Daemon by Daniel Suarez

I was not entirely happy with the amount of book reading that I accomplished in 2009 and this year I am going to shoot for both a larger number of books as well as more books that are fiction or relate to science. In this instance, both.

I picked up Daemon because of the exceptionally high praise given to Suarez’s new book, Freedom
TM
by John Robb and Shlok Vaidya (Freedom is the sequel to Daemon and Robb has a blurb on the book jacket). They were right. Suarez is good. As in William Gibson good. Orson Scott Card good. Philip K. Dick good. You get the idea.

Elkus on Science, Defense and Strategy

Friday, January 8th, 2010

My amigo Adam Elkus has an excellently constructed and well researched article up at OpenSecurity where he advances a Boydian critique for what ails us:

Science, defence and strategy

…Contemporary American strategic problems flow from the fact that we cannot adjust the ossified thinking of Washington D.C. to the constantly shifting observed reality of the outside world. A failure to match concepts to observed reality has amplified the already formidable entropy of the American political system. The corresponding failure to make strategy results in a search further inward towards the “science” of war.  Better strategy will come about only when the process by which strategy is made becomes supple, flexible, and less dominated by sacred cows and special interests.

Critics of American foreign policy often undermine their own case with conspiracy theorizing about the “military-industrial complex.” The real problem, however, is not James Bond villain-style secret plans and hidden agendas but basic human frailty. A largely homogenous group of people is not going to have all the answers to questions of war and peace because they are necessarily limited by their experience, specialization, and biases.

Nice work by Adam, read the whole thing here.

We face a number of problems when it comes to formulating strategy and grand strategy. Not least is that, whatever the shortcomings on that score within America’s officer corps, there is a yawning gap of comprehension between the senior brass and most of the civilian “influencer” elite in and out of government. Most of the latter tend to think in terms of a few simple paradigms into which they force-fit each new foreign policy problem – generally, everything is conceived either as appeasement at Munich or the quagmire of Vietnam. This tiresome dichotomy is the strategizing of simpletons.

The arch-Clausewitzians in the national security community fall down here. It is not enough to think of strategy in purely military terms. America is not Sparta or even the Roman Republic where politicians vied for a chance field command. The civilians here are masters of policy and the military are its servants – and are but one kind of servant among many in the DIME spectrum. Statesmen and general officers need to be speaking with a common vocabulary and have a shared understanding of what strategy is if we are to formulate effective ones.

There is a deficit of knowledge among the class of officials and staff members with the authority to make or not make the most critical decisions in matters of peace and war. It cannot be remediated by an uncertain and unhealthy dependency on the Pentagon’s advice and a frustrating dialogue where civilian and soldier talk past one another.

Cognitive Reflections Part II.

Monday, January 4th, 2010

There have been some thoughtful posts on visual thinking lately which (according to Wikipedia) is the dominant form of thought for 60-70% of the population. I am somewhat skeptical of that unsupported figure because many people report thinking in a combination of words, images and other nonverbal prompts but I can accept that the percentage, whatever it may be precisely, is significant. Here are the posts:

Dr. VonImportance of Imagery for Memory & Learning

Austin KleonVISUAL THINKING FOR WRITERS: NOTES AND SLIDES 

Gerald GrowThe writing problems of visual thinkers

On a related note, a while back, Dave Schuler and I, along with Dave Davison, had some exchanges on “visualcy” that are also worth consideration:

Dave Schuler“I Can Read a Passage in a Book 20 Times and It Doesn’t Click”, More On Visualcy, The Visual Imagery Society, cognitive reliance on visual media:

ZPOn the Virtues and Vices of “Visualcy”, Visualcy and the Human Terrain

Dave DavisonMuralCasting – Improving ROA (Return on attention) -corrected 2.8.08 , Logic + Emotion: Developing an Experience Strategy in 4 Parts, Too many ripples in the pond?

Visual imagery is exceedingly powerful on a neurocognitive level, even with populations that are highly educated and predisposed to think in words and therefore, lends itself well to disinformation, propaganda, IO, advertising and mundane distraction and wastage of time. “Surfing the web” is a visual activity, albeit one that can involve a good deal of reading but ultimately sites like youtube have a definite advantage in attracting and holding attention. Usually to no productive purpose.

On the other hand, I would like to suggest that visual imagery or thinking in pictures is a critical component of insight. We like to use the term “visionary” to describe a trailblazing genius in some field and it is an apt description. Many an empire or artistic acheivement or intellectual discovery was crystalized as a hazy image that served as a template within which many future problems, known and unknown, could be addressed successfully. Or be refined and extrapolated in a tinkering, tweaking manner by trial and error by individuals or groups over time. Imagery can also be a useful starting point for strategic thinking in the form of brainstorming conceptual outcomes.

Furthermore imagery can be used as a “bridge” to improve the comprehension of difficult concepts and make learning more efficient. Dr. Von explains:

….For readers, 60% of 5th graders report naturally using some imagery during ‘think aloud’ breaks in reading stories. It appears to be a natural reaction, even for children, to try and ‘see’ the scenes that words are trying to convey in order to develop memories of a story that we, ourselves, are not part of in reality. Humans are more visual creatures, as I like to tell my own students, and it is important to remind and also teach students how to visualize physical events and experiences. In fact, in problem solving in physics, I try and teach as an essential part of every single problem to draw a picture and mentally ‘see’ what is happening in the problem. We use a technique that requires making pictures and labeling all forces on the picture, and then use the picture to actually set up the math (for F = ma problems). So science and imagery are naturally connected, just as reading, writing and imagery are connected. Memory improves when visualization and imagery are used for stories or for how physical events play out in reality. The experimental finding that a good majority of the brain used for the physical activity is used in imagery, too, begins to explain why this process works.

This is a great example of using imagery as a tool toward a calculated end rather than having imagery overrule or hijack the rational faculties ( which may be the majority of the time when imagery is involved). We should respect the power of visual imagery in cognition when considering the impact on our own thinking but we should not fail to exploit the opportunities the use of imagery can provide.

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.
