, Freddie, thank you for being so clear-headed about this topic.

I’ve been teaching for 16 years now and it boggles my mind that the band teacher can literally get on stage and say “We have the beginner, intermediate, and advanced band for you” and of course the baseball team can be divided into Varsity and JV, but I am not allowed to say that some kids are not smart enough to handle my AP classes because this means I don’t BELIEVE IN THEM or am supporting TRACKING (always said in the tones people reserve for the words ‘eugenics’ or ‘segregation’).

I mean, yes. It means you support tracking because tracking is good. It means you don’t believe in them in the sense that you don’t believe in things that aren’t real.

So no, in that sense Freddie isn’t arguing with a strawman. Which means that the entire system of education is being run by people who are at war with education.

A Tennessee teen is suing his school for ‘compensatory education’ after graduating with a 3.4 GPA, but being unable to read, or even spell his own name, and the school system has the audacity to defend against that lawsuit.

But the school took no action, the suit says, other than giving him 24 hours to complete his assignments.

But even this “solution” was a problem. Because when William was at home with his schoolwork, he relied on AI programs like ChatGPT and Grammarly to complete his assignments for him, according to the judge who ruled on his suit last week. As a result, William continued to achieve high marks on his classwork throughout his entire four years of high school, even though teachers knew he was illiterate.

If you can’t read, using ChatGPT is kind of crazy – you’re presumably scanning or copy pasting in text you don’t understand, then copying out text you don’t understand and hoping for the best.

Scott Alexander asks: What happened to NAEP Scores? He says they are ‘not good’:

Well, they’re not great obviously, to the extent you can trust the scores to map to Reality, but they are still above the start of the graph in 1998, and we’re talking about a seven point difference. That’s less than a fifth of a standard deviation. This is nothing, if anything this shows that Covid didn’t change things much?

The comments section of Scott’s post is full of despair about classroom conditions getting worse, shifts to teaching strategies that don’t work (see the Mississippi reforms but in reverse), discipline collapsing and teachers having no tools if kids don’t play along, many teachers quitting, chronic absenteeism happening and being accepted and tolerated, and many families not prioritizing education, on top of the continuing trends involving smartphones. That’s on top of the obvious ‘Covid took away a lot of schooling’ concern that Scott starts with.

What seems more meaningful than the overall smaller drop is the widening gap between low and high performers, another trend predating Covid. Scott has several graphs showing this, and I am convinced this is real, with a variety of causes. If you are properly equipped and motivated, you can avoid the pitfalls described above, and you have access to the entire web and world and a lot of new resources, now even including AI. Whereas when the bottom falls out, the bottom falls out.

Meanwhile in 12th grade, nearly half scored below ‘the basic level,’ which involves things like ‘using percentages to solve real-world problems,’ and reading scores hit a new low. What we are doing, including adding funding, is clearly not working. Or rather, it is working hard, only not at the goal of children learning academic skills.

The War on Algebra in particular is still perhaps the craziest thing I’ve ever seen, actively preventing children from learning math out of spite. In the sense that it both very clearly purely destructive and evil, and also horribly unpopular across the board, and also high salience to a lot of voters. Yes, I do know what their arguments are for doing it, and they very much do not make it any better.

And yet it still happened, and it happens across the board, straight up Handicapper General style.

Ro Khanna: It is absurd that Palo Alto School district just voted to remove honors biology for all students & already removed honors English. They call it de-laning. I call it an assault on excellence. I took many honors classes at Council Rock High in PA.

Autumn Looijen: I ran the campaign to bring algebra back to SF’s middle schools.

It was the most popular thing I ever worked on. Voters don’t want to take away opportunities for kids who can’t afford private school.

If anyone wants to put this on the ballot in Palo Alto, happy to advise.

Maud Maron: We are trying to do a version of this in NYC! Would love to have you speak to NYC parents who want to have algebra & geometry options in Middle School.

Meanwhile in San Francisco, the war rages on. It seems the city has not yet been retaken by sanity on all fronts yet, although there are some promising signs. All of this seems like it has to be beyond unpopular, in a ‘cause families to move out’ way, yet here we were again not too long ago (it got better, for now):

Garry Tan: San Francisco schools is trying its absolute hardest to make sure all middle income families who could move out of the city do so right away.

“Grading for Equity” is going to be a real disaster and I guess this is a boon for SF private schools and Burlingame housing prices.

For education bureaucrats who ruin our public schools with the most unfair and anti-merit polices: BUSINESS IS BOOMING.

