Palm Sunday by Kurt Vonnegut

A compilation of Vonnegut’s speeches, short pieces, and some autobiographical content, introduced and presented with amusing segues.

I quite enjoyed this work, mainly because I am a Vonnegut fan, just being honest here, but also because I was curious to know more about his life and that is what Palm Sunday emphasizes. Alternatively, I liked the various short writing more than the one long biographical piece – perhaps because they were funnier and/or had that typical poignancy mixed with absurdity.

Overall, great for fans and a decent work for those just getting started (but I wouldn’t recommend it as a first or second exposure to him).

Moral Minds by Marc Hauser

An impressive work that advances the idea of an innate moral grammar 'designed' by evolution and that is shaped in development by our environmental circumstances. Hauser presents numerous research findings related to human and animal morality, each time carefully parsing out valid inferences from fallacious conclusions due to potential confounds. Hauser presents different philosophical notions of how we moralize and argues for a “Rawlsian” creature, one that makes immediate moral appraisals because we seem to react before we think.

His arguments and analysis are much more sophisticated than I am likely implying (and this short review doesn't do the book justice). In fact, the final chunk of the book is such a good overview of current animal research and how it relates to different aspects of morality that it became a bit dry and detached from the main thesis of the book.

A bit of a challenge to finish, but this work is a wonderful repository of research on human and animal morality, and provides excellent analysis of the surrounding scientific and philosophical issues.

(The very astute blog follow might notice that I had planned to read this after Justice, after Rawls, over a year ago. Some things take time.)

Filthy Lucre by Joseph Heath

Almost everyone I know should read this book; yes, it is that worthwhile. By examining the major economic fallacies that confuse the ideological right and left, Heath performs a great service. While it might be useful to have some prior economics exposure before reading Filthy Lucre, it isn’t necessary. In fact, it would likely make the key message – things are complicated – more salient.

For those with some economics exposure, this book will be a nice refresher as well as likely teach you an important thing or two (that annoyingly wasn’t covered in your previous classes).

Finally, if you have a great deal of experience with economics, as in you don’t have time to read this because you are working on your doctoral dissertation in economics, then you should buy it for a friend to help them better understand the economic way of thinking and avoid the common fallacies most make.

Personally, I enjoyed the reminder of complexity and how changing incentives within systems can have ripple effects within and outside of it, and how some core aspects of human behaviour are largely unchangeable. I appreciated learning about the cost of collecting taxes, the costs of transference, the importance of markets as instruments for organizing exchange, and the impulsivity of the poor. The book sometimes meta-analyzed analyze economics from a wide stance and this helped me understand the idea that government and private organizations are different ways of providing services in exchange for resources. The parts that stood out the most were (1) that if you want a more equitable society it is often better to transfer income than it is to fiddle around with prices and controls; and (2) the Second Best Theorem – (from Wikipedia): In welfare economics, the theory of the second best concerns what happens when one or more optimality conditions cannot be satisfied. Canadian economist Richard Lipsey and Australian-American economist Kelvin Lancaster showed in a 1956 paper that if one optimality condition in an economic model cannot be satisfied, it is possible that the next-best solution involves changing other variables away from the ones that are usually assumed to be optimal.

This means that pro-market ideologues cannot automatically say that even though an economic situation isn’t optimal, because it is 98% percent optimal that is almost as good. It could be that that high percentage doesn’t translate into things being nearly as good and some (usually disdained) economic correction might be necessary. Arthur Ripstein has very useful analogy to understand why 98% might not be almost as good: Say you want to go to Hawaii, would you consider a flight that gets you 98% of the way there almost as good as one that goes 100%? No, you’d end up in the ocean. In short, situations have to be taken on a case by case basis.(Why was this never mentioned to me?!)

Go read the book and try to ignore its unoptimal title and subtitle (from a marketing perspective of course).

Future Babble by Dan Gardner

I predict that you will find this review informative. If you do, you will congratulate my foresight. If you don’t, you’ll forget I was wrong.

My playful intro summarizes the main thesis of Gardner’s excellent book, Future Babble: Why Expert Predictions Fail – and Why We Believe Them Anyway. Gardner, a columnist for the Ottawa Citizen and author of the bestselling Risk, returns to the format that made Risk such a success: Find some interesting psychological research from the past few decades; describe the research in accessible and pithy prose for a general audience; emphasize cognitive biases; extrapolate the research findings to popular events to indicate why they matter; and imply that we should change our behaviours and policies.

In Future Babble, the research area explored is the validity of expert predictions, and the primary researcher examined is Philip Tetlock. In the early 1980s, Tetlock set out to better understand the accuracy of predictions made by experts by conducting a methodologically sound large-scale experiment. Gardner presents Tetlock’s experimental design in an excellent way, making it accessible to the lay person. Concisely, Tetlock examined 27450 judgements in which 284 experts were presented with clear questions whose answers could later be shown to be true or false (e.g., “Will the official unemployment rate be higher, lower or the same a year from now?”). For each prediction, the expert must answer clearly and express their degree of certainty as a percentage (e.g., dead certain = 100%). The usage of precise numbers adds increased statistical options and removes the complications of vague or ambiguous language.

