>>10146200different neural architecture, humans have the same general cortical structure but at a fine level of analysis higher iq people have less redundancy of connections, and more architectonic complexity, higher white matter mass and larger neocortex than stupid people. Men have larger brain volume, mass and more architectonic complexity, ergo they are more likely to be better at complex cognitively demanding tasks. the catch is that women have a lower rates of low iq people and much lower rates of autism and debilitating behavioral disorders like adhd and compulsive violence, so there are more 110 iq women than men but significantly less 130+ iq women than men. It becomes almost comical above 140 iq where anywhere from 8:1 to even 16:1 male to female ratios are present. Women are very reliable for general competence (lacking imbecilic qualities) but not at all as consistently genius or highly intelligent. this matters considerably for scientific and mathematical achievement. Most importantly other behavioral traits like neuroticism and creativity are higher and lower in women respectively than in men, which is a problem for putting women in charge of political or social institutions, allowing them to teach higher education or to participate in scientific research or high levels of economic activity like finance or building projects. There are other implications, women have higher rates of depression but lower rates of schizophrenia, women have lower levels of sexual compulsivity but are also more detached when making ruthless sexual selection driven decisions than males.
