==Other fields== The term has come to be used in other fields, for example: ===Risk=== {{Main|Risk homeostasis}} An [[actuary]] may refer to ''risk homeostasis'', where (for example) people who have anti-lock brakes have no better safety record than those without anti-lock brakes, because the former unconsciously compensate for the safer vehicle via less-safe driving habits. Previous to the innovation of anti-lock brakes, certain maneuvers involved minor skids, evoking fear and avoidance: Now the anti-lock system moves the boundary for such feedback, and behavior patterns expand into the no-longer punitive area. It has also been suggested that ecological crises are an instance of risk homeostasis in which a particular behavior continues until proven dangerous or dramatic consequences actually occur.<ref

of a population or an individual to stay at a certain level of [[stress (biology)|stress]], often generating artificial stresses if the "natural" level of stress is not enough.<ref>{{Cite

inline|date=February 2020}} [[Jean-François Lyotard]], a postmodern theorist, has applied this term to societal 'power centers' that he describes in ''[[The Postmodern Condition]]'', as being 'governed by a principle of homeostasis,' for example, the scientific hierarchy, which will sometimes ignore a radical new discovery for years because it destabilizes previously accepted norms. ===Technology=== Familiar technological homeostatic mechanisms include: * A [[thermostat]] operates by switching heaters or air-conditioners on and off in response to the output of a temperature sensor. * [[Cruise control]] adjusts a car's throttle in response to changes in speed.<ref name="CarLife1965">{{cite journal |url=https://books.google.com/books?id=zO46AAAAMAAJ |page=46 |title=1966
