Music Property

The topic of intellectual property gets me every time. As much as I am opposed to the notion of property in general, intellectual property is a complete farce. Along with Rick Beato and David Bennet, Adam Neely is one of my three main music theory staples on YouTube. Here, he goes into more depth than I would have expected, but it’s worth hearing the perspective of a musician. I won’t break down his video fully because it speaks for itself. Instead, I’ll share my thoughts and pull out highlights.

Podcast: Audio version of this page content.

November 8th, 1548 is the day in history that the French King Henri II opened the door to intellectual property, an obvious giveaway to a benefactor, creating a publishing monopoly. He turned community cultural knowledge into property, turning the benefit of many into the benefit of one. This is the crux of capitalism—favouring the one over the many.

Before continuing, it seems that there is a schism in the legal system itself. In fact, it is very fractured even within this small domain. At the same time it wants to be precise and analytical, it’s dealing with a subject that cannot be analysed as such. To add insult to injury, it exempts musicians and musical experts and requires music consumers to decide the outcomes of trial cases. To be fair, even relying on so-called experts would lead to mixed results anyway. They might as well just roll the dice. This is what happens when right hemisphere art enters a left hemisphere world.

nature + work = ownership

Adam establishes a grounding on the theory of property rights à la John Locke’s ‘sweat of the brow’ concept, wherein nature plus work equates to ownership. He then points out how intellectual property has even shakier ground to stand on. It relies rather on notions of originality and creativity, two concepts that have no intersection with the left-hemisphere heavy legal and jurisprudence systems. Moreover, like pornography, these things cannot be defined. They need to be divined. Divination is no place for lay jurists. It’s a recipe for disaster. The entire English court system is rife with problems, but the left-brainers feel these are just trivial devils in the details. I beg to differ, yet I am voiceless because I won’t participate within their frame.

Adam also points out how out of date the law is insomuch as it doesn’t recognise much of the music produced in the past few decades. Moreover, the music theory it’s founded on is the Romantic Era, white European music that often ties transcriptionists in knots. If the absence of certain words to emote experience is a challenge, it’s even worse for musical notation.

In any case, this is a hot-button issue for me on many levels, and I needed to vent in solidarity. This video is worth the 30 minutes run time. His ham sandwich analogy in part V works perfectly. It’s broken into logical sections:

  1. 0:00 Intro

Give it a listen. Cheers.

Schizoid Workplace

What is Schizophrenia?

Most people have heard the term schizophrenia. It’s a mental health pathology wherein people interpret reality abnormally. To oversimplify to make a point, in a ‘normal’ brain, the left and right hemispheres operate together to regulate bodily functions and to interpret the world we live in. In brief, schizophrenia is a condition where the left cerebral hemisphere overly dominates the right. Some might be led to believe that schizophrenics interpret reality irrationally, but the opposite is true. Schizophrenics are hyperrational to a fault.

Schizophrenia has been on the rise this past half century or so, but this might just be a symptom of Modernity, as cultures are also experiencing a leftward shift—a shift toward hyperrationality. Cultures have swung like a pendulum from left-hemisphere-dominance to right dominance and back through the ages, but we may be seeing an uncorrected swing further and further to the left, led by science, followed by commerce and politics, dangerously close to the territory of schizophrenia, if not already occupying this territory. Allow me to briefly summarise how the hemisphere function to help the reader understand what it means to be too far left or right.

Cerebral Bilateral Hemispheres

Most people experience the world—what some otherwise known as reality—with both cerebral hemispheres, and each hemisphere has a function. In a nutshell, the right hemisphere experiences reality holistically, which is to say that it views the world through a Gestalt lens. The right hemisphere is open and divergent. It is creative—generative. It knows no categories or subdivisions. All is one and connected. I like to refer to this as Zen. Many people can relate to this Zen notion. The right hemisphere is a creative and empathetic centre that only knows the world as it is presented—without words or naming. Intuition lives here. It distinguishes differences in the world in a manner similar to that of a preverbal child who can tell mum from a bowl of porridge without knowing the word for either. Children are right hemisphere creatures. As we mature toward adulthood, the function of the left hemisphere increases to offset the dominance of the right.

The left hemisphere is the sphere of intellect. Its function is to categorise, to create symbols—words, names, labels, icons, and so on. It doesn’t know how to create, intuit, or empathise. In fact, it doesn’t even experience the world as presented; it relies on re-presentation. To borrow from a computer analogy, when it experiences something in the world, it caches a symbol. Where the right hemisphere experiences a tree and just appreciates its ‘treeness’, and it doesn’t know that it’s a tree by name. It’s just another thing in the world. The left hemisphere, on the other hand, notices these things with ‘treeness’ and categorises them as trees—or des arbres, árboles, Bäume, 木, درختان , पेड़, or whatever. And it reduces the tree to an icon, so it can file it away for later retrieval to compare with other tree-like inputs.

