Dysgenics refers to any decrease in the prevalence of traits deemed to be either socially desirable or generally adaptive to their environment due to selective pressure disfavouring their reproduction. In 1915 the term was used by David Starr Jordan to describe the supposed deleterious effects of modern warfare on group-level genetic fitness because of its tendency to kill physically healthy men while preserving the disabled at home.
