Excellent ten minutes from Tom Shakespeare on A Point Of View this morning on Radio 4. His theme was changing your mind. Among a number of quotes germane to this thread, he quoted Bertrand Russell thus: "The fundamental cause of the trouble is that in the modern world the stupid are cocksure while the intelligent are full of doubt.” Incredibly inappropriately, I instantly heard that as "...leavers are cocksure while remainers are full of doubt." I'm just off to confession. But give it a listen if you missed it.
