I'll add that Section 4 of the 14th amendment of the US Constitution makes it unconstitutional for the US government to default on its debt. However, the US government is currently printing money at prodigious rates; the possibility that the dollar may not hold its value is a realistic concern. Naturally this would impact the value of dollar-denominated bonds.

Well, we can say that 27/30 (90%) patients improved. With a very high level of confidence, we can say that this disease is less fatal than Ebola (which would have killed 26 or so).

I've definitely seen this in the academic literature. And it's extra annoying if the study used a small sample; the p-values are going to be large simply because the study didn't collect much evidence.

OTOH, chemotherapy isn't a very good example because there are other factors at work:

  • Chemotherapy has serious side effects. There are good reasons to be cautious in using extra.
  • There are also not-as-good reasons to avoid using extra chemotherapy. Medical care is highly regulated and liability-prone (to varying extents in various areas). In the US, insurers are notoriously reluctant to pay for any treatment they consider unnecessary. Departing from standard practice is likely to be expensive.

I'll add that this is a cycle; Stage 5 is Stage 1. People operating in Stage 4 are paying very little attention to objective reality. Accordingly, their objective situation is usually deteriorating; competitors operating at lower levels gradually eat their lunch without them really noticing. The cycle restarts when objective conditions deteriorate to the point that they can no longer be ignored and the complicated games of social signaling are abandoned. To extend Strawperson's comment:

Level 1: "There's a lion across the river." = There's a lion across the river.
Level 2: "There's a lion across the river." = I don't want to go (or have other people go) across the river.
Level 3: "There's a lion across the river." = I'm with the popular kids who are too cool to go across the river.
Level 4: "There's a lion across the river." = A firm stance against trans-river expansionism focus grouped well with undecided voters in my constituency.

Level 5/Level 1: "There's a lion right here" = There's a lion right here (We really should have been paying more attention to the actual lion and focus groups no longer seem important).

I was curious about how much we could rely on that safety, and it turns out there are threshold limit values (see the sixth slide) for UV-C. Between 200 and 220 nm the TLVs are .02 to .08 J/cm^2 (200 to 800 J/m^2), according to the American Conference of Governmental Industrial Hygienists. At 5W/m^2 (your suggested irradiation) that gives you 40 to 160 seconds of reasonably safe human exposure.

True, but there are some anti-assembly laws being passed and enforced anyway. They're clearly unconstitutional and, if left in place very long, will be struck down. Emergency actions are often more political than legal; if you do something illegal but the people who could check and balance you decide not to (hopefully because your actions make sense), you can get away with a lot.

There are limits; the perceived benefit of the action has to overcome the insult to legal propriety in the relevant minds. Banning meetings for a few weeks will probably fly, especially if the internet can substitute.

It's the "someone is in fact harmed" that is the tricky part in this case. If somebody who was previously asymptomatic got coronavirus a week after Bob walked past them, how do you propose to determine whether they got it from Bob? If you're proposing a criminal penalty in the U.S., then you will need to prove this beyond a reasonable doubt. Probabilities of less than 99% won't do, and there may be a few jurors who think 99.9999% still gives a reasonable doubt (the jury system has been described as "trial by people you would not normally consider your peers").

Quarantine actually is the same thing as imprisonment, because you can't leave. You are deprived of liberty. The justification is different, but a justification and $3 would get you a coffee if Starbucks weren't closed. The US Constitution was written with the understanding that politicians are prone to lying when convenient.

Negligence can be an element of a crime. You need a guilty act and some level of guilty mind (purpose, knowledge, recklessness, or negligence, in declining order of culpability). Walking around isn't a guilty act. Homicide is a guilty act, but you'd have to prove beyond a reasonable doubt that the defendant's actions caused the death. It will be very hard to prove that the victim's infection came from the defendant and not from any of the large number of other infectious people that are the defining feature of a pandemic.

Endangerment might work, depending on circumstances and jurisdiction, but I would expect courts to be skeptical. Walking around isn't reckless or wanton, by conventional definitions.

Bob walks around most days. People die every day. Sure, Bob might have been unknowingly transmitting COVID, or any of a thousand other viruses. Bob was definitely, by the act of breathing, affecting the course of every hurricane for the rest of time. How do you assign culpability?

Legally, there are two reasons (in the US):

1) The Fifth Amendment: No person shall ... be deprived of life, liberty, or property, without due process of law. Quarantine looks very much like imprisonment, and the power to indefinitely imprison without due process is an extremely dangerous one.

2) Negligence is a tort**, not a crime, and torts have to prove damages by a preponderance of the evidence. You can't successfully sue Bob for giving you COVID unless you can prove it more likely than not that your COVID came from Bob. That's basically impossible.

