April Coronavirus Open Thread

Some more on proning in this NYT article:

Some patients, by taking oxygen and rolling onto their sides or on their bellies, have quickly returned to normal levels. The tactic is called proning.
[...]
At Lincoln Hospital in the Bronx, Dr. Nicholas Caputo followed 50 patients who arrived with low oxygen levels between 69 and 85 percent (95 is normal). After five minutes of proning, they had improved to a mean of 94 percent. Over the next 24 hours, nearly three-quarters were able to avoid intubation; 13 needed ventilators. Proning does not seem to work as well i

April Coronavirus Open Thread

Something to keep an eye out for:

we also predict that the virus may invade multiple brain tissues, which may help explain to the loss of taste and smell in infected individuals. Has anyone seen evidence of further brain damage in COVID-19 patients? Please share if you do!
Also unexpected is the prediction that the virus may be able to invade the reproductive system (vagina, uterus, testis, cervix, ovary). Has anyone seen evidence for this? Please share if you do.
The COVID-19 targets do not show significant overlap with any major disease module (we tested it

"The Case for Universal Cloth Mask Adoption & Policies to Increase the Supply of Medical Masks for Health Workers"

Excerpt from Twitter thread summarizing it:

We have very good evidence that universal adoption of cloth masks will combat the spread of the virus. Specifically, we know that 1) asymptomatic people spread the virus, 2) mask wearing by infected people prevents them from transmitting the virus (the report provides citations).
How large are the benefits? Even if masks reduce transmission probabilities by only 10% (and as you'll see

It seems to me like this study wasn't very good and I've been more convinced by the rebuttals, such as this one:

Seeing the Smoke

The tone of this post, including the title, reminds me of an exchange between two characters on the TV show Deadwood (HBO, 2004-2006):

Wild Bill Hickok:
You know the sound of thunder, don't you, Mrs. Garrett?

Alma Garrett:
Of course.

Wild Bill Hickok:
Can you imagine that sound if I asked you to?

Alma Garrett:
Yes I can, Mr. Hickok.

Wild Bill Hickok:
' Your husband and me had this talk, and I told him to head home to avoid a dark result. But I didn't say it in thunder. Ma'am, listen to the thunder.

Rationality Quotes May 2012

“Smart people learn from their mistakes. But the real sharp ones learn from the mistakes of others.”

― Brandon Mull, Fablehaven

6wadavis8yOthers rarely collect enough data when making mistakes. Sometimes you need to go make the mistake yourself.

The real sharp ones also learn from the mistakes of others.

Rationality Quotes May 2012

“No matter how busy you may think you are, you must find time for reading, or surrender yourself to self-chosen ignorance.”

  • Confucius

"Well it's alright for you, Confucius, living in 5th Century feudal China. Between all the documentation I have to go through at work, and all the blogs I'm following while pretending to work, and all the textbooks I have to get through before my next assignment deadline, I don't have time to read!"

Rationality Quotes November 2011

The correctness of a decision can’t be judged from the outcome. Nevertheless, that’s how people assess it. A good decision is one that’s optimal at the time it’s made, when the future is by definition unknown. Thus, correct decisions are often unsuccessful, and vice versa.

--Howard Marks, The Most Important Thing p.136 (about investing, but applies to other things)

I don't remember exactly, but I think it was from a conference where he was speaking with Eliezer on a panel or Q&A, so that might be it.

Rationality Quotes October 2011

My understanding is that the advice is to be aware that you could also end up dead, so you should dig an extra grave for yourself. It's not practical advice, it's a warning that revenge is dangerous and not worth it.

Rationality Quotes October 2011

Before you embark on a journey of revenge, dig two graves.

-Confucius

They say when you embark on a journey of revenge, dig two graves.

They underestimate me.

-A Softer World

9wedrifid10yThat's terrible advice. Far better to spend that time thinking of a better attack plan. Make sure it includes contingencies to deal with anyone who may wish to avenge whoever you are killing.

Rationality Quotes September 2011

“When you’re young, you look at television and think, There’s a conspiracy. The networks have conspired to dumb us down. But when you get a little older, you realize that’s not true. The networks are in business to give people exactly what they want. That’s a far more depressing thought. Conspiracy is optimistic! You can shoot the bastards! We can have a revolution! But the networks are really in business to give people what they want. It’s the truth.”

-Steve Jobs, [Wired, February 1996]

0Juno_Watt8yIsn't that disproved by paid-for networks, like HBO? And what about non-US broadcasters like the BBC?
0private_messaging8yHe was the guy who thought that people were too dumb to operate a two-button mouse. It's not that the networks conspired to dumb us down, and it's not that people want something exactly this dumb, but it's that those folks in control at the networks, much like Jobs himself, tend to make systematic errors such as believing themselves to be higher above the masses than is actually the case. Sometimes that helps to counter the invalid belief that people will really want to waste a lot of effort on your creation.
1PhilGoetz10yIt's still an open question how well the networks succeed at giving people what they want. We still see, for instance, Hollywood routinely spending $100 million on a science fiction film written and directed by people who know nothing about science or science fiction, over 40 years after the success of Star Trek proved that the key to a successful science fiction show is hiring professional science fiction writers to write the scripts.

