Can we figure out what information is by looking at how information is held in brains, computers and bee hives?

I’ve been perplexed for a long time by what information really is. We often hear that the brain holds information. How is this so? The gist, as I understand it, is that information comes into our brains via the senses and these “bits” of sensory information are held in the activation of neurons. So, as a child I might have petted a cat and that sensory experience was encoded in my brain. Later, a cat scratched me and that experience was also encoded. Numerous similar experiences occurred (as well as more formal booklearning about cats) and now when I think of cats, all these encoded sensory experiences activate to various degrees and as a result I have information about what a cat is.

Part of the gist there is that I need consciousness to experience sensory input and therefore consciousness is (probably) necessary for information to exist (if “exist” is even the right term.)

Now think of computers. They too hold information (or so we are told.) Information in computers is held in on/off switches which are transistors with electrons running through them. But where is the consciousness? I think they general consensus is “nowhere.” The information in a computer is meaningless until a conscious mind observes it. (Bringing to mind the old “tree/forest” koan.)

And yet, people talk about artificial intelligence gaining consciousness.

Both brains and computers are networks in the sense that they are interconnected nodes. The basic node of the brain is the neuron and the basic node of the computer is the transistor (though it could be anything that can be in an on/off state.) But, again, computers don’t really “know” the information they hold (because they are not conscious.)

Bee hives and ant colonies are also networks and the basic nodes are the individual bees or ants. And hives and colonies seems to “know” information that the individual nodes can’t know (like how to work together to build a bee hive). They can even perform calculations.

So where is this information held? Is there a meta consciousness that must exist to appreciate the information held in the connecting nodes (ants and bees)? Or are they more like computers? Dumb nodes with no self awareness? (I’m aware ant and bees probably have some kind of consciousness but not necessarily the amount needed to appreciate the information they collectively hold.)

(Part of the answer to these question may be found here:
The Remarkable Self-Organization of Ants)

I find myself wondering if information even exists at all.

Data as music

I stumbled across an interesting article discussing how scientists are rendering data in musical form. This, apparently, allows them to sense patterns in the data they might otherwise be unaware of.

Scientists can listen to proteins by turning data into music

Transforming data about the structure of proteins into melodies gives scientists a completely new way of analyzing the molecules that could reveal new insights into how they work — by listening to them. A new study published in the journal Heliyon shows how musical sounds can help scientists analyze data using their ears instead of their eyes.

The researchers, from the University of Tampere in Finland, Eastern Washington University in the US and the Francis Crick Institute in the UK, believe their technique could help scientists identify anomalies in proteins more easily.

“We are confident that people will eventually listen to data and draw important information from the experiences,” commented Dr. Jonathan Middleton, a composer and music scholar who is based at Eastern Washington University and in residence at the University of Tampere. “The ears might detect more than the eyes, and if the ears are doing some of the work, then the eyes will be free to look at other things.”

If you don’t fully comprehend what this all means, well, I’m right there with you. But one can easily envision a way that different values of data could be thought of as steps away from a average value, and those steps could be represented as a musical scale. So really large musical leaps would indicate major deviations from an average.

And here’s another article also about data being transformed into music. I guess this is a “thing.”

Detecting patterns in neuronal dendrite spines by translating them into music

There’s some example of this “dendritic spines as sound” music here and it’s pretty unappealing. (Part of the problem is that it’s rendered with hideous midi instrumentation.)

Taking seriously the possibility of multiple consciousnesses

Years ago I posted a blog posted asking whether we have multiple consciousnesses in our heads. I described the basic concept thusly:

A while back I was considering an idea for a fiction character. The conceit was that the character had multiple consciousnesses in their brain, but each consciousness generally arrived at the same decisions. So, if this person received an coffee from a waitress, one consciousness might think, “Wow, she sure brought the coffee fast, I better thank her,” while another consciousness might think, “Look at this whore. I bet she thinks by bringing me coffee quickly she’ll get a tip! Oh, well, I better thank her in the interests of conforming to society. Bleg.” In addition, neither consciousness was aware of the other.

