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? PsyScore-AES ranks first on 10 of 11 trait dimensions with mean QWK 0.735, including a Voice improvement from 0.619 (ArTS) to 0.740, though it trails T-MES on Style (0.683 vs 0.721). → Wei Xia 2026

q2 · i? · design · r2
Trait-level comparison in Table 2 of the ASAP++ evaluation: the model leads "10 out of 11 evaluated dimensions" with mean QWK 0.735; Voice rises from 0.619 to 0.740, while Style trails T-MES (0.683 vs 0.721).
"At the trait level, PsyScore-AES ranks first in 10 out of 11 evaluated dimensions, achieving a mean QWK of 0.735. In the Voice dimension, which is typically more subjective, the model improves the QWK from 0.619 (ArTS) to 0.740."
