I think its more along the lines of what would affect morale, than what morale affects.
So like, your saying that depending on what colony you are, doing certain research and making certain buildings will raise or lower morale?
I dunno, it seems like that would be covered under the simple fact that certain colonies are capable of researching certain things, like Plymouth can't have their morale lowered by researching Eden technologies, because they can't research them in the first place.
