I believe you are making a conclusion that neither the article nor science in general makes. The differences in preference are exhibited, but whether they have a biological root (and what outcomes we should target) do not have strong evidence.

Even peer review is not a stamp of quality, but it at least signals "some set of folks have broadly reviewed this and consider it well constructed."
Whether it's sociology or fusion or battery tech -- we shouldn't put much value on preprint articles.
