Scientific findings (more or less)

“I was frankly demoralized that I’d be one of those people who ‘used to run’ and athletics would slowly become part of my past,” Jason said. It took time and effort to learn a new sport, he added. But now he loves swimming, especially, he says, the meditative aspect. “For 45 minutes, I can see little, hear only my thoughts, and talk to no one.” 
  • I have to contact a good friend who needs me.
  • Low carb diets are good for your heart.  Squaring that with wanting to leave a smaller earth foot-print to me is akin to "eating less."  As readers of this blog probably know, I am not a vegetarian, and I have moral and ethical issues with the idea that humans, who clearly have been evolving from and as meat eaters, should abandon all animal-based protein.  But in keeping with preserving life as much as possible, and in understanding that there's over 6 billion of us to feed, we have to do better about how we gather, prepare, and consume food.
  • Thankfully, nipple piercings have given some researchers a topic to study, and the study indicates that some serious things might happen.
  • Ray Kurzweil is a quack.  Oh, and for a variety of reasons I doubt his "singularity" will arrive. But PZ Myers isn't completely right either.

Meditation helps increase attention span!

Now what was I doing?

July 14, 2010
It's nearly impossible to pay attention to one thing for a long time. A new study looks at whether Buddhist meditation can improve a person's ability to be attentive and finds that meditation training helps people do better at focusing for a long time on a task that requires them to distinguish small differences between things they see.

The research was inspired by work on , who spend years training in meditation. "You wonder if the mental skills, the calmness, the peace that they express, if those things are a result of their very intensive training or if they were just very special people to begin with," says Katherine MacLean, who worked on the study as a graduate student at the University of California - Davis. Her co-advisor, Clifford Saron, did some research with monks decades ago and wanted to study meditation by putting volunteers through intensive training and seeing how it changes their mental abilities.
About 140 people applied to participate; they heard about it via word of mouth and advertisements in Buddhist-themed magazines. Sixty were selected for the study. A group of thirty people went on a meditation retreat while the second group waited their turn; that meant the second group served as a control for the first group. All of the participants had been on at least three five-to-ten day meditation retreats before, so they weren't new to the practice. They studied meditation for three months at a retreat in Colorado with B. Alan Wallace, one of the study's co-authors and a meditation teacher and Buddhist scholar...

The task lasted 30 minutes and was very demanding. "Because this task is so boring and yet is also very neutral, it's kind of a perfect index of ," says MacLean. "People may think meditation is something that makes you feel good and going on a meditation retreat is like going on vacation, and you get to be at peace with yourself. That's what people think until they try it. Then you realize how challenging it is to just sit and observe something without being distracted."



But then you knew that, didn't you?

(Sigh) That’s not what is in the body of knowledge of quantum physics…

James Ure talks a bit about quantum physics and Buddhism.  I'd opined on this issue before.  To summarize: I do wish people had a better understanding of what science is. But here's a nice starting point:

Science only talks about what science talks about.

It doesn't go further. So when James Ure writes...

Work within quantum physics has shown what Buddhists have known for centuries upon centuries--That an observing mind is necessary before countless variables within the field of potentialities become tangible to the deluded mind, which does so by compartmentalizing them into a "form." which it promptly labels and categorizes. In other words, an orange is only an orange when our mind labels it as such but in reality it is nothing more than a collection of interactions between various particles and perceptions converging together in that moment of observation as an, "orange." When dissected through meditation it is found that the orange is made up of the sun, the minerals in the Earth, clouds that provide the water to grow, vitamins, chemicals interacting with the spectrum of light to give off what the limited human eye and mind perceive to be orange. And many innumerable things, which themselves can be broken down even further.


 I cringe slightly.  Here's why...

That an observing mind is necessary before countless variables within the field of potentialities become tangible to the deluded mind, which does so by compartmentalizing them into a "form" which it promptly labels and categorizes.

 This seems  to say - I'm not sure, but it seems to say that a detection or estimation device is necessary to detect or estimate, provided that this device is labeled as "mind," and the output of the detection/estimation device does so by putting the observables into equivalence classes (i.e., the space of observables is partitioned into disjoint subsets via some common property uniquely assigning each point in the space to a particular subset of the space in the equivalence class).