The left hemisphere is where difference, the sense of self, and ego come from

The left hemisphere is where difference, the sense of self, and ego come from. Where the right hemisphere is open and divergent, the left hemisphere is closed and convergent. It is particularly egotistical, stubborn, and always thinks it’s right if I can anthropomorphise analogically. The left hemisphere knows no nuance, and it doesn’t recognise connotation, metaphor, allegory, or allusion. Everything is literal.

The left hemisphere can use similes and understand that a man is like a tiger, but it takes the right hemisphere to know that a man is a tiger, has metaphorically embodied the tiger and assumed its form, say in the manner of indigenous Americans. Poetically, there is a difference between being a tiger and being like a tiger. The left will have none of this. The response to hearing ‘he was a tiger’ would either result in ‘no he isn’t, he’s a human’ or ‘someone must be talking about a male tiger’. The nuance would be lost.

At the risk of further digression, this is why a poem can’t be dissected for meaning—this despite so many valiant attempts by high school teachers and undergraduate professors. Dissecting a living poem is like dissecting a living animal. You might learn something, but at the risk of devitalisation—you’ve killed the subject. It’s like having to explain a joke. If you have to explain it, it didn’t work. You can’t explain a work of art or a piece of music. The best you can do is to describe it. Although we’re likely familiar with the adage, “A picture is worth a thousand words”, a thousand words is not enough to do more than summarise a picture. This sentiment is captured by Oscar Wilde when he wrote, “Education is an admirable thing, but it is well to remember from time to time that nothing that is worth knowing can be taught.” Education is a left-brain function, that can be stuffed like a sausage, but no amount of education can make someone feel a work of art, music, or poetry. This can only be experienced and is apart from language.

A Tree is not a Tree

As already noted, schizophrenics are hyperrational. They are devoid of the empathy and intuition afforded by the right hemisphere. So, they fail to connect the parts to a constructed whole. They presume that a whole is constructed of parts. This is the mistake of Dr Frankenstein, that he could construct a man from parts, but all he could manage is to construct a monster.

In the experienced world, there are only whole objects as experienced by the right hemisphere. As humans, we break them down for easier storage and retrieval, but this is like lossy compression if I can risk losing some in technical lingo.

But a tree is not built from parts. It’s just a tree. We can articulate that a tree has a trunk and roots and branches and leaves and seeds and blooms, but it’s just a tree. The rest we impose on it with artificially constructed symbol language. This is what post-modern painter Rene Magritte was communicating with the “Ceci n’est pas une pipe” inscription in his work The Treachery of Images—This is not a pipe. He was not being cute or edgy or trying to be clever. He was making the point that the symbol is not the object.

In the manner that the image is not the pipe, it’s been said that to document a system is to make an inferior copy. The documented system is less optimal. This may feel counterintuitive. In fact, you may even argue that a documented system allows subsequent process participants to plug into the system to allow it to continue to operate into perpetuity. Whilst this is true, it comes at a cost. I’ll leave this here for you to ponder. The right hemisphere understands the difference. The document is not the process.

Getting Down to Business

If you’ve been following along, you may have already noticed that the left hemisphere looks and sounds a lot like the business world. Everything is systematised, structured, and ordered. We have all sorts of symbols and jargon, processes, and procedures. Everything is literal. There is no room for metaphor. There is no room for empathy. HR instructs that there be empathy, but they might as well instruct everyone to speak Basque or Hopi. In fact, it’s worse because at least Basque and Hopi can be learnt.

Sadly, this leftward shift isn’t limited to the world of commerce. It’s affected science, politics, and entire cultures. It’s caused these entities to abandon all that isn’t rational as irrational. But empathy and intuition are irrational. Science says if you can’t measure it and reproduce it, it’s not worth noting, but science is not the arbiter of the non-scientific realm. Business takes a similar position.

Politics of the Left (Hemisphere)

And politics creates categories: left and right, red and blue, black and white, men and women, gay and straight, and this and that. All of this is all left-hemisphere debate.

Categories and names are exclusive provinces of the left hemisphere. If you are hung up on an ideology, whether Democracy, Republicanism, Marxism, or Anarchism, you’re stuck in your left hemisphere. If you defend your positions with logic and words, you’re stuck in your left hemisphere. If you can’t imagine an alternative, you are really stuck in the left. I’ll stop here.

