Futuredependent

Futuredependent is a term used in philosophy and physics to describe situations in which present states, decisions, or events are influenced by, or conditioned on, information about the future. It does not denote a single established theory, but a family of ideas about how future conditions can play a role in determining current phenomena.

In physics, future dependence is associated with retrocausal or time-symmetric approaches to quantum mechanics. In these approaches, boundary conditions are specified at both the start and end of a process, and some observable outcomes are interpreted as being contingent on a future boundary. Proponents contend that such models can account for quantum correlations without requiring faster-than-light signaling and may restore a more symmetric treatment of time. Critics argue that invoking future boundary conditions challenges standard notions of causality, can introduce conceptual paradoxes, and often lacks unique empirical predictions.

In other domains, the phrase may appear in discussions of decision theory or economics to denote that choices or policies are contingent on expected future states or rewards, sometimes framed as future-dependent preferences or strategies. However this usage is informal and less standardized than its physics-oriented use.

Related concepts include retrocausality, time-symmetric quantum mechanics, and boundary-condition formulations of physical theories. Debates over future dependence center on questions of causality, realism, and testability, with ongoing work in philosophy of science and quantum foundations exploring whether future-dependent models offer explanatory or predictive advantages.
