Great moments in trend-setting

It's rare that I'm ahead of the curve in very much. But the latest Steve Sailer column had the following puzzling claim:
Nobody can deny Lindsay, Boghossian, and Pluckrose one historic accomplishment: They’ve permanently affixed the name Grievance Studies to their targets.
Before last fall, there were a variety of self-designations that only their smartest critics could keep track of. For example, Steven Pinker tweeted,
Is there any idea so outlandish that it won’t be published in a Critical/PoMo/Identity/‘Theory’ journal?
But if you aren’t quite up to Pinker’s level of brainpower, it’s hard to remember that “Critical/PoMo/Identity/‘Theory’” are all more or less the same moonshine.
But now we don’t need to. They are all just Grievance Studies.
Google searches show that the term “grievance studies” appeared only 85 times in the history of the internet before they announced their hoax last October, but 89,700 times since then.

To which my first thought was: huh? Hasn't everyone been using this term for ages?

No, it just turns out, I've been using it for ages. I couldn't get Sailer's "85 results" number easily. But this post of mine from May 2013 features the phrase. Though, hilariously, it doesn't seem to show up on my google search, and since I'm John Q. Nobody, read by nobody, I contributed almost zero to the currency of the phrase.

I have no idea if I just picked it up from someone else, or it independently seemed like a good description. To slightly paraphrase Moldbug, the great thing about the truth is that, being true, anybody is free to notice it at any time.

Come to Chateau Holmes for fresh social commentary, or be one of the herd reading about it at Sailer's blog six years later!

(I kid - Steve Sailer is a national treasure, and the best journalist of his generation. The fact that he writes for donations at the Unz Review, instead of having major newspapers fight to hire him, tells you everything you need to know about the clown world we live in).

On the eloquence of the ancients

One of the frequent complaints about modernity that both reactionaries and conservatives agree upon is the lamentable decline in the standards of public discourse. This is pretty clearly true, and you can show it in various different ways.

For instance, Thomas Jefferson spoke English, French, Italian, Latin, and could also read Spanish and Greek. The highly educated Barack Obama spoke... just English.

If you want a non-political example, consider Paul Fussell's observation about World War I poetry. Wilfred Owen, when writing his poem "Dulce et Decorum Est", could write as the ending lines to his famous poem, an untranslated Latin phrase from Horace, with confidence that his audience, which included privates in the army, would know what he meant.

Or, if you think I'm cherry-picking this, price-onomics computed the reading grade-level of the State of the Union address over time. If you plot it versus the starting year of the president's term, this is what you get:




Which, I will readily acknowledge, looks a lot like a slow descent into idiocracy.

And, to be fair, this is my depressing first order assessment of how the matter stands.

But, if I were to put a small positive spin on this, it would be the following.

Suppose that the level of reading education has declined precipitously. Conceptually, this could be because
i) The total amount of education has declined. 
ii) The efficiency per hour of education has declined. 
iii) The fraction of education devoted to reading has declined

Out of these, I'm pretty sure #1 isn't the case. We spend more time in school and college than ever. Not only that, but the biggest increase is probably among the least educated, who once upon a time would have gone straight into agricultural jobs, etc.

The second part I'd be willing to believe. We spend endless time on pozz and diversity propaganda, whereas back in the past they were probably drilled on the important stuff and didn't screw around.

But I think the biggest underappreciated factor is #3.

In particular, it's easy to forget just how enormous the increase in education was in quantitative disciplines. I suspect, but can't prove, that the fraction of people that are learning calculus, chemistry, and physics is a lot higher. In particular, without a calculator, a lot of these disciplines become much more labor intensive in terms of how many calculation examples you can give to illustrate a principle. 

There's an even more concrete example.

The field of statistics as we know it didn't really exist until Sir Francis Galton invented it in the mid-19th century. Don't believe me? He came up with standard deviation, correlation, regression, and regression to the mean. Try, if you will, to imagine what your statistics class would have been like before that. There's the mean, and...um... the mean?

And without these tools, think how many other discussions become impoverished.

