A better thought experiment would be to ask whether, if you had a button which would affect the next generation of children (so you do not infringe on the rights of people who already exist) to increase math ability in women but decrease it in men, should you use it to bring the averages in line?

Well, that would make the universe less organized and in particular make it harder to find the people with the best people in math, so likely retard scientific progress somewhat.
