After 50 years of little growth, new breakthroughs in science and medicine could mean the start of a whole new era of innovation! Economist @tylercowen paints a new picture of the future — and a road map to get us there.
— TED Talks (@TEDTalks) June 3, 2021
I think this episode came off as “weird and testy,” as I described it to one friend, but I like weird and testy! Here is the audio, video, and transcript. Here is one excerpt:
COWEN: How do you think the many-worlds interpretation of quantum mechanics relates to the view that, just in terms of space, the size of our current universe is infinite, and therefore everything possible is happening in it?
DEUTSCH: It complicates the discussion of probability, but there’s no overlap between that notion of infinity and the Everettian notion of infinity, if we are infinite there, because the differentiation (as I prefer to call what used to be called splitting) — when I perform an experiment which can go one of two ways, the influence of that spreads out. First, I see it. I may write it down; I may write a scientific paper. When I write a paper about it and report the results, that will cause the journal to split or to differentiate into two journals, and so on. This influence cannot spread out faster than the speed of light.
So an Everett universe is really a misnomer because what we see in real life is an Everett bubble within the universe. Everything outside the bubble is as it was; it’s undifferentiated, or, to be exact, it’s exactly as differentiated as it was before. Then, as the bubble spreads out, the universe becomes or the multiverse becomes more differentiated, but the bubble is always finite.
COWEN: How do your views relate to the philosophical modal realism of David Lewis?
DEUTSCH: There are interesting parallels. As a physicist, I’m interested in what the laws of physics tell us is so, rather than in philosophical reasoning about things, unless they impinge on a problem that I have. So yes, I’m interested in, for example, the continuity of the self — whether, if there’s another version of me a very large number of light-years away in an infinite universe, and it’s identical, is that really me? Are there two of me, one of me? I don’t entirely know the answer to that. It’s why I don’t entirely know the answer to whether I would go in a Star Trek transporter.
The modal realism certainly involves a lot of things that I don’t think exist — at least, not physically. I’m open to the idea that nonphysical things do exist: like the natural numbers, I think, exist. There’s a difference between the second even prime, which doesn’t exist, and the infinite number of prime numbers, which I think do exist. I think that there is more than one mode of existence, but the theory that all modes of existence are equally real — I see no point in that. The overlap between Everett and David Lewis is, I think, more coincidental than illuminating.
COWEN: If the universe is infinite and if David Lewis is correct, should I feel closer to the David Lewis copies of me? The copies or near copies of me in this universe? Or the near copies of me in the multiverse? It seems very crowded all of a sudden. Something whose purpose was to be economical doesn’t feel that way to me by the end of the metaphysics.
DEUTSCH: It doesn’t feel like that to you. . . . Well, as Wittgenstein is supposed to have said (I don’t know whether he really did), if it were true, what would it feel like? It would feel just like this.
Much more at the link. And:
COWEN: Are we living in a simulation?
DEUTSCH: No, because living in a simulation is precisely a case of there being a barrier beyond which we cannot understand. If we’re living in a simulation that’s running on some computer, we can’t tell whether that computer is made of silicon or iron, or whether it obeys the same laws of computation, like Turing computability and quantum computability and so on, as ours. We can’t know anything about the physics there.
Well, we can know that it is at least a superset of our physics, but that’s not saying very much; it’s not telling us very much. It’s a typical example of a theory that can be rejected out of hand for the same reason that the supernatural ones — if somebody says, “Zeus did it,” then I’m going to say, “How should I respond? If I take that on board, how should I respond to the next person that comes along and tells me that Odin did it?”
COWEN: But it seems you’re rejecting an empirical claim on methodological grounds, and I get very suspicious. Philosophers typically reject transcendental arguments like, “Oh, we must be able to perceive reality, because if we couldn’t, how could we know that we couldn’t perceive reality?” It doesn’t prove you can perceive reality, right?
COWEN: A few very practical questions to close. Given the way British elections seem to have been running, that the Tories win every time, does that mean the error-correction mechanism of the British system of government now is weaker?
DEUTSCH: No. Unfortunately, the — so, as you probably know, I favor the first-past-the-post system in the purest possible form, as it is implemented in Britain. I think that is the most error-correcting possible electoral system, although I must add that the electoral system is only a tiny facet of the institutions of criticism and consent. In general, it’s just a tiny thing, but it is the best one.
It’s not perfect. It has some of the defects of, for example, proportional representation. Proportional representation has the defect that it causes coalitions all the time. Coalitions are bad.
