Each pop in an empire will embrace a single, moderate ethic, which determines the Faction a pop will eventually join. At the start of the game the population's ethics will match the empire ethics but as an empire grows its population will become more diverse in its views and wants. Each ethic has an attraction value for each pop in an empire depending on both the empire's situation and their own situation.

Over time, the ethics of the pops will drift in such a way that it roughly matches the overall attraction of that value. For example, if the materialist attraction sits at 10% for decades, it's likely that after that time, around 10% of all pops will be materialist. There is some random factor so it's likely never going to match up perfectly, but the system is built to try and go towards the mean, so the more over-represented an ethic is compared to its attraction, the more likely pops are to drift away from it and vice versa.

The following attraction factors are valid for each ethic:
* {{green|+2}} if the empire has the ethic in moderate form
* {{green|+3}} if the empire has the ethic in fanatic form
* {{green|+2}} if the empire does not have the ethic and the Faction representing it has formed
* {{green|+0.5}} if the leader of the Faction representing the ethic is the empire ruler

Each ethic has its own multitude of factors that will increase or lower its attraction.
