Additional research based knowledge of the costs imposed on people ....ref.1
I cannot imagine a chemist or physicist (or industrial hygienist) writing this sentence. How does one make any claim to anything in a scientific peer-reviewed journal if it isn't researched based? I suppose the assumption excludes personal opinions and the editorial section.
I've seen this several times in this course's readings. It's even defined somewhere in the text. It's the social science method to claim scientific validity for a subject most physical scientists don't think is science.
