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 i? The simple slope of trait self-control on mGPA was significantly positive among individuals scoring higher than −1.5 SD below average on fluid reasoning; no such regions emerged for mathematics or physics. → Schmidt FTC 2020

Schmidt FTC 2020¶
Schmidt FTC, Lindner C, Etzel JM and Retelsdorf J (2020) Self-Control Outdoes Fluid Reasoning in Explaining Vocational and Academic Performance—But Does It? Front. Psychol. 11:757. https://doi.org/10.3389/fpsyg.2020.00757
q2 · i? · associational · r3
Post hoc Johnson–Neyman probing of the non-significant interaction (Figures 1–3); the analysis found the TSC–mGPA association "significantly positive among individuals scoring higher than −1.5 SD below average on the fluid reasoning measure", with no such regions for the tests.
"The Johnson–Neyman procedure revealed that the association of trait self-control with mGPA was significantly positive among individuals scoring higher than −1.5 SD below average on the fluid reasoning measure"
Discussion¶
Related Claims¶
- Fluid reasoning, not trait self-control, predicts low-stakes standardized mathematics and physics test scores — related
- Trait self-control is significantly associated with major GPA beyond fluid reasoning and conscientiousness in vocational trainees — related
- Post hoc findings question whether all students benefit equally from efforts to foster trait self-control — possibly the same claim (merge candidate)
- Trait self-control correlates with grades but not with standardized test scores at the bivariate level — related
- No significant trait self-control × fluid reasoning interaction effects on grades or standardized test scores — related
- Trait self-control and conscientiousness overlap substantially, and conscientiousness slightly outperforms self-control for grades — related
