I feel there is a lot of truth to this. An incident reading gives me a good mid-point exposure. Then if I feel the need, I can bias my exposure toward the highlights or shadows. So if I am photographing a steam locomotive, and the background is not too bright to become blown out by increasing my exposure, I can give an extra stop to capture some darker areas under the boiler, for example. But if I do need to render the background without over-exposing it, I can go with the incident reading, or perhaps just open up a cautious one-half stop. Then again if photographing something much brighter than average, an incident reading is good there, too, because a reflected light meter will over-react to that brightness; so that if I believe the meter, the scene will be underexposed so that it doesn't look much like it did in reality. In that case, I might stop down just a little, but not enough to ruin the shot. So an incident reading gives me a reliable reference point from which I can use my judgment. There is a reason why Hollywood cinematographers use incident meters (not saying they never take reflected readings)!
