    It’s not definitively HIM until they test him specifically

    That’s my point. They haven’t identified him, the company said she matched some of his relatives. However, it’s quite possible that she also matched some unrelated people, i.e. this is a false positive.

    This is closely related to the “prosecutor’s fallacy”. If the doctor had only a one in a million probability of matching her DNA, most people would consider this conclusive evidence that he is the father. In reality, there are over 300 individuals in the US who would also match, so absent other evidence there is less than a 1 in 300 probability that he is the father.
