(economics) A paradox of economics, stating that an increase in autonomous saving leads to a decrease in aggregate demand and thus a decrease in gross output which will in turn lower total saving: narrowly speaking, total saving may fall because of individuals' attempts to increase their saving, and, broadly speaking, increase in saving may be harmful to an economy.

plural of paradox of thrift

plural of twins paradox

plural of clock paradox

The objection that it should not be possible to deduce an irreversible process from time-symmetric dynamics.

plural of Abilene paradox

The situation where a group of people collectively decide on a course of action that goes against the preferences of many or all of the individuals in the group, because the individuals choose to side with what they believe is the majority preference.

(physics) A physical paradox that arises when considering the buoyant force exerted on a relativistic bullet (or in a submarine) immersed in a fluid subject to an ambient gravitational field. If a bullet has neutral buoyancy at rest in a perfect fluid and is then launched at relativistic speed, observers at rest within the fluid would conclude that the bullet should sink, since its density will increase due to the length contraction effect. On the other hand, in the bullet's proper frame it is the moving fluid that becomes denser and hence the bullet would float.

(economics) The observation that the rate of interest and the general level of prices are positively correlated.

(physics) Synonym of Supplee's paradox
