Very, very busy but the following two items struck me as useful advice for sharpening our mental edges.

First, John Robb linked to a series of posts by Eric Drexler of Metamodern. Al of them were good but I particularly liked the following one:

How to Understand Everything (and why)

….Formal education in science and engineering centers on teaching facts and problem-solving skills in a series of narrow topics. It is true that a few topics, although narrow in content, have such broad application that they are themselves integrative: These include (at a bare minimum) substantial chunks of mathematics and the basics of classical mechanics and electromagnetism, with the basics of thermodynamics and quantum mechanics close behind.

….To avoid blunders and absurdities, to recognize cross-disciplinary opportunities, and to make sense of new ideas, requires knowledge of at least the outlines of every field that might be relevant to the topics of interest. By knowing the outlines of a field, I mean knowing the answers, to some reasonable approximation, to questions like these:

What are the physical phenomena?
What are their magnitudes?
What are their preconditions?
How well are they understood?
How well can they be modeled?
What do they make possible?
What do they forbid?

And even more fundamental than these are questions of knowledge about knowledge:

What is known today?
What are the gaps in what I know?
When would I need to know more to solve a problem?
How could I find it?

It takes far less knowledge to recognize a problem than to solve it, yet in key respects, that bit of knowledge is more important: With recognition, a problem may be avoided, or solved, or an idea abandoned. Without recognition, a hidden problem may invalidate the labor of an hour, or a lifetime. Lack of a little knowledge can be a dangerous thing.

Secondly, reading through Richard Nisbett’s Intelligence and How to Get It: Why Schools and Cultures Count ( see this monster, two-part, book review by James McCormick at Chicago Boyz), the intriguing findings of the “Venezuela Project” run by none other than the late Richard Herrnstein of Bell Curve fame. Nisbett writes (74-75):

Herrnstein and his coworkers devised a very advanced set of materials geared to teaching seventh-graders fundamental concepts of problem solving that were not targeted to any particular subject matter. In effect they, they tried to make the children smarter by giving them handy implements for their intellectual tool kits.

What were those non-subject specific, cognitive skills?

• Basics of Classification
• Hypothesis Testing
• Discovery of Properties of Ordered Dimensions
• Analogies
• Simple Propositions
• Principles of Logic
• Constructing and Evaluating Complex Arguments
• Weighing opportunity costs vs. probability of success for a goal
• Evaluating credibility and relevance of data

I would have added metaphors, pattern-recognition and intuitive thinking games but it was a fine set of skills and the results were remarkable, according to Nisbett:

The instruction resulted in big changes in children’s ability to solve problems that the new skills were designed to improve….for language comprehension, .62 SD [ standard deviation]; for learning how to represent ‘”problem spaces,” .46 SD; for decision making, .77 SD; for inventive thinking, .50 SD. In short, general problem solving skills can be taught, and taught moreover in a brief period of time.

In psychometric terms, for a 13 year old, these scores represent phenomenal improvements in cognitive performance and indicate the plasticity of some aspects of measured intelligence. Why have such activities not become commonplace in public schools? Or universities?

Why indeed?

More fodder for the digital vs. dead tree debate:

UCLA Study: The Internet Is Altering Our Brains

….After the initial brain scan, subjects went home and conducted Internet searches for one hour a day for a total of seven days over a two-week period. These practice searches involved using the web to answer questions about various topics by exploring different websites and reading information. Participants then received a second brain scan using the same Internet simulation task, but with different topics.

The first scan of participants with little Internet experience showed brain activity in the regions controlling language, reading, memory and visual abilities. The second brain scan of these participants, conducted after the home practice searches, demonstrated activation of these same regions, but there was also activity in the middle frontal gyrus and inferior frontal gyrus – areas of the brain known to be important in working memory and decision-making.

….The results suggest that searching online may be a simple form of brain exercise that might be employed to enhance cognition in older adults,” Teena D. Moody, the study’s first author and UCLA researcher, said in a statement.

When performing an online search, the ability to hold important information in working memory and to take away the important points from competing graphics and words is essential, Moody noted.

