Is there a scientific explanation for the testimony of two women and one man, and what are the sources of research that clarify the physiological characteristics of brain performance and memory in women compared to men?

Scientific research and studies affirm the physiological and functional differences between the male and female brains, which supports the notion of women's intellectual deficit mentioned in the Quran and Sunnah. The male brain has 16% more neurons and weighs 150 grams more than the female brain, and there is a correlation between intelligence and the number of cells. Furthermore, a 1995 study by the University of Chicago, which included examinations of the U.S. Army, showed that there are real differences in how the brain functions, and that the number of men at the lowest and highest ends of the intelligence spectrum is greater than that of women, meaning that the range of male intelligence is wider. Men excel in mathematics and sciences, while women excel in verbal skills, which explains why the number of men in the scientific elite in America is seven times that of women.
