I'm uncomfortable about generating strong generalized conclusions based on such methodology.
You should be. This can't possibly work.
This is a journal that also published and later defended work premised on psychic ability, though.
It's a serious journal, as I understand it. But they take flyers. This definitely seems like one.
While psychic powers have been thoroughly tested and debunked, isn't the point of science to entertain ideas that seem crazy, as long as they are tested scientifically?
I'm sure there's also a peer-reviewed journal of flat Earth science, too, with papers about the Atmosflat.
