2) In low light reducing exposure should also make things look more normal in a print.
That's something I read about in Gene Nocon's Darkroom Printing book. The idea being that if you took a 'normal' light meter reading at night or a dark scene like a band on a stage, the meter will do what it always does and give the correct exposure for an 18% grey scene. A night or low light scene is significantly lower than 18% brightness so less exposure is needed than the meter suggests..
