    My guess is that it’s related to the Weber-Fechner laws of perception. This is the same principle that explains why turning a second light on doesn’t make a room seem twice as bright. Fechner’s formulation is “the intensity of our sensation increases as the logarithm of an increase in energy rather than as rapidly as the increase.”