** As it should be. People slack off very frequently, and if inconsequential slacking off was criminally punished then civilization would collapse.

1) 254 nm is the same part of the spectrum that the ozone layer protects us from, and also the absorption peak for DNA. IIRC non-aquatic life didn't take off until the ozone layer formed, probably for that reason. UV does bad things to DNA, and I wouldn't bet on dead skin providing adequate protection from large exposures. The DNA spectrum has another peak around 212 nm (although the dropoff at low energy may be from the limitations of the optics rather than from lower absorption by the molecule).

2) The absorption spectrum for melanin shows its strongest peak between 270 and 220 nm. I'd say it depends on whether the dropoff below 220 nm was due to the absorption characteristics of the molecule or was an artifact of the measurement (spectrometer, cuvette, solvent, etc.). I'm inclined to guess artifact; such a sharp dropoff toward higher energy doesn't make physical sense (unless I'm missing something).

Married sex is a sacrament, unmarried sex is a grave sin. (Married being a social state that is easy for two people to enter but hard for them to leave)

You realize that they didn't have birth control, right? Sex makes babies. Marriage provides the legal infrastructure for parents to raise kids; for example a married woman is likely to have a man around when she's too pregnant for agricultural labor. All known human societies have something like marriage (in considerable variations), and it's hardly surprising that they thought sex without marriage was a bad idea.

Conceiving children is important and good.

If our ancestors hadn't, we literally wouldn't exist. Also remember that sex and conception back then were one decision, not two separate decisions.

The details of 'sex' are explicitly left undefined.

Even squirrels figure out sex well enough to get by. They seem to have managed.

Overall, the Puritan attitude toward sex doesn't seem that irrational to me. There are fairly obvious reasons to adopt each of their policies, even if they were substantially ignorant of biology.

carefully chosen, but objectively false, beliefs

If you believe they're objectively false, you don't believe them. You believe that they're convenient, not that they're worth living for. If you ever get in a situation where everything has gone sideways and you really need an answer to what it's all about, as most people eventually do, they won't be enough.

Logical positivism asserted only statements verifiable through direct observation or logical proof should be considered meaningful. As a philosophical position, it's self-refuting (if it's true, it's meaningless). As a rule of thumb about which questions are likely to reward investigation, it works pretty well.

For example, "AI risk" is incredibly vague. "AI" is a large class of possible devices and there are many forms of "risk". If a problem can't be clearly stated then logical proof is not a useful approach, and direct observation only works on things that actually exist. So I'd say that "AI risk" is not likely to be a tractable question, although "the effect of algorithmic trading on US agricultural commodities markets" or "the effect of social media ranking algorithms on the 2020 US elections" probably are.

Personally my oxygen saturation always reads 91-93%. I'm 47 years old with no known lung problems who never smoked. People vary. I'm an unusually large man, so it may be a square-cube law effect or a finger-thickness effect. It may be some other confounder.

Under normal circumstances I would agree with the rest. In the very near future healthcare providers are expected to be absolutely swamped with coronavirus cases; apparently corpses have been piling up in Italy. I think my thresholds for action are stricter than yours because I'm trying to minimize strain on the system. But at 90% your plan is to go to the hospital and my plan is to call a doctor to find out if I should go to the hospital. That's not a huge difference.

I asked my dad, a doctor (internal medicine). My blood oxygenation is usually around 92-93%. It can vary for a number of reasons. Anything under 90% is considered hypoxia, but the high 80s can be "normal" in a long time smoker.

The hospital is likely to be very busy and not have time for mild cases. Blood oxygenation of 92% does not warrant their attention. I'd give my doctor (or the emergency room) a call at 90% oxygenation. At 85% it's definitely time to go to the hospital (unless they tell you otherwise). Below 80% brings a severe risk of organ failure, so that's a life threatening emergency.

Use common sense - if your doctor is telling you one thing an a random internet comment is telling you differently, believe the doctor. Also, if your readings are going down rapidly, call your doctor. Don't drive if you're significantly impaired.

Three points:

1) Any risk-benefit calculation should consider that COVID-19 appears to be only minimally harmful to the young and healthy. Deep UV can cause skin cancer at any age, which seems like a good reason to be careful here. Human DNA is not fundamentally different than virus DNA where UV light is concerned.

2) It might be safer in Africa or India where melanin protects the local populations from UV. Yes, that's what melanin is for.

3) Can we do the same thing, but safer, with a detergent mist?

I think mazes are related to the sorts of extreme principal-agent problems that are common in real life but AFAIK understudied by economics.

I don't know if maze-nature can be resisted, but the same factors that bring maze-nature also allow economies of scale and desirable types of complexity. All of the armies in WWII had considerable maze-nature, but that doesn't mean that fielding a smaller army would have worked better. Bigger armies usually win, despite the added levels of (mis)management. And the processes that turn natural materials into an iPhone are necessarily going to take millions of people, because phones are incredibly complex. Sometimes maze-nature may be an acceptable cost to pay, at least for a while.

