Precision adverbs
An examiner of a scientific thesis wants a ban on words indicating a probability not entirely certain:
"Page N: 'Although the correspondence between the XXX and YYY frameworks is not clear, it is likely that ...' Hmmm. Scientific sentences containing adverbs such as 'likely' (or 'very', 'hardly', 'quite', 'almost', 'nearly' ...) are highly likely to be not very scientific. Either write something concrete about the relationship between the XXX and the YYY, or don't write anything at all."
I expect the same precision is required in a humanities thesis.