Science and Scientism

How did we get here and come to this? Science was receptive to right hemisphere influence up until about the 1970s. That’s where Scientism began to take hold. Scientism is when faith in science becomes a religion. I feel that many scientists today are less likely to hold a belief in Scientism as a religious belief. Paradoxically, I think this is more apt to be a faith held by non-scientists. Unfortunately, this faith is exploited by politics as exemplified by the recent trust in science campaign perpetrated by politicians, which is to say non-scientists with their own agenda, whether they practised Scientism or not.

The problem is that the left hemisphere has an outsized ego. It thinks it’s always right. In practice, it’s right about half the time. Because of its reliance on stored data and a ‘belief’ that it doesn’t need to fresh its data until it’s effectively overwhelmed and acquiesced. It fails to give enough weight to the experienced world, so that it shifts belief further and further left, which is to say further from reality as it is.

It trusts the symbol of the tree more than the tree itself. We may all be familiar with stories of cars driving down train tracks and off cliffs because the SAT-NAV user put more faith in their device than the world outside. This is the risk companies face as well, choosing to believe that the documented process is superior to the system in and of itself.

Getting on About?

You may be wondering what inspired me to write this and where I get my information. My realisation started in chapter 9 of The Matter with Things and was reinforced by this video interview by its author, Iain McGilchrist.

Actually, it started even before this with The Corporation, a Canadian documentary and companion book released in 2003. One of the points of The Corporation is to articulate the parallels between corporate behaviour relative to the definition of psychopathy as presented in The Diagnostic and Statistical Manual of Mental Disorders, henceforth DSM. Per Wikipedia, the DSM ‘is a publication by the American Psychiatric Association for the classification of mental disorders using a common language and standard criteria and is the main book for the diagnosis and treatment of mental disorders in the United States and is considered one of the “Bibles” of psychiatry’. Essentially, corporations ticked all the boxes.

Methodologically, this assertion is a bit weak, but it is at least sometimes entirely valid despite provoking an emotional trigger reaction. Nonetheless, this established corporations as pathological entities. But that is not my focus here. It simply tilled the soil for me to be more receptive to this topic. This topic is less about the legal fiction that is a corporation and more about the people embodied in it. From the height of the C-suite to the workaday staff, floor workers, warehouse workers, and the mailroom. Do they still have mailrooms? I digress.

I can’t claim to know what it is to be schizophrenic or schizoaffective, but I’ve known enough people who have these diagnoses. My brother was one of those. Although I use these and other labels, I am not a fan of labels, generally, especially psychological labels, specifically this label. Autism is another nonsensical label. Both fall into the realm of medical syndromes, which for the uninitiated is the equivalent of your kitchen junk drawer. It’s equivalent to the other choice when all others fail. I don’t want to go off on a tangent from the start, so I’ll leave it that these categories are overly broad and reflect intellectual laziness. There is no single schizophrenia or autism. There are many, but the distinction is lost in the category. The push to create an autism spectrum for DSM obscures the problem, but it helps for insurance purposes. As the saying goes, follow the money and you can gain clues to the driving force behind why this happened. I suppose you can also label me a conspiracy theorist. If I learned one thing in my undergrad Sociology classes, it’s to eschew labels.

Almost finished

Given the length of this segment, I am not going to summarise it here, save to say that this leftward shift in business and culture doesn’t have a good outlook. We are not only being replaced by machines, but we are also forced into becoming machines, and we aren’t even questioning it. All we need to do is to become more analytic, right?

What I suggest is to watch the six-minute video of Dr Iain McGilchrist discussing this topic, and if you really want a deep dive, read The Matter with Things, an almost three-thousand-page tome, to fill in the details.


Here’s a music analogy to help to express why the whole is more important than the sum of the parts. If I want to learn to play a new piece, I will listen to the piece first. Depending on the length and genre, I may have to listen many times. In some cases, once or twice is enough, but let’s say this is at least somewhat complex and not some repetitive three-chord pop song. I’ll probably break the song into pieces or movements—verse, chorus, bridge, and whatever—, and then, I’ll learn each note and each pattern of notes, perhaps as musical phrases. Once I figure out the verse, I might either learn how the next verse differs or move on to the chorus and defer that verse-to-verse step. I’ll rinse and repeat until I’ve got through each of the sections. If I’ve had the luxury of hearing the piece, I’m at an advantage as far as tone, timbre, and dynamics are concerned; otherwise, I’d better hope these are all documented and that I interpret them in the manner they were intended. If the audience is familiar with a tune, they’ll notice the difference.

When I am practising, I need to get the mechanics down pat. All of what I’ve described thus far is left-hemisphere fare. It’s translating the symbolic representation of notes—like letters and words in writing—into an utterance. In this case, it’s a musical utterance. But once I am ready to perform the piece, it needs to be performed through the right hemisphere or it will feel mechanical and stilted.

