Larry Elder’s campaign for governor hit with accusations of “white supremacism”

In City Journal, Heather Mac Donald looks at the recent hysterical attacks on gubernatorial hopeful Larry Elder based on the notion that he is somehow a kind of stalking horse for white supremacists:

The possibility that Larry Elder may win California’s recall election against Governor Gavin Newsom is generating acute anxiety in the mainstream media and among the activist Left. Elder’s foes are responding with their favored means of destruction: by playing the race card. Never mind that the nationally syndicated talk show host is black. A series of opinion columns and editorials have accused him of being a white supremacist, or at the very least a shill for other white supremacists. Elect Elder and California will reinstate Jim Crow, state senator Sydney Kamlager, a Democrat from Los Angeles, has warned.

The media have focused particularly on Elder’s views about crime and policing. The self-described “Sage from South-Central” maintains that criminals, not the police, are the biggest threat in the black community. According to Elder, the false narrative about lethal police racism has only led to more black homicide deaths. “When you reduce the possibility of a bad guy getting caught, getting convicted and getting incarcerated, guess what? Crime goes up,” he said recently at a campaign event in Orange County.

Elder also rejects the charge that white civilians are gunning down blacks, as LeBron James maintained in a tweet during the George Floyd riots: “We are literally hunted everyday, every time we step outside the comfort of our homes.” Elder has a different take. If a “young black man is eight times more likely to be killed by another young black man than [by] a young white man,” Elder told the Orange County Republicans, then “systemic racism is not the problem.”

Such statements are anathema to the establishment Left, deeply invested as it is in the idea that blacks have little agency in the face of ubiquitous white racism. Few subjects are more taboo in elite discourse than the elevated rate of crime among blacks, as it suggests cultural pathologies that — at the very least — complicate the victim narrative. To the Left, black crime is little more than a racist fiction. Los Angeles Times columnist Jean Guerrero claims that the crime statistics Elder has cited “over the decades to support his views and policy proposals are misleading, if not outright false, casting Black people as unusually crime-prone.” Black people are not “more inclined toward violent crimes,” nor do blacks “disproportionately victimize whites,” Guerrero wrote, citing Columbia law professor Jeffrey Fagan and other criminal experts. (Fagan was the plaintiff’s expert in a trilogy of lawsuits against the New York Police Department in the 2010s.) Fellow Times columnist Erika Smith sneered that Elder “keeps trotting out statistics that purport to show that Black people are particularly prone to murdering one another.”

Unfortunately for Elder’s critics, the statistics showing vastly disproportionate rates of black crime and victimization come from some of the Left’s favorite sources. CDC data show that in 2015, for example, the homicide victimization rate for blacks aged 10–34 (37.5 per 100,000) was 13 times the rate for whites (2.9 per 100,000). That disparity is undoubtedly much greater now, given the record-breaking increase in homicides since the George Floyd riots — an increase disproportionately affecting blacks.

Those black victims of homicide are not being killed by cops or whites. They are being killed by other blacks. In Los Angeles, blacks this year have committed 46 percent of homicides whose offender is known, even though they are just 9 percent of the Los Angeles population. Whites make up 28 percent of the Los Angeles population but have committed 4 percent of homicides, mostly involving domestic violence. These data, reported by the Los Angeles Times, mean that a black Angeleno is 35 times more likely to commit a homicide than a white Angeleno. Homicide data are the gold standard for crime statistics. Alas for Jeffrey Fagan and the Los Angeles Times‘s other experts, the statistical conclusion that blacks are “more inclined toward violent crimes” is indisputable.

The initial findings of our months-long dietary natural experiment

Filed under: Britain, Food, Health — Tags: , , , — Nicholas @ 05:00

As we’ve all been told many, many times by the food nannies, access to fast food restaurants makes us fat. The food is too greasy, too salty, too tasty for our feeble wills to fight so we just engorge ourselves on those bad calories. We eat too much fast food and we get fat. Case closed. Well, that’s what we’ve been told. Our recent fast food deprivation diets say something else again:

“Camden Fast Food” by It’s No Game is licensed under CC BY 2.0

OK, well, we’ve just had a grand experiment, haven’t we? Peeps haven’t been able to queue at Maccy D’s to get their greaseburger. People have had to – and have had time to – buy actual food and then prepare it for themselves at home.

