The probabilistic forecasts debate -- That's nice fellows, but I'm kinda focused on that iceberg

Andrew has a good breakdown of the debate over probabilistic election forecasts if you're interested. Here's why I think you shouldn't be.

1. At this point, economists have so thoroughly screwed up the discussion of rationality that I now make a conscious effort to avoid the term “rational,” much as I try not to use “significance” except in the technical sense. Rational actor arguments routinely rely on simplifying assumptions that are never observed in real life and which exclude most of what we would think of logical thinking.

2. That said, any reasonable “rational choice” model has got to address the accuracy and completeness of the information available to the actors. For people who relied on 538, perceived and actual closeness matched up fairly well and it makes a fair amount of sense to talk about “rational” voting behavior. For people who relied on NYT’s Upshot and Slate’s real-time exit polls, not so much…

3. With this in mind, this whole debate over probabilistic forecasts strikes me as another one of those secondhand smoke on the Titanic questions that are eating away at our collective decision making ability. We have larger and more immediate concerns.

Even with good data and solid analysis, it seems obvious to me that the social good of horse race coverage is U-shaped. A reasonable amount provides useful information and helps voters converge on a generally satisfactory choice. Too much (either probabilistic or old school) overwhelms the process and creates a noisy feedback loop. Even if we were getting good information we’d still be on the wrong side of the U, and we aren’t getting good information.

4. It’s convenient to blame the voters for being “irrational” but given the crap they’ve been fed, it’s difficult to see how they can reasonably be expected to make intelligent decisions. We have supposedly serious organizations like the New York Times giving oxygen to joke candidates.



Billionaire vanity campaigns crowding out viable options. Millions of early votes wasted because someone thought it would be a good idea to have Super Tuesday three goddamn days after the first real primary of the election (no one takes NH seriously). And, of course, a level of noise that would strain even a well running system.

Some post-Saturday, pre-Tuesday thoughts

Back in September, my co-blogger and I were having a conversation about worst possible case scenarios for the Democrats. He suggested a third party candidate. I went with having the Democratic nominee collapse shortly before the election. I was thinking about Biden at the time, but having an even older candidate actually have a heart attack didn’t lessen these concerns. 

I’m not sure if any of the chattering class have seriously thought through the implications of the Democrat’s electability focus. In the general election, this is all to the good, but in the primary, it can create all sorts of problems as the selection process frequently degenerates into a pure Keynesian beauty contest which can drown out real content and produce alarming levels of feedback driven noise. This can delay convergence on the best choice, particularly if…

The people covering the primary are a bunch of noise chasing idiots.

The noise and feedback issues remind us that the decision to move up California’s primary was incredibly bad. The idea that California needed more influence was insane on its face. In general, we give too little time for the tough part of the process and lengthened the part that was too long already, pursuing the mythical swing voter.

We also need to stop wasting oxygen on joke campaigns. Any system where Steyer, Yang, and Williamson don't drop out long before Booker, Harris, and Castro  is broken .

"Just as hard as I could" -- Ben Cooper 1933-2020

Support Your Local Sheriff is the better movie -- less cartoonish and it holds together better -- but if you're looking for a complete dismantling of the Western hero, you'd be hard pressed to find a more thorough job than the follow-up, Support Your Local Gunfighter.






Though the comedy is much drier, Paddy Chayefsky's The Americanization of Emily (Garner's personal favorite) had a similar take on military honor, and produced one of the few really good anti-war films.

Repost: We'll be coming back to this.

One of the many discouraging things about the fight to address climate change and ocean acidification is that while the facts are overwhelmingly on the movement's side, it's narrative are increasingly handed over to people who traffic in questionable arguments and misinformation.

David Wallace-Wells, autism and bad science

David Wallace-Wells has been catching a lot of flack (most of it richly deserved) for his recent New York Magazine article on climate change. It is a hugely troubling sign when the very scientists you were claiming to represent push back against your article.