Now that language is slightly better suited for detectors (that which does hypothesis tests on a finite or countable space of alternatives) versus estimators (which do so on uncountably infinite spaces of alternatives).

But to be honest, in the language of detection and estimation theory, this is kinda sorta of a tautology.  Let's continue...


In other words, an orange is only an orange when our mind labels it as such but in reality it is nothing more than a collection of interactions between various particles and perceptions converging together in that moment of observation as an, "orange."
Our mind labels an orange an orange because our mind is in part a sub-optimally evolved meat-based classifier, and by convention, some people label some fruits oranges. But the "reality" of an orange is no more or less the fruit itself or no more or less the collection of particles in time and their relationships in time, space, and energy.

The orange is that collection of particles, and vice versa,  and in part because of this collection of particles and their relationships it is perceived as an orange.  The other parts of this situation have to do with the observer of the orange and the medium in which the orange is observed.

This has nothing at all to do with quantum physics, I'm afraid to say..

 When dissected through meditation it is found that...

 Better to say, "when dissected through observation and experiment  it is found that..." if you want to be spot on as to what any science teaches.  Observation and experiment are only meditation insofar as they are performed with a practice of mindfulness of that task as meditation; without some direction towards that end, it is just another task performed with a monkey-mind.  Yeah, at some level they are the same and different, etc., but to transcend monkey-mindedness, skill must be employed, and that's what separates mindful observation and experimentation that a Buddhist scientist or engineer might perform and the garden variety of observation and experimentation.  But perhaps I digress.

Buddhism can teach you many, many, many valuable things - things that will save your life for a more opportune time to die.

But to adhere to the idea that by studying and practicing Buddhism you'll "understand" quantum physics or detection and estimation theory is indicative to that Buddhism must be studied and practiced more.

Science and engineering do not do metaphysics. The question of whether or not a detector is "good," beyond whether it is optimal in the Neyman Pearson sense or some other criteria is only true insofar as the modeled space of observables is worth observing, and science and engineering are silent on these issues.  Yes, the emptiness of existence is completely consistent with science because science can't tell you the meta-criteria for which you should do things; that is in the province of philosophy from which science has not split off; i.e., metaphysics, ethics, morals, and so forth.  Buddhism as practice and philosophy actually straddles all of those realms and more, and completely permeates each of those realms.

But please dear readers, that is not even metaphorically like quantum physics, OK?  Pretty please?

Is violence part of natural selection?

I can see that a whole lot of folks might have issues with this, from creationists to "the earth is a being" people and "biocentrists." From the NY Times:


...Most days the male chimps [in Ngogo Ngogo, in Uganda’s Kibale National Park]  behave a lot like frat boys, making a lot of noise or beating each other up. But once every 10 to 14 days, they do something more adult and cooperative: they wage war....

When the enemy is encountered, the patrol’s reaction depends on its assessment of the opposing force. If they seem to be outnumbered, members of the patrol will break file and bolt back to home territory. But if a single chimp has wandered into their path, they will attack. Enemy males will be held down, then bitten and battered to death. Females are usually let go, but their babies will be eaten. 

These killings have a purpose, but one that did not emerge until after Ngogo chimps’ patrols had been tracked and cataloged for 10 years. The Ngogo group has about 150 chimps and is particularly large, about three times the usual size. And its size makes it unusually aggressive. Its males directed most of their patrols against a chimp group that lived in a region to the northeast of their territory...

 The objective of the 10-year campaign was clearly to capture territory, the researchers concluded. The Ngogo males could control more fruit trees, their females would have more to eat and so would reproduce faster, and the group would grow larger, stronger and more likely to survive. The chimps’ waging of war is thus “adaptive,” Dr. Mitani and his colleagues concluded, meaning that natural selection has wired the behavior into the chimps’ neural circuitry because it promotes their survival.


