Women are better parents than men

[Pavo13]

Some men can be better parents than women, some women can be better parents than men. The thing is that it's usually women who are expected to take care of children, they usually have and get full custody (for a bunch of reasons, not because courts favor evil women) and there are far more single mothers than single fathers. So my guess is that there are more good mothers than fathers just because there are more involved mothers in general.
