Factual error: Henry Deacon says people only use 10% of their brain at any one time. That's complete garbage - at times we may use quite a small part of our brains, other times the whole brain lights up with activity.

Given the intelligence of Eureka's residents, Henry (and indeed others in the room) would know this.
