Primary Research on Crowd LLM Contamination & Specialist Verification
Peer-reviewed studies and federal/academic credential standards underpinning our workforce integrity audits.
Academic Crowd-Contamination Studies & Credential Standards
Artificial Artificial Artificial Intelligence: Crowd Workers Widely Use Large Language Models for Text Production Tasks
Veselovsky, Ribeiro, West (EPFL). Landmark empirical study demonstrating 33%–46% synthetic LLM usage among unproctored crowd workers.
Open Primary Study ↗Monitoring AI-Modified Content at Scale: A Case Study on the Impact of ChatGPT on AI Conference Peer Reviews
Liang et al. (Stanford University / ICML). Establishes corpus-level lexical distribution shifts used to flag synthetic reviewer cohorts.
Open Primary Study ↗National Plan and Provider Enumeration System (NPPES) NPI Registry
U.S. Centers for Medicare & Medicaid Services (CMS). Primary federal verification source for auditing physician and clinical specialist RLHF cohorts.
Open Primary Study ↗ORCID Persistent Digital Identifier & Institutional Affiliation API
ORCID Inc.. Used to verify doctoral publication records and university research affiliations.
Open Primary Study ↗Keystroke Dynamics as a Biometric for Continuous Contributor Authentication
IEEE Transactions on Information Forensics and Security. Grounds inter-keystroke timing and paste-burst anomaly detection against proxy account sharing.
Open Primary Study ↗Let's Verify Step by Step (Process Supervision Researcher Calibration)
Lightman et al. (OpenAI). Illustrates strict human researcher calibration loops required for reliable step-level math supervision.
Open Primary Study ↗Ongoing Workforce Re-Verification
Provider screening methods evolve rapidly; any provider deploying upgraded proctoring or credential checks may submit technical documentation for verification via /sponsor-or-verify/.
Independent credential verification, paste-blocking telemetry, and specialist retention benchmark. Zero frontier-lab ownership conflicts.