 This quite likely is true; natural selection is dumb,  and only maximizes simple objectives, i.e., propagation of genetic sequences.  In this way it is also amoral.  I  know there are all kinds of folks who want all kinds of woo superimposed on the algorithmic structure in which we came to be. I would include in this certain evolutionary biologists  who would want to deny the the stochastic - yes, random - reset buttons that occasionally it species, e.g. meteors crashing into  the earth and what -not, because it messes up their narrative with creationists.  (I never seem to get a response from them when I bring up this issue on their blogs...oh well.)

We do need to go against our evolutionary machinery  in order to survive, evidently.  That is our lot.

Since when did we become close relatives of mushrooms????

But we are.  We are...



(Click image for larger view.)

I had been taught, I distinctly remember, that amoebas and other protozoa were animals because they could move. But evidently mushrooms are closer to us on the tree of life. And mushrooms were plants. But evidently the multicellular nature of mushrooms and their chitin cell-walls makes them closer relatives, as well as their rRNA.

It's kind of cool I'm getting to the age when "all the stuff they taught us in school is wrong!"

But let's get back to Buddhism for a minute.

Here's a "Tree of Life," with groupings partitioned as per closeness of rRNA; other metrics could likely be employed as well (I'm thinking of a variation of Hamming Distance on DNA, e.g.).

Have I lost anyone yet? ☺

OK, well forget about the Hamming Distance, except to think of it as  a distance between life forms.

Doesn't given this tree make it seem a bit arbitrary to say it's OK to eat these things but not these?

As I say a bit often on this blog, when it comes to vegetarianism, one should look at the larger context of health and maximize all of life in this regard.

One thing I will never criticize the Dalai Lama or others for is whether they eat meat or not.

More on Reincarnation and Buddhism

As I was reading the recent book on Hakuin to the left, it became clear to me, a quite rationalist, scientific minded person, that the notions or rebirth do indeed permeate much of the thought of Edo-era Japanese Buddhism.  Hakuin, is quite cosmopolitan in his use of devices which, if interpreted literally,  would be dismissed as woo and superstition today among the skeptics and rationalists.  And frankly, those bits would get in the way   of the larger purpose of Hakuin.  Similarly, jn my opinion, attachment to the tulku system and the merging of politics with religion has been disastrous for Tibetan Buddhism and the young boys who undergo déformation professionnelle to support that system.  What is the place, if any, for rebirth in Buddhism?  Yeah, we can interpret rebirth in such a way as to reconcile it with modern notions of multiverses, of awareness arising and descending and so forth.  But a literal rebirth?

As I said, Hakuin uses many opportunities for introducing the supernatiural into his writing.  Among the opportunities taken, there is kami speaking through a young boy, as well as the implicit understanding of a soul-less rebirth in which the reborn has no prior memory of "his previous life."  And of course there's the precipitating events of his life, about being worried about being reborn in a kind of Buddhist hell.   Although I have not read all of the existing English literature of Dogen,  what I have read does not leave me with a memory of what I would call the superstitious, so perhaps in this regard the Soto folks have it easier.

How to reconcile all of that with a modern outlook?  Well, is that even the right question?  In a certain sense, I think it it is: clearly if one engages in the practices developed and promulgated by Hakuin, one clearly develops an understanding and skill to be able to function in previously difficult circumstances.  There is no doubt about that, and I could set up an experiment to verify that, and indeed these practices do have their counterparts in mindfulness-based cognitive behavioral therapy.   So the reconciliation of the more superstitious elements of the traditions of Buddhism is a) something humans do naturally (resolve issues of cognitive dissonance) b) is useful for deepening the practice, and c) is a way of enhancing the view of the world that allows for this practice to be extended and useful for all beings.  So, yeah, how to reconcile?

Well, I would submit that it is necessary that, as I've previously written, that claims that are at variance with that which can be falsified via science should not be made as though science does not matter.   And those claims which cannot be falsified one should not demand that others respect them or honor them, simply as a matter of compassion and mercy as well as  savior-faire. Realistically, Tibetan monks finding the dead lama reborn as a young boy are treating the dead lama as the Virgin Mary and the young boy as a piece of toast in which they see her, or at least it is impossible to to show that they are not, and it is a bit arrogant to suggest that the rest of the world honor that decision simply because it is a "belief."   It may be honored for other reasons (such as wanting to not injure others' feelings, or wanting to ensure that things of higher priority are given the attention they deserve),  but there is no more reason to accept these sorts of things than it is to allow creationists to teach their kids creationism instead of science.

