An American journalist friend of mine spent four years in the U.K. a while back. I asked him about the PACE controversy and how it's played out in the UK media, the role of the Science Media Centre, etc. He gave a pretty succinct answer: People in the UK, reporters too, are used to taking sides. In this case, it's the scientific establishment vs. 'campaigners.' Pick a side. Well, reporters who spend their time in establishment circles tend to choose that side. It's easier, it conforms to their world view, it makes sources inside the establishment warmer to them, etc. Given how class-conscious the UK still is, this sounded like a reasonable (if partial) explanation. When BBC people are on the board of the SMC, it further cements the 'us-versus-them' mentality.