I will be interested in seeing brain scan comparisons between digital natives who were on computers from the time they were toddlers, and the digital immigrants.  My son, for example, learned to read on his own long before pre-school from looking at words on a computer screen ( less “learned” than spontaneously “realized” the symbol-sound-conceptual connection ) while his sister, who had a more traditional exposure to reading, learned later ( more “taught”).

Another difference, while they are both equally skilled at reading, adjusted for an age, she is an avid reader who devours large books (mostly fiction) while her brother reads instrumentally, for knowledge or expository explanations (mostly natural science subjects. Only “Clone Wars” attracted him to read fiction).

Jeff Stein of Spy Talk had a fascinating interview with Dr. David Charney, a CIA psychiatrist specializing in treating professional spooks. The whole article is interesting but the following caught my eye:

….But for case officers at the tip of the CIA’s spear, he said, the problem tends to be A.D.D., Adult Attention Deficit Disorder. 
“They seem to be highly functional A.D.D.’s,” Charney said. “You might think a person with ADD can’t tie their shoelaces, but quite the opposite.” To them, “boredom equals death,” Charney says, not really joking. 

“They’re energetic, restless, people who have to physically keep moving. Lock them to a desk, and they can’t deal with it. They can’t stand to be bored…” 

But A.D.D. can be an asset, too.  “They have the ability to absorb things from 360 degrees,” Charney marvels. 

“Contrast that with people who are linear, like your book-keeper or accountant, who chug along in a channel and get things done by going from one thing to another. But A.D.D. minds tend to be very synthetic. They reach out and pull things out of the air, or through other persons who are not linked in any way. They see patterns that other people don’t see. They can gather together unusual elements and bring them together into a whole that is a brilliant synthesis of things that would be lost on other people.  

“They have a sensitivity to ambient thoughts going on that a good case officer needs to pick up, little nuances, little hues, little things said that let you know if the agent you’ve recruited is telling the truth, or which is partly the truth … which buttons to push to manage the person, how to absorb material and put it into a whole. And the good ones have that ability.”

This is classic horizontal thinking with an emphasis on connections, patterns and synthesis driven by an internal “restlessness” – the kind of persona seen in such disparate occupations as fighter pilots, inventors, physicists and artists. There has long been a comparative and to an extent correlative association of ADHD or “hyperactivity” with creativity, high levels of intelligence and depression though of course not everyone with ADHD is creative, intellectually gifted, depressed or working for an intelligence agency. The correlation though has also been noted in MRI brain scan studies of children so it would appear to have a physiological basis that might explain why the CIA needs to have its own psychiatrists for reasons beyond the stress generated by a career in intelligence work – self-selection bias in people who apply to become employees.

(Hat tip to….one of my twitteramigos….I can’t find the tweet, damn it!) 

I’m as big a fan of technofuturistic science as the next reader of Danger Room but National Defense Magazine ‘s article really is breezily optimistic:

Reverse Engineering the Brain May Accelerate Robotics Research 

….Machines that walk upright will assist civilians and the military alike, said Stefan Schaal, associate professor of computer science and neuroscience at the University of Southern California.“We should at some point be able to create an artificial human being and I think humanoid robots are currently the first step toward that,” he said at the Army Science conference.“This is going to happen,” he predicted. “And it’s going to happen in this century.”It may not be as “polished” as the iRobot movie, he added.While other experts noted that there are huge technological hurdles to overcome, basic research continues on several critical technologies such as vision, movement and computational models that will allow robots to “think” like humans.A parallel effort to map – or reverse engineer – the human brain is going to give robotics experts inspiration that will allow them to create these advanced models, researchers at the conference said.The National Academy of Engineering is spearheading this “Grand Challenge.” Just as researchers successfully mapped the human genome earlier in the decade, the engineering community – not normally thought of as being a part of the life science discipline – says there will be a clear benefit to a Herculean effort to figure out exactly how the human mind works.“If we could determine the software of the human brain, we could embed all sorts of systems so as to provide human like quality for machines,” said John Parmentola, director of research and laboratory management at the Army office of the deputy assistant secretary for research and technology.Neural models will enable robots to better perceive, think, plan and act, said James Albus of the Krasnow Institute at George Mason University, Va.

