Physical ident is more efficient and flexible than construct ident, eh? That's always made intuitive sense to me (eg the ident mechanism of the mousetrap), but

Physical ident is more efficient and flexible than construct ident, eh? That's always made intuitive sense to me (eg the ident mechanism of the mousetrap), but I've never seen it explained so clearly. (cue pun about "duck typing") I think you are right that this has implications for a lot of things, not least graphic design. If you have a good grasp of how people respond to different elements you could guide their actions even more than now.
