To my knowledge, to this day, there are still exactly zero RCTs showing that masks were ever effective against COVID, and at least two major RCTs whose results indicate they are not very effective (there was no statistically significant benefit to masking). If, after two years of a world-wide pandemic, the best evidence we can put forth are low-quality observational studies which explicitly state they cannot show cau…
Are you willfully trying to propagate this idea? It seems like you must be, because there is a deluge of studies showing the effectiveness of masks - and the nuance and complexity of that statement. Throwing on a thin cloth mask that doesn't seal well doesn't do much of anything. Putting on an N95, well-fitted mask definitely helps tremendously. That you think there are "exactly zero" studies indicates you aren't eve…
I said there are zero RCTs, a type of study that can establish causation, and you respond, "there are lots of mask studies! You just aren't looking!" Your response literally contradicts nothing that I said. I even linked a BMJ-published opinion lamenting the fact that there are a lot of mask studies, but they are mostly low-quality. I'm going to guess you didn't bother reading it.
Not to mention that you tell me there is a deluge of studies showing the effectiveness of masks, but you can't even be bothered to cite one yourself. Lastly, you accuse me of sitting in an echo chamber, an accusation that is beyond baseless. What else would you be willing to accuse me of without a shred of evidence?
Your response is just another example that people don't follow the scientific method; they are driven by ideology and tribalism.