I was, frankly, only half serious. But I’ve been reading Sam Harris’s recent book, “Waking Up,” and he takes the possibility seriously. Referring to the famous split brain experiments, he throws out the possibility of one consciousness in the right brain and one in the left. He even addresses an obvious problem: if we have multiple consciousness, how do they avoid conflict with each other (especially if they aren’t even aware of each other)? The answer is found in the theory of a philosopher quoted in the book.

The non-speaking hemisphere has known about the true state of affairs from a very tender age. It has known this because beginning at age two or three it heard speech emanating from the common body that, as language development on the left proceeded, became too complex grammatically and syntactically for it to believe it was generating… Being inured to this status of cerebral helot, it goes along. Thankless cooperation becomes a way of life.”

The idea is that you have this other consciousness sort of enslaved to “your” consciousness. It is so used to being powerless that it goes along with the dominant self.

Of course Freud’s theories were all about inner conflict. Perhaps that conflict is between these two consciousnesses.

And, I believe Harris leaves open the possibility of even more consciousnesses within one brain. What a trip that would be.

UPDATE: I feel I should clarify one thing here. In the case of the split brain patients, each hemisphere has been separated from the other and the patients seem to behave as if they are two selves in one body. Us normal folks have connections between the two hemispheres and most of us behave as one self. But Harris argues that the connecting tissue can’t possibly pass all the information in one hemisphere to the other, so were are really more like two selves that have some limited communication with each other.

Finding patterns in music

A while back, I linked to this page on, among other things, sound waves and how they relate to music. If you scroll down to the section titled “Musical Beats and Intervals” you see three diagrams showing three different pairs of overlaid wave forms. One is a very consonant octave set (something like a low C played over a high C), one is a relatively consonant 5th interval and the final one is a dissonant, ugly sounding interval. The point these diagrams make is that consonance and dissonance are not abstract properties of music, they are related to how two or more sound waves overlay on top of each other. Waves where the peaks and valleys generally line up sound good; waves where the peaks and valleys don’t consistently line up are weird.

The same is true with rhythms. If I take a drum groove played at 100 beats per minute and lay it on top of a drum groove at 200 beats per minute, everything should sound all right since the hits in the 100 beats per minute groove will correspond with every other hit in the 200 beats per minute groove. But if I overlay a groove at 157 beats per minute over a groove at 100, not much will line up and it will sound chaotic.

Now, this is no different in the first example using notes. Notes are really sound waves vibrating at certain frequencies. You could think of the peaks of sound waves as the “hits” in a drum rhythm. If you take two sound waves and the peaks line up most of the time you have something consonant. But the less they line up, the more dissonant they get.

So basically, when you hear consonant sound waves (or drum rhythms) your brain is comparing the peaks or hits and determining that they match and delivering a pleasant sound to your mind. But this comparison, this brain processing, is something we are unaware of. With two dissonant notes, we aren’t aware that the sound wave frequency rates are out of sync, we are just aware they sound bad.

And I suspect this is true with a lot of things. Our brain looks for patterns, for synchronicity. When it finds the pattern, it says, “yay, I like this.” When it doesn’t find the pattern it gets frustrated. But much of this processing goes on “under the hood;” we aren’t consciously aware we are doing it.

Playing “The Game”

I recently picked up a booked called “The Game.” It’s a memoir of the author’s time spent as part of a particular group of pick up artists who slept with hundreds of women while operating primarily in LA, but also New York, Miami, and various other cultural hot spots.

This might sound like a departure from my usual reading material which tends towards neuroscience, psychology and philosophy. In fact it fits right in there. What these guys were doing was using a deep study of theories rooted in various psychology paradigms—particularly evolutionary psychology—to “game women. And it seemed to have worked quite well, though the toll the endless pursuit of dames takes is starting to show by the chapter of the book I am at.

In general, a pick up artist presumes that there are rules to how the mind works and these rules can be gamed to lure a prospective partner into bed. And the rules aren’t what conventional wisdom would argue. The official rulebook on romance says a man earns a woman’s affection by being kind and buying her flowers etc. “The Game” argues you do it by “negging” them (neg = a kind of light hearted diss), appearing disinterested, peacocking (dressing outlandishly) and creating a “yes chain” (basically asking a bunch of questions where the answer is yes in order to get the gal used to saying yes to whatever you propose.)

