The Grease that Oils the Wheels

The first book I ever read on body language was Allan Pease's Body Language: How to Read Others' Thoughts by Their Gestures. I must've been about twelve years old, and I got it out of the library thinking it would give me super powers. Instead, I'm pretty sure it messed me up for life.

In the intervening years I've read a fair few books on body language, interpersonal skills and the like, ranging in quality from spurious hokum to solid gold. In spite of this, I am still yet to develop super powers. This post is about what I've developed in their stead.

Tongue-Awareness Month
Once you notice that you point your feet at people you fancy, you'll never un-notice it. It's like becoming aware of your own breathing. When an unconscious action is brought to your attention, you'll second-guess how much of it you're supposed to do and lose all sense of what's natural. Where's your gaze going? How much are your hands moving? You're totally mirroring that guy. How obvious would it look if you shifted your position?

I think I've internalised quite a few of these cases of awkward posture-awareness, and in some cases developed some odd physical habits as a result. Still, every now and again I'll notice myself entering some textbook body language position, and then instinctively exiting it. This must look bizarre to observers.

Everybody Knows!
I once read a very simple magic trick in a best-selling book. In spite of the fact that its explanation is on a modest fraction of bookshelves up and down the country, I have regularly performed this trick for friends, on dates, or while trying to demonstrate a point, and not once has anyone said "you got that from [this pretty well-known book]". In spite of this experience, in the back of my mind I still expect everyone to have read it and know how it's done. Prescriptive people-skills advice feels quite similar.

Much like the above posture-awareness example, I've probably internalised any such advice to the point where it's become habit, but when you're first starting to apply something, it's easy to feel as if what you're doing is glaringly obvious. That book you read it in is freely available in shops. Anyone can pick it up and read it. Why don't they all know?

On the other hand...
I've had quite modest gains from my reading on this subject (by which I mean I'm disappointed that I'm not a combination of Derren Brown and Professor X by now), but one advantage of covering an assortment of material is that I am usually aware of when it's being used on me. With moderate regularity, I'll be talking with someone and realise they're trying to handle me with something they read in a book.

It's worth mentioning that the most naked attempts are the ones using methods from the most questionable sources1, but even adept people-handling has a certain feel to it. I am never entirely sure of the etiquette of saying "you learned that on a management course, didn't you?"

Just the right amount of sexism
At the beginning of this post I mentioned Allan Pease's book on body language. In collaboration with his wife, Barbara, he has written several books with titles along the lines of Why Men Eat Monster Trucks, and Women Can't Resist Ponies and Hair Brushes.2

Gender politics are a real, complex and salient feature of the social landscape, but even a "factual" approach to them involves walking a line between moronic overgeneralisation and cautious neutering into non-existence. Many of the people recommending Dale Carnegie's How to Win Friends and Influence People3 suggest getting a copy printed before 1960, as more recent updates to the book allegedly haven't fared well through various periods of heightened political sensitivity. My personal approach has been to include questionable material in my reading and trust my better judgement. That said, I'm not sure I'd trust the better judgement of a general readership (c.f. the pick-up artist community4).

Exciting new frontiers of awkwardness
I'm fairly sure I am never going to run out of awkward physical habits to gradually become aware of. One of my more recent endeavours in a similar vein is public speaking. Recording yourself perform and then watching it back is an exquisite form of torture that will never stop horrifying you. Once you start training yourself to notice your disfluencies ("um", "uh", and every other gormless-sounding noise that can come out of your mouth) or semantically null words ("like", "well", "basically", "right"), you craft this amazingly versatile stick to beat yourself with whenever you open your mouth. While you're struggling to keep them under wraps, you end up leaving what feel like enormous pauses when you talk, just begging to be filled with whatever stupid words pop into your head.

