Trident G: Free Energy & Brain Criticality Based Theory of Intelligence & Resilience

This paper presents the Trident G Theory, a novel theoretical framework for understanding human intelligence. The theory takes a systems-level approach. It draws on principles of brain criticality, the Free Energy Principle, self-organisation and allostasis to explain how the brain achieves an optimal balance for information processing and adaptive behaviour.The brain's near-criticality allows for flexible, efficient information processing and enables rapid adaptation to changing environmental demands. Key concepts include metastability, where multiple cognitive states can co-exist, and the Free Energy Principle, which frames the brain's drive to minimise uncertainty and prediction error.The Trident G theory uniquely defines intelligence across two axes: processing/inference (vertical) and free energy (horizontal). The vertical axis represents the metastable balance between 'top-down' executive control and 'bottom-up' creative exploration. The horizontal axis reflects cognitive resilience across a spectrum of free energy and arousal, governed by dopaminergic tone. The brain's allostatic capacity to maintain criticality along both axes is hypothesized to define a dynamic range of general adaptive intelligence (G).The theory offers a novel perspective on the neural basis of intelligence, potentially informing the understanding of cognitive disorders and guiding the development of interventions aimed at enhancing cognitive function and resilience across the lifespan.
