IQ variance drives sexed politics

Political coalitions can be shaped not just by mean differences between groups but by differences in variance; higher male variance in measured cognitive ability produces more male representation at both intellectual extremes, which interacts with sexed social preferences to produce asymmetric party profiles (a centrist, ‘midwit’ female-leaning left and a more ideologically mixed male-leaning right). This is an argument about distributional effects (variance), not only averages, and how they translate into institutional composition and messaging. — If persuasive, this reframes debates about polarization, candidate selection, and outreach by focusing attention on distributional sex differences as a structural driver of partisan realignment.
