The public is firmly — overwhelmingly — opposed to using gene editing for heritable “enhancement” purposes. Many people, if pressed, will support the concept of heritable “cures” that for the foreseeable future, at least, are not practical and rarely needed, if at all. It is not clear, however, how many of the public (and perhaps the pollsters) have an adequate grasp of the issues involved in heritable human genetic modification (HGM).
CGS has for a decade been collecting polling data going back to 1986: over 50 polls, some of them international, on HGM and/or human cloning are summarized here. Assessing that data, however, has always been tricky.
Polls tend to show that public sentiment about human biotechnologies is strongly ambivalent. Most people value their potential to alleviate suffering, yet are apprehensive about the social consequences of some applications. Public opinion on HGM is particularly difficult to assess because of the ambiguity of some of the questions and the terminology used. Opposition decreases with increased emphasis on cures, and increases with emphasis on non-medical or “enhancement” uses, such as improving intelligence.
Interpreting the data is now of much more than academic interest. Many scientists and policymakers have begun looking for a “broad societal consensus” to guide decision-making about the limits that should be put in place for human genetic applications.
Prompted by this, Robert Blendon, Mary Gorski and John Benson published a survey article, “The Public and the Gene-Editing Revolution” in the New England Journal of Medicine on April 14th. It analyzes, and links, 17 U.S.
