Eugenics is the self-direction of human evolution. It is the study of hereditary improvement of the human species by
selective breeding. It is both a science and a social movement. The idea is to increase the number of children of those with favorable genes (such as
intelligence, good health, positive personality traits, good looks, etc..) and limit the number of children of those who have unfavorable genes (such as poor health, lower IQ's, mental flaws such as anti-social
personality disorder, and physical defects) thus improving humanity's lot.
People often do not understand there is a different between positive eugenics and negitive eugenics. An example of negitive eugenics is forcible sterilization of people with mental or physical defects. An example of positive eugenics is encouraging those with good genes to have more children.
There is nothing wrong or evil with wanting to improve humankind. Eugenics is widely practiced by
those who breed animals in order to produce healthier, more even
tempered, better looking animals, why not on humans?
