Spontaneous order, also known as "self-organization", is the spontaneous emergence of order out of seeming chaos. It is a process found in physical, biological, and social networks, as well as economics, though the term "self-organization" is more often used for physical and biological processes, while "spontaneous order" is typically used to describe the emergence of various kinds of social orders from a combination of self-interested individuals who are not intentionally trying to create order through planning. The evolution of life on Earth, language, crystal structure, the Internet and a free market economy have all been proposed as examples of systems which evolved through spontaneous order. Naturalists often point to the inherent "watch-like" precision of uncultivated ecosystems and to the universe itself as ultimate examples of this phenomenon.
Spontaneous orders are to be distinguished from organizations. Spontaneous orders are distinguished by being scale-free networks, while organizations are hierarchical networks. Further, organizations can be and often are a part of spontaneous social orders, but the reverse is not true. Further, while organizations are created and controlled by humans, spontaneous orders are created, controlled, and controllable by no one. In economics and the social sciences, spontaneous order is defined as "the result of human actions, not of human design."
According to Murray Rothbard, Zhuangzi (369 BCE - 286 BCE) was the first to work out the idea of spontaneous order. The philosopher rejected the authoritarianism of Confucianism, writing that there "has been such a thing as letting mankind alone; there has never been such a thing as governing mankind [with success]." He articulated an early form of spontaneous order, asserting that "good order results spontaneously when things are let alone", a concept later "developed particularly by Proudhon in the nineteenth" century.
The thinkers of the Scottish Enlightenment were the first to seriously develop and inquire into the idea of the market as a spontaneous order. In 1767, the sociologist and historian Adam Ferguson described the phenomenon of spontaneous order in society as the "result of human action, but not the execution of any human design".
Many economic classical liberals, such as Hayek, have argued that market economies are a spontaneous order, "a more efficient allocation of societal resources than any design could achieve." They claim this spontaneous order (referred to as the extended order in Hayek's "The Fatal Conceit") is superior to any order a human mind can design due to the specifics of the information required. Centralized statistical data cannot convey this information because the statistics are created by abstracting away from the particulars of the situation.
In a market economy, price is the aggregation of information acquired when people are free to use their individual knowledge. Price then allows everyone dealing in a commodity or its substitutes to make decisions based on more information than he or she could personally acquire, information not statistically conveyable to a centralized authority. Interference from a central authority which affects price will have consequences they could not foresee because they do not know all of the particulars involved.
This is illustrated in the concept of the invisible hand proposed by Adam Smith in The Wealth of Nations. Thus in this view by acting on information with greater detail and accuracy than possible for any centralized authority, a more efficient economy is created to the benefit of a whole society.
Spontaneous order is what happens when you leave people alone—when entrepreneurs... see the desires of people... and then provide for them.
They respond to market signals, to prices. Prices tell them what's needed and how urgently and where. And it's infinitely better and more productive than relying on a handful of elites in some distant bureaucracy.
The concept of spontaneous order is closely related with modern game studies. As early as in the 1940s, historian Johan Huizinga wrote that "in myth and ritual the great instinctive forces of civilized life have their origin: law and order, commerce and profit, craft and art, poetry, wisdom and science. All are rooted in the primeval soil of play." Following on this in his book The Fatal Conceit, Hayek notably wrote that "a game is indeed a clear instance of a process wherein obedience to common rules by elements pursuing different and even conflicting purposes results in overall order."
Anarchists argue that the state is in fact an artificial creation of the ruling elite, and that true spontaneous order would arise if it was eliminated. Construed by some but not all as the ushering in of organization by anarchist law. In the anarchist view, such spontaneous order would involve the voluntary cooperation of individuals. According to the Oxford Dictionary of Sociology, "the work of many symbolic interactionists is largely compatible with the anarchist vision, since it harbours a view of society as spontaneous order." 
The concept of spontaneous order can also be seen in the works of the Russian Slavophile movements and in specific the works of Fyodor Dostoyevsky. The concept of an organic social manifestation as a concept in Russia expressed under the idea of sobornost. Sobornost was also used by Leo Tolstoy as an underpinning to the ideology of Christian anarchism. The concept was used to describe the uniting force behind the peasant or serf Obshchina in pre-Soviet Russia.
Perhaps the most famous theorist of social spontaneous orders is Friedrich Hayek. In addition to arguing the economy is a spontaneous order, which he termed a catallaxy, he argued that common law and the brain are also types of spontaneous orders. In "The Republic of Science," Michael Polanyi also argued that science is a spontaneous order, a theory further developed by Bill Butos and Thomas McQuade in a variety of papers. Gus DiZerega has argued that democracy is the spontaneous order form of government, David Emmanuel Andersson has argued that religion in places like the United States is a spontaneous order, and Troy Camplin argues that artistic and literary production are spontaneous orders. Paul Krugman too has contributed to spontaneous order theory in his book The Self-Organizing Economy, in which he explains that cities are self-organizing systems.
