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.

ANCOVA across six age groups with IQ as covariate on CGT risk adjustment. The article reports a "bell shape" across age groups, F(5, 135) = 3.87, p < 0.01, η p2 = 0.13, with the 14-year-old group showing the highest risk-taking tendency, which declined after age 14.
"analysis of CGT risk adjustment showed a bell shape (see Table 11, Figure 6) across the age groups, [ F(5, 135) = 3.87, p < 0.01, η p2 = 0.13]."
