Book review: Seasteading, by Joe Quirk, with Patri Friedman.

Seasteading is an interesting idea. Alas, Quirk’s approach is not quirky enough to do justice to the unusual advantages of seasteading.

The book’s style is too much like a newspaper. Rather than focus on the main advantages of seasteading, it focuses on the concerns of the average person, and on how seasteading might affect them. It quotes interesting people extensively, while being vague about whether the authors are just reporting that those people have ideas, or whether the authors have checked that the ideas are correct. Many of the ideas seem rather fishy.

I suspect that seasteading’s biggest need now is businessmen and/or VCs who can start cruise-ship-sized projects. Yet the book seems aimed more at creating broad, shallow support among ordinary readers than it is at inspiring competent entrepreneurs.

Peak Fossil Fuel

This post is about the combined effects of cheap solar energy, batteries, and robocars.

Peak oil is coming soon, and will be at least as important as peak whale oil; probably more like peak horse.

First I noticed a good article on the future of fossil fuels by Colby Davis. Then I noticed a report on robocars by Rethinkx, which has some fairly strong arguments that Colby underestimates the speed of change. In particular, Colby describes “reasonable assumptions” as implying “Electric vehicles would make up a third of the market by 2035 and half by 2040”, whereas RethinkX convinced me to expect a 2035 market share of more like 99%.

tl;dr: electric robocars run by Uber-like companies will be cheap enough that you’ll have trouble giving away a car bought today. Uber’s prices will be less than your obsolete car’s costs of fuel, maintainance, and insurance.

As I was writing this post, a Chinese official talked about banning gas-based cars “in the near future” (timing not yet decided). If only I had bought shares in a lithium mining company before that news.

Solar costs have dropped at a Moore’s law-like rate. See Swanson’s law.

In this post, I’ll describe features of the moral system that I use. I expect that it’s similar enough to Robin Hanson’s views I’ll use his name dealism to describe it, but I haven’t seen a well-organized description of dealism. (See a partial description here).

It’s also pretty similar to the system that Drescher described in Good and Real, combined with Anna Salamon’s description of causal models for Newcomb’s problem (which describes how to replace Drescher’s confused notion of “subjunctive relations” with a causal model). Good and Real eloquently describes why people should want to follow dealist-like moral system; my post will be easier to understand if you understand Good and Real.

The most similar mainstream system is contractarianism. Dealism applies to a broader set of agents, and depends less on the initial conditions. I haven’t read enough about contractarianism to decide whether dealism is a special type of contractarianism or whether it should be classified as something separate. Gauthier’s writings look possibly relevant, but I haven’t found time to read them.

Scott Aaronson’s eigenmorality also overlaps a good deal with dealism, and is maybe a bit easier to understand.

Under dealism, morality consists of rules / agreements / deals, especially those that can be universalized. We become more civilized as we coordinate better to produce more cooperative deals. I’m being somewhat ambiguous about what “deal” and “universalized” mean, but those ambiguities don’t seem important to the major disagreements over moral systems, and I want to focus in this post on high-level disagreements.

[Another underwhelming book; I promise to get out of the habit of posting only book reviews Real Soon Now.]

Book review: Seeing like a State: How Certain Schemes to Improve the Human Condition Have Failed, by James C. Scott.

Scott begins with a history of the tension between the desire for legibility versus the desire for local control. E.g. central governments wanted to know how much they could tax peasants without causing famine or revolt. Yet even in the optimistic case where they got an honest tax collector to report how many bushels of grain John produced, they had problems due to John’s village having an idiosyncratic meaning of “bushel” that the tax collector couldn’t easily translate to something the central government knew. And it was hard to keep track of whether John had paid the tax, since the central government didn’t understand how the villagers distinguished that John from the John who lived a mile away.

So governments that wanted to grow imposed lots of standards on people. That sometimes helped peasants by making their taxes fairer and more predictable, but often trampled over local arrangements that had worked well (especially complex land use agreements).

I found that part of the book to be a fairly nice explanation of why an important set of conflicts was nearly inevitable. Scott gives a relatively balanced view of how increased legibility had both good and bad effects (more efficient taxation, diseases tracked better, Nazis found more Jews, etc.).

Then Scott becomes more repetitive and one-sided when describing high modernism, which carried the desire for legibility to a revolutionary, authoritarian extreme (especially between 1920 and 1960). I didn’t want 250 pages of evidence that Soviet style central planning was often destructive. Maybe that conclusion wasn’t obvious to enough people when Scott started writing the book, but it was painfully obvious by the time the book was published.

Scott’s complaints resemble the Hayekian side of the socialist calculation debate, except that Scott frames in terms that minimize associations with socialism and capitalism. E.g. he manages to include Taylorist factory management in his cluster of bad ideas.

