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 i? The cognitive skills shared large amounts of genetic variance, as did the reading-related skills. → Christopher 2016

Hierarchical models found that "the cognitive skills also shared large amounts of genetic variance, as did the reading-related skills".
"The cognitive skills also shared large amounts of genetic variance, as did the reading-related skills."
Discussion¶
Related Claims¶
- Full-scale IQ is genetically related but not redundant with common cognitive variance — related
- Common cognitive genetic variance is highly correlated with common reading genetic variance — related
- Genetic influences drive the phenotypic correlations between cognitive skills and reading components — related
- Skill-specific genetic variance in working memory and processing speed predicts reading components — a narrower finding that bears on this claim
- Reading comprehension variance is fully shared with listening comprehension and word reading — related
