Ah, ok, I see that now. It's sort of a weird system, really. I think that the attraction percentage might be taking into account the ethics of my synth slaves, but as they don't vote, they don't contribute to faction support. It's frustrating, because the materialist faction only has twenty members and 12% faction support, despite 22% of the population embracing materialism. The damn spiritualist faction has the same faction support, despite only being about 8% of the population! Even more frustrating is the fact that the egalitarian and xenophile factions dislike synth slavery and no longer grant me influence, but I can't actually do anything to change the policy until I can embrace the materialists!
