Feminism leads to women choosing the wrong lovers/ husbands.... I believe that this effect will cause the average IQ of the feminist inspired countries to decrease.

How does staying at home provide an environment for intellectual stimulation
|
Perhaps it does not. In the United States of the 20th century, parental
g, combined with ancestral
g, has been found to be the single most powerful predictor of offspring
g. Experimental variance in intellectual stimulation has so far been inconclusive with respect to variance in
g.

The Milwaukee Project. Aside from Head Start, this is the most highly publicized of all intervention experiments. It was the most intensive and extensive educational intervention ever conducted for which the final results have been published. 55 It was also the most costly single experiment in the history of psychology and education--over $14 million. In terms of the highest peak of IQ gains for the seventeen children in the treatment condition (before the gains began to vanish), the cost was an estimated $23,000 per IQ point per child....
The study sample was divided into fairly equivalent treatment (T) and control (C) groups, each with twenty infants....
The T group, despite having a ten-point higher IQ than the C group, still performed in school very much like the C group. That is, both the T and C groups performed in school much as would be expected for children with an average IQ of eighty. The evident lack of generality, or broad transfer, of the effects of the T group's previous cognitive treatment indicates that the T-C gain in IQ was "hollow" with respect to g.

As far as a home environment possibly providing
cognitive stimulation, electric lighting, as it is known to affect the pituitary gland, may affect brain growth:
The increased hours of exposure to electric lighting and television are also probably responsible for some part of the increased overall rate of maturation, via stimulation of the pineal gland--an effect that has been demonstrated experimentally in animals. 31 - 31. Modern mass-production poultry farms make use of this phenomenon, by keeping chicks under bright electric lighting twenty-four hours a day, to hasten their rate of growth and the time needed to reach their maximum egg-laying capacity.