Someone needs to investigate the Schools of Education that spawn these policies because it is a real danger to public schools everywhere.

Basically this scam is Idiocracy in real life.

Mike Solana: the san francisco board of education must immediately fire the superintendent. if they do not, they must all be removed from power.

I don’t get how this falls under ‘you can just do things’ but it seems it did, at least until people sounded the alarm?

John Trasvina (The Voice of SF): Without seeking approval of the San Francisco Board of Education, Superintendent of Schools Maria Su plans to unveil a new Grading for Equity plan on Tuesday that will go into effect this fall at 14 high schools and cover over 10,000 students.

The school district is already negotiating with an outside consultant to train teachers in August in a system that awards a passing C grade to as low as a score of 41 on a 100-point exam.

Were it not for an intrepid school board member, the drastic change in grading with implications for college admissions and career readiness would have gone unnoticed and unexplained. It is buried in a three-word phrase on the last page of a PowerPoint presentation embedded in the school board meeting’s 25-page agenda.

Grading for Equity eliminates homework or weekly tests from being counted in a student’s final semester grade. All that matters is how the student scores on a final examination, which can be taken multiple times.

Under the San Leandro Unified School District’s grading for equity system touted by the San Francisco Unified School District and its consultant, a student with a score as low as 80 can attain an A and as low as 21 can pass with a D.

Derek Thompson: New SF public school plan would

– eliminate homework and weekly tests from counting toward semester grade

– allow students to take the final exam multiple times

– convert all B grades into As, and all Fs into Cs

It’s hard to see the difference between this policy and what you’d get if a bunch of 10yos locked the teachers in a closet and rewrote the rules.

Karen Vaites: More media attention here, please! 🚩🚩🚩

Jared Walczak: The sad irony is that Grading for Equity is virtually the opposite of Teaching for Equity, because under this system, the only kids who might get a real education are those from families that take more into their own hands, bringing higher expectations and resources to bear.

So, effectively no grading, then. You can do whatever you want all semester, no homework (so perhaps there’s some upside here?), phone out in class every day, whatever, all you have to do to pass is get 21% on an exam you can take multiple times. That was going to be it.

And Maria Su could just do this on her own? What?

It turns out that enough backlash does matter, and this combination of graft and civilizational suicide took the loss on this one.

SF Standard: Just in: SFUSD is delaying a planned “grading for equity” initiative after the proposal sparked furious backlash.

Kelsey Piper: SF superintendent backed off immediately after the flood of negative feedback. This strikes me as a pretty dramatic change from how previous standards erosions were received, and a really good sign.

Most politicians want to make their constituents happy, and often their information environment is kind of terrible for that. It’s worth advocating for the stuff that matters to you. Don’t be an asshole, but be clear and outspoken.

San Francisco’s turnaround happened very fast. The Bay Area could become one of the best-governed parts of the United States inside a few years if we work to make it happen.

Well, maybe. They say they are ‘delaying’ the initiative. Which means they’re presumably going to keep paying the consultants, and they are going to try again to destroy all the incentives and measurements involved in education.

Fighting against algebra and grading is bad enough, but reading?

As in, people who want to ban teaching kids to read until age 6. No. Seriously.

Because they’re ‘not ready.’

Erik Hoel: 62% of American kids have a tablet at age 6.

They spend 3.5 hours every day on screens (increasingly, TikTok).

And because our school system waits so long to teach reading, they never get a chance to become readers.

“Education experts” have been saying for decades that we must wait to start teaching reading until 6-7 for neuroscientific reasons. These reasons appear, as far as I can tell, to be basically made up. Consider this recent article, which quotes a bunch of experts on this.

E.g., Maryanne Wolf says that brain myelination needs to reach a certain stage, and that teaching reading prior to 5 is “really wrong” and that she would ban teaching reading prior to 6 nationwide if she could.

Siberian Fox: what in the fuck

I was playing Pokémon before 6 if I recall correctly, if not, other games that require reading

good to know that there are people in the US that think this should be super illegal

In a good school, a 1st grader will be reading quite a lot, actually.

I’m not going to bother quoting more of the evidence because this is so utterly Obvious Nonsense as to be beyond belief. Frankly, if I had a child that was 6 years old and couldn’t read I would not be thinking ‘good it is finally time,’ I would be debating exactly how much to panic and reassuring my wife not to panic far more.

The 3 year old I am currently supervising can somewhat read. I could read before my first memory (which was at 5 and involves reading books) so I don’t know exactly when it happened, and I learned without anyone trying to teach me.

