what's true is that "scientists" (being human individuals with irrational minds and neurotransmitter/hormone-driven reward systems, embedded in social hierarchies and status competitions) don't always rigorously apply the "scientific method" and of course the "scientific method" needs certain circumstances to work.
"Scientists" and groups of scientists can fall victim to all human failings as well as any other people, "scientist" is not some priest-like identity that sets someone apart or above from other humans.
And science can get discredited when it serves power or economic interests too much.
Or when producing enormous amounts of "studies", that are almost impossible to reproduce (and are often falsified when the attempt is made), so that "there is a study that confirms X" simply becomes a way to shut up opposition and support any political aim that happens to be connected enough to power, so that the studies confirming it have a chance to get financed.
Nevertheless if properly applied, a scientific approach as a way of weeding out wrong ideas still works pretty well ...
And even if scientists were infallible, scientific 'truths' will always be provisional. Science can only give us is a collection of rules of thumb for predicting future events. There is no logically necessary connection between causes and effects. Scientists infer 'laws' from repeated experiments and observations, but we can never be absolutely certain that these 'laws' will hold good for future experiments.
