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? Pangram flags 2.1% of chemistry originals versus 26.6% of theology originals in 2023–2025, with GPTZero showing the same ordering (1.1% to 15.2%). → Jonathan A. Karr Jr. 2026
q2 i? Non-STEM flag rates exceed STEM rates (p < 0.001). → Jonathan A. Karr Jr. 2026

Domain-level analysis of 2023–2025 original abstracts (Table 4) scored by Pangram and GPTZero at τ=0.50. The article reports "Pangram flags 2.1% in chemistry versus 26.6% in theology" and states non-STEM rates exceed STEM (p < 0.001).
"Flag rates on 2023 to 2025 originals vary sharply by domain at the same𝜏 (Table 4): Pangram flags 2.1% in chemistry versus 26.6% in theology; GPTZero shows the same ordering (1.1% to 15.2%)."
Discussion¶
Related Claims¶
- Elevated detector scores track long-token and Academic Word List density, with numeric and non-alphabetic token ratios correlating negatively — related
- No detection threshold simultaneously keeps original flag rates, light-edit capture, and AI-pool false negatives low — related
- A detector can achieve high aggregate accuracy while producing materially different over-detection rates across author groups — related
- Applied to 1,163 real master's theses, Pangram flagged 529 (45.5%) as containing AI-generated content, mostly at low-to-moderate levels — related
