I recently attended a political science conference where there was a workshop for early career researchers (ECR). During the workshop, a senior scholar mentioned that it is useful for him a journal editor to know whether the author is a senior scholar, mid career, or early career. Specifically, that when someone is an ECR, he tried to provide them with detailed comments even when the paper is rejected from the first round. However, I have also heard that most editors in social science, especially econ and polsci, don't pay much attention to cover letters.

I was wondering what editors in this forum think about this matter? And whether you may provide more/less feedback when someone is an ECR?
