This confusion is rampant in the business world. Some people prefer to bamboozle and be bamboozled by case studies, some people prefer to bamboozle and be bamboozled by pie charts. Powerpoint is a common medium for both. However, despite their differences, they share their audience - people who can't do a good analysis and have no idea what one would look like. Inevitably, if this realization ever sinks in it will have to be worded in a way that doesn't make it sound like there's anything wrong with the people who don't know what they're doing. Now that journalists have started to phrase it in a way that makes it sound like the "facts," are at fault, I think it has a good chance of becoming accepted.