COWEN: You have a delegated monitor with the coalition, right? With a coalition, say in the Netherlands (which is richer than the United Kingdom), you typically have coalition governments. Some parties in the coalition are delegated monitors of the other parties. Parties are better informed than voters. Isn’t that a better Popperian mechanism for error correction?
I also tried to sum up what I think he is all about, and he reacted with scorn. That was an excellent part of the conversation. And here is a good Twitter thread from Michael Nielsen about the Conversation.
The Ford F-150 truck has been America’s best selling vehicle for forty years! (Bubble test: Do you own one or know someone who does?) The new version, the F-150 Lightning, goes into production in 2022 and it’s electric. Even today there is still the whiff of “liberal America” around electric vehicles but what’s impressive about the Lightning isn’t that it’s electric, it’s that it’s a better truck. The Lightning, for example, can power a home and work appliances from its 11 outlets including a 240 volt outlet! Look at this brilliant ad campaign:
Security and peace of mind are invaluable during severe weather and unpredictable events. That’s why Ford helps ensure you never have to worry about being left in the dark…
Security, peace of mind, don’t be left alone in the dark…all great conservative selling points. Note the truck in the picture is powering the house and the chain saw. The husband and wife, their home and their truck, project independence, success and confidence–a power couple–even with a nod to diversity.
The Lightning is also fast with 0-60mph times in line with those of a Porsche 911 circa 2005, it has more carrying capacity (thanks to the smaller electric motors) than a similar gas vehicle, and it can tow a respectable maximum of 10,000 pounds with all the options.
The Lightning might succeed or it might fail but it won’t fail on politics, this is a vehicle a red-blooded, meat-eating skeptic of global warming could love.
Here is Ross Douthat at the NYT:
…there’s a pretty big difference between a world where the Chinese regime can say, We weren’t responsible for Covid but we crushed the virus and the West did not, because we’re strong and they’re decadent, and a world where this was basically their Chernobyl except their incompetence and cover-up sickened not just one of their own cities but also the entire globe.
The latter scenario would also open a debate about how the United States should try to enforce international scientific research safeguards, or how we should operate in a world where they can’t be reasonably enforced.
I agree, and would add one point about why this matters so much. “Our wet market was low quality and poorly governed” is a story consistent with the Chinese elites not being entirely at fault. Wet markets, after all, are a kind of atavism, and China knows the country is going to evolve away from them over time. They represent the old order. You can think of the CCP as both building infrastructure and moving the country’s food markets into modernity (that’s infrastructure too, isn’t it?), albeit with lags. “We waited too long to get rid of the wet markets” is bad, but if anything suggests the CCP should have done all the more to revolutionize and modernize China. In contrast, the story of “our government-run research labs are low quality and poorly governed”…that seems to place the blame entirely on the shoulders of the CCP and also on its technocratic, modernizing tendencies. Under that account, the CCP spread something that “the earlier China” did not, and that strikes strongly at the heart of CCP legitimacy. Keep in mind how much the Chinese apply a historical perspective to everything.
A number of you have asked me what I think of the lab leak hypothesis. A few months ago I placed the chance of it at 20-30%, as a number of private correspondents can attest. Currently I am up to 50-60%.
That is the topic of my latest Bloomberg column, here is one excerpt:
Here’s the dirty little secret that few of my fellow economics professors will admit: As those “perfect” research papers have grown longer, they have also become less relevant. Fewer people — including academics — read them carefully or are influenced by them when it comes to policy.
Actual views on politics are more influenced by debates on social media, especially on such hot topics such as the minimum wage or monetary and fiscal policy. The growing role of Twitter doesn’t have to be a bad thing. Social media is egalitarian, spurs spirited debate and enables research cooperation across great distances.
Still, an earlier culture of “debate through books” has been replaced by a new culture of “debate through tweets.” This is not necessarily progress.
To use a bit of economic terminology, economists haven’t fully internalized the lessons of the Laffer Curve. By demanding so much rigor in academic research, they’ve created an environment in which most of the economics people actually see is less rigorous.
There is also a political effect. Twitter is a relatively left-wing social medium, and so the tenor of popular economic discourse has moved to the left.
Recommended, and it is one of those pieces where the reaction to the piece itself confirms the thesis of the piece…

That is the theme of my latest Bloomberg column, here is one excerpt:
Now, for the first time in my life, I feel like I am living in a science fiction serial.
