Credit and blame are the two things anyone leading a group can actually hand out. Pushing credit outward and keeping blame in costs you almost nothing real and buys an enormous amount of goodwill, because most people have only seen the opposite. It also makes the group safer, since nobody is braced to be named. The effect lasts long after the particular game is over.
