Nurtureshock – Po Bronson and Ashley Merryman

“The central premise of this book is that many of modern society’s strategies for nurturing children are in fact backfiring — because key twists in the science have been overlooked.”

Can you tell if children are lying? Most adults believe they can: they also frequently believe that boys are more prone to lying than girls, and that younger children lie more than older ones. Sadly, none of that is true. Parents do no better than chance at telling whether random kids are lying, and only slightly better than chance with their own children. Gender does not correlate with lying, and younger children actually lie less than older ones. Less is a relative term, though: in household studies, 96% of kids lie, an average of once an hour for six year olds. Threatening punishment doesn’t appear to make a difference: what helps is emphasizing that telling the truth makes parents happy (since that is often the goal of the child anyway), and the value of honesty more generally.

For all that we were all kids once, it turns out our intuitions about what they are like are depressingly poor. Nurtureshock aims to capture some of the counter-intuitive or novel ideas researchers have found from actually working with large numbers of children, rather than just guessing (Ahem, Freud). Seeing their parents fight isn’t bad for children, it turns out, if they also witness a successful resolution. If the parents end the fight without resolving it, or move it upstairs or otherwise out of the child’s presence, on the other hand, children tend to be more aggressive and act out more afterwards.

Nurtureshock tries to cover a wide range of issues, sometimes at the price of oversimplifying. Some of the chapters are also fairly well known, at least to me, such as Carol Dweck’s work on fixed and growth mindsets. Others, though, raise some great points, ones parents may not even have considered, and even if the treatment is probably too brief to satisfy, it can serve as a useful starting point to tracking down more research. After all, research about kids is usually pretty cute, whether of children singing to themselves to resist eating a marshmallow, or managing to stand still for 2 minutes when asked to stay still, or 11 minutes if asked to mimic a soldier. A challenge for both parenting and teaching is that you often don’t see others parent or teach, and so rarely have your intuitions challenged: a little bit of critical reflection can go a long way.

Dear Undercover Economist – Tim Harford

“When a dinner party guest wonders how much to spend on a bottle of good wine, Dear Economist ignores the Good Wine Guide and reaches for the Journal of Wine Economics.”

What, you might wonder, is the secret to happiness? Harford, citing Kahneman, says that sex is best, but that exercise, food, and prayer are also good. In fact, all human contact is good, except for that with your boss, which is quite bad. The secret to happiness? Don’t have sex with your boss.

Tim Harford is a frequent writer for the Financial Times, and has also published several excellent pop economics books, including The Undercover Economist. Dear Undercover Economist, however, is a collection of advice columns he published in the FT. Written in the classic style of Dear Abby columns, they use economics to answer questions about love, family, careers, and other domains. He gives advice to a man who gives bad first impressions (give a signal of quality, like giving the girl theatre tickets for a third date with him when they first meet); a student who is too busy with his karate club activities to study (gains from trade: find a weakling to do his homework and beat up the weakling’s enemies); someone looking for missing socks (give up on them: instead, focus on interchangeable parts, and just buy all identical socks); and, in response to someone concerned about inflation and the shrinking size of Mars Bars, points out they are actually a very stable unit of account, with about 20,000 bars buying you a small car for the last 70 years.

This is classic pop economics, freakonomics-style. It takes the insights of economics, particularly signalling, screening, and trade, and applies them to problems outside economics’ traditional gaze. I’m not sure I’d take the advice myself, but the columns are entertaining and well written: you could do worse if you’re trying to learn some microeconomics for yourself, or if you’re a student taking microeconomics. After all, how many other opportunities will you have to make economics fun? Overall, a great romp through the insights of economics, applied to everyday problems.

What If: Serious Scientific Answers to Absurd Hypothetical Questions – Randall Munroe

“High in the North in a land called Svithjod there is a mountain. It is a hundred miles long and a hundred miles high and once every thousand years a little bird comes to this mountain to sharpen its beak. When the mountain has thus been worn away a single day of eternity will have passed.” – Hendrik Willem van Loon

I read a lot, but it’s rare I read a book I can recommend unconditionally. This is one of them, with the extra bonus you can read a lot of it in advance online to see if you agree. It’s insightful, it’s hilarious, and best of all it can give you a glimpse into how scientists think, working through the world from first principles.

