"Why are women dumb?" A rather intelligent little boy, who had become interested in astronomy, asked me this. I asked why he thought that. He said that all of the famous astronomers and scientists were men. I made a note to talk to someone about his history books and lessons, and then tried to answer his question. It is a natural conclusion to have drawn in the face of no evidence of female input in the field of science. It is, beyond that, a valid question.
Submitted for your evaluation, this was my answer.
They are not. They were not taught to read and thusly not allowed to use the expensive equipment until the modern 21st Century. Women were busy doing their part on the domestic side of modern civilization. When that became less labor intensive, fertility became a controlled factor in their lives and they were thusly taught to read and be educated in larger numbers and at higher levels. They immediately demonstrated that their lack of representation was not from a lack of capacity, but a lack of opportunity to compete. Hence, Vera Rubin, a first generation veteran of the modern age of feminism, discovered dark matter in the 1970's.
Don't assume that women were dumb because they are not in the history books. Don't let your young children assume that. Correct them without demonizing men. The distribution of human resources over time was logical as biology dictated our relative roles in the world. That is no longer true and the intellectual capacity of women is easily demonstrated in the work product of women since roughly 1950. Within 20 years of women being allowed to attend universities in the fields of science, a woman discovered the solution to Einstein's mass-energy problem.
Clear this up when you see the natural inference being made by young minds that women are dumb when they see no record of female achievement in the history of science. It was not our intelligence that was lacking, it was the advancement of the hierarchy of needs of civilization that needed to get us past our biology in order to free us up from the servitude of domestic life. It was a necessary step in the evolution of human consciousness and progress.
Don't confuse that with a lack of capacity to compete. Men, who benefited from this arrangement for the whole history of civilization, are beginning to see their power erode in the face of women naturally succeeding in the world of ideas, commerce, and public life. Some men are ok with all that, some men are threatened by that. The ones who are threatened and who would like to preserve the status quo that gives them a natural advantage of power, are trying to destroy our biological advances in contraception. It is a means to turn the clock back to the time when women are enslaved by nature. Let's not have that. Science and the advancement of civilization needs women.
Vera Rubin demonstrated the presence of dark matter while bearing 4 children, having been refused admission to Princeton because of her gender, and while guerilla fighting through the feminist movement of the 1960/70's in the US. She never mentioned the war on women, she just fought it every day and won.
Fight the war on women. What will you say you did when it is finally over?
