I'm not sure this is true. To me it seems politeness is a mostly self-reinforcing cultural phenomenon that doesn't have any real objective basis. How much of your speech and gestures you're expected to use for etiquette without it carrying any real semantic meaning varies greatly between different cultures. Countries with a lot of politeness (e.g. Japan) don't seem to be any better at communicating and cooperating than countries with very little (e.g. Finland). If anything I would guess there's a negative correlation.

I guess more politeness in a culture makes it easier to be passive-aggressive, if that's something you want.
