Howard Gardner has also convinced us that the word intelligence carries with it undue affect and political baggage. It is still a useful word, but we shall subsequently employ the more neutral term cognitive ability as often as possible to refer to the concept that we have hitherto called intelligence, just as we will use IQ as a generic synonym for intelligence test score. Since cognitive ability is an uneuphonious phrase, we lapse often so as to make the text readable. But at least we hope that it will help you think of intelligence as just a noun, not an accolade.
We have said that we will be drawing most heavily on data from the classical tradition. That implies that we also accept certain conclusions undergirding that tradition. To draw the strands of our perspective together and to set the stage for the rest of the book, let us set them down explicitly. Here are six conclusions regarding tests of cognitive ability, drawn from the classical tradition, that are by now beyond significant technical dispute:
- There is such a thing as a general factor of cognitive ability on which human beings differ.
- All standardized tests of academic aptitude or achievement measure this general factor to some degree, but IQ tests expressly designed for that purpose measure it most accurately.
- IQ scores match, to a first degree, whatever it is that people mean when they use the word intelligent or smart in ordinary language.
- IQ scores are stable, although not perfectly so, over much of a person’s life.
- Properly administered IQ tests are not demonstrably biased against social, economic, ethnic, or racial groups.
- Cognitive ability is substantially heritable, apparently no less than 40 percent and no more than 80 percent.

“Raise our taxes!” cried the hypocritical virtue signallers
We’ve been over this ground before. Some very rich people are getting fawning media coverage for their “selfless”, “virtuous” demand that the government raise their taxes. Except they’re far from selfless: they’re demanding that other people be forced to pay more tax, but they’re very much not putting their own money where their bleating mouths are. Most governments are happy to accept more money from you than your formal tax liabilities:
- The Canadian federal government
- The British government
- The US federal government
- The province of Ontario
- The City of Toronto
… are all very eager to accept your contributions. But most people don’t take advantage of this mechanism, especially the ones garnering headlines for their “altruism”. Because they’re virtue signalling, and almost certainly don’t actually want to be taxed more. Don’t believe what people merely say they want, watch what they actually do (economists call this “revealed preference“). Hypocrites, the lot of them.
Router Plane Q&A | Paul Sellers
Paul Sellers
Published on 26 Jun 2019The router plane remains one of the most essential tools for hand tool woodworkers. It is used to refine cuts which are either made by chisels, saws or machines, Paul often even uses a router plane as an improvised marking gauge. In this Q&A Paul answers some of your questions regarding this remarkable tool.
Questions:
0:59 What wood do you recommend for making an extension plate for the base of the router plane? How thick should it be?
2:55 Recently the floor of some elements I have chopped have been deeper than my Stanley router reaches. Is there a way to extend the depth reach?
4:14 Having just bought my first router plane I was wondering what basic maintenance should I do to restore it to a good working tool?
5:17 What is the best way to set the height to make sure you don’t plane too deeply?
7:11 Do you recommend attaching a wooden support screwed to the base of the plane?
7:54 My Veritas router plane changes depth during the cut (the shank of the iron slips in the collar). Is there a trick that will prevent this slippage and help ensure an equal depth across the entire surface?
10:11 How does one prevent tear out when routing?
12:11 One thing I’ve noticed by watching your videos is that you only use the router plane to put the finishing touches on tenon cheeks, dados and the like. Was the router plane designed for more than this or is this where the router shines?
15:04 Grain issues? Cutting out a channel/tenon, I often ‘dig in’ (no, not taking big cuts), likely due to grain? You’ve mentioned ‘feeling’ for grain with No4 plane, how do you address this with the router plane?
18:05 The main issue I have when using a router is that the shavings end up between the sole of the plane and my workpiece. These shavings scar the wood of my workpiece. How to prevent this? Or is this to do with the router plane itself?
21:40 Is the router plane effective for making a groove with the width of the iron or a rebate, as you do with the plough plane?
23:55 Is it important to get a router plane with the micro adjustment height wheel for that extra precision, or will a model without the adjustment wheel do the job just fine?
26:02 Are there specific times when you would reach for a router plane over a plough plane (and vice versa) when either could seemingly be used?
