eugenics

This term carries a heavy negative connotation in contemporary discourse due to its historical association with forced sterilization, systemic racism, and the atrocities of the Nazi regime. While it describes a field of study, it is rarely used today as a neutral scientific term and is instead typically discussed within the context of ethics, human rights violations, and social engineering.

Grammatically, eugenics is a mass noun that functions as a singular entity despite its -s ending. It follows the pattern of other academic disciplines like mathematics or physics, meaning it takes a singular verb (e.g., "eugenics is") and does not have a plural form.
