"So much faith"? People are just following the science. Are you really arguing that because one bad situation has occurred involving pharmaceutical companies, we should assume every new drug or treatment is bogus or based on evil motives?
Compared to the "hard" sciences, medicine has not very high standards. And trials are completely profit-motivated, that's a bad incentive. These trials are conducted by the same companies who had no qualms to sell highly addictive stuff to people. Why should I trust that the data they publish is the data they collected?
If somebody said I've discovered time travel and the onus is on you to prove me wrong you'd call them out.
Explain the science or gtfo
Edit: not accusing anyone in particular, just e.g. when some mayor says "we're following the science" I know he's just parroting what he's been told because he has no scientific training whatsoever.