Economics doesn't have any data without computers. But without regression and correlation, it doesn't have any meaningful way to discuss causation, or to resolve arguments with data (even if you were willing to do it by hand). Hence the whole discipline becomes only theory. And theory back then was largely essays. Economics didn't become mathematical until Von Neumann, Oskar Morgenstern and Paul Samuelson, all of whom did their major work after World War 2. Finance as a serious academic discipline didn't exist before Harry Markowitz, around the same time. And this is without discussing the disciplines that trivially didn't exist, like computer science, and those that only became formalised later, like psychology.

Take out all of the high school and college education devoted to these subjects, and ask yourself - what's left to do other than read the classics and learn languages? Not only this, if you could erase all your knowledge of the above subjects and replace it with more eloquence and knowledge of the classics...would you? Would the bargain seem worth it?

To me, it's not obvious at all.  

As I wrote about a while ago - expressions of a desire to do some self-improvement task are pretty much like a politician's unfunded campaign promises. That is, unless you specify exactly what in your week it is you're willing to give up in order to make it happen, it's not actually a serious plan. And just like in politics, the two standard answers are both bad. I'll get rid of waste and duplication! In your life, like in politics, there is assuredly waste and duplication, but it's similarly assured that you probably won't get rid of it. Or you'll just run a budget deficit by sleeping less. Which works in the long run about as well as you'd expect.

So it is with the importance of a classical education. It doesn't mean you shouldn't do it. It just means that simply cutting out the modern leftist propaganda from the curriculum won't turn you into Jefferson. You've got to cut much closer to the bone, into subjects that actually do matter.

The other lesson, of course, is that Sir Francis Galton was a god damn genius, and is criminally underappreciated. It's hard to imagine the social sciences existing without him.

How to Break the College Monopoly on Credentials

Suppose you were to think, like me, that America suffers from a significant surplus of university education. It takes young men and women, ladens them with hundreds of thousands of dollars of debt, and indoctrinates them with progressive propaganda in an atmosphere of hedonism for four years.

On its own, this is bad enough. But instead, a bizarre idea has developed that everyone needs a college degree in order to be a person of any worth. Which means that the above process now applies to a far greater fraction of the population than it did two generations ago. And the new people at the margin, going to crummy colleges, are likely to be those for whom the instructional value is of the least benefit.

As far as I can tell, the massive increase in demand for higher education over the previous decades seems to be cargo cult reasoning writ large - rich successful people went to college, ergo if I go to college I will be rich and successful. A fortiori, if we all go to college, we'll all end up rich! Better subsidize all those student loans, now helpfully made non-dischargeable in bankruptcy.

The unfortunate part is that I suspect that a good number of the people who go to college (or at least their parents) probably sympathise with the fact that the above reasoning is moronic. So how come they don't just skip it? Because, of course, it's a signalling arms race. Nobody ever got fired for buying IBM, and nobody ever got fired for hiring the Harvard undergrad. 

Surely, you may think, there must be enough people who see through this, and realise that intelligent people willing to spend the four years doing on-the-job training will end up much better skilled than those who just graduated from college? Wouldn't they be willing to punt on these people, and thereby put an end to much of the madness?

The problem, of course, is information asymmetry. The enormous college application system acts as a certification system of hopefully job-related traits, mixed in with pozz, affirmative action, and associated nonsense. But it is quite adept at producing one conclusion: if you go to a university ranked between #15 and #25, it is highly probable that you applied to, and got rejected from, universities ranked #1 through #14. What you actually learned in the college is harder to assess. There's some value in GPA, but that keeps getting grade inflated more and more.

And getting an equivalently good signal elsewhere is still quite difficult, which I suspect is why employers skeptical of the quality of instruction at colleges still use it. The Supreme Court has made IQ tests effectively prohibited in hiring decisions unless you're willing to risk ruinous disparate impact lawsuits, and the general mix of extra-curricular activities, essays, and in-person interviews that signals "high achieving and socially adept" is easier to outsource to universities than to do in-house for most companies.