So my basic "reconciliation" is simply: that which is not useful to the objectives of Buddhism (helping beings, remember them?) should be treated sensibly and with compassion and mercy.  But we should be sincere about what is and what is not science and what is and what is not verifiable. 

In good science we have well-constructed experiments; these experiments allow for observation of results of  hypotheses to be well-separated.  That means that the possibility for  mis-identificatin of hypotheses causing the observation is minmal, or as we say there are a minimum of false detections and false alarms (or false positives and false negatives). In addition, these experiments are repeatable; they can be done time after time after time,  and the outcomes can be predicted. In communication systems, for example, a radio receiver is in effect a device which is constantly separating hypotheses of one type of signal received compared to others or no signal at all.  When real scientists speak of evidence, they mean  evidence in this way.  That's how you can tell a scientist from a non-scientist .  If they are talking about anecdotal evidence (e.g, "evidence" of reincarnation) , they are not talking about scientific evidence in the sense that scientists would use.  They may be talking about observations which might be able to be verified scientifically, but if such phenomena cannot be separated from naturally occurring explanations, we should insist that extraordinary claims do require extraordinary proof.  With regard to reincarnation, there just has not been that kind of evidence shown, and to insist on agnosticism in the face of such a damning lack of evidence is, in my opinion, unreasonable; it is as unreasonable as asserting that  we should be agnostic as to whether unicorns exist because there has been no good observation as to whether they do or do not exist.

So regarding my comments on Dr. Tart's work previously: if he does want to subject his work to scientific scrutiny, I will be happy to assist him in the protocols,  if I have the time, to help him collect $1 million from the James Randi foundation.

“The first self-replicating species we’ve had on the planet whose parent is a computer.”

So evidently we can, in principle, make living beings using computers instead of the old fashioned way.

The genome pioneer J. Craig Venter has taken another step in his quest to create synthetic life, by synthesizing an entire bacterial genome and using it to take over a cell. 

Dr. Venter calls the result a “synthetic cell” and is presenting the research as a landmark achievement that will open the way to creating useful microbes from scratch to make products like vaccines and biofuels. At a press conference Thursday, Dr. Venter described the converted cell as “the first self-replicating species we’ve had on the planet whose parent is a computer.”
“This is a philosophical advance as much as a technical advance,” he said, suggesting that the “synthetic cell” raised new questions about the nature of life
Other scientists agree that he has achieved a technical feat in synthesizing the largest piece of DNA so far — a million units in length — and in making it accurate enough to substitute for the cell’s own DNA.
But some regard this approach as unpromising because it will take years to design new organisms, and meanwhile progress toward making biofuels is already being achieved with conventional genetic engineering approaches in which existing organisms are modified a few genes at a time.
Dr. Venter’s aim is to achieve total control over a bacterium’s genome, first by synthesizing its DNA in a laboratory and then by designing a new genome stripped of many natural functions and equipped with new genes that govern production of useful chemicals. 

 Naturally this calls into question what divides life and non-life, which, for Buddhists of the Mahayana variety, isn't so bad because of our non-dualism.  But this is reason number N, that I'm glad I'm not a monotheist.

Meditation, Neuroscience, Observability and Controllability

I wrote a comment here on the C4chaos blog, about some talks that Shinzen Young gave on enlightenment, meditation and neuroscience.

I think it's a great thing that neuroscientists study meditation and that experience, and correlate it with what is observed.

However, as I note there, I'm deeply skeptical of claims such as:

However, the kind of thing that I have in mind would require and exceedingly precise kind of biofeedback where we knew exactly what kind we were dealing with, we knew the necessary and sufficient physiological correlates of enlightenment itself, and then we could use biofeedback to train those correlates more efficiently. Now, having said that much, please do not think that I am so naive as to think that that in it of itself is going to bring a person into enlightenment. However, I would strongly suspect that it could cut the time required to a tenth. There’ll be all sorts of other ancillary trainings and learnings and life experiences that would have to go around that. You’re not just gonna hook somebody up to a machine and just because their physiology emulates enlightenment think that they’re gonna get enlightened. But boy, it could sure make my job a lot easier, if we could do stuff like this. And that’s what I’m looking towards from practical point of view. Why?

