as summarized in :

" In 1988, Joseph Tainter wrote a chilling book called The Collapse of Complex Societies. Tainter looked at several societies that gradually arrived at a level of remarkable sophistication then suddenly collapsed: the Romans, the Lowlands Maya, the inhabitants of Chaco canyon. Every one of those groups had rich traditions, complex social structures, advanced technology, but despite their sophistication, they collapsed, impoverishing and scattering their citizens and leaving little but future archeological sites as evidence of previous greatness. Tainter asked himself whether there was some explanation common to these sudden dissolutions.

The answer he arrived at was that they hadn’t collapsed despite their cultural sophistication, they’d collapsed because of it. Subject to violent compression, Tainter’s story goes like this: a group of people, through a combination of social organization and environmental luck, finds itself with a surplus of resources. Managing this surplus makes society more complex—agriculture rewards mathematical skill, granaries require new forms of construction, and so on.

Early on, the marginal value of this complexity is positive—each additional bit of complexity more than pays for itself in improved output—but over time, the law of diminishing returns reduces the marginal value, until it disappears completely. At this point, any additional complexity is pure cost.

Tainter’s thesis is that when society’s elite members add one layer of bureaucracy or demand one tribute too many, they end up extracting all the value from their environment it is possible to extract and then some.

The ‘and them some’ is what causes the trouble. Complex societies collapse because, when some stress comes, those societies have become too inflexible to respond. In retrospect, this can seem mystifying. Why didn’t these societies just re-tool in less complex ways? The answer Tainter gives is the simplest one: When societies fail to respond to reduced circumstances through orderly downsizing, it isn’t because they don’t want to, it’s because they can’t.

In such systems, there is no way to make things a little bit simpler – the whole edifice becomes a huge, interlocking system not readily amenable to change. Tainter doesn’t regard the sudden decoherence of these societies as either a tragedy or a mistake—”[U]nder a situation of declining marginal returns collapse may be the most appropriate response”, to use his pitiless phrase. Furthermore, even when moderate adjustments could be made, they tend to be resisted, because any simplification discomfits elites.

When the value of complexity turns negative, a society plagued by an inability to react remains as complex as ever, right up to the moment where it becomes suddenly and dramatically simpler, which is to say right up to the moment of collapse. Collapse is simply the last remaining method of simplification. "


" One of the interesting questions about Tainter’s thesis is whether markets and democracy, the core mechanisms of the modern world, will let us avoid complexity-driven collapse, by keeping any one group of elites from seizing unbroken control. This is, as Tainter notes in his book, an open question. There is, however, one element of complex society into which neither markets nor democracy reach—bureaucracy.

Bureaucracies temporarily suspend the Second Law of Thermodynamics. In a bureaucracy, it’s easier to make a process more complex than to make it simpler, and easier to create a new burden than kill an old one.

In spring of 2007, the web video comedy In the Motherhood made the move to TV. In the Motherhood started online as a series of short videos, with viewers contributing funny stories from their own lives and voting on their favorites. This tactic generated good ideas at low cost as well as endearing the show to its viewers; the show’s tag line was “By Moms, For Moms, About Moms.”

The move to TV was an affirmation of this technique; when ABC launched the public forum for the new TV version, they told users their input “might just become inspiration for a story by the writers.”

Or it might not. Once the show moved to television, the Writers Guild of America got involved. They were OK with For and About Moms, but By Moms violated Guild rules. The producers tried to negotiate, to no avail, so the idea of audience engagement was canned (as was In the Motherhood itself some months later, after failing to engage viewers as the web version had).
