Perhaps the Scots tend to one-box, whereas the English tend to two-box.
My intuition is that two-boxing is the correct move in this scenario where the Predictor always fills the box with $1M for the Scots and never for the English. An Englishman has no hope of walking away with the $1M, so why should he one-box? He could wind up being one of the typical Englishmen who walk away with $1000, or one of the atypical Englishmen who walk away with $0, but he is not going to wind up being an Englishman who walks away with $1M because those don’t exist and he is not going to wind up being a Scottish millionaire because he is English.
EDT might also recommend two-boxing in this scenario, because empirically p($1M | English & one-box) = 0.