(I have fairly recently discovered I possess a very odd habit of speech: when I talk without any good idea of where I'm going, I tend to end phrases with a high-rising terminal. This creates an expectation [not least in my own brain] that I'm going to keep on talking, so I say something else. Before I know it, I'm locked in a huge, rambling sentence that I feel aesthetically compelled to prolong. When I realised why this was happening, and that I could just stop talking by saying something in a concluding tone of voice, it was like magic. I'm convinced there's some area of presentation skills or media training or speech therapy that deals with how patterns of speech impact the content in this way, but I'm yet to stumble across it.)

And yet...
For all my misgivings on this cluster of subjects, I can't really dismiss its value. It would be difficult to describe how spectacularly socially-awkward I was in my young adulthood. While it's hard to say how much of my current relative social competence is simply maturity and further life experience, theory is a core part of how I operate. Having explicit functional models of how people work is undeniably useful if you're that sort of person. You obviously can't develop social skills just from reading books, but the books can definitely help.

I should probably end this with some book recommendations for the socially apposite and destitute alike. I would heartily recommend the recent What Every Body Is Saying by Joe Navarro as an introduction to body language. The author's credentials are quite solid, and he's satisfyingly conservative about the realistic applications of body language. It's consistent with my other reading on the subject, but self-contained and sensibly broken-down by topic.

I would also recommend the aforementioned How to Win Friends and Influence People, though I am not currently in a position to comment on whether you should read a version printed prior to 1960. I listened to the Andrew MacMillan audiobook, (currently available in full on Youtube), which I would recommend as an agreeable medium for the material. Off the back of this post, I've ordered a 1953 copy off AbeBooks, so I may retract this recommendation in this light in a few months time. Especially if it gives me super powers.


  1. neurolinguistic programming, I'm looking at you. 

  2. While these books might not be totally devoid of valid observations, (I've never actually read any of them), in the absence of Alan and Barbara Pease having any substantial research credentials in this area, I'm going to suggest they most reliably offer insights into the domestic lives of Allan and Barbara Pease and their friends. 

  3. which is a lot of people, incidentally 

  4. It's worth mentioning that while I would draw into question the basic human decency of many PUA proponents, I wouldn't be as critical of their scholarship. If you can overlook the outrageously shitty attitude towards women, they have quite a few genuine insights about patterns of human behaviour. 

Triptych: a Theory of History

What did I know about history before reading a trio of books on the subject? This is a hard question to answer, but it's worth taking a crack at in order to figure out what I've gained from the experience.

A Personal History of History
History and I officially parted ways in secondary school, where a clash on the GCSE timetable robbed me of any opportunity to study a Humanities subject. This didn't seem like much of a sacrifice at the time. What is "geography" anyway? Who are the world's foremost geographers? What Nobel Prize category do they fall into? Once you siphon off geology and environmental sciences and anthropology and sociology and politics and economics, what's left? Why not just study those subjects instead, or at least sort them into more natural categories?

I digress. History. History, history, history. So what did I learn in History at secondary school? William the Conqueror didn't just wake up one morning and decide to invade England; historical events have causes, but they're manifold and difficult to tease out after the fact. There's a finite amount of evidence about the past, and as more time elapses between now and then, that amount gets smaller and smaller, so it becomes harder to piece together what happened. Recounting of historical events, both those made in the past and present, introduces bias into the record, because the people doing the recording are distanced from those events, either through time or culture or their own understanding. The closer a piece of evidence is to the event it pertains to, the stronger it is as evidence, but it is never free from scrutiny. Monarchs and priests argue a lot. Don't try to cross the Alps with elephants.

Add to this an arbitrary selection of historical knowledge about Medieval England, Ancient Rome, the rise of Islam, the Reformation, Tudors, Stuarts, and a couple of World Wars. That's not a terrible takeaway, to be honest. I don't have a massive amount of faith in the way contemporary schooling works, but considering I stopped officially learning history at the age of 13, the above paragraph doesn't seem to reflect too badly on the process. That said, I was one of the nerdy kids who joined Archaeology Club in Year 8,1, and some elements of this may have come from there, which was tailored to a smaller and more interested group.

