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? Fatigue-substances such as carbon dioxid and lactic acid, when present in small quantity, increase protoplasmic activity and augment muscular energy, which Lee uses to explain the Treppe. → G. M. W 1910

q2 · i? · review · r2
The review reports Lee's experimental finding, as summarized in his Popular Science Monthly address, that "when present in small quantity" the fatigue-substances increase activity; no effect size or sample details are printed.
"Lee has found by experiment that these substances, when present in small quantity, increase protoplasmic activity and augment muscular energy."
Discussion¶
Related Claims¶
- Effort's relation to achievement differs by operationalization: quality-of-learning effort shows a positive link, quantity-of-learning effort is weak, conditional, or negative — related
- Lee argues the brain and spinal cord show a high degree of resistance to fatigue, with no indisputable evidence of genuine nervous-system fatigue — related
