Eugenics is the belief and practice of improving the genetic quality of the human population. Eugenic efforts can be carried out voluntarily, through a process of sexual selection in which people attempt to choose mates with the best genes, or involuntarily through statist aggression in which the politically powerful attempt to impose their vision of what should be the genetic makeup of society. Not all human behavior results from genetics, so achieving optimal outcomes also requires eumemics. Some proponents of eugenics included Margaret Sanger, founder of Planned Parenthood, Sidney Webb, George Bernard Shaw, T.S. Eliot, D.H. Lawrence and economist Irving Fisher.
The ideology which advocates the use of reproductive and genetic technologies where the choice of enhancing human characteristics and capacities is left to the individual preferences of parents acting as consumers, rather than the public health policies of the state, is known as liberal eugenics.
