First, a longitudinal study is a study of studies. Not necessarily. In my field, a longitudinal study is a repeated sampling of subjects across time, interview folk when they are 20, 30, 40, etc. Many long term health studies are done this way. One might do a study of studies in which one compared environmental studies done 200 years ago with ones done later. In that case, and as I read further in your post, I gather that's what you mean, sorry, reading and typing at the same time is not good. And, given that, I agree with your conclusion about the methodology. Crap in, crap out. That's true of more research than we would like to admit.
