Should We Use Genetic Technology to Boost Human Intelligence?

Chinese researcher He Jiankui is now world-famous for having announced the creation of genetically-modified twins that would be resistant to HIV. He said that he edited the genomes of these twins with CRISPR/Cas9, a technology that makes it possible to target specific genes within a living organism. Everywhere, scientists and non-scientists alike reacted with astonishment. Most comments were negative, but not all were critical of gene editing per se. Julian Savulescu, the Uehiro Professor of Practical Ethics at Oxford who favors gene editing and embryo selection, released a press statement denouncing Jiankui’s decision to perform the experiment on healthy babies instead of on embryos that had fatal genetic diseases and would be certain to die in the absence of the intervention. He also pointed out that gene editing is still experimental and “capable of causing genetic problems early and later in life, including the development of cancer.” By contrast, Marcy Darnovsky, the Executive Director of the Center for Genetics and Society and a long standing critic of genetic editing, wrote: “In a time of resurgent …