Which is something that does rather kill the case about those burgers. Because what has been happening is that we’ve been – in the absence of greaseburgers – been eating more.

No, really:

    Using data on millions of food and non-alcoholic drink purchases from shops, takeaways and restaurants, the study found that the pandemic led to calories from restaurant meals falling to zero during the UK’s first national lockdown. That increased somewhat over the summer and declined again as restrictions in the hospitality sector were reintroduced in the autumn.

    However, this was more than offset by a large increase in calories from takeaways, which peaked at more than double the usual levels in the UK’s second national lockdown in November 2020.

    Overall, people increased their calories from raw ingredients by more than those from ready-to-eat meals and snacks and treats, with the pandemic leading to a shift in the balance of calories towards foods that required home preparation.

It’s that last paragraph that’s important. More home food preparation was being done from raw ingredients. And yet calorie consumption rose.

The report said the most plausible explanation for the sustained increase over the pandemic was higher consumption rather than changes in household composition, food waste or stocking up.

The study is specific to Britain, but it’s highly likely that the same results will be observed in Canada, the United States, Australia, and many other places. But I wouldn’t expect it will be given much coverage, like so much these days that contravenes the messaging that our dying media all seem to prefer to spread.

Media Fearmongering

Filed under: Books, Britain, Government, Health, Media — Tags: , , , , , — Nicholas @ 03:00

Laura Dodsworth on how the BBC and other British media outlets turned all the dials to 11 to ramp up fear over the spread of the Wuhan Coronavirus:

The media have served us a cornucopia of frightening articles and news items about Covid-19 in 2020 and 2021. While writing my new book, A State of Fear: How the UK Government Weaponised Fear During the Covid-19 Pandemic, I encountered a panoply of doom-mongering headlines. These were an indication of the significant role the media have played in creating our state of fear.

Of course, news media should not shy away from reporting frightening news during a pandemic. They should make us aware of the numbers of deaths, the policies being implemented to tackle the pandemic and the latest scientific developments. But during Covid, the media went beyond reporting on the pandemic. Instead, they appeared beholden to the old commercial imperatives, “If it scares, it airs”, and “If it bleeds, it leads”. It seems fear does sell.

The anxious, frightened climate this has helped to create has been suffocating. Death tolls were constantly brandished without the context of how many people die every day in the UK, and hospital admissions were reported while recoveries were not. As a result, Covid often appeared as a death sentence, an illness you did not recover from – even though it was known from the outset that Covid was a mild illness for the majority of people.

Given the wall-to-wall doom, it is therefore no surprise that the British were one of the most frightened populations in the world. Various studies showed that we were more concerned than other countries about the spread of Covid and less confident in the ability of our government to deal with it. One survey in July 2020 showed that the British public thought between six and seven per cent of the population had died from Covid – which was around 100 times the actual death rate at the time. Indeed, if six or seven per cent of Brits had died from Covid, that would have amounted to about 4,500,000 bodies – we’d have noticed, don’t you think?

While researching A State of Fear, I interviewed members of the general public about how they were impacted by the “campaign of fear” during the epidemic. Many talked of how the media had elevated their alarm.

“There wasn’t much to do”, Darren told me, “so we’d watch TV and we saw programmes about disinfecting your shopping when it arrives, and having a safezone in the kitchen. The nightly bulletins on the TV about death tolls, the big graphs with huge spikes on them, came at us ‘boom, boom, boom!’. It was a constant barrage of doom and gloom. My fear of the virus went through the roof.”

Sarah told me she had to stop watching the BBC. As her daughter put it, “If you just watched or listened to the BBC every day, what hope would you have had?”. Jane, meanwhile, described the “gruesome headlines” that came at her “thick and fast”.

