Wait. Does this pass for science in these fields, psychology and medicine? They summarize various statistics from prior papers as if they are trends across space and time (hello sample bias, are there papers that contradict their claims they are omitting because it doesn't fit their thesis?) and then make broad conclusions based on anecdotal evidence and sweeping theories. This should barely pass as a "kids these day…
You've evidently never heard of a meta-analysis.
Just read a bunch of papers, summarize them, and write a new paper. Scientific research had devolved to the point, that no one knew how to do new research.
