One must be careful not to confuse specialized knowledge with high intelligence. It’s easy to be impressed with a dense document, detailed with specialized language and concepts (particularly if they are mathematical). One might read this document and assume that the writer is highly intelligent but this is not always the case. There is a substantial difference between one with specialized knowledge and one with high intelligence. There is an even greater difference between one with specialized knowledge and one with creative intelligence. One must learn to detect the distinctions.