I used to earn my living as an audio recording engineer and producer. Most of the time I was working with unknown artists recording demo records and trying to get a record deal. For the uninitiated, that usually translated into not having a large recording budget. Occasionally, we want, say string parts—violins, viola, cello, or whatever—but we couldn’t afford union players. We’d hire music students from USC or UCLA. These players would be more than willing to play for cheap in exchange for something to add to their portfolios or experience chops.

Somebody would transcribe the musical notation, and we’d give it to the string player. Of course, it could be a keyboard or wind or reed part, but I’ll stick to strings. Part of music is the vibe. This is something that can’t be captured in symbols. Revisiting Scientism and the left-hemisphere analogy, vibes can’t be real because they can’t be notated.

Almost invariably, if we got someone with Classical training, they could not get the vibe. The music was right in front of them. We’d play it for them on piano, maybe on a synthesiser, but they couldn’t get it—even if they were playing along to a reference track just trying to double the synth part. They would hit every note for the specified duration and dynamic, but it might have as well been the equivalence of a player piano or music box.  We could have played it on a synthesiser, but we might be seeking the nuance a real instrument would bring.

We never had the luxury of auditioning players or recording several players and grabbing the best parts. That’s for the bigger-budget artists who go through a half-dozen or more performers to get just the right one. When we got lucky, it was usually because we got someone from the jazz program. These cats seem to have a natural feel for vibe inaccessible to the classical performers.

In business, the classical performer is good enough, but for art, it wasn’t. Business might appreciate the difference if it happens to get it, but it won’t seek it, and it won’t pay for it. A pet peeve of mine is a quip in business I heard often—don’t let perfection be the enemy of the good. This is obviously a left-hemisphere sentiment based on Voltaire’s statement. Besides, even from a left hemisphere perspective, reciting, “Don’t let perfection be the enemy of the good” doesn’t mean you shouldn’t at least strive for good enough because I noticed that mark was missed often enough, too.

Right Creativity

The struggle is real. Last night, rather about 3 AM, I awakened with a thousand thoughts. This happens often enough. Some were creative ideas. Some were ideas for topics to write about here. Not just topics, but content as well. Then came the internal debate—whether to wake up and capture these ideas or to hope they’d remain in cache until the morning. All I can say it at least this one did. Well, the topic, at least.

The struggle is whether to lose sleep and risk not falling back to sleep to be able to awaken at a decent hour and not be dragging around the next day from lack of sleep. Or perhaps, at next notice, it would just be time to get up. All these scenarios have occurred at one time or another.

I tend to write a lot, whether for here, for work, for pleasure—whatever. I used to create visual art and certainly wrote a lot of songs or at least musical ideas that I hoped would develop into songs. The struggle was the same. The outcomes were as well.

Having read as much as I have of McGilchrist, it starts to make sense. The right cerebral hemisphere is the font of creativity. It’s also the place for intuition and empathy. The left hemisphere is for symbols and categories. It’s the quarter for intellect. It’s also a bad roommate.

Whether or not one is creative does depend on the right hemisphere. Whether one can create depends on the left. Allow me to explain after laying out a relationship and three possibilities. For my purpose here, I can reduce the brain to three principal actors—the right hemisphere, the left hemisphere, and the frontal lobe.

As mentioned already, the right hemisphere generates creativity; the left hemisphere allows these ideas to be articulated symbolically, as in written and spoken words or art or music notation and so on; the frontal lobe acts as a mediator. Without getting too deep into neurology, a primary function of the frontal lobe is restrictive, which is to say it tells one or the other hemisphere to shut up and mind its business. Unfortunately, the hemispheres have this veto power of their own, so it’s difficult to fully understand the dynamics. This being said, let’s have a look at four scenarios that may illustrate why someone may or may not be able to create—in some cases even if they are otherwise creative.

I’ll start with the situation where the right hemisphere generates the creative ideas, and the other actors perform as expected. This is the brain of the creative person.

In the second scenario, the right hemisphere is simply weak. The person was just born with the bad luck of having a hemisphere that isn’t creative. In this case, there is nothing the left hemisphere or frontal lobe can do to compensate for this deficit. I’d like to think—like, perhaps being the wrong word—that this is where most non-creative people reside. They just don’t have that metaphorical creative gene.

