However, the issue refuses to be buried. More recently, Herrnstein and Murray (1994) in The Bell Curve, argue that poor inner-city communities are a ‘cognitive underclass’ formed by the interbreeding of people with low IQ. The dearth of people with training in the science of psychometrics now hinders any serious attempt to counter these arguments. Today, the major counterarguments against the bell-curve hypothesis and the latter-day eugenicists are based on the Flynn effect (Flynn 1984). The Flynn effect is the name used to describe the now well-documented year-by-year rise in IQ scores that dates back to the early 20th century when the practice of IQ testing first began.

A population is said to be degenerating (dysgenic) if it exhibits either enhanced reproduction levels among organisms with seemingly undesirable characteristics, or if it exhibits diminished reproduction among organisms with seemingly desirable characteristics. Eugenicists argue that we humans, by caring for the sick and ‘unfit’, are undergoing dysgenic degeneration, and that scientists should become involved in damage limitation. Partly, this means that we should improve the ‘quality’ of the human population by selective breeding.