The fearmongering about Covid began even before the pandemic hit the UK. We were primed by videos from Wuhan in China, which were then widely circulated by UK-based media outlets. These painted an apocalyptic picture, featuring collapsed citizens, medics in Hazmat suits, concerned bystanders and a city grinding to a halt. In one memorable video, which went viral, so to speak, a woman fell, stiff as a board, flat on her face, on a pavement. The split second where she falters is a giveaway – this was a set-up. If the rest of the world had Covid, China had “Stunt Covid”.

Depression and suicide rates during the Wuhan Coronavirus pandemic

Filed under: Health, Japan, Science, USA — Tags: , , , — Nicholas @ 03:00

At Works in Progress, Scott Alexander looks at the details of rates of depression (which went up during the pandemic) and suicides (which surprisingly went down):

When COVID started spreading, life got more depressing, people became more depressed, but suicide rates went down. Why?

First, are we sure all of that is true? I won’t waste your time listing the evidence that life got more depressing, but what about the other two?

Ettman et al. conveniently had data from nationally representative surveys about how many Americans were depressed before COVID-19. They found another nationally representative sample and asked them the same questions in late March/early April 2020, when the first wave of US cases and lockdowns was at its peak. They found that 3 times as many people had at least one depression symptom, and 5–10x as many people scored in the range associated with “moderately severe” or “severe” depression.

This is a good study. It’s published in the Journal of the American Medical Association, a good journal. It’s been cited 50+ times in 6 months. Really the only thing anyone could have against it is the implausibly large effect it found. But it matches similar studies from Australia, Portugal, and around the world. Let’s say it’s real.

Along with the increased depression came an increase in people who said they were thinking about suicide. According to the US CDC, more than twice as many Americans considered suicide in spring 2020 compared to spring 2018 (10.7% vs. 4.3%).

Yet completed suicide rates stayed flat or declined. It’s hard to tell exactly which, because suicide is rare and noisy, and you need lots of data before anything starts looking statistically significant. But there are studies somewhere between “flat” and “declined” from Norway, England, Germany, Sweden, and New Zealand.

We also have two more complete reports from larger countries that help us see the pattern in more detail. First is Japan. Studies by Tanaka and Nomura broadly agree on a similar pattern — a slight decrease in suicides in the earliest stage of the pandemic (spring 2020) followed by a larger increase during the autumn. Here’s Nomura’s data:

The top graph is women, the bottom is men. The blue and red lines represent the 95% confidence range for an “average” year. Months that differ significantly from the average have little dots on top of their bars. You can see that April 2020 had significantly less suicide than average, among both genders, and July/August/September have more than average for women (and trend on the high side for men too).

Second is the US. The US Centers for Disease Control recently released their “nowcast” of 2020 deaths. These use the limited amount of data they have now to predict what the trends will look like once all the data comes in; their prediction process seems reasonable and we can probably treat the figures as canonical. Here’s their main result:

Suicide rates were pretty normal until March, when they dropped off pretty quickly and stayed low until midsummer. They’ve since hovered around normal again. Overall, suicides declined by 5.6%.

All these countries combine to form a picture of suicide rates dipping very slightly during the first and most frantic period of the pandemic — March to May — and then going back to normal (except in Japan, where things have since gotten worse). Thus the paradox: increasing depression combined with decreasing suicides. What’s going on?

When the science becomes problematic to the narrative

Filed under: Health, Media, Politics, Science, USA — Tags: , , , , — Nicholas @ 03:00

Alexander Riley looks at a few of those awkward points where actual “scientific” science conficts with the deeply held beliefs of the “I heart SCIENCE!” community:

… human and nature cannot so easily be pried apart. The evidence of the biological reality of the sex difference — not just in gonads and sex cells, but in personality characteristics and behavioral profiles, on average — is overwhelming, and science is daily producing more. Male and female brains are structurally different in ways that map on to the emerging neuroscientific knowledge on how brain structure affects behavior and capabilities. The feminist claim that these differences are wholly a product of socialization becomes more implausible the more we know. In societies where egalitarian gender ideology is arguably most widespread, such as in Northern Europe, there has been no disappearance of traditional sex differences in choices concerning careers. Men are still overrepresented in fields that focus on systems and objects, and women are still the overwhelming majority in fields dedicated to extensive human interaction and social services.

