Women in polygamous marriages tend to have low self-esteem, less satisfaction, and more mental health problems than women in monogamous marriages. Studies find higher levels of depression, hostility and psychological problems in polygamous marriages. “First Wife Syndrome”, so common as to have that name, show that first wives have even lower self-esteem, more anxiety, more paranoia, and more psychotic tendencies than second and third wives.
Naturally, polygamous nations deny all this. What they really deny is that women’s happiness is important.
What are polygamy’s effects on IQ? Everyone in a polygamous home lives in fear of the father. “I divorce you.” repeated three times has them out on the street with no marital assets. That leaves their children in a hostile home, with no defenses against the other children and their mothers.
That’s why children and their mothers in polygamous families fawn over dad. His mistakes are ignored and he is endlessly glorified. There is no balance. Wives, sons, and daughters smart enough to threaten their father are sent away.
If there are ten polygamous families in a neighborhood, there may twenty to forty wives, fifty or a hundred children and ten fathers who own and run everything.
High IQ mothers are most likely to complain and be evicted, penniless. Their smarter children become objects of hostility and are gradually eliminated. The gene pool is leveled. There are few geniuses like Thomas Edison because polygamy lowers IQ.
One polygamous leader recently complained, “The problem with young Moslem men is that they cannot make anything. They like to drive around in automobiles, but they cannot make those automobiles. They cannot even make any of the parts of the automobiles. They cannot even make the nails that hold them together.”
Soon, polygamy produces a people that are most fit for owning slaves and killing any who stand in their way. Their religious and political structures reflect that reality. No advancements like light bulbs, antibiotics, trains, planes, plastics, running water, or submarines originate with them.
The institutionalized, loveless brutality that is polygamy lowers IQ, personally and within the culture. That makes higher level thinking impossible.
