TLDR: Is it normal that an applicant for a limited term fellowship should have to justify why that fellowship would be more advantageous than a permanent academic position? If so, why?
The details of my specific situation:
I recently applied for a 5-year research fellowship in the UK. The fellowship is quite competitive and prestigious. If approved it would provide funding for me to set up my own research group at a UK university.
I just received the referee reports. There are four reports, of which three are very positive. The fourth is generally positive about the research content and my track record, but identifies what the reviewer believes are some "clear weaknesses" in the application. Given the competitive nature of these grants this last not-so-positive review likely kills my chances of getting the fellowship, although I do have a chance to respond to the reports.
One of the "weaknesses" identified by this reviewer, was that I had not sufficiently justified why receiving the fellowship would be more beneficial to me than simply being appointed as a lecturer at a UK university. I found this comment frankly unreasonable and nonsensical, but maybe I am simply responding emotionally, and so my question whether this is generally considered a legitimate reason to criticise a grant proposal and what the reasoning behind this is?
Bear in mind that in the UK a position as Lecturer, is generally a long term academic post with both research and teaching responsibilities. Being appointed as a lecturer in the UK is broadly equivalent to getting a tenure-track Assistant Professor position in the US. So the reviewer is essentially saying "you shouldn't get the 5 year fellowship because it would be better if you had a permanent position".
The true (and in my opinion blindingly obvious) response to this is: "of course I would like to have a Lecturer position, but such positions at good universities with research strength in my area, are extremely rare". I can't really write that in the response, because it would sound like I wasn't taking the reviewer seriously, but that's the truth. It seems to me unreasonable that I have to justify why the fellowship would be better than an alternative that barely exists.
