G-BASED GENDER IQ FINDINGS (SOLID, RELEVANT LITERATURE ONLY)
1) OVERALL PATTERN
• Boys and girls score essentially the same on g throughout childhood.
• After puberty, adult men show a small positive shift in mean g.
• The observed shift is consistently reported at ~+4 to ~+6 IQ points, depending on test battery.
• Variance is comparable between sexes; the claim that men have systematically larger deviation is not supported by the data.
2) KEY RESEARCH
Jensen & Reynolds (1983) — WISC-R (children)
• No meaningful gender gap prior to adolescence.
• No evidence of a sex difference in variance in childhood samples.
Lynn & Irwing (2004) — Meta-analysis (~57 samples; Raven’s, etc.)
• Adult male mean advantage on g ≈ +5 IQ points.
• No consistent evidence for greater male variance; variance differences are small, inconsistent, or absent across samples.
• Difference emerges post-adolescence.
Hyde (2005)
• Small male advantage in spatial and reasoning components.
• Negligible difference in verbal ability.
• No reliable evidence for a general male-variance effect on g.
Colom et al. (2003)
• Male advantage in variable reduction and spatial reasoning.
• Findings do not rely on, nor require, a greater-male-variance hypothesis.
3) DISTRIBUTION CONSEQUENCES
(Mean difference ≈ 5 IQ points; SD ≈ 15)
• IQ >130 → ~2 men per 1 woman
• IQ >145 → ~3–4 men per 1 woman
• IQ <70 → 2 women per 1 man
These ratios follow directly from normal-distribution mathematics given the stated parameters, without invoking greater male variance.
4) BASIS
• Replicated across decades.
• Replicated with different instruments.
• Observed across cultures.
• Consistent with developmental neurobiology.
most ppl think men are just physically superior
no we are superior in all ways except like nurturing babies,in that field they mog us brutally
