The following article hits the motherlode when it comes to our past
discussions of Ur patterns, iteration, and fracticality. Ur patterns are those that
show up on multiple levels of emergence, patterns that make anthropomorphism
a reasonable way of doing science, patterns that explain why a metaphor can
capture in its word-picture the underlying structure of a whirlwind, a
brain-spin, or a culture-shift.
Here’s how a pattern in the molecules of magnets repeats itself in the mass
moodswings of human beings. Howard

Buchanan FADS, fashions and dramatic shifts in public opinion all appear to
follow a physical law: one of the laws of magnetism. Quentin Michard of the
School of Industrial Physics and Chemistry in Paris and Jean-Philippe Bouchaud
of the Atomic Energy Commission in Saclay, France, were trying to explain
three social trends: plummeting European birth rates in the late 20th century,
the rapid adoption of cellphones in Europe in the 1990s and the way people
clapping at a concert suddenly stop doing so. In each case, they theorised,
individuals not only have their own preferences, but also tend to imitate
others. "Imitation is deeply rooted in biology as a survival strategy," says
Bouchaud. In particular, people frequently copy others who they think know
something they don't. To model the consequences of imitation, the researchers
turned to the physics of magnets. An applied magnetic field will coerce the spins
of atoms in a magnetic material to point in a certain direction. And often
an atom's spin direction pushes the spins of neighbouring atoms to point in a
similar direction. And even if an applied field changes direction slowly, the
spins sometimes flip all together and quite abruptly. The physicists
modified the model such that the atoms represented people and the direction of the
spin indicated a person's behaviour, and used it to predict shifts in public
opinion. In the case of cellphones, for example, it is clear that as more
people realised how useful they were, and as their price dropped, more people
would buy them. But how quickly the trend took off depended on how strongly
people influenced each other. The magnetic model predicts that when people
have a strong tendency to imitate others, shifts in behaviour will be faster,
and there may even be discontinuous jumps, with many people adopting cellphones
virtually overnight. More specifically, the model suggests that the rate
of opinion change accelerates in a mathematically predictable way, with ever
greater numbers of people changing their minds as the population nears the
point of maximum change. Michard and Bouchaud checked this prediction against
their model and found that the trends in birth rates and cellphone usage in
European nations conformed quite accurately to this pattern. The same was true
of the rate at which clapping died away in concerts. Close this window
