Among comments made concerning the specific testing of President GW Bush, his low ratings were due to his apparent difficulty to command the English language in public statements, his limited use of vocabulary (6,500 words for Bush versus an average of 11,000 words for other presidents), his lack of scholarly achievements other than a basic MBA, and an absence of any body of work which could be studied on an intellectual basis. The complete report documents the methods and procedures used to arrive at these ratings, including depth of sentence structure and voice stress confidence analysis. |
