Euthenics

Euthenics (/juːˈθɛnɪks/) is the study of improvement of human functioning and well-being by improvement of living conditions.^[1] "Improvement" is conducted by altering external factors such as education and the controllable environments, including environmentalism, education regarding employment, home economics, sanitation, and housing, as well as the prevention and removal of contagious disease and parasites.^{[citation needed]}

In a New York Times article of May 23, 1926, Rose Field notes of the description, "the simplest [is] efficient living".^[2] It is also described as a right to environment.^[3]

The Flynn effect has been often cited as an example of euthenics. Another example is the steady increase in body size in industrialized countries since the beginning of the 20th century.

Euthenics is not normally interpreted to have anything to do with changing the composition of the human gene pool by definition, although everything that affects society has some effect on who reproduces and who does not.^[4]
