King's traits and attributes

[Martok]

So Acumen actually increases happiness? I always thought only dread and piety did (and only the latter for leaders).

Gah! Sorry mate, I wasn't very clear in my post. You were correct before; acumen only increases income, *not* happiness. (I simply talked about acumen & dread in the same paragraph since they work the same way.)

Is it also true that (from my observations) having a low piety governor can be good if few people are of your religion and zeal is low as opposed to the contrary?

Yes, you're correct. If you own a province in which the majority of the people are a different religion than your own, then it's best to install a governor there who has little or no piety.