It’s interesting to compare Fukuyama’s description of Tanzania with Scott’s description. They both agree that villagization (Scott’s focus) was a disaster. Scott leaves readers with the impression that villagization was the most important policy, whereas Fukuyama only devotes one paragraph to it, and gives the impression that the overall effects of Tanzania’s legibility-increasing moves were beneficial (mainly via a common language causing more cooperation). Neither author provides a balanced view (but then they were both drawing attention to neglected aspects of history, not trying to provide a complete picture).

My advice: read the SlateStarCodex review, don’t read the whole book.

Book review: State, Economy, and the Great Divergence: Great Britain and China, 1680s – 1850s, by Peer Vries.

Yet another book on why Britain and China diverged dramatically starting around 1800. This one focuses on documenting the differences between the regions, with relatively little theorizing.

Some interesting differences of possible relevance to the divergence:

  • British per capita tax collections were 15 times China’s [1]; Vries emphasizes the underlying British bureaucratic competence.
  • Britain changed its tax rules often; China treated tax rules as if set in stone.
  • British tax policy caused it to promote standardization of a wide variety of weights and measures, which helped long-distance trades; China had nothing similar.
  • Britain’s taxation was more egalitarian than China’s (but still much less egalitarian than today).
  • British government debt looked recklessly high; China consistently had a surplus.
  • British elites wanted to keep the masses poor (to make them industrious); China’s elites seemed neutral or had slight preferences for the poor to prosper.
  • Most British workers were nearly slaves – laws restricted their mobility due to the expectation that most who left their area of work were beggars/thieves; China was less restrictive.
  • Britain condoned or supported powerful monopolies; China broke up concentrations of merchant power / capital under the assumption that they came at the expense of ordinary people.
  • Britain had three times as much farm land per capita as China.
  • Britain was more urban, so it had more commercial / monetary activity.
  • China denied that anything outside its borders mattered. Britain had a fairly global worldview.

Book review: Political Order and Political Decay, by Francis Fukuyama.

This book describes the rise of modern nation-states, from the French revolution to the present.

Fukuyama focuses on three features that influence national success: state (effective bureaucracy), rule of law, and autonomy (democratic accountability).

Much of the book argues against libertarian ideas from a fairly centrist perspective, although he mostly avoids directly discussing libertarian beliefs. Instead, he implies that we should de-emphasize debates over big government versus small government, and look more at effectiveness versus corruption (i.e. we should pull sideways).

Many of these ideas build on what Fukuyama wrote in Trust – I suggest reading that book first.

1.

War! What Is It Good For?. Fukuyama believes that war sometimes causes states to make their bureaucracy more efficient. Fukuyama is more credible here than Morris because Fukuyama is more cautious about the effects he claims to see.

The book suggests that young nations have some key stage where threat of conquest can create the right incentives for developing an efficient bureaucracy (i.e. without efficient support for the military, including effective taxation, they get absorbed into a state that does better at those tasks). Without such a threat, states can get stuck in an equilibrium where the bureaucracy simply serves a small number of powerful people. But with such a threat, politicians need to delegate enough authority that the bureaucracy develops some independence, which enables it to care about broader notions of national welfare. (Fukuyama talks as if the bureaucracies are somewhat altruistic. I think of it more as the bureaucracies caring about their long-term revenue source, when individual politicians don’t hold power long enough to care about the long term).

It seems plausible that China would have helped to lead the industrial revolution if it had faced a serious risk of being conquered in the 17th and 18th centuries. China’s relative safety back then seems to have left it complacent and stagnant.

2.

Fukuyama hints that the three pillars of modern nation-states (state, law, autonomy) have roughly equal importance.

Yet I don’t buy that. I expect that whatever virtues are responsible for the rule of law are a good deal more important than effective bureaucracies or democratic accountability.

Fukuyama doesn’t make a strong case for the value of democracy for national success, presumably in part because he expects most readers to already agree with him about that. I’ll conjecture that democracy is mostly a byproduct of success at the other features that Fukuyama considers important.

It’s likely that democracy is somewhat valuable for generating fairness, but that has limited relevance to what Fukuyama tries to explain (i.e. mainly power and wealth).

3.

Full-fledged rule of law might be needed to get all the benefits of the best modern societies. But the differences between good and bad nations seems to have originated well before those nations had more than a rudimentary version of rule of law.

That suggests some underlying factor that matters – maybe just the basic notion of law as something separate from individual leaders or ethnic groups (Fukuyama’s previous book says Christianity played an important role here); or maybe the kind of cultural advance suggested by Greg Clark.

Fukuyama argues that it’s risky to adopt democracy before creating effective states and the rule of law. He’s probably right to expect that such democracies will be dominated by people who fight to get the spoils of politics for their family / clan / ethnic group, with little thought to national wellbeing.

