While flawed, this is still an excellent summative article from The New York Times on the brain and learning ( hat tip to Michele):

Adult Learning | Neuroscience  How to Train the Aging Brain

….Recently, researchers have found even more positive news. The brain, as it traverses middle age, gets better at recognizing the central idea, the big picture. If kept in good shape, the brain can continue to build pathways that help its owner recognize patterns and, as a consequence, see significance and even solutions much faster than a young person can.

The trick is finding ways to keep brain connections in good condition and to grow more of them.

“The brain is plastic and continues to change, not in getting bigger but allowing for greater complexity and deeper understanding,” says Kathleen Taylor, a professor at St. Mary’s College of California, who has studied ways to teach adults effectively. “As adults we may not always learn quite as fast, but we are set up for this next developmental step.”

Educators say that, for adults, one way to nudge neurons in the right direction is to challenge the very assumptions they have worked so hard to accumulate while young. With a brain already full of well-connected pathways, adult learners should “jiggle their synapses a bit” by confronting thoughts that are contrary to their own, says Dr. Taylor, who is 66.

Teaching new facts should not be the focus of adult education, she says. Instead, continued brain development and a richer form of learning may require that you “bump up against people and ideas” that are different. In a history class, that might mean reading multiple viewpoints, and then prying open brain networks by reflecting on how what was learned has changed your view of the world.

“There’s a place for information,” Dr. Taylor says. “We need to know stuff. But we need to move beyond that and challenge our perception of the world. If you always hang around with those you agree with and read things that agree with what you already know, you’re not going to wrestle with your established brain connections.”

There are some problems with the article, starting with the assumption that the negative differences of middle aged brains are a product primarily of age rather than habitual use. While there are developmental differences in cognition, if you stop doing something at any age which you are mentally proficient – say calculus equations, creating rhymes, playing chess – you will grow less efficient at that activity over time. Use it or lose it. People in their 40’s to 60’s are typically leading lifestyles that are very different from full time students.

There is also enormous value in mastering a second field ( which initially is all “new information”). A person’s accumulated expertise, formal education and life experience can be thought of as a “cognitive map“. Ideally, you want to both continuously enlarge the size of your cognitive map (“lifelong learning”) and improve the efficiency and versatility of your ability to access the information (recall), discover patterns or elusive aspects (insight, horizontal thinking, analogies) and use the knowledge constructively and purposefully ( synthesis, creative thinking, problem solving).

 By nature though, humans are mentally lazy.  We are predisposed toward “Automaticity” and would find it hard to get through the day attemppting to reason through every action in a sequential series of steps, so our brains are inclined to take the path of least resistance . Recall is a lot easier a cognitive function than is generating new insights, orientation of new data into the big picture or engaging in complex problem solving, which is why the mental stimulus of novelty and conflicting viewpoints are so important. We need to be prodded.

It is no coincidence that tolerating exposure to differing viewpoints (political, methodological, religious – whatever) and assessing them objectively and critically is something that most adults have great difficulty doing. The defensive emotional surge that many people feel when facing antipodal views not only protects the ego, but by intefering with the ability of the frontal lobes to engage in critical, abstract, reasoning, the brain prevents the “waste” of time/energy of having to do the hard work of (perhaps) fundamentally re-thinking the premises that order our worldview. Not only are many zealous partisans unwilling to listen to opposing views and process their arguments rationally and fairly, they are often cognitively unable to do so! Unfortunately, that “bitter medicine” of evaluating critical feedback is exactly what our brains need in order to stay mentally sharp and adaptive.

The true believers who organize echo chambers and police the community for adherence to the “party line” are drugging their brains with ideology and corrupting their OODA Loop.

This will be the first of several related posts. 

The other day, I happened to be talking to my friend Dr. Von, a physicist and educator, and he brought up a post by The Eide Neurolearning Blog, on educating children in terms of “big picture thinking”:

What is ‘big picture’ thinking? Business consultant Andrew Sobel described it as:

1. Having a simple framework
2. Using analogies and metaphors
3. Developing multiple perspectives
4. Looking for patterns and commonalities….

