Microevolution in Culture

I’ve been reading through Robert Weisberg’s (1986) Creativity: Genius and Other Myths and it occured to me that “the artistic process,” “the scientific process,” and “the writing process,” all follow the same process of creative problem solving, whereby there is an “ill-defined problem” that takes modification of past experience and knowledge to solve.

Weisberg intially provides the simple example of “the candle problem” where a subject is prosented with a box of tacks, matches and a candle, with the instruction to attach the candle to the wall, with the candle able to burn properly. Using verbal protocol, where subjects speak their thoughts aloud rather than describe what they’re doing, he found that most individuals start with directly attaching the candle to the wall with the tacks or by melting the base of the candle, and the more knowledable folk who can see that there are problems to that solution begin to reason the next best alternative to fix the problem in the problem, which is to tac the box to the wall as a stand.

Another example of creative problem solving is presenting in this type of riddle:

“Dan comes home one night after work, as usual. He opens the door and steps into the living room. On the floor he sees Charlie lying dead. There is water on the floor, as well as some pieces of glass. Tom is also in the room. Dan takes one quick glance at the scene and immediately knows what happened. How did Charlie die?”

The audience or subjects then try to guess the answer by asking yes or no answers, refining their questions to elicite the information needed to understand the riddle. Those who are good at these games have experience with problems of this sort.

Both of these are ill-defined problems because they are missing information. In non-creative problem solving, the answer is straightforward from the instructutions. Creativity is involved in answering ill-defined problems such as how well the wax sticks to the wall, or how strong are the tacks, or how old Charlie is, or how to model DNA or make sense of the natural world, or how to string a tune, or what connections to draw while writing a poem, what words to choose, or what happens next in a plot, or where the light falls in composing a painting.

Despite self-reports of an “Aha!” moment, or seemingly unconscious processes, Weisburg presents evidence for how the subjective experience is not the most reliable means for determining how the creative process actually works. The main reason is that artists and scientists often make such reports after the experience has long passed and memory can be faulty as one was more attuned to the task at hand than observing the whole situation. People will also (consciously or not) lie about their creative process, for “One can be influenced by a stimulus without being able to report it” (Weisburg 1986:29). The pleasure one gets from “Aha!” may just be relsease from consiously working on a hard problem for a long time, which is physically exhausting. Despite taking a break, creative people often engage in what Olton calles “creative worrying,” which is mulling over the problem even while not working on it, not an unconsious process. Breaks may also help the brain rest before having the energy to go at it again.

Genius looks like a divine gift from nowhere if one cannot see the small steps which it evolved from. This type of divine creativity coming forth perfected at once was never observed in laboratory settings, and careful examination of biographies, notes, sketches and drafts show that it takes hard work and at least ten years of training for the skill to contribute anything of value to that given field. A creative person draws from their exeperience, from the physical and cultural world around them. There are no correllations to be found in personality traits shared by all creative people. Creative people are also not creative in every field, nor is everything they produce a piece of genius. Weisburg writes, “Since the sensibilities of societies change, so do its judgements of genius… then looking at the characteristics of an individual, in order to determine the basis for genius, must be doomed to failure.”” (Weisburg 1986:88).

Master chess-players memorize thousands of chess positions (or approx. 50 000 patterns). Mozart’s later work is more popular to his early work; he too had to learn to compose. Picasso had sketches upon sketches of plans and edits of paintings, as do poets and composers who write pieces and try to fit them together, manipulating elements to solve a problem, to engage in critical anaylsis of their work. Great artistry does not come from a vaccum or perfected in the first coming-into-being. I think this is rather like how people viewed biology before evolution and genetics.

In any case, he is not saying the romantic view should be demolished, because it really does feel like an “Aha!” or something beyond your consciousness putting the pieces together. Objectively speaking however, the genius is a myth.

The romantic view, Weisburg defines, is the genius view that creativity comes through great leaps of imagination through communication with God or inspirational Muses. The behaviourist view is that creativity is nothing special because creative products are accidental combinations of old notions or knowledge.

Weisburg’s position lies somewhere inbetween. Small steps  rather than great leaps are the rule; here I quote:

“Harlow’s work indicates that insightful solutions of even seemingly simple problems depend on much experience with problems of that sort. Problems that appear to be trivially simple may only seem so because of the knowledge one brings to them. As Harlow’s work demonstrates, one should not underestimate the difficulties an inexperience problem solver confronts in a problem situation… Though someone else may solve a problem from what you consider a ‘fresh viewpoint,’ it does not mean the viewpoint was fresh from their point of view. If so, then trying to make oneself find that fresh point of view may be essentially impossible because it really means that one must transform oneself into another person, with that person’s knowledge, before one can bring a new approach to the problem. But then the viewpoint would not be fresh because one had acquired all that knowledge” (Weisburg 1986:48-69).

