What was John F. Kennedy Jr.'s IQ?

John Kennedy jr. had a University degree, so his IQ must have been in the region of about 120. How he used that intelligence is another matter. He mostly lived the life of a socialite and was a not very succesful magazine editor. The plane crash that killed him also isn't proof of his intelligent judgement: he took off as the pilot of the plane in conditions he was not really qualified for and refused the offer of an experienced pilot to come along on the flight.
