Helena Cronin , a philosopher at the London School of Economics, turns her attention to why men appear far more successful than women, by persistently walking off with the top positions and prizes in life — from being heads of state to winning Nobels.
Dr Cronin used to think it was down to sex differences in innate talents, tastes and temperament. But now she believes it has also something to do with the fact that women cluster around a statistical average, whereas men are more likely to be represented at the extreme ends of the normal spectrum — both at the top and the bottom.
Some replies to the Edge question ponder the perennial problem of God. Professor Patrick Bateson  of Cambridge University has changed his mind on what to call himself after meeting a virulent creationist. He is no longer an agnostic but an atheist. Meanwhile the actor and writer Alan Alda  said that he has changed his mind about God — twice.
What have you changed your mind about? Why?