Motivation
Quite a bit of time has passed between now and then, and in the intervening years I've taken up further interest in a lot of stuff that is undeniably "history". In addition, other disciplines that have my attention benefit from historical perspectives, either in the sense of that discipline having its own history that is worth investigating (history of philosophy, for example), or in the sense of pertaining to historical circumstances, events or data (such as economics).

"This stuff", I reasoned, "happened in the past. We only have historical records of it. It turns out there's a whole super-field dedicated to the study of history. It's called 'history'. Are there fundamental principles of the study of history which I could learn from reading some undergrad texts on the subject, which would help me in understanding it? Specifically, is there a general theory of history that I can learn?"

Long story short, there isn't. Unless I was staggeringly unlucky in my selection of books, there is no royal road to understanding past events and the remnants they've left for us. In mathematics, some things are described as by convention, in that they are the way they are because everyone in mathematics has agreed to do it that way for convenience; "we do it this way by convention", you may hear a lecturer say, "while this has to happen the way it does because of inexorable fundamental facts about the universe, and if we did it any other way, black would be white and up would be down and nothing would make sense any more." History as a discipline seems be made entirely out of convention, (to my newbie eyes a pretty robust set of conventions that broadly make a lot of sense), but the inexorable facts about how to interpret the past don't seem to exist.

GRYFFINDOR!
What do exist, however, are a variety of competing schools of thought around how it does and doesn't make sense to interpret history, and what it even means to do so. While all three of the books I read go over this to some extent, it is the primary basis for the first, The Houses of History, by Anna Green and Kathleen Troup. Divided into twelve chapters, each covers a broad "house" of historical inquiry, explaining its origin, proponents and motivations. The book is billed as a reader, and as such each chapter concludes in a sample text from a historian exemplifying those ideas. It seems the houses of history aren't quite so well-demarcated as Hogwarts; some chapters address fairly well-defined schools of thought (Marxism, for example), while others address much more general ideas, such as the use of sociological theory in historical analysis. Nonetheless, from my outside view, Houses of History does an admirable job of providing descriptions and examples of contemporary approaches to historical investigation.

Trivial Pursuits
Next on the list was The Pursuit of History by John Tosh. Lacking the chapter-by-chapter structure of Houses of History, The Pursuit of History has a similar goal: to move through different approaches to the titular pursuit of history, explaining what they're about and where they came from. It covers many of the same areas but with different emphases, elaborating on some of the more practical elements of history as a discipline. Tosh has a subtle sense of humour that I found quite pleasing, and goes to some greater lengths to expound upon answers to the question of what historians are actually doing, what its value is to society and what sort of role they should hold in broader discourse.

"Oh, but we've already met..."
History: A Very Short Introduction, by John Arnold, is obviously aimed at a more popular audience than the previous two books in this triptych, and this showed in a number of ways. For a start, it begins with a murder. While the previous two books were quite dry, this one is very much about getting the reader excited by the very notion of history. Something I found especially pleasing was an example of novel historical research carried out specifically for this book, in which the author walks us through the process of investigating the events surrounding an innocuous entry in a 17th Century ledger, following the life events of the individuals it mentions and putting them in a broader historical context. It also devotes a couple of chapters to a condensed history-of-history, going over historians featured in the previous two books in less of a distributed, topical meander.

Oh, the Humanities!
As hinted earlier, I find myself in foreign territory as far as the humanities are concerned. They have mildly askew alien values, and reading them is like driving along the edge of an uncanny valley. You never know when you'll tumble over the edge into a world where people take Sigmund Freud and Karl Marx seriously. Houses of History dedicates an entire chapter to psychohistorical analysis, which is apparently totally a thing that people still do, in spite of Freudian psychoanalysis being widely discredited by the overwhelming majority of contemporary psychologists, and the past few decades seeing phenomenal insights from the cognitive sciences2. That said, the sample text from this chapter had the spectacular name "The Legend of Hitler's Childhood", which I can't help but applaud.

