I would like to post this in the Aviation Safety and Security Checkpoint Screening and Abuse in the USA forum, just because I think that one gets more eyeballs, but maybe I'll settle for reposting the gist of it in every thread I can think of. Because the issue of presenting facts and rational argument has come up repeatedly at TUG and will continue to. Paraphrasing one member, I forget who, recently: "most people are smart; when presented with the facts, they'll get it." Not only have I always thought that was hopelessly sanguine, and not only has my own experience presenting facts for the past 19 months proved otherwise, but here's a July article from the Boston Globe that presents some depressing facts of its own: How facts backfire Researchers discover a surprising threat to democracy: our brains On the limits of reason, and the power of slapping someone in the face metaphorically -- something else we have discussed endlessly: I'm reminded of a certain Baltimore Sun reporter, whom you all have heard me quote several times, who asked me explicitly for facts in an email last year, then when I replied saying, 'coming right up', wrote me back immediately saying, 'It doesn't matter; I don't care.' I have this in writing. This is what we're up against.
