Nate Silver told the Scotsman last month that there was ‘virtually no chance’ of a Yes vote in next September’s independence referendum: ‘If you look at the polls, it’s pretty definite really where the No side is at 60-65 per cent and the Yes side is about 40 per cent or so.’ The comments were hardly revelatory, but they were seized on by media on both sides of the border as evidence that the independence campaign should pack up and go home. A few days later, Silver told an audience at the Edinburgh Book Festival that he was less than happy about the way his throwaway remarks had been interpreted. ‘Taking a comment based on a thirty-minute interview that becomes front page news is not the precedent I want to set,’ he said. With a year to go till the vote, both sides seem more interested in quoting wildly divergent opinion polls than discussing policy.
