A speculative and highly controversial concept referring to the application of eugenic principles to neuroscience—the idea of selecting, engineering, or enhancing neural traits to produce "desirable" cognitive, emotional, or behavioral characteristics. Neuroeugenics encompasses hypothetical technologies ranging from genetic selection for intelligence to neural engineering for emotional regulation to cognitive enhancement for social conformity. The term carries the historical weight of eugenics movements that justified forced sterilization, racial hierarchy, and genocide under the banner of "improving the human stock." Critics argue that neuroeugenics repeats the same dangerous logic: identifying certain neural traits as "superior," treating human variation as pathology, and justifying intervention on populations deemed "deficient." The concept serves as a warning about where cognitive enhancement technologies might lead when combined with ableism, racism, and the drive for social control.