After letting this impressive experiment run its course for several years and crunching all the numbers to see how the predictions bore out, Tetlock found the surprising and disturbing truth “that experts’ predictions were no more accurate than random guesses.” (p. 26) An important caveat is that there was a wide range of capability, with some experts being completely out of touch, and others able to make successful predictions.

“What distinguishes the impressive few from the borderline delusional is not whether they’re liberal or conservative. Tetlock’s data showed political beliefs made no difference to an expert’s accuracy. The same is true of optimists and pessimists. It also made no difference if experts had a doctorate, extensive experience, or access to classified information. Nor did it make a difference if experts were political scientists, historians, journalists, or economists.” (p. 26)

The big difference is in the way the experts think.

The experts who did poorly were not comfortable with complexity and uncertainty, and tended to reduce most problems to some core theoretical theme. It was as if they saw the world through one lens or had one big idea that everything else had to fit into. Alternatively, the experts who did decently were self-critical, used multiple sources of information and were more comfortable with uncertainty and correcting their errors. Their thinking style almost results in a paradox: “The experts who were more accurate than others tended to be less confident they were right.” (p.27)

Gardner then introduces the terms 'Hedgehog' and 'Fox' to refer to bad and good predictors respectively. Hedgehogs are the ones you see pushing the same idea, while Foxes are likely in the background questioning the ability of prediction itself while making cautious proposals. Foxes are more likely to be correct. Unfortunately, it is Hedgehogs that we see on the news. This is even more concerning as one of Tetlock’s findings was that “the bigger the media profile of an expert, the less accurate his predictions.” (p.28)

Gardner did such a superb job in the first chapter that you almost don’t need to read the rest of the book. Those with a background in psychology, as well as the seasoned Skeptic, will see some familiar faces: confirmation bias, hindsight bias, negativity bias, optimism bias, partisan bias, status quo bias, availability heuristic, cognitive dissonance… etc. Given that most could use a primer or a refresher on such biases, I do recommend the rest of the book for those with less of a background, as the following chapters usefully illustrate the key findings with various examples to increase understanding and provide greater depth of analysis.

Future Babble would make a great gift, and I hope that Gardner’s popularization of Tetlock’s work succeeds and the issues raised become part of a larger discussion on the validity of expert predictions.

Appendix (of sorts)

So ends the book review proper. Below I examine the book in more detail by going chapter by chapter, presenting some of my thoughts and notes. This content will likely be useful to those who want more detail, but it might be especially useful for those who have already read the work or who are looking to tease out to discussion points.

Chapter 2 – The Unpredictable World

An exploration into how many events in the world are simply unpredictable. Gardner discusses chaos theory and necessary and sufficient conditions for events to occur. He supports the idea of actually saying “I don’t know,” which many experts are reluctant to do.

Chapter 3 – In the Minds of Experts

A more detailed examination of Hedgehogs and Foxes. Gardner discusses randomness and the illusion of control while using narratives to illustrate his points à la Gladwell. This chapter provides a lot of context and background information that should be very useful to those less initiated.

Chapter 4 – The Experts Agree: Expect Much More of the Same

An interesting and almost amusing analysis of how the rise of Japan was the big fear in the US in the early 1990s, and pretty much none of it came true. He wisely mentions how the same concerns are occurring with China now. Although these concerns might be true, we should be wary of believing them. Gardner really drives home the notion that an ordinary person has about as good a chance at making correct predictions as most experts.

I found two flaws in this chapter, neither major but worth noting.

Flaw #1: Gardner uses a gross national income statistic to compare the US and other countries, but he doesn't per capita measures (p.94). This is misleading and doesn’t fit with the rigour of the rest of the book.

Flaw #2: Gardner could have had a more nuanced discussion of Tetlock’s work and how it fits into the status quo problem. The issue here is that Tetlock found that if you predict “no change,” you’ll actually do a decent job predicting things. A related notion is the status quo bias, where people assume that things will continue as they are. This is a problem because people invalidly extrapolate trend lines. There is a subtle distinction here between assuming that the present circumstances won’t change (good for prediction) and assuming that indicators in the present are valid predictors of future circumstances (bad for prediction). I don’t think it would have been too much trouble to tease this out (if only in a footnote).

Chapter 5 – Unsettled by Uncertainty

While there was a lot of interesting information in this chapter, it felt disjointed and had a few too many anecdotes for my comfort. It was mainly stories of how bad things were in the 1970s, or how dire the predictions were, and how nothing that bad came to pass. It might be the weakest chapter, but the social/intellectual history was decent. To be fair, a different reader might enjoy having the concepts elaborated upon. The problem for me is that once Gardner displayed Tetlock’s findings in the early chapters, further anecdotal information does not increase how convinced I am.

