On 11 March 2019, Harold Channer invited me to the studios of MNN (Manhattan Neighborhood Network) in New York City to record two one-hour editions of the TV program “Conversations with Harold Hudson Channer”. To expand my thinking on topics from the second interview, here are four addenda:

• The Thinking Society
• Other references from the interview
• A brief Critique of AI (Artifical Intelligence)
• My addenda to interviews with Harold Channer to date

Is human behavior “a magnificent, fascinating, nuanced interaction between nature and nurture”? To what extent is our behavior controlled by our biology and to what extent does our behavior control our biology? What is the nature of a biolgically-based human being? What is unique about the behavior of humans in the animal kingdom?

These questions are the broad concerns of the 25 videos totalling 36 hours and 40 minutes constituting the free on-line edition of Stanford University’s Bio 150 course “Human Behavioral Biology” recorded in the spring of 2010 with Robert Sapolsky. The course is an accessible yet scientifically detailed introduction to modern biology’s understanding of human behavior. It is a broad biology-centered approach where animal comparisons and a broad systems perspective engage a way of understanding our psychology without too much solipsism. Sapolsky’s gift for story-telling and his style of boldly confronting the moral implications of his poignant topics make the lectures engaging edutainment. Topics include sexuality, violence, language, mental illness, religiosity, and individuality which are explained using the main biological subjects of evolutionary theory, genetics, ethology, endocrinology, and neuroscience.

Although I finished studying “Human Behavioral Biology” in July 2016, its continued influence on my thinking and the diffuse locations of my notes has led me to want to document its highlights, my notes on the videos, and the events I organized to explore aspects of the course in small groups. Hence this summary.

Perhaps, Sapolsky’s most profound contribution to my thinking came in the first lecture in his course where he composes a list of the dangers of categorial thinking:

1. We can miss the big picture by focusing on boundaries.
2. We tend to underestimate differences when two cases happen to fall in the same category.
3. We tend to overestimate differences when cases happen to fall on opposite sides of a boundary.

Of course, as Sapolsky himself acknowledges, categories are essential scaffolding for our thinking. In fact, I cannot imagine how we could think at all without some distinctions, some categories. But these profound dangers affect every distinction, every assumption, and every taxonomy that we might entertain. For me, this realization was stunning, profound, and transformative. Do you see the significance? Can you imagine the comport of its implications?

Another important aspect of the course was to better understand the profound interrelationship between genetics and environment. For me this really hit home when Sapolsky explained how the cure for one of the most devastating single-gene mutation diseases known, PKU (phenylketonuria), is treated with a simple modification to one’s diet; a genetic disease “cured” by a simple change to the environment! Nature and nurture are both categories that belie the far more subtle and interfused gene-environment interaction. That and the treatment of epigenetics, transcription factors, life history including perinatal development, and the limitations imposed by the requirement of controlled experiments in science gave me a much clearer understanding of how the gene-environment interaction belies many widespread but erroneous assumptions and studies in genetics.

Another significant feature of the course is the way it engages complex systems thinking by looking at the determinants of human behavior from most proximate to most distal: the behavior itself and its releasing stimuli (ethology), neurobiology, acute and chronic hormonal environment, perinatal biology & environment, culture, genetics of the individual, ecological and environmental context, and evolutionary history. Should we think of all causality as this kind of multi-layered, intricate confluences of many overlapping and interconnected systems? I think so! And Sapolsky gives a feeling for this way of thinking that is remarkably effective, if you put in the effort to think it through carefully.

Saplosky’s lectures boldly face many of the challenges posed by our modern understanding of biology as applied to human behavior. His engaging lecture style never shys away from controversy so he can address, with accessible but scientifically nuanced detail, broad questions about biological determinism and the biology of morality.

Below I present my curated edition of the course. It will, I hope, help you get even more out of the videos. It might even help you organize your own events to explore on ideas in the course with others. At the end I invite your feedback on this curation, and the materials it includes, and on the prospect that this kind of curatorial approach to organizing group explorations might prototype a new educational service to help our civilization better address its crisis of ignorance.

Harold Channer invited me to the studios of MNN (Manhattan Neighborhood Network) in New York City to record two one-hour editions of the TV program “Conversations with Harold Hudson Channer” on Tuesday the 25th of November, 2014. Since few things I write or speak come out fully baked, I thought I’d add a few additional thoughts to clarify, improve, or correct some of my comments. Since I value discussion, I sprinkled my remarks with many questions which I hope will elicit your feedback in the comments.

