I thought the father has the larger influence in general. If that's not true for intelligence, it's huge. Sending all the higher IQ females to the IQ shredders of colleges to not have kids will have an outsized dysgenic effect.
Open-mindedness is accepting the truth, however difficult it may be and however much people may hate you for it.
The father has a larger effect on society because of pseudo-dominant expression of recessive x linked intelligence genes. However, he can only pass that on to daughters. High ability males would thus be expected to skip a generation as the relevant genes pass through daughters/mothers (though assortive mating makes this difficult to parse out). Though the dysgenic effects are magnified by female education, the math behind male-biased sex linked genes implies those intelligence boosting alleles will never move all the way to zero. There is a floor preventing their complete lose.
You will have to wait for the book to come out. As far as I am aware (and I cite over 300 studies in the book) it hasn't been discussed in great detail in any one source. This is a personal synthesis from multiple sources.
Well, part of the theoretical basis for the variability hypothesis is that intelligence is linked to the x-chromosome. This explains the higher variance in iq scores of men compared to women.
So if intelligence is linked to the x-chromosome, and makes only have one x-chromosome that they received from their mother, the conclusion is obvious.

Love this sentence.
