The problem isn't science it's how some people use it.The idea that science has caused more harm than good [for humans] is of course easy to debunk, but to be fair, it is possible to argue that science could ultimately be the end of humans, if you believe in ideas like the Great Filter and that it has not yet happened. It's not unthinkable that science can take us to the point that it enables a few individuals to destroy humankind, or, as science fiction will have it, machines themselves decide to do away with humans. It's very hard to tell whether it's an unavoidable consequence of scientific progress.
not to mention that uninformed voters are much more easily manipulated, which is exactly what we see is going on.I see nothing ethical in an uninformed democracy.