I participated in the ReVIEWING Black Mountain College 4: Looking Forward at Buckminster Fuller’s Legacy conference on September 28-30, 2012 in Asheville, NC, USA. I gave two talks (click on the links below to see the PDF presentations):

• Education Automation Now and in the Future. In this talk I recognize Buckminster Fuller as one of the conceptual founding fathers of the Open Educational Resources (OER) movement, detail six of his educational ideas, and give a brief review of several OER courses I’ve taken to indicate the kind of comprehensive education now possible using freely available on-line courses.
• Synergetics and Model Thinking. In this talk I synthesize Scott E. Page’s Model Thinking with Buckminster Fuller’s Synergetics. I introduce both subjects, then discuss the importance of model thinking. Then I sketch some ideas about how Model Thinking and Synergetics can inform a more incisive approach to science.

Please share any thoughts you might have about these presentations in the comments. I would value your feedback.

Since databases are a fundamental component of modern information systems, understanding at least their basics is essential knowledge for almost all citizens. Please read my review of Stanford’s excellent free on-line course Introduction to Databases which is posted on the blog Managing FOSS for Business Results at http://blog.remoteresponder.net/2012/01/19/learn-open-source-database-tools-from-stanford-for-free.

Please let me know what you think of it.

Each of us is connected through our parents and their parents and so forth to a first life form which has no parent and is composed and derived from non-biological forms. So each of us is intimately connected through our genealogical history to the non-biological Universe! Indeed, each of us is connected in this way to the whole Universe!!! It is this type of conceptual, big picture thinking that pervades Stephen Stearns’ free video course EEB 122: Principles of Evolution, Ecology, and Behavior at Open Yale Courses (OYC). Even though I do not think the separation between life and non-life is as clearcut as Stearns suggests, Jeannie and I thoroughly enjoyed our excursion into Biology with Stephen Stearns as our guide at OYC!

The Importance of Biology, Evolution, Ecology, and Behavior

Understanding biology is essential as civilization is inseparable from the great ecosystems upon which it is built and in which it is housed. Our future is inextricably linked to the always changing nature of the Earth-Biosphere system which provides our food and shelter. In EEB 122, we learned that the entire Earth has been sculpted by the biological technology we call “life“. At a more day-to-day human scale, medicine and health care are vital subjects in biology and in our economy (caring for the health of the ecosystem of cells, organs and their microscopic cohabitators known as “human” engages 9% of the economies in most OECD countries and nearly twice that in the USA). EEB 122 has a whole lecture devoted to medicine and more comments throughout the course.

Evolution theory has had a profound influence on modern thinking. From its nascent formulation by Charles Darwin, the theory of evolution has itself changed (evolved!) substantially over its first 150 years. I found it particularly interesting to learn that the modern theory is quite different from what my culture-imbued intuitions misled me to think. This course is eye-opening! Even if you disagree with some of the ideas of evolution (and who doesn’t have some questions and concerns about this subtle subject which is itself changing), this course corrects some of our endemic misperceptions. For example, Stearns asserts in lecture 3 that the notion of “survival of the fittest” is wrong! I had no idea that that iconic “sound bite” is but a dead-end on the road to the modern theory of evolution!

It’s not ignorance does so much damage; it’s knowing so darned much that ain’t so. — Josh Billings

With current concerns about global warming and other stresses on our environment, ecology is a vitally important subject. The point is reinforced by the work of three of the recent winners of the Buckminster Fuller Challenge which deeply engages the subject of ecology. The 2011 winner, Blue Ventures, conserves threatened marine environments. The 2010 winner, Project Hope, restores savannas and grasslands lost to desertification with a comprehensive program featuring cattle management. The 2008 winner, John Todd’s Comprehensive Design for a Carbon Neutral World, restores the ecological devastation of the impact of mining in Appalachia. The principles of biology and ecology are essential to better understand and contribute to these and similar initiatives to improve our management of Earth’s ecosystems while raising the standard of living of every human being. EEB 122 explains some of the vital principles that will underpin any such solution.

In summary, OYC’s EEB 122 is an excellent introduction to the basic principles of biology needed to better understand medicine, health care, evolution theory, ecology, the behavior of organisms, and biological technologies such as the enterprising work of the Buckminster Fuller Challenge winners. Finally, and perhaps most importantly, EEB 122 gives a conceptually broad, biologically detailed introduction to one of the most enchanting visions of change ever developed: the theory of the evolution of species.