Also Marx. So much Marx. Coming from an economics background, it's always mystifying as to why Karl Marx holds such sway in the humanities. Marx basically doesn't exist in any modern economics curriculum because the theoretical accounts of economic activity he provides are essentially wrong. No biggie. Lots of philosophers who thought about economic behaviour around this time were equally wrong; however relatively few of them have been canonised as one of the greatest thinkers of the 19th Century on the other side of the fence. Having now delved (very shallowly) into History's take on Marx, I'm perhaps a little less mystified, though I now have a few more Marxism Mysteries in my collection. It's hard to say whether I've come out ahead or not.

At some point, I will write the post on Talking Heads from History which I have been meaning to write pretty much forever. Now is not that point.

Takeaways
I started this triptych with the goal of excavating the tip of some general theory of history I was previously unaware of; one that might yield insights I can use when considering other ideas and disciplines in historical contexts. I wasn't successful in this regard, but I do feel like I'm walking away from it with a selection of intangible benefits. Rather than picking up some useful tools of thinking, I feel like I've gained broader appreciation and perspective, though only time (and presumably reading more history) will tell whether this is actually the case.

I am still quite confident that I shouldn't try to cross the Alps with elephants.


  1. Also Sign Language Club, Astronomy Club and the choir. Make of this what you will. 

  2. Somewhat analogously, in a recent Scott Aaronson interview he mentions how when reading books on the philosophy of physics or computing, it's like they're several decades behind the times, talking about the implications of problems that have been long resolved in their parent field. 

Coming Up...

Mostly for my own benefit, here's a run-down of subjects and books I plan on reading in the near future.

History/Historiography
I've been meaning to delve into this for a while, but I think watching Crash Course World History crystallised it for me. Some subjects can be more amicably divorced from their histories than others. You don't need to know about Francis Galton to understand statistics, but if you want to make sense of the Business Cycle, there's an implicit need for knowledge of historical events that pertain to the Business Cycle. It seems to me that having a basic introduction to the theory of historical inquiry may be useful. As such, I've put myself together a triptych introduction to the subject.

The three books I've opted for are The Houses of History, (which I'm about half way through at time of writing), The Pursuit of History, and History: A Very Short Introduction1. I've also picked up a copy of Jared Diamond's Guns, Germs and Steel, which I've been meaning to read for a while. The plan is to see what I make of it once I'm historied up to the eyeballs.

Mathematical Proofs
I have something of an embarrassing secret: I am terrible at mathematical proofs. I'm conversant with common methods and techniques, and I can follow some pretty hairy ones, but ask me to personally prove something, and most of the time I'll spend half an hour pushing vacuous algebra around a page before skulking off in failure. I am led to believe this isn't an uncommon problem for people in my position. I have a lot of "methods" under my belt, but haven't really done much by way of analysis. While this doesn't matter quite so much right now in my mathematical career, it will probably become a lot more important later on, so I suspect it'd be a good idea to tackle this one now.

With that in mind, I'm awaiting the arrival of How to Read and Do Proofs, which came recommended by the four corners of the internet, along with How to Solve It, which came similarly recommended, and satisfies the charm I am under as regards quaint books from decades ago which are presumably still in print because they're of genuine value. While I will likely review these books, I won't form them into a triptych. This is a case of reading as many books on the subject as it takes to not need to keep reading books on the subject any more.


  1. I've heard a few good things about the Oxford University Press Very Short Introductions series, and I expect to sample quite a few in the near future. Not only are they in broad alignment with my goals, but they're also ridiculously cheap on AbeBooks, and having a ~150-page volume I can polish off in an evening makes rounding off a triptych a lot more straightforward. 

(ding!)

A couple of weeks ago I finished reading Daniel Dennett's Intuition Pumps and Other Tools for Thinking. I'd recommend it, though it's not the focus of this post.

