What NPR is NOT telling their audience, is that nobody in the history of the world has ever demonstrated that its even possible to find a vaccine problem by using a study.
We all know COVID vaccines cause myocarditis, and blood clots,
But we don’t know that because some vaccine scientist did a study.
We know that because of “anecdotal” reports,
And as we all know, in clown world, “anecdotal” means “didn’t happen”
I mean at this point the Scientific process is so corrupt that you find ‘studies’ claiming almost anything you want. It depends on whose funding the studies that determines the results
the null hypothesis is like the presumption of innocence, but for an inanimate object.
sounds nice, right? wrong!
vaccine "studies" BEGIN with the presumption of innocence, and then they don't try very hard to disprove their own assumptions.
so they start their study with the ASSUMPTION that vaccines DO NOT cause autism,
and then they arbitrarily set "statistical significance" to 5%,
when autism has an incidence rate of 1 in 68 kids, or about 1.47%
and then they say, "wE cAnT FiNd tHe EviDeNcE"
without ever bothering to mention that they will never, ever "find the evidence", with their inherently dishonest methods
