When you look into it, most analyses in most fields turn out to be what the second paragraph describes. They're just experienced enough to bury that fact under the rug. I appreciate these authors' naivete/idealism, and hope (but not really believe) such analyses in this field continue in this honest direction, without resorting to statistical and other standard trickery to get results.

You made me think carefully about it and you are totally right. It is in the very nature of how analyses work and how it should be, there is no shame on that.
