But if it's part of the Bose-Einstein statistics for bosons (I don't know)
then it is true.

The point seems to have been that MOST light is not scattered at all. 
Because of this, we see individual stars, and we see a yellowish sun and a
blue sky, not a brilliant white sky with no discernable solar disk, or 
stars.

Also the scattering is something like proportional to f^4, very frequency
dependent. Which is why the sky is blue and the sun is reddish at sunset
and lunar eclipses are reddish.