None of this is really news. We’ve all heard the complaint that women really like jerks. Pick up artists just make a point of being (somewhat likable) jerks.

I think there are some caveats to all this. These techniques probably work best on women of a certain age who want to experience the wild side of life but maybe don’t want to admit this to themselves. And there’s also, as the author admits, a “play the numbers” element to it. Guys who hit on lots of women with these techniques are bound to catch a few. That said, I believe the techniques make a difference; it’s not merely a numbers games. I say that partly because I did have period of some success with women (after years of failure) and I did some of the stuff mentioned in the book, albeit on a limited level. (When I read the section of peacocking I was reminded of a girl who told me she’d only gone out with me because she liked my glasses. At the time I had a pair of stylish, black rimmed glassed that had been picked out by an ex-girlfriend and replaced the hideous, dorky glasses I wore through my mostly celibate 20s. I’m convinced that original pair was a women-repellant.)

As I read through the book, its ideas seem familiar. And that’s because this is exactly the kind of stuff Scott Adams says Donald Trump is doing: using subtle cues to “persuade” people to support him. Adams himself often mentions Neuro-Linguistic Programming (NLP) in relation to this kind of persuasion. NLP is (probably) a pseudoscience* that studies how to subconsciously get people to do what you want. It gets mentioned a lot in relation to sales and negotiation. And NLP is touted by all the pick up artists in the book. (After all, picking up women is all about sales and negotiation.)

* Like all pseudosciences, however, there’s some truth to it.

It all points to rather dismal news. The way to get political power is not by being a standup individual, it’s by brainwashing people into supporting you. The way to satisfy your sex drive and its desire for variety is by tricking cosmo-guzzling 22 year olds into sleeping with you. Honesty and integrity have no place in these realms.

But that’s not really news, is it?

Collective humans

I was strolling through the shelves of the library the other day and picked out a book titled “Global Brain” by Howard Bloom. The book’s premise—one I’ve heard before—is that individual life forms, whether they be bacteria or human, thrive by forming groups. All creatures, the book would seem to argue, are essentially social creatures. Hive or colony type creatures, like bees and ants, are especially demonstrative of this fact; they accomplish far more as a giant organism of many nodes (the individual bees and ants) than they would if they were all living separate lives.

This is true for humans as well. On one level, humans exist in societies. These societies seems to have a kind of meta-intelligence that decides to move towards democratic governments or embrace Justin Bieber. (Hmmm…) On another level, each human is really a collection of trillions of cells. Just as the decisions of a society emerge from the choices of individual humans, so to do the decisions of human individuals emerge from a chorus of cells. Your wants and needs and opinions are really the result of millions (or more) of votes. (At least this is what I think the book is gearing up to argue, as others have before. I’m only about five chapters in.)

This idea, that we as individuals are the result of many, seems both exciting and disconcerting. I don’t feel like a group, I feel like an individual. But we do have a certain sense of our compartmentalization. I say, “my stomach is telling me I’m hungry.” “My hand is tired after thumb wrestling for hours.” “My penis is aroused as it watches this naked woman walk by.” (A regular occurrence in my life.) The “I” that is the storyteller of our lives is being informed by other parts of the body. And even if we observe just the brain/mind, we can suss out how information kind of rises up to our top decision maker. We’re thinking of a way to solve a problem and the answer just arrives in a Eureka moment. Because a coterie of cells beneath our consciousness have been working at the problem and have arrived at an answer.

In theory, you could have some complex network of nodes, doing all sorts of calculations, without consciousness. That’s basically what we presume a computer to be doing: thinking (in a way) without being aware of it. But we humans have consciousness riding atop all this. Attention is a big part of it. When we are hungry our attention turns to our hunger. When we are horny our attention turns to our horniness. The conscious attention is what makes us feel like an individual as opposed to a million voters.

Which leads to that most perplexing of questions: what is consciousness?

Democracy blows

As I’ve mentioned many times now, Scott Adams has been making the argument that Donald Trump’s un-anticipated (and controversial) political rise occurred because he is great at the art of persuasion. And persuasion, according to Adams, is not a matter of appealing to reason and logic but rather the emotional brain and people’s sense of identity.

Adams further notes, as does common sense, that Trump is not the only politician to do this. All, to varying degrees, use this kind of persuasion to get elected.