This controversy illustrates a larger problem with science reporting at the magazine. We already have a post in the queue discussing the neutral-to-credulous coverage of topics ranging from homeopathy to magic crystals to Gwyneth Paltrow's goop empire. The Wallace-Wells piece takes things to another level and goes in a very different but arguably worse direction. Rather than giving bad science a pass, he takes good science and presents it so ineptly has to do it a disservice.

I am not going to delve into that science myself. The topic has been well covered by numerous expert and knowledgeable writers [see here and here]. The best I could offer would be a recap. There are some journalistic points I may hit later and I do want to highlight a minor detail in the article that has slipped past most critics, but which is perfectly representative of the dangerous way Wallace-Wells combines sensationalism with a weak grasp of science.

Other stuff in the hotter air is even scarier, with small increases in pollution capable of shortening life spans by ten years. The warmer the planet gets, the more ozone forms, and by mid-century, Americans will likely suffer a 70 percent increase in unhealthy ozone smog, the National Center for Atmospheric Research has projected. By 2090, as many as 2 billion people globally will be breathing air above the WHO “safe” level; one paper last month showed that, among other effects, a pregnant mother’s exposure to ozone raises the child’s risk of autism (as much as tenfold, combined with other environmental factors). Which does make you think again about the autism epidemic in West Hollywood.


No, David, no it doesn't.

I want to be painstakingly careful at this point. These are complex and extraordinarily important issues and it is essential that we do not lose sight of certain basic facts: by any reasonable standard, man-made climate change is one of the two or three most important issues facing our country; the effect of various pollutants on children's mental and physical development should be a major concern for all of us; high ozone levels are a really bad thing.

But the suggestion that ozone levels are causing an autism epidemic in West Hollywood is both dangerous and scientifically illiterate. You'll notice that I did not say that suggesting ozone levels cause autism is irresponsible. Though the study in question is outside of my field, the hypothesis seems reasonable and I do not see any red flags associated with the research. If Wallace-Wells had stopped before adding that last sentence, he would've been on solid ground, but he didn't.

Autism is frightening, mysterious, tragic. This has caused people, particularly parents facing one of the worst moments imaginable, to clean desperately to any explanation that might make sense of their situation. As a result, autism has become a focal point for bad science, culminating with the rise of the anti-vaccination movement. There is no field where groundless speculation and fear-mongering are less welcome.

So, if ozone and other pollutants may contribute to autism, what's so bad about the West Hollywood claim? For that, you need to do some rudimentary causal reasoning, starting with a quick look at ozone pollution in Southern California.

Here are some pertinent facts from a 2015 LA Times article:

EPA Administrator Gina McCarthy selected a limit of 70 parts per billion, which is more stringent than the 75 parts-per-billion standard adopted in 2008 but short of the 60-ppb endorsed by environmentalists and health advocacy groups including the American Lung Assn. The agency’s science advisors had recommended a limit lower than 70 -- and as low as 60.

...


About one-third of California residents live in communities with pollution that exceeds federal standards, according to estimates by the state Air Resources Board.


Air quality is worst in inland valleys, where pollution from vehicles and factories cook in sunlight to form ozone, which is blown and trapped against the mountains.


The South Coast air basin, which includes Los Angeles, Orange, Riverside and San Bernardino counties, violated the current 75-ppb ozone standard on 92 days in 2014. The highest ozone levels in the nation are in San Bernardino County, which reported a 2012-2014 average of 102 parts per billion.


Now let's look at some ozone levels around the region. West Hollywood, it should be noted, is not great.





But just over the Hollywood Hills, the situation is even worse.



Go further inland to San Dimas and the level is even higher…






Higher still in Riverside ...






Though still far short of what we find in San Bernardino.



If you look at autism rates by school district and compare them to ozone levels, it is difficult to see much of a relationship. Does this mean that ozone does not contribute to autism? Absolutely not. What it shows is that, as with many developmental and learning disabilities, the wealthy are overdiagnosed while poor are underdiagnosed. It is no coincidence that a place like Santa Monica/Maibu (a notorious anti-vaxxer hotspot) has more than double the diagnosis rate of San Bernardino.

