What does a parent owe their child?
Summary
Sean Illing introduces a Vox Unexplainable episode where host Noam Hassenfeld and reporter Seagal Samuel debate the ethics of genetic embryo screening. They explore whether parents have a moral obligation to optimize their children’s health and traits, weighing the desire to prevent disease against risks of eugenics, social inequality, and implicit coercion. The discussion highlights the complexity of polygenic testing and advocates for a "good enough" approach rather than maximizing every variable.
