Jamie Lynn Spears: uncertain paternity?

Turns out that Jamie Lynn Spears' baby daddy is expressing paternity skepticism. He might check out the paper How Well Does Paternity Confidence Match Actual Paternity? Evidence from Worldwide Nonpaternity Rates:

This survey of published estimates of nonpaternity suggests that for men with high paternity confidence, nonpaternity rates are typically 1.7% (if we exclude studies of unknown methodology) to 3.3% (if we include such studies). These figures are substantially lower than the "typical" nonpaternity rate of 10% or higher cited by many researchers, often without substantiation...or the median worldwide nonpaternity rate of 9% reported by Baker and Bellis....

Men who have low paternity confidence and have chosen to challenge their paternity through laboratory testing are much less likely than men with high paternity confidence to be the fathers of their putative children. Although these men presumably have lower paternity confidence than men who do not seek paternity tests, this group is heterogeneous; some men may be virtually certain that the putative child is not theirs, while others may simply have sufficient doubts to warrant testing. Most of these men are in fact the fathers of their putative genetic children; only 29.8% could be excluded as biological fathers of the children in question.
