Lack of eugenic measures

Lack of eugenics
Insufficient intervention in human evolution
Discrimination against eugenics
Active prejudice towards selective breeding of humans

Nature

In the absence of eugenic measures, persons suffering serious hereditary diseases, with a high risk of transmitting them to their children, are not discouraged from having children.

Incidence

Globally, the incidence of lack of eugenic measures varies widely, with most countries not implementing formal eugenic policies due to ethical, legal, and human rights concerns. According to a 2017 review in the *Journal of Community Genetics*, only a minority of nations have state-sponsored genetic screening or counseling programs, and these are typically voluntary and focused on specific conditions rather than broad eugenic aims.
A notable example occurred in India in 2016, where the absence of systematic genetic counseling and screening contributed to a high prevalence of thalassemia births, particularly in Gujarat, as reported by the Indian Journal of Hematology and Blood Transfusion.

Claim

Genetic counselling procedures would not be effective in the case of persons suffering from high-grade mental retardation which is of special importance due to its frequency, and some form of enforcement may be required.

Counter-claim

Eugenic measures will never cause hereditary diseases or disabilities to disappear completely. Spontaneous mutations, the coming together of heterozygous carriers of recessive conditions, and other factors will always bring about new cases.
