A thread for anyone who is infuriated by and/or enjoys reading about this type of stuff. I love it, but annoyingly at the moment I can't think of any examples, other than dull work-related ones. For example, if you're looking at something as a proportion of the whole, then you can't consider one thing in isolation. For example, as Trills mentioned on another thread, let's assume heart disease is the biggest killer of adults (which I believe it is). Let's assume 10% of deaths to adults in 1950 were of heart disease, compared to 42% now. Shocking rise? Probably not.
Plus I will attempt to explain the Monty Hall (think that's the name) problem to anyone who is interested and who doesn't already know it.