A high maze level makes a fixation on object-level results impractical. Middle management has three defining characteristics:

  • It's remote from object-level interactions. It rarely deals with individual customers or particular bits of inventory. Its knowledge of the business process is largely abstract, and its concrete knowledge is often outdated (because it was accumulated before promotion). Object level outcomes (e.g. sales or new products) are not easily attributable to specific middle managers.
  • It is responsible to upper management, who is even more out of touch on the object level but demands "results" in the form of plausible data that can be spun to the markets as good results. Upper management also demands obedience to its narratives; when upper management tells the market your firm is going big into Fad X, then middle management needs to be seen to support Fad X. (Note 1)
  • Its staff have object-level information. They often have strong incentives to distort management's perspective of this information. When accurate information is available, it's often contrary to middle management's narrative. E.g. "Fad X? Yeah, we tried that twelve years ago. We could never monetize it."

If your organization gets big enough to need many layers of management (note 2), these effects will show up.

Note 1- A friend of mine at an Army lab told me that he was once asked by higher management how they would use nanotechnology in infrared sensors. My friend responded that, since infrared photons have micron-sized wavelengths, it didn't make sense to use nanotechnology. My friend was ordered to use nanotechnology anyway, and one of his experiments was eventually published (billed as an effort to use nanotechnology for this purpose). The experiment had actually been regarded as a failure because it had grown useless nanostructures instead of doing what it was supposed to do.

Note 2- It varies with activity, but generally a good manager can handle about six staff each. Since each six managers need an upper-level manager, you can use the base-6 logarithm of your worker count for a lower bound of the number of levels you need in your hierarchy. Note that this includes all workers in your process, even the work you contract out (contracting generally adds at least one level in practice).

Look for a system where the predictions of GR contradict, or at least interact with, the predictions of QM. If there is no such system, then the contradictions are more metaphysical than empirical.

I've wondered for a while if the gravitational anomalies ascribed to dark matter/energy could be the result of linear frame dragging through the quantum fields. The basic idea is:

1) QM says there's a lot of "zero-point energy" surrounding us in every direction related to the quantum fields.

2) This energy has no gravitational consequences because it's pulling equally in every direction.

3) Relativistic linear frame dragging might break that symmetry with gravitational consequences.

I don't have the background to go further with the idea, or even to tell whether it's blatantly stupid. It's a stray thought; if you can make something of it, feel free.

I think we should be clear to distinguish between person-level and population-level improvements. Individual-level improvement is relatively easy (for the young); just head to the gym or the library. Population-level improvement is much harder; eventually all of that self-improvement is lost to age. The improvements have to be continually replenished by training the young (unfortunately ignorance is a renewable resource). There's no intrinsic conflict between the belief that individuals can improve themselves through rational effort and the belief that society as a whole is in a steady state where self-improvement among the young roughly offsets declines due to age and infirmity.

In practice, it is often hard to tell the difference between "far ahead of the competition" and "off on a weird tangent". You could make the case that NASA is 50 years ahead of the competition in manned lunar space travel, and at the time being ahead of the Soviets was a huge part of the appeal. But over time manned space travel was all but abandoned because there didn't seem to be enough value in it. The USAF is in a similar position with stealth aircraft; competing countries never heavily invested in stealth and radar improvements have made it increasingly obsolete.

If you're three years ahead of intelligent, well-funded competition, they may be waiting to see if the game is worth the ante.

1) True, but by the time that roommate took the class he had had comparable math foundations to what I had had when I took the class. Considering the extra years, arguably rather more. (Upon further thought I realized that I had taken the class in 1988 at the age of 15)

2) That was first-semester calc, Purdue's Math 161 class (for me and the roommate). Intro calc. Over the next two years I took two more semesters of calc, one of differential equations, and one of matrix algebra. By the time I met my freshman roommate (he was a bit older than me) and he started the calc class, I'd had five semesters of college math (which was all I ever took b/c I don't enjoy math). Also, that roommate was a below-average college student, but there are people in the world with far less talent than he had.

3) Because time is the only thing you can't buy. Time in college can be bought, but not cheaply even then. I got through school with good grades and went on to grad school as planned; his plans didn't work out. Of course time marched on and I had failures of my own.

I agree that there's more to success than one particular kind of intelligence. Persistence, looks, money, luck, and other factors matter. But my roommate's calculus aptitude was a showstopper for his engineering ambitions, and I don't think his situation was terribly uncommon.

