New paper models belief formation geometry under noisy observation

A new arXiv paper explores the geometric costs associated with belief formation in finite systems that operate with noisy observations. The research models the process as optimal transport in Wasserstein space, reweighted by Fisher information, to define a belief-cost geometry. Key findings include a 'wall' where inference rejects certainty, an 'honest family' of geometries equivalent to the Fisher family, and a 'rigidity' that points to hyperbolic geometries, with the Stam bound crowning the Gaussian as the most hyperbolic.
