Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i1 The pooled gV effect significantly favours males (d = 0.21), equivalent to about 3.09 IQ points. → D. Giofrè · K. Allen · E. Toffalini · S. Caviola 2022
q3 i? The old/new battery version was not a significant moderator of the gV effect. → D. Giofrè · K. Allen · E. Toffalini · S. Caviola 2022 (2)

q3 · i1 · quant-synthesis · r3
Meta-analysis of 26 studies (39 samples) for the gV factor; all gV subtests showed effects close to d ≈ 0.20 favouring males, and the standardization-sample estimate was similar (d = 0.17).
"The estimated mean effect size was significant but small, with higher scores in males than in females, d = 0.21 [0.16, 0.25], p < 0.001."

q3 · i? · quant-synthesis · r3
Meta-regression moderator test on the gV factor; the article notes Block design in particular showed a male advantage that seems large and relatively unchanged between WISC versions.
"The old/new version of the battery did not appear to be a moderator of the effect size, χ2(1) = 0.55, p = 0.46, Δd = 0.04."
Discussion¶
Related Claims¶
- Gender differences on WISC subtests and factors are generally smaller or unchanged with newer WISC versions, never larger — related
- Females outperform males on WISC processing speed (gS) with a medium advantage (d = -0.37), larger for Coding than Symbol search — related