Creativity is ordinary, he argues, because the world changes. For example, if it was not Watson and Crick in that setting or scientific community, with that background or educational experience, working on that problem deemed to be a very important problem, and any one of those factors were changed, someone else would have discovered the two-stranded DNA helix, for they were not the only ones working on the problem. No environmental situation, perception of the situation and response to the situation will be exactly the same. Therefore it is a mistake to assume creativity is something humans do not engage with on an ordinary day-to-day basis. What we must explain then, is ordinary non-creative behaviour, when people engage in generalization and go through problem solving in a standard repetitive manner.

To summarize, Weisburg thinks creative individuals possess no extraordinary characteristics, “they do what we are all capable of doing. Because everyone can modify habitual responses to deal with novel situations, no further extraordinary capacities should be needed. Though in a given case the work and individual produces may be extraordinary, extraordinary work is not necessarily the product of extraordinary practices or the results of extraordinary personal characteristics” (Weisburg 1986:12). I think this speaks to the process of evolution being alive and well when we “create” culture, which appears extraordinary.

Non-biological evolution in the literature: Big review by Pagel 2009

Pagel 2009 Nature Rev Genet Human language as a culturally transmitted replicator

Mark Pagel (who is a phylogeneticist) reviews evolutionary modeling of languages, first comparing them to biological evolution (has a nice chart; disagree with a couple points though) and then discussing some recent examples of applications of evolution, including statistics (which should be much more oft used in the humanities, as it is by no means restricted to sciencey things!), phylogeny, analyses of evolutionary rates and evolution of language structures, etc.  The phylogeny section features a nice tree of indoeuropean languages, which looks eerily like Ciccarelli et al 2006 (NB: more updated tree of bacteria here: Wu et al 2009 Nature) In fact, I hijacked that detail for this poster that never got properly released…

The rate of word evolution section discusses an earlier study on lexical replacement being dependent on frequency of word use. Afterwards, Pagel discusses another study comparing language and species diversity and finding a curious correlation between the two (Which makes sense since environments favouring biological diversity may well also favour linguistic and cultural diversification). Then, he discusses the relationship and potential co-evolution of word order and pre- vs. postpositioning of modifiers. He also discusses word order changes and their evolutionary history revealed by phylogenetic analyses of various language families, which reveals interesting patterns like the instability of certain word order states. Pagel then wraps up the review by pointing out that languages, like genomes, have been subject to selective forces throughout their existence, and it would be interesting to investigate why some features, despite being possible, are never or seldom found compared to other features. Overall, this review shows there is ever-growing potential in this field, and hopefully it will develop into a proper science being done with the necessary caution, as opposed to the idle philosophising that plagues some corners of evolutionary linguistics…

(going section by section should help your paper reading+summarising as well…very nice of them to have headings!)

MURC Presentations

The short timeframe made it very difficult to present anything worthwhile in terms of content volume — stuff had to be extremely condensed at the expense of depth of ideas presented. The MURC timing didn’t help at all, but it’s very hard to get around it unless the term projects are assigned BEFORE the winter break! As with the rest of the course, it seems that to balance the problems from other classes toward the end of the term, much more work must be done in the beginning rather than end, leaving the rest of the term to polish off the paper. Hopefully MURC did help some of us with confidence in public speaking — my scarriest moment ever was at a professional conference, with my boss watching, but afterwards everything else seemed like a piece of cake, from 80min tutorial presentations to MURC (I was scared in my first one too!) and even just talking to faculty. Seems like public speaking requires some fear to be overcome one way or another… and like anything else, giving talks is an art that must be practised over and over again, with mistakes and the occasional embarassment, to improve.

Midterm Course Review

– I agree that there has been a bit too much administrative stuff, partly due to it being a first run of this kind of course, and partly as a result of overcompensation for my tendency to kind of dominate things too much. We were fed multitudes of scary stories during the training sessions about seminars rebelling against their coordinators and such (apparently true stories!), so we decided to take it easy with the rigidity of structure/planning. Of course, part of the price to pay for flexibility is time being spent on organising the course itself.

– The introductions/transitions could definitely have been better planned; was hard to see how to make them smooth during the first run.