Instead of training for compliance, careful rule-following, and exact memorization or a paragon of crystallized intelligence, we need to make more room for ‘big picture’ thinkers – while still recognizing the need for basic skills and knowledge.….Pint-sized big picture thinkers really do exist and they seem to be over-represented among gifted children who underperform or cause behavioral disruptions in their early elementary school years. Many of these kids are ‘high conceptual’ thinkers, those who like discovering novel subjects, themes, and things that don’t make sense(“The thing that doesn’t fit is the interesting thing” – Richard Feynman), but the reason for this is often not random – inductive learners (learners who derive rules from examples) use novelties to generate new hypotheses or new rules.If you really want to teach and interest big picture thinkers, you would expose them to rich multisensory and chronologically-advanced experiences. Look for subjects, phenomena and ideas that could be compared and contrasted. Complexity should be embraced and not shunned. For big picture thinkers – complex is simple and simple is complex. Complexity often brings more meaning because there are enough examples that one can make a pattern.….Many of them are seeking the overarching framework inside which they can put their new bit of knowledge. Often these are ‘why’ kids – who need to know why something is true, not just that something is true.

The Eides have given an excellent explanation of the big picture thinker as a cognitive type and had some implied suggestions in that description on how a teacher or professor could approach students to get them thinking – models, metaphors, analogies, exposure to patterns and multiple perspectives. Note: all students willl derive some benefit from these techniques and become better at seeing the larger context. Many people can, with sufficient practice, can become significantly better, but the natural big picture thinkers are the ones who will react with insightful leaps of reasoning, imagination and questions with little or no prompting.

Unfortunately, such experiences in public schools and even our universities have become increasingly rare. Dr. Von explains why:

When I talk with students (juniors and seniors in high school) about how different subjects and classes are taught, invariably it comes down to great amounts of memorization. Most students, when you engage them in real conversations about the education they receive, will open up freely and get right to the point…because of the continued emphasis on grades and GPAs by colleges, students feel the need to focus first on memorization and get the grade on the test, and then move on to the next topic without much concern with what was just studied. When this is the case in school, has true learning just occurred? Likely not, if students are unable to recall and actually apply concepts that were covered in the past.

….To make matters worse, as students rely so heavily on memorization and short-term success on tests (and this is driven home even more in the ‘high stakes testing’ environment we find ourselves in in the era of No Child Left Behind, as resently implemented), those students, many of whom are gifted, as the Eides point out, who prefer complexity in their learning, are not benefitting from the way many (most) classrooms are run. By complexity, I mean those students who want to ‘see the big picture.’ Those students who want to know why something works, and how it is related to the material that was studied last semester as well as to the material that was covered in another class. For example, I love when students in my physics classes come to me asking about how to interpret and apply a particular integral result which was just studied in calculus class, or how Einstein’s theories changed political and military history, as studied in a history course. Those moments happen every so often, as a result of student curiosity and their wanting to truly learn about the material rather than memorize something for the test, and good teachers recognize such moments when they happen…

It falls to me to discuss why it matters: As a nation we are crippling the next generation of visionaries by retarding their intellectual growth with bad educational policy as surely as we might if we were adding lead to their drinking water.

Scientists and inventors, philosophers and artists, entrepreneurs and statesmen, individuals who conceive of and accomplish great things do not emerge from schools and colleges that emphasize low-level thinking and a curriculum without intellectual depth or rigor. They emerge in spite of them.

To force a systemic improvement in public education, the Bush administration pushed through “No Child Left Behind” with rigid timetables, mandated high stakes testing and punitive consequences for schools and districts not making standards. That is to say, the Bush administration addressed the lack of rigor in educational process with a sledgehammer – but ignored the lack of rigor in educational substance ( at least directly – under NCLB some schools had to toughen their curriculum to teach to the state test, but other schools or schools in different states dumbed down for the same reason – curricular alignment).

