It has generally been accepted that positive eugenics
is not enough to significantly improve the genetics of the human race, therefore negative eugenics were also required.
At this time, the Eugenics Society was leaning towards negative eugenics, believing it to have a more immediate effect on stemming the differential fertility rate than positive eugenics
(Soloway, 1995: 640; Thomson: 201).
Thus neither the truth claims of the positive eugenics

It is possible that additional historical documents may support a parallel emphasis on positive eugenics
in the province.
Public education and voluntary abstinence were considered positive eugenics
According to Habermas, "the procedures of preimplantation genetic diagnosis and research on human embryonic stem cells demand the adoption of wide-working attitudes that tend to promote the transition from a negative to a positive eugenics
," that is, from practices concerned with preventing the transmission of severely disabling conditions to practices aimed at optimizing a child's genetic makeup (158/96).
8) Positive eugenics
too has received scholarly attention, with examination of particular attempts to educate people about Mendelian laws of inheritance through such things as "Fitter Families" and "Better Babies" contests at state fairs in the 1920s and 30s.
He supported negative eugenics but recognized a more cautious approach to positive eugenics
as means for social development.
While Wells consistently rejected positive eugenics
, claiming that the creation of an ideal type was antithetical to the principles of Darwinian evolution and arguing that competitive selection was a prerequisite for species advance, he felt that negative eugenics--the prevention of "congenital invalids" and certain anti-social types from breeding and the employment of euthanasia against severely "diseased" new-borns--did have a role in a scientifically-organised society.
To conduct research on positive eugenics
, West German and Danish fertility rates, and to measure genetic distances between major races .
Policies within the eugenics movements in the early decades of the 20th century included positive eugenics
, which sought to foster more breeding among those deemed to be socially meritorious; and negative eugenics, which sought to discourage breeding among those deemed to be socially disadvantageous.
encouraged individuals who were above average both mentally and physically to produce more offspring.
is similar to Plato's view which attempts to improve the race through selection and maximization of "socially desirable" genes.
Important distinctions between population and individual eugenics and between negative and positive eugenics
are glossed over, and the account of the purposes of medicine from which a principled distinction between preventing disease and creating superior children would follow is left undeveloped.
