Towards a theory of biological intelligence

There exists an underexplored correlation between intelligence and perceptual discrimination. Perceptual discrimination can be understood through the concept of precision in predictive processing. Precision governs the weighting of sensory inputs and prediction errors, shaping how effectively an individual can extract meaningful information from their environment. We here propose a link between intelligence and precision, arguing that the ability to dynamically regulate precision is a key determinant of intelligent behavior. This perspective bridges individual cognitive differences with broader theoretical models of human brain functioning, offering a more comprehensive understanding of how intelligence manifests in biological systems.