I am going maximum opposite. There is no higher priority than teaching a child to read as early as they can handle it, and every actual parent knows this. There is a reason why the advice is constantly read to them, read with them, push reading. Reading enables everything else. The entire ‘education’ establishment really does need to flat out join the delenda est club.

In the name of them developing empathy for the people you force them to teach? As long as they pass a certain threshold of knowledge, the rest of their childhood, and indeed life, belongs to the people, and they’re a horrible person if they think otherwise, and the purpose of school is to teach them this?

No, seriously, this is something quite a lot of people, especially those in education, actually believe.

Setting all ethical or moral considerations aside, and even assuming that is the goal, what in the world makes you think this is going to work in the direction you want?

Tracing Woods: If a child is in a class, they should be there because it is the best environment to help them learn, not so they can act as an unpaid tutor to provide vague “peer effects” to others A system that abuses children as resources instead of teaching them to their level is unethical.

Joe McReynolds (3.4m views): That’s what life *is*, though! If you’re unusually smart/talented, your primary purpose in life is to help lift up others who weren’t born/raised as lucky as you were. Learning that sooner rather than later is important for developing a sense of altruism and communitarianism.

“With great power comes great responsibility” is a simple, true statement. To the extent being born with unusual (intellectual) power is an “innate characteristic,” that good luck means that you owe the universe hard work. You’re born with a debt that takes a lifetime to repay.

There it is, very explicitly. These people actually believe this. If you’re talented, your purpose in life is to be enslaved, to be forced to help others. Your life does not belong to you. Your labor does not belong to you. Your time does not belong to you. Who cares whether that benefits you? You belong to the people, from each according to their ability, at the barrel of a gun.

Kelsey Piper: If I were actively trying to extinguish my children’s sense of altruism, compassion and responsibility I can’t think of a better plan than forcing them to spend all of their time doing random ‘altruistic’ chores they didn’t choose, and aren’t equipped to succeed at.

If you say to your kid “I’m going to volunteer this weekend to help socialize cats”, they’ll probably come along and they may discover a lifelong love of helping animals! if you force them to spend all their time on it, guess what, they’re gonna hate it.

if you want your children to be people who give generously to their communities and their broader world, be that kind of person yourself and let them witness the ways in which this is part of the good for you and for your community.

SteelBlaidd: Why do they need to go to college to learn to be teachers if kids can be expected to do it in elementary school?

Kelsey Piper: some people out here believe that homeschooling is immoral since you don’t know enough to teach your kids and also that a smart 9 yo can do it.

Ben Hoffman: The important thing is that the 9yo is forced to do it without pay to teach them that being educated means going along with nonsense dramas, which qualifies them to get paid to go along with nonsense dramas when old enough that that’s dramatically appropriate.

Not only that the smart 9you can do it, that they should be forced to do it without pay. While the parent is forbidden to do it, because they are unqualified.

Ryan Moulton (QTing Joe above): Everybody is dunking on this, and I get why, but I’m a little more sympathetic. Particularly in lower grades, developing empathy for people different from you or dumber than you is a really important thing to get out of school, comparably important to getting through math faster.

Sarah Constantin: t is super common for kids to openly taunt anyone who’s not as good as them (at anything!) and i do think it’s important for them to learn manners, grace, and sportsmanship…

but it doesn’t deserve as much time in the day as math class.

Gallabytes: I would add that these kinds of assignments don’t necessarily breed empathy it’s pretty easy for it to create contempt instead.

Sarah Constantin: yeahhh.

Gallabytes: feels like people talk about school in far mode as some inscrutable thing.

if I put *youin a room with people you had 4 sigma on and told you to teach them math Or Else, how would you feel? how would this make you feel about them?

I believe we should treat Joe’s perspective the same way we would treat others who would force people with certain characteristics to labor for no compensation.

See my discussion of Alpha School for extensive previous discussions.

Tracing Woods (reference documents and more details in thread): in 1930, researchers studied ability grouping and concluded you needed to adjust the curriculum to make it work

in 1960, more confidently so

then in 1990, they studied grouping without changing curriculum, concluded it was useless, and advocated to get rid of ability grouping

over time the field got better and better at studying the form of ability grouping that everybody had known was pointless for sixty years while just sorta disregarding the form that kept getting results

I get so mad every time I read this stupid study

the field of education set itself back generations because it kept listening to people who thought ability grouping was “antidemocratic and antiegalitarian” and as such badly wanted it not to work

we had it figured out in 1936 and then we threw it away for kicks.