How We Used the EEB 122 Course Materials

Jeannie and I started watching EEB 122 around New Year’s. We watch courses like this for edutainment. That is, we do not plan to become professional biologists, instead we watch video courses as a form cultural enrichment: How do biologists think? What do they know? What is the current understanding of evolution? I am deeply curious about how the world works. Video courses like EEB 122 are deeply enriching in this regard.

The view that randomness impacts and shapes our lives in profound ways has been gaining traction since 2002 when Daniel Kahneman won the Nobel prize in Economics for his work with Amos Tversky in characterizing human weaknesses when facing uncertainty. My thinking on the subject was first awakened by reading Nassim Nicholas Taleb’s book Fooled by Randomness which will give anyone who imagines they can think “rationally” a healthy dose of humble pie. A more helpful discussion can be found in Jonah Lehrer’s How We Decide which pays heed to our brain’s strengths while acknowledging our weaknesses. As I relayed in a post on the brain, mind and thinking, Lehrer recommends thinking about your thinking process to strengthen its decision-making function. Recently I finished reading Leonard Mlodinow’s The Drunkard’s Walk: How Randomness Rules our Lives which provides an accessible, historically detailed, and elementary introduction to the sciences of randomness and uncertainty and shows how they rule our lives.

These books have started to change my thinking about the nature of reality itself: I see now that randomness and uncertainty have an essential role to play. Interestingly, I shunned probability and statistics, the sciences of randomness and uncertainty, in college because I was steeped in Euclid, logic, and Buckminster Fuller’s “generalized principles” in Synergetics. I wanted to design destiny with deliberate application of knowledge … to worship at the altar of scientific determinism. Fortunately, Bucky taught me to “dare to be naïve” so I have been open to the new evidence about randomness. Now I suspect that Bucky and I were a little off about this subtle subject. It isn’t surprising, probability and statistics are among the newer branches of mathematics having developed mostly after the calculus was well established. They have not had enough time to pervade our collective consciousness.

Do you think the world is fundamentally deterministic or random? What influences have shaped your thinking and biases about the subjects of randomness, uncertainty, probability, and statistics? Do you think the increasing focus on the role of randomness and uncertainty in our lives is an important trend?

Randomness Rules Our Lives

Is Mlodinow’s thesis that randomness rules our lives really so convincing? Evidently so. Mlodinow finds dramatic evidence of randomness in our economic lives. He retells the poignant story of Sherry Lansing who led Paramount Pictures to huge successes in seven consecutive phenomenal years. Then after three years of bad results, she left the company. Did Paramount let her go too quickly? Evidently so because the pipline she left behind was full of new hits that restored Paramount’s revenue and market share. Shouldn’t seven years of success earn the right to forgive a few bad years? What if another great leader happened to have their three consecutive bad years at the beginning of their tenure? Do we replace them before their ship comes in? Mlodinow cites many other examples including the fact that “And to Think That I Saw It on Mulberry Street” was rejected by publishers some 27 times before Dr. Seuss’ career launched. Mlodinow also shows that student grades are often random and independent of their skill and knowledge.

Should we insist that our students, our schools, and our business leaders perform, perform, and perform with no “bad” years allowed? Do you believe that performance results are somewhat random? We invest a lot in exam and executive performance. Given the evidence, is that wise?

One part of Kahneman’s Nobel-prize winning work addressed the conjunction fallacy. Let A, B, and C be statements represented by a colored circle in the venn diagram to the right. The only case in which they can be simultaneously true is in the small area where all three colors overlap. So it is much less likely (less area) for three statements to be simultaneously true than for any one of them to be true. However, when someone weaves a story filled with a lot of concrete details, it seems more vivid and hence more believable than the statements considered separately: that’s the conjunction fallacy. Evidence of people falling for this fallacy has been documented widely even in medicine and the court room. We humans are easily duped by a good story!

It is surprising that the Nobel prize for the work showing how “blind” humans are to the elementary logic of the conjunction fallacy was only awarded one decade ago! Humanity has only just yesterday identified this basic weakness in our cognitive function! Add to the conjunction fallacy the many other fallacies and biases that Taleb, Lehrer, and Mlodinow show us to be subject to and one can see that Emanuel Lasker who was world chess champion for 27 years got it right: “In life we are all duffers”!