“Significant economic and military applications will develop undoubtedly early in this century and in fact are already developing,” he said.

The part that makes me a tad skeptical is the “reverse engineering” of the brain. This is no small task. “Wetware” isn’t hardware and the wetware here is dynamically adaptive and to an extent individualized within parameters we do not yet fully understand. Unless I am missing something ( please correct me if I am) in terms of difficulty, reverse engineering the brain would appear to be harder than almost any other question that could possibly be related to the whole field of robotics itself. 

While scientists have learned more about the human brain in the last 10 years that the previous 10,000, brain science is still in it’s infancy. The exciting MRI scan studies are primarily exercises in positively identifying correlation of brain activity with specific cognitive and physical tasks; what these studies mean in terms of application requires extrapolative speculation and experimentation.

By all means guys, go for it! I’m behind the effort 100 % as the spillover benefits are going to be enormous. However, I’d wager that this strategy is not the fastest route to functionally useful, autonomously acting, robots on a societal scale.

ADDENDUM:

I just picked up P.W. Singer ‘s new book Wired for War: The Robotics Revolution and Conflict in the 21st Century.  Flipping through it quickly, I will say this is an extremely cool book designed to appeal to war nerds, tech geeks and defense policy wonks alike ( For example, if you read Singer’s ref to “the Big Cebrowski” and get it, well, then this book is for you). Some well known figures in the blogosphere also make it into Singer’s book but to find out who, you’ll have to go get a copy. 🙂

ADDENDUM II. 

Jeff Hawkins at TED.com on the revolutionary potential of brain science:

Here’s an interesting bit of research: the human brain appears to have a serious bias toward hierarchical structures that makes issues of status and rank a distracting and destabilizing variable:

Human Brain Appears “Hard-Wired” for Hierarchy

Human imaging studies have for the first time identified brain circuitry associated with social status, according to researchers at the National Institute of Mental Health (NIMH) of the National Institutes of Health. They found that different brain areas are activated when a person moves up or down in a pecking order – or simply views perceived social superiors or inferiors. Circuitry activated by important events responded to a potential change in hierarchical status as much as it did to winning money.

“Our position in social hierarchies strongly influences motivation as well as physical and mental health,” said NIMH Director Thomas R Insel, M.D. “This first glimpse into how the brain processes that information advances our understanding of an important factor that can impact public health.”

… “The processing of hierarchical information seems to be hard-wired, occurring even outside of an explicitly competitive environment, underscoring how important it is for us,” said Zink. Key study findings included:

• The area that signals an event’s importance, called the ventral striatum, responded to the prospect of a rise or fall in rank as much as it did to the monetary reward, confirming the high value accorded social status.

• Just viewing a superior human “player,” as opposed to a perceived inferior one or a computer, activated an area near the front of the brain that appears to size people up – making interpersonal judgments and assessing social status. A circuit involving the mid-front part of the brain that processes the intentions and motives of others and emotion processing areas deep in the brain activated when the hierarchy became unstable, allowing for upward and downward mobility.

• Performing better than the superior “player” activated areas higher and toward the front of the brain controlling action planning, while performing worse than an inferior “player” activated areas lower in the brain associated with emotional pain and frustration.

• The more positive the mood experienced by participants while at the top of an unstable hierarchy, the stronger was activity in this emotional pain circuitry when they viewed an outcome that threatened to move them down in status.  In other words, people who felt more joy when they won also felt more pain when they lost.

“Such activation of emotional pain circuitry may underlie a heightened risk for stress-related health problems among competitive individuals,” suggested Meyer-Lindenberg.

With such a strong intrinsic reward system, the incentives for maintaining high status in an organization would outweigh those involved in carrying out the organization’s core mission – i.e. ” leaders” have a built-in drive to maintain the status quo at the expense of any possible nominal objective. The predisposition would also be present to look for hierarchical couterparts that do not exist in adversarial organizations that have a network structure and to ” sabotage” networked and “modular structures” on our own side in order to transform them into a hierarchy than can better fulfill the ego-needs of a “high status” individual.