I am not a fan of the idea of educating children in 2025 primary via traditional classes. Traditional classes feel like learning a lot more than they actually cause learning.

But I accept that we are going to keep doing this for a while.

Given you are going to have traditionally shaped classes on various subjects, very obviously you want to track their progress and group those children by ability.

Grouping children into classes by ability has the advantages that it, as covered in Education #11:

  1. Helps almost all children learn more, whether they are behind, ahead or neither. There are some corner cases where kids are ‘on the bubble’ between tracks, or get tracked wrong, but mostly this is opportunity cost, that they missed benefits.

  2. Is universally popular with parents, to the extent that ‘ending tracking’ is the least popular serious policy proposal we have ever seen. As in David Shor says ‘removing advanced classes from schools’ is literally the single most unpopular policy Blue Rose has ever polled (yet there goes Palo Alto doing exactly this.)

  3. Is even popular with the classroom teachers themselves.

Ability grouping, done wisely, so utterly obviously works as to make the alternate hypothesis absurd.

Tracing Woods: will someone struggling with basic arithmetic and someone who knows calculus benefit from the same instruction? no.

would selective schools and the students in them benefit from opening their doors to everyone? they certainly don’t seem to think so!

do athletics orgs advocate grouping young LeBron into his local mixed-ability rec league so he can trarin and progress? no.

do gifted kids who accelerate learn more advanced material when they’re presented with it? yes.

if people see school as a democratic equalizer where everyone should learn the same things, they find ability grouping doesn’t work (doesn’t accomplish that goal). if people see school as a place where people should learn specific subjects and progess to whatever level they can, they find it does work (does accomplish that goal). and because education research is dominated by the former, onlookers glance at its output and say “huh, the results are mixed. guess we’ll never know!”

there is no substitute for understanding what is going on at a ground level.

The question is how to make it work best, not whether it works. Very obviously, as the next section discusses, it is possible to massively screw it up if you try hard enough.

Jordan Michelson: Why would *teacher’s unionsoppose ability grouping? It makes no sense.

Matthew Yglesias: Ideology.

Karen Vaites: The average American would be shocked by the degree to which K-12 education is ruled by ideology. Beliefs about teaching and how we want learning to work often trump evidence about what does, in fact, work.

Tracing Woods: “Trace, why are you making such a big deal out of something everybody already agrees with?”

Because the people we trust to direct society on this topic at every level oppose it.

And I hope that maybe if I shout enough about that people will really internalize what that means.

Exactly. Everyone agrees we want [X], where [X] is tracking. We keep talking about it because [~X] keeps actually happening.

I presume opposition is mostly ideology. Full stop. They want to prevent the wrong kids learning too much. They are sacrificing the kids on their alter.

Academics and education ‘experts,’ despite the literature and all actual observations and everyone involved saying that tracking helps all kids learn better, keep lamenting that parents want tracking, and work to destroy it, often in the name of ‘equity.’

It is common to see people claim ‘the research’ says that ‘downstreamed’ kids who are grouped at lower ability do worse rather than better as a result and that ‘the research’ supports this. As far as I can tell this is simply not true, these people simply think it ‘should’ be true, and seek out ways to say it anyway.

Tracing Woods: what happens when academics study parental perception of ability grouping?

They lament that parents of students at all levels favor it even though it’s BAD.

Virtually no parents support ending ability grouping.

Parents of kids in both remedial and G/T programs agreed that their kids should be grouped with kids of equal ability

80% of special-ed parents, 90% of parents with kids in remedial courses, and 98% of parents with kids in advanced programs agreed that their kids were helped by it.

This was all very disappointing to the authors.

Why do the authors here, like many other academics and education experts and many school principals who somehow end up actually destroying such programs, say that this is bad, despite everyone involved in the actual schools agreeing it helps all of the students?

Because the ‘educators’ who determine policy (as opposed to the teachers whose job is to actually educate children) consistently have decided that they do not care about the life experiences of families and children or helping children learn.

What they care about, other than money, is preventing learning rather than causing learning. Or, as they call it, ‘equality’ or ‘equity.’ Never mind that this ‘equity’ directly hurts the students who are otherwise being ‘denied’ it, what matters is that they be given ‘opportunity to learn and equality of educational opportunity.’ Educational opportunity shall be destroyed until this is achieved. If that leads to everyone getting a worse education, even the worst off kids, well, that’s not their department’s KPI.

