Of course, yet I wonder if it would have made a blind bit of difference in the face of "project fear" claims, because I suspect (from the sample of leave voters I know) that they didn't vote leave based on economic impact papers or claims, but on other issues - immigration, sovereignty, and all that - intangible arguments, mostly. I genuinely only know two people who used rational argument to back up their position to leave - one of them is @Awol on here, and another is a work colleague. All the others, and there are plenty, were more emotion based. And for those you can't use reason to get them from a position they got to without using reasoning.
