It is a logical fallacy to ignore an argument because of one small distruth or lie. Now that's out the way... Unfortunately I'm talking about people's emotions and their decision to trust a source of information. This is clearly NOT a purely logical situation. There is a false expectation that govt groups are always correct and don't admit mistakes,even if they were correct as they could be at the time. Failure to own these mistakes publically and discuss the shortcomings and failings puts you into the same level of distrust as a scientist view's a snake oil salesman. I take part on science outreach and one of the most damming things is having to explain when some media celebrity scientist said something utterly stupid and not correct. You then get the envetable "who can i trust" argument and the best way to resolve that is to share more information in a respectable slow and distant way... Aka actually educating people.