I don’t quite agree with Anton that these people ‘hate you and your children.’ They only hate that you and your children might do better than other children, and want to prevent this from happening. They only hate you if you oppose this goal.

Garry Tan: Ability grouping in school (honors/AP) depends on your frame. If school’s job is to equalize, grouping looks like a fail. If it’s to let kids sprint ahead, it works.

Academia worships equalizing— so the School of Education bureaucrats become anti-education, ruining schools.

When you examine the list of nonprofits and academics that want to remove advanced math from classrooms and water down the standards for all students it will leave you shaken.

It’s not a fringe movement. It is School of Education Orthodoxy.

Tracing Woods: This is a fair question! Opposition to ability grouping is a fringe idea opposed by the great majority of parents. So which obscure, fringe organizations are pushing it?

Let’s ask the National Council of Teachers of English what they think:

Or what about the most prominent law casebook publishers?

Or consider the National Association of Secondary School Principals.

How about the Association of State

Supervisors of Mathematics, NCSM: Leadership in

Mathematics Education, and the National Council of Teachers of Mathematics (NCTM)?

You know it.

If it is a choice between the form of academia that wants to prevent children from learning, and the form of academia that helps teach useful things, and one or the other must be destroyed?

The choice seems clear.

Tracing Woods: my modest proposal to every university that has published research claiming ability grouping (with paired curricular modification) doesn’t work:

detrack. remove your admissions standards. remove course prerequisites.

if detracking works, let’s create Harvard Community College.

However, you do have to choose a reasonable implementation. Is it possible we also in some ways are screwing implementation up so badly that adding what we call ability grouping to the mix, as implemented in practice, could make things worse?

North Carolina excluded half its qualified students from advanced math. They tried to pass a law to fix some of this. The schools fought back.

Tracing Woods: What happened when North Carolina changed its laws to require top-scoring students to be placed in advanced math?

The state board of education changed the test cutoffs, subverting the intent of the law by dropping almost all students from the top-scoring category.

Janet Johnson and John Wittle: The law was intended to help high school students who excelled in their math classes move into the advanced track. Before the scoring change, 11% of high school students statewide scored at Level 5, the highest level, with some districts seeing rates as high as 25%. The EVAAS Prediction vs. Performance table (above) showed that in 2009, 42,144 students were predicted to be successful in 8th-grade algebra, and only 18,670 students were enrolled. Using EVAAS prediction as the metric would have given 23,474 more students access to advanced math.

After the law passed, which required schools to admit all Level 5 students to advanced classes, and the state changed the scoring scale, fewer than 1,500 (too few to report) high school students in the entire state achieved Level 5.

The schools had technically complied with the law while completely subverting its intent. These charts are from the NC School Report Cards.14 After 2019, the Math 1 Performance charts show no Level 5 and very little Level 4, similar to this.

The full post on ‘the Algebra gatekeepers’ keeps outlining all the tactics used to ensure that kids do not learn algebra, especially disadvantaged kids. As you read it, it keeps getting worse.

For example, we attended a meeting with the parents of a middle school girl who had earned an A in 7th-grade pre-algebra but was denied enrollment in 8th-grade algebra despite her and her parents’ wishes. The teachers argued that her formative assessments didn’t align with her summative performance, suggesting her previous success didn’t guarantee future outcomes.

The language arts teacher claimed the student had “appeared to struggle” during benchmark activities and that earning an A seemed “harder for her than for other students who achieved similar summative data results.” The math teacher who had given her an A pointed to C grades on some earlier formative assessments, arguing that despite her subsequent A performance on chapter tests and other summative data points, these initial benchmark scores indicated she “sometimes struggles with foundational concepts during the formative assessment process.”

The administrators nodded knowingly as teachers referenced “inconsistent performance across benchmark measures” and “concerns about the gap between formative and summative data trends.” They suggested that while her final grades represented solid summative data, the formative assessment patterns revealed “areas of concern” that made advanced placement inadvisable, regardless of what the summative data actually showed about her mastery of the subject matter. This is just an example of the kind of talk the parents encountered, so the church advocacy group started bringing someone from our staff to the meetings to help them cut through this.

This type of circular reasoning, where success was reframed as evidence of potential failure, was typical of how schools justified excluding qualified students from advanced courses.

Administrators would routinely promise that students could move to advanced tracks “later, in high school,” but our analyses and other research we found indicate students rarely moved to the advanced track after the 8th grade.