The book is exactly what the title says: it gives carefully worked out answers to absurd questions, like what would happen if you swam in a nuclear waste pond (nothing – water is great radioactive shielding. Of course, trying to swim in such a pond would get you shot by the guards), hit a baseball going at .9c (Boom!), endured a robot apocalypse (the robots would probably slip on the mountain of skulls and most can’t open doors or pass those tricky rubber thresholds on lab doors. Even most battle drones would be stuck, “helplessly bumping against hangar doors like Roombas stuck in a closet.”) or lived in a world with love at first sight (people would want to be police officers or receptionists, since they make eye contact with the most people).

Munroe was a robotics engineer at NASA, so has good science credentials. He left to run his webcomic, xkcd (which I also highly recommend). His book, however, takes columns from a series he did online, What If, and puts them in convenient book form with some additions – you should definitely read the online column first to see if it’s your thing, and I’m not sure how much new content there is, to be fair.

The book is hilarious, as you’d expect from the author of xkcd. For me, the best part is that Munroe can’t seem to avoid thinking like a physicist. Keeping in mind I started my degree in physics, I love it: it reminds me of the great way scientists have of looking at the world. Analysis like:

“First, let’s start with wild ballpark approximations… I can pick up a mole (animal) and throw it.[citation needed] Anything I can throw weighs one pound. One pound is one kilogram. The number 602,214,129,000,000,000,000,000 looks about twice as long as a trillion, which means it’s about a trillion trillion. I happen to remember that a trillion trillion kilograms is how much a planet weighs.”

There is basically nothing I don’t love in that paragraph. This is how reasoning about the world should work, for oh so many reasons!

David & Goliath – Malcolm Gladwell

“David and Goliath is a book about what happens when ordinary people confront giants…from armies and mighty warriors to disability, misfortune, and oppression.”

The story of David and Goliath is well known, of course: a huge giant challenges any man of the Israeli army to single combat, all soldiers refuse in fear, young shepherd boy accepts and defeats giant with only a sling. The classic underdog story. Gladwell takes another perspective: the biblical tale matches the symptoms of acromegaly, a condition which leads to enormous growth, but also impairs vision. That explains why Goliath needed an attendant to lead him to battle, and why he did not respond to David having a sling: he couldn’t see! What gave the giant his great size, Gladwell argues, was also his greatest weakness.

The point, Gladwell argues, is a general one. We tend to assume that great strength will always win out, but in truth, underdogs can gain considerable strength from their underdog status, while giants can be severely disadvantaged by their size. The battle is much less one-sided than we might believe.

Gladwell applies this idea to issues ranging from dyslexia to class sizes and university choice. As usual, his examples are interesting and fun, which is what makes the book work. It’s less clear to me, though, what his thesis means. One concern is that perhaps adverse conditions just destroy the weak: though the idea of hardship as crucible is popular (and I find it personally appealing), it’s hard to disentangle that theory from the idea that hardship just destroys the weak and identifies the already strong as survivors.

Perhaps more significantly, however, he’s also vague on the concept of hardship. At one point, for example, he suggests that students would be better off going to a worse university, so they can be a big fish in a small pond: after all, the same number of students drop out of science at Harvard as at much lower ranked universities (which, by the way, if fascinating), but the worst students at Harvard are potentially stronger than the best at a weaker university. If one chooses a small pond, however, or equally chooses to hardship when it could have been avoided, is that still the same? It seems to me it is not: knowingly choosing to make things difficult for yourself, though potentially valuable, is likely not the same as being forced to undergo adversity. If adversity strengthens, too, one wonders what choosing a little pond does to your future potential.

All that said, I liked the book more that Outliers, and find his thesis appealing. We probably are too fixed in our conceptions of what is weak and what is strong, and we should realize that there is strength in overcoming and adapting to weakness, not just avoiding it.

Outliers – Malcolm Gladwell

First things first: I trust you are all following the landing of Philae with bated breath. Now, on to book review.

“Success is not a random act. It arises out of a predictable and powerful set of circumstances and opportunities.”

I’m generally a little hesitant about Malcolm Gladwell. He presents a tasting menu of ideas: not enough to satisfy or in many cases even know what you really think, but enough to arouse curiosity or provoke thought. That can be a good thing, of course, but his reliance on stories and anecdotes – though entertaining – makes me nervous. Because I can’t tell if there is any factual basis to what he’s saying, I end up walking away from a book with some interesting stories, but no real insights to draw on because I can’t tell whether his stories generalize to anything larger. What I read from him I must look up elsewhere.

