Debunked 'Stanford' mask study headed for retraction

Hammster said:

My “complaint” about masks is that they are mostly ineffective. This is based on multiple studies conducted well before Covid. I bring that up because there was no agenda in conducting the various studies.

Which studies? I ask, because there was a spike in interest in mask effectiveness during COVID-19. When meta-analyses of pre-COVID-19 studies were performed, masks showed a 70% to 80% efficacy in preventing the spread of viruses.

Here's two such meta-analyses:

When studies were conducted during COVID-19, they found the same thing - face masks (particularly N95 or similar, but also basic cloth masks) were effective at reducing the transmission of COVID-19. And also worked to reduce the severity of viral infections.

Finally, we get to the meta-analysis stage of SARS-CoV2. These 2020 studies (controlled and retrospective) range from a hair salon and naval personnel in the US, to household members in Beijing, and public transport users in Germany. They all found that mask wearing reduced transmission rates.

Effectiveness of Mask Wearing to Control Community Spread of SARS-CoV-2

@Hammster Do these convince you that masks are effective at limiting the spread of COVID-19? If not, why?

No, they don’t.

COMMENTARY: Masks-for-all for COVID-19 not based on sound data

There are multiple studies linked on this page that show that real world mask wearing is ineffective. I don’t expect you to be convinced, but the data is there.

Do we support cloth mask wearing where mandated?
Despite the current limited scientific data detailing their effectiveness, we support the wearing of face coverings by the public when mandated and when in close contact with people whose infection status they don't know.

Your source says the following:


They say wear a mask. We also have more studies now showing the effectiveness of masks s @Gene2memE shared for us.

Obviously you didn’t read the whole thing.

I did. They discussed the limitations of cloth masks. How they are not as effective as surgical masks and are no replacement for physical distancing and isolation. That those two should be pushed more than mask wearing. But they still ended up recommended following mandates to wear masks.

Hammster said:

Actually they ended up saying that there’s no discernible benefit to wearing masks. The point, though, is that so many consider mask wearing to be settled science. It’s far from that.

No they ended up saying they felt there was not a study proving that masks were effective. A very different thing.

When a mechanism is known and demonstrated that shows somethnig is effective, which is the case with masks, then it creates major ethical issues with doing a study controled study. This limits ethical researchers to using information otherwise available. That information has shown masks to be effective.

But of course just one bad study that shows what you want trumps dozens of better work that shows the opposite. (Pun intended).

You are sorely mistaken if you think it’s the only one. I just picked that one to start with.

There’s a study on that, too.

Curious as why you don't provide links to all of theses "studies" you are mentioning.

My “complaint” about vaccines is that there are no long-term studies that show the effects on humans after two and five years.

Strathos said:

But that is false.



That is true, but are you suggesting that we wait five years to get vaccinated, and let millions of more people die?

Hammster said:

Millions won’t die.

Strathos said:

Millions have already died. Refusing to wear masks and take vaccines will just multiply that number.

Hammster said:

Not really.

Strathos said:

Yes, really.

Hammster said:

Where does that show that masks and vaccines will help?