The tracking system created rigid pathways where missing 8th-grade algebra typically meant students couldn’t reach calculus by graduation, limiting their college and career options.

One fifth grader exemplified the problem. He had scored at the highest level on every test, had a 98% EVAAS prediction for success, and straight As on his report card. He was also officially classified as Academically Gifted by the school. When a new advanced math class was created, he wasn’t invited. When he asked to join, his parents were told no, he needed to be “recommended.” School officials told us, with straight faces, that his consistent past success was no indication he could succeed in advanced math, that they were keeping him out for his own good.

What North Carolina is doing here, excluding lots of qualified students, does at least seem better than ending algebra entirely for everyone, I suppose.

Pamela Hobart also looked into the same writeup and offers her own thread, notes that this steps fully into cartoon villainy.

The true teaching of algebra to kids who are ready for it is almost impossible to find. Even if you send your child to a ‘gifted’ school, they mostly won’t let kids get more than a year or two ahead of ‘schedule.’ Schools instead think it is better kids be bored for five years, for their own good you see.

Raymond Arnold points to the best objection I have seen, which is that if a more advanced option exists then many parents will push for it even when it is inappropriate for their particular child, or use it to push their child way too hard, and while this means some kids are bored it is saving a lot of families from being forced into a red queen’s race.

This is a real cost, but the prior should be rather extremely stacked against ‘if we let kids learn more then parents would try to have their kids learn too much and this would be bad,’ especially when you can gate the advanced classes with objective tests. Yes, parents can push their kids to study harder to try and pass those tests, but that’s a risk I am willing to take.

What is the steelman case that ‘ability grouping doesn’t work’ or ‘ability grouping has been tried and didn’t work’ in some particular context?

This by Karen Vaites is perhaps the closest, in particular on early reading grouping, convinced me that in practice you really can mess it up badly enough to make things actively worse. This was convincing that we’re messing up badly enough that this is a real possibility.

As in, what happens in practice is that you group kids by a measurement of abstract ‘reading level’ and then focus on ‘achievement’ of ‘reading level,’ forbid them to read anything beyond ‘reading level,’ and don’t ask what actual skills they need, don’t move them between groupings as their skills change, and then wonder why it isn’t working.

One could almost say, if you look at the details, that the teachers are using ‘reading groups’ as a substitute for actually teaching the children to read. You put them in a group and then you did your job. Again, yeah, I can see how that wouldn’t work. Indeed, if you are outsourcing the teaching job to other kids, then at that point you actively want uneven groups, because you want to group students with student teachers.

Whereas once students get to ‘escape velocity’ on reading, which the better students have relatively early, they no longer need a teacher, they just need motivation and permission to read books. Whereas the system seems designed to stop kids from reading books they want to read if they are deemed ‘too hard’? A kid can tell you if a book is too hard, they won’t want to read it.

One big complaint is that it is ‘hard to measure reading level.’ I don’t think it is hard. You can observe a lot just by watching. The problem is that you’re measuring a set of distinct reading skills as if it was one number, and then treating that one number as real, and also abdicating all the real work.

Sarah Sparks: But evidence suggests that the practice may be less beneficial than teachers think: It can exacerbate achievement gaps and even slow reading growth for some children unless the groups are fluid and focused on skills rather than overall achievement.

“What we’ve discovered is that it’s fine to have a group of students of different levels, as long as they all are working on the same learning needs,” said Carol Connor, an education professor at the University of California, Irvine, who developed the program. “You can have students of different reading abilities who all need to work on decoding. … What doesn’t work is if you put your kids who already know how to code in a group to learn how to code, again. You receive more behavior problems because they’re really bored, … and our research suggests that it has a negative effect on their growth.”

Karen Vaites: Tim Shanahan breaks down key research and its instructional implications in The Instructional Level Concept Revisited: Teaching with Complex Text. As researchers looked into the effectiveness working at reading level, studies found that it “has made no difference—that is the kids taught from grade level materials do as well as those at an instructional level—or the instructional level placements have led to less learning.”

More recently, he highlights additional new evidence from a study of third graders: “Results indicate that weaker readers, using texts at two, three, and four grade levels above their instructional levels with the assistance of lead readers [other, better reading, third graders], outscored both proficient and less proficient students in the control group across multiple measures of reading achievement.”

From a question: My daughter is in first grade. Her classroom teachers have all the books in the classroom library leveled, and students are not allowed to go beyond their reading level during “Independent” reading.

