Drawing on the Right Side of the Brain

My girlfriend Gretchen has been working through Drawing on the Right Side of the Brain by Betty Edwards, and she decided to write a blog post about it.  I understand that “left” and “right” brain designations are somewhat outdated.  But there does seem to be some sort of mapping between the idea of an intuitive right brain and Kahneman‘s idea of System 1, while the rational left brain maps to System 2.

I haven’t read Edwards’ book myself, but one key idea that jumps out is that our preconceived notions of the things we are seeing can prevent us from perceiving them accurately.  This idea has been borne out somewhat by those transcranial magnetic stimulation experiments where subjects are able to draw much better when their left anterior temporal lobe is temporarily disrupted.  Though in those experiments they appear to be drawing from memory instead of from life, so this connection may be tenuous.

But this poses an interesting problem.  We seem to need abstractions of reality in order to reason about it, but these abstractions necessarily discard information.  The map is not the territory and all that (though reasoning (rationality) is not the sum of cognition).  Get Monica Anderson on the phone!  She loves these holism/reductionism quandries.  Of course the radical enactivists would have us discard the idea of cognition as representation altogether.  So they might deny something at the very heart of the map/territory argument: cognition requires representation.  I have to look up the enactivist take on rationality.  But they do love the idea that perception is self-directed.  It’s probably useful to keep in mind that our own conceptual frameworks are continually constraining our vision.  Though we may or may not be able to avoid that entirely.

Jersey Shore is better than cat burning.

I met a friend for a chat this evening and we walked down Piedmont avenue having the aristocrat vs commoner argument.  I am not sure I fully understood his position, but it seemed to be that something was lost as the European landed aristocracy was supplanted by democracy.  Sophisticated statescraft honed across centuries was cast aside and replaced with what? (cough – there used to be two new wars a year there, for 600 years)  Democrats are nothing but unwashed merchants and tradesmen with no sense of decorum.  I have had a similar argument at the Less Wrong party before the Singularity Summit.  One fellow there was arguing that democracies have led to a spiritual decay.  I get confused when these hard rationalists start throwing the word “spiritual” around so I asked for clarification.  Another participant supplied this example: Spirituality is the idea that Wagner is in some way superior to Britney Spears.

Ah, these reactionaries, they do strike a chord don’t they?  This recollection recalls to mind the great Moldbug-Hanson debate of Foresight 2010.  Moldbug said bring back the monarchs (Steve Jobs for Dictator!) and Hanson said let the markets rule us.  I guess I have to side with Hanson’s markets though my heart more truly lies with the democrats throughout history who have distributed the decision making power beyond the elites.  But I digress from my digression.

As we walked down Piedmont avenue this evening, the topic turned to Culture.  “Surely no artist today could match the majesty of the Sistine Chapel?” my friend asked.  So we have lost something.  Well I guess that’s true, but the sponsors of this wondrous propaganda piece also gave us the charming Inquisition:

for punishment does not take place primarily and per se for the correction and good of the person punished, but for the public good in order that others may become terrified and weaned away from the evils they would commit

Good stuff.  Besides, I haven’t seen it in person, but that Sistine Chapel art doesn’t really speak to me. I don’t much go for that tacky Italian stuff with panel mushed upon panel and every nook and cranny bursting with cherubs and whatnot.  And I have some reservations about this God fellow that plays a prominent role.   What about us humans down here?  I can’t get into classical music much either, certainly not that overblown Wagner stuff.  I might literally prefer Britney.  I can handle a nice mellow Brahms sonata here and there, but since we can still access classical culture, what have we really lost?

Art should give expression to those things we are feeling but cannot express.  “Are we so stunted emotionally?” asked my friend?  Yes!  Those of us who cannot paint or dance or write literature or play music are all stunted.  We cannot express ourselves in these media, so the artist that shows us something we can relate to in film or music or art has given a new voice to our yearning and suffering and joy.  This is a gift of illumination.  Damn, it makes me want to go look at art or something.

That’s when a bunch of Mills College students butted into the conversation.  Some lamented this loss of culture, others saw a paternalistic threat in this yearning (justified or not.)  One young woman (who I will call the Liberal) brought up the good point that great art is certainly being made now, but we can’t see which of it is timeless until it’s been tested by time.  She did mention Coltrane as a likely candidate.  Certainly some scribblers worthy of note have emerged in this uncouth age.

