Maybe, maybe not. It's been fairly inconclusive. But to this point, if there are no significant downsides to at least trying it, why not try it?

At the risk of a thread derailment which is not my intent, I think this illustrates your concern about confirmation bias.
Is it fair to say that you are biased to trust information simply because it is published in JAMA? I certainly was a couple years ago. If so, it would make sense why you would link that study, especially in in light of your past/current skepticism about IVM.
On the other hand, I read the first few paragraphs and I can immediately see that the study design is nothing like the protocols that dozens of doctors using ivermectin have used to literally save thousands of patients with either zero or low single digit deaths.
The three key factors those docs have been sharing with anyone who will listen is that you treat immediately (not wait until day 7 (!) of symptoms as in the study, you treat until the symptoms resolve (not just stop at day 3 regardless of patient condition) and you treat with complementary vitamins and minerals like C, D and zinc.
There are dozens of quality studies that show that early IVM (or hcq or even better, fluvoxamine) treatment works very well. And yet, the JAMA publishes this paper that confirms the skeptical view, by not following the protocol that has been proven with tens of thousands of lives saved. The ACTIV6 trials have the same issues, and ironically when non-biased docs dug into the TOGETHER data it actually still showed benefit from IVM!
One might say, well, this protocol was designed just to test that scenario so we can learn something about IVM, but at this point that is a waste of time and resources that does more harm than good, especially because the result is used to further suppress the effective protocols just because they use IVM.
So, I agree with you... Confirmation bias is powerful and widespread. I don't mind having my own pointed out to me for me to examine as it seems you don't either, and I think that's key to getting to whatever truth is possible.
