Regardless of this discussion, there is way too much of that kind of thing going on today. So many people watch a video or read a wiki article or listen to someone on a message board who "seems to know" what they are talking about and then think they can speak intelligently on a subject. It's frightening. There are a lot of people out there who seem to know what they are talking about because they dress it up and make it sound good. And that doesn't even take into account personal biases.
I'm reminded of a professor I once had who as a kid would read about things and believe them but when he got older and started researching those same topics himself, he realized how inaccurate and skewed some of those books were. I realize not everyone can be experts on everything (despite the fact that some people here act like they think they are) but there has to be a better way, something in between cursory reviews of information and full on serious research.
