I observed, for example, that when I got an invitation to travel to give a talk in a different time zone, it mattered what time zone I was in when I got the invitation.  if well rested, in my home time zone, I would think, No big deal, about making a long trip and would likely accept.  However, if I was jet-lagged in a different time zone when the invitation came in, and in reach with the misery of travel, I would be far more likely to decline.

…Perhaps you’ve noticed when taking a long-haul flight that waiting for a connecting flight feels much worse if your layover is close to your final destination.

That is from the new and very stimulating The Opposite of Happiness: How Bad Feelings Make and Break Us, by George Loewenstein.  A very Smithian book I might add.  Reading this book, one also wonders if the researchers who do behavioral economics are more depressed than average?  (“I’ve met many depressive characters in my life, but one of the most reliably miserable people I’ve ever known is my friend and collaborator Matthew Rabin.”)

UK productivity rose at almost twice the pace previously estimated in the decade after the 2008 global financial crisis, according to new official figures that make Britain look much less of an international outlier.

Output per hour worked, the main measure of labour productivity, grew by an average of 1.3 per cent per year between 2009 and 2019, the Office for National Statistics said on Thursday. The ONS had previously estimated average annual growth of 0.7 per cent over the period.

The figure is based on a new “component-based” methodology that has already been adopted by many other national statistics institutes. It draws on a range of data sources to improve the ONS’s count of both the number of workers contributing to UK output and the number of hours worked.

Here is more from Delphine Strauss at the FT.

…this month, Singapore launched a scheme promising actual cash to citizens as a reward for logging reading time on a government website.

It’s unlikely to make you megabucks – you have to rack up 50 reading sessions of at least 15 minutes to earn one Singapore dollar (£0.59), with only one logged session allowed per day. But behavioural scientists and psychologists told the Guardian such a scheme could still help boost a habit in precipitous decline…

We all know reading has long-term benefits, but a key element of the Singapore scheme hinges on introducing a short-term reward for the activity, mimicking the immediate dopamine hit of scrolling. In fact, the “gamified” element may be “smarter” than the financial reward offered, says Patrick Taylor, director of education at the Behavioural Insights Team (which originated in David Cameron’s Cabinet Office, also known as the “nudge unit”). “Having a manageable 15-minute daily goal, built around existing routines like commuting or bedtime, with streaks and tracking to keep progress visible” are the aspects that could make the scheme a success, he says.

]]> Scott Aaranson, theoretical computer scientist writes:

My position on AI is merely the conservative, skeptical position of 2006, updated with intellectual honesty for the reality of late 2026. And that position, if you need me to spell it out, is as follows:

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

It seems to me that the Singularity has already started; it’s just wildly unevenly distributed. Yes, I still unload the dishwasher and clip my toenails. On the other hand, in whatever years I have left, I don’t expect that I’ll ever again prove a theorem because I’m actually needed to prove it. If I do, it will only be for my or others’ enjoyment or edification.

The test is this: if we took the news of these past few weeks and sent it back in time twenty years, would I agree that it looked like the beginning of an AI Singularity? The intellectually honest answer is: yes, absolutely. But then that’s all we need. No backsies.

I feel like it would be healthy for everyone to stop grinding their ideological axes, their sentiments about Dario Amodei or Sam Altman, for long enough simply to acknowledge that the wonders and terrors are here. They couldn’t be here more clearly if the sky had turned reddish-orange like in the Matrix movies.

It’s here clearly enough that, when I put my kids to sleep at night, I now feel it in the pit of my stomach: what sort of future can they possibly have? What could they learn today that could possibly be relevant to that future? (Yesterday, my 13-year-old daughter joked unprompted that, if she wants to become a mathematician, it now looks like she has maybe two more weeks.) Certainly when my grad students want to discuss what sort of careers might await them on graduation, I no longer have any clue what to tell them.

