Science gets a bad reputation because we're no longer getting information from the source. Instead, we get science from every pundit who has a political or philosophical axe to grind. Facts can be misused in all kinds of creative ways, but people don't like being manipulated if/when they finally realize what's going on. Because of this hack/dogma->science association, people have become skeptical to the point of incredulity when presented with scientific evidence.
It certainly doesn't help that we've created negative incentives at every turn for the scientists in question. Funding, exposure, reputation, and influence are all peddled to the researchers in order to control the output of their work. Scientists are people too, and everybody needs to live on something other than hope, dreams, and idealism.
