Computational models for systems you can't fully observe. Behavioral Pathways is a research organization building tools for psychological and behavioral simulation. We develop inference engines grounded in established theory and empirical research, designed for researchers, AI developers, and simulation engineers who need rigorous behavioral modeling.
Human behavior is like weather: pattern analysis at scale, physics at the micro level. But behavioral systems face fundamental limits - the state is unknowable, even if known it is intractable, and there is no deterministic ground truth to converge on.
Our Rust library treats psychology as a queryable computation. You provide entities, events, and timestamps. We compute state at any point in time. Every psychological dimension - mood, personality, trust, needs - uses the same StateValue abstraction: stable tendency plus temporary deviations that decay over time.

Walk through complete simulation examples showing how personality traits influence trust decisions and how mood changes after life events.
How personality shapes willingness to trust others, with code showing entity creation, relationship modeling, and trust computation.
How mood declines after negative events and recovers over time through the decay mechanism.
How severe life events shift baseline traits permanently, with base shifts and settling curves.
How TB, PB, and AC converge into risk alerts using the ITS monitoring pipeline.
How single events affect multiple ITS pathways (e.g., JobLoss → TB + PB).