The there's this from the very LA Times article by Alan Zarembo that Wallace-Wells cites [emphasis added]:

 Irva Hertz-Picciotto, an epidemiologist at UC Davis, suspects that environmental triggers such as exposure to chemicals during pregnancy play a role. In a 2009 study, she started with a tantalizing lead — several autism clusters, mostly in Southern California, that her team had identified from disability and birth records.

But the hot spots could not be linked to chemical plants, waste dumps or any other obvious environmental hazards. Instead, the cases were concentrated in places where parents were highly educated and had easy access to treatment.

Peter Bearman, a sociologist at Columbia University, has demonstrated how such social forces are driving autism rates.

Analyzing state data, he identified a 386-square-mile area centered in West Hollywood that consistently produced three times as many autism cases as would be expected from birth rates.

Affluence helped set the area apart. But delving deeper, Bearman detected a more surprising pattern that existed across the state: Rich or poor, children living near somebody with autism were more likely to have the diagnosis themselves.
Living within 250 meters boosted the chances by 42%, compared to living between 500 and 1,000 meters away.

The reason, his analysis suggested, was simple: People talk.
They talk about how to recognize autism, which doctors to see, how to navigate the bureaucracies to secure services. They talk more if they live next door or visit the same parks, or if their children go to the same preschool.

The influence of neighbors alone accounts for 16% of the growth of autism cases in the state developmental system between 2000 and 2005, Bearman estimated.

In other words, autism is not contagious, but the diagnosis is.

Electability

This is Joseph

Ok, I am bracing for being taken down by Mark, but I wanted to comment on one of my current pet peeves.

There is a presidential primary going on right now. One of the big issues I keep hearing is whether a candidate is "electable". Now, historically speaking this might have been a valid concern. From Wikipedia:
The impetus for national adoption of the binding primary election was the chaotic 1968 Democratic National Convention. Vice President Hubert Humphrey secured the Presidential nomination despite not winning a single primary under his own name.
So in earlier eras it was a reasonable concern that the delegates at the convention might not be a representative sample of the voting population. Now primaries today are not necessarily representative of the electorate as a whole, but they are broadly based elections. It's pretty clear that anybody who wins a primary is "electable" in some important sense of the term.

Now, I think that this argument is a proxy for what people don't want to say out loud. All candidates who are able to win the primary do it from a combination of "crossover appeal" (get the other side to vote for you) and "enthusiasm" (get more of your base to run out and support you). In general, these things tend to be negatively correlated. Making your core supporters super-happy is often in conflict with reaching across the aisle.

In the small number of cases where this is not true, there doesn't tend to be much life in such a proposal. Both parties are united in not wanting to return big pieces of the country to Mexico, and you will note the absence of such proposals.

So I loathe the term "electable" in this context. Instead, I want the more precise discussion of the trade-off between exciting people and building bridges. Anybody who can survive the primary process looks like they are at least potentially "electable" to me. We'd probably all have had a clearer view in 2016 if we'd remembered that about Donald Trump.

Daycare and what does work pay for?

This is Joseph

So, I have a philosophical question. It is clear that work places benefit from having a robust set of benefits for workers, many of which make a lot more sense given as a employer benefit rather than as a part of cash compensation. In the United States, for example, the current regulatory system favors employer sponsored health care (although I hear they are in the process of revisiting this assumption).

Other benefits are a lot more standard. For example, heating and/or air conditioning makes a big difference in an office. Parking is another case where you could just give employees money but liquidity issues might make that inefficient (is there a private parking vendor near work that employees could rent spots from? Will land use allow this?).

An interesting case in this rubric is daycare. On site daycare would make at least as much of a positive difference for workers as on-site parking. Not everyone uses parking and not everyone uses daycare, either, but it would be a broadly useful benefit. It is also quite possible to offer paid daycare just like many universities offer paid parking.

My question is what is it that has kept daycare from being in the same category as parking for workplace infrastructure? Marissa Mayer was famous for thinking that raising a child as CEO wasn't as bad as people predicted, but she had a daycare in the office next door. Now, she paid for the expenses but the typical employee does not have the option to pay for a daycare in the same building, even if they want to.