Personally, I learned a semester worth of calculus in three weeks for college credit at a summer program (the Purdue College Credit Program circa 1989, specifically) when I was 16. Out of 20ish students (pre-selected for academic achievement), about 15% (see note 1) aced it while still goofing around, roughly 60% got college credit but found the experience difficult, and some failed. Two years later, my freshman roommate (note 2) took the same Purdue course over 16 weeks and failed it. The question isn't "why don't some people understand calculus", but "why do some people learn it easily while others struggle, often failing".

Note 1: This wasn't a statistically robust sample. "About 15%" means "Chris, Bill, and I".

Note 2: That roommate wanted to be an engineer and was well aware that he could only achieve that goal by passing calculus. He was often working on his homework at 1:30 am, much to my annoyance. He worked harder on that course than I had, despite being 18 years old and having a (presumably) more mature brain.

The third thing is that it was the most valuable class I ever took, because it saved me from graduate school. 

I honestly wish I'd had that class. I think my physical chemistry classes were fundamentally similar, except that I failed them by continuing to grad school.

It seems obvious to me that society needs engineers and surgeons and scientists, and that those people actually do need a lot of education in the time-consuming, systematic-building-of-skills sense. It also seems obvious that society needs only 5% (wild guess) of the population to have that sort of education. Our society seems to have decided that it would be unconscionable to tell a child, however meatheaded, that they will never join that 5%. Instead we prefer to force all children to continue on that path until the age of 18, then encourage them to borrow to go further. Then most of them discover that they were never going to join the 5% and old people wonder why they're so angry.

Hmmm... in this model, humanities majors might realize the truth earlier, because even 18-year olds can't avoid the realization that an English degree isn't a ticket to wealth. They might get angry when they're still in college. Seems plausible.

I got my first 3 (B.S., M.S., Ph.D.) back in the 20th century and spent about 10 years in startups. And yes, the Ph.D. turned out to be a lot less marketable than expected, although I'm hardly the only one to have that problem. Fifteen years later I got another Master's and have been gainfully employed ever since. But I definitely have plenty of experience in learning things.

When I need to learn something, I read about it and work problems. It's not fundamentally different than getting anything else done. For me, that is. YMMV.

I do, but I find the world often requires me to stay productively on task even when I'd rather not. We old people used to call this "self-discipline".

I think this varies considerably by person. Personally, I have 4 university degrees and I've never really felt the need to pay attention to my moods in anything like this way. I generally got good enough results by waiting for the last minute, which triggered the "this needs doing now" mood that was sufficient for my needs.

A quick google search gave me an estimate of a 300:1 cost ratio of iron to silver (1 lb iron costing ~300 lb silver) in the 14th century. For comparison, a king's annual income might have been 20,000 lbs of silver. Without fossil fuels, smelting iron ore requires lots of charcoal, which requires lots and lots of wood, which requires plenty of land and labor (ever chopped a tree down by hand?). Bicycles would have been prohibitively expensive before fossil fuels.

Comment by jay-molstad on Is the "business cycle" an actual economic principle? · 2019-06-19T21:50:39.378Z · score: 3 (2 votes) · LW · GW

There are certainly economic theories that account for business cycles. Keynes's General Theory of Employment, Interest, and Money is the go-to book here.

If you expect the market to fall, you would want a short position. If the market continues to rise, that bet will lose lots of money. A bet against the market has to be very well timed, and that's very hard to do. As the saying goes, the market can stay irrational longer than any investor can stay solvent.

I completely agree with the answer above. I'll also add that, on an object level, all of the models agree about the outcomes of every experiment we've ever been able to do. It really doesn't matter whether you think of an isotope as having a 50% chance of decaying within 12 years, or whether you think of yourself as having a 50% amplitude, over the next `12 years, of branching into universes where the nucleus has decayed. As Feynman put it, "shut up and calculate" - the models work, but asking what they mean is a one-way ticket to epistemology.

Some of this seems to be a problem intrinsic to meritocracies. The people who get to positions of real authority in a competitive, meritocratic system have been trained for decades to ignore the losers disappearing in the rearview mirror while using their current position of authority primarily as a platform to push for their next promotion. Those are terrible habits for a society to cultivate in its leaders.

It seems to me that both parties to the Cold War favored the defect-defect outcome (launch all the nukes) over the cooperate-defect outcome (we die, they don't). It's hard to tell, though, because both sides had an incentive to signal that preference regardless of the truth.

But that's an extreme case. Any war you choose will have each side choosing between continuing to fight and surrendering. The cooperate-cooperate outcome (making peace in a way that approximates the likely outcome of a war) is probably best for all, but it's hard to achieve in practice. And it seems to me that at least part of the problem is that, if one side chooses to cooperate (sue for peace and refrain from maximally fighting), they run the risk that the other side will continue to defect (fight) and seize an advantage.