Rationality Quotes July 2011

Unless there are two horseshoe quotes, this one seems to be disputed:

http://en.wikiquote.org/wiki/Niels_Bohr#Disputed

4ata10yI (or someone) should update that page; the earliest source of the horseshoe story that I know of is from a 1927 essay by Heisenberg: Edit: Actually that date is almost definitely wrong, the essay refers to a conference that took place in 1927, probably wasn't given there. The earliest Google Books result for this quote is Heisenberg's 1969 autobiography, though, so that's still earlier and more authoritative than any of the sources given on the Wikiquote page.
Rationality Quotes July 2011

One of the most serious problems with modern "management" is that the incentives are all wrong. Imagine that I hire a programmer and pay him by the line of code. This idea has been so thoroughly debunked that it is nearly impossible to write out the consequences without sounding cliché. Yet it happens all the time: Companies promote "Architects" who are evaluated by the weight of their "architecture." The result is stultifying and demoralizing. The architect does not work to facilitate the programmer's work, he works to produ

7djcb10yHmmm, maybe a bit of an overgeneralization? Or a US-thing? I've never seen a manager being rewarded for the amount of "process" they impose on their team. I'm sure there are many bad managers, but it's also somewhat of a cliché for programmers to blame management for the parts of the work they don't like.
0lessdazed10yIt also produces comic strips. So it's not all bad.
Rationality Quotes July 2011

One perennial problem is the overwhelming incentive for analysts to issue “Buy” recommendations. The universe of stocks not owned by a customer is always much larger than the list of those currently owned. Consequently, it’s much easier to generate commissions from new “Buy” recommendations than from recommendations to sell.

-Joel Greenblatt

That whole "buying" vs "selling" dichotomy does nothing but cause problems. Let's just treat selling as buying negative stock.

Rationality Quotes: June 2011

It can be that, but I think it also illustrate the importance of understanding people's real goals and intentions and not assuming that they are what they appear to be at first glance.

Rationality Quotes: June 2011

"At one of our dinners, Milton recalled traveling to an Asian country in the 1960s and visiting a worksite where a new canal was being built. He was shocked to see that, instead of modern tractors and earth movers, the workers had shovels. He asked why there were so few machines. The government bureaucrat explained: “You don’t understand. This is a jobs program.” To which Milton replied: “Oh, I thought you were trying to build a canal. If it’s jobs you want, then you should give these workers spoons, not shovels.”

-Milton Friedman story

2grendelkhan9yThe earliest known citation of the anecdote is from 1935, quoting Canadian William Aberhart [http://quoteinvestigator.com/2011/10/10/spoons-shovels/]. Milton Friedman certainly told the story, and may have invented the somewhat snappier form quoted here. (Interestingly, William Aberhart was speaking for the Social Credit Party, which was hardly libertarian.)
7Document10ySeems like more of a libertarianism quote to me.

A few points come to mind:

  • Presumably they also wanted a canal and there may well be an optimum point where you maximize some sort of combined utility
  • Jobs programs, even those that create nothing particularly useful, are about giving people a sense of worth and accomplishment, otherwise you could just hand out money. Obviously futile make-work activities like the one suggested achieve the opposite of that and are, indeed, often deliberately used to punish and humiliate people.
9James_K10yFor the record, I'm pretty sure this story is apocryphal, though that doesn't take away from it's value as a rationality quote.
Rationality Quotes: June 2011

"The more you sweat in training, the less you bleed in war."

--WSJ article about Navy SEALs

-2simplyeric10yIt's an interesting point but exceedingly simplistic, more so these days than ever before. What about "the more you think in training", or "the more you learn in training"? Don't get me wrong, I'm not denying the value of sweat (excerise, fitness, etc), I'm just saying it's not even close to the whole equation.
5khafra10yI wonder how many other people on LW heard this quote first while in the process of sweating in training; and how many other military aphorisms could be repurposed this way.
Rationality Quotes: June 2011

The way to maximize outcome is to concentrate on the process.

The Best Textbooks on Every Subject

I've added it to my list. I'm currently reading Poor Charlie's Almanack and liking it a lot so far.

The best business book I've read is probably The Essays of Warren Buffett (second ed.), but it's certainly not exhaustive in what it covers.

Update: I've got my copy from Amazon.ca (really fast shipping - 2 days). Will probably have a chance to read it in February.

Rationality Quotes: January 2011

That's a good question. If I had to guess, I would say that most people used to be familiar with the domestic turkey that is being fattened for thanksgiving dinner (or whatever), and those probably can't fly very well, if at all.

Rationality Quotes: January 2011

In a strong enough wind, even turkeys can fly.

-Saying of investors

2simplyeric11yTechnically off-topic...but I've never understood why people think turkeys can't fly. I've even seen an ornithologist quoted in the NYTimes saying it (when a live turkey was found on an upper level balcony). Maybe it's just domesticated turkeys...but I've definitely seen wild turkeys fly (and no, it's got nothing to do with the whiskey). Which brings me to an interesting (to me) question: why do people base a piece of "wisdom" on a reference that is untrue to begin with? [and in closing: You don't win friends with salad.]

I've heard a similar aeronautical saying: Of course pigs can fly, they just need sufficient thrust.

Rationality Quotes: January 2011

Take the bettors in the racetrack experiment. Thirty seconds before putting down their money, they had been tentative and uncertain; thirty seconds after the deed, they were significantly more optimistic ans self-assured. The act of making a final decision--in this case, of buying a ticket--had been the critical factor. Once a stand had been taken, the need for consistency pressured these people to bring what they felt and believed into line with what they had already done. They simply convinced themselves that they had made the right choice and, no doubt, felt better and it all.
