ULTRASOUND VIEWERS' ATTRIBUTION OF MORAL STATUS TO FETAL HUMANS: A CASE FOR PRESUMPTIVE RATIONALITY

As several studies, along with a book and movie depicting the true story of a former clinic director, have recently brought to the public's attention, fetal ultrasound images dramatically impact some viewers' normative judgments: a small but non-negligible proportion of viewers attribute increased moral status to fetal humans and even form the belief that abortion is impermissible. I consider three types of psychological explanation for a viewer's shift in beliefs: (1) increased bonding or empathy, (2) various forms of cognitive bias, and (3) type of cognitive processing involved. I consider the normative implications of each explanation, arguing that in each case the viewer's judgment is presumptively rational.
