predij

Predij is a term used in speculative fiction and design discourse to describe a predictive decision framework that combines probabilistic forecasting with action selection in dynamic environments. It is treated as a conceptual tool rather than a concrete technology.

The term is often described as a portmanteau of "predict" and a fictional suffix "-dij," intended to evoke ahead-of-time reasoning. It has no standardized formal definition outside theoretical discussions.

Predij models future states as a set of discrete scenarios with associated probabilities; agents compute expected utilities to choose actions. It emphasizes uncertainty management, explainability, and compatibility with simulations, narrative design, and AI planning.

In world-building and game design, predij informs branching narratives and adaptive systems. In scholarly speculation, it provides a framework for comparing predictive strategies and agent architectures. Some designers use predij as an umbrella term for pre-decision forecasting mechanisms.

Variants such as Predij-Local and Predij-Dimensional denote different scopes of forecasting; fictional case studies illustrate predij forecasting weather, social dynamics, or battlefield movements within a story or simulation.
