If you aren't against RCTs, then I don't think we disagree? Your post certainly makes it sound like you feel there are better ways than RCTs to get an idea of how well things work.

And fair that "work" is not necessarily a binary answer. I think we can easily agree there is no panacea out there. But that doesn't mean you can't make pretty good learning based on the trials.

In common probabilistic game terms, we know that most hands are not as good as pocket aces at hold em. Even if we can say that the aces will not win near 20% of the time.
