Long held belief confirmed (sort of)

When King Duncan arrives at Macbeth's castle and is told of the death of the traitor Cawdor, he remarks, "There's no art to tell the mind's construction in the face," by which he means we have no way of telling what a person's like, or is likely to be thinking at the moment, from his expression. The latter, as in poker face, is certainly true, but I've always argued that you can tell quite a bit about a person's character, personality etc. from his physiognomy. Now there's a bit of science that confirms that thery.
