Metacognition collapses before perception
When the recursive meta-governance layer is disrupted, metacognitive accuracy (meta-d′) should degrade before basic perceptual sensitivity (d′) collapses. The system can still see — but it loses the capacity to know what it sees.
TMS or pharmacological disruption of dorsolateral and frontopolar prefrontal cortex during a perceptual decision task. Measure d′ (perceptual sensitivity) and meta-d′ (metacognitive accuracy) across increasing disruption levels.
Two divergent curves. Perceptual sensitivity (d′) holds nearly flat as disruption increases. Metacognitive accuracy (meta-d′) drops earlier and steeper. The dissociation is the signature.
If d′ and meta-d′ degrade at the same rate, or if meta-d′ remains intact while d′ collapses, the bounded-recursion hypothesis is in trouble. The claim is that meta-governance is a separable, prior layer — not just a downstream consequence of perception.