The radical spirit of ’90s feminism represented by [author Judith Butler’s] Gender Trouble did not stop at “deconstructing” gender in the effort to move toward a world in which gender roles are divorced from biological sex. Sex too had to be subjected to such “problematization.” Radicals used the writing of Anne Fausto-Sterling, a biologist who admitted her work was fundamentally shaped by her “1960s street-activist heart,” to suggest that the sex binary was also an oversimplified social construction. Fausto-Sterling insisted there are at least five sexes: males, females, “true hermaphrodites” with one testis and one ovary, male pseudohermaphrodites with testes and “some aspects of female genitalia” but no ovaries, and female pseudohermaphrodites with ovaries and “some aspects of male genitalia” but no testes. Perhaps, she asserted, several of every hundred people might be in one of the three intersex categories, with — the clincher — an “infinitely malleable continuum” between them.

It was quickly pointed out that Fausto-Sterling had been deceptive in her estimate of the frequency of intersexuality. Leonard Sax, in the Journal of Sex Research, noted that she had counted phenomena such as Klinefelter’s Syndrome (biological males with an extra X chromosome), Turner’s Syndrome (biological females with only one X chromosome), and several other conditions typically not recognized as intersex. One of these alone — late-onset congenital adrenal hyperplasia (LOCAH), which involves the overproduction of adrenal androgens — accounts for 90 percent of Fausto-Sterling’s claimed figure of 1.7 percent of the population that is intersex. But LOCAH is not an intersex phenomenon. Many individuals who have it are never diagnosed because the symptoms are so mild, and all who have it are born with typical male or female genitalia that correspond to the male and female genotypes. Nearly all such individuals go through puberty with the typical sexual development for their genotype, as the condition generally does not manifest in women until the early 20s and in men much later. The true estimate of intersex individuals, Sax argued, is roughly 0.018%, about 100 times lower than Fausto-Sterling’s estimate. That is, more than 99.98% of humans are clearly either male or female in terms of biological sex.

But the attack on “standard sex difference science” was undeterred by this decimation of Fausto-Sterling’s case. In Gender Trouble, Butler criticized the work of an MIT group that had just discovered the region on the Y chromosome responsible for sex differentiation, claiming these scientists ultimately had to invoke cultural symbols of patriarchy to legitimate their explanations. In her view, this betrayed the very notion of an objective science of sex difference. We are always trapped in culture, she wrote, which means we are always trapped in patriarchy. A science of sex is impossible. Radical sex/gender ideology attacked science as male knowledge and elevated female knowledge as superior on the basis that women as a class were treated as inferior. Like blacks and other powerless groups, women — at least, women with a feminist outlook — could critically understand the point of view of men and supplement its lacunae with the fuller vision of the female perspective. Marx made similar claims about the superiority of working-class consciousness, though he did not attempt to cast the very notion of science as a tool of oppression.

The MIT group’s finding that what we now know as the SRY gene determines sex is universally accepted science today, and Butler’s ideological criticism has aged poorly in scientifically literate circles. So has her wild overestimation that perhaps one in ten people is outside the normal sex binary.

QotD: Why “the rich” benefit more from tax cuts

Filed under: Economics, Government, Quotations — Tags: , , , , — Nicholas @ 01:00

It might be worth our giving a little explanation to The Guardian about how tax systems work. We impose taxes upon certain things. Activities, transactions, even at times unsuccessfully upon mere existence as with the poll tax. These taxes are then paid by those who indulge in such activities, perform such transactions, have the temerity to exist. If we then decide to cut the tax rate or level on an activity, type of transaction or mode of existence then it will be those who formerly paid the tax on such who benefit from the tax cut on such. This shouldn’t be all that difficult for people to understand but we do seem to have an entire newspaper devoted to not grasping the point […]

There is that objectionable idea that not taxing something is a giveaway. The root presumption there is that everything belongs to the State and we’re lucky it allows us to keep anything to deploy as we desire and not as those who stay awake in committee do. This is not an assumption that leads to a free country nor populace, nor a liberal society.

