That in 39% of the cases the child was not even theirs! She just took problem dads, not the ones that paid real regular and were OK.
Looks to me like, if the child is not theirs they somehow know or suspect it at some level, and sense it isn't really bonding to them and not their own, and next thing you know they skip paying or are late.
Whereas if it IS their own they will send the money if at all possible, even if the woman hates them and has a court ordered stay-away and has charged them with abuse and all the usual rest of nastiness.
A frightful number of men are paying for other peoples kids, gives one flew over the CUCKOO's nest a whole new meaning, doesn't it?
Other studies show that 5% of all IN wedlock births, the father is not the husband. Milkman, Mailman, etc jokes are too true to be funny any more.
I found this out when I was pregnant! My blood type is Rh-. My husband also has Rh- blood. The Dr STILL wanted to give me a rhogam shot. Just in case. It was his policy.
