Yesterday I had the privilege to attend an informative talk about effective communication by my friend and colleague Kevin Leahy, aka Knowledge Advocate. One point among many in Kevin’s talk: the content of a communication doesn’t matter as much as we think it does. Kevin, an attorney, said that post-trial conversations with jurors finds that they often recall little about what was said, but much about how they felt about witnesses, based quite a bit on their perception of body language. Coincidentally this morning I find an article about research, conducted by MIT political scientists, that shows how the appearances of politicians strongly influence voters, that people around the world have similar ideas about what a good politician looks like. [Link to the paper "Looking Like a Winner"  (pdf)] 

Sounds like you can take this to the bank: how you LOOK is important, and your BODY LANGUAGE is also important. What you think and what you say? Not such a big deal.

Another point, reading between the lines of the MIT Study: you’re better off if how you look is congruent with people’s perception of your role – there are definite stereotypes. If you don’t look like a politician but you have political ambitions, it’s better to work behind the scenes. (I think politicians already know this).

Ann Corwin created this terrific painting of Charles Babbage’s Difference Engine and posted it at her site, Existence is Wonderful. She’s using a color palette that fits the tones in her living room – I think it’s an effective interpretation.

More on Babbage and his machine here:

On Tesla’s birthday, Marsha and I were at a rousing Tesla Project art party featuring Arc Attack, a band that incorporates Tesla coils as part of the performance. Which is, naturally, electrifying!

Here’s some video I shot:

I spent today at the 2010 UTeach Conference here in Austin. UTeach is an acclaimed teacher prep program at the University of Texas. Attendees were mostly K-12 teachers and university professors from across the U.S. I heard about UTeach’s STEM focus (Science, Technology, Engineering, and Math), New Technology High Schools in Napa and Manor, project-based learning, Knowing and Learning in Math and Science, etc. I was primarily interested in the possibility of collaborative projects and learning involving multiple classrooms and disciplines, mediated by social technology. I was live tweeting the event. There were multiple sessions per time slot, so I only got a slice of it. (I also missed the events on Tuesday, and probably can’t make it tomorrow – so much more to learn about learning.)

I’ve often said that we don’t know enough about how peope behave online – e.g. how they read blogs or other web sites. Do we visit the same sites over and over again? Or do we surf, following links we stumble across as we wander, and now with pervasive social media, those that are posted on Twitter, Facebook, LinkedIn, etc.? More likely both – we have some sites we visit regularly, but we also bounce around a lot.

Behaviors are probably more complex than we think. Seth Godin writes that he learned, from Clay Shirky, of something called a Lévy flight: Example: “an animal that forages will hang out in a small area, looking for nuts or berries, then will realize it has used up all the likely sources in this spot. It will then head off in a random direction, walk many paces, and start foraging again.” The online version:

Someone discovers your site. They poke and prod and join and return and return again. Then they feel as though there’s no more benefit and they move on, surfing until they find another place to forage.

Godin calls this “a much more nuanced representation of consumer behavior than solely thinking about the ideas of brand loyalty or random web surfing.” But I’m enough of a nimrod to want to substitute the word human for consumer.

In creating with a history of the “climate fight,” Dr. Spencer Weart has created a history with interesting points about the democratization of knowledge. [Link] He talks about a decline in the prestige of all authorities, expansion of the scientific community with greater interdisciplinarity, and a decline of science journalism.

These trends had been exacerbated since the 1990s by the fragmentation of media (Internet, talk radio), which promoted counter-scientific beliefs such as fear of vaccines among even educated people, by providing facile elaborations of false arguments and a ceaseless repetition of allegations.

Mike Hulme’s response:

I think Spencer is helpful by suggesting there is a much bigger story happening in the world of science, knowledge and cultural authority of which the climate change incidents of this moment are just part. These are going to be increasingly difficult challenges for many areas of science in the future – how is scientific knowledge recognized, how is it spoken and who speaks for it, and how does scientific knowledge relate to other forms of cultural authority. It’s not just about the politicization of public knowledge, but also about its fragmentation, privatization and/or democratization.

In comments, Bob Potter says

The key phrase is “expert public relations apparatus”. In the mid 20th century scientists had the luxury of public respect. People believed what they said. As public confidence in authority figures of all types waned, scientists took no notice. When global climate change became a serious issue scientists still assumed that a “word from the wise” would be sufficient, and that is all they brought to the fight. They lost the war because industry had a public relations army and they did not.

All great points: we’re in the midst of culture and information wars, and the concept of “authoritative voice” is less meaningful, if not lost. We can’t fix this by going backwards… as so many of us have said before, we have to focus more than ever on media literacy. Should be right up there with reading, writing, and arithmetic.

Joel Makower considers four studies that explore the impact on business of climate change and related issues – the need for water management, and uncertainty about energy sources. Says Joel, “our world these days seems to be a succession of forks in the road, points at which decisions need to be made about which pathway we collectively must take.” This reminds me of something Rod Bell used to say, repeatedly: “To solve big problems, you have to go through big confusion.” [Link]

I’ve often wondered whether insects are more intelligent than we think. A Science Daily article suggests that “tiny insects could be as intelligent as much bigger animals, despite only having a brain the size of a pinhead.” The article goes on to say that brain size is not predictive of intelligent behavior, that “bigger animals may need bigger brains simply because there is more to control.” Lars Chittka, Professor of Sensory and Behavioural Ecology at Queen Mary’s Research Centre for Psychology, says “In bigger brains we often don’t find more complexity, just an endless repetition of the same neural circuits over and over. This might add detail to remembered images or sounds, but not add any degree of complexity. To use a computer analogy, bigger brains might in many cases be bigger hard drives, not necessarily better processors.”

Synthetic biology is riff on nano/bio tech – according to Rudy Rucker, “it’s about building slippery wetware entities that might live in the real world.” Rucker has a rich post about the field, and its promises (“we ought to be able to design some kind of microorganism that eats
inexpensive crud and generates energy in some usable form or another”) and problems (“what’s to stop a particularly virulent synthetic organism from eating everything on earth?”) Ending with a cool science friction premise:

Suppose it were possible to encode a person’s memory
and personality into a single, very large, DNA-like molecule. Now
suppose that someone turns himself into a viral disease that other
people can catch. If I were you—sneeze—oh, wait, I guess I am.

Gesundheit.

Earth observers used to think that Mars had canals, but this is even better: weirdly interesting darker trails in the Martian sandscape, created not by bug-eyed Martians on four-wheelers, but my dust devils up to 8 kilometers high. High res image and more information here.
