I thought phrenology was still a science at the time of the German Reich, only made defunct later. Now I have my doubts.
Social darwinism was disproven in the 1900s and supply-side economics died in the 19th century so it’s not like pseudoscience does not spring up like weeds when rich people want to sponsor it.

The first thing that comes up on a websearch is books being chained to desks, to keep them from getting borrowed. I can’t imagine monks chained to their desks will be motivated to do good work, let alone fine art like illumination. Especially if they’re under a deadline, which would serve to propagate errors and misspellings.
