Is abortion and the brith control pill culling intelligence out of the human race?

Farmers selectively breed animals with traits they desire and kill those with traits they don't desire. The human race is selectively reducing those with higher intelligence. Anyone who takes the pill or has an abortion is likely to be of higher intelligence who is doing it to improve their quality of life. G-factor, the speed in which the brain works, is hereditary. The g factor arises from the empirical fact that scores on a large variety of independently designed tests of extremely diverse cognitive abilities all turn out to be positively correlated with one another. The g factor appears to be a biological property of the brain, highly correlated with measures of information-processing efficiency, such as working memory capacity, choice and discrimination reaction times, and perceptual speed. It is highly heritable and has many biological correlates, including brain size, evoked potentials, nerve conduction velocity, and cerebral glucose metabolic rate during cognitive activity.
