I currently 'have' a minor SF setting, for which there exists a few short stories, comics, pictures, and the like, created by a variety of artists and authours. I'd like future contributions to be as rationalist as possible - for as many characters within the setting as possible to be Rationalist!Heroes, or even Rationalist!Villains. Do you have any advice that might help me try to nudge the various amateur artists and authours involved in that direction?
(In case you're curious, the setting's current reftext is here. The basic underlying question I'm basing it around is, "As technology advances, it becomes possible for smaller and smaller groups to kill more and more people. How can society survive, let alone develop, when individuals have the power to kill billions?" So far, most of the creations have been developing the overall background and characters, rather than focusing on that question directly.)
