Then there is the global warming "debate". The anti Vaccination crap.
Also the last few years have seen surge in "Everything they said about eating fat / salt /alcohol was wrong".
OK, I have given examples of crap science reporting, but I think the public relate back to it that climate scientists are just after funding. Or that scientists are always wrong. Extrapolate a bit and you will get to where the average Joe is.
Maybe I feel a similarly way about certain religious people. Certainly in the States there seems to be some bug money in that. Its not too hard to see the public's perception of scientists as a mirror image of that.