So if employers rely on this signal, if you don't go to college, you get lumped in with the people who couldn't get into any college at all. Obviously, in person it's not hard to signal that you're smarter than the rest of that pool. But how do you get past the first HR screening? How do you avoid people just assuming that you didn't go to college simply because you couldn't go to college, or at least any one worth attending?

Well, one way you could deal with it is as follows. Work very hard in high school, and apply to all the best colleges. Then take your best five acceptance letters, staple them to your CV, but don't go to any of them. This is something that people wouldn't quite know what to make of. They have a category for people who couldn't get into college. They have a category for "college dropout", as someone who got into a good college, but (they assume) having got there was too lazy, too much of a misfit, or just unable to hack it. But they have no category for someone who got into a good school but never went in the first place. Which means they have to think a bit harder as to what to make of you. If you turn up with an acceptance from Stanford, and a glowing high school record, and that's the last data on the subject because you never actually turned up, it's much harder for employees to put you in the dropout category, as the last data on the subject indicates that you probably would have succeeded. The reason this works is that college has largely become a joke, whereby it's very hard to actually fail out. Getting in may be hard, but getting through is not. The more of a joke it becomes, the more viable becomes the strategy of just signalling that you got accepted.

If you include with your CV a brief letter explaining how you think that college is a very expensive, bad deal for most students, and you'd much rather spend the time earning money and acquiring useful on the job skills, lots of employers would probably agree. Moreover, if you've already credibly shown that you could have done it, much of the signalling value is already achieved. Most of the signal is getting accepted, but it doesn't cost $100K for an acceptance letter. It's still possible that idiot HR types that just mechanically screen on college degrees (though you wouldn't fit into a clean bucket, so they may have to ponder harder what to do with you). The other risk is that people will just assume you're weird, simply because this is an unorthodox choice to make. I think this is where it's particularly important to come across as reasonable, thoughtful and socially skillful in your explanatory letter, so that employers don't think that you didn't go just because you were too much a weirdo.

I suspect if this got going (particularly if people realised that you could actually get hired this way), the monopoly on "you have to go to college" might unravel quite quickly. At a minimum, if you're planning on not going to college, this is a pretty low cost exercise to go through with almost no downside. It almost certainly will make you look more appealing to the employers of the world for much less than the cost of a college degree.

How to Improve the Discourse on Education Policy

Is there a subject of policy debate in modern society more deranged than education? When it comes to primary and secondary education, the sheer sentimentality, mendacity and surreality of most policy proposals borders on incredible. We just need to Fix The Schools™, then everything will be alright with our wayward youth.

Education, curiously, is one of those subjects on which the divide between the reactionary mindset and the mainstream conservative mindset is starkest.

As far as I can tell, there seem to be three main explanations for why some schools perform poorly.

The leftist mindset is that the problem with "bad schools" (where this is usually taken to mean "schools with poor measures of student academic achievement) is a lack of resources. School funding is tied to property taxes, so rich schools get more money than poor ones, and that's why they perform better. More money will let them buy textbooks, and ipads, and hire better teachers, and have art programs which will distract kids from joining violent gangs, etc.

Of course, this runs up against the problem that we've been throwing money into education, hand over fist, for decades, with literally nothing to show for it. As Scott Alexander discussed a few weeks ago in his post on cost disease:



Maybe another 50% increase and we'll finally Fix The Schools™!

And then there's the mainstream conservative answer: the problem with bad schools is bad teachers and bad incentives. The teachers unions are powerful, and the Democrats are beholden to them, which means that there's no competition across schools, no ability to fire underperforming teachers, no incentives for better performance etc.

This of course runs into the problem that if this were the main driver of educational differences, then states where the Democrats have strong political power should do worse. Do they?

No. If you take, say 2015 NAEP 8th Grade Mathematics Scores (available here) and correlate them with 2016 Democratic Presidential Vote Shares (available here), you get a whopping correlation of  -0.0595. If you're a regression guy, if you regress mathematics test scores on vote percentage, the t-stat is a paltry -0.417, with an R-squared of 0.0035. 