…For anyone who says AI doom sounds like an apocalyptic religion, that the rationalists/Singulatarians seem like a Bay Area cult, that Eliezer Yudkowsky gives off the vibes of a messianic prophet: yes, yes, and yes. But crucially, today you’re no longer being asked to believe in arguments and extrapolations, but only in the front-page news. Accepting the reality of the coming machine god after it’s solved Navier-Stokes and dozens of other longstanding open math problems (while dramatically ramping up in capability every month), is sort of like accepting Jesus after he’s returned to earth on the gleaming cloud. It’s the epistemic bare minimum.

Yes, there’s still enormous uncertainty about what the rest of our lives will look like, but as far as I can tell, there’s no longer any real uncertainty that it’ll all mostly revolve around AI, and the extent to which we succeed or fail at directing its power toward human flourishing.

By any accounting that doesn’t stack the deck, Eliezer Yudkowsky was right about what the greatest challenge facing civilization in our lifetimes was going to be, and you and I were wrong about it. Why I was wrong is a question I’ll ask myself every day in whatever time remains. But, you know, at least I updated once the prophesied wonders and terrors actually started arriving! If you haven’t done likewise, why haven’t you?

Using a panel of 81 countries across six World Values Survey waves (1990–2022), we examine whether growth in internet diffusion is associated with religious decline. We construct a six-item composite religiosity index, align annual macro series to wave periods, and estimate country fixed-effects models with one-wave lags and a broad set of modernization, demographic, welfare-state, and cultural controls. We also estimate models separately for individual dimensions of religiosity. Across specifications, lagged internet penetration is negatively associated with religiosity within countries over time. These results remain robust under period dummies and in models estimated without lags, although reverse-ordering tests indicate that prior religiosity can also predict later internet use. Associations are strongest for denominational belonging and self-identification as a religious person. Overall, internet diffusion emerges as a robust macro-level correlate of within-country religious decline.

Here we introduce Paper2Agent, an automated framework that converts research papers into artificial intelligence (AI) agents. Paper2Agent transforms research output from passive artefacts into active systems that accelerate use and discovery. Conventional research papers require readers to understand and adapt the paper’s code, data and methods to their work, creating barriers to dissemination and reuse. Paper2Agent addresses this challenge by converting a paper into an AI agent that functions as a virtual corresponding author, exposing its manuscript, supplementary materials, datasets, code and workflows as active, agent-native knowledge rather than static text. It analyses the paper and codebase using multiple agents to construct a model context protocol (MCP) server, then generates and runs tests to refine and increase robustness of the MCP. These paper MCPs can be connected to a chat agent (such as Claude Code) to carry out complex scientific queries through natural language while invoking tools and workflows from the paper. We demonstrate Paper2Agent’s effectiveness through case studies. Paper2Agent created an agent that leveraged AlphaGenome1 to interpret genomic variants and agents based on Scanpy2 and TISSUE (transcript imputation with spatial single-cell uncertainty estimation)3 to conduct single-cell and spatial transcriptomics analyses. We validate that these agents reproduce the results of the original papers and carry out novel user queries. Paper2Agent created multiple agents that collaborate to prioritize a causal gene for psoriasis. By turning static papers into interactive AI agents, Paper2Agent introduces a paradigm for knowledge dissemination and a collaborative ecosystem of AI co-scientists.

As I have been saying for a while now, there is much more of this coming down the pike.  Via Charles Klingman.

And this leads to the most interesting part of this story: how the highlanders were so isolated for so long.

I want to acknowledge that the highlanders were not completely, hermetically sealed off from the outside world – it’s just that knowledge of outside world never actually made it to them or vice versa.

Over time, a few goods did make their way up to the highlands: pigs, about 3,000 years ago; the sweet potato, which is South American and arrived about 300 to 400 years ago; and tobacco, also American, which came the same way.

The journey the sweet potato and tobacco took to get there is a good example of how this all worked without transmitting further information. The Spanish and Portuguese brought both plants to the spice islands (in what is now Indonesia), just off the western tip of New Guinea, in the 1500s. The sultanates had been trading with the western tip of the coastal region of New Guinea for centuries. So the plants crossed over and started moving east along the coast and up into the interior. Beyond that point, there were no merchants. But when a woman married into the next clan over, she took cuttings from her family’s garden with her. Each new family then planted the same, saw that it worked, and passed it on. At that pace the sweet potato crossed the highlands in a century or two, with nobody knowing where it came from beyond the tribe beside them.