But it’s also to miss that logical point, that if income tax is to be reduced then it must be those currently paying income tax who benefit from not doing so in the future under the new rates. […] The low paid cough up hardly anything in income tax. Therefore the low paid gain hardly anything from income tax being reduced. This should be obvious.

Freddie DeBoer’s arguments against successful charter schools

Filed under: Books, Education, USA — Tags: , , , , — Nicholas @ 03:00

Scott Alexander’s extensive review of Freddie DeBoer’s book The Cult of Smart includes this discussion of DeBoer’s belief that American charter schools are fraudulent and only manage their headline-worthy educational outcomes by “cooking the books”:

I think DeBoer would argue he’s not against improving schools. He just thinks all attempts to do it so far have been crooks and liars pillaging the commons, so much so that we need a moratorium on this kind of thing until we can figure out what’s going on. But I’m worried that his arguments against existing school reform are in some cases kind of weak.

DeBoer does make things hard for himself by focusing on two of the most successful charter school experiments. If he’d been a little less honest, he could have passed over these and instead mentioned the many charter schools that fail, or just sort of plod onward doing about as well as public schools do. I think the closest thing to a consensus right now is that most charter schools do about the same as public schools for white/advantaged students, and slightly better than public schools for minority/disadvantaged students. But DeBoer very virtuously thinks it’s important to confront his opponents’ strongest cases, so these are the ones I’ll focus on here.

Success Academy is a chain of New York charter schools with superficially amazing results. They take the worst-off students — “76% of students are less advantaged and 94% are minorities” — and achieve results better than the ritziest schools in the best neighborhoods — it ranked “in the top 1% of New York state schools in math, and in the top 3% for reading” — while spending “as much as $3000 to $4000 less per child per year than their public school counterparts.” Its supporters credit it with showing “what you can accomplish when you are free from the regulations and mindsets that have taken over education, and do things in a different way.”

DeBoer will have none of it. He thinks they’re cooking the books by kicking out lower-performing students in a way public schools can’t do, leaving them with a student body heavily-selected for intelligence. Any remaining advantage is due to “teacher tourism”, where ultra-bright Ivy League grads who want a “taste of the real world” go to teach at private schools for a year or two before going into their permanent career as consultants or something. This would work — many studies show that smarter teachers make students learn more (though this specifically means high-IQ teachers; making teachers get more credentials has no effect). But it doesn’t scale (there are only so many Ivy League grads willing to accept low salaries for a year or two in order to have a fun time teaching children), and it only works in places like New York (Ivy League grads would not go to North Dakota no matter how fun a time they were promised).

I’m not sure I share this perspective. Success Academy isn’t just cooking the books — you would test for that using a randomized trial with intention-to-treat analysis. The one that I found is small-n, short timescale, and a little ambiguous, but I think basically supports the contention that there’s something there beyond selection bias. Teacher tourism might be a factor, but hardly justifies DeBoer’s “charter schools are frauds, shut them down” perspective. Even if Success Academy’s results are 100% because of teacher tourism, they found a way to educate thousands of extremely disadvantaged minority kids to a very high standard at low cost, a way public schools had previously failed to exploit. That’s not “cheating”, it’s something exciting that we should celebrate. If it doesn’t scale, it doesn’t scale, but maybe the same search process that found this particular way can also find other ways? Surely it doesn’t seem like the obvious next step is to ban anyone else from even trying?

And we only have DeBoer’s assumption that all of this is teacher tourism. Success Academy itself claims that they have lots of innovative teaching methods and a different administrative culture. If this explains even 10% of their results, spreading it to other schools would be enough to make the US rocket up the PISA rankings and become an unparalleled educational powerhouse. I’m not claiming to know for sure that this is true, but not even being curious about this seems sort of weird; wanting to ban stuff like Success Academy so nobody can ever study it again doubly so.

