But aren't scientists already supposed to do what you are talking about, what with all the stuff about Popperian falsification?
You mentioned global warming, vaccination etc which should have more debate but the problem seems to be how scientific endeavor is being shaped more and more by moneyed interests which brings the question as to whether science can always be trusted. IMO there is enough inherent problems within the science of global warming, vaccination, GMO to allow for heterodox views - why should dissent be left to the tinfoil hatters?. It is a fact that there is alot of inertia and individual bias because of being very personally invested within the many fields above or to take a more closer example - people working in the tech industry seem less interested about dangers of non-ionizing radiation emnating from cellphones/wifi.
I think that you are, in essence, pointing out that science on an individual level has been "bought out" because of the conflict of interest between pursuing a salary to pay a monthly mortgage and that of science possibly generating an inconvenient truth or two.
We certainly see no shortage of examples of this, look at the labyrinth of red tape the FDA has been forced to institute surrounding the field of medicine and clinical trials because of the fact that they can count on companies (and supposedly independent academic researchers) to lie-by-omission in reporting their results if given the legal (but no question about the moral/ethical) grounds to commit such lies of omission.
The old model was that the pursuit of science was independent of corporate conflicts of interest because the majority of scientific discovery was privately funded (monarchy and philanthropist established institutions) or products of an academic environment (universities and so on).
This model has changed in the post-WWII era with corporations R&D investments vastly outstripping that of the government, university, and private-sector investments.
Not that this model is broken or in need of change, evidently the model reflects our priorities as a species and as a culture. It is what it is because we enabled it, allow for it, and support it to be so. We get the society we deserve.
(it is ironic you mention cellphones and EMF...the irony was not lost on me when I worked on cellphones at TI that I was a willing hand in the creation of a market that was resulting in billions of people sticking these things next to their heads, I had concerns of the EMF effects on children and do to this day, but it was not even a discussion held in whispers at TI, we neither refuted it nor studied it, it was simply one of those discussions that was voluntarily never broached nor discussed...not that it was taboo or something, we all just wanted our paycheck and we knew we were one key medical study away from having the entire program at TI being torpedoed by lawsuits, personal motivation trumped scientific curiosity and concern at the time, we ALL wanted to be willfully ignorant of the danger until someone else proved otherwise)