The break point was China’s landing of an exploratory vehicle on Mars. It’s not just the mere fact of it, as China was one of the world’s poorest countries until relatively recently. It’s that the vehicle contains a remarkable assemblage of software and artificial intelligence devices, not to mention lasers and ground-penetrating radar.
There is a series of science fiction novels about China in which it colonizes Mars. Published between 1988 and 1999, David Wingrove’s Chung Kuo series is set 200 years in the future. It describes a corrupt and repressive China that rules the world and enforces rigid racial hierarchies.
It is striking to read the review of the book published in the New York Times in 1990. It notes that in the book “the Chinese somehow regained their sense of purpose in the latter half of the 21st century” — which hardly sounds like science fiction, the only question at this point being why it might have taken them so long. The book is judged unrealistic and objectionable because its “vision of a Chinese-dominated future seems arbitrary, ungrounded in historical process.” The Chung Kuo books don’t reflect my predictions either, but it does seem that reality has exceeded the vision of at least one book critic.
I also consider Asimov, Dogecoin, and Stephenson at the link.
What if they turn out to be “a thing”? Here is one excerpt, to be clear this is not the only view or possibility he is putting forward:
One immediate effect, I suspect, would be a collapse in public trust. Decades of U.F.O. reports and conspiracies would take on a different cast. Governments would be seen as having withheld a profound truth from the public, whether or not they actually did. We already live in an age of conspiracy theories. Now the guardrails would truly shatter, because if U.F.O.s were real, despite decades of dismissals, who would remain trusted to say anything else was false? Certainly not the academics who’d laughed them off as nonsense, or the governments who would now be seen as liars.
One lesson of the pandemic is that humanity’s desire for normalcy is an underrated force, and there is no single mistake as common to political analysis as the constant belief that this or that event will finally change everything. If so many can deny or downplay a disease that’s killed millions, dismissing some unusual debris would be trivial. “An awful lot of people would basically shrug and it’d be in the news for three days,” Adrian Tchaikovsky, the science fiction writer, told me. “You can’t just say, ‘still no understanding of alien thing!’ every day. An awful lot of people would be very keen on continuing with their lives and routines no matter what.”
Excellent column, do read the whole thing (NYT).
From my Bloomberg column, here is one of them:
A possible Chinese move against Taiwan has received a lot of attention, but a Russian union with Belarus could be a greater danger. Belarus might even agree to such a proposition, so it would be hard for NATO or the U.S. to decry it as a coercive invasion. Yet such a Russian expansion could upend political stability in Europe.
If Russia and Belarus became a single political unit, there would be only a thin band of land, called the Suwalki Gap, connecting the Baltics to the rest of the European Union. Unfortunately, that same piece of territory would stand in the way of the new, larger Russia connecting with the now-cut off Russian region of Kaliningrad. Over the long term, could the Baltics maintain their independence? If not, the European Union would show it is entirely a toothless entity, unable to guarantee the sovereignty of its members.
Even if there were no formal political union between Russia and Belarus, the territorial continuity and integrity of the EU could soon be up for grabs. The EU has more at stake in an independent Belarus than it likes to admit.
You will find three more undervalued possible news stories at the link.
My jaw just about hit the floor when I read this paper.
It is commonly believed that psychic ability, like many mental and physical traits, runs in families. This suggests the presence of a genetic component. If such a component were found, it would constitute a biological marker of psychic ability and inform environmental or pharmacologic means of enhancing or suppressing this ability.
On the one hand, almost every human trait has some genetic component. On the other hand, shouldn’t you demonstrate that a trait exists before searching for its genetic correlates? The combination of science and nonsense in this paper–seemingly without irony–is disconcerting, like discovering that Newton spent a huge amount of his time trying to discern hidden codes in the Bible.
On finding psychics and matched case-controls, “individuals with indications of psychotic or delusional tendencies were excluded from further consideration.” Ok, then.
Oh, in case you are wondering:
…none of the protein-coding sequences (i.e., exons) showed any variation that discriminated between cases and controls. However, a difference was observed in the intron (i.e., non-protein-coding region) adjacent to an exon in the TNRC18 gene (Trinucleotide Repeat-Containing Gene 18 Protein) on chromosome 7. This variation, an alteration of GG to GA, was found in 7 of 9 controls and was absent from all psychic cases.
The most conservative interpretation of these results is that they result from random population sampling. However, when the results are considered in relation to other lines of evidence, the results are more provocative. Further research is justified to replicate and extend these findings.
Hat tip: Jonatan Pallesen.