That said, two of his books that I hadn’t read happened to be in the library, so I thought I’d give them a try. The first, Outliers, focuses on the idea of success. Gladwell argues that we tend to see genius as a unique trait, something that sets the elite apart. That misses the point: success is not achieved in isolation, but rather requires opportunities. No matter how smart or how talented, without opportunities genius cannot bloom.

At the extreme, the thesis is somewhat trivial; if you get hit by a bus, genius won’t mean much. Gladwell has a point, though: we tend to neglect this fact in everyday conversation, ascribing enormous weight to individual action. I wonder, however, if this is just a question of definitions rather than the profound point Gladwell seeks to make. True genius may lie in making the most of the opportunities you are given, and so consist not just of IQ but also hard work, self-discipline, and other virtues – whether that’s saying anything revolutionary, I’m less sure. To take the Stoic line, we cannot control the opportunities we are presented with by the outside world: all we can control is how we respond to them, and that is where genius – and virtue – lies.

The Sense of Style – Steven Pinker

“The starting point for becoming a good writer is to be a good reader. Writers acquire their technique by spotting, savoring, and reverse-engineering examples of good prose.” – Steven Pinker

Steven Pinker “writes like an angel.” – The Economist

Cotton clothing is made from is grown in Egypt. Did that sentence make sense to you? Probably not. It’s what’s called a garden path: a sentence that lures the reader into interpreting a phrase in one sense (in this case, cotton clothing), when in truth it is meant in another, a fact that is made clear only at the end of the sentence. They are, unsurprisingly, a good thing to avoid in good writing.

The Sense of Style is not really a prescriptive, ‘this is how to rite good,’ sort of guide, though some sections do give concrete guidelines. Instead, it is a study of what it is to write well; an effort to understand the basic principles that can illuminate and expose ideas in text.

What makes us bad writers? Several factors. First is a reluctance to take responsibility for our opinions – academics in particular hedge their sentences so much to avoid being wrong that they lose all coherence and meaning. Many of us also fall into the trap of writing about abstractions: good writers, Pinker argues, write with nouns and verbs, not adverbs and adjectives, so that the reader can visualize what is going on. Worst of all, however, is the Curse of Knowledge. We do not realize that readers don’t know what we know, and as a result, writers fail to explain jargon, explain logic, or provide detail, making their writing obtuse and obscure.

All is not lost. The answer, Pinker argues, is to write in classic style; to write as if you were in conversation with the reader, directing their gaze to something in the world. Good writers ensure their readers don’t have to keep a lot of information in their memory as they read, share their drafts with others and read aloud while editing, and above all attempt to write clearly and coherently, presenting ideas in an order designed to make them clear to the reader, not in which they occurred to the author.

The book is good reading for anyone who spends their time writing, whether in academia, journalism, business, or anywhere else. Since I finished, I’ve found myself rereading many of my own sentences over with Steven Pinker’s principles in mind, and if my writing isn’t quite up to his standard yet, it’s improving.

A final comment: writing well is in many ways about thinking well, and in his parting comments Pinker gives advice that applies to both. Good writers, he suggests, look things up; make sure arguments are sound; don’t confuse a personal experience with the state of the world; avoid false dichotomies; and base arguments on reasons, not people. If you never write another word in your life, it’s still good advice.

The Why Axis – Uri Gneezy and John List

“Without understanding that life is a laboratory, and that we must all learn from our discoveries, we cannot hope to make headway in crucial areas.”

Paying students for marks gives them an incentive to study. Does it also crowd out intrinsic incentives for the same, crippling students by making them unable to study when they are not immediately paid for it? If a gay couple tries to buy a car, does the dealership discriminate against them because they are inherently hostile to gays, or because they believe they can increase their profits by doing so? Should charities allow people to opt out of receiving mailings, and if so, will that increase or decrease donations?

If you are a teachers’ union, activist, or charity, you likely have strong opinions on the answer. What you may not have is any actual knowledge. Gneezy and List, two great experimental economists, argue that fundamental questions such as the best ways to educate, fight discrimination, and run businesses lie at the heart of experimentation. Without it, we cannot understand the world we live in, forced to reason by post hoc ergo propter hoc: that because things occur at the same time, one must cause the other. With experimentation, we can establish true causality, understanding how what we do affects the world around us.