...Only a small number of people participate in the meditation endeavor. Not elitist because meditators don’t want to spread it. Meditators do their best to spread it. But it’s too hard, it takes too much time, people aren’t interested, it doesn’t seem relevant. If we had a way of bringing deep experiences more easily, then we could reach a significant portion of the population, and we could start to make a change on this planet.

Besides what I wrote there (expectations regarding meditation, etc.) I would raise yellow flags of caution as both a Buddhist and a systems engineer with expertise in communication theory, information theory, signal processing and control theory.

First, let's put out front where the technology is: you can do all kinds of things with devices now to emulate feelings in the brain, and even perform simple control functions such as moving a mouse on a screen and what-not. But, there's notions of controllability and observability that, when applied to the fact that our brains are "to go" obviate the need for such devices.

Even if such a device, in meditation could speed up the experience of emptiness or sammadhi, the fact is all that's kind of irrelevant if you aren't applying this moment to moment in everyday life. You'd need to be able to observe the ensemble of mental states during the day (which, even in restricted areas of the brain is not trivial in the near future), and then you'd have to have some control mechanism to put it where it's "supposed" to be. And point is, it's "supposed" to be where it already is.

We sit on a cushion to get off the cushion, and actually expressing sunyata moment to moment in our interaction with our fellow beings and our environment is where the rubber really meets the road.

Because of what I said above, I'm not sure we can do this, and if we can...then...could not we be able to, just as well, convert a whole segment of society into paranoid, delusional, enraged teabaggers? How could you stop folks from doing that, as long as they thought there was something in it for them? Hell, people are already doing that with crude means because they think there's something in it for them. Which, I suppose makes a counter argument for creating neuropsychological techniques to "walk people back" from paranoia, delusion, and rage. But I suspect that's a different brain app than a Nirvana app.

To me, as a technologist, we always have to view technology as a double edged sword. Technology is never wholly on the side of bodhisattvas or the enraged and fearful (or angels and demons, if you prefer). It's neutral. So we need to be careful.

So, yeah, let's study how the brain functions in sammadhi, for sure. But as someone wrote about Masters and Johnson's sex research, ultimately that's not the point, except that in the case of sammadhi and kensho (見性), the feeling isn't the point either.

Practice Makes Perfect

I hate the genre of "science proves Buddhism" story...although, as an applied scientist and a Buddhist I do have a certain fondness for the "this story correlates with Buddhist practice" genre.

And that's what I thought in reading this NY Times Book Review article on "The Genius in All of Us" by David Shenk.

Motivational gurus from Dale Carnegie to Tony Robbins have long promised access to these hidden stores of genius. Now here comes David Shenk with “The Genius in All of Us,” which argues that we have before us not a “talent scarcity” but a “latent talent abundance.” Our problem “isn’t our inadequate genetic assets,” but “our inability, so far, to tap into what we already have.” The truth is “that few of us know our true limits, that the vast majority of us have not even come close to tapping what scientists call our ‘un­actualized potential.’ ” At first it would seem that Shenk, the author of thoughtful books on information overload, memory loss and chess, has veered into guru territory. But he has assembled a large body of research to back up his claims.

Two bodies, in fact. The first concerns the emerging science of epigenetics, the study of how the environment modifies the way genes are expressed. Since the days of Crick and Watson, we’ve tended to see genes as a set of straightforward instructions, a blueprint for constructing a person. Over the last 20 years, however, some scientists have begun to complicate that picture. “It turns out that the genetic instructions themselves are influenced by other inputs,” Shenk writes. “Genes are constantly activated and deactivated by environmental stimuli, nutrition, hormones, nerve impulses and other genes.” That means there can be no guaranteed genetic windfalls, or fixed genetic limits, bestowed at the moment of conception. Instead there is a continually unfolding interaction between our heredity and our world, a process that may be in some measure under our control.