– Coordinating becomes quite difficult towards the middle-to-end of term as other courses pile up, as does participating, of course. To soothe this, perhaps more assignments/parts of assignments and course planning done towards the beginning could help, as well as perhaps reducing the blog entries to once every two weeks, with or without topic questions. Unfortunately, one kind of has to get through the heavily-structured and condensed biology part of the course in the beginning, but prefacing it with a topical overview (as in the point above) could help. It seems like most discussion courses tend to get more flexible, and thus more effort-intensive, towards the end of term, simultaneously…

– As for the blog entries, it was difficult to think of stuff for me too, even though I blog science stuff publicly on a regular basis. Something about this being “informal-yet-formal” makes it still difficult to write stuff. Towards the end of term though, times get busy and probably would make sense to have the posts due less often than in the beginning.

Midterm review

Hm. The thing that pops into my mind first is that we spent a lot of time dealing with administrivia – I know with the fact that this is essentially a brand-new class, and student-directed at that means a lot of it is necessary, but I feel like it takes up more time than it needs to, and it eats into time for discussions and for presentations and guest speakers, all of which I’ve been really enjoying. I’m kind of on the fence about the blog posts – I do feel like they have potential to add a lot, but for some reason I have problems remembering to actually check and post and comment. I’ve been having this problem with the discussion boards for the online classes I’m taking, so…I don’t really know, here.

MURC Thoughts

MURC went…better than anticipated, at least for me. A lot of that is my crippling fear of public speaking – the fact that everything went relatively smoothly was very nice. Plus, I can’t say no to free food. Still, I agree with what others have said – the timing problem really screwed us up. And I think the timing of MURC within the year was bad for the course, too – if this had been a fall course, presenting would be fine, but it’s so early in second term, that I feel like I at least was still trying to figure out where I wanted to go with things when oh, hey, time to throw together a presentation, which sort of detracted on working on the paper and bigger-picture stuff.

MURC

I feel like I could have done a better job, personally, at MURC, but overall as a group I feel we did well. Next time, I think the entire research project should be brought up right away – we barely had any time to work on it before MURC happened. More time would have been good, and also maybe some prepared discussion questions for the audience at the end (well, and a longer discussion time at the end. I think people were a little surprised about it – since all the rest of the panels were basically mini-lectures and we were trying to get a discussion started!)

Midterm Thoughts

A general restatement of thoughts: A more thorough introduction tying all the subjects together and briefly explaining them at the beginning would be good. With the short presentations, I agree that the ones we’ve had so far have been scattered. Maybe it would be good to link them broadly to the current topic (as we’re doing from now on). So, one presentation for topics in biology, one for linguistics, and one for culture.

I can’t say I’ve really liked the blog posts. I always forget about them until right before they’re due, and stare blankly at the screen for a while before coming up with something I feel no one reads. Some guiding question might be good (though maybe they should be more suggestions than requirements). It might also be good to group every week’s posts into one thread, I’m thinking that might facilitate discussion more.

Also agreeing with preparing questions to asks presenters before they come in – and maybe having a bit more of an introduction as to who they are and why they’re coming in before they do. I dunno, I feel like this Thurday went really well, and I’m trying to figure what contributed to that. 🙂

Peter’s Midterm Thoughts

Honestly, I’d kind of like to see a bit more emphasis on absorbing the material; for my part, and I know this is my fault, I do feel like some of it just went in one ear and out the other. I know that short of marked evaluations (that I’m pretty sure everyone would like to avoid), there’s not much way to do this.
On that note, I do actually think the individual presentations have been fantastic, but would like to see more of them and a little more direction to those that happen. The ones we did were a little scattershot in terms of focus. This kind of ties back to the idea of me not really fully retaining the details of information presented in class. If we were required to present a couple times on subjects discussed in class, then it would focus us back onto the topics discussed and probably increase retention. Also, it would enforce the interdisciplinary nature of the course more, since we would have to take it into our own hands.
But the discussions we have are great and the points raised are provocative and interesting. It’s stuff that a linguist or a biologist would not normally be exposed to, which makes them all the more valuable.
Also, just as an aside that we may have talked about, I wonder how an econ major or a Business person would look at this course. I wonder how evolutionary thought would apply to different business models, successful and unsuccessful companies, that sort of thing.

MURC Week 6

Peter’s MURC Reflections

I think it was a great idea for us to present at MURC. Nerve-wracking? Yes. Supposed to be? Certainly! Only real problem I had was the marking based on visuals, but I think that’s for pretty obvious reasons.

That said, I’m going to stick with what I said in class in that I think more time would have been better for our talks; I realize we couldn’t get a single panel to be registered over two time slots, but maybe we could have registered in two parties? I don’t know, I’m just throwing ideas out there at this point.

Also, I would have liked a little more time in class to go over the presentations; I feel like even one more rehearsal would have improved things, since that would have been another set of comments to work with, particularly to see if there were any lingering issues.

Overall, though, I getting us to present at a conference was fantastic. But again, a little more class time (in all stages of the process) would have been good.
