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.
q3 i? Kruskal-Wallis H tests found no statistically significant differences in helpfulness ratings across the four explanation-sequence groups, although the DD group reported the highest mean perceived helpfulness (3.68). → Seth Bernstein 2026

q3 · i? · causal · r2
Likert-scale helpfulness ratings (1 = Strongly Disagree to 5 = Strongly Agree), aggregated without differentiating by snippet, analyzed with Kruskal-Wallis H tests; the test found "no statistically significant differences in helpfulness ratings across groups." Mean helpfulness was highest for DD (3.68) and lowest for DG (3.50).
"A Kruskal-Wallis H test found no statistically significant differences in helpfulness ratings across groups, 𝐻( 7)= 4.42,𝑝=. 730."