From the answer: Your daughter’s aspirations as a reader are the problem here. Some kids are allowed to read the red-dot books and others are stuck with the baby books with the blue dots. She wants to be a red dot kid, to hang with the red dot kids, to be seen as a red dot kid … but her teacher can only see her as a blue dot kid and she must learn to stay to her own bookshelf with her own kind if she is going to succeed in this classroom.

In the meantime, explain to your daughter that the teacher is trying to help her but that we teachers sometimes don’t get it right, and that you can’t always “fight city hall.”

So yes, you group primarily by what aspects the kids need to work on most, and that works better. Sure. I can totally believe that is a better strategy. Skill issue.

Instead of using it to figure out what kids need to do to learn to read and putting them in position to learn that, it sounds like grouping is being used to prevent kids from meaningfully reading? The purpose is to gate reading behind general tests? To spread ‘equality’ to progress on different reading aspects?

Sarah Sparks: It sounds like good sense. “Kids should be reading just-right texts as they grow as readers.” That just sounds sensible, doesn’t it? Many urban legends do… until you know better.

I can see why that might actively backfire. This isn’t about ‘ability grouping’ not working. It’s about failing to actually group by the relevant ability, and it’s about the ‘just-right text’ theory that seems to me obviously wrong.

Sarah Sparks: During Tier 1 instruction, you want all kids working with grade level texts; students reading below grade level will need scaffolding and support (as well as targeted Tier 2 and/or 3 intervention).

This promotes equity, for it’s the best mechanism for helping below-benchmark students to catch up.

It also honors the fact that a fifth grader who reads at second grade level is still thinking at the level of a fifth grader, and he or she will remain engaged and motivated by learning content and vocabulary at his or her developmental level. (No more baby books for big kids, y’all!)

For details on how to do this, check out:

Ignore the ‘this promotes equity’ framing, since you could simply say ‘this promotes learning to read.’ Equity via catching up those lagging is good, and you call it learning.

The theory here is that age matters a lot. That if you are a fifth grader, your ability to learn is inherently much stronger than that of a second grader, whereas the ability of different second graders is alike? Equality (of those at the same age) for me, inequality (of those at different ages) for thee. Whereas the correct model is that each kid has a different ability to learn different things, that usually improves steadily with age.

But also note that this is saying that the best way for many students at second grade reading level to learn reading is to assign them to read fifth grade level books, indeed to mandate it. Yes, I can believe that. So why are we so often telling kids at second grade reading level or literally in second grade or both that they can’t read the fifth grade books even when they want to?

The other theory present in this proposal is, how about using techniques that actually teach kids reading. And yeah, I agree, that would be great.

Tracing Woods (replying to Vaites): This is an extremely useful article that deserves a full, thorough response.

My short response is that I agree narrowly (most leveled readers seem quite bad, training specific skills matters, in-class grouping for reading is quite popular and often pretty uninspired) and disagree broadly (there is pretty strong evidence for the value of several forms of ability grouping, drawing from eg Direct Instruction, Success for All, acceleration/gifted literature; ability grouping has acquired a bad reputation for reasons mostly unrelated to its performance; “grade level” is the wrong measure) in a way that would be productive to hash out more fully.

I agree fully that the real question is cultural.

In case you didn’t realize that there is a war. There has been for a while.

Why accessibility might be AI’s biggest breakthrough

For those with visual impairments, language models can summarize visual content and reformat information. Tools like ChatGPT’s voice mode with video and Be My Eyes allow a machine to describe real-world visual scenes in ways that were impossible just a few years ago.

AI language tools may be providing unofficial stealth accommodations for students—support that doesn’t require formal diagnosis, workplace disclosure, or special equipment. Yet this informal support system comes with its own risks. Language models do confabulate—the UK Department for Business and Trade study found 22 percent of users identified false information in AI outputs—which could be particularly harmful for users relying on them for essential support.

When AI assistance becomes dependence

Beyond the workplace, the drawbacks may have a particular impact on students who use the technology. The authors of a 2025 study on students with disabilities using generative AI cautioned, “Key concerns students with disabilities had included the inaccuracy of AI answers, risks to academic integrity, and subscription cost barriers,” they wrote. Students in that study had ADHD, dyslexia, dyspraxia, and autism, with ChatGPT being the most commonly used tool.

Mistakes in AI outputs are especially pernicious because, due to grandiose visions of near-term AI technology, some people think today’s AI assistants can perform tasks that are actually far outside their scope. As research on blind users’ experiences suggested, people develop complex (sometimes flawed) mental models of how these tools work, showing the need for higher awareness of AI language model drawbacks among the general public.

