No. I'm giving the benefit of the doubt to people who are educated professionals in their field who have presented research that likely withstood some level of editorial and peer review....over a random internet commenter who starts their comment with "I don't understand their methodology" and then proceeds to attempt to critique it.

I should have been more clear. By saying "I don't understand their methodology," I was hedging around the statement "their paper does not contain an adequate explanation of their methodology due to the nature of the complex systems they are modeling. By omitting information on how they constructed their controlling variables (and indeed the full scope of what variables they controlled for), the authors (perhaps inadvertently) cast doubt upon the conclusions they draw from their results."

Actually SSRN is a preprint server, so this has not been peer reviewed.

Has anyone ever told you that you can disagree with another person without taking an indignant and rude tone?
