Most scientific hypotheses fail. So most scientists are usually WRONG. That is not a bad thing. Proving something does not work is knowledge too. But these days scientists appear more like game show hosts. They will say anything knowing hardly anyone will dispute it, and scientific refutation does not usually get reports. Political correctness takes precedent over the scientific method.
This leads to stories worthy of Monty Python. The most recent I have seen was a scientist who died of plague. He was working with a genetically modified version of plague that should have been non-infectious. So they implemented no bio-hazard controls. Since they really had no clue what they were doing, they actually created a version of plague optimized for the genetic condition common to descendants of plague survivors. The scientist died, and a bio-hazard incident on the campus. Talk about Darwin Awards.
In shot take all pronouncements Deus ex Scientifica with a large grain of sand, and wait a few years for the actual physical proof.