The Liberal’s sparring partner (the Conservative) countered that we are isolated from one another and distracted by trivialities like “Jersey Shore.”  So we can’t talk to one another and our attention spans have decayed to 140 characters.  The Liberal defended the great pluralism of the USA and pointed out that she saw the Conservative take part in the community of a music show.  I agree with this. At one time no peasant could travel more than 20 miles from their place of birth.  They had no choice but to accept the religion and culture of their village.  But today we have the freedom to go and find our own intentional communities or just Futurist meetups as the case may be.  Sure the old culture offered comfort, and freedom is hard but the old cultures mostly sucked actually.

Take genital mutilation.  That’s cultural.  I place it right along side of the Sistine Chapel as an example of culture.  Most of the Mills Students agreed that we need to take the good and leave the bad behind in regard to the old cultures.  But I wonder how divisible cultural artifacts truly are.  Is the Sistine Chapel integrally linked to oppression and Inquisition?  Can the beauty really be expunged of the horrors that funded it and the message it inheres?  Some things were lost with the passing of Culture.  Some horrible things along with the great.

No, things are not perfect now.  I am not thrilled that half the world still lives on less than $1,225 a year.  Call me a Whig, but I am with Pinker on the whole progress thing.  Sure Jersey Shore plays on our primate need to determine the status of others, but it’s a hell of a lot better than burning cats for entertainment.

Samuel Arbesman at Long Now

Samuel Arbesman gave a talk on his new book “The Half LIfe of Facts” at the Long Now museum tonight.  This is a good venue to hear authors speak.  It is quite intimate and there are generally plenty of good questions and discussions afterward.  Arbesman did a good job of fielding comments from the  group.  You can see his presentation style in this short video.

His thesis is that there is an order and regularity  to the way knowledge changes.  He thinks that studying this can help us order the knowledge around us.  Because of this change, we should expect some portion of the facts we take for granted now to be overturned.  He points out that doctors are taught in medical school to expect their field to change and journals such as UpToDate provide this service to help doctors keep track of changes in medical knowledge. (My personal experience makes me skeptical that many doctors actually take advantage of this sort of thing.)

Arbesman takes the position that we would all benefit from this approach to learning.   We should learn how to think and how to understand the world but treat education as a continuing process.  Which is something I tried to touch on before.  Arbesman did comment that it’s better to rely on Google for current information than memorize a bunch of facts that may or may not continue to be true.  This takes me back to the ideas of Madeline Levine who I’ve mentioned before.  She argues that children should do less homework and more play because that builds creativity and problem solving skills.

Another point Arbesman brought up was that there is so much knowledge now, that many correlations can be discovered by mining the existing literature and joining together papers that each solve some fraction of a problem.  A speaker at the CogSci conference in 2010 at UC Berkeley mentioned that many answers probably go unnoticed and uncorrelated in the literature.  One effort to start detecting these hidden relations in the bioinformatics field is CoPub project which is a text mining tool developed by Dutch academics and researchers.  Theory[Mine] does an amusing take on this idea by letting users purchase a personalized, AI derived, unique, and interesting theorem.

Arbesman also suggested that facts in the hard sciences are subject to longer half-lives than facts in biology and the half-life decreases even further for the humanities and medicine.  He mentioned that when physicists colonize other fields they are unpopular and create disruption, but that they bring in useful ideas.  But I wonder if it’s even theoretically possible to reduce sociology to physics.  This is the whole holism/reductionism dichotomy that Monica Anderson loves to explore.

Another point that came up was that while the idea of fact decay should encourage healthy skepticism, we should still try to avoid unhealthy skepticism.  During the question and answer session it was suggested that politically controversial topics such as evolution, global warming, and even GMO labelling are clouded with incorrect facts.  I think a lot of scientists get a little overly defensive by what they term as anti-science policy decisions and they might be incorrectly grouping GMO opponents in with the creationists and global warming denialists.  Hopefully, better understanding of fact decay will radiate out and attenuate some of the scientific hubris out there.
