hmm, quite a hard question.
I think.. people tend to be careless toward scientists. I mean, one of human's nature is to decline something he doesn't know until he sees the prove with his own eyes. but even that way, some still refuse to believe in what they see. I can understand why people lose faith in authority because I feel so too, though. but that also depends on what they say. I think the society can choose which things scientists said that they must really pay attention to and what not.
