Now this is something worth watching. Particularly if you still believe that the talking heads in the media know what they're talking about. It's lightweight, as in it doesn't go into to much depth. And personally, I don't think it makes enough of a distinction between the expert in the media and the experts who actually know what they are talking about. Who do exist. It is mainly, I think about the dilution of the meaning of the word expert. Which is, I believe a major problem for us as a society. It's not something you can regulate though so it's going to remain a problem. Still, watch this, I find that most things with Ben Goldacre in tend to be worth watching.
