Dysgenics
Dysgenics is the decrease in prevalence of traits deemed to be either socially desirable or well adapted to their environment due to selective pressure disfavoring the reproduction of those traits.[1]
The adjective "dysgenic" is the antonym of "
Dysgenics: Genetic Deterioration in Modern Populations, which argued that a reduction in selection pressures and decreased infant mortality since the Industrial Revolution have resulted in an increased propagation of deleterious traits and genetic disorders.[5][6]
Despite these concerns, genetic studies have shown no evidence for dysgenic effects in human populations.[5][7][8][9]

There is no convincing evidence that any dysgenic trend exists. . . . It turns out, counterintuitively,[clarification needed