And what fascinates me is that even with the highlands as sealed off as they were, such significant goods still got in. Sweet potatoes allowed a population explosion in the highlands: they give far more calories per acre, and pigs can live off them. So in a 10,000 year sealed off universe, after the invention of agriculture, the biggest change to highland life happened in the last 500 years, which I guess isn’t a coincidence, as the sweet potato got there through the same structural forces that later brought the Australians.

Here is much more from Daniel Frank, fascinating throughout.

If COVID began with a laboratory leak—plausible, though unproven—then a research accident has already killed millions. Whatever its origin, COVID demonstrated the scale of the potential damage. AI surely increases pandemic risks. If you have ever used AI to fix your washing machine, you understand the difference between reading a manual and having a tutor by your side helping to troubleshoot each problem. The same distinction matters for biological research at the laboratory bench.

Anthropic’s threat report documents five cases of researchers using its models in ways that “could support biological weapons development.” These included military-linked virus research and plans for work on pathogens with enhanced pandemic potential. Did the researchers intend to build weapons? We don’t know. But some users circumvented access controls and concealed sensitive aspects of their research.

Some safeguards appear to have worked but we don’t know the base rate. And what will happen with open-weight models and AIs not under the control of a large corporation? The safeguards also burden legitimate researchers. We should accept that AI will magnify the power of small groups, ill-intentioned or not.

Of course, AI can accelerate vaccines and treatments too. But faster science does not automatically mean faster defense. Turning discoveries into deployed vaccines and treatments requires institutions that can act quickly. We should not assume those institutions will keep pace with the technology.

That makes the recommendations in my 2025 paper, Pandemic Preparation Without Romance, more urgent (surprise!): wastewater surveillance; prediction markets; pre-developed vaccine libraries; human challenge trials planned in advance; a Pandemic Trust Fund; and temporary Operation Warp Speed–style public–private partnerships.

My paper argues that pandemic policy should not depend on unusually farsighted or wise politicians. Public tripwires and banked resources are what you build when you don’t trust the authorities to move quickly in a crisis hence the value of ideas like wastewater surveillance, vaccine libraries, and ready challenge-trial protocols. None of these technologies is highly expensive nor do they require much in the way of continued investment and attention, hence pandemic preparation without romance.

Annie Lowrey’s new book, The Time Tax, argues that the most regressive levy in American life is the hours each of us must spend on hold, in waiting rooms, and filling out forms a competent state would have pre-filled — roughly fifty a year on average, and far more if you’re poor. Tyler spends much of this conversation pressing the opposite case, asking whether that bureaucracy is quietly serving a useful purpose by rationing knee surgeries that don’t work, deterring fraud, or screening for immigrants with gumption.

So Tyler and Annie hash it out over an hour, covering why TANF and other welfare programs are the worst offenders, the political economy of submerged benefits like the child tax credit, whether the postal service should be zeroed out over ten years the way Denmark did, whether the government should be nudging people out of rural areas, lessons from the COVID unemployment fraud, areas where the time tax is flat instead of regressive, which private sector time taxes are most onerous, whether AI agents will pay these taxes for us within five years, the logic of easy benefits plus randomized harsh audits, the case for less federalism, whether voting should be easier or harder, how the UBI studies changed her priors, where you can find the best moss in the world, her favorite example of Brutalist architecture, tattoos as permanent ephemera, Christianity’s role in liberalism and the post-Christian right, how reporting beats tourism, the time tax of friendship, what she’ll learn next, and more.

Excerpt:

LOWREY: The postal service and Social Security’s retirement programs. Those are both pretty good. Social Security also has other programs, SSI, which is mostly used by very, very low-income seniors with disabilities or who are blind. Disability insurance is run by the Social Security Administration. The retirement program, it’s less than 1 percent overhead. It’s great. It does all the work for you.

