出生前検査に関する情報提供は障害ある人の生への否定的評価を表出するか

This article investigates two major objections against the expressivist argument in the context of Japan, in probing whether such an argument applies to the governmental or medical professional policy of uniformly presenting information on prenatal testing to all pregnant women. In so doing, the article offers certain recommendations for future governmental or professional medical policies adopted in Japan regarding information provision of prenatal testing. The expressivist argument states that prenatal tests to select against certain disabling features express a negative belief about, or attitude toward existing people who live with such traits. This contention has been theoretically criticized in discrete ways. However, the recent emergence of noninvasive prenatal testing（NIPT）has caused the argument to regain widespread attention and advance remarkably. This article attends to two major objections against the expressivist argument: first, prenatal testing for selective abortion does not, in fact, express negative beliefs; second, the argument commits to reproductive autonomy about abortion in general and thus cannot explain the moral distinction between prenatal testing for selective abortion and other measures to prevent fetus disabilities. This paper examines these critiques in the context of Japan and ultimately demonstrates the following outcomes in congruence with the expressivist argument. First, given the current Japanese system, the public policy of uniformly informing all pregnant women about prenatal testing certainly implies a negative assessment of the lives of those currently living with the same disabilities. Second, a wide range of support systems must evolve for people living with disabilities and their families, and changes must be made to Japan’s abortion laws to avoid the expressivist argument.
