a friend of a friend who did a stint in biomedical academia told me that the researchers in their field did not hold research coming from the medicine community in high regard
Knew a professor statistics from a world renowned institution. He worked in nephrology for 10-20 years and would tell many stories about the worst practices he's seen and researchers pushed him to allow.
Medicine was among the worst if not the worst according to him. Didn't really want much to do with it anymore. Basically a case of subpar statistical knowledge and bad incentives.
my impression is that inside these niches, people know each other personally, or are only separated by a small number of degrees. reputations form, etc.
so any paper they end up reading, most likely does not have completely unknown authors from completely unknown institutions.
without this information, yeah, it'd be harder to judge. surely anyone can find out anyone else's (using full name and institution) academic background online today, but it'd not be so easy to judge it without being an insider.
