  He worries that expanded use of non-invasive first trimester tests may ultimately increase the number of abortions of fetuses with Trisomy 21 and with it, further threaten the wellbeing of people with Down Syndrome. But rather than arguing that people should not selectively abort fetuses with Trisomy 21, pro-choice Kaposy argues for a more capacious understanding of how good life can be and why choosing to continue pregnancy after such a diagnosis is perfectly reasonable. Indeed, if more people chose to have children with Down syndrome this would counter the prevalence of harmful prejudices. His key concern is that much of the impetus to abort following a prenatal diagnosis comes from misinformation, faulty inferences, and biases that people might disavow if they were made aware of them. He offers his book as a way to increase the “social fund of knowledge.”