To understand education better – and with the help of a $10 million dollar donation from some hedge fund managers – they have established their own schools, one focusing on teaching will-power and delaying gratification, and the other a more standard academic curriculum of reading, writing, and arithmetic. To understand discrimination, they tried having gay couples purchase cars while signalling they planned to check other dealerships, and found that discrimination disappeared; to understand charitable giving, they experiment with several different approaches, finding that having a pretty girl ask for donations and offering a lottery prize for donating are equally effective in increasing donations, but that the lottery has long term effects while the pretty girl does not. Giving people the opportunity to opt out of mailings is most effective of all, however, increasing initial donations, leaving long-term donations unchanged, and saving money on mailings.

The Why Axis is another in a stream of books by economists popularizing their work. As with many such, it is reasonably well written, and stocked full of anecdotes, stories, and examples. It is more interesting than most, however, because experiments provide particularly interesting fodder for discussion. In addition, Gneezy and List argue passionately for a more experimental way of looking at the world. Whether we are considering a new job, a new product, or a new policy, trying it out on a small scale provides information essential to avoiding blunders. To my mind, they’re definitely correct we would be better off if we experimented with different ways of doing things a bit more; in that spirit, pick up a paper or two of theirs to see if you find them interesting, and if so, the book might well be worth it.

The Ten Golden Rules of Leadership: Classical Wisdom for Modern Leaders – M.A. Soupios and Panos Mourdoukoutas

“With very few exceptions, we are all continuously bombarded with portraits of “successful” types who allegedly merit emulation…The difficulty lies in the fact that these dubious paradigms tend to glamorize lives that are as superficial and inane as they are unreflective.”

Leadership is always a bit of a fraught topic to write about: almost everyone has an opinion, and most comments come across as superficial at best. It’s also often treated as the silver bullet that could solve everything: if we only we had better leaders, we moan, healthcare/foreign policy/the environment/our favourite issue could be resolved in a heartbeat.

The reality, of course, is not so simple. Identifying exactly what makes a good leader, or what skills we would prize in one, is hard. I don’t personally see consultants or even most managers as models (no offense to them) – they’re more like drivers instead of leaders, to take Warren Bennis’ phrase. Charisma and charm are often necessary to be popular, but they’re not the same as leadership.

Soupios and Mourdoukoutas identify another possibility, based on classical wisdom. Leadership, they argue, comes from knowing yourself. Being reflective and thinking deeply about issues, though not idolized in modern media, is what gives you the ability to understand and empathize with subordinates. It can also give you a broader philosophy of life, one that helps guide you and provide direction. Leaders, after all, inevitably have to be in front of others, and to do that you need direction of your own.

For me, that highlights an important point. Lots of would-be leaders these days seem focused on leading for the sake of leading: they don’t mind where the crowd is going, they just want to be leading them there. I’m not sure that can work. One can drive a crowd in a direction from behind, but to lead one must be in front, and that suggests being there before the crowd. Sometimes the crowd follows and sometimes it doesn’t, but part of being a leader is not needing to look behind you every thirty seconds to see who’s there.

The book isn’t perfect: the introduction is well written and definitely worth reading, but as with many such books, several of the chapters can feel clichéd. It nevertheless raises a point well worth thinking about, and highlights a number of useful ancient texts to refer to. Better, perhaps, as a short article than a book, but still worth the read.

The Greatest Empire: a life of Seneca – Emily Wilson

“The greatest empire is to be emperor of oneself.” – Seneca

Depending on your perspective, Seneca is either heroically wise, a font of wisdom, or simply freakishly annoying, a hypocrite who could never live by his ideals. A Stoic philosopher who rejected the importance of the material world, from provincial origins he became one of the Roman Empire’s richest men (at one point, he ordered 500 identical tables made of citrus wood with ivory legs for his dinner parties, individually handmade), tutor then adviser to the emperor Nero, and one of the most powerful men in the world. Throughout his life, he would write books espousing noble ideals, and then be accused of failing to live up to them, by himself and by others. Seneca felt trapped and terrified by his power: unable to retire because Nero feared it would reflect badly on the legitimacy of the empire, Seneca would eventually be condemned to death. Like his life, Seneca would not even live up to his ideals of death: it would take him four attempts before he successfully committed suicide.

