Making Sense of Uncertainty: Designing Experiences for Adaptive Inference

Anna L. Pereira — Active Inference LLC, 2025

A design-led framework for translating active inference and the free energy principle into practical tools—using a four-quadrant model spanning mind, body, and environment to help people engage adaptively with uncertainty.

Toward a More Legible Humanity: Communication, Inference, and the Design of Human Coordination Systems

Anna Pereira PhD MS & Guido van Nispen — June 2026

Reframes communication as a mechanism for aligning internal models between people, arguing that better communication makes shared systems more robust and less prone to breakdown.
