Why the gut brain is right™

The human edge, seated in the body. There's a real second brain in your gut (the enteric nervous system; 500 million-plus neurons, more than the spinal cord; wired to the head by the vagus nerve in a two-way gut-brain axis; verified, cited science). So the gut feeling isn't soft; it has a physical seat, and it usually knows first. The turn: the machine has a kind of mind but no gut; it can describe fear, it can't feel the drop; and that missing organ is the whole point. A score is a judgment, and human judgment is never only in the head; it's felt. The capacity to be affected; to be sickened, moved, weighed down by a call in the body; is the qualification to make the call (a verdict that can't be hurt is a weather report). Doubt shows up as a feeling first, the hesitation before the words; that's the devil's advocate you carry in your body, the one the machine will never have. (Honest footing: the science is verified and sourced on the page; “the gut is right” is his labeled framing about where judgment is seated, NOT a claim that instinct never misses; the gut can mislead too. Feel the signal; then test it against the record. Not medical advice.) Kin: why the gut brain is right (the page), only humans score, the clerk and the jury, the biological pulse, the defense of the devil's advocate, the Tell (confidence without doubt). (His coin; machine's read, refine to his.)
