It's called "knowing yourself"

People who think "I think I will likely be happier with children" will be positively correlated with people who have children and are happy about it.

People who think "Having kids will probably make me less happy, so I won't have any." will be negatively correlated with having children, or being happy about them if they do.

This isn't irrational. It's just knowing yourself and choosing wisely.