But even this overstates the case, because DC is a huge outlier in vote share at 90.48%, and an absolute sinkhole in terms of test scores. If you take DC out, the correlation is actually positive, at 0.183 (though the t-stat on the regression is still insignificant, at 1.29). If you use 2012 vote shares, which were perhaps more usual, the correlation increases to 0.214 excluding DC, and the t-stat is 1.52. That is to say, more Democratic states do, if anything, slightly better, though the effect isn't particularly strong. You can see this just by ranking the states:

State NAEP Math Dem. Vote Share

West Virginia 271 26.48%
Louisiana 268 38.45%
Alabama 267 34.36%
District of Columbia 263 90.48%

Admittedly there's a lot more variables you'd want to throw into the regression, but still, the univariate big picture doesn't look like the Republican story either.

So what's the reactionary position on why there are bad schools? 

Bad schools are primarily due to bad students. Some students are dumb, unruly, lazy, dysfunctional brats. They can't learn, won't learn, and don't learn. You don't even need to take a strong stance on why these differences arise, but just assume that by the time the kids arrive at school, some of them are just a drain and a menace on everyone around them.

And for some reason, this explanation is considered anathema to most right-thinking people. How can you say anything so mean? All students have the potential to succeed, if only they're given the right circumstances!

If the reactionary position strikes you as excessively unkind (especially if its unkindness makes you flinch from accepting its possible truth), I want you to try the following thought experiment.

When you think of "schools", what mental picture comes to mind?

I suspect you are thinking of an idealised brochure, a smiling child at a desk, something that would fit easily as an advertisement for a charity on the side of a bus. The kid is also likely to be young, probably around 5-8 years old, bright-eyed at the world.

Stop thinking of that. Schools aren't like that.

Okay, so what are schools like? 

You don't need me to tell you. You've been to one. 

To borrow an idea from the War Nerd (when he was explaining why it was easy to get young men to fight and die in wars): if you want to think of schools, think of your 9th grade PE class.

Who was in that class? There were some good students, some of your friends that you think fondly of. If you're reading this blog, chances are both you and your friends were pretty high achieving.

Then there were some middle of the road kids, who were nice enough, and filled out the fat part of the bell curve.

Then there was almost certainly a solid rump of kids best described as complete dickheads. Dumb, mean, idiots. That bully who liked to pick on the young kids. That big punk who stole your friend's bike tire. That guy who was thick as two planks, and boasted about taking a crap on some stranger's car while drunk one Saturday night.

Now, think of just those scumbags, because these are almost certainly the underperforming students we're trying to fix. Imagine that you're designing education policy. How can you improve the educational outcomes of those students? Are they suddenly going to apply themselves more if higher property taxes provide them with a free iPad? Are they about to dive into calculus if only they can find some inspiring young teacher with hip and fresh real world examples of differential equations?

Of course they're not. They're just idiots who will make life miserable for whoever is around them. 

If your school has too many such students, it is probably going to be a "bad school". Now, at this stage of argumentation, it is still a matter of conjecture that the scumbag kids of the world are not spread exactly uniformly across every single school district. But is the idea so outlandish? Do you think the adult scumbags are spread precisely uniformly across every neighbourhood and state? Perhaps this matches your experience of traveling around your city or country, but somehow I doubt it. If it were true, you should feel approximately equally happy moving to any neighbourhood in your city, or any state in the country, since everyone is basically the same! Yeah right. And if the annoying adults aren't distributed uniformly, why should the kids be? The first law of behavioral genetics doesn't go away just because you're feeling sentimental about all kids being nice at heart. And given the capacity of nasty kids to have enormous disruptive negative spillovers on the kids around them, it's not clear how much of a difference in distribution you would need to affect the aggregate outcomes. 

But even if you think of the whole distribution of students (rather than just the left tail), did that distribution seem like something pretty fixed over your schooling, or something with a lot of year-to-year variation? Did the students in the bottom third of the class in one year ever suddenly jump to the top third the next year as a result of a really good teacher? Or would you say that the personal traits, and relative test scores, of the students in your class were approximately stable in rank order over your whole school career? How confident are you that your treatment could upset last year's rank order by very much?

