That's a good point. I tend to stay away from negative thinking about hot topics like this for that very reason. Even though I have my doubts about something, I tend to keep it to myself because I don't want to bring people down and anyway someone might come up with a way to look at, or take action in a positive light.

But I still feel its important for people to act from their own values, right or wrong, and not from a "hey trust the science" mentality which reminds me of majority thinking. Just because a lot of people have come to the conclusion that the science is sound, it doesn't make them right. There are plenty of situations where decided by majority viewpoints have been wrong.

Science done well is distrustful of its own results. The key is to trust science practiced by trustworthy institutions and individuals and reported on in an accurate and informative way. Similar to good journalism, trust should be earned and verified at every level. Not every time, that isn't reasonable, but enough that you aren't surprised at what you find when you do additional checking. Check sources. Look for conflicts of interest. Survey the field. These are all basic things that people think they do but often don't.

I'll also say that that 'I don't trust science' implies that the scientific method is somehow corrupt. The scientific method is a thing that can be used well or badly. 'I don't trust science' is like saying 'I don't trust statistics'. The wrong person can use out of context science, done well, to imply totally absurd things.