27:49 Diamond point vs square blade
28:46 How to prepare the wood for the sole?The featured Paul Sellers book is available to order from anywhere in the world. Click the link to find out more: https://paulsellers.com/paul-sellers-…

$26B, $56B, $70B, and pretty soon you’re talking real money
The headline refers to the constant upward movement of various estimates on how much the Canadian government will be required to spend on the Canadian Surface Combatant program. In shorthand, that’s the money required to replace the Royal Canadian Navy’s current fleet of 12 frigates and the Iroquois-class destroyers that have already been retired from service. The Halifax-class frigates began entering service in the early 1990s and were designed to operate for about thirty years, meaning the RCN needs replacements to start coming into the fleet in the mid-2020s. The government initially budgeted around $26B for fifteen ships in 2008, but as with so many military equipment programs, no actual steel has been cut to begin building the new ships … in fact the design was only formally agreed in October 2018 and not signed (due to a lawsuit from one of the losing bidders) until February of this year. We’re still probably 2-3 years away from construction of the first ship in the class beginning, which will mean the Halifax class will have to remain on duty for longer (and older ships require more frequent and more expensive maintenance).
The Department of National Defence most recently estimated up to a $60B final bill, but the Parliamentary Budget Office estimate was $70B (an increase of $8B over a two-year span), and there’s no reason to assume that things will magically get cheaper between now and whenever Irving Shipbuilding starts construction of the first new ship. David Pugliese reports:
… it could be years before the real cost to taxpayers for the mega-project is actually known as the project is just getting started.
The PBO report warned that any delays in building the first ship will be costly. A delay of one year, for instance, could increase costs by almost $2.2 billion, it added.
The federal government hopes to begin building the ships starting in the early 2020s.
Pat Finn, the head of procurement at DND, said the PBO estimates largely align with what the department figures as the cost of the program. He noted that unlike the PBO, the department does not consider tax in its cost figures. That is because those fees ultimately go back to the federal treasury.
But he also agreed with the PBO on the concern about added cost if the project is delayed. “That is a key one for us. It’s something we’re watching carefully,” said Finn, assistant deputy minister for materiel.
The CSC program is currently in the development phase. The government projects the acquisition phase to begin in the early 2020s with deliveries to begin in the mid-2020s. The delivery of the 15th ship, slated for the late 2040s, will mark the end of that project.
The Liberal government announced in February that it had entered into a contract with Irving Shipbuilding to acquire new warships based on the Type 26 design being built in the United Kingdom. With Canada ordering 15 of the warships, the Royal Canadian Navy will be the number one user of the Type 26 in the world.
The United Kingdom had planned to buy 13 of the ships but cut that down to eight. Australia plans to buy nine of the vessels designed by BAE of the United Kingdom.
The entry of the BAE Type 26 warship in the Canadian competition was controversial from the start and sparked complaints the procurement process was skewed to favour that vessel. Previously the Liberal government had said only mature existing designs or designs of ships already in service with other navies would be accepted, on the grounds they could be built faster and would be less risky. Unproven designs can face challenges as problems are found once the vessel is in the water and operating.
But the requirement for a mature design was changed and the government and Irving accepted the BAE design, though at the time it existed only on the drawing board. Construction began on the first Type 26 frigate in the summer of 2017 for Britain’s Royal Navy, but it has not yet been completed. Company claims about what the Type 26 ship can do, including how fast it can go, are based on simulations or projections.
Ted Campbell commented on the report:
I’m not sure the new ($70 Billion) figure is a terribly useful number for taxpayers like you or me or for policymakers, either. I’m not convinced that DND, itself, much less the whole of government, including the PBO, has a common, coherent understanding of “life-cycle costs,” and I’m damned sure neither the media nor 99.99% of Canadians has one. I’m glad to see that the government includes “the cost of project development, production of the ships, two years of spare parts and ammunition, training, government program management, upgrades to existing facilities, and applicable taxes” but that’s just the tip of the iceberg. These ships are going to be in service for 35± years and they are going to cost money to own and operate every hour of every day and I hope someone is programming ongoing costs (running costs, routine maintenance, upgrades and refits and life extension projects and even disposal) into the long term defence budget guesstimates.
Good management says that the DND budget should be pretty well fixed for the next year or two, fairly firm (even allowing for a change in government) for four or five years beyond the end of the next fiscal year it should be and a reliable planning guide for the next decade or even two. In other words, DND should have a pretty good idea about what it will cost to operate itself, pretty much as it is now, for a generation. I expect (hope, anyway) that defence planners have a “Christmas wish list” of capabilities they want to add or improve/increase (with costs attached) should a defence friendly government ever materialize in Canada or, sadly but more likely when, not if, the need arises.
