Simpson’s paradox. The causal axis is (more strongly) positive for career success, but the informative axis is negative for the choice to pursue economic mobility through a career versus family. In simple terms, more attractive women are more likely to marry rich and neglect career success, while the number of men that pursue this strategy is much lower.

Reminder that statistics are only accurate for exactly the question asked. We have a bad habit of assuming that we correctly asked the question that we are actually interested in.