That NCLB forced public schools to ensure that our weakest students verifiably succeed at understanding the fundamentals is laudable. That this emphasis increasingly comes at the cost of schools only educating all their students at the level of the fundamentals is inexcusable. Perhaps criminal. NCLB is the overarching legal framework that was superimposed on a system whose content was (and often still is) frequently less than demanding and taught by instructors who themselves have not majored in the subject they are teaching. 

At the postsecondary level, long before the measure and punish model of NCLB arrived at k-12 schools, colleges and universities abandoned any semblance of a core curriculum or traditional canon and undergraduate degree requirements were larded with plenty of au courant esoterica as course options. Esoterica formerly left for footnotes in dissertations or as the subject of longwinded, diatribes at the dreary meetings of extremist splinter parties. Ivy League, big state schools, small third tier colleges – it does not matter; with only a few exceptions, the “cafeteria a la carte” model of undergraduate education prevails.

While a few students absorb and become true believers of fashionable cant, most students graduate high school and college unaffected by the large amounts of rubbish and trivia they have been exposed to because it was presented without any kind of sensible context and being committed to short term memory, quickly forgotten. The real damage to students comes from the cumulative effect of the absence of substance – the waste of time where meaningful content and the pressure to think through hard problems should have been.

The costs of educational myopia are here and they will grow worse with time. We already see sharply declining public support for science (because more people are now ignorant of basic scientific literacy),  lower rates of innovation and other negative economic effects. In the area of governance, across the board, regardless of party label or ideology, we have national leaders in their 40’s, 50’s and early 60’s who see the world primarily in short-term, tactical terms and who confuse career or class interest with governing in the national interest. Oligarchy is inherently a non-strategic worldview because it eschews making choices because choices require sacrifice in the near term in order to acquire systemic advantages in the long term. 

“Oligarchy” seems like a a harsh word because we think of “oligarchs” as being selfish, exceedingly greedy, political sociopaths. While such figures do exist outside of TV and the movies (Burmese junta, Iranian hardliners, Soviet politburo etc.) most people are neither particularly malicious nor eager to consciously and openly do things society acknowledges to be wrong or counterproductive. Even less so are they eager to be seen by the public as incompetent. The problem is that, frequently, people are prisoners of their own limited frame of reference and, when their conscience might be tweaked, they excel at rationalization and denial.

This is not a question of smart or dumb or of expecting politicians to be moral paragons. There’s plenty of IQ wattage inside and outside of Washington, DC and petty larceny in politics goes back to the stone age. Rather, on average, the difficulty is that our nation’s intellectual potential has not been effectively maximized. Is it reasonable to educate people in a way where all subjects are disconnected from one another, prioritizing narrow specialization, emphasizing accumulating facts over understanding principles, rewarding the “right answer” instead of the “best question”, demanding conformity instead of curiosity and then expect our leaders to be visionaries and adaptively creative statesmen who think in strategic terms?

Why would our societal orientation in complex, dynamic, fast moving situations be good when our educational system trains people only to think through simplified, linear, sequential problems? Strategic thinkers need to be able to see “the big picture” and handle uncertainty, or they cannot be said to be strategic thinkers.

The ship of state has been steered, over the last forty or so years, into an epistemological cul-de-sac and we are headed for the rocks. America needs a grand strategy for a competent citizenry in order to reach the point where it can again have a grand strategy to deal with an unruly world.

Steve DeAngelis had an excellent and timely post on the cognitive diversity involved in the creative process of innovation, working off an article in The New York Times, Innovative Minds Don’t Think Alike:

“The Curse of Knowledge”

“There is a lot of denial when it comes to the curse of knowledge. Nobody likes to admit that they are incapable of thinking out of the box. Entrepreneurs pride themselves on being able to envision the “next big thing.” Designers and inventors are always looking for better ways to do things. The good ones have learned tricks that help them break down the walls of knowledge. According to Rae-Dupree psychologists have conducted experiments that demonstrate that a person’s first instinct is to think about old things rather than new things. That’s not really surprising since we can only think about what we know.

