How many % of children are not their own?

[sosumba]

I was listening to a popular program in my country where you can ask a bunch of professors a question and it was asked "how many % of men had another mans child that they thought were their own?". Then this evolutionary biologist says that it was about 99% of children in the west that had the right father. Some years ago this number was 6% in lower-class families while its was 0.4% in middle and upper-class.

I expected this number to be much higher since I have heard other numbers being around here reaching about 20% so I am very interested to get to the bottom of this once and for all.

Do you guys have any studies or sources I can look into?

i talk to a girl who have urinated on a guy in the shower and get them to finger their ****s. so that has 0% chance of him being the father.
she has no kids at 38. makes sense.

IDK, but I'd say somewhere between 10 - 15% worldwide.
