It seems that the BBC is much like any other large news organisation; perhaps better than some and perhaps worse than others. It has time pressures to produce something that is current and topical. And this can lead to poor research, poor quality assurance and poor implementation with biased reporting and inaccurate information. I certainly don’t buy into any romantic notions or myths that the BBC is impartial and infallible.
DC’s Improbable Science has an article describing “some truly appalling reporting of science by the BBC” at http://www.dcscience.net/?p=2813. We definitely do need to be on the guard against nonsense and DC’s Improbable Science blog is one of those places to allows us to do that.
