There was a test that did show some differences between male & female brains but it ironically proved several gender stereotypes correct so the LGBTQ+ buried it. Effectively the main three differences between Male & FemBrains were amount/quality of neural pathways/transmitters, cognitive response times, and neuroplasticity.
Women have more neural pathways & transmitters than men but they're thinner and more prone to overflow of bioelectricity. The upside is that women do have a slight advantage on mental response times than men but at the expense of easier burnout and overloaded synapses which lead to headaches, migraines, emotional hysteria/mental illness, etc. It also showed that females have more neuroplasticity at child/toddler ages comparatively to men but solidify faster than men in adolescence. While this lead credence that women mature faster than boys, it also means that women become more stubborn and set in their ways than men because their brains solidify earlier.
The reason we're seeing a lot of women act like entitled children is not just social/economic conditioning, it was shown that women's brains take their snapshot at 13-16 while boys take they'res at 18-21 on average. The female brain in a rush to grow up locks itself down with a literal 13-year old girl on the internet imprint that the woman will act upon for the rest of their lives while a man gets locked in based of their late high school to early college years (for better or worse).>TL;DR
The difference between male & female brains proves more stereotypes than breaks them. Women's brains are glass cannons that can process info slightly faster than men but burnout and become prone to bugs such as emotional immaturity and mental illness more than men. Also because of the rapid neuroplasticity solidification for women, they get trapped in a variation of their 13-year old self that slowly rears it's ugly head in the future.
