A GMO could be created to be extremely dangerous, just like a prescription medicine could and has been created which is extremely dangerous. The problem is that we're asked to trust people whose immediate interests do not always align with ours. We've seen prescriptions forced through with inadequate testing, so there's no reason to believe that every GMO is going to be adequately tested. The current atmosphere of hostility seems to be helping that testing happen.
The base problem is that we have a society of people whose interests are aligned against each other and a system meant to encourage that kind of competition.
This. This might be one of the roots of the lack of trust. And given that people get abused by others all the time, it's really hard for me to blame people mistrusting research done by companies - especially if you don't have even basic understanding of the scientific issues involved, which most people don't have - partially thanks to broken education system, and partially because well, why should they? Not everyone will love science, those who don't should be able to just trust those of us who do. But now they can't.
Ask a genetic researcher if "GMOs can harm humans" and the answer will likely be, "Probably not". But this actually means - "I can conceive of nothing but the most fantastic route for that to happen. And even if it did it would have to happen by a route currently unknown or at the edge of our entire field." When in reality the public clings to really strange notions that truly are scientifically incorrect.
You can make the argument that being correct for the wrong reasons has its advantages, but in real life no single action ever taken is without risk. It is precisely the scientist who has dedicated her career to her work that understands (and even thrives in) its complexity.
I agree that arrogance of some scientists is a part of the problem (I'd say caused by communication problems - scientists and non-scientists are often so far apart in their understanding of various subjects that it's very hard for those two groups to communicate with each other).
Also, people saying about "limits of research" are often doing this to support their refusal to accept conclusions. If you can't find any rational argument against a thesis, you can always say that the whole process is wrong and then continue to believe whatever you want to believe. "But there's always a chance, right?".
I can't speak for TeMPOraL, but I've never heard anyone claim that science is infallible--and it's certainly not implied by their comment.
Science believers simply recognize that scientifically-vetted ideas are _the most likely to be true_.
Sometimes science is wrong. Often. Maybe even usually. Science is very clearly the most reliable truth-finding mechanism we have.
The options aren't sometimes-wrong science v. omniscience. It's sometimes-wrong science v. more-often-wrong everything else.
Characterizing belief in scientific findings as absolute, undoubting faith is completely inaccurate.
Why is that? Another reason people lost trust is the arrogance of some scientist that seem to ignore the complexity of their subjects and don't see the limits of their research.
Also people like you that believe that everything that has gone trough a scientific study must be true, science can also get it wrong sometimes, don't stop thinking and questioning.
