Let's assume that when I say statistics I'm talking about the scientific application of statistics and not Fox New's use of statistics, now to your questions: 1. Not always, but that is the nature of scientific research and you should know this. 2. I would say that they would, if you found yourself or a member of your family and/or friends were affected by a mental illness. Which, by the way, is very, very likely. In regards to common sense, you can't always rely on it, and there is research to prove this. As for your utilitarian measurement of what is useful to you or bullshit, great! You sound like you'd make a great engineer, as opposed to a research scientist. Though don't hate on the researchers, they discovered some of the things you take for granted in your day to day application of what is 'not bullshit'.
