 He didn't want to stay out the media; he wanted Free media; and he got it.

The Carnegie Mellon analysis is irrelevant to his results.  The US Army had to 'dumb down' its training to the 8th grade reading level when we went All Volunteer army in the 1980's.  And IQs have been steadily dropping since.