Now, that argument really needs to be unpacked and examined before we can sign off on it. But I’ll say here that it at least feels right. Most political debates don’t have the feel of people arguing about math, they have a great deal of emotional element.

If Adams is right, does this not point to a deep flaw in democracy? Democracy is based on a kind of “wisdom of the masses,” but if the masses are easily manipulated dum-dums, should we not consider a different form of government?

Now, of course, “what is the best form of government?” is a question humanity has sought to answer for centuries and every system of government has had flaws. Monarchy is ok until you get a idiot king. Oligarchy has similar problems. I don’t really know the answer here but I start to find myself suspicious of the ‘rah-rah” approach most take to democracy, as if it’s clearly the superior system.

There’s a point madde in the book “Soul Machine” that ties into this. The author notes that “Locke’s tabula rasa gave philosophical and scientific standing to Thomas Jefferson’s proclamation that “all men are created equal.”” John Locke had argued that people are born as a blank slate and how they developed was determined by their environment. Put a kid in the right environment and he could be a genius scientist, put him in the wrong environment and he becomes a dull-witted criminal. But at the start, everyone has equal talents.

Now, two and a half centuries after Jefferson’s pronouncement, we know that genes do have some affect on people’s abilities. People are not created equal, some are intrinsically smarter, or more empathic, or intuitive than others. Thus a cornerstone for Jefferson’s case for democracy has fallen.

Francis Hutchenson on morality

Not long ago, in an article entitled “What is Morality,” I offered up the argument (not original to me) that moral behavior is built into our brains via evolution. I noted…

We want to believe that by being moral we are following a set of rules — perhaps divine rules, or perhaps rules dictated by some kind of universal logic. But I am saying morality is neither divine nor logical; moral rules are simply the rules of socialization that have evolved through the history of our species. Our brain applies these rules, much the same way it applies rules for emotions. When we are contemplating or performing an immoral action, we are prodded with a sting of discomfort, similar to the sting of fear. When we are contemplating or performing a moral action, we get a “good feeling,” similar to joy or pride.

The idea being that we literally sense which behaviors feel good and which feel bad. At the time I thought this was a fascinating development in moral psychology. But, while reading the book “Soul Machine,” a history of the development of the concept of the mind, I find…

Hutchenson accepted Locke’s argument that sensations created ideas which then furnished the mind, but he also believed with Shaftsbury that an innate moral sense was the primary motivation for humans, and the source of their emotions. Sentiments arose from that moral barometer—joy from acts of charity and remorse from deceit. Through this moral sense, we experienced another’s emotional state deeply and directly. Ethics and social stability rested, not on the Good Book, but on this natural state of shared compassion, what he called “sympathy” between human beings. Like muscles in the body, this shared emotion balanced private desires and yielded both personal and social harmony.

This Hutchenson fellow basically nailed the idea back in the early 1700s. Interestingly, his idea of experiencing others’ emotional states ties into the the recent, still somewhat controversial, discovery of mirror neurons.

The general sense I get with this book is that all the great philosophical thoughts were thunk centuries ago. Now people are just arguing around the edges.

Decartes’ Error and Donald Trump

I continue my mental exploration of the idea that Donald Trump is a master persuader who is using brilliant tactics to convince a needed segment of the population to grant him the Republican nomination (and eventually the presidency.) I’ve mentioned that Scott Adams has been talking a lot about this idea but so have many people interested in the science of persuasion.

It strikes me that this ties in with a book I often talk about: “Descartes’ Error” by neuroscientist Antonio Damasio. I’ll quote a description of one relevant point of the book:

A few years ago, neuroscientist Antonio Damasio made a groundbreaking discovery. He studied people with damage in the part of the brain where emotions are generated. He found that they seemed normal, except that they were not able to feel emotions. But they all had something peculiar in common: they couldn’t make decisions. They could describe what they should be doing in logical terms, yet they found it very difficult to make even simple decisions, such as what to eat. Many decisions have pros and cons on both sides—shall I have the chicken or the turkey? With no rational way to decide, these test subjects were unable to arrive at a decision.

