>Roughly 30% of children given paternity tests or even those who use ancestry services discover their assumed fathers... aren't.

Not true in modern contexts. Misattribution of paternity is much closer to 1-2%: https://pubmed.ncbi.nlm.nih.gov/34288189/, https://www.researchgate.net/publication/237633127_How_Well_...

The 30% figure comes from men who already doubt paternity...obviously some strong selection effects there.

In addition, there are very strong cohort effects for divorce. For example, if you have a bachelors the divorce rate is more like 25%.