In the third scenario, the right hemisphere generates plenty of creative thoughts, but the left hemisphere won’t “shut up”. If you’ve even had to think in a place with a lot of noise or distraction, you’ll get the gist. This is an imperfect analogy because creativity is precisely about not concentrating. Concentration is the enemy of creativity. So, in the case that the left hemisphere is interfering, it’s because it insists on concentrating, and that interrupts the creative process. In fact, it’s a misnomer to call something s creative process because creativity is precisely a lack of process. Like concentration, process kills creativity.

The right hemisphere is open and divergent.
The left hemisphere is closed and convergent.

In the fourth and last scenario, the right and left hemispheres are each playing their parts swimmingly, but the frontal lobe as moderator is deficient. In this case, the left is being itself and disrupting. Like the parable of the scorpion and the frog, it can’t help itself, but the frontal lobe isn’t telling it to be quiet and wait its turn. That’s the job of the frontal lobe. If you’ve ever witnessed a debate or mediated discussion where the moderator just lets the participants run rampant, you’ll know what I mean. Or perhaps you’ve been in a classroom or a meeting where the teacher or leader has no control of the class or the audience. It’s difficult to get anything accomplished.

Moving on. So, the actors each have their roles, but timing matters. The right hemisphere not only needs to generate thoughts or ideas, but it also needs time for them to incubate. Once they are ripe, only then is it ready to encounter the scrutiny of the left hemisphere and seek moderation for the frontal lobe.

If during the incubation process, the left hemisphere is continually asking, “Are we there yet? Are we there yet?” it’s unlikely one will ever get there.

If you are wondering how this works in the world of business and commerce—or better yet, you have already put together that this can’t possibly work in the realm of business and commerce—, I talk about that next. And I’ve got another segment on cerebral challenges in business in the works.

Creativity cannot be time-boxed. It can’t be summoned on demand. As already mentioned, it is not a process, and it can’t be tamed. Aside from the fickle public, have you ever wondered why so many musical artists are one-hit-wonders—if they have even been that lucky? These people had one idea—that happened to be an idea that would resonate in that moment—, but being told by the label to go generate some more hits is asking for creativity on demand.

Depending on your age and generation, some of you might be asking yourselves, “What about Taylor Swift or Ed Sheeran or the Beatles or Beethoven?” These people are clearly the exceptions. We could as well look at the Vincent van Gough of the world who didn’t experience acceptance until after his death. Clearly, his creativity was unrecognised by his contemporaries. Even in some of these exceptional cases, these people have found a voice and are applying a pattern. An example I like is that of Stephen King, who in an interview admitted that he has only had one good idea in his entire life, and he’s exploited it into a large number of books. So, he’s kept reskinning the same skeleton but with different dressings.

And as far as commerce goes, yes, these people are commercially successful. Some would argue about the actual talent. I’ve seen philosophy classes compare the ‘high art’ of Shakespeare with the ‘low art’ of Matt Groening’s The Simpsons. Certainly, The Simpsons are culturally creative and commercially successful, but how creative is it really? How does one actually measure degrees of creativity?

My point is that these exceptional people are generating output once a year or every few years. In business, so-called creatives may be asked to generate new ‘creative’ content daily, weekly, or perhaps monthly. Creativity doesn’t work like this. Even if you asked Mozart to generate a new piece each week, this mechanical process might yield paydirt, but most would just be a formulaic rehash. In fact, if you talk to any top artist, they’ll tell you that what you see or hear is less than one per cent of their ideas. Most are either partially formed or, upon reflection, just bad. They felt good at the time, but they couldn’t develop into something better, or they turned out to be derivative, which is hardly creative.

So business is a death sentence for creativity. The creative people I know, don’t get their creative jollies from their day jobs. They get it from their side projects, from their passion projects, and whether or not these projects are commercially viable.

In fact, I can also look at someone like Nirvana’s Kurt Cobain who was creative at the start—when they were under the radar—, but once they rose into view, he lost it, and then we lost him.

I hope this gives you a better feeling of how creativity works from the perspective of the brain and why we see so little creativity in the real world and even less in the business world. Do you find this surprising, or are you thinking, “man, this bloke must be dense if he’s just catching on to this now”?

Let me know in the comments.

The Matter with Things: Chapter Seven Summary: Cognitive Intelligence

Index and table of contents

Following Emotional and Social Intelligence and the rest, Chapter 7 of The Matter with Things is Cognitive Intelligence.

In the last chapter, we learned that Emotional and Social Intelligence are the provinces of the right hemisphere. In this chapter, we discover more of the same. Whilst the left hemisphere has its duties and functions, it’s primarily a delegate. Let’s jump right in.