The Greatest Empire looks at Seneca’s philosophy in light of his life, and his life in light of his philosophy. This works well: much of Seneca’s work focuses on ideas of how to live in a world of rampant consumerism, how to achieve serenity in an uncertain world, what counted as success, and other themes epitomized by his life. As Wilson points out, one of the most charming parts of Seneca is that though he frequently fails to live up to his ideals, he is at least aware of these imperfections, and works consistently (though unsuccessfully) to overcome them. Each evening, he would reflect on his failures of the day in an effort to improve, and his reflective style would influence writers including Montaigne and Descartes.

Stoicism, Seneca’s philosophy, is interesting; based in similar precepts to Buddhism, it too argues that only virtue can lead to a happy life, and that all other things are indifferent. Unlike Buddhism, though, it argues that engagement with the world is essential. Seneca, as a flawed adherent, helps humanize it all: his struggle with how responsible he is for Nero’s appalling behaviour given that he was Nero’s tutor helps show how Stoicism can be used to moderate experience in the real world.

The Greatest Empire is not perfect. Due to the paucity of sources, it can sometimes feel like the links between Seneca’s life and his philosophy are being driven by what information is available, rather than flowing naturally. That said, it provides an accessible, interesting introduction to Seneca, to Stoicism, and to the Roman Empire under Nero. I personally find Stoicism appealing anyway, but whether you’re familiar with it already or reading it for the first time, understanding how it is exemplified – or not – by Seneca’s life is enlightening and insightful.

Vipassana Meditation Retreat – Dhamma Dipa

I’ve just gotten back from a 10 day silent meditation retreat, and thought I’d provide some initial thoughts for those considering it. In brief, it was 10 days on the Welsh-English border learning Vipassana meditation – the organization that runs it has centers all over the world. Discipline is strict: no communication of any kind with other meditators or the outside world, no reading or writing, no killing of anything, no intoxicants, about 11 hours a day of meditation. The idea is to work as if you were in isolation.

In essence, the philosophy behind Vipassana is that unhappiness is caused by craving things. Unfortunately, that’s an unconscious reaction; when we feel something, we either want more of it or less of it depending on the sensation. The only way to break the cycle, it argues, is to use meditation to train your unconscious mind and build a habit of not responding with craving when you feel something.

The bad first.

  • It was unbelievably tough. Just brutal. I wasn’t too worried about not talking for 10 days: I’m pretty happy staying in my head. What I didn’t anticipate was how tough it would be not to hear others talking. For 10 days, I had almost no external input: no new things to see or do, no conversations, no books. Everything I thought about had to come from within me. My mind started spading over the weirdest memories – books and events from decades ago – just in search of something to think about!
  • It could feel vaguely cultish at times. In justice, I don’t think it is at all; it’s just hard to make anything that involves a bunch of people sitting quietly in a room feel totally normal, particularly with a guy chanting in the background. It’s just so far outside our normal experience.

The good: Despite how tough it was, it was definitely worth it, for several reasons.

  • My meditation practice got a lot better. Anyone who has tried meditation knows how tough it is to focus your mind for long. I’m a lot better at it, I felt like I was really progressing and learning every day, and my understanding of how it works has dramatically increased.
  • It was interesting to try the monastic lifestyle. Centuries ago it wasn’t uncommon, but today it’s rare to try such a low-stimulus environment. I think you learn a lot about yourself, and learn to appreciate more subtle things in the world around you. Only by trying very different things, really pushing the envelope, can you find what you yourself enjoy.
  • It was a chance to think about profound issues like what an enlightened person would look like and what makes us happy. There are lectures in the evening on the philosophy behind it all, and it’s a great opportunity to really reflect on the deep issues we don’t have time for in our everyday lives. The lectures are fairly Buddhist, but you can ignore that part if you want.

Bottom Line: Worth it, but not for the faint of heart! I’m not sure they have Truth, but I think there’s definitely some worthy truths in it.

Addendum: it’s a system based on Buddhism, but for what it’s worth, I’m not Buddhist, nor do I have any plans to become so. The retreat center didn’t mind at all, and actively emphasizes they don’t expect conversion or even willingness to consider conversion.