Is there a reason that this relatively big boost in workforce benefit is so rarely fully staffed? Most daycares I am looking at, in multiple cities, have difficult wait lists and are hard to coordinate with work locations. Can't this be improved?

Didn't even get to Thiel's Cato Institute essay on women's suffrage



This 2014 piece by Mark Ames on the relationship between the Holocaust denial movement and the Koch Brothers should be read in its entirety, but I wanted to highlight this section.

The Reason issue discussed here was from 1976. The provocative, contrarian rhetorical approach is familiar to anyone who has been following Robin Hanson. It’s a process that pretends to be a free intellectual inquiry but which always ends up attacking a liberal position and pushing the Overton Window to the right.

Of course, Reason and Hanson have something else in common.




It’s easy to dismiss the more clownish examples, but in today’s journalistic ecosystem, no one from the right is more than one degree of separation from respectability in the mainstream media. Pretty much every major press outlet (the New York Times, NPR, CNN) welcomes Koch-subsidized academics and pundits. For the serious news consumer, they are unavoidable.

Obviously, there are smart people doing serious work at places like the Manhattan Institute or George Mason University, but while we shouldn’t reject their work out of hand, for the sake of the discourse, we need to find a way of reminding ourselves that their funding comes from an initiative that promotes Holocaust deniers, rape apologists and other extremists and propagandists when they serve the agenda, and that even the most independent researchers in that world know that reaching the wrong conclusions too often will cost them.
There is a politics to all of this, a politics that's barely budged since the days of the American Liberty League: The goal is to discredit the New Deal and FDR, which can't be done effectively without discrediting FDR's most popular cause, the victory over fascist Germany and Japan. To far-right extraction industry billionaires like the Koch family, FDR and his New Deal politics were a kind of anti-business "holocaust," because the New Deal forced the long-dominant plutocrats to part with a portion of their wealth and political power. To the nation's Big Business oligarchs in the 1930s, FDR's New Deal reforms — breaking up the power of finance, trusts, and industrialists, while empowering labor unions —was a crime and a wound as raw in 1976 as it was in 1936.

For them, FDR was a tyrant and a criminal, an American Hitler, only no one else could see things their way, because the real Hitler was widely believed to be one of the worst figures in history. Therefore, libertarian "historical revisionism" had to convince these Americans that Hitler wasn't nearly as awful as they believed, which meant that the Holocaust couldn't have happened — if the goal was to discredit FDR and the New Deal.

North’s article appeals to another sensibility popular with libertarians (and the Boomer left): the cult of the anti-Establishment iconoclast, every self-absorbed middle-class Baby Boomer's fantasy. That cult of the iconoclast allows North to paint libertarianism's far-right "historical revisionism" as anti-Establishment Cool, more an expression of one's individuality than a political act. So if the boring, bad Establishment says Hitler was bad and World War II was good, then naturally the anti-Establishment maverick will question that. Gary North writes:

One topic—the ultimate litmus test of hardnosed World War II revisionism—has generally been skirted: Hitler. Was he a madman, diplomatically speaking? Was he exclusively responsible for the Second World War?”

Much of the Reason Holocaust denier propaganda is about promoting a new set of anti-authority voices to replace the Establishment’s. So Martin cites Holocaust deniers Paul Rassinier and Harry Elmer Barnes; and Gary North introduces Reason’s readers to Bay Area Holocaust denier David Hoggan, the “anonymous” author of the 1969 neo-Nazi book “The Myth of the Six Million”:

    “In American revisionist circles the most famous (or infamous) case has been that of David Hoggan, the Establishment’s number-one academic pariah of the revisionist camp...Hoggan’s thesis regarding the origins of the Second World War are straightforward, and completely unorthodox. The primary villain was not Hitler; it was Lord Halifax, the British Foreign Secretary.”


