Headline Findings
The current headline layer contains 67 confirmatory cells across 17 live datasets. Here, confirmatory means the pre-designated core trait rows used for the main headline claim, not the secondary or exploratory rows. Male-greater variability appears in 85%, while the strongest counterexample remains visible rather than being averaged away.
The strongest male-greater confirmatory cell is Numeracy in PIAAC cycle 2, age 60-65, with VR 1.46x.
Reading achievement in ECLS-K:2011, Fall Kindergarten 2010, age K, shows VR 0.10x with 95% CI 0.10x to 0.10x. The public summary keeps this reversal explicit.
Headline Forest Plot
Each point is a headline-eligible confirmatory cell, meaning a core pre-designated row that is allowed into the main claim, with whiskers on the variance-ratio scale.
Dataset-Trait Medians
Median variance ratios by dataset-family combination show the distribution without relying only on the most extreme rows.
