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?
