For example, the emerging dune may become either slightly larger or smaller than it was when it encountered the
second sandpile.
Haas, Creamer, and Shady all agree that this settlement — now a cluster of
sandpiles overlooking a salt marsh, half a mile from the Pacific — may have equaled Aspero in preceramic times.
Scientists began
examining sandpiles and discovered that each tiny grain of sand added to the pile increased the overall risk of avalanche but which grain of sand would make the difference and when the big avalanches would occur remained unknown and unknowable.
Turning to
the sandpile as the metaphor for markets, these innovations represent the «long fingers of instability».
In other words, the higher
the sandpile, the more likely a crash.
The sandpile might grow increasingly shaky and an avalanche become increasingly likely but it can get a lot higher before that last tiny grain of sand finally makes a difference.
How high is
the sandpile now?
Examples which are often quoted to illustrate this are
sandpiles, avalanches, forest fires, etc, and an essential ingredient for such phenomena seem to be interaction - dominated thesholds.
an Internet argument tactic involving a reprinting of an article or blog post, interlarded with rebuttals and refutations, often intended to show the original is
a sandpile of flawed facts, unfounded assertions, and logical fallacies.