Podcast: Audio rendition of this page content

Under the old pseudoscientific mode of thinking, the left hemisphere was the logical side whilst the right hemisphere was creative. It turns out that this is not correct.  At its core, intelligence is about understanding. Keep in mind that there are multiple kinds of intelligence—not referring to multiple intelligence theory, per se. Besides the emotional and social sort discussed at length in the last chapter, there is a sort of rote intelligence. This is where the left hemisphere excels. The left hemisphere is symbolic and algorithmic. It has facilitated the making of computers and other instruments that allow us to extend our intelligence, but these are not sources of intelligence. In a conceit to his previous book, The Master and His Emissary, McGilchrist notes that the left brain is effectively the emissary, the junior partner in the relationship, and not really even a partner as the right hemisphere seems to call all the shots when it’s intact.

He tells a story about a geneticist who declared to a biologist that the notion of intelligence was quite meaningless. The biologist retorted that he (the geneticist) was unintelligent, and the two never spoke again. Clearly, the notion is that whilst it may be ill-defined, it nonetheless contains meaning.

I share the working definition of intelligence that he shared, taken from the journal Intelligence and cited in the Wall Street Journal in 1994.

Intelligence is a very general mental capacity which, among other things, involves the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly and learn from experience. It is not merely book learning, a narrow academic skill, or test taking smarts. Rather, it reflects a broader and deeper capability for comprehending our surroundings – ‘catching on’, ‘making sense’ of things, or ‘figuring out’ what to do.

As noted, there are several flavours of intelligence, even if they are attempted to be captured as G, general intelligence. This can be separated into crystallised intelligence (Gc) and fluid intelligence (Gf). Crystallised intelligence is more culturally bound than fluid intelligence and is more the domain of the left hemisphere. Generally, this is what IQ tests aim to measure.

Two criticisms of IQ tests are the cultural bias and the rote nature of the tests. As it happens, trends show that IQ is generally on the rise despite a feeling that people are getting dimmer. This may be because this rise represents the shift toward left hemisphere thinking, an alarming topic he’ll cover more in future chapters. We’re witnessing a trade-off between creative thinkers for intelligent rote automatons—the type of people more easily supplanted by computers and automation. Even as IQs are apparently increasing, undergraduate professors are complaining in higher numbers about how unprepared their incoming students are. I can add my experience anecdotally to this list. I recall chatting with a physics professor who complained that he had to devote some 20 per cent of his class time to teach students the same prerequisite maths, which meant that he had to cut this from his intended time to teach physics.

As a student, one of my physics teachers said he wouldn’t demerit much for maths errors because this was, after all, a physics course. Again, this was a reaction to many students not being prepared. They just had different approaches to handling the deficits. And don’t get me started on grade inflation.

The right hemisphere is the realm of fluid intelligence and is activated more in gifted persons. This affords creative problem-solving.

The right hemisphere is the realm of fluid intelligence and is activated more in gifted persons. This affords creative problem-solving.

Let me editorialise here in place. Sometimes we hear that this or that person is good at maths, but it turns out that this is not a simple declaration. A person who studies geometry, trigonometry, and calculus and can perform the functions may simply perform all of this rote activity in the left hemisphere. Because someone can do maths a few levels above us may feel like this person is good at maths, but this may not make this person actually good at maths.

A few years ago, I read the introduction to a book whose title I’ve long forgotten. In this introduction, the author had excelled at left hemisphere maths and got his bachelor’s and master’s degrees in mathematics. Whilst pondering whether to pursue a PhD, in a moment of self-reflection, he decided not to. He was an A student and the pride of his family, but he had to work hard at maths. Then he considered some of the other classmates who seemed to perform the tasks effortlessly. He could do maths, but they could think maths.

This reminds me of the story of a young Carl Gauss whilst he was still in elementary school. Don’t worry. I’ll get back to the summary presently. Gauss’ teacher was hoping to keep the students occupied, so he assigned them the task of summing the numbers 1 through 100.

Eight-year-old Gauss considered the problem. He noticed a pattern and worked out the answer in his head after a few seconds—5050. Gauss excelled at maths naturally. He noticed that pairing each ascending integer from 0 to 100 created values of 100; 1 and 99; 2 and 98, 3 and 97 … 49 and 51. There are 50 such groupings with a product of 5,000 and 50 left over, so 5,050. Easy Peezy.

And now we return to regularly scheduled programming.

Another interesting characteristic of the hemispheres is that the left hemisphere operates serially whilst the right hemisphere operates in parallel, metaphorically speaking, of course. The right hemisphere is the Gestalt operator, which is a problem as McGilchrist sees it given the leftward shift in the sciences, losing the woods for the trees. Moreover, as we are forced into the constraints of business and bureaucracies, we are forced into a left hemisphere perspective, which may create a vicious epigenetic cycle or a downward spiral.