DeBoer’s second tough example is New Orleans. Hurricane Katrina destroyed most of their schools, forcing the city to redesign their education system from the ground up. They decided to go a 100% charter school route, and it seemed to be very successful. Unlike Success Academy, this can’t be selection bias (it was every student in the city), and you can’t argue it doesn’t scale (it scaled to an entire city!). But DeBoer writes:

    After Hurricane Katrina, the neoliberal powers that be took advantage of a crisis (as they always do) to enforce their agenda. The schools in New Orleans were transformed into a 100% charter system, and reformers were quick to crow about improved test scores, the only metric for success they recognize. Whether these gains stand up to scrutiny is debatable. But even if these results hold, the notion of using New Orleans as a model for other school districts is absurd on its face. When we make policy decisions, we want to isolate variables and compare like with like, to whatever degree possible. The story of New Orleans makes this impossible. Katrina changed everything in the city, where 100,000 of the city’s poorest residents were permanently displaced. The civic architecture of the city was entirely rebuilt. Billions of dollars of public and private money poured in. An army of do-gooders arrived to try to save the city, willing to work for lower wages than they would ordinarily accept. How could these massive overall social changes possibly be replicated elsewhere? And how could we have any faith that adopting the New Orleans schooling system — without the massive civic overhaul — would replicate the supposed advantages?

These are good points, and I would accept them from anyone other than DeBoer, who will go on to say in a few chapters that the solution to our education issues is a Marxist revolution that overthrows capitalism and dispenses with the very concept of economic value. If he’s willing to accept a massive overhaul of everything, that’s failed every time it’s tried, why not accept a much smaller overhaul-of-everything, that’s succeeded at least once? There are plenty of billionaires willing to pour fortunes into reforming various cities — DeBoer will go on to criticize them as deluded do-gooders a few chapters later. If billions of dollars plus a serious commitment to ground-up reform are what we need, let’s just spend billions of dollars and have a serious commitment to ground-up reform! If more hurricanes is what it takes to fix education, I’m willing to do my part by leaving my air conditioner on “high” all the time.

QotD: The (as-yet-unfulfilled) promise of “personalized medicine”

Filed under: Health, Quotations, Science — Tags: , , , — Nicholas @ 01:00

A more useful lesson might be skepticism about personalized medicine. Personalized medicine – the idea that I can read your genome and your blood test results and whatever and tell you what antidepressant (or supplement, or form of therapy) is right for you has been a big idea over the past decade. And so far it’s mostly failed. A massively polycausal model would explain why. The average personalized medicine company gives you recommendations based on at most a few things – zinc levels, gut flora balance, etc. If there are dozens or hundreds of things, then you need the full massively polycausal model – which as mentioned before is computationally intractable at least without a lot more work.

(You can still have some personalized medicine. We don’t have to know the causes of depression to treat it. You might be depressed because your grandfather died, but Prozac can still make you feel better. So it’s possible that there’s a simple personalized monocausal way to check who eg responds better to Prozac vs. Lexapro, though the latest evidence isn’t really bullish about this. But this seems different from a true personalized medicine where we determine the root cause of your depression and fix it in a principled way.)

Even if we can’t get much out of this, I think it can be helpful just to ask which factors and sciences are oligocausal vs. massively polycausal. For example, what percent of variability in firm success are economists able to determine? Does most of the variability come from a few big things, like talented CEOs? Or does most of it come from a million tiny unmeasurable causes, like “how often does Lisa in Marketing get her reports in on time”?

Maybe this is really stupid – I’m neither a geneticist or a statistician – but I imagine an alien society where science is centered around polycausal scores. Instead of publishing a paper claiming that lead causes crime, they publish a paper giving the latest polycausal score for predicting crime, and demonstrating that they can make it much more accurate by including lead as a variable. I don’t think you can do this in real life – you would need bigger Big Data than anybody wants to deal with. But like falsifiability and compressability, I think it’s a useful thought experiment to keep in mind when imagining what science should be like.

QotD: Banishing racism

Filed under: Liberty, Politics, Quotations, USA — Tags: , , , — Nicholas @ 01:00

The simple, powerful truth that banishes racist prejudice is this: the individual is not the mass. Statistical distributions do not predict the traits of individuals. It’s OK to acknowledge that (for example) Ashkenazic Jews average significantly brighter than gentile whites, because the difference in the means of those bell curves tells us nothing about where any single Jew or gentile falls on them.

