Somatic-marker hypothesis
Antonio Damasio, 1994
Damasio's patients could reason flawlessly and still wreck their lives, because the part of them that *felt* the difference between a good and a bad option had gone quiet. From this he argued the opposite of the old story: feeling is not the enemy of good judgment but an input to it. The body tags our options with value, and that tag — the somatic marker — is doing real cognitive work.
Working definition
Emotion-linked bodily signals ('somatic markers') bias choice toward advantageous options; reason without feeling is impaired, not purer.
Where Vela uses this
The somatic-marker hypothesis grounds Vela's attention to the body in emotion and in writing — the felt sense that arrives before the reasoned account and shapes it. It sits on the body-first side of the field's central divide, alongside basic emotions theory and polyvagal theory, in productive tension with the constructionist account. Vela uses it to take bodily knowing seriously without treating the gut as infallible.
Origin & lineage
Damasio (*Descartes' Error*, 1994; the Iowa Gambling Task with Bechara et al.) → wide uptake in affective neuroscience and decision research → critiques of the gambling-task evidence and the marker's causal role.

Honest framing
The strongest versions of the hypothesis, and the gambling-task findings behind them, have been seriously questioned. Vela holds the core insight — feeling informs reason — while noting the mechanism is less settled than its popular telling suggests.
