I don't see them as the same either but most are routinized in different ways and thus somewhat predictable. Self-interest is in there too in that they would like things to go in their preconceived directions. It's odd for an EII not to immediately notice being ordered around; they tend to almost insist on autonomy and a certain amount of distance. I can see maybe an Ip not noticing - for a short while......
