Book review: Dark Skies: Space Expansionism, Planetary Geopolitics, and the Ends of Humanity, by Daniel Deudney.

Dark Skies is an unusually good and bad book.

Good in the sense that 95% of the book consists of uncontroversial, scholarly, mundane claims that accurately describe the views that Deudney is attacking. These parts of the book are careful to distinguish between value differences and claims about objective facts.

Bad in the senses that the good parts make the occasional unfair insult more gratuitous, and that Deudney provides little support for his predictions that his policies will produce better results than those of his adversaries. I count myself as one of his adversaries.

Dark Skies is an opposite of Where Is My Flying Car? in both style and substance.

Book review: Four Battlegrounds: Power in the Age of Artificial Intelligence, by Paul Scharre.

Four Battlegrounds is often a thoughtful, competently written book on an important topic. It is likely the least pleasant, and most frustrating, book fitting that description that I have ever read.

The title’s battlegrounds refer to data, compute, talent, and institutions. Those seem like important resources that will influence military outcomes. But it seems odd to label them as battlegrounds. Wouldn’t resources be a better description?

Scharre knows enough about the US military that I didn’t detect flaws in his expertise there. He has learned enough about AI to avoid embarrassing mistakes. I.e. he managed to avoid claims that have been falsified by an AI during the time it took to publish the book.

Scharre has clear political biases. E.g.:

Conservative politicians have claimed for years – without evidence – that US tech firms have an anti-conservative bias.

(Reminder: The Phrase “No Evidence” Is A Red Flag For Bad Science Communication.) But he keeps those biases separate enough from his military analysis that I don’t find those biases to be a reason for not reading the book.

Book review: Now It Can Be Told: The Story Of The Manhattan Project, by Leslie R. Groves.

This is the story of a desperate arms race, against what turned out to be a mostly imaginary opponent. I read it for a perspective on how future arms races and large projects might work.

What Surprised Me

It seemed strange that a large fraction of the book described how to produce purified U-235 and plutonium, and that the process of turning those fuels into bombs seemed anticlimactic.

Book review: Warnings: Finding Cassandras to Stop Catastrophes, by Richard A. Clarke and R.P. Eddy.

This book is moderately addictive softcore version of outrage porn. Only small portions of the book attempt to describe how to recognize valuable warnings and ignore the rest. Large parts of the book seem written mainly to tell us which of the people portrayed in the book we should be outraged at, and which we should praise.

Normally I wouldn’t get around to finishing and reviewing a book containing this little information value, but this one was entertaining enough that I couldn’t stop.

The authors show above-average competence at selecting which warnings to investigate, but don’t convince me that they articulated how they accomplished that.

I’ll start with warnings on which I have the most expertise. I’ll focus a majority of my review on their advice for deciding which warnings matter, even though that may give the false impression that much of the book is about such advice.

Book review: The Causes of War and the Spread of Peace: But Will War Rebound?, by Azar Gat.

This book provides a good synthesis of the best ideas about why wars happen.

It overlaps a good deal with Pinker’s The Better Angels of Our Nature. Pinker provides much more detailed evidence, but Gat has a much better understanding than Pinker of the theories behind the trends.

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).

Hive Mind

Book review: Hive Mind: How your nation’s IQ matters so much more than your own, by Garett Jones.

Hive Mind is a solid and easy to read discussion of why high IQ nations are more successful than low IQ nations.

There’s a pretty clear correlation between national IQ and important results such as income. It’s harder to tell how much of the correlation is caused by IQ differences. The Flynn Effect hints that high IQ could instead be a symptom of increased wealth.

The best evidence for IQ causing wealth (more than being caused by wealth) is that Hong Kong and Taiwan had high IQs back in the 1960s, before becoming rich.

Another piece of similar evidence (which Hive Mind doesn’t point to) is that Saudi Arabia is the most conspicuous case of a country that became wealthy via luck. Its IQ is lower than countries of comparable wealth, and lower than neighbors of similar culture/genes.

Much of the book is devoted to speculations about how IQ could affect a nation’s success.

High IQ is associated with more patience, probably due to better ability to imagine the future:

Imagine two societies: one in which the future feels like a dim shadow, the other in which the future seems a real as now. Which society will have more restaurants that care about repeat customers? Which society will have more politicians who turn down bribes because they worry about eventually getting caught?

Hive Mind describes many possible causes of the Flynn Effect, without expressing much of a preference between them. Flynn’s explanation still seems strongest to me. The most plausible alternative that Hive Mind mentions is anxiety and stress from poverty-related problems distracting people during tests (and possibly also from developing abstract cognitive skills). But anxiety / stress explanations seem less likely to produce the Hong Kong/Taiwan/Saudi Arabia results.

Hive Mind talks about the importance of raising national IQ, especially in less-developed countries. That goal would be feasible if differences in IQ were mainly caused by stress or nutrition. Flynn’s cultural explanation points to causes that are harder for governments or charities to influence (how do you legislate an increased desire to think abstractly?).

What about the genetic differences that contribute to IQ differences? The technology needed to fix that contributing factor to low IQs is not ready today, but looks near enough that we should pay attention. Hive Mind implies [but avoids saying] that potentially large harm from leaving IQ unchanged could outweigh the risks of genetic engineering. Fears about genetic engineering of IQ often involve fears of competition, but Hive Mind shows that higher IQ means more cooperation. More cooperation suggests less war, less risk of dangerous nanotech arms races, etc.

It shouldn’t sound paradoxical to say that aggregate IQ matters more than individual IQ. It should start to seem ordinary if more people follow the example of Hive Mind and focus more attention on group success than on individual success as they relate to IQ.

Book review: War! What Is It Good For?: Conflict and the Progress of Civilization from Primates to Robots, by Ian Morris.

This book’s main argument can be broken down into two ideas:

  1. War creates powerful leviathans and occasionally globocops.
  2. The resulting monopoly on the use of violence is important for (or necessary to) creating low-violence societies.

(2) overlaps a lot with Pinker’s The Better Angels of Our Nature. Pinker’s version is sufficiently better that reading Morris’ version adds little value.

(1) is an old idea (“war is the health of the state”) that seems mildly controversial in its stronger versions. But Morris is relatively cautious here, admitting that many wars were destructive.

He goes around labeling many wars as productive or not, in a way that had me wondering whether he thought that was observable while the wars were in progress. When he got to World War II, it became clear that he considered that at least sometimes impossible: World War I initially looked harmful (ruining Britain’s globocop status), but when seen in combination with World War II he is able to classify it as productive (enabling the US to become a globocop).

Morris sometimes hints at a stronger version of (1) that would say leviathans or equivalent civilizing institutions couldn’t have been created without war. Morris never attempts to make much of an argument for such a strong claim. He does provide some arguments for the hypothesis that wars sped up the creation of peace-keeping leviathans. Whether that makes some wars good depends heavily on what would have happened without those wars, and Morris provides little insight about that.

If Morris were interested in testing his claims, wouldn’t he have discussed Switzerland? Swiss involvement in war over the past 200 years seems to consist of just a civil war in November 1847 with fewer than 100 deaths. Morris’ beliefs seem to imply Switzerland has lots of violence, yet Swiss homicide rates are unusually low (lower than the rest of western Europe). Maybe responding sensibly to the threat of war provides the benefits that Morris talks about, with few of the costs?

Much the book’s claims seem reasonable: wars did have some tendency to create stronger leviathans, and those leviathans did have some peace-keeping benefits. Yet those claims don’t come close to demonstrating the existence of “productive war”.