In summary, the right hemisphere not only contributes to the majority of emotional and social intelligence as discussed in the last chapter, but it is also the workhorse of cognitive power.

Before ending, I want to share one more elucidation. I was reading elsewhere about critical thinking, and an example given was an emergency room nurse triaging patients—prioritising the treatment of patients. I wholly disagree. This is algorithmic thinking, not critical thinking. It could easily be done by a computer. In fact, in the late 1980s, I was working with so-called expert systems, which were the AI hype of the day in wave 3.0. We are now in wave 4.0 and it is still hype. Only nowadays it’s deep learning, machine learning, visual recognition, edge computing, and robotic process automation. The only difference is that technology has driven costs down, so they are more accessible to more people and can be run on more powerful computers. For the uninitiated, there is no intelligence in artificial intelligence. So, it’s less artificial and more non-existent.

Yet again, I am left wondering what this left hemisphere is good for.  It seems to do less than 20 per cent of the work and does half of that poorly. Not exactly someone you’d pick for your team. Of course, I wouldn’t want to sacrifice my left hemisphere, but still.

That about wraps up the chapter on Cognitive Intelligence. Next up is chapter eight on Creativity. If you think this will focus more on the right hemisphere, I’ll bet you’re right. I hope you’ll join me.

What are your thoughts on intelligence and the hemispheres’ split duties? Did anything surprise you? Was there anything of particular interest?

Bird Brain

In English, bird brain is a pejorative. The top Google search result yields a definition of ‘an annoyingly stupid and shallow person.’ Nonetheless, bird brains and human brains have many similarities. They have structurally divided, bi-hemispheric brains and lateralisation of functions, just like us and most other vertebrates, but how they differ is more interesting.

I’ve extracted the majority of information on this page from Iain McGilchrist’s publication The Master and His Emissary with a focus on birds.

Firstly, except for birds of prey—because they have forward-facing eyes—, birds don’t have stereoscopic vision. If you’ve ever noticed a pigeon or a chicken strutting about, they jerk their heads around. This is to render a better perspective of their immediate surroundings.

Recall that the left hemisphere is about contraction and closure. The right hemisphere is open and expansive.

For birds, there is a need to focus attention narrowly and with precision, for example, on a grain of corn. At the same time, there is a need for open attention to guard against a possible predator. But apart from the optical mechanisms involved, there is the cognitive need to focus attention, but it is an impossibility to focus on both simultaneously. There is a trade-off between close focus and wide focus. To do both is to do both poorly. The trade-off is to eat or be eaten, so this is a nontrivial conundrum.

You can simulate this yourself. Out of doors or in a large-enough indoor space, hold a page at arms’ length and try to read the words on the page and keep the background in focus.

Returning to the birds and remembering that, like us, the left eye is controlled by the right hemisphere and the right eye is controlled by the left. You should suss out by now that this translates into the right eye for getting and feeding and the left eye for environmental vigilance.

Although they are better at detecting predators with the left eye, many types of birds show more alarm behaviour when viewing them with this eye. If they detect a predator with their right eye, they will also choose to re-examine it with their left eye to the extent that they will turn their head to make the visual connexion.

Like humans, chicks preferentially use the left eye (right hemisphere) for gathering social information.

Like humans, chicks preferentially use the left eye (right hemisphere) for gathering social information. They use this eye to differentiate familiar members of the species from one another and from those who are not familiar. Some species seem to operate opposite to this, but they are the exception.

One interesting bird of note is the wry-billed plover of New Zealand. With a beak that curves to the right, it favours the left hemisphere for focusing on feeding.

McGilchrist notes that “there is a strong right eye (left hemisphere) bias for tool manufacture in crows, even where using the right eye makes the task more difficult”.

Another feature in common between humans and birds is speech vocalisation as it were. In both cases, speech articulation is the domain of the left hemisphere.

The right hemisphere in birds, as in humans, is associated with detailed discrimination and with topography; while the left hemisphere of many vertebrate animals, again as in humans, is specialised in categorisation of stimuli and fine control of motor response.”

The right hemisphere yields broad, vigilant attention, and it is involved in bonding in social animals.

In general terms, the left hemisphere yields narrow, focused attention, mainly for the purpose of getting and feeding. The right hemisphere yields broad, vigilant attention, and it is involved in bonding in social animals.

The right hemisphere underwrites breadth and flexibility of attention, where the left hemisphere brings to bear focussed attention. This has the related consequence that the right hemisphere sees things whole, and in their context, where the left hemisphere sees things abstracted from context, and broken into parts, from which it then reconstructs a ‘whole’: something very different.

