Folks, I apologize if I missed this in an earlier part of the thread... these discussions are so elaborate and rich that I simply find I cannot keep up with them all front to back.
However... this divergence of discussing bicyclist pelotons which is segueing into what feels like a discussion of seeking solutions to what is known as the "Tragedy of the Commons" has gotten my attention. > The canonical example is of a resource that begins with having no limit for > a small community of users with various cooperative habits for exploiting > it.

The bicycle peleton seems to arise fairly directly from "reciprocal altruism". While there is some cost to the riders at the head of a peloton in terms of simple distraction and risk of interference, in general the only cost they bear is relative to the others who gain an advantage from an emergent common resource, the air pocket behind them which is unexploited otherwise. "reciprocal altruism" is an obvious response, each member of the peleton being motivated to contribute to the group as a "windbreaker" in exchange for not being ejected or ditched from the peleton. As the end of the race nears, the motivation to "defect" increases and only those with a shared fate (members of the same team) are likely to maintain pelotons right up to the last minute. Phil makes good points about global optimization under local awareness. As our actions begin to have longer range consequences and we begin to exploit a larger commons (global, including earth orbit, Lagrange points, and the lunar surface soon enough) our awareness of the state of said commons must be expanded equally. This also is problematic, as our awareness must be mediated both technologically and socially (we must use telescopes, remote sensors, etc. and depend on others to share their observations and judgements about the condition of the commons). When these other devices (mechanical and social) are insinuated between our perceptual system and the commons in question, we are at risk of them being miscalibrated and of our innate perceptions not being tuned to them. We simply may not understand the implications of what our instruments are telling us in the first case and in the second case, we may not trust the agenda of the social constructs between us and what we are observing (see the long-running arguement over whether climate change is real or not). - Steve ============================================================ FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College lectures, archives, unsubscribe, maps at http://www.friam.org
