Our new paper in Physics of Life Reviews proposes that cognitive control optimizes the precision of beliefs in active inference, balancing deliberation and habits. A hierarchical model shows how a meta-cognitive level controls this.

These findings are crucial for developing targeted dietary interventions to support the health and quality of life of older adults.
