How did genetic screening raise concerns connected to the idea of “new eugenics”?

The concept of "new eugenics" refers to modern applications of medical genetics that, while often focused on reducing hereditary disorders, mirror historical eugenic aims of identifying and eliminating "undesirable" genetic material.1

Genetic screening and related technologies, such as preimplantation genetic diagnosis, raise significant ethical concerns:

• Devaluation of Disability: Critics argue that societal investment in screening sends a message that disability is a "medical tragedy" to be prevented at all costs, potentially devaluing the lives of disabled individuals.2
• Reproductive Selection: The ability to screen embryos or terminate pregnancies involving genetic disabilities is viewed by some as a form of genetic selection, which may lead to the elimination of individuals with specific conditions.13
• Social and Ethical Risks: Concerns include the potential for genetic discrimination by employers or insurers, issues of privacy, and the risk that these technologies could be used for non-medical traits, such as sex selection.435
• Nondirective Counseling: There is ongoing debate regarding whether genetic counselors can truly remain nondirective, as the language used to describe "risk" and "abnormality" inherently influences patient decision-making.2

While these tools offer the potential to alleviate suffering, they must be managed with a firm commitment to human dignity, ensuring that the pursuit of health does not become a tool for prejudice or the marginalization of those with genetic differences.126