What is the significance of our weakness in understanding uncertainty? Do these weaknesses of the human mind subject us to the ravages of randomness? Are they a consequence of an inherent randomness in reality? Or do they simply lead to the appearance of randomness?

Our weakness extends to our sensory organs and perception as well. Mlodinow notes

Human perception … is not a direct consequence of reality but rather an act of imagination. Perception requires imagination because the data people encounter in their lives are never complete and always equivocal.

Mlodinow illustrates the problem by explaining that the human visual system sends “the brain a shaky, badly pixelated picture with a hole in it” (due to the relative weakness of our vision outside the fovea and the blind spot). In addition to conjunction bias, the sharp shooter effect, the hot-hand fallacy, availability bias, confirmation bias, and more, it becomes evident that “When we look closely, we find that many of the assumptions of modern society are based … on shared illusions.” And his conclusion

It is important in our own lives to take the long view and understand that streaks and other patterns that don’t appear random can indeed happen by pure chance. It is also important, when assessing others, to recognize that among a large group of people it would be very odd if one of them didn’t experience a long streak of successes or failures.

What shared illusions do we hold? How often are our lives subject to pure chance events? How important is serendipity? Do you believe that a long series of failures or successes is just the result of luck? When is it luck and when is it skill? How can we tell the difference?

The problem of randomness is deeper still: even machine-enhanced human sensing and measurement are fundamentally random! In Walter Lewin’s excellent video introducing physics and measurement in MIT OCW’s Physics I course, he says “Any measurement that you make without any knowledge of the uncertainty is meaningless.” Understanding uncertainty is at the heart of scientific measurement. No physics experiment ever found an exact match between theory and the laws of nature: data points always appear at random! Then add in effects like Heisenberg’s uncertainty principle and we see that randomness and uncertainty are vital elements of experience: they are pervasive.

In view of the elementary role of uncertainty in our perceptual and physical experience, what can we say about reality? What is reality if experience is so imprecise, fuzzy, uncertain, and fallible?

Glibert Strang’s 18.06 Linear Algebra course at MIT OpenCourseWare is exquisite! Jeannie and I went through it about a year ago. Strang’s approach to the material and engaging teaching style make the course a joy. Unlike other OER (Open Educational Resources) courses that we have taken, I cannot recommend just watching the videos. Instead one needs to really think about the concepts which is greatly facilitated by doing the exercises: this is typical for mathematics. It took significant effort to master the content. The material builds quickly and it was essential for us to work hard on each lecture. On several occasions we re-watched the videos and had to read the text carefully and collate with other on-line resources (some provided or referenced in the wonderful OpenCourseWare materials but some found by web searching, Wikipedia, etc.). We also used resources from our library (personal and public).

Jeannie and I were able to enjoy the whole course but it definitely took significant effort. This is the only video course that we have thoroughly studied and it was worth it!

Are there any other OER video courses on linear algebra? I have not found any which is a shame for such important material.

Linear algebra is one of the most useful branches of mathematics beyond introductory (high school) algebra and geometry. It is the algebraic study of intersections of complexes of lines, planes and hyperplanes and therefore has a strong geometrical component. Since each coordinate in the Cartesian representation of a line can be thought of as a variable, linear algebra provides a first order or “linear” approximation to multivariable systems. It is therefore a widespread and fundamental tool. Linear algebra has found applications in business, economics, engineering, genetics, computer graphics, social sciences, graph theory and much more. It is essential for anyone wanting to understand advanced mathematics. The matrix or an array of numbers is the basic object of study in linear algebra. So it is sometimes called matrix theory. Vector spaces are the abstract form of linear algebra.

Is that a good characterization of linear algebra? How would you improve it?

As citizens aboard SpaceShip Earth, we need to understand the principles of science and technology that shape our world. We need this knowledge to become effective co-designers of the world that Humanity is collectively building for today and tomorrow. We need to conceptually apprehend and comprehend how the Universe actually operates so we can better contribute to steering the forces that continually reshape our worlds. What are the most important concepts needed to proficiently build, use, steward, and re-generate the infrastructure of civilization on an on-going basis? Where can we get the information needed in terms that is easy to understand, easy to relate to, easy to use, and relevant to the problems we all face today and into the future?

Although Berkeley‘s free video course Physics C10/LS C70V: Physics for future Presidents AKA Descriptive Introduction to Physics is not the answer to all of these questions, it will explain the basic physics that is necessary to critically evaluate much of the information that inundates us each day. This course will significantly increase your ability to think more confidently about the heady questions above. It is a first step.

