Rational Philosophy

New findings of brain research, exoneration through DNA analysis, and relationship twists.

My four year-old son gloms on to new interests with great intensity and with a level of focus that seems infinitely unflagging. Depending on the interest, his mother and I either rejoice (relatively speaking) at his fascinations, or despair. But neither state lasts long. Just when we think he’ll be a Thomas The Tank Engine junky all his life (despair!), he moves on to Lightning McQueen (better). And as we begin to worry that he’s reciting all the words to the Cars movie, he drops that and moves on superheroes. Now we’re anxiously awaiting the next new thing while we try to figure out how to dissuade him from wearing his superhero costumes — complete with capes and masks — everywhere he goes.

For children, new habits are old hat. But as we grow to adulthood, we tend to narrow our focus and stick to things we feel comfortable with. But according to research findings (and this one passes the ‘duh!’ test) when we stretch ourselves and try new things, form new habits, we create new pathways in the brain, and even new brain cells, that can lead to innovative thinking.

The NY Times article is light on references, but points to a couple of interesting concepts:

1. That research in the 1960s indicated that we’re born with the capacity to tackle challenges in four primary ways: analytically, procedurally, relationally (or collaboratively) and innovatively.

2. That when we reach puberty our brains tend to close off half of that capacity, maintaining the approaches that have worked best for us so far.

These seem like very dubious claims. I’ve always felt that true analysis has to begin with innovation. Sure, spoon fed bookwork can be achieved with almost no innovation — if we’re told to tackle a problem in a certain way — but if we’re faced with a true challenge, one that comes without a prescription, don’t we have to think innovatively in order to get the analytical ball rolling?

So, I take these strict categorizations with a large grain of salt. But I do like the idea of challenging ourselves to forge new pathways in the brain. And the more that I read about the studies in this area, the more excited I become about the prospect that people can change the way they think. (See Irony And The Plastic Mind and The Promise of The Plastic Mind.) We can respect the idea that we approach challenges with some mix of analysis, procedure, collaboration and innovation, even if we don’t consider them mutually independent strategies. And this gives a new dimension to our habit experimentation — if we tend to do a lot of things heavy on analysis, try something that’s heavy on innovation…

NPR reports on James Lee Woodward, the 17th Dallas man to be exonerated by DNA evidence. Woodward had spent 27 years behind bars, even forgoing chances of parole because he wouldn’t apologize for a crime he didn’t commit. The new Dallas DA — Craig Watkins — is determined to reexamine as many dubious convictions as possible in order to get the innocent out from behind bars. At an institutional level Watkins has begun to institute new habits of fairness and due process in the DAs office. And this seems to be a very important connection between these two articles. Just as we can stretch ourselves on a personal level to get ourselves out of a rut, to challenge ourselves to think more innovatively, so, too, the same thing can and does happen with society.

Institutions, after all, comprise people, people doing what they’re accustomed to doing, and what they are told to do, or implicitly or explicitly encouraged to do. It is the Craig Watkins of the world who act as catalysts for change within our institutions. (Sadly Watkins success at overturning old convictions with DNA evidence can’t be replicated in other parts of Texas — everywhere else the DNA evidence of these old cases has been discarded.)
(Of course, not all change is positive. The Bush administration has provided a striking example fo change for the worse, creating an institutional mindset in government that has set the country back several decades in terms of enlightened national and global policies.)

Coincidental to the main theme of this post, I came across an article on CNN.com that dips into the things that can happen in relationships when one partner makes a big change. The report gives several examples — the man who encourages his wife to become a nudist, the woman who ditches her fiance when he quits his high power job, and the man who loses his wife when he tells her he’s a cross-dresser.

What’s interesting about the CNN article vis a vis this post is that it points to a subtle way that we can forge new pathways in relationships just by being ourselves, by accepting our desire for something and being honest about it. Interestingly, the relationship experts don’t seem to unreservedly endorse honesty and self-expression. There’s a bit of finger-wagging going on. But in each of the three examples I found it hard to see that the relationship would be worth salvaging if it couldn’t survive the new challenge at hand.

I’ll end with the words of James Lee Woodward: “Time is what you make of it. You’re living no matter where you are.”

Changing the way we think.

Last week I wrote about the implications of what happens to an animal’s brain when you teach it to use a rake. I was fascinated and excited by the idea that the brain’s genetics may be changed by the way it is used. What might this tell us about our capacity to change the way we think and react?

Sandra Aamodt and Sam Wang write today about the brain’s limited capacity for governing self-discipline. Research going back several years has shown that if you exercise restraint or self-discipline in one activity or area of your life, you will deplete your “self-restraint” resources and find it more difficult to remain disciplined in another activity. Complete a cross-word puzzle and you won’t be able to resist dessert.

The studies implicate blood sugar as an important factor in restoring or maintaining self-restraint. Subjects performed better on disciplined tasks if they were allowed to replenish their blood sugar between those tasks. (If only Spitzer had had a glass of lemonade after a hard day in the legislature!)

But most fascinating for me the research has shown that one can increase one’s self-discipline over time by exercising it. This likely (the article says “must”) reflects “some biological change in the brain.” “Even something as simple as using your nondominant hand to brush your teeth for two weeks can increase willpower capacity.”

David Brooks uses insights from sports psychologist H. A. Dorfman’s book The Mental ABC’s of Pitching to argue that the prevailing American emphasis on self-awareness and self-discovery has begun to shift back toward self-discipline and the idea of transcending onesself in one’s work. Brooks, not unusually, doesn’t provide any kind of specific context for his assertion, but his unearthing of Dorfman’s ideas proves a fortuitous coincidence.

Brooks quotes from Dorfman’s book: “Self-discipline is a form of freedom. Freedom from laziness and lethargy, freedom from expectations and demands of others, freedom from weakness and fear — and doubt.”

Combine this idea with the concept that we can, by exercising willpower and self-discipline, increase our capacity for it, and we have an even more powerful idea: we can choose to free ourselves from habits that inhibit our performance and self-satisfaction.

People, particularly young people, tend to rebel against the idea of excessive self-discipline. Too often the concept is fused with the idea of mindlessness or blind adherence to rules. Discipline can seem antithetical to freedom.

But we can distinguish between a reflexive adherence to habits, rules and regulations and the choice of adherence for the sake of improving self-discpline. One is passive and undirected, the other active and end-directed.

According to Dorfman, and supported by scientific research, it makes no difference whether we feel, in the moment, that we want to exercise self-discipline. If we act in a self-disciplined way we will increase our willpower. Just as we go to the gym to workout, whether we feel like it or not, we might be much more inclined to exercise self-discipline if we understand that it will make it easier for us to exercise more self-discipline in the future.

The same philosophy applies to other brain functions. If macaques and rodents in learning to use a rake exhibit changes in brain DNA, then we can postulate that people can experience changes in brain DNA by stretching the use of our minds.

(This theory comports with common sense (sophisticated mental tasks seem to make people more capable of performing sophisticated mental tasks) and studies that show brain exercise is linked with mental health in later life.)
