Research Architecture: The Decision World Model (IVORI-V1) IVORI Lab's flagship research initiative is the **Decision World Model (IVORI-V1: A Neuro-Symbolic Foundation Social World Model for Decision Environments)**. Unlike generic generative LLMs that predict the most probable next token based on surface correlations, the Decision World Model is designed for causal inference and counterfactual simulation: 1. **Causal AI (Mechanism over Correlation)**: - Models the structural mechanisms that determine real-world outcomes in policy, legal, and operational systems. 2. **Counterfactual Simulation (Exploring Parallel Paths)**: - Simulates divergent decision paths in parallel, comparing predicted trade-offs, opportunity costs, and second-order consequences before committing to a decision read. 3. **Formal Decision Science**: - Built on expected-value maximization, Bayesian probability updating, and formal game-theoretic trade-off frameworks. 4. **Continuous Calibration**: - Continuously measures model confidence against unfolding real-world empirical outcomes to eliminate overconfidence and hallucination. --- ## 3.