Chapter 6 – Everyone Loves a Hedgehog

More about predictions and how the media picks up hedgehog stories and talking points without much investigation into their underlying source or concern for accuracy.  It is a good demolition of the absurdity of so many news “discussion shows.” Gardner demonstrates how the media prefer a show where Hedgehogs square off against each other, and it is important that these commentators not be challenged lest they become exposed and, by association, implicate the flawed structure of the program/network.

Gardner really singles out certain people, like Paul Ehrlich, and shows how they have been wrong many times and yet can still get an audience.

Minor issue: If you check footnote 56, you’ll see Gardner admit to an error that he exposes numerous others making in the body of the text. I wondered why he did this in a footnote. Was he concerned that admitting he didn’t check common wisdom for accuracy would undermine his authority as a columnist and writer?

Chapter 7 – When Prophets Fail 

This might be the most entertaining chapter as it looks at prophets and prophecies, including experts who predicted Y2K chaos and calamities that never happened. There is a good exploration of Leon Festinger’s cognitive dissonance, which can generally be explained by saying that two or more beliefs come into conflict and they are usually resolved in a self-enhancing manner, putting truth as a lower priority. Regarding the theme of this book, “a mind deeply committed to the truth of a predication will do almost anything to avoid seeing evidence of the prediction’s failure for what it is.” (p.196)

Gardner uses a nice analogy, describing dissonance as a cognitive migraine and self-enhancing belief as a pill that makes the pain go away. Once again, there are too many anecdotes for my tastes, but it is useful as case studies illustrate the concerns and help the reader understand and hopefully apply the lessons thereof.

The chapter opened with a great quotation by John Maynard Keynes: “When the facts change, I change my mind. What do you do, Sir?”

Finally, it is in chapter 7 that Gardner writes one of his best passages:

 “An assertion that cannot be falsified by any conceivable evidence is nothing more than dogma. It can’t be debated. It can’t be proven or disproven. It’s just something people choose to believe or not for reasons that have nothing to do with fact and logic. And dogma is what predictions become when experts and their followers go to ridiculous lengths to dismiss clear evidence that they failed.” (p. 236)

Chapter 8 – The End

Gardner really pulls it all together in the last chapter with a good flow and summary of aforementioned themes and facts without it feeling repetitive or awkward. Helpfully, Gardner provides specific examples of better ways to think about issues (the Fox approach). One can only hope that these tactics will be appropriate and humility will increase along with accuracy of predictions.

Once again, there are nice phrases throughout and he knows how to write quotable prose.

So, was my prediction correct?

Jeeves and the Feudal Spirit by P.G. Wodehouse

This is yet another entertaning story about English gentleman Bertrand Wooster and his gentleman’s gentlemen, Jeeves by Wodehouse (see past reviews for other Wodehouse works). Feudal Spirit is similar to Thank You, Jeeves in that it is full novel, and similar to all the others in that J. Cecil performs the audio presentation wonderfully and Bertie gets into hijinks of which Jeeves is eventually able to bail him out.

Although enjoyable and worthwhile, I don't think it was as good as some of the four works I've read (but that could have been to being less in the mood for it at the early stages of the work).

The Black Book of Canadian Foreign Policy by Yves Engler

This book is incredibly important and incredibly frustrating, but overall it is worthwhile. Engler's mission is to describe incidents where the Canadian government or Canadian business engaged in illegal, immoral or suspicious activity. He does this for over 50 countries. Using a sentence from the last chapter (edited for concision), his general thesis is that "Canada's role in world affairs has been consistently pro-empire, pro-colonial and serving narrow corporate interests." 

After reading page after page of sketchy dealings in various countries, it is hard not to agree with him. It certainly seems there have been numerous and various dealings that are unjust and wouldn't be tolerated in our own country. The problem is that the content could have been far more contextualized, with better background events and opposing arguments being presented and critiqued. Additionally, his referencing, although abundant, was done in an annoying style.  The book wasn't a happy read, but the content is just so important, if only to prompt further investigation and examination of Engler's claims.

If someone were to complaining that the book was full of half-truths, I'd be sympathetic and say that that might be true... but add that his half-truths were just the opposite of the half-truths to which we have become accustomed.  

Recommended.

Island of the Sequined Love Nun by Christopher Moore

A light and zany novel that follows a screw-up pilot on his adventures with a cargo cult and missionaries who may not be helping the islanders as much as harming them. I haven't read anything by Moore before and I was looking for some vacation reading, but I found the book just wasn't smart enough. It seems I was looking for something more like Tom Robbins, which is zany and quirkly and intelligent, instead of just zany and prose which wasn't noteworthy.

I can't say I recommend it unless you want something without almost any social commentary or provocative ideas.
