Doing things that are well meaning, but ineffective is not great policy. The simplest alternative to doing things that don't work is always not doing them. Better ideas are of course welcome, but not required.

I don't think that's how science/academia works. There is no such thing as a perfect study, there are always non-idealities and noise in the data. Good studies make well-justified efforts to account for these, OP is saying they don't believe this is the case here.

Regardless, your assertion that "oh well, the models will be totally different in a few months anyway, therefore any study done today is pointless" seems more than a stretch. How do you know they will be so different? How can you verify that today's studies are completely irrelevant?
