I have currently a disagreement with my advisor regarding the journal we should send our paper.
My advisor wants to send it to a very specialized journal with low impact factor, and to add a lot of details in the main text. On the other hand I believe the topic is of interest for several communities and want to push the jargon to the appendix, have a polished main text, and try high impact factor journals. Also I want to change fields after my PhD, so a good paper that my prospective boss could understand would be a plus.
He says he doesn't want to put in the effort for a high impact journal, and probably doesn't know also, and that he would prefer to spend his time reading a book or doing new stuff. (He is close to retirement)
I am willing to put in the effort to polish the paper alone, but still he is not satisfied.
For background, our previous paper was sent to a low IF journal, and was accepted immediately with minor revisions. For that paper also we had disagreements how much details to add in the main text and where to send it (and I stepped back). The result is that the gist of the paper got obscured, some big shots read the paper, cited it, but presented the result better, and now they get all the citations.
Similar things have happened to him more than once in the past.
How should I navigate this without offending him?
For the previous paper I stepped back, but now I cringe every time I read it. I feel that although he is smart, he doesn't really know how to communicate effectively, and he is also not interested to try. But this is something that I feel that I have, or at least I am willing to spend time to improve.