We can – we must, in fact – learn to judge individuals as individuals, not as members of racial or other ascriptive groups. This has always been the right thing to do; as knowledge about genetic group differences becomes more detailed and widespread, we will need to learn how to focus rigorously on individuals with the same discipline (and the same justified fear of failure) that we now apply to averting our eyes from genetic group differences.

Part of the reason this evolution won’t be easy is that so much of our politics has been distorted by racial grievance-mongering. It’s not only the obvious bad guys like neo-Nazis, Black separatists like Louis Farrakhan, and Bharatiya Janata who are invested in racialist categorization as a lever to power. The political Left has fallen into a lazy habit of screaming “racist!” at anyone who disagrees with them, won’t readily relinquish that rhetorical club, and have a lot invested in the present system of taboo, resentment, “disparate impact” legislation, and racial identity politics; expect them, too, to be part of the problem rather than part of the solution.

Still, the right strategy is clear. Actual knowledge makes both prejudice and repression unsustainable. “Know thyself!” said the oracle, and behavioral genetics will allow – actually, force us – to know ourselves in ways we never have before. That way lies the pain of revelation, but also the path of redemption.

We know, from experience with software, that secrecy is the enemy of quality — that software bugs, like cockroaches, shun light and flourish in darkness. So, too, with mistakes in the interpretation of scientific data; neither deliberate fraud nor inadvertent error can long survive the skeptical scrutiny of millions. The same remedy we have found in the open-source community applies – unsurprisingly, since we learned it from science in the first place. Abolish the secrecy, let in the sunlight.

QotD: “Genetics is interesting as an example of a science that overcame a diseased paradigm”

Filed under: Health, Media, Quotations, Science — Tags: , , , , — Nicholas @ 01:00

This side of the veil, instead of looking for the “gene for intelligence”, we try to find “polygenic scores”. Given a person’s entire genome, what function best predicts their intelligence? The most recent such effort uses over a thousand genes and is able to predict 10% of variability in educational attainment. This isn’t much, but it’s a heck of a lot better than anyone was able to do under the old “dozen genes” model, and it’s getting better every year in the way healthy paradigms are supposed to.

Genetics is interesting as an example of a science that overcame a diseased paradigm. For years, basically all candidate gene studies were fake. “How come we can’t find genes for anything?” was never as popular as “where’s my flying car?” as a symbol of how science never advances in the way we optimistically feel like it should. But it could have been.

And now it works. What lessons can we draw from this, for domains that still seem disappointing and intractable?

Turn-of-the-millennium behavioral genetics was intractable because it was more polycausal than anyone expected. Everything interesting was an excruciating interaction of a thousand different things. You had to know all those things to predict anything at all, so nobody predicted anything and all apparent predictions were fake.

Modern genetics is healthy and functional because it turns out that although genetics isn’t easy, it is simple. Yes, there are three billion base pairs in the human genome. But each of those base pairs is a nice, clean, discrete unit with one of four values. In a way, saying “everything has three billion possible causes” is a mercy; it’s placing an upper bound on how terrible genetics can be. The “secret” of genetics was that there was no “secret”. You just had to drop the optimistic assumption that there was any shortcut other than measuring all three billion different things, and get busy doing the measuring. The field was maximally perverse, but with enough advances in sequencing and computing, even the maximum possible level of perversity turned out to be within the limits of modern computing.

(This is an oversimplification: if it were really maximally perverse, chaos theory would be involved somehow. Maybe a better claim is that it hits the maximum perversity bound in one specific dimension)

What does an economist know about wine? Given that many wines need years to mature, how can one predict which ones will be great or not?

Princeton’s Orley Ashenfelter explains how he used economic principles and regression analysis to predict wine quality (and score great deals!). His research helped spawn an entire field dedicated to the economics of wine.

