Why would I read it if I don't have the scientific knowledge to know whether is true or not
How come you are not educated? In today's world the Internet allows free access to all of human knowledge. Typically a paper can be understood by reading the references.
and you don't have it either.
This research paper is not comprehensible? Why not? It is written in English. Your claim has zero substance; in fact, research papers can be understood by anyone, even technical papers can be easily grasped in a general sense. Just because I am not qualified to "peer review" a paper does not make it impossible to undersrand by the general public.
Why do you believe it is the real question. I would ask you again, are you a scientist or expert in these things? If not, why believe any of these papers?
Everyone learns about science in school, anyone who went to college can read and understand a research paper, even one outside their field, given enough study.
Why believe any paper at all for that matter? Published papers are written by experts and there is no difficulty in understanding them even if one is not an expert oneself. Your latest "argument" is totally circular and not based on evidence.
