If there are statistics in there, I try to check and double check that they are right (and if I cannot be sure, I say so). If there is perceived scientific or historical FACT in there, then I always make sure that what I reply is as factual as I can make it (and usually double check out on the web if I can).
Almost anything else - well if I reply to get a laugh, or to be a bit thought-provoking and that requires some "enhancement" to my answer, then well perhaps I'm a little less "accurate" than at other times.
