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.

q2 i2 In the I/E model, effects of achievements on self-concepts within subjects represent not only social comparison effects but the difference between positive social and negative dimensional comparison effects; reinterpreting Möller et al.'s (2020) meta-analytic betas yields social comparison effects of about β = .36 in the math domain. → Fabian Wolff · Jens Möller 2022

Analytical argument (with an algebraic rearrangement of the I/E regression equation) showing the within-subject path equals W + B, so social and dimensional influences are confounded. The article derives that prior meta-analytic social effects were "about β = .36 (= .55–.19) in the math domain".

"in the I/E model, the effects of achievements on self-concepts within subjects represent not only effects of social comparisons but also the difference between (positive) social comparison effects and (negative) dimensional comparison effects"
