He's probably referring to situations where a person loses their ability to access their intuition in making decisions, even very simple ones like what to eat for lunch. The result is gridlock in the brain. The patient cannot, literally, decide if next Wednesday at 3pm is an okay time to have their next appointment with a therapist. The takeaway is that conscious "rationality" alone in humans is clearly insufficient for them to make most decisions. Instead, they act, for the most part, on intuition and feelings, guided (we hope) by rational feedback to the correct for the deficiencies in those two "dominant" modes of thinking and decision making.
