Weird, I've always heard it called Gell Mann amnesia, not Knoll's law. Anyway, I think it's bullshit. I'm in tech and read tech news and most of the stuff I've read where I had personal experience has been accurate. Journalists generally are just people trying to do their jobs within the constraints they are given. The attacks on the media are ideologically driven by people that want to impose their view of the world on everyone else and don't want journalists ruining that.
