American eugenicists wanted to prevent people with bad traits from having children. Some argued for institutionalizing the feebleminded to stop them from having sex. Some called for sterilization.

It would be pointless to try to improve these people through experience, because, McKim declared, "heredity is the fundamental cause of human wretchedness.
