"Verifier Approach" method maps scientific knowledge, proves ancient manuscript false

The Voynich Manuscript is an ancient hand-written text from the 16th century,written in an unknown langugage, and reminiscent of Leonardo da Vinci's notebooks. It contains fantastic drawings of plants and animals which appears to be purely imaginary, as well as sections with material resembling other areas of the natural sciences (although mostly fantastic/imaginary). Many attempts have been made through the centuries to decode the language contained in the volume, and many theories have been put forth regarding the contents, but so far none have been successful.
However, recently, Gordon Rugg , a psychologist teaching at the computer scientist department of the Keelee University near Manchester, England, took a different approach by using a method he had developed himself, called the Verifier Approach, and claims to have proved that the text is complete nonsense, and that there is no hidden message.
What is remarkable is that the method used is not a decryption mechanism in any sense, but what he did is that he actually analyzed the body of knowledge and all the work done so far relating to the analysis of the manuscript by various experts,building maps of the knowledge, looking at how they overlap, and identifying overlaps, discrepancies and empty areas where no work had ben done.

Rugg is also looking into applying the method into other areas, such as Alzheimer's disease, in order to improve the quality of and to speed along research in those areas.