He also points out the hidden truism about huge government purchases:
… from 1950 to 1958 the several hundred Canadair F-86 Sabre jets that Canada bought for the RCAF was, probably, “the largest single expenditure in Canadian government history,” then from the early 1950s until 1964 the production of 20 destroyers (DDE and DDH) of the St Laurent, Restigouche, Mackenzie and Annapolis classes (all based on one, baseline, design) was, almost certainly, “the largest single expenditure in Canadian government history,” and I know for a fact that the purchase decision (in 1980) of 138 CF-18 Hornets made it “the largest single expenditure in Canadian government history.” The simple fact is that the costs of high-tech aircraft, howitzers, tanks, radios and, especially, ships, keep climbing far faster than inflation and if, as we must, we want our armed forces to be adequately equipped then we need to accept higher costs … especially if we want to build ships in Canadian yards, employing Canadian workers.

“… what’s happening now is even better than Apollo”
At Popular Mechanics, Joe Pappalardo reminds us that the 50th anniversary of the Apollo 11 lunar landing is coming up next month, but that current developments in space are worth celebrating too:
Apollo was born of Cold War desperation: a political exercise that paid enormous scientific and technological dividends. After the launch of Sputnik in 1957, it became vital to beat the Soviet Union to the Moon, a geopolitical urge that created an enormous budgetary effort.
The problem with politically motivated — well, anything — is that the faucet of support can be closed just as quickly as it opened. It happened to Apollo, as follow on missions were cancelled and the focus shifted to a reusable craft to service low-earth orbit. This pattern of shifting space priorities and strategies whipsawed NASA, most noticeably when the Obama administration’s cancellation of the Bush-era Constellation moon program in 2010.
But multiple private companies pursuing their niches in space have an obvious redundancy. While companies may rise and fall, the very nature of a commercial effort isn’t as dependent on government funding. If it’s worth doing, especially if it makes money, space industry will endure political shifts. The objectives of a well-run company do not change that much every four years.
That leaves today’s NASA with a choice: Do it themselves and control everything (the traditional way), or fund private companies to develop the tech the agency needs and then allow them to sell their services to any nation, company, or individual (the new way). With those services on the open market, NASA would be one of many customers for a new U.S.-based space economy.
This debate is boiling over right now. The ongoing effort to return to the moon, called Artemis (after Apollo’s sister), is becoming a lesson in the advantages of the commercial model.
[…]
If only investment guaranteed results. For those who miss bloated, government-run spaceflight, there is already a NASA spacecraft mired in the old ways of thinking. The feds have sunk a lot of money into the Space Launch System, a mega-rocket built to NASA specs for deep space missions. It was supposed to fly in 2017, but we’ll be lucky to see a first flight in 2020 — and it busted the $9.7 billion estimated budget, now costing about $12 billion.
But something happened during these SLS delays: the commercial space industry started delivering on its promises. Most visibly, private firms have been delivering supplies to the International Space Station for years and (hopefully soon) will ferry astronauts as well. Blue Origin and SpaceX has started development of crewed spacecraft able to reach to the moon and Mars. Elon Musk even sold a moon trip to a Japanese billionaire.

What is the problem that a wealth tax is designed to solve?
Andrew Coyne asks the obvious question about the sudden keen interest in imposing wealth taxes:
It is noteworthy how the debate on inequality has shifted in recent years: from the problem of poverty, whose evils are obvious, to the “problem” of great wealth; from the gap between the poor and the rest of us, to the gap between the rest of us and the rich, or indeed between the rich and the very rich.
But it is not obvious why it is wrong, in itself, that a small number of people should get stinking rich. It is clearly objectionable if they did so by illicit or unethical means — but then it is the means itself, not the wealth, to which we object. And it would be in poor taste, at the least, if they spent it all on themselves. But that is not how the great fortunes are typically disposed of — it’s physically impossible to spend more than a small fraction of it.
Perhaps the argument is less that the rich are too rich than it is that the government is too poor. You can make a case that government should spend more on certain things, especially in America. It doesn’t follow that you need to raise taxes to do so. A lot of good new spending could be funded by cutting bad old spending.
