Agentless passive, hedging, zombie nouns. It’s the type of writing that’s meant to meet a word count.
Perhaps it is the contrast of "freely recommending" and "always should be considered carefully"?
Or taking a larger leap: the awkwardness of saying how hard (isolating) it is to do a PhD in an unfamiliar country, then saying that you enjoyed it, but others should consider it carefully?
I’ve read many academic papers in my life due to proofreading for friends & family, and a personal interest in (mainly) history.
It’s the deference and hedging disease. Even the most benign observations are covered in stuff like "this document from 1708 might look interesting, but it requires further study and I’d have to defer judgement to other figures in the field as I’m only studying documents from 1710-1715" or "This document from 1708, if looked carefully at from all sides, maybe, if this is not saying it too strongly, might look not uninteresting, but you have to always be careful in judging a document being interesting or not, and also I’m not in the position to judge the interestingness of anything for anyone, really, except for myself, at times".
That’s why pop science is so popular. It’s the confident kids in kindergarten.
I understand hedging, but not if it’s a total nothingburger like "You have to always be careful when X". No shit, Sherlock
