Title: Self-organization in Science and Society: an introduction
1Self-organization in Science and Society an
introduction
2What is STS?
- Usually we think about science having impact on
society eg cars and sex in 1950s - But society has an impact on science eg
- the global warming debate was largely the
creation of oil company funding (cf.
http//www.ucsusa.org/publications/catalyst/exxon-
exposed.html - The impact can also be good (as we will soon see)
- Nature is also in this dielectic so
3What is STS?
4 What isnt self-organization? Top-down someone
in charge organizes stuff Militarygeneral,

What is self- organization? Bottom-up the stuff
organizes itself Biological evolution Flocks
and swarms bees, birds, whales, wolves,
etc. Crowdsourcing WWW, Wikipedia, Open
Source, etc. Subsumption architecture
(robotics), Molecular self-assembly (nano),
5 Why do dictatorships love linear order?
6 Why do democracies accept disorder?
7What about in-between?
top-down
bottom-up
- This spectrum exists for many other systems eg
human nervous system combines - centralization (brain vs peripheral ns) with
self-organization (neural nets) - Note that thinking about social structures can
help us think about natural structures
8How disorganized can self-organization be?
Salt crystal forms from evaporating water.
Completely ordered. Trivial case.
- Toss a handful of particles in the air
self-organized but without order. Trival case
- Sand waves from wind action a quasi-ordered
emergent pattern. - Significant case.
Self-organization tends to be a more salient
description when describing systems between total
order and total disorder
9 Top-down tools Bottom-up tools
Tool Linear Non-linear
Spatial analysis Euclidean geometry Fractal geometry
Dynamics Newtonian mechanics Chaos theory
Collective behavior Statistics Complexity theory
10 Top-down tools Bottom-up tools
Tool Linear Non-linear
Communication Shannon-weaver (classical information theory) Network theory (scale-free topologies)
Optimization Operations research (linear programming etc.) Fitness landscape, genetic algorithms
Artificial Intelligence GOFAI (Expert systems, high level symbol manipulation) Neuromimetics, subsumption architecture, etc.
11Most theories of self-organizing systems fall
under the rubric of Complexity Theory. But
what is the distinction between Complexity Theory
and Theorizing Things that are Complicated? Which
is more complex?
- A gas made of 15 million molecules randomly
crashing about? - OR
- A school made of 15 fish gracefully swirling
though water?
12Emergence is global behavior of a system
resulting from collective interactions of loosely
coupled components.Temperature an emergent
property of swarms of molecules. But temperature
is based on the average velocity of molecules
(E3kT/2). Linear relation, you can use
statistics. Flocking an emergent property of
swarms of animals (birds, ants, fish, etc.).
Flock movements are not well characterized by
averages or statistics. They are nonlinear,
adaptive, anticipative, have memory. They have
synergy the whole is greater than the
parts. Complicated just means there is so much
going on we cant keep track of it Complexity
synergistic emergent behavior often adaptive
(hence complex adaptive systems).
13But we can go even deeper
- At the heart of self-organization lies recursion
- Recursion is also at the heart of many social
ideals democracy, freedom, egalitarianism. - Therefore it should be no surprise that some of
the founders of self-organization in science were
also activists for self-organization in society.
