This video reminded me of Voynich "I'VE SOLVED IT!" manuscript, cases so much

[Koen G]

To use the terminology of the Dunning-Kruger graph, we are often dealing with people who have set up camp at the "peak of Mount Stupid". Our duty, as peers, is to get them to descend into the Valley of Despair; an unpleasant phase we have to go through before we can start building actual expertise. It is no wonder this usually fails, and theorists prefer to stay put on the Peak instead.

The experience Neil deGrasse Tyson describes in this video reminds me a lot of what I went through with a certain well-known theorist. I took a large part of my day to point out to him the problems with his theory, starting with fundamental concepts of linguistics. All to no avail. 

As mentioned in another thread, many Voynich solutions have an inbuilt mechanism that makes reduplication impossible to attempt. So it's not only that repeating the process leads to different results. It's that the process is inherently unrepeatable because it requires some oracle-like interpretation from the lofty peaks of Mount Stupid. A black box mere mortals cannot access.
