I just tried it the other way. I took my planets down to riot stage and then left them alone. They shortly increased back up to indifferent ( with no pac center, troop or vacation) by themsleves. So it appears that natural decrease does work both ways to move toward indifferent status. Now I will have to see what other race does happiness does since it is a postive number instead of a negative. Also I might look at what a postive number in natural decrease does. A positive number may mean that your race goes faster to riot or jubliant when then get away from beign indifferent.

colonization with another race works as expected. They lost happiness all the way down into rioting stage.
A positive number in happiness increase for you race did send the happy race into jubilant. I did not test but I assume that under the same a unhappy race would then go to rioting.

So a negative number in natural decrease for race sends you to indifferent. A positive number sends you futher away from indifferent.