Early on in the book, two of the "tools" established by Dennett are certain words that he claims are strongly indicative of weak points in arguments. Specifically, these words are "surely" (which he claims is indicative of the author pleading a point he or she is in fact not entirely sure of), and "rather", (which he claims is often used to conceal a false dichotomy). I believe these claims to have some weight to them, though they're also not the focus of this post.

"What is the focus of this post?" I hear no-one cry. Well, having established these two words early on in the book, whenever they subsequently appear, Dennett suffixes them with "(ding!)". Sometimes the word appears in one of his own arguments and sometimes in those he is critiquing, but the purpose is to effectively draw your attention to their use. So effective, in fact, that when I was reading an unrelated piece of text last week, I hit the word "surely" and ding!ed.

I'm not sure whether this would be so effective for everyone, but I have the opportunity here to train myself to notice specific word usage. I've installed a regex browser extension (this one, for Chrome, is my weapon of choice, but I'm sure suitable alternatives exist for Firefox), and set it to append the (ding!) to a set of words I want to notice. For the time being I'm working with "surely", which I'm finding to have quite a bit of mileage.

You should consider how hard this post is for me to proof-read while this regex rule is in place. If I make a follow-up post in six months listing all the words I've added, that's going to be even more fun.

EDIT: Surely enough, a (ding!) crept into the draft of this post, and I spent about ten minutes wondering what was wrong with my incredibly simple regex that was causing two (ding!)s to appear

Of Siblings and Sea Sponges

Until our early twenties, my sister and I had almost identical academic histories, right up to and including dropping out of a physics degree. The only significant substitution was that she took an A-Level1in electronics while I took one in chemistry. This had an interesting side-effect: I have a paired control case for studying A-Level chemistry. It's especially interesting as I'm fairly sure that A-Level chemistry was one of the more practically useful academic endeavours of that period, even though I never went on to study it further.

There are so many common domestic activities where a working knowledge of chemistry is useful. Thickening a soup, thinning some paint, picking a suitable cleaning product or using the right glue all become a lot easier to do on the fly when you understand the principles behind them. I have learned a lot of useless stuff in my life2, but I've never regretted understanding what emulsification is, or how detergents work, or why acids are corrosive. I've never wished the knowledge of why glass and metal and rubber behave that way be replaced with something more useful. I also have a reasonable test for whether any given piece of knowledge is dependent on me having studied A-Level chemistry: I can just ask my sister.

You know what I didn't study at A-Level? Biology. I did one chemistry module in biochem, and I've picked bits up as an interested observer over the intervening years, but there's some alternative version of me in some Bizarro Biology A-Level world, wandering around with all sorts of knowledge of metabolic processes and enzyme production and protein synthesis, using the crap out of it in assorted everyday ways that I can't imagine. It's tantalising to think about Bizarro Biology A-Level me. So tantalising, in fact, that I've taken a few small steps towards becoming him.

You may already be familiar with brothers John and Hank Green as YouTube Internet Celebrities, who started vlogging to each other in 2007, and ended up with a committed internet following. They are both eloquent and diversely well-educated, with a broadly-appealing nerdy charisma and sense of humour. A year or so ago they started expressing frustration that while the internet is very informative, it's not necessarily as educational as they might like. There are many ways of learning a lot of atomic facts about a subject, but it takes a certain amount of effort to put those facts into a broader context where you actually start to appreciate what they mean. With this in mind, they started CrashCourse.

CrashCourse consists of playlists of 10-12 minute videos, with each playlist intending to provide a broad introductory overview of a subject. At present those subjects include Biology, Chemistry, Ecology, World History, US History and Literature. Over the past couple of weeks, I've worked my way through Hank's Biology playlist. It clocks in at about seven hours, and while I doubt I'm equipped for a Biology A-Level exam after that, I have more substantial foundations in place for further inquiry. I'm not very well-equipped for Chemistry A-Level right now either, but the useful concepts are still there.

The videos are produced with laudably high production values, and while they are watchable and entertaining, I believe they also succeed at the broader goal of being genuinely educational. "OK," they'll sometimes say, "this one is going to be pretty involved, but please bear with me; it's kind of important". I have a massive amount of respect for this approach, and feel it adds to the credibility of an educator if they have some faith in your motivations for learning.

