Life logging and loosing yourself
May 2, 2010
In response to a couple of recent pieces on identity by Jeff Jarvis and one by Gary Wolfe of Wired on living by numbers.
It should be becoming obvious by now that I’m quite pragmatic about technologies, especially those that purport to replace mind function with mathematics, and these two threads are kind of along the same lines. Interesting, but not quite right. In fact Wolfe’s piece is quite wrong in some ways, but typical of the cyber-utopian and really getting very dull these days. We’ve had the net 20 years and its still a shiny box to be prayed to for some people. Get over it Wolfe and actually think about what you are saying ! Your words are more important than the technology.
Case in point; Wolfe’s piece describes a number of different strands to the general social and technological movement towards quantification and couples them with communication. Fine. No problems with that analysis. Automated diaries, blood sugar monitoring, chips in the soles of our shoes recording physical exercise, etc, etc, all feeding data into a set of databases that may or may not be accessible by other people to react to. A method of capturing all that time that is wasted without noticing it. A way to streamline activity. Be more productive. Really ?
Quote (of those subjecting themselves to self-tracking);
“they are also looking to understand their strengths and weaknesses, to uncover potential they didn’t know they had. Self-tracking, in this way, is not really a tool of optimization but of discovery, and if tracking regimes that we would once have thought bizarre are becoming normal, one of the most interesting effects may be to make us re-evaluate what “normal” means.”
Apart from the obvious internal contradiction, I wonder whether Wolfe questioned what it is about self-tracking that appeals to the American psyche (as his pieces seems to imply). What it is about systematically removing the spontaneous actions from everyday life that is seen as a positive ? To me its disturbing that a dominant global culture seems so eager to stop thinking and to export the idea that contemplation is no longer a valid goal in itself. Does that imply that Americans believe that understanding of self can only come with unceasing, unidirectional activity. Not only that, but a piece of mathematics is in a better position to tell you what you need than your own mind. Do you trust yourself so little ?
Of course there are good things about the life logging movement. Medical diagnostics is probably the best example, but the good things will tend to be the physical. Try as hard as you can to avoid trying to replicating mind functions. Please ? For me. Just this once.
This is where we cross into the issues around identity that JJ has been looking at. Online identity is something that I’ve dealt with professionally for the best part of a decade and I have to say, technically its no longer an interesting issue. However it is an interesting social and philosophical issue as we spend more and more time immersed in worlds made of other peoples imaginings.
The crucial thing to remember is that we cannot control how other people see us in a world where we can sprout wings and fly off to Brazil in a second. Identity as a projection of self is no longer irreducible if your existence is mediated. So while there is value in being able to prove that you are who you say you are in a transactional sense, there is less and less value in communicating who you are in a personal sense. Question; what is a hate crime in 2nd life ?
Neuroscience cannot read your mind
April 3, 2010
I’ve written about Newtonian science and the simple cause and effect interpretation of the physical universe that it embodies, and how the mathematics of complexity and statistical interpretations of the physical universe, such as quantum mechanics, have superseded that mechanistic view. What I would like to suggest is that neuroscience is treading the same path in its interpretation of the mind as a mechanistic system demonstrable by a physical understanding of brain function. This is not a new idea as far as I know, but I need to ‘say it out loud’ to show myself that I know where the limits lie.
I’ve been thinking about whether I believe that the mind could be replaced by the internet, and I think ‘no, but there could be functions that could be farmed out such as memory‘. Here I’m going to explore that idea with specific reference to the blossoming fields of neuroscience, neuromarketing, neuroethics and neuro-anything-else-they-can-think-of.
The mathematics of complexity and uncertainty, chaos theory, complex systems, or however else we wish to express the concept, all share the same fundamental tenet; that simple mathematical relationships can give in unpredictable results. This is shown by the Lorentz’s Butterfly Effect, but it it is also embodied in Godel’s incompleteness theorem and the Schrodinger’s Cat thought experiment. To me these are all similar aspects of the same idea; that we can never measure all variables sufficiently well to be able to have a 100% reliable model.
If we transpose this notion to the pursuit of neuroscience, where claims are being made almost to the point of being able to read the minds of experimental subjects, we should at least consider the nature of the systems involved before we accept the validity or even applicability these kind of claims.
Brain structure is primarily a function of the expression of DNA of the individual and DNA as a replicator a very mechanistic and ultimately predictable system. I say this because genes are quite simple. Their complexity is in their size, not their building blocks. That the Human Genome Project was able to sequence our genes using automated techniques suggests that a mechanistic approach to reading that material is appropriate. However once the brain has started to develop neuronal connectivity in response to stimuli (memories start to be formed in response to experience), that mechanistic interpretation is no longer applicable without having a set of meta-data that shows the context under which those connections are made.
