Have a listen to the programme mate. It's like a very gentle Adam Curtis thing. There was an interesting bit on 'migration' of opinion, so people who share the same basic values tend to live in the same places. They promised maps on the programme website, but I can't find them. Even I could see the bias in that research though. People who naturally lean towards imagination and comfort with ambiguity were called 'open'. Those who favoured tradition and certainty 'neurotic'.
Great comments from a very right wing, true conservative Republican congresssman. He had been in Congress for 12 years, but changed his mind about climate change, and promptly massively lost the party primary for the next election. As he pointed out, there is nothing party political about climate change, but the narrrative has been told from the liberal perspective. He was a denier simply because Al Gore was a believer. Conservatives will not buy a liberal story, and vice versa. He changed when his son urged him to, went to Antarctica etc, and it cost him his job.
I'll give it a listen this week during my subsidised Xmas extension. Meanwhile, I heard on the radio today that both Netflix and Warner are interested in making a film about UKIP's Brexit triumph, based on a book written by Arron Banks. No more than Farage deserves of course, but who should play him I wonder?
