The information geometry of choice

A probabilistic model of spatial decision making, examining how geometry and uncertainty shape compromise, hedging, and commitment between alternative targets. The visualizations relate movement and changing beliefs to the spatial structure of information.

Each path starts with the selected preferences. Random fluctuations can tip the decision toward a target.

About the model

Part of ongoing research on decision making under uncertainty. The simulations examine compromise between alternatives, hedging through movement that keeps several options open, and commitment to a single target. These patterns can be compared across target configurations and parameter settings. Background fields represent posterior belief, entropy, or directional sensitivity.
