When writing a paper with a collaborator, they didn't like that I used the word "exciting" in the abstract since they said that they don't like when people use personal personal qualifiers in writing papers. In particular my sentence was
"With these exciting results in mind, we study..."
(where the 'results' I am referring to are from a few recent experimental papers which I had nothing to do with). I initially wrote it in this way to emphasize that the recent results are interesting. Is this truly something that should be avoided?
Note: If it makes any difference I work in physics.