The article continues…

This finding has enormous implications for negotiation professionals. People who believe they can build a case for their side using reason are doomed to be poor negotiators, because they don’t understand the real factors that are driving the other party to come to a decision. Those who base their negotiation strategy on logic end up relying on assumptions, guesses, and opinions. If my side of the argument is logical, they figure, then the other side can’t argue with it and is bound to come around to my way of thinking. The problem is, you can’t assume that the other party will see things your way.

This describes some people’s frustrations with followers of Donald Trump, doesn’t it? Detractors of Trump don’t get how he can blatantly lie and exaggerate and still have fans. But, if you allow that people are not rational decision makers, but rather emotional ones, then the facts (or un-facts) Trump uses are not the relevant factor. Rather it’s the emotions he generates in his audiences.

As I’ve said before, if this is really true—that people are not swayed by facts—then democracy itself is a joke or at least can be manipulated to rather unpleasant outcomes. I return again to the idea that we should nominate a philosopher king to make society’s decisions. I humbly offer myself.

More on Trump the persuader

I still find myself fascinated by Scott Adam’s arguments that Donald Trump, in his attempt to become President, is employing persuasion techniques used by master salespeople and politicians. To quote Adams

As far as I can tell, Trump’s “crazy talk” is always in the correct direction for a skilled persuader. When Trump sets an “anchor” in your mind, it is never random. And it seems to work every time.

(“Anchors” are a particular kind of persuasion technique. See a description here.)

I’m finding that Adams is not the only one making these claims. For instance, here is an article that goes into the subject of what are called triggers. These are essentially switches in the mind that activate specific emotional responses. Once the trigger has been switched, the theory goes, a person’s decision has been made. Any reasons provided for the decision are merely rationalizations to support the emotional decision.

Trump is activating what in neurological terms are referred to as emotional triggers, which the brain uses to avoid the energy and difficulty of analytical thinking. Whether consciously or by instinct, great persuaders tap into the functions of the emotional brain, where decisions are made with great speed and intensity.

One especially potent emotional trigger Donald Trump is clearly activating in the limbic brains of his most ardent supporters is the contrast trigger. Sales and marketing people know the contrast trigger well enough. They use it to varying degrees of success all the time. Differentiation is a well-worn corporate branding trope used to emphasize the importance of distinction — of being different from the other brand or product.

Do I buy this concept? Not entirely, I think the mind is messier and more complex. But I will say that the idea of triggers corresponds to a lot of what neuroscience and psychology have observed in the past 30 years (particularly in the work described in Antonio Damasio’s book “Descartes’ Error.”)

Also, keep in mind that these persuasion techniques doesn’t have to have 100% successful to be worth using. A persuasive car salesman doesn’t have to convince everyone who comes on the lot to buy a car, just many people. Trump doesn’t have to convince all voters that’s he’s the best choice, just slightly over 50%.

Another assertion from Adams is that when Trump makes outrageous statements, he is doing so intentionally to capture the public and media’s attention. I see here that even Mario Rubio is wising up to this.

“Look, this is a pattern. This is a game he plays. He says something that’s edgy and outrageous and then the media flocks and covers that and then no one else can get any coverage on anything else,” Rubio said.

Related to all this: here’s an article that argues that Trump is using extreme statements to cover up his liberal past.

The thought of a world in which Donald Trump is president feels more like an apocalyptic nightmare to most reasonable Americans. His bigoted statements regarding Mexican immigrants and Muslims, as well as his hotheaded temper, make him appear especially dangerous for international relations. But given certain evidence, one must wonder whether some of Trump’s behavior is part of a strange but strategic charade designed only to win him the Republican nomination.

I have some complaints about that article but it does correspond to my sense that Trump himself doesn’t believe some of his own touted opinions.

I will say, this argument—that we are not really rational in our own decisions—“feels” right to me and I find evidence in myself all the time. I’m finding myself analyzing everything from why I like the politicians that I do to why I buy a certain brand of beef jerky and I have a hard time coming up with really solid, logical reasons. What I experience is more in the vein of gut reactions that I then have to qualify. Adams blogs on this topic have really got me noticing this.

On a final note: I recognize that Adam’s has planted this idea in my head (an anchor) that Trump is a master persuader. Is that why I take notice whenever I see articles like the ones above that support this notion?
