The report is taken at face value: the attachment is real, it arrived after the child rather than before, and it is not being dismissed as self-deception. The problem is what it can establish. The claim that the feeling arrives afterwards is unfalsifiable in the present, because counter-evidence can be attributed to not having had the child yet, and it can only be refuted by someone who dies old without having changed their mind. The population making the claim is also selected: the people who changed their minds are visible, and those who did not are underrepresented, their consistency having removed them from the reproductive pool. Parents who made an irreversible decision have a reason to validate it. The biological version, that the feeling will override the philosophy, argues for the antinatalist position rather than against it.
