Decision Making
Every decision is embodied before it is conscious.
Classical models of decision-making treated the process as a calculation performed in prefrontal cortex — a weighing of options against explicit criteria. Contemporary neuroscience has enriched this picture substantially. Every decision is embedded in bodily state; every option is felt before it is evaluated; the "gut feeling" that arrives just before the conclusion is not superstition but signal.
§ 1
The somatic marker hypothesis
Antonio Damasio’s somatic marker hypothesis proposed that emotional-bodily responses to potential outcomes guide decision-making, biasing us toward or away from options before deliberate reasoning completes. Patients with damage to ventromedial prefrontal cortex — a region that integrates body signal with valuation — make measurably poorer decisions in complex uncertain environments, despite intact reasoning.54

Interoception in choice
§ 3
Autonomic priors on decision
The autonomic state a person is in — coherent, activated, shut down — biases their decisions in reliable ways. A dysregulated nervous system reads its options through a threat lens; a regulated one reads the same options through curiosity.26,19
This is one of the strongest arguments for regulation as a precondition for good judgment, not merely for comfort.
§ 4
The NSI reading
Nervous System Intelligence adds a step to decision-making: notice the felt state of the body before the choice is made. What the body signals is not the answer, but it is data — and it is data that pre-cognitive systems have already integrated.
