I'm a PhD student in sociology. I'm approaching graduation and facing a lot of pressure to publish. Specifically, one of my manuscripts is already on its fourth revision. However, I've noticed that my supervisors keep raising "new issues" for me to revise every time they review it.
I understand that it's normal to continuously improve a manuscript, but the "new issues" they keep pointing out are things that should have been raised during earlier reviews. These are not just aesthetic issues: for example, one advisor asked me to change measurement scales, which would require changing all my data and possibly collecting new data. If such a change were really necessary, it should have been brought up years ago. In this instance, I was able to convince him that my original choice was appropriate, but this pattern has happened countless times over the past four years.
It makes me suspect that when the submission deadline was still far away, these two supervisors didn’t carefully read my manuscript, or only selectively read the parts they were interested in (just to "get the task done"). This behavior is extremely frustrating for me.
In theory, the more you revise a manuscript, the fewer problems should remain. But every time I seriously spend a lot of time fixing the issues they previously pointed out, they go back and raise problems that should have been identified much earlier.
Here is another example. When I was in my second year of PhD, I submitted a paper to an academic conference. That paper was revised five or six times at that time, until they thought it was almost "final." However, now that I’m in my fourth year and want to submit the same paper to a journal, one of the supervisors reviewed it again and suddenly said that a major section had a problem and needed to be completely rewritten and this wasn't a simple issue like needing to add more data, but a fundamental writing/logic problem that required reworking. This made me wonder if he had even read that paper properly two years ago (even though he participated deeply in the earlier revisions at that time).
I'm very overwhelmed and about to break down because of their behavior. I want to ask: Is this normal? Because their behavior disrupts my work plans and causes me a lot of mental exhaustion.
