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? Khalil and Er reported that Turnitin and iThenticate could detect plagiarism in less than 15% of essays based on existing literature. → Chunpeng Zhai 2024

q2 · i? · review · r2
Second-hand finding reported in the review's discussion of plagiarism concerns: Khalil and Er's studies of Turnitin and iThenticate detection of plagiarism in literature-based essays. The review attributes the less-than-15% detection rate to these authors and links it to lack of transparency in the algorithms driving plagiarism detection.
"Khalil and Er (2023) have reported that popular plagiarism detection tools, such as Turnitin and iThenticate, show a significant limitation in identifying plagiarism in essays that are based on existing literature. Concerningly, their studies reveal that these tools could only detect plagiarism in less than 15% of cases."
Discussion¶
Related Claims¶
- MOSS detected far fewer suspicious cases in Spring 2026 than in prior offerings, as LLM-assisted submissions lack similarity signals — related
- A linear mixed-effects model of detection error showed significant paper type, tool, and interaction effects, with underestimation largest for fully AI-generated papers and Pangram consistently producing the smallest errors — related
- On fully AI-generated papers produced with ChatGPT Deep Research, Pangram achieved 65% strict accuracy while Turnitin, GPTZero and Copyleaks classified essentially all papers as false negatives — related
- On hybrid and humanised AI papers, Pangram correctly identified AI content in 37 of 40 cases while GPTZero and Copyleaks performed poorly and Turnitin declined on humanised texts — related
- In a single-institution study, the joint system of Turnitin detection plus faculty judgement formally reported only 54.5 per cent of AI-generated submissions — related
- Evidence types differ systematically in probative value: detection outputs cluster at weak inferential force while admissions, observed exam behaviour and fabricated references carry the strongest profiles — related
