It's quite fun to imagine doing research on this. You could stand around outside a primary school with a clipboard at the end of the day and ask fathers whether they believe they are the biological parent of the child and fill in a form that looks like this:
[ ] Man with parental responsibity told me to fuck off.
[ ] Man with parental responsibity said: "Look at him, what do you fucking think?"
[ ] Man with parental responsibity told me it was none of my fucking business.
[ ] Man with parental responsibity punched me on the nose.
[ ] Other.
Then you could correlate that with the genetic data ...
Higher rates might be mythical. In any case, it's unclear what the definition should be. See https://en.wikipedia.org/wiki/Non-paternity_event#Rates_of_n...
