At greater risk of exposing my misinterpretation of it than jat850, my understanding was that his domain knowledge allows him to solve the problem directly rather than fumbling around with generic solutions (perhaps solving it accidentally). Some quality of the action affects the outcome, even though the approach is pretty much the same. Some problems with my router call for a simple power cycle; others call for a power cycle with ~30 seconds unplugged from power. Someone without much knowledge of the router might do the same thing as me (power cycle), and it might even occasionally work (if s/he unplugs it, goes to make lunch, and comes back), but my domain knowledge enables me to solve the problem more consistently (seemingly magically).