‘Elizabeth Newton, a psychologist, conducted an experiment on the curse of knowledge while working on her doctorate at Stanford in 1990. She gave one set of people, called ‘tappers,’ a list of commonly known songs from which to choose. Their task was to rap their knuckles on a tabletop to the rhythm of the chosen tune as they thought about it in their heads. A second set of people, called ‘listeners,’ were asked to name the songs. Before the experiment began, the tappers were asked how often they believed that the listeners would name the songs correctly. On average, tappers expected listeners to get it right about half the time. In the end, however, listeners guessed only 3 of 120 songs tapped out, or 2.5 percent. The tappers were astounded. The song was so clear in their minds; how could the listeners not ‘hear’ it in their taps?’

….Rae-Dupree notes that there are ways to “exorcise the curse.” I have written about one of those ways before. Frans Johansson calls it “The Medici Effect” in his book of the same name. He argues in favor of creating a space in which people from diverse fields of expertise can get together to exchange ideas. The Medici’s, of course, were a wealthy and powerful Italian family who played an important role in the Renaissance. The family’s wealth permitted it to support artists, philosophers, theologians, and scientists, whose combined intellect helped burst the historical pall known as the Dark Ages. Getting people with different knowledge bases together means that none of them can remain within the walls of their own knowledge domain for long. As a result, good ideas normally emerge”

Acquiring disciplinary expertise typically takes approximately a minimum of 7-10 years for the student to master enough depth of knowledge and requisite skill-sets to become an expert practitioner. In many fields, notably pure mathematics, theoretical physics and musical composition, this period of early mastery is often the most fruitful in terms of significant contributions of new discoveries or the kinds of innovations that Mihaly Csikszentmihalyi and Howard Gardner consider to be “Big C” creativity. Einstein’s papers on Relativity or Newton’s early exposition of the Laws of Motion being the great historical examples of paradigm-shifting innovators. If a practitioner remains entirely in that field for their career, cultivating an ever greater and rarefied depth of knowledge ( and thus having fewer true peers and more disciples) further contributions are likely to be of the “tweaking” and “critiquing” variety. Useful but not nearly as satisfying as the grand “breakthrough” moment.

I suspect that the reason for this decline in major creativity has to do with two realities of expertise:

First, the analytical-reductionist emphasis on vertical thinking; cognitively, for an acknowledged expert, there is a great deal more time spent on mere data retrieval, interpretation within accepted frames and scanning patterns for consistency than there is original problem solving, questioning premises, speculating, imaginative brainstorming, analyzing anomalies and thinking analogically. The latter are too often the tools of the novice, the student, the child, the layman trying to grasp in the process of learning what  they do not yet fully understand. Too often these powerful ( though tiring and time consuming) cognitive skills are set aside in favor of operating on “autopilot” once the student has achieved mastery. Unless consciously practiced, the hard thinking tends to stop when one is constantly confronted by the routine.

Secondly, disciplinary fields, like all forms of collective human endeavor generate their own cultures with accepted norms, rituals, in-group terminology, orthodoxies, implicit and explicit rule-sets, authoritative hierarchies, politics, and peer presssures. As one gains seniority it becomes harder and harder to rock the boat because challenging one’s peers brings professional risk, social ostracism and conflict while validating the community’s beliefs yields rewards, advancement and praise. A phenomenon of human nature that has been observed by thinkers as disparate as Thorstein Veblen, Thomas Kuhn and Howard Bloom. Vested interests are irrational in their own defense. It is here that knowledge can be come a “curse” and expertise a form of incompetency or blindness to the larger picture ( “educated incapacity” in Herman Kahn’s terminology).