4.

National identity is important for producing the kind of government that Fukuyama likes. It’s hard for government employees to focus on the welfare of the nation if they identify mainly as members of a non-majority ethnic group.

He mentions that the printing press helped create national identities out of more fragmented cultures. This seems important enough to Europe’s success that it deserves more emphasis than the two paragraphs he devotes to it.

He describes several countries that started out as a patchwork of ethnic groups, and had differing degrees of success at developing a unified national identity: Tanzania, Kenya, Nigeria, and Indonesia. I was a bit disappointed that the differences there seemed to be mostly accidents of the personalities of leading politicians.

He talks as if the only two options for such regions were to develop a clear national identity or be crippled by ethnic conflict. Why not also consider the option of splitting into smaller political units that can aim to become city-states such as Singapore and Dubai?

5.

He makes many minor claims that sound suspicious enough for me to have moderate doubts about trusting his scholarship.

For example, he tries to refute claims that “industrial policy never works”, mainly by using the example of the government developing the internet. (His use of the word “never” suggests that he’s not exactly attacking the most sophisticated version of the belief in question). How familiar is he with the history of the internet? The entities in charge of internet tried to restrict commercial use until 1995. Actual commercial use of the internet started before the government made a clear decision to tolerate such use, much less endorse it. So Fukuyama either has a faulty understanding of internet history, or is using the phrase industrial policy in a way that puzzles me.

Then there’s the claim that the Spanish conquered important parts of the New World before the native nations had declined due to European diseases. Fukuyama seems unfamiliar with the contrary evidence reported by Charles C. Mann in 1491 and 1493. Mann may not be an ideal source, but he appears at least as reliable as the sources that Fukuyama cites.

6.

That leads into more general doubts about history books, especially ambitiously broad books aimed at popular audiences.

Tetlock’s research into the accuracy of political pundits has led me to assume that a broad range of “expert” commentary is roughly equivalent to random guessing. Much of what historians do [1] seems quite similar to the opinions of the experts that Tetlock studies. Neither historians nor political pundits get adequate feedback about mistaken beliefs, or get significant rewards for insights that are later confirmed by new evidence. That leads me to worry that the study of history is little better than voodoo.

7.

In sum, I can’t quite decide whether to recommend that you read this book.

[1] – I.e. drawing inferences from aggregations of data. That’s not to say that historians don’t devote lots of time to reporting observed facts. But most of those facts don’t have value to me unless I can generalize from them in ways that help me understand the future. Historian’s choices of what facts to emphasize will unavoidably influence any generalizations I draw.

Book review: Superforecasting: The Art and Science of Prediction, by Philip E. Tetlock and Dan Gardner.

This book reports on the Good Judgment Project (GJP).

Much of the book recycles old ideas: 40% of the book is a rerun of Thinking Fast and Slow, 15% of the book repeats Wisdom of Crowds, and 15% of the book rehashes How to Measure Anything. Those three books were good enough that it’s very hard to improve on them. Superforecasting nearly matches their quality, but most people ought to read those three books instead. (Anyone who still wants more after reading them will get decent value out of reading the last 4 or 5 chapters of Superforecasting).

The book’s style is very readable, using an almost Gladwell-like style (a large contrast to Tetlock’s previous, more scholarly book), at a moderate cost in substance. It contains memorable phrases, such as “a fox with the bulging eyes of a dragonfly” (to describe looking at the world through many perspectives).

The stock market reaction to the election was quite strange.

From the first debate through Tuesday, S&P 500 futures showed modest signs of believing that Trump was worse for the market than Clinton. This Wolfers and Zitzewitz study shows some of the relevant evidence.

On Tuesday evening, I followed the futures market and the prediction markets moderately closely, and it looked like there was a very clear correlation between those two markets, strongly suggesting the S&P 500 would be 6 to 8 percent lower under Trump than under Clinton. This correlation did not surprise me.

This morning, the S&P 500 prices said the market had been just kidding last night, and that Trump is neutral or slightly good for the market.

Part of this discrepancy is presumably due to the difference between regular trading hours and after hours trading. The clearest evidence for market dislike of Trump came from after hours trading, when the most sophisticated traders are off-duty. I’ve been vaguely aware that after hours markets are less efficiently priced. But this appears to involve at least a few hundred million dollars of potential profit, which somewhat stretches the limit of how inefficient the markets could plausibly be.

I see one report of Carl Icahn claiming

I thought it was absurd that the market, the S&P was down 100 points on Trump getting elected … but I couldn’t put more than about a billion dollars to work

I’m unclear what constrained him, but it sure looked like the market could have absorbed plenty more buying while I was watching (up to 10pm PST), so I’ll guess he was more constrained by something related to him being at a party.