Is there an on-line video course that does a better job than Physics C10/LS C70V of explaining the broadly relevant principles needed to understand the big issues of the day?

In 2000, when Richard Muller started teaching a new course, Physics C10/LS C70V: Physics for future Presidents AKA Descriptive Introduction to Physics, at Berkelely he asked himself what are the principles and facts from physics that a student should understand to be able to make effective decisions on the Big issues of the day should they become President of the United States? From this ambitious question, a course was designed that is eminently useful. Even though it is oriented to the non-scientist, Physics majors at Berkeley can take the course for credit toward their degree, meaning it is even useful for scientists!

In an introductory post on the OER (Open Educational Resources) Movement, I explained that the Internet now offers illions of educational resources many with free video lectures. I’ve spent several years searching for and enjoying on-line video courses and Physics C10 is the most broadly relevant course with the most critical information for understanding how the world works that I have found. Everyone should watch, enjoy and think about this most enriching class of some 35 hours of free on-line video lectures!

What resources do you use to get comprehensively educated about the principles of science and technology and how they are changing our civilization so rapidly? What is the most important or broadly useful OER course that you have found on the Internet?

For the past couple of years, Jeannie and I have been engaged as students using so-called “open educational resources” (OER). We’ve “taken” a number of courses at MIT’s OpenCourseWare (OCW), OpenYaleCourses as well as dabbling in material from numerous other schools around the Internet.

I first read Buckminster Fuller’s short book Education Automation many years ago. I was amazed at Fuller’s foresight in advocating so much of what has now become the OER movement. Then a week ago I led a Ben Franklin Thinking Society discussion on Buckminster Fuller and the Open Educational Resources Movement. Here are my reflections on what I learned from preparing and participating in that discussion.

The Open Educational Resources (OER) Movement

The OER movement is simply an Internet-powered expansion of the time-honored practice of students and teachers sharing materials and ideas. On the Internet this sharing can include video and guided tutorials as well as traditional media such as lecture notes, homework assignments, textbooks, and exams. All of these materials were more difficult and more expensive to share before high-bandwidth Internet and modern computer systems became widespread. A group of educators has tried to define the OER movement in the 2007 CapeTown Open Education Declaration. Here is a short excerpt which gives the gist:

Unlocking the promise of open educational resources

We are on the cusp of a global revolution in teaching and learning. Educators worldwide are developing a vast pool of educational resources on the Internet, open and free for all to use. These educators are creating a world where each and every person on earth can access and contribute to the sum of all human knowledge. They are also planting the seeds of a new pedagogy where educators and learners create, shape and evolve knowledge together, deepening their skills and understanding as they go.

During the discussion, I asked participants if they had used any OER materials. Many of them had not. But I was excited to learn that one of the participants studied Linear Algebra with video lectures by Gilbert Strang. Jeannie and I put more time into that excellent course (even doing all of the homework, quizzes, and two and a half final exams) than any other OER course we’ve worked through.

As a self-learner, one of the most important elements of OER courses to me is that I can choose how to use the materials (unlike in school where one is more or less told what to do). For example, there are some courses where I just want an overview or a feeling for the subject, but I may not need to master the material. Like when we studied Introductory Biology at MIT’s OCW, we watched the videos and only briefly looked at the lecture notes. We skipped the homework and the tests. We quickly ignored the parts that were not, at that moment, of interest. I think this is a big improvement over school where I frequently suffered from wanting to go into more depth than the course in some parts and less depth in others. Using OER I can get the education I want, when I want it!

It should be noted that the OER movement has been partly inspired (according to this good review article on open educational resources in Communications of the ACM) by the FOSS (Free and Open Source Software) movement. I find this fascinating since I have long been involved in the FOSS / Linux world (I’ve written about that extensively in the managing FOSS blog). Fuller’s global vision has foreseen elements of both movements.

To find out more about OER, the wikipedia entry http://en.wikipedia.org/wiki/Open_educational_resources can get you started.

Buckminster Fuller on Education: Prescient Harbinger of the OER Movement

To prepare for the Ben Franklin Thinking Society discussion, I re-read Education Automation twice. That led to these five quotes on Bucky’s thinking on education including how he foresaw elements of the OER Movement. The quotes and my commentary expand the discussion to address some broader issues in education as well. The quotes are all from Education Automation which was published way back in 1962.