Suppose there were a case for raising taxes. Are wealth taxes the way to go? Wealth is, after all, merely the accumulation of past income — and we already tax income. If rich people are exploiting loopholes to avoid paying tax on their incomes, by all means close the loopholes. But the case for taxing income twice seems obscure.
Yes, we already have a kind of wealth tax, in the form of municipal property taxes — and they’re a notorious mess. They conform to none of the usual principles of good taxation, being neither simple, nor efficient, nor fair.
Why unfair? The bedrock criteria of tax fairness is supposed to be ability to pay. That’s only uncertainly related to wealth. Suppose the value of your house shoots up. Congrats: suddenly you’re wealthy. But your income is unchanged. And it’s income you need, or more accurately cash, to pay your taxes. It’s not clear why you should pay more in tax than someone with the same income, but a cheaper house.

QotD: “Right-wing central planning is as foolish as left-wing central planning”
It is the old familiar dream of the central planner, an orrery economic universe in which things move in predictable and comprehensible patterns. That model of the economy has no relationship to reality. A million different things might become of any given laid-off steelworker; predicting what would happen to an entire industry’s work force (or even a small portion of it) in the absence of a certain protectionist policy is not economics — it is speculative fiction. For the most part, we do not have a very good record for predicting the effects of policies; trying to build a set of policies on an intellectual framework consisting of imagined counterfactuals will fail for the same reason that wage and price controls fail, agricultural-market management fails, and those highly targeted “investments” every president proposes in every State of the Union address fail: Human civilization is not an ant farm that can be viewed in cross-section and comprehended in total.
The real world is populated by politicians and lobbyists rather than philosopher-kings, but a government of philosopher-kings that tried to micromanage the economy in the way Beattie suggests would fail, just as all similar attempts at putting the economy under political discipline have failed. Right-wing central planning is as foolish as left-wing central planning.

Barbara Kay on the rise of Maxime Bernier’s People’s Party of Canada
In The Post Millennial, Barbara Kay explains why there may be a good opportunity for Maxime Bernier to attract votes from disaffected Canadians who don’t feel the other parties represent their interests and concerns:
The nationalist Brexit Party, led by outspoken euroskeptic Nigel Farage, came into existence last January. Four months later, it boasts 29 MEPs (Members of the European Parliament). By contrast, this past May, Canada’s Green Party elected its second member of parliament after 36 years of existence.
There’s a message here. The Green Party is not a “disruptor” of the status quo, and it doesn’t represent a groundswell of voices who feel left out of the conversation. It’s just a more fibrously left wing form of the same political granola served up by the NDP and the Liberal Party. It’s not really needed. But the Brexit Party’s success is a genuinely organic statement of anger directed at traditional parties by great swaths of citizens who not only felt disrespected and ignored, they actually were, by any objective standards, disrespected and ignored. It was needed.
Forty percent of Canadians routinely choose not to vote. A certain number are politically indifferent, but another number don’t vote because they don’t feel any of the parties represent their views. Normally, they don’t feel worried enough to bestir themselves. Will the pattern hold in October?
Or is this Maxime Bernier’s “disruptor” moment? His People’s Party of Canada was officially launched in January, and it presently has more members than the Green Party. The PPC is fielding candidates in all 338 ridings, an impressive accomplishment given the time constraints. Their basic platform, which includes tax simplification, the abolition of supply management, as well as long-overdue abolition of inter-provincial tariffs, indicates commitment to fundamental conservative principles.
But those issues speak to the mind, not the heart, and a slew of anxious Canadian hearts are what is presently up for grabs. One of Bernier’s great strengths is that in spite of years of political experience, he has not become jaded or cynical. He wears his own heart on his sleeve. Not a thespian, mantra-driven, lachrymose, pre-programmed “heart” of the kind Trudeau is so famous for, but an unsentimental heart full of deeply-considered convictions that beat, like ruggedly-manned boats, against the progressive current upon which Justin Trudeau is a dreamily bobbing twiglet.
One of those convictions is that chronic breast-beating about the sins of the past and suppression of pride in Canadians’ national identity is creating an unhealthy social and cultural environment, dominated by grievance-mongering special-interest activism that corrodes national confidence and unity of purpose.
Another related, perhaps pivotal strength is Bernier’s passion for freedom of speech.
