==== Friedrich Hayek and Catallactics ==== Economist and philosopher Friedrich Hayek (1899 – 1992) is another key figure in the Austrian School of Economics who is notable for his comments on unintended consequences. In "The Use of Knowledge in Society" (1945) Hayek argues that a centrally planned economy cannot reach the level of efficiency of the free market economy because the necessary (and pertinent) information for decision-making is not concentrated but dispersed among a vast number of agents. Then, for Hayek, the price system in the free market allows the members of a society to anonymously coordinate for the most efficient use of resources, for example, in a situation of scarcity of a raw material, the price increase would coordinate the actions of an uncountable amount of individuals "in the right direction". The development of this system of interactions would allow the progress of society, and individuals would carry it out without knowing all its implications, given the dispersion (or lack of concentration) of information. The implication of this is that the social order (which derives from social progress, which in turn derives from the economy), would be result of a spontaneous cooperation and also an unintended consequence, being born from a process of which no individual or group had all the information available or could know all possible outcomes. In the Austrian school, this process of social adjustment that generates a social order in an unintendedly way is known as catallactics. For Hayek and the Austrian School, the number of individuals involved in the process of creating a social order defines the type of unintended consequence:
If the process involves interactions and decision making of as many individuals (members of a society) as possible (thus gathering the greatest amount of knowledge dispersed among them), this process of "catallaxy" will lead to unexpected benefits (a social order and progress) On the other hand, attempts by individuals or limited groups (who lack all the necessary information) to achieve a new or better order, will end in unexpected drawbacks.
=== Robert K. Merton === Sociologist Robert K. Merton popularised this concept in the twentieth century. In "The Unanticipated Consequences of Purposive Social Action" (1936), Merton tried to apply a systematic analysis to the problem of unintended consequences of deliberate acts intended to cause social change. He emphasized that his term purposive action, "[was exclusively] concerned with 'conduct' as distinct from 'behavior.' That is, with action that involves motives and consequently a choice between various alternatives". Merton's usage included deviations from what Max Weber defined as rational social action: instrumentally rational and value rational. Merton also stated that "no blanket statement categorically affirming or denying the practical feasibility of all social planning is warranted."
=== Everyday usage === More recently, the law of unintended consequences has come to be used as an adage or idiomatic warning that an intervention in a complex system tends to create unanticipated and often undesirable outcomes. Akin to Murphy's law, it is commonly used as a wry or humorous warning against the hubristic belief that humans can fully control the world around them, not to presuppose a belief in predestination or a lack or a disbelief in that of free will.
== Causes == Possible causes of unintended consequences include the world's inherent complexity (parts of a system responding to changes in the environment), perverse incentives, human stupidity, self-deception, failure to account for human nature, or other cognitive or emotional biases. As a sub-component of complexity (in the scientific sense), the chaotic nature of the universe—and especially its quality of having small, apparently insignificant changes with far-reaching effects (e.g., the butterfly effect)—applies. In 1936, Robert K. Merton listed five possible causes of unanticipated consequences:
Ignorance, making it impossible to anticipate everything, thereby leading to incomplete analysis. Errors in analysis of the problem or following habits that worked in the past but may not apply to the current situation. Immediate interests overriding long-term interests. Basic values which may require or prohibit certain actions even if the long-term result might be unfavourable (these long-term consequences may eventually cause changes in basic values). Self-defeating prophecy, or, the fear of some consequence which drives people to find solutions before the problem occurs, thus the non-occurrence of the problem is not anticipated. In addition to Merton's causes, psychologist Stuart Vyse has noted that groupthink, described by Irving Janis, has been blamed for some decisions that result in unintended consequences.

=== Unexpected benefits === The creation of "no-man's lands" during the Cold War, in places such as the border between Eastern and Western Europe, and the Korean Demilitarized Zone, has led to large natural habitats.
The sinking of ships in shallow waters during wartime has created many artificial coral reefs, which can be scientifically valuable and have become an attraction for recreational divers. This led to the deliberate sinking of retired ships for the purpose of replacing coral reefs lost to global warming and other factors. In medicine, most drugs have unintended consequences ('side effects') associated with their use. However, some are beneficial. For instance, aspirin, a pain reliever, is also an anticoagulant that can help prevent heart attacks and reduce the severity and damage from thrombotic strokes. Beneficial side effects have also lead to off-label use –prescription or use of a drug for an unlicensed purpose. Famously, the drug Viagra was developed to lower blood pressure, with its use for treating erectile dysfunction being discovered as a side effect in clinical trials. In papal conclave journalism, Cardinal Fridolin Ambongo Besungu of Kinshasa in the Democratic Republic of Congo, the elected leader of all the bishops of Africa (including Madagascar), by early 2024 had come to be regarded as papabile for his adroit handling of the issue of blessing same sex unions, to which he is staunchly opposed.
