Subclaims¶

q2 i? The post hoc Johnson–Neyman findings suggest that fostering trait self-control may not benefit all students equally, since only students above the very low end of the fluid reasoning spectrum profited significantly for grades. → Schmidt FTC 2020

q2 · i? · associational · r3

Authors' interpretation of the post hoc Johnson–Neyman analysis in the Discussion; they write that "These findings to a degree question the usefulness of efforts to foster trait self-control in students in need", implying unequal benefit across fluid reasoning levels.

"These findings to a degree question the usefulness of efforts to foster trait self-control in students in need as suggested by the policy decisions named earlier"

• Trait self-control is significantly associated with major GPA beyond fluid reasoning and conscientiousness in vocational trainees — related
• Trait self-control and conscientiousness overlap substantially, and conscientiousness slightly outperforms self-control for grades — related