The answer to this problem requires actively determining how we will think about our knowledge. Steve pointed to cultivating “the Medici Effect” of multidisciplinary interaction in his post, a highly effective practice for organizations who want a work force rich in “intellectual catalysts”. To this, I would add another important set of variables: freedom and time. Seemingly non-productive activities, when we are “fooling around” appear to permit an indirect processing of information that leads to a burst of insight about the problem we have failed to consciously solve ( the “idea came to me in the shower” effect). Time needs to be set aside to explore possibilities with acceptance that not all on them are going to pan out ( Frans Johnansson covers these points at length in The Medici Effect). Permitting employees autonomy strikes at the power and culture of American middle-level management, which is why inculcating such practices often founder, even when introduced support of organizational leaders ( “leadership” and “management” are entirely different outlooks) due to the passive or active resistance of those whose position or status in the organization depends upon exercising control.

On the individual level, novelty is an important stimulus toward horizontal thinking. New concepts and experiences stoke our curiousity and “wake” our brains out of the usual, habitual, patterns in which we operate. Attention levels increase as we begin to operate at the beginning of the learning curve and start to recognize parallels and connections between old and new knowledge. We can also make deliberate choices to think “outside the box’ by voluntarily changing our position, perspective and scale, reversing our premises, engaging in counterfactual thought experiments and other lateral thinking exercises. In this way, we are more likely to be behaving metacognitively, aware of both our own thinking and more alert to the nature of the information that we are receiving.

We have something of a paradoxical situation. An untrained mind, looking at a field with “new eyes” is the one most likely to notice that which has eluded the expert of great experience but is least able to make use of, or even assess critically, the importance of their insights. A trained, disciplinary, mind has the capacity to extrapolate/interpolate, practically apply new insights or think consiliently with great effect but is the mind least likely to have any insights that could conflict with the major tenets of their disciplinary worldview.

Having the best of both worlds means avoiding either-or choices in cognition in favor of both. Analytical-reductionism and Synthesis-consilience have to be regarded by serious thinkers as tools of equal value. Imagination and vision should be as important to the genetic microbiologist or physical chemist as it is to the artist but they should be regarded as a complement to the scientific method and logical, critical, analysis, not as a substitute. Looking for alternative choices to a course of action should be valued as highly as correctly identifying the likeliest outcome of the action. We can embrace intellectual curiousity and shun “paralysis by analysis”.

John Robb puts on his futurist hat and engages in some imaginative scenario thinking (PDF) over at Global Guerillas. Note John’s comment:

“The goal of this brief is to get people thinking about the future in a way that helps them make decisions today.”

John has the methodology right. Most experts, habituated to the over-use of analytical thinking, will try to nit-pick scenarios like these to death from the inception , either reflexively or intentionally in order to avoid having to reexamine cherished ideological assumptions, instead of engaging in the thought experiment. This is the major cultural-cognitive reason bueaucracies and academic institutions are notoriously poor at thinking outside the box or anticipating anything other than directly linear outcomes of policies. 

Analytical-reductionism was a reasonable enough epsitemological approach for the 19th and 20th centuries of the “Second Wave”, “Mass Man”  industrial-bureaucratic nation-states. It’s not enough for the more heterogeneous, alinear, high-velocity, “complex networks as evolving ecologies” of the 21st century. We need other cognitive tools in our kit alongside analysis.

A READING UPDATE

Despite some reservations about Howard Gardner’s normative weighing of various “multiple intelligences” and uneven conceptual development in his earlier works, I’ll give Five Minds For The Future a preliminary endorsement. The chapters on the disciplinary, synthesizing and creative minds are worth the purchase price alone.

There are some very sound observations on these cognitive outlooks on Gardner’s part – readers here will see vertical and horizontal thinking well represented, though Gardner eschews the use of those terms ( he does cite De Bono’s lateral thinking exercises). Mihaly Csikszentmihalyi is a strong influence on the creativity chapter though, as an aside, I do not always buy into Csíkszentmihályi’s social/collective/domain/peer ratification of creativity as a standard as Gardner does.
