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? Claim, data and warrant, and rebuttal claim showed no significant differences across conditions. → Chang 2026 q2 i? Organisation, clarity, relevance, and persuasiveness showed no significant differences across conditions. → Chang 2026 (2)

q2 · i? · causal · r2

Kruskal-Wallis H tests of structural-complexity element gains across the three conditions. Claim, data and warrant, and rebuttal claim were non-significant; data and warrant was marginal (p = 0.057). Equivalence was not tested.

"the three groups did not differ significantly in the other three elements of structural complexity: claim (H = 1.04, p = 0.596, ε2 =-0.02), data and warrant (H = 5.74, p = 0.057, ε2 = 0.08), and rebuttal claim (H = 4.20, p = 0.123, ε2 = 0.05)."

q2 · i? · causal · r1

Kruskal-Wallis H tests of argument-quality dimension gains across the three conditions. Organisation, clarity, relevance, and persuasiveness were non-significant; clarity was marginal (p = 0.056).

"the three groups did not differ significantly in the other four elements of argument quality: organization (H = 3.02, p = 0.221, ε2 = 0.02), clarity (X2 = 5. 77, p = 0.056, ε2 = 0.08), relevance (X2 = 1.96, p = 0.376, ε2 = 0.00), and persuasiveness (X2 = 0.51, p = 0.775, ε2 = 0.00)."