COWEN: Isn’t our whole postal service a time tax in the aggregate? Denmark, just this year, abolished its postal service. They don’t have any. Now, I understand we’re not in a position to do exactly the same, but shouldn’t we be moving away from postal service, basically zeroing it out over the next 10 years?

LOWREY: Did they make it so that it’s all digital? Did they digitize things?

COWEN: Well, I don’t know who the “they” is. Direct mail there has gone away.

LOWREY: Oh, yes, that’s interesting. I don’t know. I think in a high inequality country such as ours, where you still have a lot of people who don’t have smartphones and don’t have computers, that’s why I would be very concerned about the postal service going away.

COWEN: That’s why we need 10 years. You want to tax people, tax in the broad sense of the term, living in rural areas, if only because it’s much harder to have government help them, right?

LOWREY: Yes.

COWEN: If rural areas don’t get mail anymore, maybe that’s a good thing.

LOWREY: I don’t think that that’s a good thing for the people in the rural areas, though. There’s always going to be people in rural areas. As a general point, do you want the government to be encouraging people to not live in rural areas?

COWEN: Absolutely, that’s me. Welcome to the show.

LOWREY: That’s feels very nanny state-ish of you, Tyler.

COWEN: I don’t want to subsidize rural areas, and we do it in so many ways, including with our farm programs.

LOWREY: We do. We really, really absolutely do.

COWEN: It gets harder to help people with government. There’s a lot more market power in rural areas, like how many supermarkets are there, how many hospitals, probably just one, if that. Let’s get everyone into the suburbs, or heaven forbid, the cities.

LOWREY: I can’t imagine a less popular policy than that.

COWEN: Absolutely.

Interesting throughout, and full of good spirit.  Again, here is Annie’s very good book The Time Tax: How Government Wastes Our Time — And How to Fix It.

]]> I agree with Alex that the standard model of regulatory capture does not apply here, but I think he neglects the best model we have.  From my recent Free Press piece:

Recently I have been reading my review copy of Kevin Roose’s excellent forthcoming book The AGI Chronicles: The Inside Story of the Race to Create an Artificial Superintelligence. A major theme of the book—I would say the major theme—is how strong and competitive the rivalries have been between Dario, Altman, and Musk. Each believes that the others cannot be trusted to gain super-powerful AI capabilities.

Thus, when you observe these individuals and their companies jockeying for position and preeminence, it is too cynical to think it is just about the money (each of them already has plenty). The actions of each are rooted in the sincere belief that their own company would best serve the world by winning the race toward very powerful AI.

So when these CEOs plead altruism, you should actually believe them, even though obvious selfish motives also happen to align with their plans. One can reasonably argue about who ought to win the race, but I favor the outcome where all of them, including Meta and Google, roughly tie for first place, and the market remains highly competitive.

So they are selfish in a sense, but along the metric of power, where they perceive (correctly or not) “selfish and altruistic” to be quite closely correlated.  Note I am using the word “power” in a general capabilities sense, you do not have to believe they intend evil coercive exercise in this context.  Furthermore, it is not mainly about “capturing the regulator,” but rather winning in the market and then having an immense ability to achieve ends before the others do.  So yes they are sincerely worried about a host of safety issues, but they are all the more sincerely worried about not being the ones to win the race. To the extent we wish to cite those CEOs as authorities, “who gets it is the most important thing of all” would be the takeaway lesson.

Do note that for all the talk of pause, the race to invest in compute is continuing apace and even intensifying.  That is the real variable to watch.  If a theory does not explain observed behavior toward compute, which of course costs real dollars, the theory is failing to explain what is going on.

Standard competition!  I do not flip out about this.  But obviously there are some world views where you might view these (and other) actors as evil, and furthermore think they can act without much constraint, and so on.  Those are not my world views.  I see a lot of competition and a lot of ego, and then I think of Adam Smith.  Standard stuff, just at much higher stakes than usual.
