//…would you care to identify factually incorrect information I’ve posted on this site?//
Certainly. You keep saying that Brexit costs the UK economy £80bn pa. As you know I’ve asked time and again for substantiation of that figure. The nearest you have come is to cite a study by Mr Springford, whose result was half that amount. And that is only an opinion. The only fact known is that nobody knows how much Brexit has cost the economy. That might not be the case if there had not been a war in Ukraine and a global pandemic, but there was. Any figures quoted are simply guestimates.
//On the 24 May 2016 (one month before the referendum), the polling data was 40% for both leave and remain, 14% don’t know, and 6% would not vote. Given the actual vote numbers, the polling data was pretty close.//
Were they? Let’s have a proper look to see how “pretty close” they really were:
Your poll said 40% Leave – the actual figure was 37.44%
Your poll said 40% Remain – the actual figure was 34.71%
Your poll said 6% would not vote – the actual figure was 27.85%
The don’t knows? Well, we don’t know. We don’t know whether they abstained (and so would be included in the 27.85%) or whether they voted (and so would be included in one or other of the choices). Of course the poll’s inaccuracy (and it was wildly inaccurate - anyone reading it had no chance of forecasting the result with any degree of certainty) was heavily influenced by the “Don’t Knows” and the “would not votes”. Your 2016 poll was so wildly adrift with that latter category (6% from the poll, 27% actual) as to make it virtually worthless. Remember the winning margin was only 2.73% of the electorate (or 3.78% of the votes cast). A poll finding 14% “don’t knows” and 6% of people not intending to vote (when that figure was wildly wrong) is meaningless when the result was always likely to be so close. Your “latest thoughts” poll is similarly deficient (leaving aside that its latest figures are two years old). It shows a combined percentage of don’t knows and would not votes as varying between 13% and 20% in the years 2017-2020. So the voting intentions up to 20% of the electorate, according to that poll, are effectively unknown. It is a meaningless poll (and I’d say that if it showed a majority who would prefer to stay).
