@SarahGen-- That's a good question.
I'm not an expert on this topic so I'm not sure. But since religion is a basis of moral and ethical rules for most societies, I would assume so.
I'm also interested in whether someone can improve moral intelligence just by trying. Can empathy be learned for example?
I know that for example, it is possible for sociopaths who tend to have low levels of moral intelligence to learn to show more inhibition empathy. But does this mean that they have higher levels of moral intelligence or does it just mean that they are pretending to have higher morals?
I think it's very difficult to test this theory. I think that someone who pretends to care or who learns to do something knowing that that's what others consider to be right, may no actually have better morals. But how can we prove either?