North is a clever huckster who’s studied his Baby Boomer audience, so he uses marketing words that he knows appeal to his target consumer: “unorthodox,” “Establishment’s number-one academic pariah,” and weirdest of all for a strict Old Testament theofascist like North, he even uses the then-popular hippie expression “far-out” (meaning “cool") to sell Holocaust denial:

    “Probably the most far-out materials on World War II revisionism have been the seemingly endless scholarly studies of the supposed execution of 6 million Jews by Hitler. The anonymous author [Hoggan] of ‘The Myth of the Six Million’ has presented a solid case against the Establishment’s favorite horror story—the supposed moral justification for our entry into the war.”

These next few tweets go to a longstanding problem with the New York Times and its place in the ecosystem. As many including Josh Marshall have observed, the NYT has a way of coming late to a story and downplaying the work that came before. Because of the paper's standing, from that point on, it's "as reported by the New York Times."



My impression is that the conservative think tank world initially built up Hanson as a deep thinker assuming he'd be useful for moving the Overton Window, Unfortunately, Hanson has been too big of a attention junkie/clown to be effective.


In 1632, Rasputin would have been considered mildly unlucky.


I know I'm not supposed to call Robin Hanson creepy because that would be mean. How about this? Can I call this creepy?



Could Bernie's branding help him in the primaries but hurt him in the general?


Worth a look.


As we've been pointing out for the past decade, the black and white, us vs them worldview of the education reform movement left it vulnerable to corruption.




'“We remain neutral on geopolitical disputes and make every effort to objectively display disputed areas,” Russell said in the statement. “In countries where we have local versions of Google Maps, we follow local legislation when displaying names and borders.”'


My favorites are the pundits who go from one set of absolute certainties to another completely contradictory set without the slightest pause for doubt, humility or reflection.

High SF housing prices are forcing Silicon Valley workers to make slightly shorter commutes

Just to get the obvious out of the way, California needs to build more housing. Rents are too high and the situation with the homeless is becoming a genuine humanitarian crisis. Unfortunately, as with climate change, the very seriousness of the problem sometimes makes people reluctant to criticize bad arguments, lest they be accused of minimizing the issue (see the reaction to the collected works of David Wallace Wells). The result is some truly silly ideas have lodged themselves into the standard narrative.

Case in point.  [Emphasis added]
Welcome to life on Silicon Valley's new frontier. When tech companies first introduced private shuttles for their employees more than a decade ago, they served the affluent neighborhoods in San Francisco and the Peninsula. Now the buses reach as far as the almond orchards of Salida and the garlic fields of Gilroy.



"That just tells you the story of the Bay Area," said Russell Hancock, president and CEO of regional think tank Joint Venture Silicon Valley. "We're going to be in these farther-flung places, and that's our reality because we're not going to be able to create affordable housing."

...


A few miles into Alameda County, a fairgrounds parking lot has been transformed into a massive park-and-ride operation. A laundry list of tech companies — Google, Facebook, Amazon, Netflix and others — send shuttles here or nearby train stations, according to a report prepared for the Alameda County Transportation Commission. Around 7 a.m., people in puffy jackets and backpacks jog to a silver bus with its destination displayed as Wolfe Road in Sunnyvale, where Apple has a large campus.

We need to talk about the word “farther” because in this context, it is more of a cultural than a physical concept. Go online and check out the distance and rush-hour driving times from Silicon Valley towns like Sunnyvale to either San Francisco or Gilroy and you’ll find that the differences aren’t great and that Gilroy is often closer.

A great deal of the discussion of Bay Area housing and infrastructure is based on the implicit assumption that Silicon Valley is next to San Francisco rather than 40 or so miles away. It’s not even the closest big city (San Jose is considerably larger).

Nonetheless, Bay Area residents still refer to it as “the City” and the other towns continue to have an inferiority complex that as an Angeleno I’ve always found a bit odd, as if it were 1900 and it was the only outpost of culture west of the Continental Divide.

Whatever its origins, the mystique of San Francisco has badly muddled people's thinking about the housing crisis, and this is a problem that requires clear thinking.

