I've also been kinda curious about the research in favor of structured interviews, because as far as I've seen they're generally drawing their conclusions based on "interviewer-predicted performance" vs "actual performance".

How the heck do you measure actual, repeatable performance? Or skill? Income / promotions / etc is very frequently a horrifically biased metric, for similar reasons to interviews, and we have much larger mountains of evidence showing that to be the case. It seems like there's a pretty good chance these studies are just measuring relative bias between interviewers and the interviewee's management, and concluding interviews are done poorly when they disagree with management. i.e. "structured interviews force people to think more like managers" rather than "structured interviews more accurately measure skill".

Using one bad measuring tool to conclude another tool is bad seems... problematic at best. I will grant that "interviews should measure what managers measure" is often what businesses want in bulk, but that does not seem like a particularly good thing to me.
