What do you do when people quote statistics like this in real life? I usually just sit there like an insincere fool and remain quiet or offer lukewarm agreement. I can't bring myself to tell them that I disagree because I don't want to be rude but at the same time my current system is not working.

I found that, for me at least, it kinda works to not outright disagree, but to say that you 'read an article' that disputed said fact and now you're confused about whether it's actually true. I usually see one of three things happening: they say something along the lines of "oh, I don't know a lot about that, so I can't tell you" and the conversation moves on, they tell you "it's obviously bullshit, because I read it in $magazine", or they'll engage with it to try and lift your confusion. In the latter case, you can feed them arguments and facts, but since it's not a debate ("you're wrong" - "no, YOU are wrong"), it's easier for them to see when/where their beliefs fall short.

Simply share the fact you know, be prepared to explain how you know that it's reliable, what are the implications of the difference.

In my experience people listen to people who can explain things, not just claim that something is wrong/false.
