So what are people supposed to take as evidence? Unsubstantiated claims? Or research that has been verified by other researchers?
Trouble is that in today's age, we see far too much corporate and special interest "science," where data is either being faked or experiments are constructed in such a way that yields data in a way to create desired outcome.
We must always compare apples to apples.
The pharmaceutical industry is a blaring example of a special intrest that engages in constructing Science to have a desired outcome (bias and agenda).