While my biology appetite has been whetted, I'm not sure what to follow it up with. It is a massive subject, and yet it doesn't intersect too neatly with anything else I'm studying at the moment3. I may just let it brew for a while. There's also eight hours CrashCourse World History playlist sitting there, winking at me, and if I'm honest, I think I prefer John's delivery to Hank's.


  1. For non-Brits, A-Levels are among qualifications typically obtained between the ages of 16 and 18 before going to university. 

  2. I possess an alarming number of "facts" about starships, supernatural creatures and the metaphysics of fictional TV shows, which I'm sure will serve me well if I'm ever stuck in a piece of Star Trek/Buffy/Quantum Leap crossover fanfiction. 

  3. In actual expensive-piece-of-paper education, I've just finished a unit on medical statistics, and pharmacology/methods of action/chemistry crossovers is something that piques my interest when reading Derek Lowe's blog, but this would presumably require some pretty heavy and well-directed study before I have any appreciable understanding, which I then probably wouldn't have much use for. 

Precarious Armchairs and Filling the Gaps

I have a new rule: books I read for explicitly edifying purposes should be textbooks. I am allowed to read other books, but they go against entertainment in the ledger*, and don't count as learning any more than Terry Pratchett, Dilbert or Project Runway. **

I'm doing this so I can't convince myself that I understand a field of study when I don't. This can happen for a variety of reasons, but I think an especially common vector is being a part of the skeptic / pro-science / atheist crowd on the internet. As part of this crowd, you're introduced to a very shallow reading of a variety of enormous subjects (evolutionary biology, statistics, cosmology, logic, philosophy...), and especially if you take up skepticism / pro-science / atheism as political positions to be argued at all costs, you're going to abuse what little knowledge you have in defence of your protected beliefs and say a lot of stupid things. I shamefacedly hold my hand up and admit to doing this.

(A note to people who persist in doing this: it's piss-annoying, and if you ever grow out of it you will regret it more than any youthful fashion-blunder you can imagine. If you stop now, you will regret it a little less.)

There are slightly less embarrassing ways to scratch the surface of a subject and think you've exhausted it. A lot of popular science literature seems to do a good job of making the reader feel they've learned something, and a bad job of imbuing the reader with a sense there's more to learn. When you finish a pop-sci book on a subject you're unfamiliar with, you feel like your mind has been expanded, and compared to your still-unfamiliar peers, you can feel like a resident expert. It's as if all the condensed insight from the field has been given to you, and the messy underpinnings are something you're fortunate enough to not have to worry about.

It's easy to have an armchair understanding of a subject. You might know considerably more about that subject than the average person on the street, but that is a ridiculously low bar. There's a sense, I think, that moving from armchair understanding of a subject to pursuing it as part of a course of formal study is simply "filling in the blanks". My experience of diverse formal study is that while this is sometimes the case, on many occasions, those "blanks" turn out to collapse into vast crevices, and the fall can be very uncomfortable if you're not prepared.

As a result, I've decided the armchair is an unsafe place to theorise from. If a subject is important enough for me to be interested in, it's important enough for me to work through an undergrad textbook on that subject. This won't make me an expert in all these subjects, but that's not the point of the exercise; the point is to learn how much ignorance I have.

The first area where I've decided I don't know enough is philosophy. Courtesy of Abe Books, I've obtained Ernest Lepore's Meaning and Argument, Norman Melchert's The Great Conversation, and for good measure, Bertrand Russel's History of Western Philosophy. This seems enough to be going on with. As I finish each, I plan to report on what I feel I've learned from them.

* I don't actually have a ledger where I document all my media intake and meticulously label how worthy it is, though now the idea's been floated, I'm seriously considering it.

** I don't actually watch Project Runway. There is not enough helium in the world to float this idea high enough to make me consider it.
