In general I suppose it is bad if people can't be honest with their feelings. As one extreme example, I think post-pregnancy depression is actually quite common and can even drive mothers to suicide. Since they can not talk about it because they are supposed to be happy, they often don't get proper treatment. As for helping people evaluate, that seems tricky. How could you simulate the experience of having kids? I guess most people just extrapolate from what they see around them and what they experienced in their own families. And on the case of unwanted pregnancies it wouldn't help anyway.