What neuroscientists are doing using fMRI is establishing a work-book of that contextual meta-data under experimental conditions, and its very impressive that they are managing to exclude enough of the outside world to be able to see human responses such as lying and trust and jealousy in the data that they collect. I’m sure that, on average, they are seeing some functions of mind being expressed physically. BUT, what cannot, and indeed must not, be inferred from this work is that the responses from one individual’s brain can be directly equated to the responses of another individual’s brain.
We could go though a significant proportion of the human race, taking subjects from all walks of life and every corner of the globe and find average response curves for each chunk of the brain, but we would never be able to replicate the contextual meta-data to a fine enough resolution to be able to counter Godel’s incompleteness theorem as it applies to basic information or the individual’s brain development in response to experiences from its own unique viewpoint. The mechanistic interpretation of mind, that equates brain activity to mind function, breaks down under existing mathematical interpretations of the physical universe. We would need a whole new mathematics to be able to do what is currently being claimed for neuroscience. To be fair to the neuroscientists, many of them shy away from the grand claims, but enough are not that we see fMRI being cited in legal cases. Far from free will being dead and neuroscience proving a deterministic worldview, it is showing just how poor our quantitative understanding of mind really is.
This is not a new experience. Psychoanalysis promised an understanding of mind and motivation at the beginning and middle of the 20th century and arguably was the basis for the construction of the consumerist global economy. I wonder how far neuroscience will be pushed outside the lab.
Proponents see recent fMRI science as analogous to genetic fingerprinting; as a quantitative diagnostic tool. I would argue that it is more analogous to a form of psychoanalysis where interpretation is automated. In many of the new institutes and companies working with fMRI we see the objections to the wider application of fMRI-centered neuroscience being characterised as philosophical and relating to ideas of free will and determinism. I don’t see that as a valid or even relevant conflation. My counter-claim is that what is being claimed for neuroscience is not mathematically possible and that in ignoring the role of mathematical complexity scientists, lawmakers, economists and others are acting unethically. What is being seen is the brain and not the mind. That the brains responses are linked to the mind shouldn’t be a surprise but the simple Newtonian idea of cause and effect is not applicable where 100 billion neurons each have around 7,000 synapses many of which have been influenced by memory formation or physical conditions since, or even before, birth. Simply put, just because a specific cubic centimeter of grey matter demands extra blood flow in response to the same stimuli, it doesn’t mean its for the same reason.
If it is possible to mathematically model the mind, then it should be considered as a complex system inhabiting another complex system (the brain) and informed by a set of contextual meta-data (memories and experiences) as well as environmental stimuli. Divining motivation from brain activity is a step too far mathematically, but an approximation could be possible with a sufficiently large database to populate response curves with experimental data. Whether those response curves could provide useful predictive data can’t be known at this point, but what we can say with a good degree of certainty is that you’d need a large n-value to compensate for the free variables in two complex systems and the contextual meta-data.
Scientific Method as Strasberg’s Method
March 3, 2010
We’ve been hearing a great deal about science in the media in the context of climate change and new energy sources lately, and the quality of some scientific work has been called into doubt, and there have been calls for an increased understanding of science to try and stop misrepresentation by the media, blah, blah, blah. This call for dialogue between the fields of arts and sciences is happening on more and more occasions as science gets more difficult and mass media becomes less patient. Anyone still remember CP Snow ? So why don’t we look at things a slightly different way ?
Science is media
That sounds a bit odd, but philosophically science is a mechanism by which we try to understand the physical reality that we inhabit and mass media (especially news journalism) is also a mechanism to help understand the world around us. Their methods are different but their core goals are the same – enhanced understanding of reality.
So lets look at some recent science through a media lens. In fact let’s get PoMo on its ass !
Marshall McLuhan in ‘The Medium is the Massage’ posits that you perform the message that you wish to communicate. It doesn’t matter if that is verbally, ethically, artistically, mathematically or physically, what you do and how you do it IS what you say. On the other side of the coin if your performance does not tie in with your message the audience undergoes cognitive dissonance and the message is garbled, contradictory and ineffective.
Strasberg’s Method Acting technique is a great example of this. The actor does everything in his power to become the character in order that his whole performance reflects the experience of that being, in so doing the words and the physical body perform as one and, hopefully, the role is played well. The actor doesn’t actually become the character, that would be impossible, but he will take on or construct every aspect of that character that he can discover.
So if we take the recent CRU email scandal (yes, scandal), we have a set of scientists who perform their science under the scientific method which involves openness, respect for others results and views, self-criticism, peer-review and data validation. Over the years they have told us ‘trust us, we’re the best, we do good science’, in effect we’re following the scientific method, and now we find out that their performance is not backed up by their method. We thought that we were seeing the real thing, or at least a good approximation of the real thing with the scientists suffering for their art, but we were sold a poor performance. A shallow frontage. Its like finding out that a character that Al Pacino plays never actually liked coffee but Pacino forced a re-write because he couldn’t go without his morning joe.