If your education policy doesn't seem like it will work on the ne'er-do-well kids in your 9th grade PE class, it's probably not going to work at all.

And thinking about those kids is an incredibly grounding reality check to cure multi-billion dollar sentimental nonsense that every kid is just wanting to get the best possible education in life. Some are. Some aren't. It's not that every child who does badly at school is also mean and of poor character. But thinking about the ones that are is the best cure for hazy, rose-tinted thinking on the subject. It makes it easier to focus on the sheer stubbornness of the problem at hand.

None of this means that the reactionary position is the only difference across schools, or that there isn't any role for other factors. But let's just say that it's a hypothesis that seems like it might be worth considering more than currently is done, at least in the public discourse.

It is self-evident that the world has a substantial fraction of dickheads in it.

All of those dickheads were 10 years old once. 

Most of them were probably dickheads back then too.

Why school group work sucks

If you, like me, were a nerdy type-A personality at school, you probably loathed getting put into groups for assignments. Inevitably, you'd be stuck with some bunch of lazy idiots who could credibly commit to either:
a) not caring if they got a terrible grade, and hence being uninterested in working, or
b) not being capable of getting a good grade even if they did work.

Both of these would get you to the most common outcome - the smart kid does all the work, usually ostentatiously announcing beforehand that the dumb kid is going to screw it up and thus insisting that he leave it alone, all the while still resenting the dumb kid for his idleness. The dumb kid laughs at the smart conscientious kid slaving away like a sucker.

Teachers would always spin you a bunch of junk about this being useful preparation for the real world, and how it was important for you to learn to work with people you didn't necessarily pick.

Looking back now, I realise that this was all a crock of crap - school group assignments prepare you for nothing useful, and all the irritation you felt was in fact completely justified.

The standard complaint is that you're being allocated into groups you didn't pick, and with hugely varying levels of skill. Neither of these really describes the real world. You get to pick the company you work for, even if you don't get to choose who is on every project with you. That said, it's highly unlikely that any semi-competent manager would lump together one guy who knows what he's doing and a bunch of morons who don't. Hopefully, there's a minimum level of competence required to maintain gainful employment, and you're unlikely to be stuck with someone truly awful.

That said though, it's become increasingly obvious that this isn't the real problem that makes school projects uniquely worse than real-life group projects.

No, the real problem with school projects is the following:

Everyone has accountability, but nobody has authority.

In other words, everyone is responsible for the performance of the group, but nobody has the authority to actually order anyone to do anything. If someone does a bad job, or hands things in late, or generally is so clueless that you'd rather do it yourself, there's not much you can do. If it gets really bad, you can complain to the teacher. But they generally don't want to deal with your whinging.

The assumption is that general social sanction for shirking, combined with the fact that everyone needs to work together to get the marks, should be enough to make it work. But isn't it obvious that setting up a mini-communist state for mark allocation is always going to produce a free-rider problem? And that the equilibrium is going to be that the guy who cares about it more does all the work?

This is like some Frankenstein version of real world group tasks. In most corporate settings, you're going to have a boss or team leader who is directly responsible for the team's performance, and can order people to do certain things on pain of getting fired. Hand the report in on Friday at 12pm or you get canned. Simple enough. Your boss may be an idiot, in which case it's a huge pain (of a very different sort). But at least there is a single person with the incentives to see the group succeed, and the authority to make it happen and solve the co-ordination problem.

If people get to pick their own groups and there's multiple assignments, the repeated game aspect can deter shirking somewhat.

But in general, teachers create a horrible system for assignments that simply teaches smart kids that the world is full of moochers, and that you'll end up doing a disproportionate share of the work only to see some slacker enjoy the fruits of your labour.

You might argue that this lesson is crucial for teaching them about the operation of the tax system and pork-barrel public-sector employment, and I wouldn't necessarily disagree.

I'd like to think that this was the well-thought-out plan all along, but somehow I doubt it. The only way to fund these taxes is to have businesses whose internal team dynamics are so different that productivity results and there's a surplus to be stolen in the first place.
