What happened
The Complex Brain Hypothesis starts from a puzzle in the Entropic Brain Hypothesis. Psychedelic high-content states can show elevated neural entropy, but some meditation-linked minimal phenomenal experiences - states with wakefulness and little or no content - may show elevated entropy too. If both "too much content" and "almost no content" raise entropy, entropy alone cannot be the index we want.
The authors propose complexity as the better lens: not just how noisy brain activity is, but how the brain resolves uncertainty at different grains of inference. That shifts the conversation from a single dial to a richer model of conscious content.
For philosophy of mind, this is the useful move: sharpen the measurement before arguing about the metaphysics.
