Framing Embeds Values in Scientific Facts

At the Sustainability Symposium last night (which was nominally about water footprints (PDF) and this paper on the international trade in virtual water) we ended up “off topic” and talking about science communication, public outreach, and how policy gets made.  Inevitably it seems like these conversations end up coming back to the issues from Chris Mooney and Matt Nisbet‘s Speaking Science workshop that SASS sponsored last summer.

There is huge discomfort for scientists in the fact that the way in which information is conveyed impacts how it is interpreted.  The idea is at odds with the scientific ideal of objective facts and communication, but nevertheless it is true.  A one liter glass plus 500 ml of water equals what?  The glass is half empty.  The glass is half full.  The glass is twice as big as necessary to hold that much water.  The same objective facts, different connotations.  Different implications.  Different frames.  And sometimes, the frame ends up being a more important determinant of the listener’s reaction than the information the speaker intended to convey.

  • Wal-Mart To Become Green Umpire – Wal-Mart arguably has more control over and insight into its supply chain than any other company on earth. The information they need in order to be able to force their suppliers to produce the goods as cheaply as humanly possible overlaps substantially with the information required to provide transparent information about the environmental impacts of those same products. Wal-Mart says they want to use this power for good… for telling, in condensed form, the sustainability back-story for their products. But will they tell the truth? Will it be transparent? Will it be verifiable? And even if it is… will their customers care? Might it change their customer base?
  • Howtoons – A series of comics which both tell stories, and inspire kids to build their own toys and tools. Wonderful hacker propaganda.
  • Where's the Real Bottleneck in Scientific Computing? – A story about a computer scientist talking to physicists who have hundreds of thousands of lines of code, and don't know what version control or unit testing is. Hmm. I guess I don't really know what unit testing is either.
  • Software Carpentry – A Python based tutorial for scientists and engineers who need to learn how to (actually) program. How could it have taken this long to appear?

On the Pareto frontier in salary-vacation space

Dear (Prospective Employer),

Thank you for your monetarily very generous offer of employment!  Honestly, it’s not obvious to me how I could spend $X a year, as I am currently living quite comfortably on about one Nth of that amount.  Actually, that’s not entirely true; I’m sure I could spend it all if I got a mortgage on a big house out in the suburbs, bought a fancy car with which to commute to work, ate out frequently, and had a few kids I planned to put through college.  However, I prefer to live simply in a small home, cook my own meals, bus or bike to work, and I may very well choose not to reproduce.  I also prefer, in my all too limited time on Earth, to experience the wilderness that still remains in the world, and the myriad human cultures, cuisines, and languages that have emerged in the last 50,000 years.  Those experiences will not come easily sitting in front of a computer in an office park, and they often cannot be had on weekends or whirlwind tours.  Thus, I am concerned about the following potential scenario with your offer of employment as it currently stands.

A Letter to David Bodansky

Hello Prof. Bodansky,

I’m a PhD student in geophysics, and I just finished reading your book, Nuclear Energy.  I appreciate the trouble you went to in the book to remain effectively neutral as to whether we ought to be pursuing the development of nuclear power.  While I can’t say that the book made me into a nuclear advocate, I am less opposed to it in principle now, and believe that it does represent a potential long term energy solution, albeit one with non-trivial caveats.  Then again, that seems to be the case with all of our options at this point.

Caltech PhD Students Collecting Food

Just pulled a week’s worth of food out of a Trader Joe’s dumpster.  Eggs, blueberries, apricots, chocolate cake, frozen ribs, chicken thighs, lettuce, bagels, breads of every description.  We kept a bunch of it.  Sorted the fruit into compost vs. smoothie quality, froze the latter.  Sent what we couldn’t eat to a homeless shelter with another volunteer.  I feel like the more I look at the margin of our society, the more I have to wonder, what the fuck are we doing?  How did we get to this place, to this way of being?  How can we think that this is okay?  One hundred gallons of water for every ounce of beef; ten fossil calories burned for every one we produce as food, and then a third of that food sent to the landfill, while people, only a couple of miles away, are hungry?  While whole neighborhoods in South Central LA have no grocery stores, only liquor stores and fast food junk?

Maybe more importantly at this point, where are we going with this?  It’s a long way down from here.

Nuclear Energy by David Bodansky

Nuclear Energy by David BodanskyI just finished David Bodansky’s 600+ page tome Nuclear Energy.  It’s almost a textbook, but not quite.  I don’t know who the intended audience is really.  Other than me.  Similar genre, broadly, as The High Cost of Free Parking.  A comprehensive overview of a technical topic, for those with a long attention span and no fear of numbers.  I decided to read the book because of the recent turn toward nuclear power that some environmentalists have taken.  There are many publics that react strongly, and negatively, to the idea, but I don’t trust public sentiment to be rational any more than I can manipulate it.  Bodansky did an admirable job of remaining neutral throughout the book, on a topic that almost universally devolves into something resembling a religious debate.  As a result of this reading, I’m much more positive (or rather, less negative) about nuclear energy than I was before.  I think that my position, which I hope can count as an informed one, now closely resembles that of Ralph Cavanagh, as articulated in this debate with Peter Schwartz hosted by the Long Now Foundation.

The main questions I had coming into the book were:

  1. Can nuclear energy be done responsibly?
  2. What would it take for it to scale up meaningfully?
  3. How would it compare in costs and risks to renewable energy sources, if it were done responsibly at scale?

The answers I came away with were that yes, it probably can be done responsibly, and at the scale necessary for it to be meaninful as a long term source of primary power globally.  However, if it were to scale up responsibly in the long term, it seems that the associated costs would likely end up being greater than for renewable energy sources.  So I guess I’m supportive of having the so-called “nuclear option” on the table, in competition with any other carbon free power source, with the significant caveat that the cost of the nuclear power being considered correspond to a responsible, long term, large scale deployment.  The scenario I foresee needing to be avoided is ending up with an unfair comparison, between short-term and/or irresponsible and/or non-scalable nuclear power, and renewables — especially renewables as priced before the solar power industry has obtained whatever economies of scale there are to be had in their niche.  One might be able to make a persuasive argument that we need to use nuclear power as a bridge between fossil fuels and renewables at scale, but I haven’t heard that argument made yet.
