Like the field of psychology which surprisingly often produces results about very successful liberal-endorsed interventions (head start programs or growth mindset) that reliably return weaker results as they're tested more and finally stop reproducing altogether. These, sometimes massive, failures do impressively little to tame the smugness of their proponents.
You’ve just described the scientific method. That’s how it is intended, and that’s currently the best way to make decisions according to our knowledge. Failure is completely normal.
First, shoddy research getting published because it matches authors' and reviewers' bias is not some immanent part of the scientific method.
Second, that is not what the comment was about. It was about repeated debunking of reality's supposed liberal bias from which its fans consistently refuse to learn.