For the UK government employees who participated in the initial study, these questions moved from theoretical to immediate when the pilot ended in December 2024. After that time, many participants reported difficulty readjusting to work without AI assistance—particularly those with disabilities who had come to rely on the accessibility benefits. The department hasn’t announced the next steps, leaving users in limbo. When participants report difficulty readjusting to work without AI while productivity gains remain marginal, accessibility emerges as potentially the first AI application with irreplaceable value.

In court filing, Google concedes the open web is in “rapid decline”

Advertising and the open web

Google objects to this characterization. A spokesperson calls it a “cherry-picked” line from the filing that has been misconstrued. Google’s position is that the entire passage is referring to open-web advertising rather than the open web itself. “Investments in non-open web display advertising like connected TV and retail media are growing at the expense of those in open web display advertising,” says Google.

If we assume this is true, it doesn’t exactly let Google off the hook. As AI tools have proliferated, we’ve heard from Google time and time again that traffic from search to the web is healthy. When people use the web more, Google makes more money from all those eyeballs on ads, and indeed, Google’s earnings have never been higher. However, Google isn’t just putting ads on websites—Google is also big in mobile apps. As Google’s own filings make clear, in-app ads are by far the largest growth sector in advertising. Meanwhile, time spent on non-social and non-video content is stagnant or slightly declining, and as a result, display ads on the open web earn less.

So, whether Google’s wording in the filing is meant to address the web or advertising on the web may be a distinction without a difference. If ads on websites aren’t making the big bucks, Google’s incentives will undoubtedly change. While Google says its increasingly AI-first search experience is still consistently sending traffic to websites, it has not released data to show that. If display ads are in “rapid decline,” then it’s not really in Google’s interest to continue sending traffic to non-social and non-video content. Maybe it makes more sense to keep people penned up on its platform where they can interact with its AI tools.

Of course, the web isn’t just ad-supported content—Google representatives have repeatedly trotted out the claim that Google’s crawlers have seen a 45 percent increase in indexable content since 2023. This metric, Google says, shows that open web advertising could be imploding while the web is healthy and thriving. We don’t know what kind of content is in this 45 percent, but given the timeframe cited, AI slop is a safe bet.

If the increasingly AI-heavy open web isn’t worth advertisers’ attention, is it really right to claim the web is thriving as Google so often does? Google’s filing may simply be admitting to what we all know: the open web is supported by advertising, and ads increasingly can’t pay the bills. And is that a thriving web? Not unless you count AI slop.

Nobel laureate David Baltimore dead at 87

Nobel Prize-winning molecular biologist and former Caltech president David Baltimore—who found himself at the center of controversial allegations of fraud against a co-author—has died at 87 from cancer complications. He shared the 1975 Nobel Prize in Physiology for his work upending the then-consensus that cellular information flowed only in one direction. Baltimore is survived by his wife of 57 years, biologist Alice Huang, as well as a daughter and granddaughter.

“David Baltimore’s contributions as a virologist, discerning fundamental mechanisms and applying those insights to immunology, to cancer, to AIDS, have transformed biology and medicine,” current Caltech President Thomas F. Rosenbaum said in a statement. “David’s profound influence as a mentor to generations of students and postdocs, his generosity as a colleague, his leadership of great scientific institutions, and his deep involvement in international efforts to define ethical boundaries for biological advances fill out an extraordinary intellectual life.”

Baltimore was born in New York City in 1938. His father worked in the garment industry, and his mother later became a psychologist at the New School and Sarah Lawrence. Young David was academically precocious and decided he wanted to be a scientist after spending a high school summer learning about mouse genetics at the Jackson Laboratory in Maine. He graduated from Swarthmore College and earned his PhD in biology from Rockefeller University in 1964 with a thesis on the study of viruses in animal cells. He joined the Salk Institute in San Diego, married Huang, and moved to MIT in 1982, founding the Whitehead Institute.

Baltimore initially studied viruses like polio and mengovirus that make RNA copies of the RNA genomes to replicate, but later turned his attention to retroviruses, which have enzymes that make DNA copies of viral RNA. He made a major breakthrough when he proved the existence of that viral enzyme, now known as reverse transcriptase. Previously scientists had thought that the flow of information went from DNA to RNA to protein synthesis. Baltimore showed that process could be reversed, ultimately enabling researchers to use disabled retroviruses to insert genes into human DNA to correct genetic diseases.
