[Poll for Mark Knowles] Explanation for Voynich text?

[tavie]

I think the answer lies in Nabalator's point about Option 2 being too wide.  The problem for your polls is that people read the options differently.  

Option 1 hasn't been chosen because most - if not all - of the theories you cite would see themselves as cyphers, mostly simple substitution theories.  If the language is usually written in a different script, and the scribes used Voynichese instead, that makes Voynichese a cypher. 

So if you had split simple substitution from the general cypher option, you would get somewhat more representative results.
