Patience (or ) is the state of endurance under difficult circumstances, which can mean persevering in the face of delay or provocation without acting on negative annoyance/anger; or exhibiting forbearance when under strain, especially when faced with longer-term difficulties. Patience is the level of endurance one can have before negativity. It is also used to refer to the character trait of being steadfast. Antonyms include and .
In psychology and in cognitive neuroscience, patience is studied as a decision-making problem, involving the choice of either a small reward in the short-term, or a more valuable reward in the long-term. When given a choice, all animals, humans included, are inclined to favour short-term rewards over long-term rewards. This is despite the often greater benefits associated with long-term rewards.
In 2005 a study involving common marmosets and cottontop tamarins, animals of both species faced a self-control paradigm in which individuals chose between taking an immediate small reward and waiting a variable amount of time for a large reward. Under these conditions, marmosets waited significantly longer for food than tamarins. This difference cannot be explained by life history, social behaviour or brain size. It can, however, be explained by feeding ecology: marmosets rely on gum, a food product acquired by waiting for exudate to flow from trees, whereas tamarins feed on insects, a food product requiring impulsive action. Foraging ecology, therefore, may provide a selective pressure for the evolution of self-control.
Patience of human users in the online world has been the subject of much recent scientific research. In a 2012 study involving tens of millions of users who watched videos on the Internet, Krishnan and Sitaraman show that online users lose patience in as little as two seconds while waiting for their chosen video to start playing. The study also shows that users who are connected to the Internet at faster speeds are less patient than their counterparts connected at slower speeds, demonstrating a link between the human expectation of speed and human patience. These and other scientific studies of patience have led many social commentators to conclude that the rapid pace of technology is rewiring humans to be less and less patient.