This video is based on the following paper:

QotD: Goodhart’s law

Filed under: Bureaucracy, Business, Economics, Quotations — Tags: , , , — Nicholas @ 01:00

This is why planning an economy simply doesn’t work. Issue targets that must be hit and people game the system to hit the targets without actually doing the desired underlying thing. Or, as it is formally constituted:

    Any observed statistical regularity will tend to collapse once pressure is placed upon it for control purposes.

Or as it has been reformulated:

    Goodhart’s law is an adage named after economist Charles Goodhart, which has been phrased by Marilyn Strathern as: “When a measure becomes a target, it ceases to be a good measure.” One way in which this can occur is individuals trying to anticipate the effect of a policy and then taking actions which alter its outcome.

Set a target for tonnes of shoes and you get one tonne shoes. Set a target for 100 shoes and you get 100 left feet. Set a target for being on time and people fiddle their definition of time.

It is, by the way, entirely fine to insist that airlines play fair with telling us how long a flight will take. You said it will take 4 hours, then 4 hours should be about the time it takes. Yes, sure, we understand, airports, crowded places. Idiot passengers forget to board, luggage must be taken off. Winds vary, thunderstorms happen, French air traffic controllers actually turn up to work today, their one day in seven. Sure, there’re lots of variables. But if you say it’s about four hours then it should be about four hours. Great.

But to complain that they pad their number a bit is ludicrous. We’re holding their feet to the fire, insisting that an underestimate will lead to financial costs. Thus, obviously, they will overestimate. That’s not really even Goodhart’s Law, that’s just human beings. But then, as we know, those who would plan everything don’t deal well with the existence of people, do they?

QotD: The statistical “Rule of Silicone Boobs”

Filed under: Health, Humour, Quotations, Science — Tags: , , , , — Nicholas @ 01:00

If it’s sexy, it’s probably fake.

“Sexy” means “likely to get published in the New York Times and/or get the researcher on a TEDx stage”. Actual sexiness research is not “sexy” because it keeps running into inconvenient results like that rich and high-status men in their forties and skinny women in their early twenties tend to find each other very sexy. The only way to make a result like that “sexy” is to blame it on the patriarchy, and most psychologist aren’t that far gone (yet).

[…]

Anything counterintuitive is also sexy, and (according to Rule 2) less likely to be true. So is anything novel that isn’t based on solid existing research. After all, the Times is the newspaper business, not in the truthspaper one.

Finding robust results is very hard, but getting sexy results published is very easy. Thus, sexy results generally lack robustness. I personally find a certain robustness quite sexy, but that attitude seems to have gone out of fashion since the Renaissance.

Misunderstanding what is meant by “mineral reserves”

Filed under: Economics, Environment — Tags: , , , — Nicholas @ 05:00

It seems to happen almost as regularly as Old Faithful, as someone blows a virtual gasket over the reserves of this or that mineral “running out” in x number of years. Tim Worstall explains why this is a silly misunderstanding of what the term “mineral reserves” actually means:

“Aerial view of a small mine near Mt Isa Queensland.” by denisbin is licensed under CC BY-ND 2.0

It’s not exactly unusual to see some environmental type running around screaming because mineral reserves are about to run out. The Club of Rome report, the EU’s “circular economy” ideas, Blueprint for Survival, they’re all based upon the idea that said reserves are going to run out.

They look at the usual listing (USGS, here) and note that at the current rate of usage reserves will run out in 30 to 50 years. Entirely correct they are too. It’s the next step which is such drivelling idiocy. For the claim then becomes that we will run out of those metals, those minerals, when the reserves do. This being idiot bollocks.

For a mineral reserve is, as best colloquial language can put it, the stuff we’ve prepared for use in the next few decades. Like, say, 30 to 50 years. That we’re going to run out of what we’ve got prepared isn’t a problem. For we’ve an entire industry, mining, whose job to to go prepare some more for us to use.

[…] A mineral reserve is something created by the mining company. Created by measuring, testing, test extracting and proving that the mineral can be processed, using current technology, at current prices, and produce a profit. Proving that this is not just dirt but is in fact ore.

Mineral reserves are things we humans make, not things that exist.
