I.Q. is not measured by the number of stupid mistskes one has made and there is no such thing as a link between grammar and intelligence. Fact of the matter is, there is no wrong dialect and the dialect/grammar-intelligence link theory is but a myth :angry:. I.Q. is based on what one has learned thus far and one's ability to think critically. LF is too optimistic and ideal, Ducky is naive and innocent, Petrie is gullible, and Spike has not displayed an incredible amount of intelligence yet. This leaves Cera out. Sure, she may lose all sense when she panics, but she's also the wittiest and most realistic.
