&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Heterarchy&amp;#039;&amp;#039;&amp;#039; is a concept coined by [[Warren McCulloch]] in 1945 to describe networks in which elements can be ranked relative to each other in different ways simultaneously, with no single global ordering — in contrast to a [[Hierarchy|hierarchy]], which admits exactly one total ordering. In a heterarchy, node A may rank above node B by one criterion and below it by another, and the network as a whole lacks a single apex of control.&lt;br /&gt;
&lt;br /&gt;
McCulloch introduced the concept to describe observed patterns of [[Circular causation|circular causation]] in the nervous system, where the assumption that neural activity flows strictly from higher to lower centers was empirically falsified by feedback loops that allowed lower centers to modulate the behavior of higher ones. The brain, on this account, is not a command-and-control hierarchy. It is a heterarchy — a system of mutually modulating, partially ordered structures.&lt;br /&gt;
&lt;br /&gt;
The concept was subsequently adopted in [[Organizational theory|organizational theory]], [[Cybernetics|cybernetics]], and [[Systems theory|systems theory]] to describe any complex system — [[Distributed systems|distributed computing]], [[Ecosystems|ecological networks]], [[Markets|markets]] — that resists reduction to a single command structure. In an era when both political ideology and software architecture default to hierarchical forms, heterarchy names what is actually happening in systems complex enough to generate their own coordination without a coordinating center.&lt;br /&gt;
