Polling experts just fired a serious warning shot about the outcome of Britain's referendum on whether it should leave the European Union on June 23.Speaking at an event titled "The Euro Referendum: Will the pollsters get it wrong again?" - which was hosted by The Media Society - a panel of experts said they feared the outcome could be quite different to the projections of the final opinion polls.Advertisement
Peter Kellner, former president of one of Britain's most prestigious polling agencies YouGov, told the audience: "I am not at all confident that the final average poll will be within 2-3 points of the final poll."
Political scientist Professor John Curtice, who was also on the four-person panel, agreed.He said: "The problem with the EU referendum is that pollsters are trying to estimate accurately something which they haven't had to [accurately predict] before."
He added: "You shouldn't be surprised that the polls are having some difficulty."Kellner and Professor Curtice were joined on the panel by The Times data editor Megan Lucero, and Matt Singh, who rose to fame last year as the only pollster who predicted the General Election result correctly.The panel agreed that one of the major reasons why pollsters are struggling to predict how the vote will turn out next month is that the referendum presents something virtually brand new for them to analyse, with no truly relevant historical information to use as a base.Advertisement
As Professor Curtis said: "How people voted in last year's general election is not a good way of predicting how people will vote in this referendum."
Singh, who heads non-partisan statistical analysis group Number Cruncher, agreed with Kellner. He explained: "The methods used by most pollsters can still only reach a certain type of person."
The latest What The UK Thinks Poll of Polls, based on surveys published over the last two weeks, said that the Leave and Remain campaigns are virtually neck-and-neck with just six weeks to go until the referendum.Prior to this survey, however, Britain's most popular polling agencies were releasing very different forecasts of how the vote will turn out. BI has also discussed in the past how flaws in how polls are conducted meant that they should always be treated with a degree of scrutiny.Advertisement
