There were some suggestive words from the blog Faktoider (faktoider.blogspot.com) about this case (Swedish):
To provide a basic summary of the above, in the blog the author notes that Cheshire recently defended a PhD (in Biology, a subject not related to language) with the title "an adaptive theory for human belief systems" which raises thoughts that his drills with the Voynich manuscript in actuality is an experiment.
Who knows?
Quote:Det kan tilläggas att Gerard Cheshire nyligen doktorerat på Bristols universitet. Men inte inom något språkrelaterat, utan inom biologi. Hans avhandling handlar om "an adaptive theory for human belief systems" vilket väcker funderingar på om hans övningar med MS408 i själva verket är ett experiment.
