For over a year I have been developing my thesis and there have been many issues in the process as neither me or my supervisor are experts in the field I am working in. My supervisor has been aware of my model and has, routinely, told me that they think my model is okay. So, I carried on under that assumption.
It is one and a half months away from when I was supposed to defend and I was told that I need to make a big change in my model because the results are too 'intuitive'. So I am feeling like I have to scramble to try and adjust the model so that I can give better looking results.
I am not sure what to do. I have no results I can write about and I am a month and a half away from trying to graduate, and over the 2 year expectation, and at this pace, it seems like a possibility that could continue into the new year and approach the 2.5 year mark. I'm not sure whether I should try to just defend the results that I had originally, even knowing that they are intuitive, or keep trying to find a way to change how my results come out to be less intuitive.
My supervisor told me that if I don't change my model, I run the risk of getting 'major revisions' and in my defense, if surely probed about the problem, I can't respond with 'well, my supervisor and I agreed this formulation was okay, and then one month ago she asked me to change it, but I did not feel I was able to make the desired changes'.
So I am feeling like I am in a very difficult position and I am wondering if it is common for people to defend their work knowing that they might get sent back for major revisions, and how to deal with those revisions when you are not feeling supported? It's unfortunate, because had I been told that my supervisor disagreed with the model several months ago, I could spend the mental energy to make these changes, but now I just feel like i'm scrambling to put something out i'm not proud of.
