Masks don’t work until they do I mean don’t

The Science went from “they don’t work” to “they do” and now they’re back to “they don’t.”

The new takes are coming so fast it can make you as dizzy as wearing an N95 mask for five minutes straight.

A simple cloth mask — no matter how cute the fabric is — will not cut it anymore, according to Dr. Erica Swegler of Austin, Texas. However, the family physician with Village Medical said a cloth mask with a filter added into it would be better if there are no other options available to someone.

Dr. Swegler said a cloth mask became more obsolete in terms of protecting someone well before omicron emerged in the U.S.

The delta variant somehow had been able to evade that [cloth mask] barrier quite nicely, and it is just not sufficient,” Dr. Swegler said.

I love the use of “somehow” in that quote, indicating she has never heard that respiratory viruses spread via smoke-like aerosols, yet is somehow deemed sufficiently competent to advise millions on how to protect themselves from the deadliest virus known to humankind.

Why and how do these changes to the narrative happen?

It’s utter bullshit. But not quite lies either.

I discuss the dynamics here.
