Define eugenics and discuss Francis Galton's influence in the development of the fundamentally flawed ‘science.'
What will be an ideal response?
Francis Galton proposed that selection should be used to improve the human species. Galton started a new field, which he called eugenics. He claimed that by applying the principle of natural selection, we could improve the intellectual, economic, and social level of humankind through selective breeding. Bypassing legal and ethical considerations, Galton's proposals were simple: People with desirable traits such as leadership and musical ability should be encouraged to have large families, whereas those with undesirable traits such as intellectual disability and physical deformities should be discouraged from reproducing. Galton's reasoning was flawed for several reasons, including his belief that human traits are handed down without any environmental influence. His proposals failed to address another important consideration: Who defines what is a desirable or an undesirable trait?