RIP Robert Conrad, good work Kai Ryssdal

At the risk of getting lots of angry comments, Star Trek makes the top ten my best of 60s TV list. This spy-fi/proto-steampunk series makes the top five.






This episode of Marketplace had three stories I was thinking about blogging...

The business and business metrics of music and streaming about 10 minutes in. If nothing else, check out the chutzpah of Justin Bieber.

Wal-Mart will now deliver to your home while you're not there about 20 minutes in. It's not quite as creepy as it sounds but, with the tight margins of the grocery business, it's not easy to see how they expect to turn a profit. Given that the two big players in this are Wal-Mart and Amazon, I wouldn't rule out a purely anti-competitve play to drive smaller competitors out of business.

And finally the show ends with an interesting new hiring policy at the Body Shop retail chain.

The Saudi sovereign wealth fund bet big on Uber.. That didn’t work out too well for them. Then they backed WeWork. This time though, I think they picked a winner.

As I've said before, serious money is starting to change hands here.

"Saudi Arabia, Virgin Hyperloop One to conduct world’s first national hyperloop study"

RIYADH: A groundbreaking study will be conducted to build the world’s longest hyperloop track,  the Ministry of Transport announced on Thursday.

It said an agreement with Virgin Hyperloop One (VHO), the world’s leading hyperloop company, would see a groundbreaking pre-feasibility study conducted on the use of hyperloop technology, laying the groundwork for a network of routes across Saudi Arabia.

The study is the first to be carried out anywhere in the world [I assume they mean the first on this scalee – MP] and will examine viable routes, expected demand, anticipated costs and explore the socioeconomic impact, such as the creation of jobs and environmental effects.

...

“We have a vision for the Kingdom, and that vision is of connecting it and the Gulf with the ability to travel from Riyadh to Jeddah in 46 minutes, to Neom from Jeddah in 40 minutes, from Riyadh to Dammam and Jubail in 28 minutes, and to go beyond the Kingdom, from Riyadh to Abu Dhabi, in 48 minutes.     

“It’s not just about providing a future transportation system, it’s the ecosystem behind it. What we want to do is to be able to bring technology to the Kingdom to be able to share and develop that knowledge. We signed an agreement with King Abdullah Economic City in October last year specifically to look at manufacturing, how we can actually bring technology, and that is expected to create about 124,000 jobs.”

Saudi Minister of Transport Saleh Al-Jasser said: “Crown Prince Mohammed bin Salman has outlined the role of transport in shaping the future of the Kingdom’s economy within Vision 2030. As we enter a new decade, we intend to make rapid progress in building the infrastructure required to define mobility for the future, enabling the efficient movement of people and goods. With the transformative hyperloop technology, Saudi Arabia will not only unlock unparalleled benefits for its people and the economy but will continue to lead the region into an era of prosperity.”

I started to make a "Vulture" joke, but I realized carrion play an important role in the ecosystem




This screen grab does a great job capturing so much of what’s wrong with the New York Magazine family and with business and entertainment journalism in general.

First off, there’s the article itself. Billed as an explainer, it’s nothing more than an especially embarrassing press release for a business model that makes WeWork look well thought out. It will take more than one post to explore the full awfulness of Quibi as an investment. For here, I’ll just say that this is possibly the stupidest proposal you’ll read involving the streaming industry, and that’s a high bar to clear.



Then there’s the sidebar. I’m sure I could think of a celebrity of comparable stature more despicable than  Gwyneth Paltrow if I tried, but none come to mind (and, no, that’s not an invitation for suggestions. I already spend too much time thinking about horrible people). She uses the press’ sycophancy toward the rich and famous and fascination with lifestyle porn to push flaky and sometimes  dangerous pseudoscience. The New York Magazine group has been playing footsie with quacks and new age charlatans for years (see here and here)

Finally there’s Netflix’s minor but still notable accomplishment of making the normal monthly cycling of shows in and out of rotation into a respectable news genre. Even HBO, which has long been extraordinarily good at working the press, was never able to get this kind of steady, extensive PR out of routine programming changes. We can’t exactly single out Vulture for this one but they certainly seem willing to play along.