Left-Brain, Right-Brain

The hemispheres of the brain have functional differences. I created a short-form video on YouTube, so it’s less than 60 seconds.


If you see a face in this image (in the accompanying video), you can thank the right hemisphere of your brain. The right hemisphere is about unity and the whole—a Gestalt. It fills in missing pieces to construct a whole. And it’s usually pretty good at it.

Think of the right hemisphere as Zen. It’s about experiencing the world as presented. It experiences the world without judgment, without attachment, without naming. It’s about openness and options.
The left hemisphere is about division and parts. Where the right hemisphere wants to open up, the left wants to close down. And it’s about creating maps and symbols, then re-presenting these.
Where the left hemisphere of the brain is focused on the trees, the right hemisphere sees the forest or the woods.

The left hemisphere is what creates our sense of self and individuality whilst it would probably not be unfair to characterise the right hemisphere as the Buddhist notion of selflessness and an undivided universe, where ‘self’ is an illusion.
The left hemisphere is literal whilst the right is metaphoric. It is also the realm of poetry and empathy.

Cerebral Hemisphere Differences: Woods and Trees

Iain McGilchrist feels that the world is moving too much toward a left hemisphere-dominated world. This has happened before, ebbing and flowing, and perhaps it will change direction again at some point. Although this compartmentalised thinking has its roots at the beginning of the Age of Enlightenment, it has accelerated in the past century as specialisation has too many of us losing the woods for the trees.

Humans have “a sufficiently strong propensity not only to make divisions in knowledge where there are none in nature, and then to impose the divisions on nature, making the reality thus conformable to the idea, but to go further, and to convert the generalisations made from observation into positive entities, permitting for the future these artificial creations to tyrannise over the understanding.”

— Henry Maudsley, The Physiology and Pathology of the Mind,1867

I hope McGilchrist explores extreme right hemisphere dominance more in The Master and His Emissary, whether relatively due to a deficient left hemisphere or because of the right hemisphere running amok.

McGilchrist warns the reader time and again that both hemispheres are involved in many activities, and it is what they are doing or how they are processing the events that differ. But when we generalise some primary competencies—a decidedly left hemisphere activity—, we notice that the left hemisphere is about constrained thinking with a focus on elements rather than the whole as illustrated previously and creating a map to re-present those data.

A Woman’s Face in the Trees: Gestalt in Action

Conversely, the right hemisphere is about openness and experiencing the world as it is presented rather than a re-presentation. I likened this to a Zen approach. It would probably not be unfair to relate this to the Buddhist notion of oneness and selflessness.

Given Iain’s assessment, perhaps right hemisphere dominance is not our biggest concern at the moment. However, I perceive a potential problem. Given the right hemisphere’s proclivity toward Gestalt, I am concerned that it also overgeneralises things into a whole where they shouldn’t be connected, as such. Gestalt is what fills in spaces in perception to make it appear as a whole. I’ll consider this to be an interpolation. But if it interpolates wrong, we may incur fitness penalties. Aside from this, I consider extrapolation—or perhaps misidentified boundary states, which is to say we include aspects outside of the ‘real’ domain boundary and glom it onto the model because, cognitively speaking, we don’t know what to do with it or how to interpret it. Once it gets passed to the left hemisphere, it (incorrectly) codifies it, from that point onward being mis-re-presented.

So where the left hemisphere loses the woods for the trees, the right hemisphere annexes the neighbours’ woods.

Cerebral Hemisphere Differences: Pattern Definition

Continuing with a quick post based on observations in The Master and the Emissary by Iain McGilchrist, another example of hemispheral specialisation is illustrated in the image below.

A typical person will envisage this large S composited with smaller Ss (that could be replaced with any symbols, so there is nothing special about the S comprised of Ss) as represented by the centre image of the rendition of the bilateral interpretations.

Where there is left hemisphere damage, the right would envisage something more like the S on the right—seeing the big picture but losing detail. Where there is right hemisphere damage, the left would perceive something more like the S on the left, which is the detail of the composite Ss without recognising that they composed a bigger picture. This is conveyed in the aphorism of losing the woods for the trees whilst the former right hemisphere dominant view might not realise that the forest has trees.

But even this misses the point slightly because if you are viewing this as a typical person, you can assemble the Ss on the left and realise that it makes a larger S whereas a person with right hemisphere damage will just see a mass of Ss and not see the larger S shape. Moreover, it’s not that the right hemisphere wouldn’t ‘see’ the smaller composite Ss, it just wouldn’t put any significance on them, thus ignoring them and considering them to be background noise.

I really do want to share about the non-stereoscopic animals as well as another instalment from The Matter with Things. At least one of these is probable for the next post.
