Imagine an experienced surgeon in the middle of a delicate six-hour procedure where the surgeon responds to a series of unexpected emergencies being evaluated by a computer based on data gathered from a fifteen-minute snapshot visit by a general practitioner who has never performed an operation.

Imagine evaluating a baseball player who goes three for four with a couple of home runs and five or six runs batted in based on the one time during the game when he struck out badly.

Imagine a driver with a clean record for thirty years who has his or her license suspended because a car they owned was photographed going through a red light, when perhaps there was an emergency, perhaps he or she was not even driving the car, or perhaps there was a mechanical glitch with the light, camera, or computer.

Now imagine a teacher who adjusts instruction because of important questions introduced by students who is told the lesson is unsatisfactory because it did not follow the prescribed scripted lesson plan and because during the fifteen minutes the observer was in the room they failed to see what they were looking for but what might have actually happened before they arrived or after they left.