The second body of research investigates the nature of exceptional ability and how it arises. We’ve traditionally regarded superior talent as a rare and mysterious gift bequeathed to a lucky few. In fact, Shenk writes, science is revealing it to be the product of highly concentrated effort. He describes the work of the psychologist Anders Ericsson, who wondered if he could train an ordinary person to perform extraordinary feats of memory. When Eric­sson began working with a young man identified as S.F., his subject could, like most of us, hold only seven numbers in his short-term memory. By the end of the study, S.F. could correctly recall an astonishing 80-plus digits. With the right kind of mental discipline, Ericsson and his co-­investigator concluded, “there is seemingly no limit to memory performance.” Shenk weaves accounts of such laboratory experiments, conducted on average people, with the tales of singularly accomplished individuals — Ted Williams and Michael Jordan, Mozart and Beethoven — who all worked relentlessly to hone their skills...

...Forget about genes as unchanging “blueprints” and talent as a “gift,” all tied up in a bow. “We cannot allow ourselves to think that way anymore,” he declares with some fervor. Instead, Shenk proposes, imagine the genome as a giant control board, with thousands of switches and knobs that turn genes off and on or tune them up and down. And think of talent not as a thing, but as a process; not as something we have, but as something we do.



Yep. No fixed essence to us it seems.

And, isn't this really all about Zen Budhist practice or what?

Shenk doesn’t neglect the take-home point we’re all waiting for, even titling a chapter “How to Be a Genius (or Merely Great).” The answer has less in common with the bromides of motivational speakers than with the old saw about how to get to Carnegie Hall: practice, practice, practice. Whatever you wish to do well, Shenk writes, you must do over and over again, in a manner involving, as Ericsson put it, “repeated attempts to reach beyond one’s current level,” which results in “frequent failures.” This is known as “deliberate practice,” and over time it can actually produce changes in the brain, making new heights of achievement possible. Behold our long rumored potential, unleashed at last! Shenk is vague about how, exactly, this happens, but to his credit he doesn’t make it sound easy. “You have to want it, want it so bad you will never give up, so bad that you are ready to sacrifice time, money, sleep, friendships, even your reputation,” he writes. “You will have to adopt a particular lifestyle of ambition, not just for a few weeks or months but for years and years and years. You have to want it so bad that you are not only ready to fail, but you actually want to experience failure: revel in it, learn from it.”

Now, if the reviewer had a notion of "karma," she'd know why some folks instill and cultivate discipline and some do not.

Moreover, of course we probably won't all be Mozart, Ted Williams, or Hakuin. But that's not the point. At least, it's not the point from a Buddhist perspective.

Some folks, from the 12 Step world, I think, have a notion of "Insanity is repeating the same mistake and expecting a different outcome." I think this aphorism should be changed a bit to: "Sanity is repeated practice in the direction of perfection." The thing is, such repeated practice in the direction of perfection will inevitably result in a mistake, the "one continuous mistake" of which Shunryu Suzuki spoke, I think. Moreover, denial of my aphorism in favor of the "insanity" aphorism is itself insanity, since it opposes reality.

MBCT better than antidepressants?

In the midst of some last-minute channel surfing yesterday, I came across some college lecture which was discussing this study.

In a study, published December 1, 2008 in the Journal of Consulting and Clinical Psychology, MBCT proved as effective as maintenance anti-depressants in preventing a relapse and more effective in enhancing peoples' quality of life. The study also showed MBCT to be as cost-effective as prescription drugs in helping people with a history of depression stay well in the longer-term.
The randomised control trial involved 123 people from urban and rural locations who had suffered repeat depressions and were referred to the trial by their GPs. The participants were split randomly into two groups. Half continued their on-going anti-depressant drug treatment and the rest participated in an MBCT course and were given the option of coming off anti-depressants.
Over the 15 months after the trial, 47% of the group following the MBCT course experienced a relapse compared with 60% of those continuing their normal treatment, including anti-depressant drugs. In addition, the group on the MBCT programme reported a higher quality of life, in terms of their overall enjoyment of daily living and physical well-being.

As should be well known, I'm not a fan of "science proves religion" posts, but this is certainly worth noting.
