It's that feeling of being watched - yes. I can't quantify it but since I've been accidentally promoted into an office (only managers are supposed to have offices in this company but my department's been budded off from the mothership) from the bullpen I feel more productive, stay later each day, and generally feel more confident and at peace all day long. One of my cow-workers who's still under the all seeing eye has a mirror on the aisle-facing wall of his cube. That would probably help had I tried it. My old cube was not only on the middle aisle but had one of those smokey camera housings mounted on the ceiling allegedly facing the door to the outside.