But even if the best U.S. traders were too distracted to make the markets efficient, that leaves me puzzled about asian markets, which were down almost as much as the U.S. market during the middle of the asian day.

So it’s hard to avoid the conclusion that the market either made a big irrational move, or was reacting to news whose importance I can’t recognize.

I don’t have a strong opinion on which of the market reactions was correct. My intuition says that a market decline of anywhere from 1% to 5% would have been sensible, and I’ve made a few trades reflecting that opinion. I expect that market reactions to news tend to get more rational over time, so I’m now giving a fair amount of weight to the possibility that Trump won’t affect stocks much.

Book review: The Moral Economy: Why Good Incentives Are No Substitute for Good Citizens, by Samuel Bowles.

This book has a strange mixture of realism and idealism.

It focuses on two competing models: the standard economics model in which people act in purely self-interested ways, and a more complex model in which people are influenced by context to act either altruistically or selfishly.

The stereotypical example comes from the semi-famous Haifa daycare experiment, where daycare centers started fining parents for being late to pick up children, and the parents responded by being later.

The first half of the book is a somewhat tedious description of ideas that seem almost obvious enough to be classified as common sense. He points out that the economist’s model is a simplification that is useful for some purposes, yet it’s not too hard to find cases where it makes the wrong prediction about how people will respond to incentives.

That happens because society provides weak pressures that produce cooperation under some conditions, and because financial incentives send messages that influence whether people want to cooperate. I.e. the parents appear to have previously felt obligated to be somewhat punctual, but then inferred from the fines that it was ok to be late as long as they paid the price.[*].

The book advocates more realism on this specific issue. But it’s pretty jarring to compare that to the idealistic view the author takes on similar topics, such as acquiring evidence of how people react, or modeling politicians. He treats the Legislator (capitalized like that) as a very objective, well informed, and altruistic philosopher. That model may sometimes be useful, but I’ll bet that, on average, it produces worse predictions about legislators’ behavior than does the economist’s model of a self-interested legislator.

The book becomes more interesting around chapter V, when it analyzes the somewhat paradoxical conclusion that markets sometimes make people more selfish, yet cultures that have more experience with markets tend to cooperate more.

He isn’t able to fully explain that, but he makes some interesting progress. One factor that’s important to focus on is the difference between complete and incomplete contracts. Complete contracts describe everything a buyer might need to know about a product or service. An example of an incomplete contract would be an agreement to hire a lawyer to defend me – I don’t expect the lawyer to specify how good a defense to expect.

Complete contracts enable people to trade without needing to trust the seller, which can lead to highly selfish attitudes. Incomplete contracts lead to the creation of trust between participants, because having frequent transactions depends on some implicit cooperation.

The book ends by promoting the “new” idea that policy ought to aim for making people be good. But it’s unclear who disagrees with that idea. Economists sometimes sound like they disagree, because they often say that policy shouldn’t impose one group’s preferences on another group. But economists are quite willing to observe that people generally prefer cooperation over conflict, and that most people prefer institutions that facilitate cooperation. That’s what the book mostly urges.

The book occasionally hints at wanting governments to legislate preferences in ways that go beyond facilitating cooperation, but doesn’t have much of an argument for doing so.

[*] – The book implies that the increased lateness was an obviously bad result. This seems like a plausible guess. But I find it easy to imagine conditions where the reported results were good (i.e. the parents might benefit from being late more than it costs the teachers to accommodate them).

However, that scenario depends on the fines being high enough for the teachers to prefer the money over punctuality. They appear not to have been consulted, so success at that would have depended on luck. It’s unclear whether the teachers were getting overtime pay when parents were late, or whether the fines benefited only the daycare owner.

Will young ems be created? Why and how will it happen?

Any children that exist as ems will be important as em societies mature, because they will adapt better to em environments than ems who uploaded as adults, making them more productive.

The Age of Em says little about children, presumably in part because no clear outside view predictions seem possible.

This post will use a non-Hansonian analysis style to speculate about which children will become ems. I’m writing this post to clarify my more speculative thoughts about how em worlds will work, without expecting to find much evidence to distinguish the good ideas from the bad ones.

Robin predicts few regulatory obstacles to uploading children, because he expects the world to be dominated by ems. I’m skeptical of that. Ems will be dominant in the sense of having most of the population, but that doesn’t tell us much about em influence on human society – farmers became a large fraction of the world population without meddling much in hunter-gatherer political systems. And it’s unclear whether em political systems would want to alter the relevant regulations – em societies will have much the same conflicting interest groups pushing for and against immigration that human societies have.

How much of Robin’s prediction of low regulation is due to his desire to start by analyzing a relatively simple scenario (low regulation) and add complexity later?