Primarily as an exercise, I thought about that question for a while, and here is part of my answer in a Bloomberg column:
If you know you are being watched, what exactly do you wish to buy more of? I would bet on defense stocks to rise, whether or not there is much we can do to defend ourselves against this alien presence.
Of course investors could not be sure that these alien drone probes will merely observe us forever. They might be observing with the purpose of rendering judgment. If they are offended by our militaristic tendencies, the quality of our TV shows and our inability to adopt the cosmopolitan values of “Star Trek” over the next 30 years, maybe they will zap us into oblivion. But that kind of systematic risk is hard to insure against. After such an act of obliteration, neither gold nor Bitcoin will do you any good.
My main prediction is that alien UFOs will be bullish for the dollar. The U.S. government seems most closely connected to the UFO phenomenon, for whatever reason. (Maybe its pilots fly more sallies and record better data?) In any case, if alien UFOs become more likely, an informational advantage would accrue to the federal government. And the dollar already has a tradition as a safe haven currency…
Most of us would get used to the idea of alien presence without quite believing in it. As The New Yorker makes clear, many Americans believed in alien-origin UFOs after World War II, as did many American policymakers. It might have spurred greater interest in the space program and science fiction, but it didn’t affect most aspects of American life, nor did it seem to drive markets.
Never underestimate the capacity of markets, like humans, to adapt. Just as many of the strangest parts of our lives can come to seem normal, so Wall Street can find a way to do business with just about anybody — aliens included.
I do full, literally mean everything stated in the column. But the piece also has (at least) two esoteric meanings — can you guess what they are?
Solo authorship represented 80 percent of economics papers in 1960 and 65 percent in 1990, but then solo-authorship fell out of the majority in 2005 and represents only 26 percent of economics papers today (as measured by the right-hand axis). To put it another way, in 1950, there were 1.2 authors per economics paper. Average team size reached 2.0 for the first time in 2010. By 2018, team size averaged 2.7 (as shown on the left-hand axis). The jump in average team size in economics papers over the last ten years is greater than the jump over the prior half-century.
Here is more from Benjamin F. Jones. For higher impact papers, the trend is even more striking.
The carbonaceous winners are plants, which make up about 80 percent of all biomass on Earth. Bacteria comes in second at 13 percent and fungus is third at just 2 percent.
Of the 550 gigatons of biomass carbon on Earth, animals make up about 2 gigatons, with insects comprising half of that and fish taking up another 0.7 gigatons. Everything else, including mammals, birds, nematodes and mollusks are roughly 0.3 gigatons, with humans weighing in at 0.06 gigatons. The research appears in The Proceedings of the National Academy of Sciences.
“The fact that the biomass of fungi exceeds that of all animals’ sort of puts us in our place,” Harvard evolutionary biologist James Hanken, who was not involved with the study, tells Borenstein.
…the biomass of domesticated poultry (≈0.005 Gt C, dominated by chickens) is about threefold higher than that of wild birds…
…the total plant biomass (and, by proxy, the total biomass on Earth) has declined approximately twofold relative to its value before the start of human civilization. The total biomass of crops cultivated by humans is estimated at ≈10 Gt C, which accounts for only ≈2% of the extant total plant biomass…
In terms of biomass, mollusks are a bigger deal than you might think.
Thousands of people at a mass nightclub rave in the U.K. this week will be a key test of whether live events halted during the pandemic can reopen at full capacity as planned from the end of June.
The two-day event in Liverpool, northwest England, is part of a national research program which so far appears to show people are happy to be tested for coronavirus to secure entry to large-scale events.
There are also no early signs that live events are spreading the disease, according to government scientist Paul Monks, and the program is expected to move to its second phase next month — with live events held at a “full range” of indoor and outdoor venues with “different scales” of capacity.

The Biden administration today began to flesh out a proposal for a new agency—modeled on the military’s Defense Advanced Research Projects Agency (DARPA)—that would seek to speed the development of medical treatments by funding risky, innovative projects. The agency, dubbed ARPA-Health (ARPA-H), would be housed at the National Institutes of Health and have a 2022 budget of $6.5 billion, according to a White House spending request released today.
Few other details about ARPA-H have been released, except that it would initially focus on cancer and diseases “such as diabetes and Alzheimer’s.”
…Under the DARPA model, projects would not be vetted by peer reviewers, but instead, funding decisions would be made by program managers. And instead of multiyear grants, the agency would disburse awards as milestone-driven payments; program managers could also cancel projects that they decide aren’t panning out.