For the record and as a former scientist I find the actions of the CRU scientists abhorant, but human (I never lived up to my own view of what a scientist is, which is why no longer call myself one, though I still perform the role of scientific critic). For me the affair doesn’t detract from the credibility of climate science as a whole, but its disturbing that their performance was more Lee Majors than Lee Strasberg.
They need to get their method back.
The Virtual Revolution – An Overview
February 21, 2010
Its been an interesting experience seeing the net through another’s eyes, or in the case of this short series of programmes – an number of other peoples eyes.
If you’ve read the other posts in this series you’ll know my views on the specific topics raised, but I thought that I’d just put a little piece together on what I thought of the work as a whole.
It wasn’t bad. It was wrong in places, naive in others, superficial in yet more, but as an accessible work summarising 20 years of the biggest shared technological endeavour of my lifetime it was OK. Seven out of ten.
It was remarkably short of forward looking content, but then it was a historical piece rather than a forecasting piece. It was also short on deeper analysis of what the technological trends say about us as people and as a species, but then we are only really now starting to find ways of looking at that. And on that point I’ll promote the Web Behaviour Test in order to maximise the data that they can gather.
It characterised me as a Web Leopard;
Fast-moving – Web Leopards like you are adept at getting information from the internet very quickly. Your speed is a trait you share with real-world leopards, which are among the fastest land animals.
Solitary – Leopards live alone, fending for themselves in isolated home ranges. Similarly, the Web Leopard likes to go it alone when looking for information, rather than rely on social networks, or other sites where the users create the content.
Specialised – Web Leopards are best suited to performing one task at a time rather than multitasking. The real-world leopard is similarly specialised, being perfectly adapted to silently tracking its prey before pouncing.
So now you know; I’m a fast-moving, predatory loner with a narrow view, big teeth and an attractive pelt. So much for the internet 
The Virtual Revolution – Part Four
February 21, 2010
Part Four – Homo Interneticus sees the good Doctor approaching some of the more interesting questions regarding the internet, though she still doesn’t really do any digging into the whole shared cognition/nature of reality connundrum which is one of my current favorites.
So just to go through some of the points raised;
Has Facebook change the nature of friendship ? It turns out that no, its just re-branded it.
Your friends and social group are still the same number and mostly the same people that they would have been without the software.
Which begs the question; why is it so successful if it offers no new reach to your social circle ?
Prof Robin Dunbar casually dropped the bomb that apart from the 150-ish people that you can claim as your clan/social circle/address book everyone else on your friends list is probably just a voyeur. So has Facebook replaced the soap opera as the acceptable face of curtain twitching ? Find your own surrogate family to watch out of interest, only now its not the Duckworths or the Fowlers. In the UK we’ve seen soap opera viewing figures decline by 50% over the last 10 years or so, it’d be interesting to know how much is direct replacement activity.
Update – No, not soap operas, reality TV shows. Those surplus friends are our own personalised Big Brothers.
We had Sherry Turkle (great name !) talking about the consumption of the private person as a result of the action of ubiquitous sharing of thought and activity, and about feeling obliged to openness in the networked society.
I’m not sure what to think about that comment. I’m not sure if that is simply a misunderstanding of the type of openness that the net engenders or an attempt to big up the profession of the psychologist (of which she is one) as professional listeners, or am I confusing them with psychiatrists ?
For myself I’m only open to the degree that I want to be. I feel no compunction about not answering personal questions if asked on the web. I don’t volunteer my deepest and darkest secrets. I treat this form of mediated interaction as I would a conversation in a pub, and assume that the interested will continue to read and the rest will slope off to the bar and find a more apposite conversation.
Information overload and associative vs linear data storage/retrieval was the next big topic. One that is close to my heart. Here the programme missed a big opportunity in not addressing one of the fastest moving sectors of quantitative neuroscience and its philosophical implications for fields as diverse as democracy & law and the nature of the mind. I’m not going to delve into all that right here right now, that’s for a later date. Suffice it to say that the Obama web campaign is small fry if a mathematical model of mind can be shared.
I’m going to follow up with a bit of reading around Vannevar Bush and Prof David Nichols because I don’t know their work.
In her summary the doctor passed two comments that I’ll paraphrase as;
At its best the internet may be an equivalent to the serendipity of the city – meaning that the melting pot of ideas and beliefs that has produced most of modern world’s innovation in science, technology, art and commerce is there to be had in a free and open web. I agree utterly and completely, its just a shame that in its efforts for global reach it has become fragmented and balkanised, as subsumed by commercial and political interests as any piece of prime real estate.
And second; the the web has the power to liberate humanity. I’m not sure what from though, presumably the commercial and political interests, but it might be more interesting if it were to free us from the constraints of our own inhibitions and provide an opportunity to evolve our thoughts past division and towards unity. The global mind as it was suggested.
